“Rational argument can be conducted with some prospect of success only so long as the emotionality of a given situation does not exceed a critical degree.”

“Do you know, the only people I can have a conversation with are the Jews? At least when they quote scripture at you they are not merely repeating something some priest has babbled in their ear. They have the great merit of disagreeing with nearly everything I say. In fact, they disagree with almost everything they say themselves. And most importantly, they don’t think that shouting strengthens their argument.”

“If there is no disparity of opinions there is nothing of value being discussed”

“I think there’s a difference between (a) offending people for its own sake, which I don’t necessarily want to do, because some people are good and decent and it would be unkind to upset them simply to indulge my own self-importance, and (b) challenging their prejudices, their preconceptions, or their comfortable assumptions. I’m very happy to do that. But we need to be on our guard when people say they’re offended. No one actually has the right to go through life without being offended. Some people think they can say “such-and-such offends me” and that will stop the “offensive” words or behaviour and force the “offender” to apologise. I’m very much against that tactic. No one should be able to shut down discussion by making their feelings more important than the search for truth. If such people are offended, they should put up with it.”

“Discussion is impossible with someone who claims not to seek the truth, but already to possess it.”
