You see we make our writers into something very strange. […] We destroy them in many ways. First, economically. They make money. It is only by hazard that a writer makes money although good books always make money eventually. Then our writers when they have made some money increase their style of living and are caught. They have to write to keep up their establishment, their wives, and so on, and they write slop. It is slop not on purpose but because it is hurried. Because they are ambitious. Then, once they have betrayed themselves, they justify it and you get more slop. Or else they read the critics. If they believe the critics when they say they are great then they must believe them when they say they are rotten and they lose confidence. At present we have two good writers who cannot write because they have lost confidence through reading the critics. If they wrote, sometimes it would be good and sometimes not so good and sometimes it would be quite bad, but the good would get out. But they have read the critics, and they must write masterpieces. The masterpieces the critics said they wrote. They weren’t masterpieces, of course. They were just quite good books. So now they cannot write at all. The critics have made them impotent.
