Alexandru Anghelescu

The text follows Dante Alighieri through the medieval logic: strong and weak disjunction, conjunction, anaphora and definite descriptions, the liar paradox, Russell’s paradox and the puzzle of the Trinity, 2 valued and 3 valued propositional logic, temporal quantifications over relevant performing.Dante's Paradise is not a christian one,but one of fraternity,where all humans can find a place(including muslims,indians...) as long as they follow love;to avoid censorship(only 1 Pope seemingly is in his paradise(Luther used it))he used the Liar paradox at Pg.3 making Aristotle unable to understand his Metaphysica Lambda;this makes the Limbo a reader's homework and Heidegger's dasein a wrong reading of Dante, while Russell read Dante for his definite descriptions and Aristotle and Dante for his paradox;Beatrice is the philosophy and not Virgilio as many still believe;Dante knew and used the solution to the Trinity Paradox

Do other earthly forms of life evolved to the level of intelligent life? Cancer and resistance to antibiotics obliged to ask this question. Signs of intelligence are found at its simplest levels. We try to see if logic is used at these levels. Peter of Spain’s suppositio materialis is applied to the chemical signals of cells. Dynamic Logic is used to understand these chemical communications. <System of communications> is used, instead of “language”. The development of life appears as the development of an axiomatic system. The rights of unborn humans and God’s rights over His own creation appear as the most powerful arguments for conservationism
