I am not completely settled on this issue myself. I read an interview with Galen Strawson recently in "A Very Bad Wizard" and afterward I felt like I was a hard-determinist, or something stronger than a compatibilist, but then I read a couple interviews with Peter Singer and parts of Parfit's new book "On what matters" and they both seem to hold convincingly that compatibilism is true.
Here are two Singer quotes on the subject of free will I found. He doesn't write too often on the subject; having read his entire "Peter Singer Under Fire" it is not mentioned even once:
first December 2000
Reason: Could it be that our behaviors are constrained so that we really aren't able to choose? Are we deluding ourselves into thinking that we can actually choose to do one thing or another?
Singer: Darwinian theory suggests that choices are constrained in a sense that statistically you can predict what most people will do under some circumstances. But that's different from the sort of first-person sense of freedom that we have, where we're facing a question and we have this strong sense that we are free to choose what to do. Really, we are free to choose in the sense that if I decide that this is what I'm going to do, I can get up and do it, even if statistically it's going to be rare for people to do that. The sense of freedom there is genuine. I'm what has been called a "compatibilist" or a "soft determinist"-I think determinism is true, but it doesn't eliminate the claim that we have a choice and that we are responsible for our choices. Determinism is true in the sense that if you knew everything about the world at state A, you would be able to predict what it would be like in state B later. But freedom is also real in the sense in which the world confronts us as a real capacity for choice. It's a mistake to simply dismiss it as an illusion. The kind of choice required for responsibility and for saying that someone is free is not something that is incompatible with the belief that their actions are caused. Think about the conditions for holding someone responsible: If they did something because they'd been drugged, then we say they're not free, they're not responsible. But if they did something because they sat there, they thought about it, and in the end the reasons and the values that they held led them to choose A rather than B, well, we say they're responsible. You could also say that if we'd known everything about them, we could have predicted that they would choose A rather than B. But they made a choice because they were free from all of those other factors which diminish responsibility.
and then in September 2006
Questioner: Does free will exist and if so, is it restricted to human beings, or can other animals have it?
Singer: In a deep metaphysical sense, I don't think free will exists. But we, and some animals, can make choices, and that's real enough, whatever the causes of our choices.
So after reading these two quotes I would say that I agree with what he is saying, but that his position strikes me as a little stronger on determinism than a "soft-determinist", his statement in 2006 seeming even stronger than it did in 2000. Maybe he was just playing to his libertarian interviewer in Reason.
I mean, often I feel like compatibilists are talking about something totally different when discussing free will than are libertarians. I've seen the word "neo-compatibilist" used by Owen Flanagan in "The Problem of the Soul," which I have heard is close to Dennett's view in "Elbow Room", but seems much stronger to me. He says:
The compatibilist, meanwhile, if he thinks free will is compatible with determinism, must have changed the subject. He cannot be saying that the Cartesian conception of free will is compatible with determinism because, well, it isn't. And indeed if one looks at the literature one will see that compatibilists invariably mean something different by free will than what the orthodox concept says it is.
The hard determinist, unlike the compatibilist, accepts the terms of the exercise as they are set and sees correctly that determinism is incompatible with free will, as the Cartesian conceives it. But both the compatibilist and the hard determinist make the same mistake. They both claim to know that determinism is true. But if what I have said about causation — there being both deterministic and indeterministic causes — is plausible, then neither can sensibly be said to know that determinism is true. Causation is ubiquitous. Ours is a causal universe. But no one yet knows the exact range of deterministic and indeterministic causation — assuming the universe contains some of each.
What to do? My proposal is this: Change the subject. Stop talk--a about free will and determinism and talk instead about whether and how we can make sense of the concepts of "deliberation," choice," "reasoning," "agency," and "accountability" (scorecard items) within the space allowed by the scientific image of minds. This is, I Hasten to admit, just what I accused the compatibilists of doing. Since they cannot be saying that free will is compatible with causation, either deterministic or indeterministic, they must be claiming that something else—hopefully something similar to free will—is compatible with causation.
It would be misleading to call my position compatibilism, however, since compatibilism seems to accept the terms of the standard debate about "free will and determinism." Since I have been trying to frame the pressing question in terms of the compatibility of "rational deliberation and choice and causation," or as the problem of the voluntary and the involuntary, it will be best to call my view neocompatibilism. I do claim that we can make sense of rational deliberation and choice in a causal universe. (The Problem of the Soul, pp.124-127)
Sorry for the long post, but this topic really rattles my brain. What do you all think?
