If a man is skeptical about the role of philosophy in life, let him put aside philosophy books. Let him leave the cloistered ivory tower of theory and plunge into the sprawling realms of practice. Let him observe the concretes of his society's cultural life--its politics, its economics, its education, its youth movements, its art and religion and science. In every area, let him discover the main developments and then ask: why? In every area, the actors themselves will provide the answer. They seldom provide it in the form of philosophical speeches. Frequently they offer moral declarations. Predominantly, however, they offer passing references, vague implications, and casual asides--which seem casual, except that the actors cannot avoid making them and counting on them.
