THE MAN OF GENIUS.

PART I.
THE CHARACTERISTICS OF GENIUS.

CHAPTER I.
History of the Problem.

Aristotle—Plato—Democritus—Felix Plater—Pascal—Diderot—Modern writers on genius.

IT is a sad mission to cut through and destroy with the scissors of analysis the delicate and iridescent veils with which our proud mediocrity clothes itself. Very terrible is the religion of truth. The physiologist is not afraid to reduce love to a play of stamens and pistils, and thought to a molecular movement. Even genius, the one human power before which we may bow the knee without shame, has been classed by not a few alienists as on the confines of criminality, one of the teratologic forms of the human mind, a variety of insanity.

This impious profanation is not, however, altogether the work of doctors, nor is it the fruit of modern scepticism. The great Aristotle, once the father, and still the friend, of philosophers, observed that, under the influence of congestion of the head, “many persons become poets, prophets, and sybils, and, like Marcus the Syracusan, are pretty good poets while they are maniacal; but when cured can no longer write verse.”[5] And again, “Men illustrious in poetry, politics, and arts, have often been melancholic and mad, like Ajax, or misanthropic, like Bellerophon. Even in modern times such characters have been noted in Socrates, Empedocles, Plato, and in many others, especially poets.”[6]
