Is there any common standard of duty?

Question: Is there any common standard of duty?

Answer: There cannot be any universal ‘Objective Standard’; but there is a ‘Subjective Principle’ which underlies the moral codes of all nations. The external duty changes from person to person according to our position in life. That which might be a duty in one condition would not be under other circumstances. All external duty is determined by a man’s relation to his external environment, hence it must necessarily remain relative. But ‘Subjective Principle’ can be universal. And that principle is summed up as “A duty which makes a person to go beyond his own little self and leads him towards the knowledge of his Infinite dimension”..
