Shall I eat and drink only that I may hunger and thirst and eat and drink again, till the grave which is open beneath my feet shall swallow me up, and I myself become the food of worms? Shall I beget beings like myself, that they too may eat and drink and die, and leave behind them beings like themselves to do the same that I have done? To what purpose this ever-revolving circle, this ceaseless and unvarying round, in which all things appear only to pass away, and pass away only that they may re-appear unaltered; — this monster continually devouring itself that it may again bring itself forth, and bringing itself forth only that it may again devour itself? This can never be the vocation of my being, and of all being. There must be something which exists because it has come into existence; and now endures, and cannot again re-appear, having once become such as it is. And this element of permanent endurance must be produced amid the vicissitudes of the transitory and perishable, maintain itself there, and be borne onwards, pure and inviolate, upon the waves of time.
