Roger Jones was an excellent teacher of Greek and Latin and learned in ancient Greek philosophy, to which his scholarly writing was devoted. His articles on Posidonius opposed Karl Reinhardt's thesis, which magnified Posidonius' influence on later Platonism and Stoicism. Jones inherited Shorey's view of the unity of Plato's thought, and in his turn had a great influence upon Harold Cherniss, his most illustrious student. In his later years he turned his attention to Plotinus and Neo-Platonism, but before his early death he had only published only one short article on the subject. He was also much interested in the comparative grammar of Greek and Latin and taught a graduate course in this subject.
