said: Nullum magnum ingenium sine mixtura dementiæ fuit. Plato expresses it in the figure of the dark cave, referred to above (De Rep. 7), when he says: "Those who, outside the cave, have seen the true sunlight and the things that have true being (Ideas), cannot afterwards see properly down in the cave, because their eyes are not accustomed to the darkness; they cannot distinguish the shadows, and are jeered at for their mistakes by those who have never left the cave and its shadows." In the "Phædrus" also (p. 317), he distinctly says that there can be no true poet without a certain madness; in fact, (p. 327), that every one appears mad who recognises the eternal Ideas in fleeting things. Cicero also quotes: Negat enim sine furore, Democritus, quemquam poetam magnum esse posse; quod idem dicit Plato (De Divin., i 37). And, lastly, Pope says—
"Great wits to madness sure are near allied,
And thin partitions do their bounds divide."
Especially instructive in this respect is Goethe's "Torquato Tasso," in which he shows us not only the suffering, the martyrdom of genius as such, but also how it constantly passes into madness. Finally, the fact of the direct connection of genius and madness is established by the biographies of great men of genius, such as Rousseau, Byron, and Alfieri, and by anecdotes from the lives of others. On the other hand, I must mention that, by a diligent search in lunatic asylums, I have found individual cases of patients who were unquestionably endowed with great talents, and whose genius distinctly appeared through their madness, which, however, had completely gained the upper hand. Now this cannot be ascribed to chance, for on the one hand the number of mad persons is relatively very small, and on the other hand a person of genius is a phenomenon which is rare beyond all ordinary estimation, and only appears in nature as the greatest exception. It will be sufficient to convince us of this if we compare the
