Scott, whose generous soul was hurt by the harsh squabbles of the Scottish reviewers, took a shot at the tribe in the letter which appears in the introductory note to "The Lay of the Last Minstrel" in the Cambridge edition:
As to the herd of critics, it is impossible for me to pay much attention to them for, as they do not understand what I call poetry, we talk in a foreign language to each other. Indeed, many of these gentlemen appear to me to be a sort of tinkers, who, unable to make pots and pans, set up for menders of them, and, God knows, often make two holes in patching one.
The idea that the critic is a secondary fellow who cannot make first-hand literature goes back to Dryden, the champion and exemplar of sound criticism, who wrote in "The Conquest of Granada":
They who write ill and they who ne'er durst write
Turn critics out of mere revenge and spite.
Landor repeats the idea in a "Conversation" between Southey and Porson, in which Porson says: "Those who have failed as writers turn reviewers."
Writers and other artists are usually sensitive and often vain. Some have taken critics too seriously, have given them too much importance while pretending to despise them, and have allowed themselves to be stung instead of brushing the flies off. Thanks to Shelley, the idea became current that the "viperous murderer," the critic, killed Keats. It was not so. Keats died of tuberculosis. Though he was, like all poets, delicately organized, he was an unusually sane and self-reliant man, quite sure of the value of his work. Moreover, in a day when rough criticism was the fashion, the critics were, though stupid, not especially rough on Keats. Shelley's "J'accuse" is flaming poetry, but—it is not good criticism. Byron had the right idea. With his superior wit and vigour he gave the reviewers ten blows for one and used his opponents as the occasion of a delightful exhibition of boxing. The reviewers were knocked out in the second round. "English Bards and Scottish Reviewers" is still in the ring, as I have pleasantly discovered by re-reading it.
The notion that the critic will, or can, do damage to the artist persisted long after Shelley and is perhaps still believed. In 1876, Sidney Lanier, a man of good sense and great bravery, whom the flies, or the "vipers," had but lightly nipped, wrote in a letter to his father:
What possible claim can contemporary criticism set up to respect—that criticism which crucified Jesus, stoned Stephen, hooted Paul for a madman, tried Luther for a criminal, tortured Galileo, bound Columbus in chains, drove Dante into a hell of exile, made Shakespeare write the sonnet, "When in disgrace of fortune and men's eyes," gave Milton £5 for "Paradise Lost," kept Samuel Johnson cooling his heels on Lord Chesterfield's doorstep, reviled Shelley as an unclean dog, killed Keats, cracked jokes on Gluck, Schubert, Beethoven, Berlioz, and Wagner, and committed so many other impious follies and stupidities?
Lanier's charges are not all quite true. He mixed up the sins of criticism with the sins of politics, economics, and other dreadful affairs. But his outburst is a good illustration of the quarrel between the "author" and the "critic." Especially when the author has for the moment lost his sense of humour.
