I do not see the link between unchanging logical laws and unmoving physical objects.

You have simply slipped a mental cog, as it stands this is not good logic.

aletheist,

if the above were the definition of Libertarian free will, then a will that is simply subject to random influences would qualify. But of course when this is pointed out, the Libertarian will immediately amend the above to include the stipulation that it is a "genuine" choice, and not just a random event. And that is where it becomes, at least on the face of it, self-contradictory.

There is no need to amend my definition--it already includes the word "genuine". And what is "self-contradictory" about stipulating that it be a "genuine" choice--one that involves the intentional exercise of active power, not just deterministic and/or random effects?

It's not the "genuine" that is problematic. It is the "and not just a random event" part that gives us trouble. Again, the problem being that without explaining the special (and as yet, still not clearly defined) usage of "random", the statement appears to just be saying that it is, and is not, non-deterministic.

Again, perfectly consistent with P simply being made up from ordinary matter which, due to the nature of quantum mechanics, behaves in an implicitly random way to some degree.

You cannot just dismiss this formalization so easily. Does "ordinary matter" have active power?

Of course it does. I can't imagine how you could be interpreting "active power" in such a way that ordinary matter could not have it.

Can "ordinary matter" exert such power as a first, unmoved mover?

Sure. As far as we can tell, it does it all the time. Every time a quantum event occurs, it is an uncaused event, so in effect, all matter could be considered to have "first mover" status.

And, of course, any object, ordinary matter or otherwise, that exhibits non-determistic behavior is, by definion, a first mover.

Does "ordinary matter" have the categorical ability to refrain from exerting such power?

Not really sure what you mean by that. Clearly certain objects made from ordinary matter do have the ability to refrain from taking actions that they are capable of taking.

Can "ordinary matter" act for the sake of reasons?

I don't see why not. Our brains do it all the time.

In fact, our brains do all the things you mention above, and yet they are made of ordinary matter.

Where do you see randomness in any of these statements? Where do you see self-contradiction?

I only see self-contradiction in the assertion that something could be both non-deterministic, and not random. Again, you have not explained what you mean by random in a way that allows me to make sense of such a statement.

Not at all--what Moreland means by "active power" is impossible if determinism is true.

Then I have no idea what he means by "active power", or what it has to with what those words are conventionally used to refer to.

J. P. Moreland wrote:
Active power is a primitive notion with a sense that is ultimately understood ostensively in acts of first-person introspective awareness of one's own initiation of change. A characteristic mark of active power is the ability to initiate motion, to bring something about. Active power is a dual ability to exert or refrain from exerting one's power. So understood, it is impossible for an exercise of active power to be causally necessitated by prior events.

I'm following up to here. But at this point, this appears to be a claim about active power, and not part of the definition of it. I don't see how this claim follows from the definition preceeding it.

At least, not in any way that doesn't just amount to applying a rather odd definition to the word "ability".

A first-mover is a substance that has active power. The notion of categorical ability in (3) has two important aspects to it. First, it expresses the type of ability possessed by a first-mover that can exercise active power, and as such it contrasts with the conditional ability employed by compatibilists. Second, categorial ability is a dual ability: if one has the ability to exert his power to do (or will to do) a, then one also has the ability to refrain from exerting his power to do (or will to do) a. Finally, (4) expresses a view of reasons as irreducible, teleological goals for the sake of which a person acts. In general, we may characterize this by saying that person s e'd (e.g., went to the kitchen) in order to r (e.g., get coffee or satisfy s's desire for coffee). This characterization of action, according to (4), cannot be reduced to a causal theory of action that uses belief or desire event causation.

Still no indication of how this differs from randomness, or how randomness fails to deliver what he is claiming is required. The only part that seems to touch on this is (4), which I really can't make any sense out of.

Only because you still insist that non-deterministic=random, an equivalence that I have rejected over and over. Unfortunately, I do not seem to be able to articulate why I reject it, at least not in a way that you will accept. It just seems clear to me that if I am in control of my decisions, then they cannot possibly be determined (because they are not dictated completely by prior events) and they cannot possibly be random (because they are not governed purely by chance). There has to be a "third way".

I am under the impression that it has not been definitively established whether quantum events are truly uncaused or simply have causes that we do not yet understand. In any case, I am not aware of anyone else ever suggesting that quanta are "first movers" in the same sense as free human agents.

This obviously begs the question. I deny that our brains do any of this; only our minds have these capabilities, and I am aware of no good reason for thinking that the mind is somehow reducible to the brain.

Well, then I guess I give up. Again, it seems perfectly clear to me; not that I am offering that as an argument! sticking out tongue

aletheist,

You misunderstand me. What I said is that on the face of it, the statement appears to be self-contradictory. That is, until such time as the libertarian makes it clear that they do not mean by "random" what I thought they meant, it appears to be self-contradictory.

The problem I have now that you have clarified that you mean by "random" something more than just "non-deterministic", is that I don't know what more you mean by it, or how your "agent" and a random system are different.

Unfortunately, I do not seem to be able to articulate why I reject it, at least not in a way that you will accept. It just seems clear to me that if I am in control of my decisions, then they cannot possibly be determined (because they are not dictated completely by prior events) and they cannot possibly be random (because they are not governed purely by chance). There has to be a "third way".

Well, technically speaking, there is a third way. But that third way is still determinism. It is just non-temporal determinism, where events are completely dictated by boundary conditions, which need not lie entirely in the past.

But presumably you reject this as well. There cannot possibly be a non-deterministic third way, because all it means to say that it is governed by chance, is that its behavior is not completely dictated by some set of conditions. "Chance" is a trick of language we use, in order to speak about something that did not have a cause, as though it did. Saying "X happened due to chance" is exactly the same as saying "there is no reason why X happened".

If you take "governed by chance" to mean something more than that, then you need to specify what more than that it is.

Every time a quantum event occurs, it is an uncaused event, so in effect, all matter could be considered to have "first mover" status.

I am under the impression that it has not been definitively established whether quantum events are truly uncaused or simply have causes that we do not yet understand.

I was speaking in the context of current quantum theory. In any event, suffice it to say that if quantum events are uncaused, then all "ordinary matter" enjoys "first mover" status.

In any case, I am not aware of anyone else ever suggesting that quanta are "first movers" in the same sense as free human agents.

I wasn't aware that "first mover" implied anything more than being an uncaused initiator of action.

Anyway, tell me what the necessary and sufficient criteria are for being a "first mover", and I will be happy to explain to why either

1) It is possible in a non-deterministic world (such as that described by the standard model of QM) for a physical being made of ordinary matter to be a first mover.

or

2) I do not think that first movers exist in this world.

If the result is (2), then we can move on to discussing why this is relevant to the notion of free will.

This obviously begs the question. I deny that our brains do any of this; only our minds have these capabilities, and I am aware of no good reason for thinking that the mind is somehow reducible to the brain.

One very good reason is the utter lack of evidence to indicate that anything else is involved. An even better reason is the fact that the laws of physics as we understand them are known to be extremely accurate under the conditions that obtain in the human brain. So to suggest that some violation of the laws of physics is occurring under those conditions, without any evidence whatsoever to support that claim, is the worst kind of special pleading.

It is fundamentally no different than a Christian insisting that we have no good reason for thinking that Jesus did not really rise from the dead, because it was a miracle. I'm sorry, but that is not reasonable.

I think the question you are trying to ask, is how did the universe get set in motion in the first place. Although I believe that question is beyond the scope of this discussion, I will entreat it with the answer that this line of reasoning assumes non-movement as a default state of the Universe, when in fact everything we can observe points to the opposite conclusion.

Perhaps there is no change of state in the universe, what we perceive as time and motion could be the real illusion, while the Universe remains in an unchanging state of relationships spanning the dimensions of our perception. When asking a question so grand, it is reasonable not to expect an easy answer.

I was more thinking that it might illustrate that logic is in someway dynamic. That some relationships can only be approximated and are constantly in a state of flux. Such a Universe though can't be strictly determinsitic thats all.
