Bingo!"Powerful" being the operative word there.
He sounds like a guy that was trying to corrupt the youth with all his 'truth' nonsense, it's good they took care of him.
In the Republic, Plato speaks at length about Socrates and his ideas on education. Socrates gives what are sometimes conflicting accounts of education. In the first place he speaks about a guardian class of people, who will be instilled with only moral education from youth and will only know good as that which is familiar and see anything that is foreign and evil. Essentially a patriotic but xenophobic class. The other account of education he gives is that of philosophers, in which they are exposed to truth, and constantly seek the truth for themselves, which means at some point they must question that which they have been taught to ascertain if it was the truth of falsehood. This questioning of authority is what got brought about the accusations from the Athenian aristocracy that Socrates was corrupting the youth, which in turn led to his death sentence.“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.”
