Leon Vlieger in The Inquisitive Biologist:
Robert M. Sapolsky is a professor of biology and neurology who you may remember from his 2017 best-seller Behave, a 790-page behemoth on the biology of human behaviour. Before delving in, let me immediately highlight that Determined is accessible, well-researched, witty, and irreverent; it regularly made me chuckle. For a book that could have gotten bogged down in philosophical and neurobiological jargon, this one is a joy to read.
Clearly, Sapolsky does not believe in free will. But what does that mean? He falls in the minority camp of hard incompatibilism: the world is deterministic (i.e. events result from both prior events and the laws of nature), this is incompatible with free will, and we are thus not morally responsible for our actions.
