The desire to represent first order theories in a computer in a feasible way requires the facility to discuss meta mathematical notions. Using metamath e matics willeventually allow to construct systems which can form<Jlly discuss how they reason. In thi s paper we present twu different first order axiomatizations of the metamathematics of the logic which FOI. (First Ordc•r Logic proof checker) checks and show sevt·ral proofs using each one. The difference betwl'en the axiomatizations is that one defines the metamathematics in a raany sorted logi c and the otlwr docs not. Proofs arc then compared and used to discuss the adequacy of sorae FOL features.","doi":null,"url":"https://ijcai.org/proceedings/1975/1","pdf":"https://ijcai.org/proceedings/1975/0001.pdf","markdown":"https://ijcai.org/proceedings/1975/1.md","bibtex":"https://ijcai.org/proceedings/1975/bibtex/1","volume":{"slug":"1975","title":"Proceedings of the Fourth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1975","url":"https://ijcai.org/proceedings/1975/","year":1975,"location":"Tbilisi, Georgia, USSR","dates":"","editors":"Patrick Winston and Carl Hewitt","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Mathematical and Theoretical Aspects of A.I","track":"Mathematical and Theoretical Aspects of A.I","number":1,"pages":{"first":1,"last":7},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
