Arendt The Life of the Mind
For the thinking ego and its experience, conscience that "fills a man full obstacles" is a side effect. No matter what thought-trains the thinking ego thinks through, the self that we all are must take care not to do anything that would make it impossible for the two-in-ne to be friends and live in harmony. This is what Spinoza meant by the term "aquiescence in one's self" (acquiescentia in seipso): "It can spring out of reason [reasoning]. and this contentment is the greatest joy possible." Its criterion for action will not be the usual rules, recognized by multitudes and agreed upon by society, but whether I shall be able to live with myself in peace when the time has come to think about my deeds and words. Conscience is the anticipation of the fellow who awaits you if and when you come home. p.191
