Amogha: Oh, yeah. In Bhagavad-gītā we claim that it is a fact scientifically that Kṛṣṇa appeared on earth and so many things. But actually isn't it because we believe that the Bhagavad-gītā is true that we think it is scientific? Because we believe it. But someone else would say, "I don't believe it, so for me it's not scientific."
Prabhupāda: Why it is not scientific? If Bhagavad-gītā says, annād bhavanti bhūtāni [Bg. 3.14], by eating sufficient grains, the living entity become flourished. So, can you deny it?
Amogha: That must be true.
Prabhupāda: Everything is true. If you think it properly, you'll find it is all true. Bhagavad-gītā says, cātur-varṇyaṁ mayā sṛṣṭaṁ: [Bg. 4.13] "By Me, the four divisions of human soceity are made." The most intelligent class, the brāhmaṇa, who knows the soul, God, etc., by their character, by their behavior. That is brāhmaṇa class. This is the most perfect way of keeping society. Unless there is a class which is very intelligent who know what is God, what is soul, then what is the civilization? Simply motorcar drivers? Is that civilization? Where is the brāhmaṇa? This is not civilization. Simply some artisans and workers, motorcar drivers, mill workers, where is civilized man, who knows God, who knows soul, who knows how to conduct the human society to the perfection? Where is that man? It is not civilization.
Paramahaṁsa: But we have philosophers and poets.
Prabhupāda: They are all loafer class. They have no information of the soul. They are studying in the dead matter, that's all. Freud and others, Darwin. What do they know?
