Śyāmasundara: So I understand that, and I'll accept that, but the one thing I'm still puzzled on is that there's no geological evidence that in former times on this planet there were more complex forms...
Prabhupāda: Why you are taking geological evidence as final? Why you are taking that? That is final?
Śyāmasundara: But it's logical...
Prabhupāda: What logic? Science is progressing. You cannot say that this is final.
Karandhara: Scientists couldn't deny; they could just say that we haven't found any evidence.
Prabhupāda: Yes.
Śyāmasundara: But until there's something that disproves it to me, then I must accept it, because it..., because it's logical.
Karandhara: But that's a false platform. I'll conclude on the basis of my limited knowledge because I don't have the perfect knowledge. That's an abortion of the whole scientific...
Śyāmasundara: Yes. All right. You can say that I've never seen a purple man, so there must be no such thing as a purple man. You can say that, but as far as I can operate within my practicality, there are no purple men. I've never seen one; no one has ever seen purple men. So isn't this logical?
Prabhupāda: Purple men?
Śyāmasundara: I'm just using it as an example.
Prabhupāda: What is that purple men? But you have not also seen, why you are speaking like that?
Śyāmasundara: I'm using it as an example of an exception.
Prabhupāda: No, no. What, you are scientist, what you have never seen, why you are thinking of like that? That is my point.
Śyāmasundara: I'm using it as an example of an exception...
Prabhupāda: Why example? Why you give a fictitious example which you have no experience?
Śyāmasundara: All right. So let's say no one has ever seen a...
Prabhupāda: No, no. That is another thing. You cannot say which you have never seen, at least. Because yours is experimental, I may say, but you at least, cannot say like that.
