David Deutsch on Proofs - Dictionary of Arguments
I 211 Experiment/proof/tradition: A proof does not refer to the physical world. (DeutschVsTradition: this is wrong.) We can perform a proof in our head, or even when we are stuck in a reality simulator in which virtual reality false physics applies. >Simulation, >Reality, >Provability. I 212 Traditional idea: Certain abstract sizes are not only part of the reality, but even more real than the things of the physical world. >Mathematical entities, >Abstract objects, >Theoretical terms, >Reality. I 237f Proof/David Deutsch: A proof is a physical process. - In contrast to this: size and knowledge of this size. >Description levels, >Levels/order, >Knowledge. Theory: the aim of a theory: not certainty but explanation. Physics is totally understandable. >Physics, >Explanation. Mathematical intuition is incompatible with classical physics. >Quantum Theory._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
