Sobre la certeza: Bilingual Edition

In the middle of 1949, Wittgenstein spent some time in Ithaca, where Norman Malcolm revived his interest in G. E. Moore's work "In Defense of Common Sense", in which Moore claimed that common sense allows us to know with certainty that certain things are true. Wittgenstein had long been interested in this essay, and his reading of it motivated him to review it and write about this type of issue.

This book contains all the reflections that Wittgenstein jotted down about certainty during the last year and a half of his life. In these reflections, he outlines an effort to legitimize subjective certainty about the external world in comparison to the objective certainty of mathematics, a theme that would henceforth intensely occupy analytic philosophy and the controversies surrounding artificial intelligence.

These notes, written in four distinct periods, form a thematically coherent set, dedicated to proving the truth contained in common sense. They all remained in their first handwritten version, as the philosopher did not have time to rework them for publication.

As is customary in Wittgenstein's works, this volume presents a bilingual version, including the original German text.
