New Platonism is a Neo-Platonic philosophy developed by Alexander Curtis that uses the insights of modern science and mathematics to underpin the metaphysics of Plato’s philosophy and the „music of the spheres“ of his cosmology. Mathematically, the insights drawn upon are those of chaos theory, Fourier analysis and the application of mathematical logic to the philosophy of mathematics. Scientifically, apart from the occurrence of chaos theory in a plethora of fields that range from microbiology to planetary physics, the main insights drawn upon are those of evolution and the anthropology of human origins. In the following however, the emphasis is on the mathematical foundations, along with their ethical and theological connotations all introduced in a concise and reader friendly manner.

During the Middle Ages an abacus was used by merchants to perform the basic operations of addition, subtraction, multiplication and division, with numbers being represented by cumbersome Roman numerals. With the Renaissance this changed and Leonardo of Pisa (around 1170-after 1240), who is more usually known as „Fibonacci“, introduced to the West, Arabic numerals along with the handy tricks by which the numerals could be combined and manipulated on papier in a ways that made an abacus look clumsy and obsolete. Nevertheless the abacus had its advocates and an illustration of Arithmetic from the period shows the goddess with two mathematicians in front of her, one doing calculations on an abacus, whilst the other uses hand-written symbols on paper.

Hidden in this image is the question of whether numbers are nothing but operations of counting, represented, for example, by beads on a wire, or are they invisible entitites named by the symbols that represent them? This latter view makes „two“ that which all pairs have in common, „three“ that which all trios have in common, „four“ that which is shared by all quartets and so on. In the „step-reckoner“ or adding machine designed in 1671 by the Baroque philosopher, mathematician and historian, Gottfried Wilhelm Leibnitz (1646-1716), another question is tacitly raised, for translating the basic operations of arithmetic into systemised, mechanical steps, prompts the question of whether all mathematics can be so represented and defined.

In his *Foundations of Arithmetic* published in 1884, Gottlob Frege (1848-1925) showed that natural numbers could be defined in terms of classes so that the number two was the class of pairs, the number three the class of trios, et cetera. As classes could be defined in terms of logic, this suggested that the entire apparatus of mathematics could really be defined in this way. Setting about the monumental task of deducing from a limited number of logical axioms, the truths of mathematics, Frege worked for nine years on the first volume of his *The Fundamental Laws of Arithmetic.* This was printed in 1893, with the second volume appearing in 1903. Yet just as this second volume was going to press, Frege received a letter from Bertrand Russell (1872-1970), informing him of a paradox. This compelled Frege to add a postscript in which he admitted (1903, p. 253):

*For a scientific writer there is nothing worse that can happen than that after finishing a work, its foundations should be shaken. A letter by Mr. Bertrand Russell put me in this position just as this volume was in the last stages of being printed. *

Nevertheless after showing how the paradox, now known as „Russell’s Paradox“, could be constructed within his system (1903, p. 253-266), Frege concluded:

*The fundamental problem of arithmetic is: how are we to understand logical objects, in particular number? Although this problem has not been solved to the extent that I thought it was whilst compiling the present volume, I am nevertheless in no doubt that the way forward has been identified. *

Introducing a rule that outlawed the paradox, Bertrand Russell and Alfred North Whitehead (1861-1947) went on to develop an axiomatic system from which it was possible, without paradoxes and contradictions, to deduce the entire apparatus of higher mathematics. Complete with proofs, their three volume *Principea Mathematica,* was printed between 1910 and 1913.

In terms of logic, statements concerning an object that is present and of which a subject is making some form of claim, take the logical form of „there is an object x such that predicates … hold true of it“. The list of predicates that are true of the object concerned is then listed. In this way we can describe things that do exist such as tables and chairs, friends and relations as well as objects that do not exist, such as unicorns and mermaids.

This method of breaking down and analysing out the import of what we say is the beginning of what is known as „Russell’s Theory of Descriptions“ and was important to Russell as he wanted to show that we can talk about things that may exist without, by the very act of imagining them, implying that they do exist and it was in process of ironing out the anomalies that can come into being when we talk about unicorns and other fictional entities that Russell stumbled on the paradox that bears his name. Yet when we speak of unicorns and mermaids there is in fact more going on than meets the eye. In logic this shows itself via the notion of a class or set of things. Two things belong to the same class when they are in a certain respect similar, in other words two inanimate objects with four legs that support a flat surface, are tables and belong, along with all other tables in the world, to the class of tables, with their „tableness“ being what makes them similar. The notion of classes is of utmost importance for the Theory of Descriptions as in order to say that unicorns do not exist, it is necessary to define the class of unicorns and then to say that the class of unicorns has no members. Thus where subject/predicate logic says „there is a physical object x such that …“, the same thing stated using the logic of class membership says „there is a type of logical object x such that … and the object x is called … and the following objects are members of it“. In discussing things that do not exist reference is made to the similarities in the world that do exist. While unicorns and mermaids do not exist, the animals out of which they are formed as composites do exist.

Thus there are horses and narwhals and goats and also classes of horses and narwhals and goats. Likewise horses and narwhals and goats can be defined in terms of their characteristics, such as having a mane, four legs a beard and a horn *et cetera*. These components in turn can be defined in terms of other things and properties so that the description of under what circumstances it is that a creature is called a horse, or a narwhal, or a mermaid gets ever more long-winded and unwieldy. The point is that everything we say about the world is done with reference to the similarities that the predicates we use tacitly assume. In terms of class membership, when we say that object „a“ is similar to object „b“, what we are saying is that objects a and b are both members of the same class and partake of the similarity that membership of the class concerned implies. In logic this is expressed by writing:

(E x) (y): y ‚ x

which is shorthand for:

*there is an object „x“ and an object „y“ which are such that y is a member of x*

This shows that as something that each individual member of a class partakes of, the class itself is in some way independent of its members, which are liable to fluctuate in number. Thus in the above, object „x“ can only be a logical object and the admission of logical objects into the position denoted by the brackets means that they are accorded some kind of existential status. This is to say that, given the existence of horses, goats and narwhals, there is such a thing as the class of unicorns even though the class itself being a so-called „empty set“, is devoid of members. Russell was more than aware of these ontological implications but viewed the inclusion of logical objects into the quantifying position of logical formulas as an „as if“ trick which though it looked as if it made an existential claim, in fact did not. The reason for this was that for a logical system to be able to produce the truths of higher mathematics, it is essential that classes be accorded some kind of existence as the definitions necessary cannot be expressed as the system does not recognise them as valid. Russell’s unwillingness to accord classes any form of existence arose from his stumbling on the at first sight innocuous „class of classes that are not members of themselves“. As a sphere is a physical object, the class of spheres is not a member of itself for it is a logical object and is not something that can occupy space. Yet as Russell realised, the class of classes that are not members of themselves is a member of itself if it is not and is not a member of itself if it is and it was this class that upset Frege’s sytem. In *Principea Mathematica*, the class of classes that are not members of themselves is prohibited by Russell’s Theory of Types which with respect to class logic outlaws the formulation of self-referential expressions. For Russell the whole of mathematics was thus an as if trick that only by chance and „somehow or other“ had any connection and relation to reality. Following the publication of *Principea Mathematica,* the work of Russell and Whitehead was continued by others, including Willard van Orman Quine (1908-2000). Unlike Russell, Quine argued that saying „there is a class of thing x such that …“, is just as much an ontological statement as saying „there is a physical object x such that …“ and that this commits one to accepting that both forms of entity, the physical and the logical, exist. Ultimately this position draws upon and admits that the similarity that we perceive in the world at large does appear to exist and so has no qualms about according classes an existential status. This position is seen as being equivalent to the position adopted by Plato who saw the „tableness“ of a table as an ideal, universal table that existed independently of any particular table and which in Plato’s metaphysics provided a form of template from all the tables that did exist were made. For this reason this view is often described as „Platonic“. Like Quine, the Czech mathematician, Kurt Gödel (1906-1978) also saw mathematical objects in an analogous way to Plato and accorded them an existence that was unrelated to human activity and humans doing mathematics. This means that our mathematical intuition is a response and an adaptation to the world and not an invented construction that has no counterpart in external reality. For Gödel:

But despite their remoteness from sense experience, we do have something like a perception also of the objects of set theory, as is seen from the fact that the axioms force themselves upon us as being true. I don’t see any reason why we should have less confidence in this kind of perception, i.e. in mathematical intuition, than in sense perception.

A little later he says:

Evidently the „given“ underlying mathematics is closely related to the abstract elements contained in our empirical ideas. It by no means follows, however, that the data of this second kind, because it cannot be associated with actions of certain things upon our sense organs, is purely subjective, … Rather they, too, may represent an aspect of objective reality, but, as opposed to the sensations, their presence in us may be due to another kind of relationship between ourselves and reality.

This „other kind of relationship“ is the vast heritage of behavioural responses that we genetically inherit and learn in the womb and during our first years of life and it is this that makes the axioms of geometry and set theory „force“ themselves upon us as being intuitively true. For David Hume however (1711-1776), the similarities in nature that we perceive were inferred by subjects in a manner that was purely inductive, via a step by step process that was based solely on observation. Yet as Russell himself later showed, this is however only half the story for „seeing“ involves assuming that there is and will be similarity in the world. Rather than passively acquiring the habit of perceiving similarities in the world, we actively seek them out and build our conception of the world out of the similarities that we have in part actively projected onto the world. We see similarity in the world because we have to. Nevertheless if there were no similarly in the world we would not be able to make either head nor tail of it. Thus although there must be similarity „out there“ in the world, in any particular instance of seeing and understanding, the similarity that we see is something that we have assumed. This was the conclusion reached by Russell in his book, *Human Knowledge* (1948). Published after a lifetime of investigating and trying to identify what it is that our experience and knowledge of the world is based upon, *Human Knowledge* was the closest that Russell got to writing a systematic account of the world. At the end of the work he pragmatically concludes that all human knowledge is based on the assumption of there being some form of similarity that exists „out there“ in the world although there is no logical law that stipulates that this is and must be the case. Nevertheless, though we believe blindly and must believe blindly, there is still justification in assuming that the world at large has organised this state of affairs so that it is to our advantage. In New Platonism this is expressed by wholeheartedly asserting the existence of classes and seeing the entities of mathematics as objective reflections of an aspect of external reality.

Despite the systematic rigour with which the axioms, theorems and proofs of *Principea Mathematica* were expounded, fundamental questions still remained. Was mathematics an objective facet of reality or was it nothing but a set of rules invented by humans who then devised ways by which their rules could be applied to the physical world in which they found themselves? Were the theorems derived in *Principea Mathematica* all the truths that mathematics had to offer, or were there other unprovable truths that could be formulated but not proven? Here Gödel found a way of reformulating Russell’s paradox that amounted to the statement:

The class of all statements which are free of contradiction contains a class of statements which are either free of contradiction and are unprovable or are provable but contradictory.

As the contradictions mentioned in the last phrase would render any such system contradictory, “Gödel’s Theorem” is a definite proof that mathematics is incomplete. This means that in any complex system of axiomatic logic such as *Principea Mathematica,* there will always be mathematical truths which whilst they can be expressed by the symbols of the system and are true, can never be derived or proven using the proofs that follow from the axioms of the system. In addition to establishing that mathematics was incomplete, Gödel also showed that no mathematical system can prove that it itself is free of contradiction. Though there remained the possibility that provable statements might somehow be distinguishable from unprovable ones, this was disproved independently by the American, Alonzo Church and by the British mathematician, Alan Turing. In all of these works, concerning what can be proved and disproved in mathematics, what was assumed and shown, was that mathematics is a symbolic activity. This means that even proofs and theorems that do not consist of numbers, can be redefined in ways which enable them, on a higher level, to be symbolised by numbers. This makes all mathematical truths expressible by such systems, a question of numbers. With mathematical truths and their proofs becoming a question of numbers, the way is opened for the establishing of mathematical truth to become a question of computing and in considering the decidability of mathematical truths, Turing postulated „a universal machine“ capable of carrying out mathematical operations. This he envisaged as being able to read and write binary notation, so that equipped with bands of tape, it could be read, write, erase and move over sequences and stop at certain points. Like a typewriter that can shift between upper case and lower case letters, the machine could also shift between different modes so as to perform different operations. With respect to the decidability of mathematical statements, which is to say the numbers encoding such statements, in their articles, both Church and Turing used what is known as the „diagonal argument“ developed by Georg Cantor (1845-1918). This Cantor had developed to show that mathematically, there are infinite numbers of infinite collections. The demonstration consists in making a theoretical list of all rational numbers between 0 and 1. Omitting the fractions with cancelling factors this results in a list that begins:

1/2, 1/3, 1/4, 2/3, 1/5, 2/5, 3/4, 1/7, 3/5, 1/8, 2/7, 4/5, 1/9, 3/7, 1/10 …

If these are expressed as infinite decimals the list becomes:

1 0.**5**000000000000000000000000 …

2 0.3**3**33333333333333333333333…

3 0.25**0**0000000000000000000000 …

4 0.666**6**666666666666666666666 …

5 0.2000**0**00000000000000000000 …

6 0.16666**6**6666666666666666666 …

7 0.400000**0**000000000000000000 …

8 0.7500000**0**00000000000000000 …

9 0.14285714**2**8571428571248571 …

10 0.600000000**0**000000000000000 …

11 0.1250000000**0**00000000000000 …

12 0.28571428571**4**2857142857142 …

16 0.100000000000000**0**000000000 ..

17 …

18 …

From this list, Cantor then took the diagonal number: 0.5306060020040180 … and systematically changed each digit, by for example, adding one and changing any nines encountered to zeros. In the case of adding one to the above diagonal number, the number that results is: 0.6417171131151291 … This cannot itself be a rational number as at the first decimal place it differs from the first listed rational number by one. At the second decimal place it also differs from the second rational number by one. From any other chosen number, x, it likewise differs, at the x^{th} decimal place by one. As the list contains all rational numbers, the number thus generated cannot be rational. Moreover any such list can always be used to serve as a means by which another number, not on the list, may generated. Accordingly, there are Cantor argued, more irrational numbers than the already infinite number of rationals. In his *On Computable Numbers* of 1938, Turing generated numbers that represented the decidability of mathematical propositions including some produced by the diagonal argument. He then showed that the diagonal method could not be mechanised. The numbers generated by the argument were therefore beyond reach of the system. Yet as the machine was a universal machine, this was a general proof of undecidablity within all systems. While the incompleteness of mathematics, which is to say of systems of symbolic mathematics, is sometimes presented as if it were some sort of tragic loss there is no reason to see it this way. Rather it simply shows that whilst one can divide the world into parts and extract a system of mathematics that deals with the relationships pertaining between such parts, there will always be something indeterminate that, lying out-with the confines of whatever system one has chosen to set up, will accordingly be unpredictable. Philosophically this implies that whilst it is not inappropriate to divide the world up, what is learned as a result, will not and never can be, the whole truth. Not dividing the world up into parts that can be investigated means that we have nothing to say about the world as, as seen, language works by seeing the world as being composed of parts about which things are said due to some parts being similar in certain respects to other parts. For Gödel:

The set-theoretical paradoxes are hardly any more troublesome than for mathematics than deceptions of the senses are for physics.

By this, Gödel means that paradoxes such as Russell’s paradox are similar to phenomena in the physical world such as a stick that inserted into water appears as if bent at the water’s surface or in a desert, the phenomenon of a mirage. Published in 1931, only eight years later, Gödel’s „Incompleteness Theorem“ and the ardently held debates on the nature of mathematics, suddenly acquired a practical relevance that soon proved to play a not insignificant part in altering the course of the Second World War. As radio contact was quickly found to be essential for modern warfare, the perennial problem was of how to make messages incomprehendable to all but the intended recipients. In 1918, the electro-technician, Arthur Scheribus had devised an encryption procedure that in 1926 had been used for military purposes and which, following Hilter’s rise to power was successively improved so that by the outbreak of the war, its use was an integral to military and diplomatic comunication. The revised device was the celebrated „Enigma“, whose encrypted messages were believed by the Germans to be uncrackable.

Although „Turing’s „Universal Machine“ was hypothetical, its principles formed the basis for his crypto-analytic work at Bletchley Park where in 1939, he completed the design for a computing device that systematically searched through the encryption possibilities of Enigma encoded messages. Known as a „Bombe“, when in operation the machine made a ticking noise reminiscent of the time fuse on an explosive bomb.

Although Turing’s Bombes could work much faster than any human operator, speed was nevertheless only half the secret for had the Bombes worked systematically through every available possibility, the intercepted messages would still have taken so long to be deciphered that the advantage gained by knowing the message’s content would be lost or significantly offset by its being out of date. Yet from the investigations into the foundations of mathematics carried out before the war, Turing knew that in formal systems, truth could be acquired at the expense of certainty and completeness. Proceeding step-by-step in search of a set of encryption settings that was certain, was similar to wanting a step-by-step proof in mathematics. If the demand for perfectly justified methodical steps was relaxed or abandoned, large numbers of unlikely alternatives could be eliminated leaving a much reduced number of more likely combinations which the Bombes could work through in a time that did not overtly comprise the actuality of the information. In this way, through the prompt decipherment of information at Bletchley Park, Turing and his colleagues are reckoned to have knocked two years off the length of the war.

In Russell’s Theory of Types and the other rules according to which classes may be defined and postulated are such that while things exist and may be said to exist, existence itself is not a predicate but rather is an operative symbol and states of affairs in the world either exist or do not exist and so either are or are not. This means that at the level of classes, existence is not something that can be talked about. This is because it cannot be inserted into the quantifier position of a logical statement, as it is not an object nor can it be put into the predicate position, as it is not an adjective. At first sight this makes it look as if the existence of God is not something that can be proved as traditional proofs of God involve saying that God is good and God is great and that in order to be perfectly good and perfectly great, he must also exist as otherwise he would be imperfect. God’s existence is thus something that is necessary with „existence“ being something of which it is maintained that the predicate „is necessary“ holds true of, with it being however precisely this that class logic outlaws. Yet just as Gödel’s Incompleteness Theorem re-introduces Russell’s Paradox by, instead of talking about classes, talking about classes of statements that are true, provable or un-provable, so too Gödel saw that the old arguments concerning the necessary existence of God could be re-introduced with renewed validity. Like Russell, Gödel saw the similarity and continuity that we encounter in the world and as essential for our survival. Moreover, as observed by the Austro-British philosopher Sir Karl Popper (1902-1994), for any problem there are always good and bad solutions and as all life-forms, as long as they live, are engaged in the solving of problems, this gives an objective basis by which the concepts of good and bad can be defined. This in turn makes the preserving of the similarity and continuity that characterises the world, integral to any conception of the Good. Reflecting this, with reference to his proof, in his philosophical notes Gödel wrote:

*The fundamental philosophical term is cause. This involves: will, power, pleasure, God, time, space. The affirmation of existence is the cause of the world. The first being: to existence, there comes an affirmation of existence. From this it further follows that as much existence as possible should evolve – and this is the ultimate reason for diversity *(variato delectat).

*Harmony entails more existence than disharmony, for the opposites negate their existence. Regularity consists in agreement, for example the same angle, the same colour.*

*Variato delectate *means “variety delights”. Today, life on Earth features an unparalleled range of diversity that consists of some 5 to 9 million different species. The ways in which animals, birds, fishes and insects interact both with each other and with the rest of the environment are highly complex and only partially understood. Although we are often unaware of it, many of these interactions are such as to provide invaluable services to mankind and the stability of the natural world thus constitutes an immense package of similarity and continuity on which human civilisation is completely and utterly dependent. Never publishing his proof, Gödel shared it in 1970 during a period of illness from which he thought that he might not recover. His reluctance to publish was due to his not wanting it to be seen in the same light as traditional proofs. Rather he wanted it to be seen as part of an apparatus of speculation that arises whenever we begin to think seriously about the world. In view of the fundamentally essential role of similarity and continuity in human life and thought, considering what is likely to happen when the eco-systems of the world get out of hand is not only topical but gives Gödel’s proof a new measure of relevance when we consider that without the Good as conceived of by Gödel, life as we know it would collapse. An honest and informed striving for a good that is beneficial for all people both now and in the future is essential for our survival it and moreover automatically prescribes an environmentally responsible mode of conduct as everything we do has implications for the environment and for those who come after us. This however raises questions about how are we as individuals to know what is good and what is not good. In striving for the Good what is permissible and what is not and who i) decides and who ii) is responsible when well-meant plans go wrong?

For any deed undertaken or any mode of conduct lived out there is always the danger of it being overtaken by events and contexts whose complexity and knock-on effects we fail to apprehend. The immense and profound gravity of this problem was considered by Dietrich Bonhöffer (1906-1945), who was a priest and objector to the Nazi regime. Banned first from speaking and then from writing, Bonhöffer saw that in a regime such as Hilter’s, pacifism, by virtue of not rocking the boat and not presenting the system with any significant problems, over time, was indistinguishable from someone who, by merely „doing their duty“, simply wanted to get by without killing anyone and without being killed and apart from not out-rightly embracing Nazi ideology did not otherwise undertake take any form of moral stand. Bonhöffer therefore came to the conclusion that in such a case focused violence was the only option available. Yet here a host of difficult questions arise. In making an effective act of resistance is it justifiable to kill and if so, is the unintended killing of innocent people also justifiable? In cases where action taken resulted in the unintentional killing of innocent people, Bonhöffer saw the crippling guilt that could be engendered, as something that could be overcome through trust in the all-forgiving Grace of God. This and the reconciliation that God initiates between man and himself, he saw as being rooted, not in Christ’s death upon the cross but rather in God’s decision to become human and descend to Earth in the first place. Taking this thinking further, one can observe that, as only a human being who has been wronged can forgive a human being who has done wrong, it is for this reason that God must be thought of as sending himself, in the form of his only Son, down into the world to take upon himself the sins of the world so that those who have sinned can be forgiven by him on a human, one to one, personal basis. Repeating the pattern set up by Gödel in his Ontological Proof, this observation can be rendered in terms that make it necessary, so that if the Good is sought, there is of necessity a God and of necessity there is forgiveness and accordingly, in some sense, a human manifestation of the Divine that enables forgiveness to be granted, as this is the only way that human beings who have done wrong can receive forgiveness and experience the absolution of their guilt. Here the pivotal realisation is that in spite of all the science and mathematics we have at our disposal, we are emotional beings and if we are to have a future, we must re-define ourselves both emotionally and intellectually and on both levels re-establish a relationship and rapport with that which lies over and above us. Despite his being forbidden to write, from 1940-1943 Bonhöffer worked on a book of ethics and theology in which he intended to provide a new theology for the Germany that would come into being once the war had ended and the dictator had been removed. Becoming involved in a resistance group and knowing that he might at any time be arrested, Bonhöffer hid the various parts of his writings in his garden, whilst other parts, although confiscated by the Gestapo nevertheless survived. Early on in the work, Bonhöffer diagnosed the nothingness into which he saw the western world as falling:

*This nothingness into which the West is sliding is not the natural end, the dying, the sinking of a flourishing community of peoples. Instead it is again a specifically western nothingness: a nothingness that is rebellious, violent, anti-God, and anti-human. Breaking away from all that is established, it is the utmost manifestation of the forces opposed to God. It is nothingness as God; no one knows its goal or its measure. Its rule is absolute. It is a creative nothingness that blows its anti-God breath into all that exists, creates the illusion of waking it to new life, and at the same time sucks out its true essence until it soon disintegrates into an empty husk and is discarded. Life, history, family, people, language, faith – the list could go on forever because nothingness spares nothing – all fall victim to nothingness. *

Gödel’s Ontological Proof puts this insidious all-consuming nothingness into context when one realises that modernism must embrace a doctrine of nothingness as otherwise it would be forced to acknowledge God and this goes against the modernist mantra of „… but we know better“. This is underscored through the use of machines in every aspect of our lives and through the turbo-charged nature of consumer culture and globalisation which combine to further alieniate us from the basic realities of life and make us indifferent to the circumstances under which the things we consume are produced and the knock-on effects of their their use and production. Over the course of the twentieth century this has led to a culture of institutionalised cynicism which more recently has been filled out by a form of cultural relativism. The two combined result in an attitude in which anything that strives for value is dismissed. By not rocking the boat and not posing any fundamental challenges, all this supports the modern world’s, at times tacit and at times blatently declared credo that the point of life is to make money. The relevance of Bonhöffer’s message is that the credo that the point of life is to make money, is a godless derivative of the protestant low church attitude to life. In protestant low churches, the tacit implication is that the point of life is to live in a manner that will ensure that one is admitted to heaven. This makes life a test, with the joys of this life being but a passing irrelevance. In like manner, according to Neo-Liberalist, *Homo oeconomicus* view of what a human being is, life is about earning and spending money and nothing else. In this view, which is descended from the low church view, God is rejected and heaven is replaced with the idea of money in the bank. In theology, Bonhöffer is therefore important as he explicitly denies that life and the human body are merely the means by which the test of a person’s worthyness for admittance into the Kingdon of Heaven is conducted. Rather life and the human body are ends in themselves and this means the joys of life are the joys of God and as such are to be cherished and enjoyed both in the present and as memories. A Lutheran, Bonhoffer’s *Ethics* provides a fully worked out means by which the low-church attitude to life can be called into question and with it, the absurdity and utterly unfounded nature of the *Homo oeconomicus* myth further exposed. Regardless of how unwanted it may be, the *Homo oeconomicus* myth is the abandoned orphan and unruly child of low church thinking. For Bonhöffer the omnipresence of Christ in the world of today was a central truth which he saw as being the departure point for all else. Accordingly the word of God was not „forever“ but rather was ever omnipresent, in the here and now of today. For this reason Bonhöffer saw theology as being perpetually rewritten in order that it speak the language of the present. This however did not mean that compromises had to be made with other forces at large in the world, such as National Socialism. Of particular relevance here, Bonhöffer advocated a „natural life“ in which:

*Reason perceives the universal in what is given, as reason perceives it; is also something universal. It embraces the whole of human nature. Reason recognises the natural as the given, as what is universally established, independently of being able to prove it empirically. *

*A decisive consequence follows from this. The natural can never be a construct of some part or some authority in the fallen world. Neither the individual nor any community or institution in the preserved world can set and decide what is natural. *

Inherent in the Natural is an acceptance that things can be ends in themselves and as shall be shown, this is inherent in chaos theory, in which from out of chaos, order emerges and enables the coming into being of further forms of order of ever growing complexity and intricacy. Inherent in this is the fact that all things are interrelated, for each layer of order perceived rests upon an underlying layer.

In seeking a way of thinking about the Divine that is scientifically grounded, explains phenomena and yet is also humble and does not dogmatically deny the existence of that which it cannot explain, it is instructive to return to a metaphor for God developed by Nicholas of Cues (1401-1464), otherwise known as Cusanus. This provides a means by which the coming into being of a new world can be followed, so that from out of the disorientation, doubt and chaos that the nothingness identified by Bonhöffer leaves behind it, a new view of life and the world can be brought into being. With a single sweep, a circle can embrace all that lies within its radius, whereas straight lines can never do this but rather can only enclose an area when instead of there being but one straight line there are three. Traditionally therefore the circle and sphere are associated with the divine, whilst straight lines, along with the figures and solids that can be made from them, are seen as earthly. Where straight lines are easily measured, all that is circular is elusive and somehow otherworldly and in order to quantify something that is circular or curved, reference must be made to π. Given a right-angled triangle, the length of whose lesser sides are given by whole numbers, the length of the hypotenuse is given, either by a whole number (as in a 3,4,5 triangle) or by an irrational root (as in a 1, 2, √5 triangle or a 1, 1, √2 triangle). Although irrational and with a process of enumeration that goes on forever, these irrational’s and a host of associated irrational numbers, such as phi, which characterises the Golden Section and towards which the Fibonacci sequence tends, are nevertheless not irrational in the way that π is. This was first realised by Cusanus who saw that π is what mathematicians now call a „transcendental number“. This means that the irrationality of π and other transcendental numbers is different from and transcends the irrationality associated with the diagonals of geometric figures. In what mathematicians call a polynomial equation, rational and irrational numbers can be characterised by means of whole numbers that reduce the number concerned to zero. Thus where √2 is defined as x^{2} – 2 = 0, transcendental numbers cannot be characterised in this way and are seen as belonging to a number class of their own. ). For Cusanus, no earthly square could ever be equated with the insensible perfection of a circle. The wish Cusanus said, for there to be such an equality was a result of our seeing things with mental eyes so that, apprehending the divine, we were inclined to forget the limitations of the corporal world. Cusanus saw the differences between rational and irrational numbers as indicating something of the differences between our human powers of rationality and the all-encompassing, ineffable nature of God. For Cusanus, God could not be known or apprehended through rational means but only once rationality had been dissolved and it had been accepted that when it comes to God and the nature of God, we known nothing. This recognition however enabled God to be approached by other means. The purpose of philosophy was therefore to show that when it comes to God, we know nothing. Likewise, in mathematics, where rational numbers reflected the reality of the material world, irrational numbers, by showing the shortcomings of our day to day rationalism, pointed to the divine. In this way Cusanus saw Christ’s earthly nature as melting into the eternal circle of his divine nature, in exactly the same way that an infinite polygon fades into a circle.

In order to escape the modernist void of nothingness described by Bonhöffer and see how things can be ends in themselves, it is instructive, against the background of Cusanus‘ speculative theology, to imagine a rotating disc. This has a smaller disc is mounted at a point one radius length in from its circumference and when as the larger disc moves, the smaller disc rotates in the same direction. With this simple apparatus a series of thought experiments can then be conducted.

__Experiment 1__

If the two discs both rotate at the same speed and so execute the same number of rotations in a given period of time, they will be synchronised and a particular point on the smaller disc will, after one revolution, meet up again with a particular point on the larger disc. If the point on the smaller disc lights up whenever it brushes with the circumference of the larger disc then the impulse of light will always be at the same place. Taking this point as defining 0°, if the speed of rotation of the smaller disc is increased then the light will no longer light up at 0°, for with each revolution of the larger disc, the smaller disc will complete more than one revolution so that the flashing light will move around the circumference of the larger disc. As the speed of rotation is increased, this movement around the disc will get faster and faster. At certain point the light will return to the 0° point and if acceleration is stopped, will remain there emitting a rhythmic pulse. 180° away from zero it will also be flashing rhythmically and from this it can be deduced that the speed of rotation of the smaller disc is twice that of the speed of the larger disc. Progressively increasing the speed of the smaller disc will result in the same phenomena occurring again, only when the light returns to 0°, instead of there being one other stable point at which the light flashes, there will be two, each 120° away from 0°. This can be carried on until the number of stable points is infinite and instead of there being flashing lights, the arc of a circle moves around the circumference, the length of the arc being related to the glow time of the light. This thought experiment shows how the whole numbers of the ratios 1:1, 1:2, 1:3, 1:4, *et cetera* that characterise the rotations of the smaller disc relative to the larger disc, act as what mathematicians call „strange attractors“ – points of stability that arise in what is otherwise a sea of perpetual change.

__Experiment 2__

While Experiment 1 is so straight-forward as to be almost banal, it nevertheless introduces the concept of a strange attractor and sets the stage for a scenario in which the unexpected comes to the fore and the predictably straightforward world of conventional mechanics is by-passed. If the larger disc is said to react to the increasing speed of the smaller disc and following a certain delay, to likewise increase in speed, then the situation becomes complex with the two discs behaving as if in a race with each other with victory frustratingly slipping out of sight once the lead has been gained. For although the smaller disc can always go faster than the lager disc, the larger disc can always catch up with it. This makes the increased speed of the smaller disc relative to the larger, something that continually grows and then diminishes. On a graph known as a logistic parabola, this can be shown by plotting the increase in speed of the smaller disc is plotted against the period of time over which it is accelerated and made to rotate faster and faster. Although the acceleration of the larger disc is not shown, its effects on the speed of the smaller disc are. On the logistic parabola, the parameters are rigged so that the graph is a square in which the curve begins and ends at zero and on the y-axis the maximum attains a value less than 1. As the smaller disc is accelerated, compared to the larger disc it completes ever more rotations, so the curve rises steeply upwards. Then, as the larger disc begins to accelerate and likewise completes ever more revolutions, so this steeply rising curve flattens out and the maximum is reached. With this, the smaller disc is no longer rotating faster than the larger disc and the difference in speed begins to diminish. Although the speed of the smaller disc is still being progressively increased, that of the larger disc is also increasing and as the cycle of the larger disc is behind that of the smaller, the larger disc will, from this point on, always be going faster than the smaller disc and so the difference in speeds between the two will always be getting smaller until the two are both going at the same speed (this being of course a much increased speed compared to the speed than when the was experiment started). As in Experiment 1, there are stable points, the first of which is to be found shortly after the curve reaches its maximum. Here, at x = x*, if acceleration is stopped, a stable situation will result with the light on the smaller disc always flashing at the same point.

This situation is usually introduced with reference to a population of rabbits that is preyed upon by a population of foxes. As the rabbits increase, so too does the number of foxes that prey on them until there are so many foxes that the number of rabbits begins to fall. There then comes a point when there are more foxes than can be sustained by the rabbit population. The number of foxes therefore declines, which with a delay factor, enables the rabbit population to grow again. The next year there are more rabbits and the number of foxes again begins to increase until the population is once again decimated where upon the foxes again find themselves without food. If these ups and downs are plotted on a logistic parabola, the curve that represents the rabbit population rises upwards until it reaches a maximum. Then at x*, a stable population results, preyed upon by a likewise stable population of foxes. If however, the rate at which the rabbits reproduce continues to increase, or, returning to the case of the two discs, the smaller disc is accelerated further, then f(x*), the stable point that is associated with x*, will become unstable and dissolve. In the case of the rabbits, the population decreases, in the case of the two discs, the difference in rotational speed lessens until at x = 1, there is no difference and despite the increased rate of reproduction, in the case of the rabbits, there are no more rabbits.

__Experiment 3__

In order to see what happens when the situation outlined in Experiment 2 is continued and the system is subjected to further acceleration or an increased rate of growth, the f(x) values from Experiment 2 are taken and are fed back into the function to get f^{2}(x) values. On the lower of the two graphs shown below it can be seen that instead of one maximum there will two, separated from each other by a trough. After the trough and before the second maximum, the increasing rate of growth leads to the curve rising upwards in a way that is formed from two scaled rotations of the curve on the first graph, at the point where, after the maximum was reached, the curve began to dip down towards f(x*). Here the scaling factor is 2.618… or phi + 1, where phi is the number associated with the Golden Mean.

As each of the two segments of the new curve is similar to the original segment, the same dynamics apply but at at two points on the curve instead of one. Thus f(x*), which was once an attractor, becomes instead a repellor and pushes the values of f(x) either down to f(x_{0}) or up towards f(x_{1}), so that f(x_{0}) and f(x_{1}) become the new attractors and the new stable or fixed points of the system. In the case of foxes and rabbits, this corresponds to a case where, due to an increase in the breeding rate of the rabbits, the once stable population at f(x*) has dissolved and instead there is a maximum at f(x_{1}) and minimum at f(x_{0}) with the population oscillating dynamically between the two extremes.

__Experiments 4, 5, 6, …__

To see what happens when acceleration is continued, the results of Experiment 3 are fed into the f(x) function to result in f^{3}(x) and the same can be done repeatedly to result in f^{4}(x), f^{5}(x), *et cetera*. In each case, the number of stable points in the system, which in chaos theory are known as „orbits“, doubles, so that the number of orbits generated by f(x), f^{2}(x), f^{3}(x), f^{4}(x), f^{5}(x) is 1, 2, 4, 8, 16, *et cetera*. This form of what mathematicians call „bifurcation“ is known as „period doubling“. On the logistic parabola, another form of what mathematicians call „bifurcation“, is „period-trebling“ in which stable orbits of 3, 9, 27, *et cetera *are generated. The phenomena can however also produce five-fold, seven and nine-fold bifurcation’s. Returning to the rotating disc, this means that as the two discs are progressively accelerated the stable orbits that arise are those of the number series 1, 2, 3, 4, 5, 6, *et cetera* and from the points where the light repeatedly shines at the same place, triangles, squares, pentagons, hexagons *et cetera* can be constructed. Continued *ad infinitum* the process of drawing plane figures with ever more sides results in a circle. If on the logistic parabola, the scaling factors are compared from one graph to the next it will be seen that they rapidly tend towards a constant of 2.5029…, which known as alpha, is integral to chaos theory. The point at which bifurcation results in an infinite number of stable orbits, is chaos as instead of having a finite number of stable orbits, or fixed points between which the system oscillates, there are an infinite number. In a chaotic state, while a system is recognisable and has its usual form, aspects of its behaviour are unpredictable. Once a chaotic state has been reached, if the rate of growth or acceleration is increased still further, then it will be found that from out of the chaos, a new series of stable orbits will arise, exactly as before and these again can be increased and likewise, from them, a new state of chaos brought forth out of which further stable orbits can be made to arise. In this way, from out of chaos, order can arise and equally, chaos can be made to reappear and this branch of mathematics is known as chaos theory. This shows how behind the supposedly staid and solid strange attractors of Experiment 1, there is whole world of dynamic interactions in which systems no longer behave in a linear fashion.

To relate these experiments to the world of space and time, the experiments above are repeated with the revolutions of the points around the circumferences of the two discs being shown as sine curves. Where a circle shows the route taken by a point as it moves around the circumference, a sine curve shows how the point oscillates away from and then towards a straight running through the centre of a circle. By virtue of this repetitive movement the points on the line can be seen as representing successive moments in time that visually the sine curve represents the rotational movement of a point along a time axis, t.

If as in the above experiments, the point rotates continually around the circumference, the result is an endlessly undulating wave. Depending on the size of the circle and its speed of rotation, sine curves can be of different amplitude and can have different frequencies. The different curves can however be added together to create a complex curve, which can at any time be broken back down into its component curves. In the graph below the three monotone curves of different amplitude and frequency have been added together to result in the red curve.

Although the sine functions that characterise sine waves are what mathematicians call „continuous“ and generate curves that extend out to infinity, by a technique which involves considering all possible sine functions, particular functions can be introduced and terminated as required. This means that anything drawn graphically on a graph, regardless of whether it consists of curves, straight lines or combinations of the two, can be defined in terms of sine waves. This is shown in music where any sound imaginable can be synthesised in terms of a varying one-dimensional value and in DVD technology where visual images are reduced to frequencies that occupy two dimensions. Taken to its most minimal extreme this results in Dirac’s function which at zero is infinite, whilst elsewhere it is zero. In mathematics this way of modelling things by means of sine waves and their functions is called Fourier Analysis and is just as true in three dimensions as it is in one and two. Accordingly, if the above experiments are repeated and from the rotating circles, sine waves are extracted, from the rates of growth that resulted in the formation of stable points, stable sine waves will result with frequencies that are expressible in terms of whole numbers. Using these stable building blocks, anything desired can then be constructed so that through the combination of chaos theory and Fourier analysis, a convincing accountof the universe can be built up and which coincides with modern physics seeing the universe as undulations of energy in space. In this account, the stable points of chaos theory are what underwrite the similarity of the world as we know it.

As the stability that characterises life and the universe is dependent on the rates of growth and acceleration remaining constant and these are often inter-linked with each other, the universe is fundamentally complex and has an organic, living character to it. Wanting to express this aspect of the world, in his *Timaeus,* Plato refers to the universeas a whole as an animal and modern science now sees non-linear dynamics as being everywhere. It is at work at various levels in our bodies and those of all other living things, it is at work in to the dynamic interactions of animal populations with each other and is what lies behind populations of viruses, bacteria and other microbes. Chaos theory governs fluid mechanics and underwrites the stability of our Solar System. Even though it involves only numbers, its applications are so numerous that the constant associated with it, delta, is known as the „universal constant“ with delta being related to the scaling-factor, alpha already encountered. Once matter has come into being, chaos theory can be rightly said to be that which underlies the development of all that the universe contains. Chaos theory thus enriches and gives new meaning to Cusanus‘ metaphor of God. It also explains and puts into context Plato’s conception of the Same and the Different with which in the *Timaeus*, the Demiurge begins to fabricate the universe. This is close to the conception of the universe arrived at by modern physics in which, before the big bang, the universe is seen as having been a supra-compressed, supra-hot and supra-ordered mass of unimaginable density whose perfect order was suddenly shattered. Resulting in an exploding universe, the shattering’s ultimate goal is to acieve a state of maximum entropy. Not chaos, entropy is a state in which nothing can happen because everything that could happen, has happened. Although everything in the universe will one day be reduced to a small number of basic particles whose spatial positions and configurations are perpetually changing so that life and continuity will be impossible, as Plato perceived, such a form of perpetual change is also a form of continuity, so that within the Different there is a hidden element of continuity. Equally in the Same there is also an element of difference as in order to manifest itself, Sameness must in some way have different facets which are nevertheless part of a whole. Although it is a fact that one day our universe will become nothing but an evenly mixed collection of basic particles, from a point of view within the universe, this this is not its point. Rather, the point is the journey from a supra-hot and supra-condensed mass towards a state of extruded maximum entropy. Along the way, order and chaos dance around each other, bringing patterns into being that are at times beguilingly simple, at times breathtakingly complex. Like a firework, it is not important where the burnt-out shell of the rocket lands but on how it looks as, once it have been shot up into the air and exploded, it emits a radially expanding pattern of light that glows briefly in the dark. It is this brief glow that is the point of the universe and the point of life. Chaos theory describes the structures of the paths taken by processes in the universe as they develop from a state of maximum order towards a state of maximum entropy. In Plato, the equivalent to chaos theory is the harmonic theory that the Demiurge draws upon when, having made a mixture of the Same and the Different that includes a notion of space, he divides the mixture up into lengths which are proportionally arranged so that a musically ordered, living universe results. Thus in Plato and in the form of New Platonism here expounded, from out of life there arises the Good and from out of the Good, there arises a notion of God and the ethic that all life is to be cherished and rejoiced in.

Where a sphere is characterised by a single positive curve of +1, its converse is characterised by a single negative curve. This results in something that, were it to be conceived as a solid, would resemble the spinning top were it not for the fact that only not only are the poles and equator are flung out to infinity.

This means that the „solid“ can never be apprehended as such and indeed it is not a solid in any conventional sense and cannot be accurately represented in three-dimensional space. Although counter-intuitive, the notion of such a surface is not illogical or contradictory and within mathematics has even been proven to exist. Moreover it has the capacity to be all-encompassing in ways that spheres and circles never can be. As the poles and equator are at infinite remove, there is and can be nothing that lies beyond the surface and so there is no „outside“ and the surface is all-containing. From this, it follows that there can be only one surface of constant negative curvature. For a second surface, like the first, being all-containing, would have to differ from the first in a way that lay out-with both surfaces, which, as there is no out-with, is impossible. Self-contained, a sphere is defined in a finite and limited fashion so that when fashioned by hand, the making process can interrupted at any stage and resumed later. Equally, neither a half-made sphere, nor a half-drawn circle will ever finish the making or drawing process themselves. In the case of a surface of constant negative curvature, the curve is self-contained in a way that is unlimited and infinite. This means that instead of being contained by the planes of the space with which it is associated, like spheres and circles are, the curve contains the planes with which it is associated. This in turn means that, as soon as a surface of constant negative curvature has been begun, it comes into being all at once. Thus regardless of on which side of the equator such a projection is begun, the surface is engendered on both sides of the sphere’s equator and reaches both up as well as down and round about. This means that it cannot be correctly imported into three-dimensional space or accurately depicted in two dimensions. In this respect the surface can be seen as sharing a number of aspects in common with that which is generally called „God“. Using a system of projection that relates the circle and the sphere to a surface of constant negative curvature, Alexander Curtis has developed a model in which the gradual development of our sense of self from infancy through childhood adolescence and into adulthood is explained and put into context. In this model an axis of good and evil arises automatically in a way that reaches out to the Divine and the conception of the Divine articulated geometrically in this way can be seen as equivalent of Gödel’s Ontological Proof. Moreover the chaos theory that is a characteristic to so much of what takes place within the world is written into the fabric of the all-encompassing surface of constant negative curvature suggesting that this is a genuine and natural instance of reason identifying something that is universal and genuinely of the world as opposed to be being something that is artificially projected onto it. Where π is associated with the circle and sphere and thus with the infinitely far removed equator of a surface of constant negative curvature, the number associated with the actual surface of a surface of constant negative curvature derives from a sequence that reveals something of the nature of the curve. The sequence is a binary number and is generated by taking 0 and 1 and inverting them to make 1 and 0. Tagged on to 01, this makes 0110. This is then inverted and tagged on to 0110, to result in 01101001, which in turn is inverted and tagged on to what has already been arrived at. In this way, an infinite sequence is generated, known as the Morse-Thule sequence and which, converted into decimals results in the Morse-Thule constant 0.412…, which is also a transcendental number. The Morse-Thule sequence is related to a surface of constant negative curvature through the fact that although it is generated through a process of systematic repetition that results in units that can be reconstructed, the way that the units reach out to infinity is not periodic and yet, unlike the sequences that make up π, they are nevertheless in their own and possibly unique way, systematic. This means that by systematically using the units of the sequence, a curve of constant negative curvature can be generated. As found by the mathematician Manfred Schroeder, when period doubling is analysed using a technique of symbolic dynamics, the Morse-Thule sequence emerges. Where the circle can be seen as a metaphor for that which is divine and which lies over and above us, chaos theory is the rationale of that which lies enclosed within the circle. Lying all around us and percolating through us, it forms and moulds, not only us but the substance of the world in which we live.

It being established that similarity and classes of things exist, it follows that the self as defined according to the model worked out by Alexander Curtis, also exists as long as the biological body associated with it is alive and awake. Nevertheless the stuff out of which consciousness is actually „made of“ still remains. When we experience something, whatever we experience is experienced as an experience that is unique to us alone and cannot be directly accessed by anyone else. Although we can share our experieces, this takes place through our using words to indicate what we have experienced. The words we use name things that, we assume, are the same for others as for ourselves. Thus we assume that what someone else experiences as „hot“, is hot and what others see as being red, is the same as what we call „red“. Here again, there is an assumed similarity that is implicit and it is this assumption and the fact that it is only very rarely contradicted that underwrites language and enables us to share our experiences and the nature of our feelings with other people. In this way, we gloss over the fact that for all a physicist may say about the wavelengths of the light that result in „red“ and all a neurologist may say of neurones and firing synapsess, the experience of seeing red cannot be described by science and can only be named by words. With respect to our feelings, the same is also true only the gulf between what is actually felt and the hormones with which science explains our feelings, is more obvious. In both cases, the glossing over takes place as a result of talking about our inner states in exactly the same way as we talk about states of affairs in the outside world. Using the subject/predicate logic already encountered, we assign predicates to objects and subjects indiscriminately. Thus when talking about our inner states, instead of refering to „object x“ we use the word „I“ and then assign a predicate that names what we have experienced or are experiencing. We thus forget that whilst we can talk about our inner feelings and experiences, we can never take them apart and analyse them like a mechanic when confronted with a device whose purpose is unknown but which can be identified through taking apart. In all that is subjective, there is no potential for things to be taken apart, for taking apart destroys that which would be investigated. This being said, the question, „Out of what sort of stuff might our inner experiences be composed of?“ can still be asked and we are allowed to expect an awnser. As the logical objects that reflect the similarity of the world have already been postulated and accepted as existing along with the physical entities that lie behind them, the simplest answer to the question is to say that our conscious experiences are made out of the logical entities that are associated with the physical entities with which consciousness is also associated with, viz. the brain, a body, neurones, et cetera. That thereafter, nothing more can be said is due to the divide that exists between that which is objective and that which is subjective. The explaination is thus restricted to deciding into which ontological catergory of thing the stuff of consciousness is to be thought of as belonging. In this way, whilst associated with states in the brain such as networks of firing synapses, consciousness itself is immaterial and constituted out of the similarities and differences that pertain between the brain and its parts and the brain and the various parts of the body to which it is connected. Whilst this is abstract, it is so by definition and moreover does not involve dogmatically reducing the nature of our inner experiences to purely physical states, as was done for so much of the twentieth century, nor does it involve invoking an otherworldly soul that in a manner that is utterly inexplainable somehow interacts with the physical body with which is it is associated.

Having explained the self and clarified as far as possible out of what it is that the experiences of the self are made, the question of whether the self can in some way survive death remains. While from an atheist point of view, the positions argued for above entail a clear „no“, for the believer and the agnostic, the matter is more complex and involves Plato’s notoriously difficult dialogue *Parmenides. *Following an analysis by Alexander Curtis this brings the investigation back to Russell’s paradox and the consequences of statements that refer to themselves. Here the writings of the Renaissance philosopher/theologian Marsilo Ficino (1433-1499) provide something that one might dub as a theological prelude to Russell’s Theory of Types. As one would expect, this involves faith and once again necessitates moving over from philosophy to theology. Praise be to God!
