Schizophrenic Thought Disorder: A Model-theoretic Perspective Free

Model theory is a branch of mathematics that treats such abstruse questions as “is there another number system, different from 0,1,2, … that satisfies all the axioms of arithmetic?” (yes), and “can every mathematical hypothesis be proved true or false?” (no). It would not seem likely that any contribution could be made to our understanding of thought disorder in schizophrenia from such a remote quarter. The detailed results of model theory obviously will not apply; but I believe certain ways of thinking common in that field, but not in psychology, may help lead us toward explanations.¹
