Sesto Empirico, Roderick Chisholm e il problema del criterio

This paper analyzes a single theoretical aspect of the so-called «problem of the criterion», which was for the first time formulated by Sextus Empiricus in his Outlines of Pyrrhonism. It stresses the circularity of arguments designed to conclusively justify the criterion of justification postulated by a theory of knowledge. Formulated in this manner, this problem can be defined a metaepistemological one. Roderick Chisholm has tried to deal with it in a manner that maybe misses the point of Sextus’ argument
