 The rise to self-love is in fact a matter so strange that the further spread to rational benevolence is trivial by comparison: having come to be interested in, e.g., the provision of food at a time when I am not hungry, it is no great wonder that I am rationally moved by another’s real or imagined need for food as much as by my own.… And by, an extension natural to it, once its ampliative zeal has got underway, it tends to extend itself to an interest in what is interesting to anyone or everyone, and to develop a defensive dislike of whatever sets grounds to its natural expansiveness.
