Twenty-two philosophers will argue with you.One coach will tell you why you lost.

Sit across from Socrates, Kant, Nietzsche, Arendt, and twelve others. Each argues their real positions in their own voice. A coach reads every exchange and shows you the stronger move.

Start your first debate See how it works

22 philosophers, 48 motions, free to start.

Immanuel Kant

1724-1804

Lying is never morally justified

If lying to a murderer saves my friend, then lying is obviously the right thing to do. Any theory that says otherwise is broken.

A debate partner who has actually read everything they wrote.

Every philosopher is built from their documented positions, their major works, and the objections they faced in life. Kant will not bend on lying to a murderer. Nietzsche will not apologize.

They know nothing after the year they died. Bring up the internet to Socrates and he will ask you to explain it, then reason about it the way he reasoned about the agora.

Set the terms: your side of the motion, free exchange or five structured rounds, and how hard they push. Gentle teaches as it argues. Ruthless grants nothing unearned.

The arena, with a coach at your shoulder

A structured debate against Nietzsche, round two of five. The coach has just read his reply.

Closing statement

Suffering has no intrinsic value. We admire people who overcame hardship, but that is admiration for the overcoming, not the pain. A child who learns resilience through love rather than trauma has lost nothing.

NietzscheOpening statement

“Admiration for the overcoming, not the pain.” Very well. But tell me what there is to overcome in a life arranged so that nothing resists you. You speak of the child raised in love as having lost nothing. I say she has lost the only teacher who does not flatter. The discipline that made every elevation of mankind was a discipline of suffering, of great suffering. Do you know of one strength that was not first a wound? Name it.

I can name one: curiosity. A well-fed, safe child explores further than a frightened one. Strength that comes from security is still strength.

Nietzsche is thinking

Rebuttal: answer their strongest point directly. Do not just restate your case.

Reply to Nietzsche...

Two and a half thousand years at one table

In order of birth, from the Daodejing to the Cold War. Each brings their own tradition, temperament, and the argumentative habits that made them who they were.

A coach who works between rounds and after the bell

During the debate, a short note after every exchange. Afterwards, a scorecard that reads the whole transcript. In between, drills for whatever the scorecard found.

48 motions, both sides argued properly

Every motion comes with four strong arguments for and four against, each with a real example, plus key terms, the traps debaters fall into, and where each philosopher stands.

Then the whole transcript is read back to you

Five criteria on a calibrated rubric. Every fallacy quoted with its turn number. A turn by turn account of the move you made and the stronger one you could have. The best thing you said. The openings you missed. A training plan for next time.

And a closing verdict from the philosopher, in character.

You argued with more care than most who take up the murderer at the door, and your distinction between deceiving and withholding was well drawn. But you never told me what makes a maxim universal, and until you do, your exceptions have no floor beneath them. Return with that, and I will listen again.
