@victorgijsbers he's not expressing it as an ontological fact of all beings or anything, but only for himself — he's speaking personally. The point he is making is simply that caring only about your own causes and values and desires (in the sense of the things you *actually do* care about, desire, or value, not things that simply request those things from you) doesn't necessarily have to cut you off from everyone else. Also, he goes on in the next paragraphs to caveat this a little, saying that the fact that he cares about everyone's suffering and joy sort of by default doesn't mean there aren't exceptions to this, because there is no fact of his necessarily loving everyone or any commandment.
