 If the intuitions to which the No Forking Paths argument appeals nevertheless continue to engage us, it is because we think that our range of possible choices is constrained by two factors: the laws and the past. We can’t change or break the laws; we can’t causally affect the past. (Even if backwards causation is logically possible, it is not within our power.) These beliefs—about the laws and the past—are the basis of the most influential contemporary argument for incompatibilism: the Consequence argument. More of this later.
