“All the most reasonable teachings of human wisdom concerning justice are summed up in that famous adage: Do unto others that which you would that others should do unto you; Do not unto others that which you would not that others should do unto you. But this rule of moral practice is unscientific: what have I a right to wish that others should do or not do to me? It is of no use to tell me that my duty is equal to my right, unless I am told at the same time what my right is.”
