I'll provide some definitions, from Oxford:

individual: "single; separate"; "of or for a particular person"; "a single human being as distinct from a group, class, or family"

free will: "the power of acting without the constraint of necessity or fate; the ability to act at one's own discretion"

From these definitions, we must question whether a single human, Homo Sapiens, can possibly act at their own discretion, without fate or necessity as the cause.

The history of studying free-will is extremely lengthy, everything non-biological that can be said has likely been said. We've been blessed by modern science to have a lot more understanding of organisms and neurology, so we know the "inner workings" better than Descartes or Locke or any of the old Christian theorists.

Yeah, but we're a bunch of unionized atoms. They all vote on what I should do and then I execute their will by going in the kitchen and making spaghetti or whatever.
