Prabhupāda: No, you'll not compromise; at the same time, you'll not make enemies. That is tactics. If you make enemies, then what is your tactics? You must speak the truth; at the same time he'll not be displeased. That is tactics. If you can defeat him by your argument, then he'll not be displeased. After all, everyone is human being. If you can find out his defect, why he shall be enemy? Therefore, it is said, "You better make a reasonable man an enemy, but don't make a friend fool." You don't make friendship with a fool, but if a man is intelligent, better make him an enemy. Because, because he's intelligent, although he's an enemy, he'll not do any harm. Because intelligent. But a fool, he may pose himself as friend, and he can do anything which is very harmful.
Paramahaṁsa: So we should be able to see the quality of man we are preaching to.
Prabhupāda: Yes, you have to make him intelligent. Everyone is fool, mūḍha. Everyone within this material world is supposed to be a fool. Because everyone is thinking, "I am this body." So he's fool. "I am Indian," "I am American," "I am German," "I am Frenchman," "I am this," "I am that." What is the difference? A cat is thinking, "I'm cat." A dog is thinking, "I am dog." So if somebody thinks that, in relationship with the body, "I am Frenchman," "I am Englishman," "I am...", then where is the difference between the cat and the dog? He's thinking himself as this body. Therefore everyone is thinking, at least in this modern world, the so-called nationalism, everyone is thinking, "I am Englishman," "I am Frenchman," "I am Indian," "I am this," "black," "white." So everyone is fool.
