Abstract
This paper is a first publication on my ongoing research on the sources of the extant doxographies on Stoic ethics. It argues that there are identifiable traces of a copy-and-paste strategy in the “Outline of Stoic Ethics” generally attributed to Arius Didymus and transmitted in Johannes Stobaeus’ Anthology. The author of the Outline took extant doxographic texts and supplemented it by inserting additional material. The editing process also resulted in transpositions, omissions, and rewriting to connect the original material with the accretions to it. This kind of source criticism is important because sometimes there is still an identifiable train of thought that can be restored, and the relation of parallel accounts, their sources, and the choices of individual source authors can be spelled out more precisely.
