Plato taught about a realm of ideas vs. a material realm, and the realm of ideas subsequently working as a basis for our ethics.
Is this called "Gnosticism" or does Gnosticism build on Platonic thought? What is the platonian teaching called if not gnosticism? Also, do you have any references about links between buddhism and platonic thought?
Thank you/ Tony
Gnosticism was certainly influenced by Platonic philosophy, but the two are not the same thing. Rather than going into details here, I suggest that you go to the Internet Encyclopedia of Philosophy (advertised on the lower right of this page--just click on it) and look up "Gnosticism." There is a philosopher named May Sim at College of the Holy Cross who has done some work on comparisons between Asian philosophies and ancient Greek philosophy. You might try contacting her to find out more about that topic.
