The classic question of free will has changed in light of contemporary programs of accounting for moral responsibility. What once was a question of what is necessary for someone to be free, in a metaphysical sense, is now a question of what about us allows us to have the intuitions that we are morally responsible while lesser creatures are are not. This is distinctively a compatibalist program, but in light of certain indeterminacies at the sub atomic level, it has increasingly become a rising methodological approach among incompatibalist. Various accounts in the literature have emerged, each as clever as the last, but the most striking attempts of accounting for free will are those that integrate past philosophies into the methodology.
Now, all the Nietzsche people will undoubtedly point out that Nietzsche manifestly denied free will on the grounds that such a thing would require an agent to be causa sui, but this is simultaneously the beginning and the end of that discussion… Clearly, the claim is about a metaphysical free will, but that’s not what I’m concerned with. The question to be answered here is what, if anything, can Nietzsche tell us about the free will.
A Niezschean account of the modern question of free will goes something like this:
There are two main currents of thought concerning the role of reason in man’s motivational systems. The Humean account that the Passions are the sole motivator of man, and that reason is but a calculator that lets us apply our desires in the most efficient way. Second, is the Platonic model. Reason is productive in a radical and primary way. That which we value, and that which actually has value is a matter of reason. Sense reason tends toward the true and the good, the free man is motivated by reason, and reason is godly.
Somewhere in between lies a Nietzschean account, and the following question elucidates it. The question of “what one most strongly wants” can be bifucated into two finer questions. They are, what does one most value, and what does one most desire. The Humeans account claims that the latter is the only question, and the Platonic account claims that the former is the only true account.
The Nietzschean account is that they are both important questions, but freedom lies in the alignment of one with the other. Modern programs concerning the free will claim that the motivational system must come to be in line with the valuational system. That is, if what motivates us to act is not what we most desire, but what we most value, then we are free. It seems that Nietzschean accounts would be the exact opposite. The truly free man, the overman, happens when the valuational system comes to line up with the motivational system in reference to instincts, when instinct is understood as the will to power.
Notice this, the claim is not that we line our valuational system up with the instincts themselves, but we look to the instincts to tell us what our motivational system actually is. And that is the will to power. Hence, we are the most free, and experience the greatest feeling of power, when what we value is also what motivates us - The Will to Power.
This account fits in nicely with Nietzschean critiques of Christianity where we are no longer motivated directly by the will to power, but by habituation and rationalization.
