The Truth Contract

Section XI of TOK4ALL, first draft, August 2026. One section of fifteen; a work in progress.

Most of what you know, you did not find out. Someone handed it to you — a parent, a teacher, a book, a screen. We don’t know things on our own; we depend upon reliable knowledge being transmitted to us. Which raises the question this section is about: what do we owe each other, as givers and receivers of knowledge?

Here is the claim: there is an implicit understanding across all humans that it is very important to produce and share reliable knowledge — and not doing so breaks the contract. We call it the truth contract. Nobody signed it. There’s no document, no sacred tablet on the mountain with the rules. And yet you’re already bound by it, and so is everyone you know. Let’s see why.

A meeting before you were born

Philosophers have long imagined that societies rest on a social contract — Rousseau and Hobbes imagined humans implicitly agreeing on certain rules: don’t kill other people; respect each other’s property. The philosopher John Rawls gave the modern version, and it comes as a thought experiment you can actually run.

Imagine a meeting, held before any of us were born, to decide on the rules we would follow after landing on Earth. Everyone at the meeting has gotten the memo: you’re going to be born, but you don’t know where. You don’t know the location, the race you’ll be born into, your gender, your social class, how you’ll be embodied — how tall, what features, what health. You might be born into a wealthy hedge-fund family atop a Manhattan skyscraper. Much more likely, you’ll be born somewhere far less comfortable — perhaps, at the extreme, into the lowest caste of a rigid society.

Rawls asked: what rules would these souls agree on, not knowing where they’d end up? His answer: fairness. Equality and justice built in from the start. Not because the souls are generous — because they’re rational. Wouldn’t you want a fair shot across the board, when you landed on Earth and it could be anywhere?

That’s the social contract. Now run the meeting again — because there’s a second item on the agenda. This one is ours: What rules should govern how humans seek, share, and evaluate knowledge?

Remember: you don’t know whether you’ll be the scientist whose findings get dismissed, the patient who needs accurate medical information for a life-or-death decision, the voter who depends on reliable news, or the child whose education is built on falsehoods. Any of these could be you. So — what truth contract do you vote for?

The two rules

Behind the veil, the vote converges on two rules — simple enough to memorize.

Rule One: For something to count as knowledge, it must be reliably produced. It has to come from reliable sources — observation done carefully, reasoning done honestly, testimony traced to someone in a position to know.

Rule Two: Share only reliable knowledge — and if you’re not sure it’s reliable, say so. Qualify it. “I think.” “I haven’t checked.” “Don’t take my word.”

That’s the whole contract. Three philosophers have put its spirit in three ways, and you can vote on each: Grice — only share what you believe true and have adequate evidence for (Yay or Nay?). Goldman — build your society’s schools, media, and courts to spread truths and starve falsehoods (Yay or Nay?). Kornblith — be epistemically responsible: do all you can to produce true beliefs (Yay or Nay?). Behind the veil, sensible souls vote Yay three times — not because they’re saints, but because they might be the ones who need the truth most.

The luxury of lies

Is the truth contract real — did humans actually follow it? Look around at what we can do. Human society would not be in the position it’s in right now — where we can send rockets to the moon, study things at the quantum level, avoid diseases that once had incredible fatality rates — without a truth contract in place. Science is where the contract has been most firmly enforced: procedures for observation and hypothesizing, protocols for testing, statistical analysis, peer review — an entire machinery for keeping Rule One and Rule Two. But beyond science — in law, in schooling, in everyday cooperation — we are where we are because reliable knowledge was produced and shared.

Which puts today’s flood of misinformation in a strange light. Here is the observation: it’s a luxury that all this misinformation and disinformation is out there while society still functions — because society is built upon a base of reliable knowledge already. Every day we’re enjoying the fruits of the truth contract without even thinking about it. A developing society that spread lies the way we now can — it would not have gotten very far. Human progress would not have been possible in the absence of a truth contract. It is only because our ancestors mostly kept it that we can afford to break it. It’s a luxury to be able to spread lies.

The bad directions

Too abstract? Zoom all the way in. You stop to ask for directions. The person doesn’t actually know — but instead of saying so, they point confidently. You end up exactly opposite of where you wanted to go. Now notice what they could have said, at no cost: “I’m not from here, but I think it’s over that way.” One qualifier — Rule Two — and you could have discounted it and waited for the next person. That tiny moment is the whole contract in miniature. Can you think of a time someone shared unreliable information with you — knowingly or not — and it cost you? Now imagine a society where that was common, right at its beginning. What happens? Nothing good.

An aside, from someone who was there

In the early days of the World Wide Web — 1994 through the late nineties — it was hoped by Internet evangelists, myself included, that the Internet would replace the lost public square that thinkers like John Dewey mourned: communities that kept the truth contract, that decided and solved problems together. And in many ways it delivered — from world-changing collaborations down to the quilting clubs my sister-in-law joined, people of joint interest sharing what they know. But as we know all too well, the same medium turned out to be the most powerful lie-spreader ever built. We were naive — I was naive. We never got the ideal epistemic community. We got something that could still become one, or its opposite. Your generation holds that vote.

“But isn’t it all relative?”

A good critical thinker considers objections — so here’s the strongest one. Societies differ enormously. Isn’t the “truth contract” just one culture’s rules? Maybe there are no universal epistemic values at all.

Two replies. First, the logical one: if Aristotle is right that all humans desire to know — and value knowing both for its own sake and for what it makes possible — then every society needs ways of producing, acquiring, and sharing knowledge that actually work. A society that routinely shared unreliable knowledge would fare exactly as well as one that routinely permitted killing and stealing. The contract isn’t optional equipment; it’s survival equipment.

Second, the empirical one — and you can test it yourself. Set the traditions side by side: Western, Confucian, Buddhist, African. Look for the values they share about knowledge and wisdom. They converge — honesty in judgment, respect for the wise, care in testimony — tradition after tradition, ocean after ocean. The exercise Ethics Across the Globe, in the exercise wing of this book, lets you run this discovery at a card table.

The contract, when the chips are down

Let’s end where the stakes live. To flourish as individuals and as a society, we follow both contracts: the social contract — the basic rules for getting along, like not harming each other — and the truth contract — the rules for generating, acquiring, and sharing knowledge. The two stand or fall together, and you feel it most when the chips are down: when the diagnosis matters, when the vote matters, when the bridge either holds or doesn’t. In those moments nobody wants comforting information. Everybody wants reliable information. The truth contract is just the agreement to be, for each other, the kind of source we all pray for when it counts.

So before you speak, post, forward, or share — one question from the Battery, the seventh: Do I know this well enough to pass it on?

That’s the contract. You’ve already signed.
