Abstract

From XIX Century, the controversy over the authenticity of the Metaphysics’ Kappa has been a constant in the context of studies on the Metaphysics. In regard to the redaction of the aporias of K 1-2, the differences in style and content are remarkable. However, after analyzing the differences, we can assert quite safely that the author of K 1-2 is Aristotle. Indeed, K 1-2 do not contains non-Aristotelian philosophy in approach of the aporias nor in the doctrines involved in them. In this sense, the differences may be explained by the renewed interest of Aristotle for the supersensible, in the face of its research on Λ 6-10. Secondly, with respect to the redaction of aporias, researches on style and morphometry show that the use of some expressions change significantly from one work to another, so differences in style, use of particles and unusual expressions in K 1-2 can be understood as normal.
