It’s too late for me to digest this piece on Graham Priest’s Radical Dialetheic Logic and Reality, but I’m interested enough to bookmark it here.
The word dialetheism comes from the Greek δι (di- ‘twice’) and ἀλήθεια (alḗtheia ‘truth’). It’s the view that there are some statements which are both true and false. In other words, it’s the view that there can be a true statement whose negation is also true. In the literature, these statements are called “true contradictions” or (to use Graham Priest’s neologism) dialetheia.— Paul Austin Murphy
