It seems like, if I'm trying to make up my mind about philosophical questions (like whether moral realism is true, or whether free will is an illusion) I should try to find out what professional philosophers think the answers to these questions are.

If I found out that 80% of professional philosophers who think about metaethical questions think that moral realism is true, and I happen to be an anti-realist, then I should be far less certain of my belief that anti-realism is true.

But surveys like this aren't done in philosophy (I don't think). Do you think that the results of surveys like this (if there were any) should be important to the person trying to make a decision about whether or not to believe in free will, or be an moral realist, or whatever?

My answer to this depends on what you mean by "professional philosophers who think about". You have to be aware that subfields have selection biases. For example, the percent of philosophers of religion who think God exists is much, much larger than the percent of professional philosophers generally who think God exists. This is because if God does not exist philosophy of religion ceases to be a productive area of research. Conversely, if you have an irrational attachment to the idea that God exists this than you are likely to spend an inordinate amount of time trying to prove one exists. This issue is particularly bad with regard to religion but it is in some sense generalizable to all or most other subfields. Philosophy is also a competitive enterprise and there are various incentives to publishing novel arguments. This means in any given subfield views that are unpopular among philosophers generally will be overrepresented.

So the circle you draw around "professional philosophers who think about [subfield x] questions" needs to be small enough to target experts but large enough that you don't limit your survey to those philosophers who are very likely to hold a view you are surveying in virtue of the area they work in. I think the right circle is something like 'professional philosophers who are equipped to teach an advanced undergraduate course in the subject'.

Edit: The free will question will depend on what you want out of a conception of free will. But the understanding of free will that most lay people have is totally impossible.

Seconded. There are a lot of libertarians-about-free-will who study free will, but nobody I've talked to has ever heard of anyone changing their mind on the subject of free will (except inasmuch as learning new words to describe one's beliefs counts) - so this has to be almost entirely due to more libertarians finding free will an interesting thing to study.

I've definitely changed my mind on free will. I used to be an incompatibilist with libertarian leanings. After reading Daniel Dennett's books, I changed my mind and became a compatiblist soft determinist.

Are you a professional philosopher/ were you a professional philosopher when you were an incompatibilist with libertarian leanings? I'd say the vast majority of those untrained in philosophy hold the view you held and the most rational/intelligent of them would change their minds once confronted with a decent compatiblist argument.

Edit: I'm being a little unfair. There are plenty of smart people who disagree with us.

No, I wasn't, and I agree with you. Defending philosophical positions as a career creates a bias where you're less likely to change your mind (see Cialdini's work on congruence: e.g. POWs in communist brainwashing camps who wrote essays on why communism was good were more likely to support communism afer release). But even so, professional philosophers do change their mind once in a while.

Absolutely! I tentatively hold the thesis that professional philosophers even make progress on understanding some issues. But there seem to be a couple positions that professional philosophers rarely sway from once they hold those positions and I think Alicorn is right that metaphysical libertarianism is one of these views.

Free will libertarianism is also infected with religious philosophy. There are certainly some libertarians with secular reasons for their positions but a lot of the support for this for position comes from those whose religious world view requires radical free will and if they didn't believe in God they wouldn't be libertarians. Same goes for a lot of substance dualists, frankly.

Jack:

I think I agree with everything you say in response to my original post.

It seems like you basically agree with me that facts about the opinions of philosophers who work in some area (where this group is suitibly defined to avoid the difficulties you point out) should be important to us if we are trying to figure out what to believe in that area.

Why aren't studies being carried out to find out what these facts are? Do you think most philosophers would not agree that they are important?

Comment author: Jack 23 November 2009 10:02:22PM 1 point [-]

Yeah, I've felt for a while now that philosophers should do a better job explaining and popularizing the conclusions they come to. I've never been able to find literature reviews or meta-analysis, either. Part of the problem is definitely that a lot of philosophers are skeptical that they have anything true or interesting to say to non-philosophers. Also, despite some basic agreements about what is definitely wrong philosophers, at least with a lot of issues have so many different views that it wouldn't be very educational to poll them. Also, a lot of philosophy involves conceptual analysis and since it is really hard to poll a philosophical issue without resorting to concepts you might have a lot of respondents refusing to accept the premises of the question.

But none of these arguments are very good. If I ever make it in the field I'll put one together.
