Peirce’s Philosophy of Science

  • A. J. Ayer


There are in science’, says Peirce, ‘three fundamentally different kinds of reasoning.’ These three kinds, which were already distinguished by Aristotle, are Deduction, Induction, and one for which Peirce most frequently uses the term Abduction, though he thinks that Retroduction would be a better name for it and sometimes also calls it Hypothesis. He also admits Analogy, but does not put it on a level with the other three, since he thinks that it combines the characters of Induction and Abduction.1
