You could say that generally our culture goes in for large groups of people for two reasons. One is for entertainment and fun. The other is to get a useful job done. Now, I’m going to propose that in a dialogue we are not going to have any agenda, we are not going to try to accomplish any useful thing. As soon as we try to accomplish a useful purpose or goal, we will have an assumption behind it as to what is useful, and that assumption is going to limit us. Different people will think different things are useful. And that’s going to cause trouble.
