Prabhupāda: The small birds, tiny birds, they are solving their economic question, coming (makes sound:) "bup, bup," finished. They are not stocking, they are not thinking of tomorrow, but are satisfied. They have got eating, sufficient eating, sufficient sex, sufficient intelligence to defend. As soon as we go, immediately they fly away. That is defense. They know how to defend them. They immediately understand, "They are human beings, stronger. They may do some harm. Let us fly away." So these things are everywhere, eating, sleeping, mating and defending. There is no scarcity. Only scarcity is Kṛṣṇa consciousness. That we have to preach. Theology... Logy means science, is it not?
Svarūpa Dāmodara: Yes.
Prabhupāda: Everything, logy means science. So theology is also science. Why they reject theology "Yes, you are talking..." What kind of scientist you are? It is a "logy," it is a science. Why you are giving preference to one "logy" to another? What kind of scientist you are? Even though I am talking of theology, why should you reject it? In Vedic knowledge, "logy" is the basic... Nyāya-prasthāna, śruti-prasthāna, smṛti-prasthāna. These are the three ways of understanding the Absolute Truth.
Svarūpa Dāmodara: Logic and argument?
Prabhupāda: Yes. Nyāya-pra... Just like Vedānta-sūtra, it is logic and argument to approach the Absolute Truth. Athāto brahma jijñāsā: "Now it is the time for inquiring about Brahman." This is logic.
