Opposition to each other is contrary to nature

Say thus to thyself every morning: to day I may have to do with some intermeddler in other mens affairs, with an ungrateful man; an insolent, or a crafty, or an envious, or an unsociable selfish man. These bad qualities have befallen them through their ignorance of what things are truly good or evil. But I have fully comprehended the nature of good, as * only what is beautiful and honourable; and of evil, that it is always deformed and shameful; and the nature of those persons too who mistake their aim; that they are my kinsmen, by partaking, not of the same blood or seed, but of the same intelligent divine part; and that I cannot be hurt by any of them, since none of them can involve me in any thing dishonourable or deformed. I cannot be angry at my kinsmen, or hate them. We were formed by nature for mutual assistance, as the two feet, the hands, the eyelids, the upper and lower rows of teeth. Opposition to each other is contrary to nature: All anger and aversion is an opposition.
