Are we really free? The question “Could I have done otherwise?” is central to the issue of free will. But because choices are forward-looking, at the time of choice there is not yet any action to do otherwise. The question makes more sense when aimed at the future: “Can I do something fundamentally unpredictable?” The answer is yes! Humans possess properties that make us capable of undecidable dynamics, meaning we are fundamentally unpredictable, and so we do have free will.
