Hogarth was quite surprised when "this figure stalked forwards to where he and Mr. Richardson were sitting and all at once took up the argument ... [with] such a power of eloquence, that Hogarth looked at him with astonishment, and actually imagined that this ideot had been at the moment inspired". Beyond appearance, Adam Smith claimed that "Johnson knew more books than any man alive", while Edmund Burke thought that if Johnson were to join Parliament, he "certainly would have been the greatest speaker that ever was there". Johnson relied on a unique form of rhetoric, and he is well known for his "refutation" of Bishop Berkeley's immaterialism, his claim that matter did not actually exist but only seemed to exist: during a conversation with Boswell, Johnson powerfully stomped a nearby stone and proclaimed of Berkeley's theory, "I refute it "thus"!" Johnson was a devout, conservative Anglican and a compassionate man who supported a number of poor friends under his own roof, even when unable to fully provide for himself. Johnson's Christian morality permeated his works, and he would write on moral topics with such authority and in such a trusting manner that, Walter Jackson Bate claims, "no other moralist in history excels or even begins to rival him". However, Johnson's moral writings do not contain, as Donald Greene points out, "a predetermined and authorized pattern of 'good behavior, even though Johnson does emphasise certain kinds of conduct. He did not let his own faith prejudice him against others, and had respect for those of other denominations who demonstrated a commitment to Christ's teachings. Although Johnson respected John Milton's poetry, he could not tolerate Milton's Puritan and Republican beliefs, feeling that they were contrary to England and Christianity. He was an opponent of slavery on moral grounds, and once proposed a toast to the "next rebellion of the negroes in the West Indies". Beside his beliefs concerning humanity, Johnson is also known for his love of cats, especially his own two cats, Hodge and Lily. Boswell wrote, "I never shall forget the indulgence with which he treated Hodge, his cat. Johnson was also known as a staunch Tory; he admitted to sympathies for the Jacobite cause during his younger years but, by the reign of George III, he came to accept the Hanoverian Succession. It was Boswell who gave people the impression that Johnson was an "arch-conservative", and it was Boswell, more than anyone else, who determined how Johnson would be seen by people years later.
