Philosophy is an activity: it is a way of thinking about certain sorts of question. - Nigel Warburton

Some students of philosophy have unreasonably high expectations of the subject. They expect it to provide them with a complete and detailed picture of the human predicament. They think that philosophy will reveal to them the meaning of life, and explain to them every facet of our complex existences. Now, although studying philosophy can illuminate fundamental questions about our lives, it does not provide anything like a complete picture, if indeed there could be such a thing. Studying philosophy isn’t an alternative to studying art, literature, history, psychology, anthropology, sociology, politics, and science.

Another reason for studying philosophy is that it provides a good way of learning to think more clearly about a wide range of issues.

What is philosophy? This is a notoriously difficult question. One of the easiest ways of answering it is to say that philosophy is what philosophers do, and then point to the writings of Plato, Aristotle, Descartes, Hume, Kant, Russell, Wittgenstein, Sartre, and other famous philosophers. However, this answer is unlikely to be of much use to you if you are just beginning the subject, as you probably won’t have read anything by these writers.
