ABSTRACT
Herillus of Carthage is frequently referred to by Cicero as teaching doctrines hardly distinguishable from those of the Academy, in that he made knowledge the highest good. He appears to have supported Zeno vigorously as to the doctrine of 'comprehension'; and if on this subject he was worsted for the moment by Persaeus. Aristo was however once more in agreement with Stoic doctrine when he maintained the unity of virtue. An eminent pupil of Aristo was Eratosthenes of Cyrene, the grammarian, whom he won over from the Cyrenaic school. Alone amongst the hearers of Zeno, Dionysius of Heraclea abandoned his principles, and went over from the camp of virtue to that of pleasure. Being detained there by an accident, he employed his time in giving lectures on literature; and his pupil Panaetius was destined to introduce Stoicism to Roman society. Diogenes of Seleucia and Antipater of Tarsus were both men of eminence in the history of Stoicism.
