Mark Amadeus Notturno

Mark Amadeus Notturno is an American philosopher specializing in epistemology, philosophy of science, and philosophy of logic. He was a close friend and associate of Sir Karl Popper and, in addition to writing four books about his philosophy and editing two of Popper's own books, has lectured on his views about science and open society in over twenty countries in the Americas, Europe, and Asia. He is currently a Fellow of the Interactivity Foundation (IF), where he has conducted governance projects and published reports on 'Privacy', 'Science', 'Property', 'Democratic Nation Building', 'Teaching Methods', 'The Future of Higher Education in Post-Communist Countries', 'The Future of Governance in Transitional Societies', 'Money, Credit, and Debt', 'The Future of Employment', and 'Global Responsibility for Children'. He has also conducted IF Teacher Training Programs in Student-Centered Discussion courses, and he regularly facilitates IF Online Discussions pertaining to public policy issues. He is currently conducting an IF project on 'The Future of Free Speech'.

Dr. Notturno is the author of Hayek and Popper: On Rationality, Economism, and Democracy (2015); On Popper (2002); Science and the Open Society (2000); Objectivity, Rationality and the Third Realm: Justification and the Grounds of Psychologism (1985), and numerous articles on Popper’s work. He is also the editor of Perspectives on Psychologism (1989), and the editor of Sir Karl Popper’s The Myth of the Framework (1994) and his Knowledge and the Body-Mind Problem (1994).

Mark earned his doctorate in philosophy from Columbia University and held teaching and research positions at several universities and foundations before joining IF. From 1994 through 1999, he was the director of the Soros and Ianus Foundations’ ‘Popper Project’. He lived in Budapest and Vienna during this time, from where he organized and directed over forty international workshops, seminars, and summer schools for philosophers and scientists in the countries of the former Soviet Union and socialist bloc. These programs, which focused upon problems pertaining to the philosophy of science and the transition to open society, were distinguished by their round-table discussion format. Their participants included more than a thousand faculty and researchers from these countries’ universities and research institutes, as well as representatives from their ministries of education. After returning to the United States and joining IF, Notturno continued to work on Popper’s philosophy, including issues arising out of the Supreme Court’s adoption of the concept of ‘falsifiability’ in its 1993 Daubert decision; on the application of Popper’s epistemology to knowledge management and to the problem of medical errors; and on Popper's intellectual differences with F.A. von Hayek regarding rationality, democracy, and economism. He conducts a regular online international seminar on 'The Future of Science and the Open Society'. And he is currently working on a book, Karl Popper's Introduction to Scientific Methods, based upon the lectures that Popper gave to his first year students at the LSE.

Mark currently lives in Washington, D.C. with his wife Ieva.
