Stanley H. Rosen, 84, of Philadelphia, a scholar and emeritus professor of philosophy, died Sunday, May 4, of pneumonia at Cathedral Village in Roxborough.
Dr. Rosen was an influential writer and teacher known for his thinking and writing on Plato, Heidegger, Hegel, and Nietzsche.
He served on the faculty of Pennsylvania State University for 38 years and Boston University for 14 years before retiring to Philadelphia to be near family.
He was the author of 20 books, recipient of numerous honors, and a former president of the Metaphysical Society of America.
"For those of us who knew him well, his death is a remarkable loss," David Roochnik, chair of Boston University's philosophy department, wrote on the university's website. "He was an extraordinary person and thinker, and we will cherish his memory."
