The Classical Compatibility of Free Will

AJA is a really good example of classical compatibleism. He thinks like a lot of people did in the classical period that free will requires the ability to do otherwise. If determinism is true, there aren't physically possible alternatives. So how could it be the case that I could have acted otherwise? And AR says, aha, well to say that you could have acted Otherwise is just to say something like a subjunctive counterfactual conditional. That's an analysis of what we mean when we say that an agent is able to doing otherwise.
