““Acknowledge the strengths of your opponent’s argument. If you are trying to persuade someone, why on earth would you want to lend credence to his argument? One reason is that the opposing argument almost certainly has value—something you can learn from and use to strengthen your own argument. This may seem hard to believe since you are so invested in your argument, but remember: we are blind to our blindness. Furthermore, an opponent who feels his argument is ignored isn’t likely to engage with you at all. He may shout at you and you may shout back at him, but it is hard to persuade someone with whom you can’t even hold a conversation.””
