Book excerpt: Ideal for courses in ancient philosophy or ancient and medieval philosophy, The Great Conversation: A Historical Introduction to Philosophy, Volume I: Pre-Socratics through Descartes covers the same material as the first half (chapters 1-13) of author Norman Melchert's longer volume, The Great Conversation. Tracing the exchange of ideas among history's key philosophers, the book demonstrates that while constructing an argument or making a claim, one philosopher almost always has others in mind. The sixth edition features coverage of Taoism; key terms, boldfaced throughout and listed at chapter ends; brief and provocative quotations that stimulate thought and provoke questions; a new section on how to read philosophy; and a new appendix--Writing a Philosophy Paper.
