Robert Sapolsky’s Behave, his now classic account of why humans do good and why they do bad, pointed toward an unsettling conclusion: We may not grasp the precise marriage of nature and nurture that creates the physics and chemistry at the base of human behavior, but that doesn’t mean it doesn’t exist. Now, in Determined, Sapolsky takes his argument all the way, mounting a brilliant (and in his inimitable way, delightful) full-frontal assault on the pleasant fantasy that there is some separate self telling our biology what to do.

Humans have long thought of their bodies and minds as separate spheres of existence. The body is physical. But the mind is mental; it perceives, remembers, believes, feels, and imagines. Although modern science has largely eliminated this mind-body dualism, people still tend to imagine their minds as separate from their physical being. Even in research, the notion of the "self" as somehow distinct from the rest of the organism persists. Joseph LeDoux argues that we have hit an epistemological wall—that ideas like the self are increasingly barriers to discovery and understanding.

Cat's Cradle is Vonnegut's satirical commentary on modern man and his madness. An apocalyptic tale of this planet's ultimate fate, it features a little person as the protagonist; a complete, original theology created by a calypso singer; and a vision of the future that is at once blackly fatalistic and hilariously funny.

Daniel C. Dennett—preeminent philosopher and cognitive scientist—has spent his career creating the basis for a naturalistic account of consciousness with acumen and elegance. I’ve Been Thinking traces the development of Dennett’s own intellect and instructs us how we too can become good thinkers. Dennett’s restless curiosity leads him from his childhood in Beirut to Harvard, and from Parisian jazz clubs to “tillosophy” on his tractor in Maine. Along the way, he reveals the breakthroughs and misjudgments that shaped his paradigm-shifting philosophies.

What does it mean to “be you” - that is, to have a specific, conscious experience of the world around you and yourself within it? There may be no more elusive or fascinating question. Historically, humanity has considered the nature of consciousness to be a primarily spiritual or philosophical inquiry, but scientific research is now mapping out compelling biological theories and explanations for consciousness and selfhood.
