ABSTRACT
There are many jokes about the futility of philosophizing, and it is true that science is a much more business-like occupation in which every achievement, however modest, may give you sound satisfaction. For there your work stands, public, compelling and permanent; it testifies that for one moment you were allowed to make intellectual history. You have disclosed something that had never been known before and that—you may hope—will henceforth continue to be known as long as the memory of our civilization endures.
