Some, for example, are held to be generous, and others miserly. Some are held to be benefactors, others are called grasping, some cruel, some compassionate, one man faithless, another faithful, one man effeminate and cowardly, another fierce and courageous, one man courteous, another proud, one man lascivious, another pure, one guileless, another crafty, one stubborn, another flexible, one grave, another frivolous, one religious, another sceptical, and so forth.
