The problem of free will arises from ordinary, commonsense reflection. Shaun Nichols examines these ordinary attitudes from a naturalistic perspective. He offers a psychological account of the origins of the problem of free will. According to his account the problem arises because of two naturally emerging ways of thinking about ourselves and the world, one of which makes determinism plausible while the other makes determinism implausible. Although contemporary cognitive science does not settle whether choices are determined, Nichols argues that our belief in indeterminist choice is grounded in faulty inference and should be regarded as unjustified. However, even if our belief in indeterminist choice is false, it's a further substantive question whether that means that free will doesn't exist. Nichols argues that, because of the flexibility of reference, there is no single answer to whether free will exists. In some contexts, it will be true to say 'free will exists'
