There are three friendships which are advantageous, and three which are injurious. Friendship with the upright; friendship with the sincere; and friendship with the man of much observation: these are advantageous. Friendship with the man of specious airs; friendship with the insinuatingly soft; and friendship with the glib-tongued: these are injurious.
ConfuciusThere is nothing more visible than what is secret, and nothing more manifest than what is minute.
ConfuciusA person of character takes as much trouble to discover what is right as the lesser men take to discover what will pay.
