Retorsion
Showing that denying a claim undercuts the act of denying it — you have to use logic to reject logic. TAG’s strongest form is retorsive. This corpus distinguishes that from merely listing ethics as a topic a worldview must ground: inventory is not yet retorsion.
From Latin retorquere, “to turn back” — turning an objection back on the objector.
Retorsion turns an objection back on the objector: the act of denying the claim already uses what the claim says is necessary. The textbook case is logic. You cannot coherently argue that argument is impossible. TAG's strongest form is this shape.
OTC-022's dual-label exists because people keep collapsing two different claims. Finding A: Dyer-shaped TAG *practice* treats ethics as a load-bearing transcendental domain. Finding B: categorical moral obligation has not been shown to be a retorsive precondition the way logic has — Sorem's TAG lists name knowledge, rationality, logic, arguments. Apel and Gewirth attempt moral retorsion in the secular literature; Enoch's shmagency objection is the standing defeater, and a theistic version of the same move inherits it. Gate A on OTC-022 retained the old categorical burden. Incomplete retorsion is not "TAG doesn't do morals."
The mistaken everyday reading is "gotcha" or "hypocrisy." Retorsion is a claim about performative self-undermining, not about the speaker's character.
