A.N Prior and the "Master Argument" of Diodorus

In this work the author analyzes the articles of three contemporary authors, that deal with the reconstruction of the "Master argument" of Diodorus. The attention is focused on the formal systems chosen, and on their dependency on the formalization of the concepts of time and space. Particularly, it is interesting to notice how the theory of relativity has influenced the twentieth-century debate on these themes, in the field of formal logic and of philosophy of language. Indeed the choice between temporalized or de-temporalized logic and between chronological or continuous time has a great influence, also on philosophical discussions as the ones on "free will" and metaphysical determinism, as we can see in this text.
