"The didactic writer is anything but moral because he is always simplifying the argument, always narrowing away, getting rid of legitimate objections. Mein Kampf is a moralistic book—a stupid, ugly one. A truly moral book is one that is radically open to persuasion, but looks hard at a problem, and keeps looking for answers. It gives you an absolutely clear vision, as if the poet, the writer, had nothing to do with it, had just done everything in his power to imagine how things are."

John Gardner, from a combination of interviews.
