I think he likes math because it's consistent. E.g. if I prove that some natural number "x" is prime in decimal, then "x" is also prime in binary, ternary, octal, etc. Counting "x" in a different base doesn't change the symmetry. Likewise, arriving at a theorem via different proofs just describe the same mathematical object in different ways.
