You will believe from these illustrations, Astrophel, that Seneca is right in his aphorism,—
“Nullum fit magnum ingenium sine misturâ dementiæ.”
And Pope also in his unconscious imitation,—
“Great wits to madness nearly are allied.”
Lord Castlereagh, when commanding in early life a militia regiment in Ireland, was stationed one night in a large desolate country house, and his bed was at one end of a long dilapidated room, while, at the other extremity, a great fire of wood and turf had been prepared within a huge gaping old-fashioned chimney. Waking in the middle of the night, he lay watching from his pillow the gradual darkening of the embers on the hearth, when suddenly they blazed up, and a naked child stepped from among them upon the floor. The figure advanced slowly towards Lord Castlereagh, rising in stature at every step, until, on coming within two or three paces of his bed, it had assumed the appearance of a ghastly giant, pale as death, with a bleeding wound on the brow, and eyes glaring with rage and despair. Lord Castlereagh leaped from his bed, and confronted the figure in an attitude of defiance. It retreated before him, diminishing as it withdrew in the same manner that it had previously shot up and expanded; he followed it, pace by pace, until the original child-like form disappeared among the embers. He then went back to his bed, and was disturbed no more.
The melancholy story of the Requiem of Mozart is an apt and sublime illustration of this influence. It was written by desire of a solemn personage, who repeatedly, he affirmed, called on him during its composition, and disappeared on its completion. The requiem was soon chanted over _his own_ grave; and the man in black was, I believe, but a phantom of his own creation.
A step beyond this, and we have the spectres of the delirium of fever: the wanderings of typhus, in which the victim either revels with delight in the regions of fancy, a midsummer madness, or is influenced by gloom and despair, in which, with a consciousness of right and wrong, he is driven headlong to acts of ruin and devastation.
IDA. In this illusive condition of the intellect consists even the monomania of suicide; and the phrenologist will declare that torpor or excitement of the “organ of the love of life,” will incite or deter from such an act. But surely this is error: it is certain that there was a _fashion_ among the Stoics for this crime; and even in the early history of Marseilles, suicide was sanctioned, not only by custom, but by authority.
