Augustine set out to understand, by analogy to his human mind, what went on in God to create the Trinity. This work created a line of research in theology which extends to the present
[page 264]
day and our purpose is to apply his ideas to our model of god, naked gravitation, and our formal means is the mathematical theory of fixed points, first developed by Bertus Brouwer and extended by the Katukani fixed point theorem. Here also it is appropriate to ask [how does mathematics play a role in physics]. Brouwer fixed point theorem - Wikipedia, Kakutani fixed-point theorem - Wikipedia

Hartle on geometry and metric - describing space by the inner product, Euclid, Minkowski, Einstein, von Neumann. James Hartle (2003): Gravity: An Introduction to Einstein's General Relativity
Trying to get the cognitive cosmogenesis essay going by skipping a lot of detail.
Symmetry with respect to complexity connects my childish love of orgasm with my adult search for understanding, relativity, covariance rooted in God
[page 265]
who is automatically covariant because unique and remains unique because everything is created within god via fixed point theory, bootstrapping itself from an empty set until now. The first thing to come is time which distinguishes bosons [which exist outside time] from fermions [which are massive, living in time, static energy, there is zero sum bifurcation somewhere in the generation of fermions and bosons, perhaps in fermions, which comprise both timeless energy/action, little bits of naked gravitation and exist as units which travel in spacetime subject to Lorentz transformation - Minkowski metric]. The essence of it all is something that flashed through my head and disappeared, a property of Hilbert space, the duality of hermitian operators leading to [static] real diagonals(?) [ie selecting consistent stable superpositions out of the creative variety of the random Hilbert interior of the initial singularity]. Now banana and cornflakes.
The Trinity is done.
The next question is the role of mathematics in physics and the best dichotomy seems to be between puppets and movies and living systems that can move themselves from bottom up substances, combinations of essence (form) and existence. Perhaps we can redeem Aristotle's distinction between energeia (activity, energy, [time] frequency of quanta of action, life) and entelecheia (activity) Does not seem to work well. Puppet (form, plan), substsance (reality). A difficult thing to find words for form and activity, where by activity we mean the execution of quanta of action [ie energy].
Is there arithmetic in a can of beans: Cantor says yes. We are talking about mind in matter.
Does God laugh? Does quantum mechanics?[page 266]
I can only do what I can do. What I want is another interpretation of linearity vs quadratic. What we want to know is how the Minkowski metric turns linear quantum mechanics into quadratic metric. This really is the heart of the plan. We get from quantum mechanics to the Minkowski metric with massless bosons on the null geodesic and the exclusion principle [which creates the 3D Euclidean domain] of the fermions. The way to seal this deal is to produce the necessary operators to produce bosons and fermions and my guess is an overtone one octave above a base note. The question then becomes why are fermions massive, how is all this energy held together in an electron? Here is what we used to all the pons asinorum, but if the particles really give us the correct metric we have the space and the properties of spacetime built into the metric, which we just have to demonstrate.
The critical issue is to make a story that fits the facts but this is where the mathematics comes in since if it is provable it is a consistent system that has a chance of fitting a natural system that has been shaped by consistency [through natural selection]. So we go fixed points / basis states ; kinematics / stationary points. Our model of quantum mechanics (simple version) is music, complex version is speech.
[page 267]
The concept of cognitive cosmogenesis brings in Augustine's idea of the mental image of the outside world (the quantum image of the Minkowski world) which can embrace both syntax and image in a form which is differentiated in spacetime. In quantum mechanics we have a density matrix of vectors and values which may be ordered into different syntaxes in Minkowski space. Here we touch on Sirridge's point of holistic image versus sequential syntax, Augustine's static mind of god versus the moving syntactic ordered mind of man. A Turing machine works by sequential steps; a quantum machine works by superposition of vectors / symbols like a source dealing with its whole alphabet at once. Mary Sirridge (1999): Quam videndo intus dicimus: Seeing and Saying in De Trinitate XV
We have misunderstood quantum mechanics by trying to map it onto Minkowski space without explaining the particulate degree of freedom that exists between them [ie quantum mechanics pixellates Minkowski space with elementary paricles].
The Sirridge Augustine point emphasizes that our minds work by linear superposition modulated by synaptic weights since the neuron itself is a single space responding linearly to the input it receives at the 'inside' of its interfaces with the synapses.

The idea the information is physical begins with the divine and physical reality of naked gravitation, essence ≡ existence, ie eternal since its essence is to exist, we might call this the fundamental tautology.
Anti-theocracy, anti-genocide. God did not create mankind, mankind created God in their own image, and most of the gods are genocidal autocrats exterminating the indigenous inhabitants of their promised lands.
A happy morning due to Landauer. We reject the notion what spirituality is the source of intelligence and require that all forms have a material basis, but also hold that the realization of form, ie a mathematical symbolic entity, is dependent upon its consistency because if it is energized [ie put into action] and there is inconsistency present it will blow up / fail [as a misapprehension while driving in traffic can lead to a collision].
Augustine's approach to the realization of the Son in the mind of the Father provides us with a model for the fixed point theoretical appearance of Hilbert space and quantum mechanics in the mind of God. We have seen a number of tours de force in [microscopic] neuroanatomy lately that suggest that brains work by a form of hard wired linear superposition which has non-linearity built in to the influence of each synapse on th linear integral realized by a neuron as it reaches is firing point. Carissa Wong (2024): Cubic millimetre of brain mapped in spectacular detail

There ought to be an insight here for the designers of artificial intelligence.
Did I have post-monastic trauma? Certainly my Catholic upbringing had given me a seriously twisted view of women and sex and my last few years at school were characterized by an avoidance of women to preserve my intention to enter a life of chastity at the same time as I was embroiled in the irresistible 'evil' of masturbation, which I now see as a dying echo of the desire to reproduce [the lust for life] ingrained in me by evolution. It is only now that I am nearly 80 that I can contemplate having an understanding relationship with a woman, a bit too late to start again but inspiring my efforts to conquer the theocratic genocide that infects all traditional divinities.
It is exciting little days like this that keep me going. I love naked gravitation. It is divine.
Minkowski space is pixellated by quantum mechanics and these pixels correspond to fundamental particles just as an apparently continuous beach is pixellated by grains of sand.
In a divine universe theology and physics have the same subject and so they can help one another.
What am I waiting for? Watching football.
[page 270]
A hint of motivation. The Son of God ≡ Hilbert space in naked gravitation.
Here comes the bit about continuous mathematics cannot be supported by rational substance [the material foundation must coincide to the form represented, as in Aristotle's hylomorphism; this may be why the field theorists need renormalization, since the Euclidean element of Minkowski space, created by the fermionic exclusion process, may not be geometrically continuous].
Logical continuity is the natural state of Hilbert space because from a formal point of view it is outside [physical] space, time and distance. We may see it as in effect a de facto null geodesic and we see this represented in the property of Minkowski space when it comes to be. The property of bosons, massless and travelling at the speed of light, may be seen as a cause of null geodesics, rather than as a consequence, a form of Hilbert space formally embedded in Minkowski space. We see naked gravitation as neither form nor energy but substance, ουσια, reality. We have to sort all this out in the passage "is there arithmeic in a bag of beans?"

We imagine the first steps in the creation of the world by analogy with Augustine's model of the creation of the Trinity and we bring it to light by contrasting two approaches to the philosophy of mathematics, Platonism and Formalism. Platonism imagines that the forms of mathematics are as real as beans. They are not created but
[page 271]
discovered. This could be true in the current world but could not be true in the initial singularity because there is no structure there. The alternative is Hilbert's formalism, imagining mathematics in the current era as a creation of human minds, a symbolic game bounded only by consistency. The rules of consistency are the logical principles stated by Whitehead and Russell. Whitehead and Russell (1910): Principia Mathematica
So let us now go into the interior of naked gravitation and apply the formalist approach to creating the Universe. In Augustine's day we might have imagined the initial singularity, naked gravitation, the God of Aquinas, as Plato'a form of the Good. The West was not yet aware of the work of Aristotle. We apply Brouwer's fixed point theorem, imaging that the functions mapping the initial singularity onto itself, for arguments sake, are Turing computable, ie there are a countably infinite set of then, creating a countably infinite set of fixed points which we imagine to be the basis states of an abstract Hilbert space specified by von Neumann. The basis states we take to be real in the Platonic sense, their reality supported by the reality of naked gravitation in the same way as the reality of the Son of God is supported by the reality of the Father. Here we can turn aside for a moment to discuss the mathematical problem Einstein introduced into field theory.
[page 272]
We might say that the work of nineteenth century mathematicians was to make the Euclidean portion of Minkowski space tractable [for] calculus using the method discovered by Fourier to represent functions by trigonometric series. . . . since the beauty of trigonometric functions derived from the application of complex numbers is that they are perfectly differentiable and integrable. Cantor was involved in this work, but it was beset by contradictions which he resolved by replacing the ever smaller infinitesimals necessary to make calculus work by ever increasing transfinite numbers which seemed logically sound, particularly to Hilbert, the creator of formalism. Einstein's application of electrodynamics, simplified by Minkowski, led to the mystical statement
105 km = √-1 seconds
The scene was set for logic to take over from [the] Pythagorean metric and quantum mechanics to enter the scene as the first creation of the mind of God. Albert Einstein (1923): The Principle of Relativity - A collection of original memoirs on the special and general theory of Relativity. With notes by A. Sommerfeld. Translated by W. Perrett and G. B. Jeffery, page 88
Our best approach to an approximation of Hilbert space is our taste for music and the explosion of new sounds that have entered modern music are the result of the invention of synthesizers and analyzers that apply versions of Hilbert space to sound via Fourier analysis, but we need not go into this here. Instead we remain abstract and explore the linear structure and computational power of quantum mechanics understood as a theory of computation and communication, remembering
[page 273]
that an error free transmission of data is a computation in spacetime whose output is identical to its input.
This, then, is the program for cognitive cosmogenesis.
Quantum mehanics cuts the cosmological constant down to size by selecting [stable] consistent structures out of the imaginary chaos of uncertainty that pundits of field theory like Wilczek have created out of quantum "unertainty" and "fluctuations". The problem is succinctly described by Hobson, Efstathiou, & Lasenby:
How can we calculate the energy density of the vacuum? . . . The simplest calculation involves summing the quantum mechanical zero point energies of all the fields known in Nature. This gives an answer about 120 orders of magnitude higher than the upper limits on Λ set by cosmological observations. This is probably the worst theoretical prediction in the history of physics!Frank Wilczek (2008): The Lightness of Being: Mass, Ether, and the Unification of Forces, Hobson, Efstathiou &. Lasenby (2006): General Relativity: An Introduction for Physicists, page 187.
My essay might be judged to manifest an excess of speculation but I do not think it is much weirder than the history of salvation proposed by the Roman Catholic Church or the mechanism of the world proposed by quantum field theorists whose computations differ from reality by a hundred of orders of magnitude. One may imagine that the role of superposition modelled by linear quantum operators in fact quells the enormous variety of the random fluctuations of the world, giving us the stable structures that we now see. The tricky bit is going from the kinematic variety of the creation of random vectors in Hilbert space to the steady realization of fundamental particles by the zero sum bifurcation of naked gravitation into potential and kinetic energy to give reality to formal structures.

Quantum mechanics and football, players moving at random and coupled by passing.
What is my theological take on quantum mechanics?
My specific interpretation of quantum mechanics is a) the quantum of action is a logical operator; b) every fundamental quantum event at the elementary level involves precisely one quantum of action. The flip of spin requires 2 x ½, the absorption or emission of a photon involves 1. The stationary point in Hamilton's method is exactly 1 quantum, as [it] is in Feynman's path integral. The photon is massless and outside time. The fermions are massive and we do not know how they stay together. What is electric charge? Is the integrity of the electron related to the integrity if the proton and so on. Hamilton's principle - Wikipedia, Path integral formulation - Wikipedia

We watch the bodies moving and imagine the feelings that they are experiencing based on our own experience. From this and the principle of symmetry with respect to complexity we seek an understanding of quantum mechanics

Electrons and protons communicate through photons. How do we set this up in quantum mechanics? Via spin and energy. Jennan Ismael (Standord Encyclopedia of Philosophy): Quantum Mechanics
Type = state independent + state = physical quantity = observable ,
State spaces of quantum mechanics are Hilbert spaces which have more internal structure than their classical counterparts.
A model is a mathematical structure to represent some physically signifiant structure in the world.
* ' know your way around Hilbert space and become familiar with the dynamic laws that describe the paths that vectors travel through it, and you know everything there is to know, in the terms provided by the theory, about the system that it describes.'
Jeffrey's theorem: There is no energy and no momentum and no hamiltonian in quantum theory. These are attributes of Minkowski space after quantum fixed points become realized by energy derived from the bifurcation of naked gravitation.
[page 276]
Dirac could not find a Hamiltonian because there is no Hamiltonian in quantum mechanics, which predates Minkowski space. This is a substantial breakthrough and will provide a new light on the power of linear quantum mechanics to derive stable structures from the random creation of Hilbert space inside naked gravitation, a sort of chaotic trinity stabilized by linear superposition.
Tomorrow we bury Andrew, over the weekend try to write this week up.
The rules of renormalization give surprisingly, excessively good agreement with experiments. Most physicists say that these working rules are, therefore, correct. I feel that that is not an adequate reason. Just because the results happen to be in agreement with observation does not prove one's theory is correct. . . . I have spent many years searching for a Hamiltonian to bring into the theory and have not yet found it. I shall continue to work on it as long as he can, and other people I hope will follow along such lines [perhaps another Einstein dead end!]. Peter Goddard (1998), ed. Paul Dirac, The Man and His work, page 28
We are happy that the Schrödinger equation describes deterministically the evolution of vectors in Hilbert space if we assume the determinism of complex functions and differential operators, but is this real? We cannot tell. In a way it is analogous to general relativity in Riemann's differentiable manifold. Differentiable manifold - Wikipedia
The other feature of quantum mechanics is observation which means that the continuous evolution of the Schrödinger equation is interrupted by contact with another system and the system evolves in the tensor product if the two spaces involved and we observe an eigenvalue of an eigenvector in the product space. This at least seems to be Zurek's description which I have tried to understand, accept and quote. Wojciech Hubert Zurek (2008): Quantum origin of quantum jumps: breaking of unitary symmetry induced by information transfer and the transition from quantum to classical
Now we turn to Ismael's description of the process and its interpretation.
[page 277]
Trying to recover a short quantum mechanical synthesis of the Cognitive Cosmogenesis book, rather like the summary in Lust for life: index. What I am really looking for is a fact check, via Ismael, and I should make myself do it. Jeffrey Nicholls (2025): Cognitive Cosmogenesis: A systematic integration of Physics and Theology
* [from p 275] We say that the kinematics of the creation and annihilation of Hilbert space in naked gravitation is outside space and time but has a formal component which may be similar to the fluctuations imagined by the promoters of quantum uncertainty. There are no routes, just a formal axiomatic structure as defined by von Neumann which must be realized in some way because information is physical, ie Hilbert space as actualized is a form of naked gravitation which is a real substance but as yet [without] mass, energy and potential. We have to be very careful about what we are saying here. John von Neumann (2018): Mathematical Foundations of Quantum Mechanics, chapter 2

Maybe prefer Feynman's account to Ismael.
Feynman III_08, equation 8.9;

〈χ|ψ〉 = Σall i 〈χ|ψ〉
Wave equation / amplitude - turn the amplitude (volume) up to 11, beyond renormalization.
Any state vector can be represented as a superposition of "unit vectors" in suitable proportions. [and the relative proportion of these vectors depends on their relative phase, so we can imagine given enough randomly created basic unit vectors in naked gravitation every now and then the superposition will yield a stable state.] If this superposition of unit vectors of "noise" represents a stable state, we have grounds for the conversion of this state by zero-sum bifurcation of gravitation into a real particle, either fermion or boson. This is how we deal with random fluctuations.
[page 279]
1. We consider it an open question whether any element of reality other than naked gravitation (or the structureless God) is continuous and therefore a proper subject for differential and integral calculus.
Feynman wave vs particle viewpoints
1. Wave Schrödinger equation fixed deterministic evolution and unitary, ie it is an automorphism, preserving inner product and linear space.
2. Measurement context - collapse postulate and Born Rule.
Which contexts are measurement contexts - all particle interactions /conversations are between persons. Have said this again and again and sometimes a new bit of meaning seeps in. This is scale invariant.
'All the physical consequences of the behaviour of quantum mechanical systems are consequences of the mathematical properties of these relations. Or is it vice versa, mathematics is implicit in physics. So what it is about physics? [It works, or not if we get it wrong. Research is quick; development is tedious because it has to be got right]
P(1): operations on vectors yield vectors, ie the system is closed [like a group]. Normalized unit vector represents pure state (but it can be the normalized sum of any number of constituent vectors). Measurement of observable B on state |A〉 collapses the system into B eigenstate corresponding to eigenvalue observed with Born rule probabilities.
P(2) many hermitian operators on same space partly or fully disjunct extracting diferent results.
[page 280]
† 'Anyone trying to come to an understanding about what quantum mechanics says about the world has to grapple with one remaining fact: Dynamic problem, rules that describe the trajectories that systems follow through space and time - points to logical inconsistency, or maybe a degree of freedom since there is no space and time in Hilbert space and quantum mechanics, as I repeat endlessly to myself. So Jennan states 'the measurement problem'. Tomorrow formulate the answer.

the point about measurement is that there are as many answers as the eigenvalues of the measurement operator.
Physical state is a unit vector, ie a quantum, and fixed point theory guarantees the random creation of such states in naked gravitation which is in effect kinematic motion that can be represented by wave and phase. All vector operations are superpositions governed by relative phase, so amounting to varying degrees of addition and subtraction.
What is the quantum theoretical analogue of mood? Phase?
.Ismael 3.4 (a): 'All our knowledge of unobserved dynamics is based on the mathematics of the Schrödinger equation, deterministic, unitary, ie closed and energy conserving, and linear, ie all operations are superpositions [and may be totally irrelevant, another result of classical prejudice].
[page 281]
The outcome we want most is that the evolution of quantum mechanics works like the agent intellect, solving intellectual problems [bringing order out of chaos by phased superposition], but is this possible for a deterministic system [NO, so if Schrödinger has any role, it is in the realm of quantum statistics, which is deterministic Alexandr Khinchin (1960, 1998): The Mathematical Foundations of Quantum Statistics]. Christopher Shields (Stanford Encyclopedia of Philosophy b): The Active Mind of De Anima III 5
So we turn to Ismael 3.4 (b) "measurement" uncertainty and paradox. 'Carrying out a "measurement" of an observable B on system in a state |A〉 has the effect of collapsing the system [|A〉 ?] into a B eigenstate corresponding to the eigenvalue observed. '. . . the Collapse Postulate → Born Rule [which is a bit like the controlling idea that people can only say one word to eachother, no conversations ranging over the whole density matrix allowed. But this may happen outside the laboratory.]
' The distinction between contexts of type 1 [3.4(a)] and 2 [3.4(b)] remains to be made out in quantum mechanical terms.' In fact it seems pretty clear from the independence of quantum theory and entanglement that there are no isolated tye 1 systems see : page 13: Is Hilbert space independent of Minkowski space?.
'It is an open interpretative question whether there are any contexts in which systems are governed by a dynamical rule other than the Schrödinger [deterministic] equation, so where does the Born rule come in?
My problem is that there are so many details like this that cannot be included in the Cognitive Cosmogenesis [article] without making is too long so they have to be subsumed in more general statements which are true [ie a total rewrite of quantum mechanics from naked gravitation on up].
The thing is that a Hermitian operator yields a density matrix of outcomes at each operation [which amounts to a record of a conversation between two particles, since all meetings of particles are in fact measurements: as soon as I see you I begin measuring you before we have said a word: eyes. face, hair, clothes, movement; there is no second chance for a first impression].
[page 282]
Khinchin Chapter 2.1: 'In classical mechanics the state of a system can be represented in a Euclidean phase space of 2s dimensions representing all the Hamiltonian variables pi, qi. Each physical quantity is a F(pi, qi) of the Hamiltonian variables with definite values for each definite state. QM is different - state described by complex function U(qi). Knowledge of U does not make it possible to determine the Hamiltonian variables pi, qi. This seems to be an entropy question, quantum entropy greater than classical.
In QM classical pi and qi cannot have definite values for any given i (in Minkowski space where uncertainty is held to rule, U determines a distribution law for qi, not their values).
The probability is integral over subspace |U|2 dqi divided by integral over whole space of |U|2 dqi. Elementary particle hamiltonian x, y, z, px, py, pz probability of position determined by equation above.
The foundation of quantum statistics [requires that] each of the systems must be in the state U at the moment of measurement. All that is necessary is that the system be brought to the state U before the following measurement is made. 'The fact that the statistical predictions of quantum mechanics are independent of all supplementary conditions is one of the most important general principles of the theory and gives the predictions real statistical meaning.
[page 283]
Khinchin 2.2: Physical quantities and self-adjoint linear operators.
Self adjoint operators connect measurements taken on the general quantum coordinates qi to the classical hamiltonian variables pi and qi. See † page 280. Measurement problem. - Back to Ismael section 4:
S* measures observable A on S, values a1, a2, a3. There is some state of S* [therefore also a quantum system] a ground state and some observable B pertaining to S with values b1, b2, b3 (called a pointer observable, pointing to states of S*). What we mean when we say S* measures A if A = a1, B = b1 and so on.
So we say dynamical law says
|A = ai〉S | B = ground state〉S* → |A = ai〉S | B = Bi〉S*
Intuitigely S* is a measuring instrument for an observable a just in the case there is some observable featue=re of S* (no matter what. we can see it) which is correlated with the A-values of systems fed into it in such a way as we can read off S*'s observable state after the interaction. S* is a measuring instrument for A when some observable feature of it tracks or indicates the A-values of the system with which it interacts.
Feynman III_03: Here he is talking about particles going through a space but in fact there is no space in Hilbert space and what we are really talking about is one state becoming another and our first job is to find out how a Hilbert space with a random basis can form fermions and bosons.
[page 285]
One approach is to assume that in pure quantum mechanics with computing power exceeding Turing this happens somehow, the new states get energy from gravitation and off we go creating Minkowski space but it would be nice to get an operator on Hilbert space which yielded the 'forms' of bosons and fermions. How do we get the old head around this? [What would the waveform of an electron sound like?] Quantum field theory assumes the existence of electron fields and boson fields. Ask Google.
Led me to C. G. Torre Charles Torre (2018_06_16): What is a Photon? Foundations of Quantum Field Theory
Torre page 11: ' Self-adjoint operators are used because their (generalized) eigenvalues form a basis for Hilbert space.
Time evolution defined by |φ(t)〉 defined by Hamiltonian. Good, but there is no space and time in Hilbert space? Time is represented by random fixed point activity in naked gravitation [which might finish up a something like a kinematic (energy free) ladder operator imitating a clock setting the irreversible time for the Universe as the first form to appear in naked gravitation].
The splitting between a quantum system and its classical environment means measuring the observable A by a measuring device in the environment with outcome a leaves the quantum system in the state |a〉. Both measured system and measuring system are classical particles.

Skip a few pages
page 106: Normally the (classical) spacetime geometry is used to build and interpret quantum field theory so it becomes problematic to construct a quantum field theory of spacetime itself. The challenges inherent in devising a quantum description of the gravitational interaction represent, in many ways, the principal problem of theoretical physics. Without some compelling guidance from experiment it is likely to remain an open problem for some time to come. The 'experiment' is human theological (ie spiritual) experience. Goodnight.
What did I learn from this? Perhaps
[page 286]
quantum mechanics is belittled and corrupted by being mapped onto Minkowski space, So we purify it by connecting it to god, and the noise in god from which the self-adjoint operators select perfection, a product of normalization and quantization. The central point is that the quantum is a logical operation [and since, perhaps, the fixed point process preserves normalization all quanta of action are at root representations of god and we feel their action in naked gravitation. At the limit, the whole Universe is one quantum of action descended from the one primordial quantum of action by internal complexification. Now afternoon rest and then the journey continues.].
