When an effort fails, one declares bitterly that he has lost time and wasted his powers. The failure condemns that whole part of ourselves which we had engaged in the effort. It was to escape this dilemma that the Stoics preached indifference. We could indeed assert our freedom against all constraint if we agreed to renounce the particularity of our projects. If a door refuses to open, let us accept not opening it and there we are free. But by doing that, one manages only to save an abstract notion of freedom. It is emptied of all content and all truth.
