Prabhupāda: I am a human being. You accept that I have got soul. By what symptoms you accept that I have got soul? First of all you have to ascertain that. What is the symptom that we agree that I am human being, I have got . . . I am a soul? By what characteristic, analytical study, you accept that I have got soul and the dog has not got soul?
What are these different characteristics? First of all, we have to enumerate that thing. If we find in the characteristics, then we can say there is no soul. But if we see that both the animal and the human being have the same characteristics of living condition, then how you can say the animal has not soul?
Yogeśvara: His point was that the animals don't show the same symptoms. They don't think as . . .
Prabhupāda: Why not? Why not? The general symptom is: animal eats, you eat; animal sleeps, you sleep; animal has sex, you have got sex; animal also defends, you also defend. Where is the difference?
