MENDEZ PINTO, Emilio. The Tractatus to the Rescue of Principia Mathematica: Ramsey and the Logicist Foundations of Mathematics. Crítica (Méx., D.F.) [online]. 2022, vol.54, n.161, pp.43-69.  Epub 05-Maio-2022. ISSN 0011-1503.  https://doi.org/10.22201/iifs.18704905e.2022.1346.

My aim is to expose the main difficulties that Frank P. Ramsey encountered in Principia Mathematica and the solution that, via the Tractatus Logico-Philosophicus, Ramsey proposed in this regard. I contend that the main difficulties that Ramsey encountered in Principia Mathematica were all related to Russell and Whitehead neglecting the logical form of mathematical propositions, which according to Ramsey must be tautological.

Palavras-chave : Russell; Wittgenstein; logicism; formalism; philosophy of mathematics.
