 These subjects are mostly addressed in the fields of cognitive science, neuroscience (e.g.the neuroscience of free will) and philosophy of mind, though some evolutionary biologists and theoretical physicists have also made several allusions to the subject.Reductionistic and eliminative materialistic approaches, for example the Multiple Drafts Model, hold that consciousness can be wholly explained by neuroscience through the workings of the brain and its neurons, thus adhering to biological naturalism.
