A maxim which it would be well for ambitious critics to chalk up on the walls of their workshops is this: never mind whom you praise, but be very careful whom you blame. Most critical reputations have struck on the reef of some poet or novelist whom the great censor, in his proud old age, has thought he might disdain with impunity. Who recollects the admirable treatises of John Dennis, acute, learned, sympathetic? To us he is merely the sore old bear, who was too stupid to perceive the genius of Pope. The grace and discrimination lavished by Francis Jeffrey over a thousand pages, weigh like a feather beside one sentence about Wordsworth's _Excursion_, and one tasteless sneer at Charles Lamb. Even the mighty figure of Sainte-Beuve totters at the whisper of the name Balzac. Even Matthew Arnold would have been wiser to have taken counsel with himself before he laughed at Shelley. And the very unimportant but sincere and interesting writer, whose book occupies us to-day, is in some respects the crowning instance of the rule. His literary existence has been sacrificed by a single outburst of petulant criticism, which was not even literary, but purely political. The only passage of Winstanley's _Lives of the English Poets_ which is ever quoted is the paragraph which refers to Milton, who, when it appeared, had been dead thirteen years. It runs thus: "_John Milton_ was one whose natural parts might deservedly give him a place amongst the principal of our English Poets, having written two Heroick Poems and a Tragedy, namely _Paradice Lost, Paradice Regain'd_, and _Sampson Agonista_. But his Fame is gone out like a Candle in a Snuff, and his Memory will always stink, which might have ever lived in honourable Repute, had not he been a notorious Traytor, and most impiously and villanously bely'd that blessed Martyr, King _Charles_ the First."
