Now it is impossible to review a book as you would factor a number or a play. You can’t be sure of the factors that make up the collective impact of the book upon you. There’s no way of getting at them. They are summed up in the book itself and no book can be split into multipliable parts. A book is not the author times an idea times the views of the publisher. A book is unfactorable, often undecipherable. It is a growth. It is a series of accretions about a central thought. The central thought is like the grain of sand which the oyster has pearled over. The central thought may even be a diseased thought and the pearl may be a very lovely and brilliant pearl, superficially at least, for all that. There is nothing to do with a book but to take it as it is or go at it hammer and tongs, scalpel and curette, chisel and auger--smashing it to pieces, scraping and cutting, boring and cleaving through the layers of words and subsidiary ideas and getting down eventually to the heart of it, to the grain of sand, the irritant thought that was the earliest foundation. Such surgery may be highly skilful or highly and wickedly destructive; it may uncover something worth while and it may not; naturally, you don’t go in for much of it, if you are wise, and as a general thing you take a book as it is and not as it once was or as the author may, in the innocence of his heart or the subtlety of his experience, have intended it to be. 6 Surgery on a book is like surgery on a human being, for a book is alive; ordinarily the only justification for it is the chance of saving life. If the operator can save the author’s life (as an author) by cutting he ought to go ahead, of course. The fate of one book is nothing as against the lives of books yet unwritten; the feelings of the author are not necessarily of more account than the screams of the sick child’s parent. There have been such literary operations for which, in lieu of the $1,000 fee of medical practise, the surgeon has been rewarded and more than repaid by a private letter of acknowledgement and heartfelt thanks. No matter how hard up the recipient of such a letter may be, the missive seldom turns up in those auction rooms where the A. L. S. (or Autograph Letter with Signature) sometimes brings an unexpected and astonishingly large price. 7
