Perhaps accepting [nihilism] would make us less selfish. At any rate it would mean that self-interest was not a rational motive for action. How could it be, if there is no “self” to have any interests? If there are no such beings are myself or others, there can be no reason to put my interests above those of others. Nihilism might imply that all interests are of equal value. We might find that liberating.
