The Dilbert comic at the beginning does not acknowledge that the laws of physics (QM, Boltzmann distributions, etc) are not deterministic. So it is entirely reasonable to say that the free will exists and obeys the “laws” of physics in the brain. Consider Oxford professor Roger Penrose’s statement:
“With the possibility that quantum effects might indeed trigger much larger activities within the brain, …] quantum indeterminacy might be what provides an opening for the mind to influence the physical brain. Here, a dualistic viewpoint would be likely to be adopted, either explicitly or implicitly. Perhaps the ‘free will’ of an ‘external mind’ might be able to influence the quantum choices that actually result from such non-deterministic processes. On this view, it is presumably through the action of quantum theory’s [wave-function collapse] that the dualist’s “mind-stuff” would have its influence on the behaviour of the brain.” (Shadows of Mind, page 349)
It is entirely reasonable to say, as the scholastics did, that the soul is the act of the body, imposing form on the non-deterministic quantum wavefunctions (or potencies, to use Heisenberg’s term). More specifically, since neurons fire spontaneously (
article), due to quantum properties of sodium channels (
article), these firings may combine in inhibitory and excitatory patterns to give rise to many of the higher functions of animals (
article). In this last article, neuroscientists have come face to face with the bird’s “sensitive soul,” as it is known in Thomistic philosophy, but these researchers have denied its existence, rather attributing the spontaneity to ‘randomness’ because ‘birds don’t talk.’ Truly, we are free, but these folks would rather call it random to deny their responsibility for their actions.
