El uso aristotélico de variables en lógica y sus supuestos ontológicos

A logical reading on Aristotle’s Organon discovers some inconsistencies in the text which have to be solved by reducing them to metaphysical decisions of the author, if they are not just identified as deficiencies in the exposition that should be corrected. The present article tries to display a line of reading paying attention to those so-called inconsistencies, in an attempt to understand them as specific steps in Aristotle’s research. In order to this goal it focuses on the exposition procedure of the Aristotelian figures: the use of variables, whose introduction by Aristotle has been celebrated all over logical tradition. An analysis of the distinctive and internal features in this procedure will allow us to link Aristotle’s logos research and the “being qua being” investigation, and to determine also –though in a negative way– the connection between this reading and the logical-traditional one on Aristotle’s Organon.
