Philosophy -- dry and remote? Think again. It's as relevant as tonight's news, as immediate as the choices you make in a career. If you want to interact wisely with the world you live in, you need to understand the ideas that shape its commerce, launch its humanitarian efforts, trigger its wars, and profoundly impact the way you yourself approach God, life, and relationships. Postmodernism, Platonism, Humanism, Existentialism, Feminism, Rationalism, Fundamentalism, New Age . . . They're more than just terms. They're structures of thought you encounter constantly. This book gives you a fundamental grasp of what they are and how they influence your dealings with the world . . . and its dealings with you. You'll gain essential insights into over 40 of the world's major thinkers. Plato, Aristotle, Augustine, Descartes, Kant, Locke, Marx, Nietsche, Freud, Wittgenstein . . . A Brief Guide to Ideas introduces to you these and many more of the great philosophers. You'll develop a working knowledge of numerous key ideas and movements.
