Abstract
The understanding which a philosopher has, can have, or ought to have of the work of his predecessors cannot be historical in character. Collingwood is right about evidence and the nature of historical understanding. But what a philosopher wrote is not evidence of his thought, it is his thought. The ideas and doctrines of past philosophers are not themselves in the past and do not therefore belong to a special period of the past. Philosophic ideas cannot be said to be in time at all. Different interpretations of particular passages are strengthened or weakened by the citation of matters of historical fact, just as they may be by linguistic or literary knowledge. Such a clarification may enable us to resolve the question of the consistency of a passage with the rest of an author's work, but it does not destroy the philosophic character of the question
