It’s hard enough to overcome one’s own misconceptions without having to think about how to get the resulting ideas past other people’s. I worry that if I wrote to persuade, I’d start to shy away unconsciously from ideas I knew would be hard to sell. When I notice something surprising, it’s usually very faint at first. There’s nothing more than a slight stirring of discomfort. I don’t want anything to get in the way of noticing it consciously.
