Answer: Conscience is the cream of the mind. The best that the mind has produced is conscience. It is a product of the mind, and therefore the conscience of a person living in one nation is quite different from the conscience of a person in another nation: it is built in another element. For instance, in ancient times there were communities of robbers. Now there are nations. The robbers used to think that they were entitled to rob the caravans passing by; they had a moral principle and an ideal. If a person said, "All I have I give you, let me go" they said, "No, I wish to see blood from your hand." They did not let him go without hurting him. What was their principle? They thought, "We do not accept anything from you, we are not beggars, we are robbers. We risk our lives for our profession, we defend ourselves risking our lives, we are brave, we are entitled to it, we are courageous." It was the same with the sea pirates; they thought what they did was virtue, and from that thought they became kings. The same people when small were robbers, when great became kings.
