Abstract

Many rules of Ancient Logic need the existence of the subject, and this existence can be either added into the propositions’ structures or regarded as a part of the rules, as enthymematic premise. The two approaches can be named “intra-proposition” and “intra-rule” commitments. The first thinkers who used the latter explicitly are Avicenna and Nasir Al-din Al-Tousi, respectively, on OBVERSION and CONTRAPOSITION. Al-Tousi added the proviso of the existence of the subject as not only the premise of CONTRAPOSITION, but also as its conclusion. In contemporary period, Al-Muzaffar added INVERSION to the body of Ancient Logic’s rules. INVERSION can be validated by none of the commitments mentioned: Avicennian or Al-Tousian intra-proposition and intra-rule. We show that it can be defended by no other means.
