“A great man shows his greatness by the way he treats little men.”
Attributed to Carlyle in Dale Carnegie's How to Win Friends And Influence People (1936), but this quotation is not found in Carlyle's known works. The first mention found in Google Books dates from 1908, where the Rev. John Timothy Stone https://en.wikipedia.org/wiki/John_Timothy_Stone is quoted as claiming: 'The greatest critics of this world have been appreciators. Carlyle said, "You can discover a great man, or see a great man, by the way he treats little men.'
The quotation is subsequently found in slightly different forms, mostly in religious publications: "A great man shows his greatness by manner in which he treats little men" (1913, unattributed); The exact wording of Carnegie's quote suggests that it was taken from Stone's 1930 publication.

“The greatness of a nation and its moral progress can be judged by the way its animals are treated.”
Widely attributed to Gandhi, sometimes citing Ramachandra Krishna Prabhu, The Moral Basis of Vegetarianism (1959). (Cf. Ralph Keyes, The Quote Verifier (2006), p. 74.) However, it is not found in that essay http://www.mkgandhi.org/ebks/moralbasis_vegetarianism.pdf nor in any of Gandhi's Complete works. http://animalsmattertogod.com/2013/09/13/mahatma-gandhi-hoax-quote-greatness-of-a-nation-and-its-moral-progress-can-be-judged-by-the-way-that-its-animals-are-treated/
The original quote seems to be by David Strauss, The Old Faith and the New (Der alte und der neue Glaube, 1872, trans. by M. Blind, New York: Henry Holt & Co., 1873), vol. II, ch. 71, p. 59 https://archive.org/stream/oldfaithnewconfe01stra#page/59/mode/2up: The manner in which a nation in the aggregate treats animals, is one chief measure of its real civilization.
Similar quotes, not attributed to Gandhi, are found throughout the twentieth century: e.g. The great actress, Mrs Fiske, once said to me, "The civilization of any country can be told by the way it treats its animals" (Zoe Berkeley, "Zoe Berkeley's Corner", Salinas Index-Journal, 1933-07-01, p. 8).
Attributed to Gandhi since at least 1980: The seal hunt truly is Canada's shame and we would do well to think of the words of Gandhi when he said, "The greatness of a nation and its moral progress can be judged by the way its animals are treated" (Doris Potter, Letter to the editor, The Gazette (Montreal), 1980-03-18, p. 8).
