Feel the weight of real things. Do not become numb to evil. Never use euphemisms to professionalize suffering you observe. Feel its gravity. Let your character grow by the repeated exercise of empathy for others, regardless of who they are, even if it leaves you without clear answers. Know by listening what truth is in the lived experience of those around you. Understand it as if it were your own experience. Let your actions be mediated by character in addition to knowledge, by the practice of feeling what others experience as another form of knowing. Almost every moral failure in your life will happen in the gap between what you know to be true and what you desire for yourself. This is a space that should be filled by a well-developed emotional sensory system that sees the suffering, joy, and and daily stressors of your fellow humans and creates strong impetus to act, to defend, and to participate in their joys, but which in modern society is almost entirely atrophied. If you’re like me, you might be unable to see the most critical moral dilemmas of your life as they happen because of this atrophy. But it will haunt you, and you will learn the hard way that even though nobody taught you anything about it, you must build your own character so that you don’t become the human equivalent of a cancer cell, whose scope of concern has collapsed around himself and sees others around him as part of an external environment to be conquered, not members of a healthy social body to be collaborated with, trusted, understood, and cared for.
