Every man is a philosopher. Every man has his own philosophy of life and his special view of the universe. Moreover, his philosophy is important, more important perhaps than be himself knows. It determines his treatment of friends and enemies, his conduct when alone and in society, his attitude to wards his home ,his work, and his country, his religious beliefs, his ethical standards, his social adjustment and his personal happiness. Nations, too, through the political or military party in power, have their philosophers of thought and actions. Wars are waged and revolutions incited because of the clash of ideologies, the conflict of philosophies, h has always been so. World War Two is but the latest and most dramatic illustration of the combustible nature of differences in social and political philosophy. Philosophy, says Plato, begins with wonder.

Many of our questions, however, will never have final answers. Men will always discuss the nature of justice and right, the significance of evil, the art of government, the relation of mind and matter, the search for truth, the quest for happiness, the idea of God, and the meaning of reality. The human race has reflected so long and often on these problems that the same patterns of thought recurs in almost every age. We should know what these thoughts are. We should know what answers have been suggested by those who have most influenced ancient and modern thought. We shall want to do our own thinking and find our own answers. It is, however, neither necessary nor advisable to travel alone. Others have helped dispel the darkness, and the light they have kindled may also illuminate our way. By saying' Every man is a philosopher' (Line 1, Paragraph 1), the author implies that
