Bertrand Russel's The Problems of Philosophy is a classic text that both analyzes and explains the best ways to approach philosophical discussion. First published in 1912, the book is a must read because it does not simply look at one set philosophy, but rather all thinking styles, ranging from the early days of Aristotle and Plato up through David Hume and John Locke. In this way, the text lays out many thought provoking questions, and, focusing on the birth of knowledge, brings many questions to light that are applicable to all people regardless of background or age.
