I'd like to point out first that none of you have offered any actual arguments for why determinism is correct. You have merely assumed that to be the case. I have responded with arguments against determinism and arguments for free will.
The knowledge exists, but gaining enough knowledge to predict someone somewhat accurately is virtually impossible.
Yup, that's why I said humans are unpredictable.
Yeah, just because SK can't predict your finger snapping, doesn't mean it wouldn't be possible to someone who had knowledge of everything that had happened up to that point and the intellect to comprehend it. That's all "determinism" (that's a good word; just learned it) implies.
I'd like to see someone think of the chain of events that caused me to snap my fingers with one hand rather than the other, or to do that rather than stick my tongue out or whatever other random action I could choose.
Pure determinism is foolish because humans have a dynamic psych, yet another abstract concept we cannot prove, yet one we can theorise co-exists with a deterministic mind.
When we predict a random action we cannot pinpoint exactly what action it was. Did you snap your right hand? Your left? You thumb and middle finger? Did you hold your pointer finger to your middle finger?
Determinism is not absolute, random actions are unpredictable by their very nature, and made possible because of the human random psych.
I can predict, however, that you will post again in this argument.
Humans aren't completely unpredictable. I can predict that you will use a bathroom (or should I say "dunny"?) at some point in the next 48 hours. But you can't predict exactly what humans will do, which is what determinism would imply.
Good prediction. Though I think it is less an argument, more a socratic discussion.
Even "random actions" can be accounted for in literal and specific terms. For example, if a man commits a random act, that act is still the result of very minute and intricate physiological responses to biochemical reactions. As I implied earlier, the specific mechanism by which determinism occurs is beyond human comprehension, but that doesn't mean it can't exist in an absolute sense.
You claim that the act is a direct result of biochemical reactions. You don't have much to back up this statement, since we are all going through similar biochemical reactions all the time, yet we are not committing the same actions.
We don't know all of the factors that influence a dice roll, but we know they existed unless we believe that god reached out and touched it or whatever. No, we can't prove that there's no randomness in human whatever, but it seems more reasonable to assume than the alternative. I think. I mean, can we prove anything? *stonerface*
I do like your posts here though they're really smart and stuff.
We assume that given knowledge of the exact force, etc with which you throw a die that you would be able to predict the outcome. Once again though, there is no reason to assume this for humans, and indeed you would need a LOT more hidden variables to account for this.
Recall also that physicists have rejected the "hidden variable" interpretation of quantum mechanics and accepted that there are things that are unpredictable in some sense.
That's what I said, that determinism may very well be acceptable in the future, but not right now.
Determinism implies a distinct cause for everything, so a pure determinism should disregard concepts for which a distinct cause cannot be found, such as pure determinism.
A less absolute form of determinism is viable, and is my stance.
ballin, your argument assumes free will. Free will is not observable, every 'free' action can be attributed to determinism as well. Additionally, there is neurochemical evidence for a deterministic fashion. We have linked causality between neurochemicals and behaviour, you cannot possibly say it is your free will that causes the neurochemical secretion.
Yes, every free action could be attributed to determinism ... if you make a TON of assumptions about hidden variables. I do think free will can cause neurochemical secretion in some cases, but regardless I agree that the brain and body have an impact on the mind, just as the mind has an impact on the body. But that still does not mean that the mind is 100% controlled by chemicals.
