Full Idea
The ordinary man believes himself to be free ...to act as he wants, but this arbitrariness entails that he is not free, because what it is that he wills is not intrinsic to self-determining activity, ...and depends on a given content and material.
Gist of Idea
People assume they are free, but the options available are not under their control

A Reaction
[a bit compressed] I take this to be an extraordinarily influential idea (especially for Marx). Hitherto philosophers just wanted some vague metaphysical 'free will', making moral responsibility and pure reason possible. But who controls the options?
