For example, how might an arbitrary statement like "Scholars believe that professional competence of a teacher is a prerequisite for improving the quality of the educational process in preschools" be put in a lean-like language? What about "The theoretical basis of the October Revolution lay in a development of Marxism, but this development occurred through three successive rounds of theoretical debate"?
Or have I totally misunderstood what people mean when they say that developments in automatic theorem proving will solve LLM's hallucination problem?
It can also be achieved informally and in a fragments way in barely-mathematical disciplines, like biology, linguistics, and even history. We have chains of logical conclusions that do not follow strictly, but with various probabilistic limitations, and under modal logic of sorts. Several contradictory chains follow under the different (modal) assumptions / hypotheses, and often both should be considered. This is where probabilistic models like LLMs could work together with formal logic tools and huge databases of facts and observations, being the proverbial astute reader.
In some more relaxed semi-disciplines, like sociology, psychology, or philosophy, we have a hodgepodge of contradictory, poorly defined notions and hand-wavy reasoning (I don't speak about Wittgenstein here, but more about Freud, Foucault, Derrida, etc.) Here, I think, the current crop of LLMs is applicable most directly, with few augmentations. Still a much, much wider window of context might be required to make it actually productive, by the standards of the field.
Generally, I think many people who haven't studied mathematics don't realize how huge the gulf is between "being logical/reasonable" and applying mathematical logic as in a complicated proof. Neither is really of any help for the other. I think this is actually the orthodox position among mathematicians; it's mostly people who might have taken an undergraduate math class or two who might think of one as a gateway to the other. (However there are certainly some basic commonalities between the two. For example, the converse error is important to understand in both.)
But logic is very relevant to "being logical/reasonable", and seeing how mathematicians apply logic in their proofs is very relevant, and a starting point for more complex applications. I see mathematics as the simplest kind of application of logic you can have if you use only your brain for thinking, and not also a computer.
"Being logical/reasonable" also contains a big chunk of intuition/experience, and that is where machine learning will make a big difference.
