The Big Picture is subtitled An Honest Examination of God, Science and Purpose, and for once you would be absolutely right to judge a book by its cover. It is an account of an intelligent, inquisitive, scientific mind asking itself how the world hangs together. Chapter 1 examines, at a popular and accessible level, the basics of logic and epistemology—without ever using the word—paying special attention to unspoken assumptions and the ways in which our thinking can be led astray.
