This is a book about the big questions in life: knowledge, consciousness, fate, God, truth, goodness, justice. It is for anyone who thinks there are big questions lurking out there, but does not know how to approach them. Written by the author of the bestselling Oxford Dictionary of Philosophy, Think sets out to explain what they are and why they are important. Blackburn has produced the one book every smart person should read to understand, and even enjoy, the key questions of philosophy, ranging from those about free will and morality to what we can really know about the world around us.
