• Poetry has this much, at least, in common with religion, that its standards were fixed long ago, by certain inspired writers, whose authority it is no longer lawful to call in question; and that many profess to be entirely devoted to it, who have no good works to produce in support of their pretensions. The catholic poetical church, too, has worked but few miracles since the first ages of its establishment; and has been more prolific, for a long time, of doctors than of saints: It has had its corruptions, and reformation also, and has given birth to an infinite variety of heresies and errors, the followers of which have hated and persecuted each other as cordially as other bigots.

• Since the beginning of our critical career, we have seen a vast deal of beautiful poetry pass into oblivion, in spite of our feeble efforts to recall or retain it in remembrance...The rich melodies of Keats and Shelley,—and the fantastical emphasis of Wordsworth,—and the plebeian pathos of Crabbe, are melting fast from the fields of our vision. The novels of Scott have put out his poetry. Even the splendid strains of Moore are fading into distance and dimness, except where they have been married to immortal music; and the blazing star of Byron himself is receding from its place of pride....The two who have the longest withstood this rapid withering of the laurel, and with the least marks of decay on their branches, are Rogers and Campbell.

• Damn the Solar System. Bad light; planets too distant; pestered with comets; feeble contrivance; could make a better one myself.
  • Sydney Smith, in a letter to Jeffrey, claimed this as his own parody of him: "If you could be alarmed into the semblance of modesty, you would charm everybody; but remember my joke against you about the Moon and the Solar System;— 'Damn the solar system! bad light—planets too distant—pestered with comets—feeble contriviance;—could make a better with great ease.'"
