Unfortunately, someone stole it from me, but it was an introduction to philosophy book that really opened up my mind, introducing philosphers including Socrates, Plato, Aristotle, Augustine, Aquinas, Confuscious, Hobbes, Hume, Foucault, Kant, Kierkegaard, Lao Tzu, Locke, Marx, Mill, Rand, and more. It basically covered who they were, how they grew up, and what they've stated that has helped contribute to our society. Very interesting book. Can't recall the exact name of it, but I don't the book anymore to do my research and read any of these philosophers.
