Mind in eastern philosophy
The study of the mind in Eastern philosophy has parallels to the Western study of the Philosophy of mind as a branch of philosophy that studies the nature of the mind. Dualism and monism are the two central schools of thought on the mind–body problem in the Western tradition, although nuanced views have arisen that do not fit one or the other category neatly. Dualism is found in both Eastern and Western traditions (in the Sankhya and Yoga schools of Hindu philosophy as well as Plato) but its entry into Western philosophy was thanks to René Descartes in the 17th century. This article on mind in eastern philosophy deals with this subject from the standpoint of eastern philosophy which is historically strongly separated from the Western tradition and its approach to the Western philosophy of mind.
Non-physical entity
Dualism is the division of two contrasted or opposed aspects.The dualist school supposes the existence of non-physical entities, the most widely discussed one being the mind. But beyond that it runs into stumbling blocks. Pierre Gassendi put one such problem directly to René Descartes in 1641, in response to Descartes's "Meditations":
Descartes' response to Gassendi, and to Princess Elizabeth who asked him similar questions in 1643, is generally considered nowadays to be lacking, because it did not address what is known in the philosophy of mind as the interaction problem. This is a problem for non-physical entities as posited by dualism: by what mechanism, exactly, do they interact with physical entities, and how can they do so? Interaction with physical systems requires physical properties which a non-physical entity does not possess.
