In schools, for example, there are courses in the criticism of literature, art criticism, and so forth. The arts are supposed to be 'not real.' It is quite safe, therefore, to criticize them in that regard -- to see how a story or a painting is constructed, or more importantly, to critically analyze the structure of ideas, themes, or beliefs that appear, say, in the poem or work of fiction. When children are taught science, there is no criticism allowed. They are told, 'This is how things are.' Science's reasons are given as the only true statements about reality, with which no student is expected to quarrel. Any strong intellectual explorations or counter versions of reality have appeared in science fiction, for example. Here scientists, many being science-fiction buffs, can channel their own intellectual questioning into a safe form. 'This is, after all, merely imaginative and not to be taken seriously.'
