But you think you correctly apply your basic ideas to specific situations. Tell me — where do you get this confidence? Because you think you do it right? But someone else disagrees with you. They think they're applying their ideas correctly too. Don't they think so? They do. Can both of you be right when you have opposite opinions? No, you can't. Can you show me anything better for applying these basic ideas than just thinking you're doing it right? A crazy person does what seems right to them too. Is 'it seems right to me' a good enough test for them? No, it's not. So we need something better than just what seems right. What is that?
But now since you think that you properly adapt the preconceptions to the particulars, tell me whence you derive this (assume that you do so). Because I think so. But it does not seem so to another, and he thinks that he also makes a proper adaptation; or does he not think so? He does think so. Is it possible then that both of you can properly apply the preconceptions to things about which you have contrary opinions? It is not possible. Can you then show us anything better towards adapting the preconceptions beyond your thinking that you do? Does the madman do any other things than the things which seem to him right? Is then this criterion sufficient for him also? It is not sufficient. Come then to something which is superior to seeming ([Greek: tou dochein]). What is this?
