The conventional wisdom has it that there are writers’ writers and readers’ writers. The latter are those happy few whose books, by some pheromonic chemistry the former can never quite duplicate in their own laboratories, appear year after year on the best seller lists. They may or (more usually) may not satisfy the up-market tastes of “literary” critics but their books sell. Writers’ writers get great reviews, especially from their admiring colleagues, but their books don’t attract readers, who can recognize, even at the distance of a review, the signs of a book by a writers’ writer. The prose style comes in for high praise (a true readers’ writer, by contrast, would not want to be accused of anything so elitist as “style”); the characters have “depth”; above all, such a book is “serious.”

Many writers’ writers aspire to the wider fame and higher advances of readers’ writers, and occasionally a readers’ writer will covet such laurels as royalties cannot buy. Henry James, the writers’ writer par excellence wrote one of his drollest tales, The Next Time, about just such a pair of cross-purposed writers, and James’s conclusion is entirely true to life. The literary writer does his best to write a blockbuster—and it wins him more laurels but no more readers. The successful hack does her damnedest to produce a Work of Art: the critics sneer, but it is her greatest commercial success.

Philip K. Dick was, in his time, both a writers’ writer and a readers’ writer; and neither; and another kind altogether—a science fiction writers’ science fiction writer. The proof of the last contention is to be found blazoned on the covers of a multitude of his paperback books, where his colleagues have vied to lavish superlatives on him. John Brunner called him “the most consistently brilliant
