Prabhupāda: Yes. Darwin's nonsense is there. He is changing the apartment. Apartment is becoming a different apartment. That is not a fact. Just try to understand. This room cannot develop into another room. But I, the resident of this room, I can go from this apartment to another apartment. Or I can create another apartment. This is evolution.
Dr. Hauser: And I can create a bigger apartment.
Prabhupāda: Yes, bigger, smaller, as I like. Not necessarily bigger. That is also another nonsense.
Dr. Hauser: And my intelligence might grow also.
Prabhupāda: Intelligence, maybe. But there must be means. You may be very intelligent, but if you have no means to erect another nice apartment, how it will?
Dr. Hauser: Trial and error.
Prabhupāda: Eh?
Dr. Hauser: Trial and error.
Prabhupāda: Just like you have got the desire to purchase another dress, garment, nicer, but if you have no money, then how you can purchase? You have to purchase something inferior. So these different species of life is the evolution of the living soul according to his karma. That is Vedic instruction. Karmaṇā daiva-netreṇa (SB 3.31.1). So I am a living entity. If I want to go to better condition of life, then I'll have to pay for it. Better condition is there already. Not this inferior condition changes into that better condition. That is another thing.
