Life is simply the reification of the process of living.

Scientific progress consists in the development of new concepts.

Mathematics is as little a science as grammar is a language.

Evolution as such is no longer a theory for a modern author. It is as much a fact as that the earth revolves around the sun.

Our understanding of the world is achieved more effectively by conceptual improvements than by discovery of new facts

most scientific problems are far better understood by studying their history than their logic.
