Lewis and Kane both give their definitions in the predicative form. If you get Kane, you should be able to get Lewis. If you add "
x is determined when…" to the beginning of the Lewis quote it might help you see how similar Kane and Lewis's definitions are. Kane just gives examples for Lewis's
H variable and leaves out the
L variable (since I don't think it is relevant in some forms of determinism).
long-winded way of saying "every event has a cause"? I think maybe yes.
Well, not really "long-winded"… Kane was giving a definition and, nowadays, virtually every philosopher gives these types of predicative definitions since they do make it clearer whether a particular instance fits into that concept or term.
There
might not be anything wrong with saying "every event has a cause," except there are many different types of causes and many different causal theories. If we are going to capture various forms of determinism, like theological and scientific determinism, under the phrase "cause" then our concept of "cause" will have to be rather abstract… in which case I think Kane's definition will actually be the clearer one. In fact you might end up having to go back and define cause in such a way that it ends up looking very much like something Kane said: a sufficient condition for the occurrence of an event!
I wasn't trying to say all subsequent events aren't determined. Just saying that, if God had no cause, than the world is indeterminate. Things can still be determined within an indeterminate universe, but not all events need have a cause, basically.
I don't think it's very clear to use determinism/indeterminism in this way. If you said to someone "the universe (or world) is indeterminate" they would probably be very surprised to hear you admit that "this may mean all creaturely actions are determined." My guess is that this wouldn't sound like indeterminism to them and if you simply stipulate that it is, like I said earlier, I don't think they would find it very relevant.
(Besides, I don't think the example of God not having a cause works. You mentioned God not coming into being, but this simply means that the concept of causation in the sense of "beginning to exist" doesn't properly apply to God. In other words, it's just a category error to ask "what caused God?" and I don't see that it has any significance to in/determinism since it's not clear why in/determinism should depend on that type of causality. God's coming into being wasn't an event at all, so trying to fit that non-event into the category of "events-of-coming-into-being" doesn't make sense.)
It seemed like you were saying soft-determinism means the same thing: that one event wasn't determined, but the other events are.
No, some soft-determinists, like Daniel Dennett, don't think any events were indetermined (and he's an atheist so he certainly wouldn't care about the God not coming into existence thing).
Would that be a religious view, or a philosophical view? Because I do remember being taught that one could argue, indeterminism or determinism, there is no free will. It was taught from a philosophical point of view, though, and not a religious stand-point.
I'm not sure how you would distinguish those two. Some Buddhists don't believe in free will and I guess you could say that's a point of their religious dogma, but at the same time it is unavoidably a statement about metaphysics, which is a field of philosophy.
So it can be both… but I guess it depends on how or if you want to distinguish them. For example, I've heard it said that something is religious if it is grounded in revelation and something is philosophic if grounded unaided reason. But I don't find that too helpful.
My point was that PAP helps to determine if a conclusion to an argument is valid or not.
No... The Principle of Alternative Possibilities is a technical term that refers to a very specific thing and it seems like you are getting hung up on the term "alternative possibilities" in a generic sense of something like "possible world scenarios". But this might be my fault since I never actually defined PAP.
PAP states that persons can't be morally blameworthy (or praiseworthy) unless they could have done otherwise (under the exact same conditions). It seems obvious enough that we can have possible world scenarios and hypotheticals without saying that these occurred under the exact same conditions, without saying that they could have been actual, and without saying they are necessary to a thing being morally blameworthy/praiseworthy.
...PAP is used here, then, to prove the conclusion is true, because no other imagined conclusion could ever end up being true.
The example you gave there didn't employ PAP.
How does an error not count as free will?
Because of the way free will is typically defined. For example, all libertarians say that an agent must have control over his actions/choices if he is to be free (compatibilists agree to a point, but distinguish between types of control (e.g., regulative and guidance)). But an action that is a result of some error or mistake is not within the control of the agent (all things being equal). For instance, people with Tourette's have a type of "brain-error" and so we don't hold them responsible for their random cursing and we don't consider their random cursing to be a free act of the will.
Of course we can imagine examples in which "accidents" are morally blameworthy, but this isn't relevant to the type of example (or "error") you gave.
Or there is the argument that God is outside of time, so He knows everything because it has already happened, or something to that effect. I'm not quite sure how the science of being outside of time works.
If God is outside of time, and one assumes that is something similar to being in the future (placing us in the past), then it is not that he foreknew what we were going to do. He is just looking back on what we have already done. That doesn't take away free will any more than me looking back on what I did yesterday takes away my free will of what I did yesterday.
This is commonly called the "Boethian" objection or solution in the relevant literature, presumably because Boethius (in "The Consolation of Philosophy") was the first to suggest it. I don't think it holds any water, but insofar as it deals with time it gets into some complicated issues.
First of all, on some theories of time, for instance a relational A-theory of time, it doesn't even make sense to say God is "outside" of time, unless you are some sort of a deist.
But if God is outside of time and sees everything as present, then how does he know tensed propositions like "It is now no longer raining" or "yesterday I went to the mall"? If God doesn't know tensed propositions as such, then are they objectively true for us? Are the tenseless propositions true for God? How can they both be true? And if they are false for us (I assume they would not be false for God) then we have to posit a B-theory of time which has it's own difficulties!
So I'm not convinced it makes any sense to say God is "outside" of time. I have no problem with saying God is eternal, and I think we have good reasons for believing that, but I see no good reason to say God is "outside" of time.
Second, you say "That doesn't take away free will"… but this statement is vague. The foreknowledge argument is not intended to show that we don't have free will, unless you think free will requires an indeterminist state of affairs. The foreknowledge is immediately concerned with demonstrating the necessity (or "determinism") of events.
If you think free will requires indeterminism, you will think the foreknowledge argument shows we don't have free will. If you think free will is compatible with determinism , you won't think it shows we don't have free will.
Third, you talk about past states of affairs and free will. But virtually everyone agrees that the past is necessary (accidentally or "necessity per accidens" as its often called).
You can't change the past (unless, I suppose, you posit a B-theory of time in which "the past" is just a subjective term anyway… but I'm not sure you could change "the past" there either). But if God sees all events as past events, then it seems that
all events are just as necessary as all past events! So you still don't have PAP and you still end up with a type of determinism.
Fourth, the Bible speaks of God knowing things ahead of time. Why would we reject that? For instance, Jesus told Peter that at some future time he would deny Jesus three times. Whether or not this was actually foreknown by God (or whether God knew it as a present event or a past event) is irrelevant since at some time, t1, it was known that at some future time, t2, he would deny Jesus three times. Jesus could not have been mistaken. Ergo,
Peter's denial of Jesus was still a necessary event, regardless of how God knew the event.
To summarize, I see no value at all in positing God being outside of time. It doesn't seem to make any sense and it doesn't seem to solve any problem (i.e. the foreknowledge --> determinism problem) and in fact it raises several problems (does God know tensed propositions? does it require a B-theory of time? what do we do with Scripture that speak of God's
foreknowledge?). It looks useless to me.
That's like the argument Christians make to atheists when they say "It's not my problem you can't disprove the existence of God." It's not really a fair argument.
No one is asking the libertarians to disprove something. They postulate PAP… how is the fact that they can't provide empirical evidence of their claim unfair?
It looks like some steps in that reasoning are missing. Maybe if people explained the second premise better it wouldn't be such a bad proof. I don't know, though. I'll just agree with you that it is a bad proof.
To rework it into a clearer transcendental form it might look more like this: free will presupposes PAP. Free will. Therefore, PAP.
There are no steps missing, but you might think the first premise is unconvincing without some support.
