Begin with the section we didn"t read of hume: Incompatibilism: determinism= no free will: fatalism: everything is decided from all eternity, libertarianism: my will is an absolute cause (determinism leave us wiggle room to exercise free will) Compatibilism: determinism is not only compatible with free will, but required by it. Kant"s view: determinism can"t be denied yet libertarian free will is presupposed by agency. We think determinism isn"t compatible with free will because we haven"t defined our terms. The libertarian interpretation is simply based on an illusion. Our notion of free will is linked to our notions of moral and personal responsibility (we don"t hold someone responsible for something they had no control over) The only meaningful freedom is from interference or compulsion from outside me: So the opposite of freedom is constraint, not determinism. But the opposite of necessity is chance! A free act cant be the same as a random one.
