Content of the most Elemental Notion of Human Nature

Dr. Livingstone mentions that the only addition he felt called upon to make to the moral code of certain of the Zambesi tribes (however little they observed their own law) was, that a man should not have more than one wife.  “Evil speaking, lying, hatred, disobedience to parents, neglect of them,”[1]  were all known to be sin by these dark peoples whom civilized or Christian teaching had never before reached.  Not only is a sense of duty common to mankind, but the deeper consciousness of God, however vague such consciousness may be.  And all this and much more goes to make up the most elemental notion of human nature.
