... may be helpful to think about how your definition would work if you did use append (for difference lists). 2. For this question you will write straightforward translations of natural deduction and the sequent calculus for minimal logic (there is no rule for falsehood) for pure propositions (no quant ...

On the other hand, (2) without (1) sends us down an infinite path of something eating something eating something and so on, with nothing telling us when to stop. Recursive definitions ...
