- SUMMARY: There's been a lot of activity following my original posting, at
- least by the standards of my earlier efforts. In this posting I attempt to
- clarify some confusions and respond to a few criticisms, and also offer an
- analysis of the debate intended to characterise the fundamental issues.

- I disagree fundamentally. Certainly there are many senses of possibility, but
- the sense relevant to `free will' is not what is sometimes called `epistemic'
- possibility, as suggested by Holmes. This is, perhaps, well illustrated by
- looking at the way we deal with attributions of responsibility. If I believe
- of a person who stole my watch that that person _thought_ s/he could have
- chosen not to take the watch, but was in fact mistaken then I cannot con-
- sistently hold him/her responsible. If we believe that determinism is true
- with respect to our actions then we cannot hold ourselves, or anyone else,
- responsible for _anything_.
-
- Rather than waste space here I refer those not already following it to the
- `Free Will and Morality' thread in talk.philosophy.misc which is dealing with
- this question in reasonable detail. I recommend that _this_ thread look at
- the technical aspects of the immanent causality question, which is a less
- tired topic anyway.

-
- Anyone who thinks that `free will' depends upon `loopholes in the laws of
- physics' is just being opportunistic, and I certainly do not think that for a
- moment. Insofar as physics is the project of establishing the truth about the
- physical world it is co-extensive with philosophy, and whether we have `free
- will' or not will be a matter of the nature of that world, not about ways that
- nature is cheated. That is why I am attempting to draw a distinction between
- determinism and causality, and to preserve the latter. I am not offering any
- sort of `exceptionalism' where our choices break or bend the laws of physics,
- I find such theories ridiculous and dualistic.

-
- I agree completely, and it was a major objective of my original posting to get
- away from equating freedom with indeterminism as quickly as possible to get at
- the _problem_.

-
- `Real free will'? This seems to be no free will at all, and I have no idea
- what you mean by your contrast with `absolute free will' here. If I believe
- that my actions are determined in principle (leaving QM aside for now) then
- even though I do not know the details of any given action, or even of all of
- them, I cannot approach them in the same way as if I thought they were really
- up to _me_. Ignorance about X is surely not adequate reason to assert that
- not-X. This is certainly not what you are saying, but I cannot see what the
- logical difference is. Also: What do we `need' this form of free will for?
-
- PART II: Analysis
-
- There are at least two major strands of discussion here, (1) about
- the definition of free will, and (2) about the relationship between
- any and all of the definitions and determinism. Some discussion of
- what constitutes responsibility is also coming up, but the `Free
- Will and Morality' thread is still active, so I will not repeat
- myself here.
-
- (1) Definition.
-
- My original definition was:
-
- > Voluntarism (the thesis that we `have' free will, or are free, or
- > whatever) holds that we _choose_ our actions, that we cause them to
- > take place, _AND_ that we are capable of acting other than we do in
- > at least some cases. It is in these cases that we are responsible.
-
- which nobody has directly attacked here. Holmes line of argument,
- however, opens up a range of crucial questions about our _knowledge_
- of what we do, and actually or allegedly could have done. This
- changes the discussion, since what we can know of a situation is not
- necessarily the truth about it.
-
- A number of questions arise here:
-
- - Is the question as to whether or not humans have `free will' a fac-
- tual/ontological one, or is it rather a matter of our partial and
- perhaps subjective self-knowledge?
-
- - If the question is said to be to do with our self-knowledge, then
- what is the relationship between specific parts of that knowledge,
- and our general beliefs about the nature of the world? [ie. between
- my belief that I could have done other than I did in some case, and
- my belief in determinism, or indeterminism.]
-
- - If, on the other hand, the question is ontological then what sort of
- ontolgy can do justice to both our experience of the physical world,
- and that of ourselves? [ie. which does not have the ridiculous con-
- sequence, eg, that when I drop my pencil it could choose to fall
- sideways.]
-
- (2) `Free Will' and in/determinism.
-
- I think that a central point here is that responsibility is
- meaningless unless we are the authors of our actions, and unless we
- could act other than we do. To hold a person responsible for some-
- thing they did not cause is as ridiculous as holding them
- responsible for something they could not have prevented. That ac-
- tion is causal rules out indeterminism. That it involves pos-
- sibility rules out determinism. I think that anyone trying to
- equate free will with randomness is not worth talking to, which
- leaves two major options: (1) I am correct, and `free will' either
- does not exist, or another ontology is needed, or (2) I am in-
- correct, and responsibility is in some sense compatible with
- determinism.
-
- Those who follow option (2) should provide an analysis of the
- flaws (there are many) in the proto-ontology I offered, and/or ex-
- plain a deterministic view which fully deals with the problem.
-
- Those who favour option (1) should try to make a lot more sense of
- the proto-ontology, and deal with the criticisms which arise from
- the determinists. OR they should explain how we can come to be-
- lieve we have `free will' when in fact we don't. [Note that this
- option is conditional.]
-
- In both cases a central question is `what is it to be an agent?'
- ie. `is an agent a thing of some sort, which can truly be said to
- cause acts to take place?'
