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."
Śyāmasundara: He's not so much talking about what is the duty, but that these two things are what motivate our moral behavior. They are what check and safeguard our moral behavior: one is conscience, or my own sense of duty, whatever that may be.
Prabhupāda: But how you will know it is? He says that one should know whatever his duty. So whatever what is his duty, how he will know it?
Śyāmasundara: Well, that, our duty is that which produces the most good for the most people.
Prabhupāda: This is also vague. This is also vague. There is no definite understanding.
Śyāmasundara: Just like the golden rule, "Do unto others."

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?
Śyāmasundara: John Stuart Mill.
Prabhupāda: 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.
Śyāmasundara: He would agree with that also, but here he says that the higher authorities who determine what is duty, that their rationale or their guiding principles should be what is the greatest good for the greatest number, and that should be our duty.
Prabhupāda: Then how he suggests that a man should know his duty, like that? Then he has to approach that greatest authority. Tad vijñānārthaṁ sa gurum evābhigacchet (MU 1.2.12). That is our philosophy. In order to know our duty, in order to know what is knowledge, we must approach a guru. Gurum evābhigacchet. We must, eva, certainly.
Śyāmasundara: His guiding principle for that, to determine what is the greatest good for the greatest number, is the golden rule of the Christians, "Do unto others as you..."
Prabhupāda: That means you have to approach Christ through... One cannot determine himself. Golden rules of Christianity means that he has to abide by the orders of Christ. That is superior authority.
