Understanding the Question: Philosophy and its History

What is the relevance of the history of philosophy to philosophy as such? This is not the question, what is the reason for studying the history of philosophy? This question is easy to answer. Philosophy is part of our culture, and the history of our culture is worth studying, if anything is. Nor is it the question, should academic institutions teach the history of philosophy as part of a philosophical education? It is widely accepted that students should be taught the history of philosophy, even if philosophy itself is not considered an essentially historical discipline. An education in the history of philosophy is part of a broadly humanistic university education, and something of value for this reason alone, without it being necessary for anyone who actually pursues philosophy creatively and systematically to have to take history into account.
