It’s not fear of people disagreeing with me. It’s not that I wish to avoid criticism; it’s that I think that the act of arguing is almost always a poor use of time. (…) I figure that if people feel strongly enough about what I’ve written that they feel compelled to contact me then my email address is plastered all over this website. In this way the feedback that does reach me tends to be the kind that I am more likely to be interested in.
