If what distinguishes being is the act, and what characterizes the act is the choice, it is necessary to repeat a thousand times that the individual always becomes the choices he makes, and that wisdom comes down to knowing how to choose. The problem is that choice, as a unifying element, is less a decision than a perennial practice, so that without this continuity, it would fall apart and even become null and void. Choosing, therefore, involves deciding and sticking to the decision.
