It builds on an account of harmony for unilateral logic proposed by K ¨urbis and the observation that reading the rules for the connectives of bilateral logic bottom up gives the grounds and consequences of formulas with the opposite speech act. I formulate a process I call ‘inversion’ which allows the determination of assertive elimination rules from assertive introduction rules, and rejective elimination rules from rejective introduction rules, and conversely. It corresponds to Francez’s notion of vertical harmony. I also formulate a process I call ‘conversion’, which allows the determination of rejective introduction rules from assertive elimination rules and conversely, and the determination of assertive introduction rules from rejective elimination rules and conversely. It corresponds to Francez’s notion of horizontal harmony. The account has a number of features that distinguishes it from Francez’s. date: 2022-03 date_type: published publisher: NCL official_url: https://doi.org/10.4204/EPTCS.358.15 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2109690 doi: 10.4204/EPTCS.358.15 lyricists_name: Kurbis, Nils lyricists_id: NKURB54 actors_name: Kurbis, Nils actors_id: NKURB54 actors_role: owner full_text_status: public pres_type: paper series: EPTCS publication: NCL volume: 358 place_of_pub: Łódź, Poland pagerange: 202-215 event_title: 10th International Conference on Non-Classical Logics (EPTCS) book_title: Proceedings of the 10th International Conference on Non-Classical Logics editors_name: Indrzejczak, Andrzej editors_name: Zawidzki, Michal citation: Kürbis, Nils; (2022) Bilateral Inversion Principles.
