 Here are two difficulties for Price’s claim that understanding the light in which someone saw their action would enable us to predict what they would do. First, it is questionable whether weak-willed actions are fully intelligible. Although the agent has reasons for what he does, they do not explain his making the worse rather than the better choice. Second, if we are genuinely able to form and change our characters through our choices, then there must be occasions on which we act out of character. If there is real freedom of choice even God might not know with complete certainty what we will do (though this view, known as Open Theism, might be unpalatable to Price).
