Wouldn't an atheist reject philsophy altogether making the whole question moot?
It would be more at what one's definition of philosophy was.
Wikipedia writes:
Philosophy is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. It is distinguished from other ways of addressing fundamental questions (such as mysticism, myth, or the arts) by its critical, generally systematic approach and its reliance on rational argument. The word "philosophy" comes from the Greek φιλοσοφία (philosophia), which literally means "love of wisdom".
Love of Wisdom is what I would consider and that matters not whether a person is a Theist, Deist, Agnostic or Atheist.
The point is that science is knowledge and art is science being put to use. The 2 are intertwined and that is what philosophy is. Knowledge yields wisdom.
