We spoke of the contrast which was manifest between the private and public life of Molière. These paradoxes are strange, but by no means uncommon in the character of men of genius. It will be remembered that Grimaldi, the cleverest and most mirth-provoking clown of his day in England, was often under medical treatment on account of his serious attacks of melancholy. It seems almost incredible that men of such profound judgment in most matters, as were Dr. Johnson and Addison, should have been so inexcusably weak as to entertain a belief in ghosts,--an eccentricity which neither of them denied. Byron,[202] who as a rule was noted for his shrewd common-sense, was so superstitious that he would not help a person at table to salt, nor permit himself to be served with it by another's hand. There were other equally absurd "omens" which he strenuously regarded. Cowper, who was a devoutly religious man, deliberately attempted to hang himself,--an act entirely at variance with his serious convictions. So also Hugh Miller, one of the most wholesome writers upon the true principles of life, wrested his own life from his Maker's hands. Pope, who was such a bravado with his pen, boldly denouncing an army of scholars and wits in his "Dunciad," was personally an arrant coward, who could not summon sufficient self-possession to make a statement before a dozen of his personal friends. The paradox which existed between Goldsmith's pen and tongue passed into an axiom: with the one he was all eloquence and grace; with the other, as foolish as a parrot. Douglas Jerrold, whose forte was as clearly that of wit and humor as it is the sun's province to shine, was ever wishing to write a profound essay on natural philosophy. Newton, highest authority in algebra, could not make the proper change for a guinea without assistance, and while he was master of the Mint was hourly put to shame by the superior practical arithmetic of the humblest clerks under him. Another peculiarity of Newton was that he fancied himself a poet; but who ever saw a verse of his composition? Judged by all accepted rules, Charles Lamb experienced ills sufficient to have driven him to commit suicide; whereas the truth shows that with "his sly, shy, elusive, ethereal humor" he was ordinarily the most genial and contented of beings.
