Thangka showing buddist world view and Nagarjuna, 2nd century C.E. (I believe) or 2nd century BC was "the second Buddha" that had been prophesied.

He is considered a pre-eminent logician and epistemologist. His final position is that no positions are possible. He is the (as far as I know) view of the Two Truths, remarkably close to current scientific world view: i.e., ultimately there is the background luminosity (yes, that is the word they use), atoms and the void, that sort of thing and this ultimate reality is not describably in words (c.f. Feynmann if you think you understand quantum mechanics you don't).

Ultimately nothing can be asserted BUT RELATIVELY or like say, Wittgenstein or Charles Sanders Pierce would say, conventionally then you have the world we experience. Of course, as the Buddha observed there is nothing to depend on -- all world views are relative. Anyway, conventionally, relatively, beings exist and they suffer so a being that understands both the ultimate view and the conventional view will, while being free of hope and fear him(herself) will have Great Compassion for beings who experience this relative reality as ultimate and All Too Real. They need to be enlightened, then they can experience equanamity and not be trapped in cycle of samsara etc.

Nagarjuna is the one who said samsara and nirvana are the same.

He also said, along with the Buddha everything we experience is relative, with the exception of the glimpse or taste of ultimate reality one can gain in meditation and then experience more and more in their daily experience

He said the one who thinks there is some ultimate view of the world that holds that relative things are empty of inherent existence has accomplished nothing, in otherwords he admonished us about the emptiness of emptiness. Which is an admonition most modern day scientists, those that are not naive materialists should heed.

Blah blah blah. From Alan Wallace who wrote the Quantum Mechanics and Buddhism book says that Wittgenstein's view is Nagarjuna's view (although Nagarjuna beat Wittgenstein by almost a millennium). Buddhism is dialectical, in that many opinions are held, Buddha like Wittgenstein thought philosophy's role was to cure, to show the "fly the way out of the fly bottle" but ultimately nothing can be asserted.
