In this paper I question this association. Specifically, I claim that Frege and Peano developed significantly different conceptions of a logical calculus. First, I claim that while Frege put the systematisation of the notion of inference at the forefront of his construction of an axiomatic logical system, Peano modelled his early logical systems as mathematical calculi and did not really attempt to justify reasoning. Second, I argue that in later works on logic Peano advanced towards a deductive approach that was closer to Frege’s standpoint.engjournal article2295-5836https://dx.doi.org//10.2143/LEA.253.0.3289334https://poj.peeters-leuven.be/content.php?url=article&id=3289334https://produccioncientifica.ucm.es/documentos/697e9e134f95b66d0e7b4b15restricted access16FregePeanoInferenceDeductionLogical calculusLógica (Filosofía)1103 Lógica General
