What You Can’t Say

Paul Graham: This essay is about heresy: how to think forbidden thoughts, and what to do with them. The latter was till recently something only a small elite had to think about. Now we all have to, because the Web has made us all publishers.

The trouble with keeping your thoughts secret, though, is that you lose the advantages of discussion. Talking about an idea leads to more ideas. So the optimal plan, if you can manage it, is to have a few trusted friends you can speak openly to. This is not just a way to develop ideas; it’s also a good rule of thumb for choosing friends. The people you can say heretical things to without getting jumped on are also the most interesting to know.
