Srimad-Bhagavatam
SB Canto 4
Lectures
Philosophy Discussions
Syamasundara: Well, that, our duty is that which produces the most good for the most people.
Prabhupada: This is also vague. This is also vague. There is no definite understanding.
Syamasundara: Just like the golden rule, "Do unto others."
Prabhupada: Then if I conclude that most of the people are taking LSD, so to take LSD is my duty. Is that all right? He is vague. This is not philosophy. How a rascal can conclude about his duty? Rascal has to be trained to know what is duty. A rascal cannot conclude out of his own accord that "This is my duty" or "This is the best thing." Mr. Stuart... What is his name?
Syamasundara: John Stuart Mill.
Prabhupada: John Stuart, he may be able, but it is not possible for ordinary man to know what is duty. The child plays, he does not know that his duty is to study. So parents teach him that "This is your duty. You must go to school. You must learn." So duty is not created by the rascals and fools. Duty is created by higher authority.
