Herillus
（
*(/Hillos), of Carthage, a Stoic philosopher, was the disciple of Zeno of Cittium.
He did not, however, confine himself to the opinions of his master, but held some doctrines directly opposed to them.
He held that the chief good consisted in knowledge (
ἐπιστήμη).
This notion is often attacked by Cicero, who in two places speaks of his tenets as "jamdiu fracta et exstincta," and as "jampridem explosa."
He wrote some books, which, according to Diogenes, were short, but full of force. Their titles were
Περὶ ἀσκήσεως,
Περὶ παθῶν,
Περὶ ὑπολήψεως,
Νομοθέτης,
Μαιευτικός,
Ἀντιφέμων διδάσκαλος,
Διασκενάζων,
Εὐθύνων,
Ἑρμῆς,
Μήδεια,
Διαλογοι,
Θέσεις ἠθικαί. Cleanthes wrote against him. (
