 Does backward caution imply fatalism? An often advanced objection against backward causation is that if eternalism and backward causation are possible, then the future is already determined. And if it is already determined now what the future is going to be, then it does not matter what an agent will do, since everything in the future is set and done. An agent cannot do other than what the future is determined to be. Although this argument seems very appealing, it may not hold for a closer scrutiny.
