 Carneades thinks that, while the fatalist argument from bivalence fails, the fatalist argument can be successfully restated in terms of causal determinism, since causal determinism is incompatible with our actions truly being in our power (Fat. 31, LS 70G.) That is because, for our actions to be in our power, we must have the ability to make things turn out otherwise than they actually do turn out (Fat. 45), and this ability is incompatible with all things being predetermined by an interconnected chain of natural causes (Fat. 31, LS 70G). According to Carneades, human actions have a cause—the “voluntary motion of the mind”—but the way in which we exercise this power and move ourselves is not itself causally necessitated.
