The present is the past biting into the future.
When Arthur Ashe plays tennis, his purpose each day is to play the game in a way he has never played it before. It may be a backhand he uses, one that he may never have used before in that circumstance. His play is a fresh integration of his world at the instant of action. A really great scientist has the whole past at his disposal. At any instant he is rebuilding the world, molecule by molecule, in his subconscious. That is what you want in an athlete or a scientist.
The role of science is to be systematic, to be accurate, to be orderly, but it certainly is not to imply that the aggregated, successful hypotheses of the past have the kind of truth that goes into a number system.
