It is folly to say that this or that kind of humor is too good for the public, that only a chosen few can relish it. The best humor that we know of has been as eagerly received by the public as by the most delicate connoisseur. There is hardly a man in England who can read but will laugh at Falstaff and the humor of Joseph Andrews; and honest Mr. Pickwick's story can be felt and loved by any person above the age of six. Some may have a keener enjoyment of it than others, but all the world can be merry over it, and is always ready to welcome it. The best criterion of good humor is success, and what a share of this has Mr. Cruikshank had! how many millions of mortals has he made happy! We have heard very profound persons talk philosophically of the marvellous and mysterious manner in which he has suited himself to the time--fait vibrer la fibre populaire (as Napoleon boasted of himself), supplied a peculiar want felt at a peculiar period, the simple secret of which is, as we take it, that he, living amongst the public, has with them a general wide-hearted sympathy, that he laughs at what they laugh at, that he has a kindly spirit of enjoyment, with not a morsel of mysticism in his composition; that he pities and loves the poor, and jokes at the follies of the great, and that he addresses all in a perfectly sincere and manly way. To be greatly successful as a professional humorist, as in any other calling, a man must be quite honest, and show that his heart is in his work. A bad preacher will get admiration and a hearing with this point in his favor, where a man of three times his acquirements will only find indifference and coldness. Is any man more remarkable than our artist for telling the truth after his own manner? Hogarth's honesty of purpose was as conspicuous in an earlier time, and we fancy that Gilray would have been far more successful and more powerful but for that unhappy bribe, which turned the whole course of his humor into an unnatural channel. Cruikshank would not for any bribe say what he did not think, or lend his aid to sneer down anything meritorious, or to praise any thing or person that deserved censure. When he levelled his wit against the Regent, and did his very prettiest for the Princess, he most certainly believed, along with the great body of the people whom he represents, that the Princess was the most spotless, pure-mannered darling of a Princess that ever married a heartless debauchee of a Prince Royal. Did not millions believe with him, and noble and learned lords take their oaths to her Royal Highness's innocence? Cruikshank would not stand by and see a woman ill-used, and so struck in for her rescue, he and the people belaboring with all their might the party who were making the attack, and determining, from pure sympathy and indignation, that the woman must be innocent because her husband treated her so foully.
