There is a vast difference between a text and a review. A text is a systematic dissertation of a given discipline; usually it covers the subject or the aspect of a subject with which it deals with varying depth and comprehensiveness. One can learn, or become more or less adept in a subject, by assiduous attention to texts. But a review book is something else; this parallel is made, for in our instant-knowledge era, students frequently attempt to learn just enough of some subjects to pass an examination. Whether this is the cause of our fragmented epistemological philosophy or the result of it is not clear. But it is clear that attempting to learn a subject without adequate background knowledge is a delusion. Thus, to use a review book when a textbook is indicated is splendid soil on which ignorance can thrive.
