A promising, inclusive approach to ancient philosophy is on display in the Oxford Network for Ancient Philosophy, which describes itself as follows:
The Oxford Network for Ancient Philosophy (ONAP) brings together faculty and students specializing in ancient philosophy across the University of Oxford. Oxford is an extraordinarily rich environment for the study of ancient philosophy, with leading researchers working on ancient Chinese, Greek, Indian, Roman philosophy, and more across a range of Humanities faculties. This forum seeks to support the vibrant community of staff and students working in all areas of ancient philosophy by providing up-to-date, cross-departmental resources and information geared to the study and teaching of ancient philosophy within Oxford.
The ONAP homepage is here. If you are familiar with other, similarly inclusive/boundary-crossing approaches to ancient philosophy, please share in the comments! (I know they’re out there….)
