The Nature of Scientific and Other Hypotheses
Bulletin of the British Society for the History of Science
of Paper read on 16th January, 1950 Philosophy is knowledge gained by the analysis of knowledge, or by the re-synthesis of the products of such analysis. Knowledge is derived by two processes, perception of externality, and introspection. Facts are products of perceptions stored in the memory, and may be either public or private. Public facts are scientific, legal or historic. Historic facts depend upon memories of people already dead. Legal facts depend upon the memories of the living.
