Svarūpa Dāmodara: So we'll explain there are two types of acquiring knowledge. Two different techniques. Now the scientists are believing their own . . .
Prabhupāda: That is imperfect. Inductive knowledge is always imperfect. Deductive knowledge is perfect if it is taken from the authority. Suppose man is mortal. So inductive process is that you examine every man, whether he's mortal or immortal. So suppose you have seen millions of men, and they are all mortal, they die. Then your conclusion is man is mortal. But I can say you have not seen a man who does not die. I can say that. So this inductive knowledge will remain always imperfect. It will never be perfect, because your examination is limited. So I can that say you have not seen the person, man . . . suppose if I say: "You have not seen Vyāsadeva, he's immortal. You have not seen Aśvatthāmā, he's immortal." So how this scientific research can be perfect, inductive? It is never perfect. Because you may be missing somebody who is immortal, then your conclusion is wrong. There is no scope of studying all the living beings. There is no such scope. You have limited scope. So your seeing power is limited. How you can decide from the limited seeing power?
Rūpānuga: They will say: "Well, we have done so many good things, we have produced so many nice things."
Prabhupāda: You have done nothing good, I say. You have simply wasted time and taken public money, that's all.
Rūpānuga: "We have made some mistakes, but we have produced some good things in medicine and, anyway, you should accept our authority because we have done so many good things."
Prabhupāda: No, because you have done something, that I accept. Just like you have done very good, 747 aeroplane, but just make a mosquito, with pilot and everything. Can you do it? Then why do you take all the credit. Take credit for 747, that's all. But when I ask you, "Create another plane like a fly or mosquito," you are unable to do it. Then why do you take, "There is no God, science is everything." Why do you say like that?
Svarūpa Dāmodara: That's why we want to bring up this point that, "Scientists, we are not claiming that you are all nonsense, but you are all good men, but you should know your limits."
Prabhupāda: You should not be so proud falsely—that is our point—and mislead others that there is no God. Because you are accepted as authority, scientist, if you say that there is no God, they will accept it. Then our back to Godhead movement is stopped. Then we must stop your also nonsense. It is a fight. Because you say there is no God, and we say you are all nonsense. We must say it. You are challenging; we must challenge. But you accept God, then we have nothing . . . I think Sir Isaac Newton said like that, "The vast knowledge, we have simply gathered a few grains of sand on the beach of knowledge," something like that. That is good.
Svarūpa Dāmodara: Yes, humble.
Prabhupāda: That is good. But how you can say there is no God, everything is science? And misleading people. That must be stopped. You take credit as much as you have done. That we are ready to give you. Because you have created one aeroplane, 747, therefore you can do everything, if you do . . . like that, that is misleading. That we cannot . . .
Svarūpa Dāmodara: Yes, once that very concept that they will be able to do all these things, if that is removed, then they come on the platform as . . .
Prabhupāda: Sane man. They are talking like insane man.
