Harvey Friedman (born 23 September 1948)[1] is an American mathematical logician at Ohio State University in Columbus, Ohio. He has worked on reverse mathematics, a project intended to derive the axioms of mathematics from the theorems considered to be necessary. In recent years, this has advanced to a study of Boolean relation theory, which attempts to justify large cardinalaxioms by demonstrating their necessity for deriving certain propositions considered "concrete".
Jordana Cepelewicz (2017) profiled Friedman in Nautilus as "The Man Who Wants to Rescue Infinity".[8]
Friedman made headlines in the Italian newspaper La Repubblica for his manuscript A Divine Consistency Proof for Mathematics, which was later published in the book Ontology of Divinity.[9] In this manuscript, Friedman showed how, starting from the hypothesis of the existence of God (in the sense of Gödel's ontological proof), it can be shown that mathematics, as formalized by the usual ZFC axioms, is consistent.[10]
