“Thou shalt love thy neighbor as thyself.” 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.
