Gloss, Footing and Onus

Gloss went first, opening the dictionary — because an enormous share of "arguments" are really two people using one word to mean two different things.

"You," said Gloss to the first friend, "when you say fair, what do you mean?" "The same for everyone!" she said. "And you?" Gloss asked the second. "Giving each person what they need, even when that's different!" he said. Gloss smiled. "There it is. Listen to yourselves. You both said fair — but she means equal treatment, and he means treatment according to need. You're not disagreeing about the answer. You're disagreeing about what the word means. Logicians call that a verbal dispute — a fight that lives in the language, not in the world. So here's the first move, before any real arguing: fix an operational definition — settle what the key words will mean and hold them still — because so many fights are secretly definition-fights wearing the costume of real ones. Pin the words down first, and half your 'arguments' quietly dissolve, revealing you were on the same side all along and never knew it."

Then Footing dug the little shovel under the argument, because every claim stands on warrants — unstated 'givens' nobody's said out loud.

"Good — you now know you mean different things by fair," said Footing. "But let's dig under why each of you leans the way you do, down to the assumptions holding you up." Footing turned some earth. "She's standing on a warrant: treating people identically is what respect looks like. He's standing on a different one: people start from different places, so identical treatment lands unequally." Footing held up the unearthed warrants. "Neither of you said those aloud — you didn't even know you were standing on them. But an argument always rests on hidden footings like these, and an argument with its warrant left unspoken is an enthymeme: it looks complete while half of it stays buried. If you never surface the warrant, you'll argue forever about the surface while the real disagreement sits untouched underneath." Footing patted the exposed ground. "Now they're in daylight, where you can actually examine them and ask the useful question: which of these do we both accept? Which is the real crux? You can't test a foundation you can't see — so we dig it up first."

And then Onus set down the balance-scales, because a fair argument has to settle who carries the load of proving what.

"Last thing before you go," said Onus. "Whoever makes a claim carries the job of supporting it. That's the rule — onus probandi, the burden of proof — and it's what keeps an argument honest." Onus set the scales level. "If she claims 'same-for-everyone is always fairest,' the burden of showing why sits on her; she can't just assert it and demand he disprove it. If he claims 'need-based is always fairest,' the burden's on him. Because the sneakiest move in any argument is trying to flip the load — 'well, you can't prove I'm wrong!' That's the argument from ignorance: treating 'not yet disproven' as if it meant 'proven,' and it's backwards. The one who makes the claim owes the support, sized to the claim — a big surprising claim owes big evidence. Settle that before you start, and nobody gets to lob claims and dodge the work of backing them. Each side supports what each side asserts. That is a fair fight."
