Defining and explaining philosophy is no easy task - the very nature of the subject seems to defy description. The problem is that philosophy, in one way or another, ends up touching upon nearly every aspect of human life. Philosophy has something to say when it comes to science, art, religion, politics, medicine, and a host of other topics. This is also why a basic grounding in philosophy can be so important for irreligious atheists.
The study of philosophy is usually approached in one of two different ways: the systematic or topical method and the historical or biographical method. Both have their strengths and weaknesses and it is often beneficial to avoid focusing on one to the exclusions of the other, at least whenever possible. For irreligious atheists, though, the focus should probably be more on the topical than on the biographical method because that will provide clear overviews of relevant issues.
