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.

Nearly a century after his wrenching death, the Portuguese poet Fernando Pessoa (1888-1935) remains one of our most enigmatic writers. Believing he could do "more in dreams than Napoleon," yet haunted by the specter of hereditary madness, Pessoa invented dozens of alter egos, or "heteronyms," under whose names he wrote in Portuguese, English, and French. Unsurprisingly, this "most multifarious of writers" (Guardian) has long eluded a definitive biographer—but in renowned translator and Pessoa scholar Richard Zenith, he has met his match.
