Prabhupāda: The science does... They conclude something, and next man changes. So that is your science. So how you can make a conclusion?
Svarūpa Dāmodara: But how so many things are working under the laws...?
Prabhupāda: Working, that's all right. You have seen that so many people are dying. That's all right. But I am challenging that you have not seen the next man who does not die. That you cannot answer.
Svarūpa Dāmodara: For example, they find the laws of motion, Newton's laws of motion. They utilize that concept in shooting rockets. And they use exactly some mathematical formula and apply it.
Prabhupāda: That's all right, but sometimes the shooting of the rocket missing.
Svarūpa Dāmodara: No, what we are saying is that the law that they find out by their own effort is working...
Prabhupāda: So you effort is limited. How you can conclude?
Svarūpa Dāmodara: So inductive knowledge is true to a certain limit.
Prabhupāda: Certain extent, that's all. It is not conclusion.
Svarūpa Dāmodara: But to a devotee, though, there is nothing like inductive knowledge because knowledge gives by Kṛṣṇa. So it must be deductive.
Prabhupāda: Deductive always. And that is easier. Kṛṣṇa says that "I come as death and take away everything." So we know that nobody can be immortal; everyone must die. Simple conclusion.
Brahmānanda: We don't have to test it because Kṛṣṇa says it.
Prabhupāda: Yes. You take that...
Ravīndra-svarūpa: We could never know ourselves unless we knew all cases.
Prabhupāda: No, we do not require to know. We hear from Kṛṣṇa, the Supreme Person. That is perfect
Devotee: That's our logic. You said that once.
Prabhupāda: Yes, that is our logic.
Gurudāsa: But also you said once that we feel it. That is our proof.
Prabhupāda: No, feel, you may wrongly feel because you are imperfect. That is not good argument. Our argument is that the message is coming from the most authorized personality; therefore it is perfect. And we receive guru-paramparā. That is our process. Evam paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). The rājarṣis, means very, very, big, big, stalwart persons, they accept it. Just like Arjuna gives evidence that "I accept You. You are Parabrahma." So he, next line, he says, "It is not that I am saying. But big, big personalities like Vyāsadeva, he has said. Nārada has said. Asita has said. And You are personally saying, so I have no doubt." This is our process. (break) ...Upendra, Upendra has not come? (break) ...knowledge is always imperfect.
