David Masson, Edinburgh sketches & memories (1892)
“ It is impossible to suppose that Carlyle, at this period of his life or at any other, can have been all unhappy, even when he thought himself most unhappy. There must have been ardours and glows of soul, great joys and exhilarations, corresponding to the complexity of nervous endowment that could descend to such depths of sadness. From himself we learn, in particular, how the society of Irving, whether in their Annandale meetings, or in Irving’s visits to Edinburgh, had always an effect upon his spirits like that of sunrising upon night or fog. ”
