" Official criticism participates in the pitiable fate of Proktophantasmist and his lamentation in the Walpurgis-night: "You still are here? Nay, 'tis a thing unheard! Vanish at once ! We've said the enlightening word." Such criticism has omitted to take to heart the truth that all that exists has sufficient right to its existence: no less is it with psychoanalysis. "
