I started studying maths for the sake of Truth. And at that time it was the nearest thing to the Truth for me. After studying five years Maths degree in Spain (don't know the equivalent in England or USA) I ended a little bit dissapointed. From my point of view we are far away from knowing mathematics. For expample, we don't kwnow what are numbers... we just made up a construction in set theory to be able to justify the known maths, and it works wonderfully, but... we still don't know what numbers are.
Anyway... I love maths and they are an infinite and fascinating universe.
