The condition of all who are preoccupied is wretched, but most wretched is the condition of those who labor at preoccupations that are not even their own, who regulate their sleep by that of another, their walk by the pace of another, who are under orders in case of the freest things in the world-loving and hating. If these wish to know how short their life is, let them reflect how small a part of it is their own.
