Philosophers have articulated six notions of human freedom. Four are metaphysical. According to one, a man acts freely when he is doing what he wants to ; according to the second, he acts freely when he is not being compelled by outside forces ; according to the third, he acts freely when the prior state of the universe was not a sufficient cause of what he is doing; according to the fourth, he acts freely when he, not any preceding event, (...) is the cause of what he is doing. The third and fourth theories may be called “indeterministic freedom” and “the agency theory,” named only to be rejected. I reject indeterminism out of agreement with a long tradition which holds that there is no reason to think that human actions are ever undetermined, and an undetermined human action would not be “free” in any sense in which we desire our actions to be free and believe that they are in fact free. To appreciate, reflect that agents should control and be accountable for “free” actions. Now, we control an event by assembling or obstructing its sufficient conditions; merefore, an event without sufficient conditions, a random event which just happens, would lie beyond human control and, hence, the sphere of human freedom. Similarly, a man is no more responsible for what happens independently of his choices – and an event without sufficient conditions cannot have a choice as a sufficient condition – than he is responsible for the behavior of a roulette wheel.
