Full Idea
We have a power to suspend the prosecution of this or that desire; as everyone daily may experiment in himself. This seems to me the source of all liberty, ..which is (as I think improperly) call'd 'free will'.
Gist of Idea
We are free to decide not to follow our desires

A Reaction
This strikes me as a feeble defence of free will, since we have no idea of the origin of the decision not to act according to some desire. I see no sign of free will in introspection, despite what some people claim.
