There is no free will

Free will is an illusion. The illusion itself is the foundation of our society, and the foundation which allows us to carry on as individuals. Society is founded upon the presupposition that we have free will, and even goes out of its way to defend that; acknowledging, for example, situations in which our actions are not under our control, be it influenced chemically through some form of intoxication, or a more general mental disorder, giving rise to leniency when laws are broken under these situations. Maybe a punishment is less severe. Maybe insanity is pleaded, leading to incarceration in a mental institution.
