On the crisp fall night of October 27, 2026 in Milton, Massachusetts, John Ferguson Heil passed on peacefully surrounded by family. He was 83 years old.

John is survived by his wife of 46 years, Lilian Harrison Hagan Heil, his seven children (Katherine Heil Hamilton, John F Heil Jr., Henry F Heil, Lucy Heil Homiller, Mark H Heil, Augustine (Gus) S Heil, and Lilian R Heil), eleven grandchildren (Alison, Ian, Henry, James, Ella, Andy, Maggie, Claire, Jack, Frances, George), and one great-grandchild (Leon).

An only child, John was born in Washington, DC on January 4th, 1943 to Colonel John Henry Heil Jr. and Lucy C Ferguson Heil. As an army brat, he started traveling the world at a young age. He never stopped exploring, always looking for his next horizon.

John married his high school sweetheart and had four children while putting himself through undergraduate studies at Randolph Macon College before earning his PhD in Philosophy from Vanderbilt University in 1970. He went on to teach at Randolph-Macon Woman’s College where he met his true soulmate. John and Harrison were married in 1980 and built an enduring partnership that took them on a lifelong adventure around the world and back many times over, often with their three children. In addition to RMWC, John taught at Virginia Commonwealth University; Davidson College; Washington University in St. Louis; and Durham University, (England). Research affiliations during sabbatical and fellowship leaves of absence included the University of California, Berkeley; Oxford University (England); and Monash University (Australia). A piece of his heart remains in these places and with the people there who inspired and challenged him.

In addition to being a beloved father and husband, John Heil was a philosopher’s philosopher, merging teaching and research to write numerous influential books and papers, including From an Ontological Point of View (2006), The Universe as We Find It (2012), Appearance in Reality (2021), and What Is Metaphysics? (2021). He wrote and regularly updated Philosophy of Mind: A Contemporary Introduction (1998), and First-Order Logic: A Concise Introduction (1994) for use in introductory philosophy classes. From ancient philosophical problems about the nature of being to modern questions about quantum theory, he addressed every conundrum with his signature rigor, clarity, and originality.

John was an active member of the global philosophical community, serving many years as the North American editor for the Philosophical Quarterly before becoming the inaugural editor of the Journal of the American Philosophical Association. Recent honors include election to the Australian Academy of the Humanities (2020), a Fulbright Australia Fellowship (2019), and a Guggenheim Fellowship (2018).

John approached his whole life the way he approached philosophy: with intensity and unwavering commitment to his goals. From folk music to Australian nightly news to trains (real and model), he unabashedly gave his all to whatever he set his sights on. An avid runner, he qualified for the Boston marathon multiple times but never ran it because he taught on Mondays. He kept up this pace throughout his life, most recently with a personal trainer using bands, weights, and battle ropes three times a week. He loved baseball, playing competitively well into adulthood and instilling in his family a passion for all facets of the game. John remained active until the end: just weeks before he left us, he attended batting practice at a Red Sox game while traveling to lead a graduate workshop on his latest book, Appearance in Reality.

John passed his determination and tenacity to all seven of his children, who have found success in a wide variety of fields. He frequently reminded them that he didn’t care what type of work they did as long as they gave their all to something that “utterly fulfilled” them. He believed each one of his children had the capacity to do great things, and provided them with the resources and skills to do so. The diversity of paths taken by his children speak to his unconditional support for them to pursue what interested them the most. As a father he imparted drive, grit, and an uncanny understanding of classic philosophical problems in his kids from a young age. He also loved reading to them, coaching baseball fundamentals from the time they could walk, and diverting them with the Kinston Trio on long car rides.

John Heil was a singular man and old-school teacher who touched innumerable lives over his long life and career. He worked hard every day of his life to be the best possible version of himself and to help others do the same. He leaves behind an extraordinary body of philosophical work, generations of students and colleagues influenced by his teaching and scholarship, and a family that carries forward his curiosity and discipline. His legacy lives on not only in his writings and ideas, but also in the many people he encouraged to think independently and strive for excellence. Those who knew him are better for it, his passion and drive were infectious.

A celebration of life will occur at a later date. In lieu of flowers, we ask that donations be made to Good Sports, an organization that brings baseball and other sports to high need communities. https://gofund.me/2b1da8719
