 In contrast, the eternalist could argue that the reason why it is true today that an agent will visit her parents tomorrow is because the agent makes a decision that causally determines her visit before she goes to see them. If the agent makes the opposite decision tomorrow, it will be true today that she will not visit her parents. Whatever she chooses tomorrow, it will be her decision which makes it true today that she is going to see her parents. The outcome of her decision tomorrow is determinate not because the present truth value fixes her decision but because her future outcome fixes the present truth value. (Nor is it the case that the outcome of her decision causally determines her previous decision.) Thus, the eternalist may argue that even though the future is determinate, it does not exclude people from having free will. If people have free will, the argument goes, the fact that the outcome of their future decision is determinate with respect to the past does not affect their ability to choose freely.
