Lord Byron Quote
Such writing is a sort of mental masturbation—he is always f—gg—g his imagination.—I don't mean that he is indecent but viciously soliciting his own ideas into a state which is neither poetry nor any thing else but a Bedlam vision produced by raw pork and opium.
letter to John Murray, 9 November 1820; in L. A. Marchand (ed.) Byron's Letters and Journals vol. 7 (1979)
