Abstract

The Consequence Argument is one of the leading arguments for the incompatibility of causal determinism and free will in the sense of freedom to do otherwise. Thus, it challenges “classical compatibilism” of the sort defended by many philosophers, such as Hume, Schlick, Ayer, Lehrer, Perry, Lewis, Vihvelin, et, al. David Lewis has offered what has become the most influential response: local-miracle compatibilism. I present a critique of this kind of response to the Consequence Argument. My critique shows that, although Lewis-style local-miracle compatibilism may effectively address some versions of the Consequence Argument, it does not succeed in refuting others. My critique consists, in large part, in arguing for a new reconstruction of the principle of the fixity of the past - a principle that played a crucial role in the history of the debate and that has, in one form or another, been employed by many important historical figures. I will also show why Lewis’s famous views about our powers in time-travel are false.
