Whom do I call educated? First, those who manage well the circumstances they encounter day by day. Next, those who are decent and honourable in their intercourse with all men, bearing easily and good naturedly what is offensive in others and being as agreeable and reasonable to their associates as is humanly possible to be... those who hold their pleasures always under control and are not ultimately overcome by their misfortunes... those who are not spoiled by their successes, who do not desert their true selves but hold their ground steadfastly as wise and sober-minded men. – Socrates.
