 If one were truly indifferent one simply would not choose. But once there is a will to choose, the cascade of causes that leads to action will determine the choice one way or the other. What Collins means by “doing as we will” is what we do consequent to willing. Here again, he finds no freedom from necessity. We do what we have willed unless some external impediment or intervening cause hinders us from doing so. Finally, he compares the actions of animals to those of men. He claims that while animals are supposed to be necessary agents and humans free agents, there is no perceivable difference between their actions that would allow us to make this distinction (Collins 1717: 53–57 [1976: 80–82]).
