Teaching G{ö}del's incompleteness theorems

Abstract: The basic notions of logic-predicate logic, Peano arithmetic, incompleteness theorems, etc.-have for long been an advanced topic. In the last decades, they became more widely taught, inphilosophy, mathematics, and computer science departments, to graduate and to undergraduate students. Many textbooks now present these notions, in particular the incompleteness theorems. Having taught these notions for several decades, our community can now stand back and analyze the choices faced when designing such a course. In this note, we attempt to analyze the choices faced when teaching the incompleteness theorems.
