Abstract

Considering the fair amount of ancient authors who compiled works on the subject of the ‘History of Philosophy’, it is remarkable—and regrettable—that there is no solid basis for a comparative analysis of their structures. Most ancient histories of philosophy are only preserved in a few fragments or excerpts and hardly allow any meaningful non-trivial comparison of the structure and order of the philosophers and schools discussed. The only more or less entirely preserved ‘History of Philosophy’ is Diogenes Laertius’ famous treatise. Although his work seems to offer an idiosyncratic rendering in some respects, and is hardly representative of the genre, some structural similarities with Sotion's Διαδοχαί (Successions) can be identified. Generally, a crucial question concerning the structure is how the philosophers and their schools were arranged in these works. Did the works basically follow a chronological order? How were the Διαδοχαί arranged? Were certain schools or philosophers dealt with together in a single book or in more than one book, or were they presented in a certain order?
