 Berlin did not assert that determinism was untrue, but rather that to accept it required a radical transformation of the language and concepts we use to think about human life – especially a rejection of the idea of individual moral responsibility. To praise or blame individuals, to hold them responsible, is to assume that they have some control over their actions, and could have chosen differently. If individuals are wholly determined by unalterable forces, it makes no more sense to praise or blame them for their actions than it would to blame someone for being ill, or praise someone for obeying the laws of gravity. Indeed, Berlin further suggested that acceptance of determinism – that is, the complete abandonment of the concept of human free will – would lead to the collapse of all meaningful rational activity as we know it.
