The nobler sort of man emphasizes the good qualities in others, and does not accentuate the bad. The inferior does the reverse. . . . The nobler sort of man pays special attention to nine points.

When in doubt, he is careful to inquire; when in anger, he thinks of the consequences; when offered an opportunity for gain, he thinks only of his duty.
