In dark days, men need a clear faith and a well-grounded hope; and as the outcome of these, the calm courage which takes no account of hardships by the way. The times through which we are passing have afforded to many of us a confirmation of our faith. We see that the things we had thought evil are really evil, and we know more definitely than we ever did before the directions in which men must move if a better world is to arise on the ruins of the one which is now hurling itself into destruction. We see that men's political dealings with one another are based on wholly wrong ideals, and can...

A European lately arrived in China, if he is of a receptive and reflective disposition, finds himself confronted with a number of very puzzling questions, for many of which the problems of Western Europe will not have prepared him.

In fact, however, all the world...

THE attempt to conceive imaginatively a better ordering of human society than the destructive and cruel chaos in which mankind has hitherto existed is by no means modern: it is at least as old as Plato, whose Republic'' set the model for the Utopias of subsequent philosophers.

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.
