Ancient Philosophical Texts

Here I offer the foundation for a comprhensive list of ancient philosophical texts available online. Some of these links repeat those elsewhere in this site, but it seemed useful to include this list as well. I also include a number of important doxographical works by Church Fathers. All of the texts listed here are in English. For Greek texts visit the Perseus Project; for Latin texts visit The Latin Library. A selection of texts is also available from this site.
