Yes, Determinists, There Is Free Will

George Musser in Nautilus:

It’s not just in politics where otherwise smart people consistently talk past one another. People debating whether humans have free will also have this tendency. Neuroscientist and free-will skeptic Sam Harris has dueled philosopher and free-will defender Daniel Dennett for years and once invited him onto his podcast with the express purpose of finally having a meeting of minds. Whoosh! They flew right past each other yet again. Christian List, a philosopher at the London School of Economics who specializes in how humans make decisions, has a new book, Why Free Will Is Real, that tries to bridge the gap. List is one of a youngish generation of thinkers, such as cosmologist Sean Carroll and philosopher Jenann Ismael, who dissolve the old dichotomies on free will and think that a nuanced reading of physics poses no contradiction for it.

List accepts the skeptics’ definition of free will as a genuine openness to our decisions, and he agrees this seems to be at odds with the clockwork universe of fundamental physics and neurobiology. But he argues that fundamental physics and neurobiology are only part of the story of human behavior. You may be a big bunch of atoms governed by the mechanical laws, but you are not just any bunch of atoms. You are an intricately structured bunch of atoms, and your behavior depends not just on the laws that govern the individual atoms but on the way those atoms are assembled. At a higher level of description, your decisions can be truly open. When you walk into a store and choose between Android and Apple, the outcome is not preordained. It really is on you.

Skeptics miss this point, List argues, because they rely on loose intuitions about causation. They look for the causes of our actions in the basic laws of physics, yet the concept of cause does not even exist at that level, according to the broader theory of causation developed by computer scientist Judea Pearl and others. Causation is a higher-level concept. This theory is fully compatible with the view that humans and other agents are causal forces in the world. List’s book may not settle the debate—what could, after thousands of years?—but it will at least force skeptics to get more sophisticated in their own reasoning.
