Besides, humor does not wear well. It is commonly enough said, that a joke will not bear repeating. The deepest humor will not keep. Humors do not circulate but stagnate, or circulate partially. In the oldest literature, in the Hebrew, the Hindoo, the Persian, the Chinese, it is rarely humor, even the most divine, which still survives, but the most sober and private, painful or joyous thoughts, maxims of duty, to which the life of all men may be referred. After time has sifted the literature of a people, there is left only their SCRIPTURE, for that is WRITING, _par excellence_. This is as true of the poets, as of the philosophers and moralists by profession; for what subsides in any of these is the moral only, to reappear as dry land at some remote epoch. We confess that Carlyle’s humor is rich, deep, and variegated, in direct communication with the backbone and risible muscles of the globe,—and there is nothing like it; but much as we relish this jovial, this rapid and delugeous way of conveying one’s views and impressions, when we would not converse but meditate, we pray for a man’s diamond edition of his thought, without the colored illuminations in the margin,—the fishes and dragons, and unicorns, the red or the blue ink, but its initial letter in distinct skeleton type, and the whole so clipped and condensed down to the very essence of it, that time will have little to do. We know not but we shall immigrate soon, and would fain take with us all the treasures of the East; and all kinds of _dry_, portable soups, in small tin canisters, which contain whole herds of English beeves boiled down, will be acceptable. The difference between this flashing, fitful writing and pure philosophy is the difference between flame and light. The flame, indeed, yields light; but when we are so near as to observe the flame, we are apt to be incommoded by the heat and smoke. But the sun, that old Platonist, is set so far off in the heavens, that only a genial summer-heat and ineffable daylight can reach us. But many a time, we confess, in wintry weather, we have been glad to forsake the sunlight, and warm us by these Promethean flames. Carlyle must undoubtedly plead guilty to the charge of mannerism. He not only has his vein, but his peculiar manner of working it. He has a style which can be imitated, and sometimes is an imitator of himself.
