Kosta Došen argued in his papers Inferential Semantics (in Wansing, H. (ed.) Dag Prawitz on Proofs and Meaning, pp. 147–162. Springer, Berlin 2015) and On the Paths of Categories (in Piecha, T., Schroeder-Heister, P. (eds.) Advances in Proof-Theoretic Semantics, pp. 65–77. Springer, Cham 2016) that the propositions-as-types paradigm is less suited for general proof theory because-unlike proof theory based on category theory-it emphasizes categorical proofs over hypothetical inferences. One specific instance of this, Došen points out, is that the Curry-Howard isomorphism makes the associativity of deduction composition invisible. We will show that this is not necessarily the case.
