The Autho deals with completeness and consistency and frames mathematics outside the formalist paradigm, which I've already said a few times now.SanteriSatama wrote: ↑Mon Jul 12, 2021 12:59 pmIn the quote "substance" is explained by other meanings, which can be further looked upon in a dictionary where words are explained by other words. Reading a dictionary, meaning arises from how dictionary entries relate to each other. The above is an attempt to prove "substance" by assumed absurdity of "infinite regress". Potentially infinite regress, however is not a problem, as completeness is not necessitatated nor assumed beyond axiom of reductionism. And with axiom of reductionism, say hello to Gödel's incompleteness theorem.Squidgers wrote: ↑Mon Jul 12, 2021 11:55 am Were there no substance, then nothing could be explained in terms of anything. Without substance, when we explain something, then we would always need recourse to another thing, and for that thing, another as well, and so on ad infinitum. Further, if we were to stop explaining a thing in terms of another thing at some point without positing a substance, then there would be no sufficient reason for one cut-off point rather than another, hence explanation in this context is either infinite regress or no explanation at all."
Only actually infinite regress of "completed infinity" (such as real numbers) is a genuine problem and absurdity, but nothing a priori necessitates such absurdity, as axiom of reductionism is totally arbitrary metaphysical choice.
"Flowing points", what ever that is supposed to mean, substantial or not (and I'm genuinely curious), at least refers to motion. In the standard canon of Western philosophy, as exemplified e.g. by Kant, substance is supposed to be diachronically permanent, temporally immutable. I'm guessing, but the argument of the book seems to fall into the category of mathematical platonism, immutable and eternal Platonia as the "substance"?
Problem with immutable Platonia is that as historical phenomenon, mathematical languages and thinking have been changing and evolving, and there are passionate foundational disputes between various philosophies and perspectives. Empirically, mathematics is not only found, but also created evolutionary process.
Gödel's incompleteness theorem is just a specific case of the more general Halting problem, as Chaitin explains
"Eidomorphism as a panpsychism is compatible with both immaterialism and physicalism. This may seem like an outright contradiction at worst or a paradox at best, but in actuality, this follows quite logically from the way the properties of the fundamental substance have been outlined. Given that matter is something unexperienced which is finitely divisible, beyond which there is only void, it follows from two directions — both Sprigge’s arguments and from substantial forms — that matter as the fundamental substance does not exist. Hence, the fundamental substance is by definition immaterial.
Yet, if we think of physicalism only in terms of there being extended entities with ‘physical’ properties — that is, predictable, deterministic, having ‘mass’, etc. — then physicalism can be conceived in terms of eidomorphism as well. Indeed, mass, determinism, predictability, and any other ‘physical’ can all be conceived in terms of mathematico-metaphysical points in motion against a continuum of points, whereby the trajectories of these points conform to mathematical laws. The world of eidomorphism is not an airy dreamworld per se, but rather it consists of real things either in extension or being unextended. Space and time are emanations of the Singularity, and all phenomena are emanations of the Singularity and result out of the basic properties of the Singularity.
Thus, we may also call eidomorphism a mathematical monism or even mathematical idealism because of the ideal property of experience being embedded in a mathematical substance. Even in idealism, mathematics is something invariant in our perceptions, and also what is invariant in our phenomenal experience and invariant in reasoning. As we can see, even in idealism mathematics would be what intellectually describes or even maintains the stability of the world and what guarantees the world’s intelligibility in exact terms."
There is a large section on the description and definition of what ontological mathematics is (the author calls it 'eidetic mathematics' later), but here is a small sample from the section Abductive Proof of Complex Numbers as the Natural Mathematics of Ontology
"The following proof is an abductive proof for lack of a strictly deductive one, though the constraining principles in use eliminate any doubt as to why one explanation will be better than another. We begin by invoking the Principle of Mathematical Completeness, and so it follows that whatever mathematics we must consider to be inherent in the structure of the fundamental substance, it must be a mathematics that is invariant in form under any mathematical operation. To clarify what we are asking, we are considering exactly which number system is the one that has the best chance of being ontological. To answer this question, we need to rule out any alternatives, leaving us with the one and only option. Hence, we are performing a proof by elimination. We can be thankful that given our rather constrained requirements, the proof may be performed in a fairly brief manner since few number systems fit our requirements.
The algebraic analogue to the Principle of Mathematical Completeness is algebraic closure, whereby a field of numbers is closed under all defined operations. A proof of algebraic closure is unnecessary here, but even those slightly familiar with mathematical literature need only look to the Fundamental Theorem of Algebra to understand why the complex numbers form an algebraically closed field.
Our reasoning proceeds thus: no mathematical operation is privileged over another, hence all mathematical operations are ontologically allowed. As inherent forms describing the contingent combinations of modes, mathematical operations are ontological operations, and so the number system inherent to ontology must be able to survive all possible operations. The positive numbers are immediately excluded because they are not closed under subtraction; the integers are also excluded because they aren’t closed under division (excluding zero); the rational numbers are excluded because they cannot take into account algebraic and transcendental numbers (hence cannot perform certain algebraic operations and infinite series); and the real numbers are also excluded because they are not closed under the roots of negative numbers. However, hypercomplex numbers, quaternions, octonions, sedenions, etc. are all types of numbers that cannot perform all algebraic operations, even though they are generalizations of real and complex numbers as well. The sweet spot rests with the complex numbers, namely the projective complex plane, since the projective complex plane also allows for division by zero because there is no sufficient reason to exclude any number from our reasoning.
An additional a posteriori argument for the complex numbers as being the fundamental number system in ontology is seen by simply considering the explanatory success of complex numbers in the fundamental sciences. Complex spaces and the complex projective plane are indispensable to quantum mechanics and all its subsets, such as quantum electrodynamics and chromodynamics. The complex numbers are also found in gauge theory, the unitary groups of the Standard Model, and also the quantum wavefunction. The assurance of their ontological basis is to be found simply in the ubiquity and indispensability of the complex numbers in the fundamental sciences and all of the derivative special sciences as well."
And a section describing how it differs from platonism called The Problem With Platonism and Realism.
"Platonism and realism about mathematics both admit that mathematics is a real, mind-independent structure. The difference between the two is that platonism admits a transcendent and abstract realm independent of matter, space, and time, while mathematical realism is a more general position admitting to the reality of mathematical objects either grounded in matter or some other substance. With realism, there may be a number of different positions regarding what is ontological, and either some or all of our human-derived mathematics is a direct consequence of whatever is ontological. Technically speaking, eidomorphism is a type of mathematical realism that is an expression of an immaterialist but non-platonist neutral monism. For mathematical platonism, there is the dualism of abstract and concrete, and the inherent problem of how the two ever interact. For realism, the problem is that no exact definitions are given for ‘structure’, for matter or a neutral substance, and also the alternatives have not been ruled out. Eidomorphism deliberately avoids grounding mathematics either in pure abstraction or some poorly-defined ontological structure inherent to matter, given the problems with both positions.
Philosophy’s problems with mathematical realism are overdetermined in that there are too many positions which say that mathematics is real, while platonism is underdetermined because it doesn’t account for all phenomena and indeed cannot even account for the concrete-abstract distinction itself. When we talk of realism, if what we consider ‘real’ is something that is independent of our own subjective preferences and what can be accessible to multiple people using an agreed-upon methodology, then we realize that ‘real’ is indeed overdetermined and multiple metaphysical theories will say that certain entities are real, even though such entities may be incommensurable when we compare them to each other. It is at this impasse that philosophy and science have floundered and thus rejected metaphysics. However, if we are asking what is logically necessary and possible, and if we rule out even vanishingly small possibilities that generate absurdities, then we are on the metaphysically correct track to talk of explanatory necessity and ontological necessity.
With eidetic mathematics, when we think in terms of numbers and relate to ontology in terms of numbers, then we are directly experiencing the noumenon and we can directly understand all of existence. When we reason mathematically, there is no reality that becomes mediated by manmade language. Eidetic mathematics grounds numbers on relationships between flowing points, and these relationships may define numbers in terms of ratios of frequencies to frequencies, amplitudes to amplitudes, or even clusters of flowing points to each other. There is, for instance, the open question as to what is the natural base system for mathematical ontology. Thus far, there is no a priori proof of what exactly is the natural, though it’s an open possibility, and we’ll refer to it from here on as ‘base-X’. There is no ambiguity in eidetic mathematics: numbers are concrete relationships between flowing points, whose structure is inherent in an explanatorily necessary, self-perpetuating, self-contained, self-consistent, and analytic ontology."
