  There are two Herculaneum treatises which treat the systematic basis of ethics. One is a kind of introductory treatment of Epicurean ethics, for which On Choices and Avoidances would be an appropriate title and which was probably written by Philodemus, who mentions such a work of his own (at PHerc. 1424.28.5; formerly called Ethica Comparetti after its first editor). The other is On Epicurus, a biographical, or rather hagiographical, work based largely on citations of the founder’s works (see further, Section 2.2.5.5).
