Faded spine, minor signs of secondhand wear.

Daniel C. Dennett's now-classic book blends philosophy, psychology and neuroscience - with the aid of numerous examples and thought-experiments - to explore how consciousness has evolved, and how a modern understanding of the human mind is radically different from conventional explanations of consciousness.

What people think of as the stream of consciousness is not a single, unified sequence, the author argues, but 'multiple drafts' of reality composed by a computer-like 'virtual machine'.

Dennett explains how science has exploded the classic mysteries of consciousness: the nature of introspection, the self or ego and its relation to thoughts and sensations, the problems posed by qualia, and the level of consciousness of non-human creatures.
