Member of the Scottish bar, but devoted in an intensely human spirit to theological interests, "one of the gentlest, kindliest, best bred of men," says Carlyle, who was greatly attached to him; "I like him," he says, "as one would do a draught of sweet rustic mead served in cut glasses and a silver tray ... talks greatly of symbols, seems not disinclined to let the Christian religion pass for a kind of mythus, provided one can retain the spirit of it"; he wrote a book, much prized at one time, on the "Internal Evidences of Revealed Religion," also on Faith; besides being the constant friend of Carlyle, he corresponded on intimate terms with such men as Maurice and Dean Stanley (1788-1870).
