Riassunto di Protagora
A chi è rivolto
For anyone curious about education, ethics and how to argue well, and for first-time readers of Plato who enjoy lively debate, vivid characters and humor.
Che cos’è questo libro
Protagoras is a dialogue written by Plato in the early fourth century BC, a generation after the Athens it describes. Socrates tells a friend about a day when he met the most admired teacher of his time, the sophist Protagoras of Abdera. The scene is the house of a rich Athenian named Callias, crowded with famous guests. The talk begins with one question that sounds simple. Can goodness be taught, and if it can, who is able to teach it?
You get a lively argument in which both men end up near the position the other began with. You also get a founding story about human beings, a quarrel over how to hold a discussion, a playful reading of a poem, and a bold claim that wrong action is a mistake of knowledge. Plato wrote it as a drama, with jokes, moods and sharp portraits. Behind it sits a question that never went away. Is the good something you learn, like a craft, or something you are born with? Let us start with the young man who woke Socrates before dawn.

Be careful what you buy for your mind
The dialogue opens in the dark. A young man named Hippocrates bangs on Socrates' door before dawn with news that Protagoras is in town. He is burning to become his student, and he wants Socrates to introduce him.
Socrates does not say no. He asks a question instead. If you went to a doctor or a sculptor for lessons, you would expect to become a doctor or a sculptor. So what will Hippocrates become if he studies with Protagoras? Hippocrates blushes, and the best he can say is that he will become a clever speaker. Socrates presses him to name the subject of that cleverness, and Hippocrates cannot.
Then Socrates makes his main point about the opening scene. A sophist, he says, is a merchant who sells goods for the soul. Food can be carried home in a jar and tested before you eat it. Teaching goes straight into the mind, and once learned it cannot be returned. So you should take advice from someone wiser before you buy.
The lesson reaches well beyond ancient Athens. We still pay for courses, coaches and books that promise to improve us. Plato asks us to check what is really being offered and what it will do to us. The two men walk off to Callias's house, and the scene is set for the contest.
