June 9, 1870.--At bottom, everything depends upon the presence or absence of one single element in the soul--hope. All the activity of man, all his efforts and all his enterprises, presuppose a hope in him of attaining an end. Once kill this hope and his movements become senseless, spasmodic, and convulsive, like those of some one falling from a height. To struggle with the inevitable has something childish in it. To implore the law of gravitation to suspend its action would no doubt be a grotesque prayer. Very well! but when a man loses faith in the efficacy of his efforts, when he says to himself, “You are incapable of realizing your ideal; happiness is a chimera, progress is an illusion, the passion for perfection is a snare; and supposing all your ambitions were gratified, everything would still be vanity,” then he comes to see that a little blindness is necessary if life is to be carried on, and that illusion is the universal spring of movement. Complete disillusion would mean absolute immobility. He who has deciphered the secret and read the riddle of finite life escapes from the great wheel of existence; he has left the world of the living--he is already dead. Is this the meaning of the old belief that to raise the veil of Isis or to behold God face to face brought destruction upon the rash mortal who attempted it? Egypt and Judea had recorded the fact, Buddha gave the key to it; the individual life is a nothing ignorant of itself, and as soon as this nothing knows itself, individual life is abolished in principle. For as soon as the illusion vanishes, Nothingness resumes its eternal sway, the suffering of life is over, error has disappeared, time and form have ceased to be for this enfranchised individuality; the colored air-bubble has burst in the infinite space, and the misery of thought has sunk to rest in the changeless repose of all-embracing Nothing. The absolute, if it were spirit, would still be activity, and it is activity, the daughter of desire, which is incompatible with the absolute. The absolute, then, must be the zero of all determination, and the only manner of being suited to it is Non-being.
