Mostly Extracts
pp24–25“There is no stronger characteristic of human nature than its being open to the grossest contradictions: one of Lord Herbert's arguments against revealed religion is the improbability that Heaven should reveal its will to only a portion of the earth which he terms particular religion.”
Fuller, Margaret. "Mostly Extracts." Houghton Library, Harvard University; bMS Am 1086 (89); Box 5 (89).
Inferred Fuller names 'Lord Orford' without specifying a title. The quoted passage ('There is no stronger characteristic of human nature...') is from Walpole's preface to the 1764 edition of the Life of Lord Herbert, which he edited. Fuller heads this section 'Lord Orford says of his' (i.e., of Herbert's work).
