John Archibald Wheeler: “it from bit” Every “it”— every particle, every field of force, even the space-time continuum itself derives its function, its meaning, its very existence entirely—even if in some contexts indirectly—from the apparatus-elicited answers to yes-or-no questions, binary choices, bits. “It from bit” symbolizes the idea that every item of the physical world has a bottom—a very deep bottom, in most instances, an immaterial source and explanation, that which we call reality arises in the last analysis from the posing of yes-no questions and the registering of equipment—evoked responses, in short all matter and all things physical are information-theoretic in origin and this is a participatory universe.

I regard consciousness as fundamental. I regard matter as a derivative of consciousness. We cannot get behind consciousness. Everything that we talk about, everything that we regard as existing postulates consciousness.
As a man who has devoted his whole life to the most clear headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind. This mind is the matrix of all matter. – Das Wesen der Materie [The Nature of Matter], speech at Florence, Italy (1944) (from Archiv zur Geschichte der Max-Planck-Gesellschaft, Abt. Va, Rep. 11 Planck, Nr. 1797)

The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve. – “The Unreasonable Effectiveness “The Unreasonable Effectiveness of Mathematics in the Natural Sciences,” in Communications in Pure and Applied Mathematics, vol. 13, No. I (February 1960).

Curious that, for real, hardtack physical materialism, you have to find a philosopher or psychologist who is into neuro-nut moments or evo psych, not a great physicist.
