Full Idea
With Stoics, and in its wake, we get an enormous expansion of what counts as being forced [biazesthai] or compelled or made to do something, and correspondingly an enormous contraction of what counts as an action of one's own.

A Reaction
The key idea seems to be setting the bar higher for being in control, which eventually leads to the idea of free will. Frede says this does not contract responsibility, because what controls us can be our own fault.
