Our errors of valuation continue with respect to ourselves and others. We overlook faults in ourselves but find them easily in those around us. Recognizing this is an encouragement to forgiveness. What another has done that annoys you is probably no worse than what you have done on another day. But the point is also subtler: we condemn in others precisely what we detest but cannot see in ourselves; we project our faults onto them. So the Stoic works hard for self-knowledge and makes unhesitant confessions of weakness.
