This life of Sterling will be useful to the class whose beliefs have given way before Mr. Carlyle's destroying energies; because it furnishes hints, not to be mistaken though not obtrusive, as to the extent to which they must be prepared to go if they would really be his disciples. If the path has in its very dangers an attraction for some, while others are shudderingly repelled, in either case the result is desirable, as it is the absence of certainty which causes the pain and paralyzes the power of action. At any rate, the doctrines of this teacher must be so much more intelligible to the mass when applied, as they are here, in commentary upon a life all whose details are familiar, because it is the life of a contemporary and a countryman, that all who read must inevitably be impressed with that great lesson of the philosophic poet-- "The intellectual power through words and things Goes sounding on, _a dim and perilous way_." Though John Sterling is of course the principal figure in the composition, and Mr. Carlyle's treatment the great attraction of the book, yet the figures in the background will be those to make most impression on the general reader. Coleridge stands there in striking but caricatured likeness; and even his most devoted admirers will not be sorry to see a portrait of their master by such a hand: and all will curiously observe the contrast between the sarcastic bitterness which colors the drawing of the philosophic Christian, and the kindly allowance through which the character of John Sterling's father, the famous "Thunderer" of the _Times_, is delineated.

There are besides, as in all Mr. Carlyle's works, passages of wise thought expressed in most felicitous language: of which not the least important is this advice given to Sterling in reference to his poetic aspirations:
