Abstract:
Diodorus Cronus, the Megaric Logician, in an attempt to define possibility and necessity, formulated an argument which after him was known as Diodorus Cronus Master Argument. According to extant historical accounts, Master Argument consists of three premises which according to Diodorus form an inconsistency, so that results in the rejection of Aristotelian notion of possibility and establishment of determinism. But the argument itself i.e. how three premises of the Master Argument form an inconsistency, has been lost. Therefore a number of logicians has decided to reconstruct the Master Argument and thereby reveal its inner structure in order to evaluate its validity.
On the other hand, due to the fact that the Master Argument defines possibility and necessity in terms of temporal concepts like past and future, the relation between time and modality acquires special importance in this argument. In this research, we will try to analyze these two aspects of Diodorus Cronus Master Argument in a satisfactory manner
