Science is not a fixed, unchangeable body of propositions. After a thousand years the general face of science may be modified past recognition. Scientific hypotheses are questions put to nature. In the game of twenty questions no skilful player begins by guessing what he thinks most likely. He seeks to fix one feature at a time.

Science is defined in the dictionaries as systematized knowledge. But considered as one of the elements of the life of civilization science is not so much characterized by knowledge as by a resolute desire to know.

The whole discussion of the logical nature of the different kinds of possible signs makes up the first division of logic, or Speculative Grammar. The second division, Critic, discusses the relation of signs to their objects, that is, their truth.
