Input: Read this: In the nineteenth century Burke was praised by both liberals and conservatives. Burke's friend Philip Francis wrote that Burke "was a man who truly & prophetically foresaw all the consequences which would rise from the adoption of the French principles" but because Burke wrote with so much passion, people were doubtful of his arguments. William Windham spoke from the same bench in the House of Commons as Burke had, when he had separated from Fox, and an observer said Windham spoke "like the ghost of Burke" when he made a speech against peace with France in 1801. William Hazlitt, a political opponent of Burke, regarded him as amongst his three favourite writers (the others being Junius and Rousseau), and made it "a test of the sense and candour of any one belonging to the opposite party, whether he allowed Burke to be a great man". William Wordsworth was originally a supporter of the French Revolution and attacked Burke in 'A Letter to the Bishop of Llandaff' (1793), but by the early nineteenth century he had changed his mind and came to admire Burke. In his Two Addresses to the Freeholders of Westmorland Wordsworth called Burke "the most sagacious Politician of his age" whose predictions "time has verified". He later revised his poem The Prelude to include praise of Burke ("Genius of Burke! forgive the pen seduced/By specious wonders") and portrayed him as an old oak. Samuel Taylor Coleridge came to have a similar conversion: he had criticised Burke in The Watchman, but in his Friend (1809–10) Coleridge defended Burke from charges of inconsistency. Later, in his Biographia Literaria (1817) Coleridge hails Burke as a prophet and praises Burke for referring "habitually to principles. He was a scientific statesman; and therefore a seer". Henry Brougham wrote of Burke: "... all his predictions, save one momentary expression, had been more than fulfilled: anarchy and bloodshed had borne sway in France; conquest and convulsion had desolated Europe...the providence of mortals is not often able to penetrate so far as this into futurity". George Canning believed that Burke's Reflections "has been justified by the course of subsequent events; and almost every prophecy has been strictly fulfilled". In 1823 Canning wrote that he took Burke's "last works and words [as] the manual of my politics". The Conservative Prime Minister Benjamin Disraeli "was deeply penetrated with the spirit and sentiment of Burke's later writings".
