Now you love yourself suitably when you love God better than yourself. What, then, you aim at in yourself you must aim at in your neighbor, namely, that he may love God with a perfect affection. For you do not love him as yourself, unless you try to draw him to that good which you are yourself pursuing. For this is the one good which has room for all to pursue it along with thee. From this precept proceed the duties of human society, in which it is hard to keep from error. But the first thing to aim at is, that we should be benevolent, that is, that we cherish no malice and no evil design against another. For man is the nearest neighbor of man.

-St. Augustine of Hippo
