A periodical gets its weekly wad of books and sends off a dozen of them to X, the hack-reviewer, who has a wife and family and has got to earn his guinea, not to mention the half-crown per vol. which he gets by selling his review copies. There are two reasons why it is totally impossible for X to tell the truth about the books he gets. To begin with, the chances are that eleven out of the twelve books will fail to rouse in him the faintest spark of interest. They are not more than ordinarily bad, they are merely neutral, lifeless and pointless. If he were not paid to do so he would never read a line of any of them, and in nearly every case the only truthful review he could write would be: "This book inspires in me no thoughts whatever." But will anyone pay you to write that kind of thing? Obviously not. As a start, therefore, X is in the false position of having to manufacture, say, three hundred words about a book which means nothing to him whatever. Usually he does it by giving a brief resumé of the plot (incidentally betraying to the author the fact that he hasn't read the book) and handing out a few compliments which for all their fulsomeness are about as valuable as the smile of a prostitute.
