“One of Stoics’ most fundamental attitudes: the delimitation of our own sphere of liberty as an impregnable islet of autonomy, in the midst of the vast river of events and Destiny. What depends on us are the acts of our soul, because we can freely choose them. We can judge or not judge or judge in whatever manner we please; we can desire or not desire; will or not will.”
- Pierre Hadot, “The Inner Citadel”
The challenge is to understand your sphere of liberty.
Where the border lies between the things you control and the things you do not.
Understand where it is and never cross it.
This is the path to freedom.
