I'm writing a somewhat journalistic series of pieces, in which I nonetheless am trying to provide firm scholarly footing for accounts of various controversies that have taken place in Buddhism, both in classical and modern times. The piece that I am working on now involves the characterization of the "Yogachara Buddhism" as "idealism." Meaning "idealism" as a position that takes all of reality to reside within the mind, and not in the external world.
It seems that there was apparently a debate on this topic between the scholars Kapstein and Hopkins in the 1980's, centered on works from the Tibetan tradition. In any case, I'd be interested in knowing other circumstances and traditions in which the debate took place, and if this issue still has currency in modern scholarship?
Much obliged for any information.
