Humanity Defined by Five Relational Duties
The primer opens by claiming that humans are the most valuable of all beings because they have the Five Relationships, not because of intelligence or strength. These are affection between father and son, righteousness between ruler and minister, distinction between husband and wife, order between elder and younger, and trust between friends. A person who fails these obligations is described as little different from an animal, so human status is earned through conduct inside relationships rather than given by nature.
