Note 509 — OF IDIOTS AND LUNATICS.

There frequently exists an illusion as to particular things, to which, says Dr. Male, men of genius are sometimes subject, which leads them to indulge eccentric whimsies and extravagant fancies, whilst on every other subject their perception is clear, and their conclusions correct; instances of this kind abound in every treatise on insanity, and may be traced from the earliest period of history. Pythagoras believed that he had lived in prior ages, and inhabited different bodies, and that in the shape of Euphorbus he had assisted in the siege of Troy. Tasso fancied himself to be visited by a familiar spirit, with whom he conversed aloud (Hoole’s Life of Tasso). The hero of the celebrated romance of Cervantes, exhibits a well-drawn picture of this species of insanity; and although in a less attractive costume, how frequently do we recognise Don Quixote in every rank and description of society? If, says a celebrated writer, the circle in which this absurdity revolves is so very small as to touch nobody, a man is only what is then called singular in that respect; but if its orbit is extended so as to run foul of other people, he is then called a madman, and is confined.—Armata, Part II.
