Here is part of a 1977 video of W.V.O. Quine being interviewed by Brian Magee on BBC TV.
Magee introduces Quine as "a philosopher at the very summit of world reputation."
In this clip, Quine talks about how philosophy is on a continuum with science but is also different from it. He gives the examples of history and engineering as being at the most applied end of the sciences and philosophy and mathematics being at the most abstract end.
Magee asks Quine about the sorts of questions that philosophy takes up. Quine says that the question of how the world began is for physicists to deal with. The question of how life began is a question for biologists. And the question of why the world or life began is not a question at all, not even one for philosophers. It's merely a pseudo-question, because it doesn't have an answer.
Finally, Quine divides philosophy into two categories--ontology and epistemology. Philosophy deals with questions about what there is and questions about what we can know. On the subject of what there is, Quine says that objects are either material or mathematical.
Well, I'm an undisputed fan of Quine (see this website)--but doesn't this seem like a narrow view of philosophy?
