Ernst von Glasersfeld

Ernst von Glasersfeld (March 8, 1917 in Munich – November 12, 2010 in Leverett, Franklin County, Massachusetts) was a philosopher, and Emeritus Professor of Psychology at the University of Georgia, Research Associate at the Scientific Reasoning Research Institute, and Adjunct Professor in the Department of Psychology at the University of Massachusetts Amherst. He was a member of the Board of Trustees, American Society of Cybernetics, from which he received the McCulloch Memorial Award in 1991. He was a member of the Scientific Board, Instituto Piaget, Lisbon.
Von Glasersfeld coined the term radical constructivism and spent large parts of his life in Ireland (1940s), in Italy (1950s) where he worked with Silvio Ceccato, and in the US. Elaborating upon Giambattista Vico, Jean Piaget's genetic epistemology, Bishop Berkeley's theory of perception, James Joyce's Finnegans Wake, and other important texts, von Glasersfeld developed his model of Radical Constructivism, which is an ethos shared by all of these writers to one degree or another.
Ernst von Glasersfeld’s literary estate is administered and curated at the Ernst-von-Glasersfeld-Archive at the University of Innsbruck.
