One of the most vital and pregnant books in our modern literature, Sartor Resartus is also, in structure and form, one of the most daringly original. It defies exact classification. It is not a philosophic treatise. It is not an autobiography. It is not a romance. Yet in a sense it is all these combined. Its underlying purpose is to expound in broad outline certain ideas which lay at the root of Carlyle’s whole reading of life.
