'Happiness lies in living for others. That is evident. The desire for happiness is innate in every man; therefore it is legitimate. When trying to satisfy it selfishly—that is, by seeking for oneself riches, fame, comforts, or love—it may happen that circumstances arise which make it impossible to satisfy these desires. It follows that it is these desires that are illegitimate, but not the need for happiness. But what desires can always be satisfied despite external circumstances? What are they? Love, self-sacrifice.'
