Philosophy

Philosophy, from the Greek for "love of wisdom", is an intellectual discipline that studies the nature of reality, knowledge and morality based largely on logical reasoning, as opposed to empirical investigation (as in science). It is commonly divided into logic, ethics, aesthetics, metaphysics, and epistemology.

In a more general sense, philosophy may refer to the set of beliefs or values by which one lives.
