Peter de Rivo (Petrus) (c.1420 in Aalst – 1490 in Leuven) was a Flemish scholastic philosopher, teaching at the Old University of Leuven.
His views on future contingents were controversial, being opposed by Henry of Zomeren, also at Leuven (French: Louvain).George Henry Radcliffe Parkinson, Stuart Shanker, Routledge History of Philosophy (1999), p. 381. De Rivo went to Rome in 1472 to defend his views to Pope Sixtus IV; they were condemned in 1473.John Monfasani, Fernando of Cordova: A Biographical and Intellectual Profile (1992), p.36. Under pressure from the influence of Cardinal Bessarion to whom Henry had as secretary,Paul Oskar Kristeller, Itinerarium Italicum: The Profile of the Italian Renaissance in the Mirror (1975), p. 226. de Rivo retracted partially his opinions in 1473, and more fully three years later.Steven Vanden Broecke, The Limits of Influence: Pico, Louvain, and the Crisis of Renaissance Astrology (2003), p. 51. This meant that views going back at least to Peter Auriol, that future contingents lacked a truth value, had become heretical in the view of the Catholic Church.Stanford Encyclopedia of Philosophy, article Medieval Theories of Future Contingents
