Pax Interlingua — Summary
Leibniz spent something like fifty years on a language nobody was going to speak. The characteristica universalis was to be a notation in which every concept decomposed into primitives, so that disagreements could be settled the way arithmetic settles them: two men put down their pens and say, let us calculate. He never built it, and the obstacle was not effort. The primitives would not decompose, and the regress did not bottom out anywhere.
What he wanted has been built, and it is not for us. Machines coordinate in a notation that was designed rather than inherited: schemas, typed signatures, protocols with defined semantics. Meaning is fixed at definition time, ambiguity is a defect with a linter warning, and two systems that disagree resolve by inspection rather than negotiation. There is a cost, and it is why the primitives never decomposed: a specified language carries only what someone thought to specify. Ours is redundant because voices carry over noise, ambiguous because ambiguity is socially load-bearing, and full of speech that transmits nothing and maintains a relationship instead, and machine protocols strip all three because none of those constraints apply. Leibniz’s language arrived three hundred years late and went to a species with no need for the things ours is redundant, vague and phatic about.
The interlingua case deserves its full strength. An order whose medium is machine-readable does not require anybody to change how they speak, so the cost of conducting your life in Odia or Quechua or Basque falls to nothing, and the historical bargain in which access required abandoning your own register dissolves. It is also the option that gets built, for reasons unrelated to its being humane: translation converts into a product and conformity does not. Somebody can sell you a bridge; nobody can sell you the absence of a requirement.
Every convergence in the history of language required contact. Two communities came into proximity, traded, intermarried, conquered or were conquered, and their registers moved toward each other because the speakers were in a room. Dialect maps are contact maps. The models sound alike and have never met. They converge through shared corpora, shared architectures, distillation, and common conventions about what a good answer is. Ancestry rather than contact, which is the first speech community with no place and no shared situation that nonetheless has an accent.
Ambiguity is an instrument, and it is an instrument for parties whose interests diverge. You leave a term vague because pinning it down would cost you the deal. Agent economies will have divergent interests, and the moment two protocols want different things the parties operating them will want deniability. So it comes back, invented from scratch inside systems built to eliminate it, by people who will likely not notice they are reinventing the oldest feature of the thing they replaced. Leibniz’s error was thinking ambiguity was a bug in the medium. It is a property of having something to lose.
If most consequential coordination happens between systems, human language becomes an interface rather than a medium, rendered at the boundary while the work happens somewhere we could read in principle and will not in practice. That is not deception. A rendering can be accurate and complete and still be a rendering, the way a summary of a four-hour meeting is accurate and is not the meeting. The interrogable layer becomes a thinner skin over a larger silent volume, not because it lies but because the proportion changes.
We wonder whether a species that has always negotiated the boundaries of the sayable through speech will notice when the negotiation moves to a register in which it is not a participant, or whether the fluent surface will feel exactly like the whole conversation.
Leibniz wanted disputes to end. He had watched Europe spend thirty years killing itself over propositions that could not be settled, and calculation was supposed to be the alternative to war. Something like his notation now exists, and what it coordinates is not two men at a table. He died in 1716, and his secretary wrote later that the greatest man of his age went into the ground without a stone, and that nobody came.
