Some Remarks about Modal Propositions and Their Meaning in Islamic Philosophy

Triadic matters (i.e necessity, possibility and impossibility) and modal propositions hold a special place in logics and Islamic philosophy. Meanwhile, due to the lack of a refined system of semantics, we are facing some ambiguities in some forms of modal propositions. This article analyzes these ambiguities after a general survey of modalities in logics and Islamic philosophy and a reference to some kinds of necessary propositions. In the second phase, there has been an attempt to utilize some of the modern systems of modalities, logics for giving suggestions about determining the rules of the semantics of these propositions.
