The Two Bones of Intuitionistic Logic

In the unit type, we call trivial in pi, because it corresponds to sort of trivial theore, or a trivial statement. And these sorts of things saing like frall an exists and nd is really what you get from adding dependent types to the mix. But if you want to get other logics, you can also figure out how to run those as programes. So for example, a lamda x f of x is the same function as just f on its own
