Eudemus of Rhodes was a pupil of Aristotle in the second half of the fourth century BCE. When Aristotle died, having chosen Theophrastus as his successor, Eudemus returned to Rhodes where it appears he founded his own school. His contributions to logic were he took issue with Aristotle concerning the status of the existential and "is, and " and together with Theophrastus he made important contributions to hypothetical syllogistic and modal logic. He wrote at length on physics, largely following Aristotle, and took an interest in animal behavior. His histories of geometry, arithmetic, and astronomy were of great importance and are responsible for much of what we know of these subjects in earlier times.Volume 11 in the series Rutgers Studies in Classical Humanities is different in that it is composed entirely of articles that discuss Eudemus from a variety of viewpoints. Sixteen scholars representing seven nations have contributed essays to the volume. A special essay by Dimitri Gutas brings together for the first time the Arabic material relating to Eudemus.

For it enlarges the scope of the information available on this author, highlights the need of, and paves the way to, a new critical edition of the Greek fragments of his works, and provides a clearer view of his life, thought, sources and influence.
