Abstract

Hard incompatibilism is a view about free will and moral responsibility that has been developed and defended by Derk Pereboom for almost three decades (Pereboom 1995, 2001, 2014). Succinctly put, hard incompatibilists argue that we do not have free will because, whether determinism is true or false, we are subject to the freedom-undermining effects of causal luck (i.e. causal factors beyond our control). In recent years, Gregg Caruso has become a vocal advocate of hard incompatibilism, and he rests his “public health-quarantine model” and its non-retributive approach to criminal behavior squarely on the foundation of Pereboom’s free-will metaphysics (e.g. Caruso 2012, 2014, 2021, 2022; Pereboom and Caruso 2018, 2022; Dennett and Caruso 2021). More recently, biologist and science popularizer Robert Sapolsky has raised the public profile hard incompatibilism by claiming to endorse this position in his best-selling book Determined: A Science of Life Without Free Will (2023). In this book, I offer a refutation of hard incompatibilism and all instances of constructive incompatibilism. In short, I argue that two central central explanatory tenets of hard incompatibilism are in tension with one another, making it impossible for someone to argue for one without undermining their defense of the other in the process. I then point out that the arguments against hard incompatibilism also undermine Neil Levy's luck-pincer impossibilism (2011). Along the way, I explain why Robert Sapolsky is not a hard incompatibilist and is actually committed to the falsity of hard incompatibilism. In closing, I propose a way for skeptics like Caruso and Sapolsky to maintain their skepticism without any type of constructive incompatibilism as the foundation.
