 L3/M3 refer to the patterns displayed by grammatical and moral intuitions. In the case of language, native speakers can recognize grammatical and ungrammatical constructions relatively easily, but typically cannot articulate the rules underlying these intuitions. In the case of moral grammar, the analogy claims, the same is true: we produce moral intuitions effortlessly without being able to explain the rules underlying them. Indeed, in both cases, the rules underlying the judgments might be quite esoteric and difficult for native speakers to learn and understand.
