Socrates
Be kind, for everyone you meet is fighting a hard battle.
+
Socrates
There is only one good, knowledge, and one evil, ignorance.
+
Socrates
Mankind is made of two kinds of people: wise people who know they're fools, and fools who think they are wise.
+
Socrates
Are you not ashamed of caring so much for the making of money and for fame and prestige, when you neither think nor care about wisdom and truth and the improvement of your soul?
+
Socrates
The children now love luxury; they have bad manners, contempt for authority; they show disrespect for elders and love chatter in place of exercise. Children are now tyrants, not the servants of their households. They no longer rise when elders enter the room. They contradict their parents, chatter before company, gobble up dainties at the table, cross their legs, and tyrannize their teachers.
