Why the concept of “free-will” is nonsense: A microessay.
Before making the argument alluded to in the title of this piece, it is necessary to distinguish “legalistic” from “metaphysical” free-will. Legalistic free-will refers to the kind of freedom that a person can be granted by law, or, by virtue of the fact that he/she is not physically confined, restrained, or forced to act under coercion. There’s little to debate about “free-will” (or “freedom”) in this sense.
Metaphysical free-will is the kind that can only be granted by God, or, alternatively, by the act of disobedience exhibited by Adam and Eve in the Garden of Eden, which is rather difficult to explain if Adam and Eve did not already possess the freedom to disobey. There is a great deal that can be debated about “free-will” in this sense, starting with whether or not the concept makes sense.
What is free-will? That is the problem. It is impossible to describe what free-will is or how it works, except in supernatural terms. Why? Because metaphysical free-will requires that we (human beings) cause actions or events to occur without ourselves having been caused to initiate those actions or events. In effect, we (human beings) must be uncaused causes or unmoved movers.
Why would anyone want to entertain such a flagrant violation of the second law of thermodynamics? There are 2 reasons, the first of which pertains to the assignment of responsibility, guilt, or blame. The underlying assumption is that whatever causes action A is responsible for action A, so, if you caused it, then you are responsible, guilty, or blameworthy for A. (The reasoning works the same way with regard to moral credit or praiseworthiness, but that is neither here nor there.) The second reason why people are tempted to disregard the second law of thermodynamics pertains to getting God off the hook for the existence of evil in His creation; however, I shall ignore this metaphysical motivation for the moment.
Suppose that, instead of causing action A freely, you were compelled to cause it by influences outside your knowledge or control; suppose you were caused to cause action A. Suppose you were caused by your upbringing, your social milieu, a disease, a malfunction within your brain, etc. In that case, you would NOT be responsible for action A, because you had not caused it. However, if we are to accept the second law of thermodynamics as true, then ALL actions are like this. Everything you have ever thought, said, felt, or done has been caused by something beyond yourself.
But what, then, becomes of moral responsibility? There is another way to account for this very important notion, but I have already done this elsewhere (q.v., available upon request). My purpose here is simply to show why the concept of metaphysical free-will is nonsense, or what philosophers call “incoherent.” This incoherence can be demonstrated very simply by asking, “How does free-will work?”
Assuming the second law of thermodynamics as true, and that human beings are not uncaused causes or unmoved movers (i.e., we cannot create something from nothing), then there is no possible naturalistic mechanics of such phenomena. There remains only “the” supernatural explanation; but what is the supernatural explanation?
The supernatural explanation is that, every time a human being performs a voluntary action, God performs a miracle. So, if you decide to raise your right arm and your arm goes up – it’s a miracle! There is no other means (or none I can imagine) to account for such supernatural causation. But, if correct, this explanation has two highly undesirable outcomes: 1) Every time anyone, all throughout past and future history, performs a voluntary action – it’s a miracle! But it would seem that such miracles are a dime a dozen; so cheap, in fact, that we can probably find better explanations without them. 2) If God performs a miracle with every voluntary action, then God is responsible for every voluntary action which does evil, like premeditated homicide. The second motivation for disregarding the second law of thermodynamics – to get God off the hook for the existence of evil in His creation – fails, by the way, rather miserably.
Unless, and until, some great thinker can provide us with what we might call “a mechanics of free-will,” then we are well advised to disregard the concept of free-will in its metaphysical sense. At the same time, I also believe that we should fight to the death to defend free-will in its legalistic sense.
