《堅決的意志：沒有自由意志的人生，其背後的科學》（Determined: A Science of Life without Free）提出跨領域的科學研究，從神經學、動物學、社會學、哲學……等各種面向，全面檢視人類社會中的個體，在某一個當下、或終其一生，在理智與情感、刺激與反應之間，是否依照自由意志做出行為決定。
 
　　以跳脫傳統、充滿說服力的文字，辯證為什麼自由意志不過只是一種幻覺，而接受這個想法，又為什麼不會使秩序崩潰，反將帶領我們打造更人性化的社會。這本令人大開眼界的書作，將大膽顛覆人類幾個世紀以來的認知，絕對會引起熱烈討論。(文/博客來編譯)
 
媒體評論：

• 「幾乎沒有人，能像著名的神經科學家羅伯特·薩波爾斯基那樣，深入解析人類大腦。」

——《舊金山紀事報》（San Francisco Chronicle）今年秋季最期待大書

• 「薩波爾斯基以獨特的風格提出了一個有力的論點，揭示為何自由意志只不過是一種幻覺…… 幽默、絕妙的筆法，十分好讀。」

——《書單》雜誌（Booklist）高度推崇

One of our great behavioral scientists, the bestselling author of Behave, plumbs the depths of the science and philosophy of decision-making to mount a devastating case against free will, an argument with profound consequences

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.

Determined offers a marvelous synthesis of what we know about how consciousness works--the tight weave between reason and emotion and between stimulus and response in the moment and over a life. One by one, Sapolsky tackles all the major arguments for free will and takes them out, cutting a path through the thickets of chaos and complexity science and quantum physics, as well as touching ground on some of the wilder shores of philosophy. He shows us that the history of medicine is in no small part the history of learning that fewer and fewer things are somebody’s ＂fault＂; for example, for centuries we thought seizures were a sign of demonic possession. Yet, as he acknowledges, it’s very hard, and at times impossible, to uncouple from our zeal to judge others and to judge ourselves. Sapolsky applies the new understanding of life beyond free will to some of our most essential questions around punishment, morality, and living well together.By the end, Sapolsky argues that while living our daily lives recognizing that we have no free will is going to be monumentally difficult, doing so is not going to result in anarchy, pointlessness, and existential malaise. Instead, it will make for a much more humane world.
