Essays discuss reason, self-control, self-definition, time, cause and effect, accidents, and responsibility, and explain why people want free will.

1. “All Theory is Against Free Will…” Powerful arguments have been leveled against the concepts of free will and moral responsibility since the Greeks and perhaps earlier. Some—the hard determinists—aim to show that free will is incompatible with determinism, and that determinism is true. Therefore there is no free will. Others, the “no-free-will-either-way-theorists,” agree that determinism is incompatible with free will, but add that indeterminism, especially the variety posited by quantum physicists, is also incompatible with free will. Therefore there is no free will. Finally, there are the a priori arguments against free will. These arguments conclude that it makes no difference what metaphysical commitments we hold: free will and ultimate moral responsibility are incoherent concepts. Why? Because in order to have free will and ultimate moral responsibility we would have to be causa sui, or ‘cause of oneself.’ And it is logically impossible to be self-caused in this way. Here, for example, is Nietzsche on the causa sui.

The question of whether humans have free will, like the question of the meaning of life, is one whose answer depends on how the question itself is interpreted. In his recent book Neurophilosophy of Free Will: From Libertarian Illusions to a Concept of Natural Autonomy, Henrik Walter examines whether free will is possible in a deterministic natural world, and he concludes that the answer is "It depends" (xi). He rejects a libertarian account of free will as internally inconsistent, but argues for a version of compatibilism that he calls "natural autonomy." Natural autonomy, or "giving oneself laws" (8), is a successor concept to libertarian free will, and it provides for a self-determination that is consistent with a deterministic and fully physical world. Walter covers a lot of ground in this book. He debunks dualism, examines classical and modern physics, critiques radical constructivism, and utilizes chaos theory, and he refers to figures from St. Augustine to Humberto Maturana, Dennett, Einstein, Hegel and Nozick. This book could be seen as encompassing two distinct projects. The first project is a defense of what Walter calls "neurophilosophy" as a methodology for answering traditional philosophical questions. This methodology is more commonly known as "cognitive science," and Walter accepts the naturalistic premises that underlie most of the work being done by cognitive scientists today. The second project is an application of the neurophilosophical methodology to the traditional question of whether free will is compatible with determinism. The defense of a neurophilosophical methodology is concentrated in the second section of the book, whereas the first and third sections focus on the issue of free will. In the first section Walter presents a thorough overview of the free will debate. It is the final third of the book that warrants the most attention, for this is where the original work is concentrated. Before we examine Walter's contribution to the free will debate, let us briefly look at his historical analysis and the neurophilosophical method that he advocates..

It is widely held that free speech is a distinctive and privileged social kind. But what is free speech? In particular, is there any unified phenomenon that is both free speech and which is worthy of the special value traditionally attached to free speech? We argue that a descendent of the classic Millian justification of free speech is in fact a justification of a more general social condition; and, via an argument that 'free speech' names whatever natural social kind is justified by the best arguments, that free speech is therefore this more general condition. This condition involves not merely the orthodox freedom (in some sense) of speakers to distribute words, but also two less frequently acknowledged dimensions of free speech: audience understanding and consideration. We conclude with some discussion of the policy implications of this conception of free speech.

Daniel Dennett maintains that regardless of determinism humans are both free to act and have a meaningful existence. Yet Dennett’s compatibilism entails that a felicity-advancing interaction with the world is all that we could wish for, which seems false. I also argue that Dennett’s attempt to define the terms central to this metaphysical debate fails. The weaknesses of Dennett’s case suggest that he is motivated more by his desire to complete the naturalistic project than he is by the pursuit of philosophical coherence.

Free will sceptics claim that we do not possess free will—or at least, that we do not possess nearly as much free will as we think we do. Some free will sceptics hold that the very notion of free will is incoherent, and that no being could possibly possess free will (Strawson this volume). Others allow that the notion of free will is coherent, but hold that features of our cognitive architecture prevent us from possessing free will. My concern in this chapter is with views of the second kind. According to an increasingly influential line of thought, our common-sense commitment to the existence of free will is threatened in unique ways by what we are learning from the sciences of human agency.

I examine the extent to which Dennett’s account in Freedom Evolves might be construed as revisionist about free will or should instead be understood as a more traditional kind of compatibilism. I also consider Dennett’s views about philosophical work on free agency and its relationship to scientific inquiry, and I argue that extant philosophical work is more relevant to scientific inquiry than Dennett’s remarks may suggest.
