In Freedom and Science, David Cockburn does not provide a moral argument in defense of free will. Instead, the philosopher argues against the neuroscientific challenge to freedom of will, which argues that our actions are simply causal functions of uncontrollable chemicals in our brains. Drawing on an example of a man who commits murder as a result of his unknowing exposure to chemicals, Cockburn investigates whether the chemical caused or enabled his violent behavior. In the case of this man, to an ordinary observer, had the chemical not been present the man would not have killed. Moreover, since the man had no control of whether or not the chemical was in the room, it follows that he was not free to choose whether or not to murder. Cockburn complicates this logic by offering an alternative scenario. Imagine that a diabetic man is on trial for murder who frequently needs insulin in order to prevent him from falling into a coma. By random chance, a chemical he is exposed to at work has the same effect as insulin. As a result, he does not collapse …show more content…

Notably, viewing events without presuppositions is to maintain presuppositions. In this particular case, Cockburn argues that since we held assumptions, we must state precisely what would adequately show that an individual was not free. Second, he argues that our assumptions stop us from seeing the logical fallacy we are engaged in. He asserts that it does not logically follow that an individual cannot be held responsible for an action, had it not been for a certain chemical process in the brain. While we cannot stop our hearts from beating despite them being a part of us, it does not follow that we are suddenly “not responsible for what” we do. Finally, Cockburn argues that while the presence of the chemical in the second case enabled the man to kill, it obviously did not cause him to do
