Dialetheism Graham Priest

The article by Graham Priest, the contemporary logician and writer, seeks not only to deny the widely-held logical principle of non- contradiction (the principle that the conjunction of a proposition and its negation is impossible), but also to assert both the possibility and existence of contradictions. To affirm his position, he brings to light some paradoxical cases (propositions), which belong neither to any specific time nor place. He gives some examples from both western and eastern philosophies. On the other hand, he states that all arguments for the principle in question are prone to objections, and concludes that some contradictions are possible, or in other words, some propositions are both true and false. The author makes some remarks on Priest's view of contradictions, insisting that the conjunction of a proposition and is negation is impossible. To prove this, he examines some arguments given by Aristotle and considers them as hints at a self-evident matter instead of technical arguments. Elaborating on some propositions Priest uses to establish his position, the author concludes his discussion by stating that the impossibility of contradictions is self-evident to any mind or common sense, at any time or place. The only difficulty arises from the fact that it has been misconceived by some thinkers and much of its denial comes from the very misunderstanding.
