Brief Thoughts On Free Will (and no this has nothing to do with Cyber Nations)

I think when considering the existence of free will we need to distinguish between two radically different senses of the word 'cause', with corresponding distinctions between different senses of 'determinism'. The causes of human actions are fundamentally different from the causes of non-human actions. For example, when we assess all the causes of an explosion, it becomes impossible for any power in the universe to prevent that explosion. On the other hand, if you're given sufficient cause to celebrate, that does not necessitate your resulting celebration. It follows from this that every movement of human organisms cannot be attributed to necessitating physical causes.

These two different senses of causation can be distinguished using Hume's terminology of moral and physical causes. If we describe some non-human event, such as an eclipse of the sun, then we employ the word 'cause' in a sense implying both physical necessity and physical impossibility: what happened was physically necessary and anything else was, in the circumstances, physically impossible. But in the other sense of the word 'cause', the sense in which we attribute motives to human actions, this is not the case. Suppose, for example, that I were to deliver some sort of good news to you. If you choose to respond to the news by celebrating, you may quite properly describe my action as the cause of your celebration. But I did not truly cause your celebration, it was not necessary and unavoidable. Perhaps you might have refrained from celebrating, because we were, say, in a library at the time. In other words, my news may have caused you to say “hooray!” but you might have cried “whoopee!” instead. To adapt a famous phrase of the philosopher-mathematician Gottfriend Leibniz, causes of this second, motivating sort “incline but do not necessitate.”

(credit to Antony Flew, whose ideas these are)

Does anyone have a refutation? This appears to me to blow the reductionist arguments out of the water.

That doesn't refute a reductionist argument at all. Whether you say hooray versus whoopee is still determined by your biology, history and circumstance. You may argue that there could be a degree of randomness based on relative probabilities of the activation of any given neural pathway, but it still can't properly be termed a choice.

Either your actions have causes behind them or they are random. Allow me to illustrate:

You can pick a red pen with black ink or a blue pen with black ink. The only difference is color.

Now, either you picked the red one because you associate red with good things, are biologically predisposed to like red, have a bad association with blue, whatever, or else there was a mental coin toss and the selection was completely random.

The first scenario is the one where "you" have control. Your personality was formed by things outside your control which determines your preferences, observations, biases and so forth, but it's still you making the choice based on who you are. Yes, it's determinism, but the other option is that there is an element of randomness, which just means the actions are unpredictae, not that there is a nebulous concept of non-deterministic free will.

I'm not sure why people think "if my actions can be acccurately predicted it means I was forced to make the decision no matter what I wanted." What you want is deterministic. If I handed you a bowl of ice cream and a bowl of dirt and told you to eat one or the other, I could accurately predict that you would not eat the dirt. There is a small potenntial for experimental bias in that you may eat the dirt just to prove that you have free will, but if I knew ahead of time what your personality was like, I could accurately predict that as well.
