Javier Marías at Threepenny Review:
I can think of seven reasons not to write novels:
First: There are too many novels and too many people writing them. Not only do those already written continue to exist and demand to be eternally read, but thousands more entirely new novels keep appearing in publishers’ catalogs and in bookshops around the world; then there are the many thousands rejected by publishers that never reach the bookshops, but which nonetheless exist. It is, then, a commonplace activity, one that is, in theory, within the grasp of anyone who learned to write at school, and for which no higher education or special training is required.
Second: And precisely because anyone, whatever his or her profession, can write a novel, it is an activity that lacks merit and mystery. Poets, philosophers, and dramatists do it; so do sociologists, linguists, publishers, and journalists; politicians, singers, TV presenters, and football coaches; engineers, school teachers, civil servants, and movie actors; critics, aristocrats, priests, and housewives; psychiatrists, university professors, soldiers, and goatherds.
