Can physics and neuroscience allow for free will?

Sammanfattning

While most of us feel we make decisions and can act out of free will, science seems to say we cannot. Neither deterministic laws of nature, acting in our macroscopic world, nor indeterministic quantum processes at microscopic levels, appear to allow for any free will. In addition, psychophysical experiments of voluntary actions by Libet and others seem to indicate that the brain decides our actions up to seconds before we are aware that we make a decision to act. All of these reasons have been taken as arguments for free will being an illusion. Here, I will discuss some of the perceived problems with free will, and how alternative interpretations of theories and experiments may lead to a different conclusion regarding the existence of free will. I will also argue that contemporary physics is insufficient for dealing with the behavior of complex biological systems, and in particular consciousness and agency. I conclude that, in order to allow for consciousness and free will, science needs to be extended beyond chance and necessity, which currently are the only models of explanation science can provide.
