6 ideas

26. Natural Theory / A. Speculations on Nature / 4. Mathematical Nature
Everything must involve numbers, or it couldn't be thought about or known [Philolaus]
     Full Idea: Everything which is known has number, because otherwise it is impossible for anything to be the object of thought or knowledge.
     From: Philolaus (On the Cosmos (lost) [c.435 BCE], B04), quoted by John Stobaeus - Anthology 1.21.7b
Harmony must pre-exist the cosmos, to bring the dissimilar sources together [Philolaus]
     Full Idea: It would have been impossible for the dissimilar and incompatible sources to have been made into an orderly universe unless harmony had been present in some form or other.
     From: Philolaus (On the Cosmos (lost) [c.435 BCE], B06), quoted by John Stobaeus - Anthology 1.21.7d
There is no falsehood in harmony and number, only in irrational things [Philolaus]
     Full Idea: The nature of number and harmony admits of no falsehood; for this is unrelated to them. Falsehood and envy belong to the nature of the Unlimited and the Unintelligent and the Irrational.
     From: Philolaus (On the Cosmos (lost) [c.435 BCE], B11), quoted by (who?) - where?
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / d. The unlimited
Existing things, and hence the Cosmos, are a mixture of the Limited and the Unlimited [Philolaus]
     Full Idea: Since it is plain that existing things are neither wholly from the Limiting, nor wholly from the Unlimited, clearly the cosmos and its contents were fitted together from both the Limiting and the Unlimited.
     From: Philolaus (On the Cosmos (lost) [c.435 BCE], B02), quoted by John Stobaeus - Anthology 1.21.7a
26. Natural Theory / D. Laws of Nature / 6. Laws as Numerical
Self-created numbers make the universe stable [Philolaus]
     Full Idea: Number is the ruling and self-created bond which maintains the everlasting stability of the contents of the universe.
     From: Philolaus (On the Cosmos (lost) [c.435 BCE], B23), quoted by (who?) - where?
The laws of number are not laws of nature, but are laws of the laws of nature [Frege]
     Full Idea: The laws of number are not applicable to external things, and are not laws of nature, but they are applicable to judgements of external things: they are laws of the laws of nature.
     From: Gottlob Frege (Grundlagen der Arithmetik (Foundations) [1884], §87)
     A reaction: We seem to be somewhere between pythagoreanism and 'the mind of God'. I feel fairly strongly that we are looking through the wrong end of the telescope here. The laws of nature 'emerge' from nature, and high-level abstractions emerge with them.
