Clear, concise, and easy to read, this eye-opening book offers readers a walk through some of the greatest and most thought-provoking arguments from classical, modern, and contemporary philosophy. Along the path, it looks closely at: Socrates' answer to the question, "Did God create morality, or did he discover it?"; what Descartes meant when he said, "I think, therefore I am"; why Berkeley thought that matter and the material world don't really exist; an argument that shows that God necessarily exists; whether we can really know anything at all; and finally, why (and whether) you owe any allegiance to the rules or laws of your government and society. An expert educator with more than twenty years' experience bringing these ideas to life for students, the author presents these influential, surprising philosophical arguments in a delightful and accessible way. While the topics span the four corners of western philosophy, the unifying theme here is one about philosophical skepticism, and how it's applied as a tool for greater intellectual inquiry. The book doesn't presuppose any familiarity with philosophy, though it certainly rewards those with a strong curiosity about big important ideas. After all, as Plato famously quipped, philosophy begins in wonder.
