It is natural for every person to have a master, from a beggar to a king. There is no soul on earth who has not someone under whose control and command he is expected to act: in school under the teacher, in the army under the commanding officer, in the workshop under the foreman, in a nation under the king or president. There is no aspect of life that exempts man from this. Thus it is wise to act towards one's own superior with the consideration one would expect from one's inferior.
