Five Duties and Three Virtues

"The duties of universal obligation are five and the virtues
wherewith they are practiced are three. The duties are those between
sovereign and minister, between father and son, between husband and
wife, between elder brother and younger, and those belonging to the
intercourse of friends. Those five are the duties of universal
obligation. Knowledge, magnanimity, and energy, these three, are the
virtues universally binding. And the means by which they carry the
duties into practice is singleness.

"Some are born with the knowledge of those duties; some know them by
study; and some acquire the knowledge after a painful feeling of their
ignorance. But the knowledge being possessed, it comes to the same
thing. Some practice them with a natural ease; some from a desire
for their advantages; and some by strenuous effort. But the
achievement being made, it comes to the same thing."
