From Friederich Nietzsche's Twilight of the Idols (Commonplace Book)

Emerson has that gracious and clever cheerfulness which discourages all seriousness; he simply does not know how old he is already and how young he is going to be; he could say of himself, quoting Lope de Vega: "I am my own heir." His spirit always finds reasons for being satisfied and even grateful; and at times he touches on the cheerful transcendence of the worthy gentleman who returned from the amorous rendezvous, "as if he had accomplished his mission." "Though the power is lacking," he said gratefully, "the lust nevertheless is praiseworthy."
