Abstract

We are free to get our theories where we will. As Einstein said, the emergence of a theory is like an egg laid by a chicken, "auf einmal ist es da.1" In practice theories are usually derived as improvements on earlier theories, as better tools are refinements of earlier, cruder ones; and they are directed explanatorily not at the facts of their own construction but at independently specifiable facts which, left unexplained by earlier theories, have therefore refuted them. A new theory should cogently and directly explain all that its predecessors explain and in addition those particular facts which they conspicuously do not explain. The ideal is to have the simplest possible premises explaining most precisely the widest possible range of problematical facts. · 1. Ronald W. Clark, Einstein: The Life and Times , p.173 n. Ralph W.
