This is the complete 7 volume set of of the life of "Frederick the Great."
William Cowper Brann, "The Inconclast," writes about Carlyle that "Carlyle, greatest of critics, the supreme lord of literature --- that Scottish Arcturus before who even Shakespeare's glorius star pals its intellectual fires --- …" (Volume X, pp. 261 - 262)
McCabe writes about Carlyle that he "glorified Voltaire (in an essay on him) for 'giving the death-stab to modern superstion, and his Frederick the Great always eulogizes that monarch as a pupil of Voltaire. … Carlyle was one of the geatest Rationalist forces of his time, and one of the finest moral influences in Rationalism." Biographical Dictionary of Modern Rationalists, p. 141.
Conway, in writing about Carlyle's contribution to literature, writes "But even more widely
was Carlyle himself distributed. In what part of the earth have not his lines gone out and his labors extended? On how many hearts and minds, on how many lives, has he engraved passages which are transcripts of his own life, without which it can never be fully told? To report this one life, precious contributions must be brought from the lives of Goethe, Emerson, Jeffrey, Brewster, Sterling, Leigh Hunt, Mill, Mazzini, Margaret Fuller, Harriet
Martineau, Faraday. But how go on with the long catalogue? At its end, could that be reached, there would remain the equally important memories of lives less known, from which in the future may come incidents casting fresh light upon this central figure of two generations; and, were all told, time alone can bring the perspective through which his
genius and character can be estimated. In one sense, Carlyle was as a city set upon a bill, that cannot be hid; in another, he was an "open secret," hid by the very simplicity of his unconscious disguises, the frank perversities whose meaning could be known only by those close enough to hear the heart-beat beneath them; and many who have fancied that they had him rightly labelled with some moody utterance, or safely pigeon-holed in some outbreak of a soul acquainted with grief, will be found to have measured the oak by its mistletoe."
