Differenza epistemologica e identità ontologica tra Sa？sāra e Nirvā？a nel pensiero buddhista

the difference between the concepts of sa？sāra e nirvā？aset forth by the historical buddha (vi-v b.c.) in his first sermon seem to be disputed by the equalization of the two terms effected by nāgārjuna (ii a.d) in a topical passage of his mk. this article, firstly, supports the thesis that the contradiction is just a seeming one and that the relation of difference or identity between the two dimensions depends on the philosophical register, respectively epistemological and ontological, being used - in both cases for soteriological purposes - by the buddha and nāgārjuna. secondly, we wish to prove that, in any case, nāgārjuna's ontology, far from being a philosophical novelty or an evolution of the thought of the founder of buddhism, is, on the contrary, one of the possible applications of the "non-self" doctrine (anātma-vāda) - probably the most important and original contribution of buddhist thought to the history of world philosophy - expounded by the buddha in his second sermon.
