Autobiography (1873)
Context: In these frequent talks about the books I read, he used, as opportunity offered, to give me explanations and ideas respecting civilization, government, morality, mental cultivation, which he required me afterwards to restate to him in my own words. He also made me read, and give him a verbal account of, many books which would not have interested me sufficiently to induce me to read them of myself: among others, Millar's Historical View of the English Government, a book of great merit for its time, and which he highly valued; Mosheim's Ecclesiastical History, McCrie's Life of John Knox, and even Sewel's and Rutty's Histories of the Quakers. He was fond of putting into my hands books which exhibited men of energy and resource in unusual circumstances, struggling against difficulties and overcoming them: of such works I remember Beaver's African Memoranda, and Collins's account of the first settlement of New South Wales.

“Tis very strange Men should be so fond of being thought wickeder than they are.”
