Dualism (Indian philosophy)
Dualism in Indian philosophy refers to the belief held by certain schools of Indian philosophy that reality is fundamentally composed of two parts. This mainly takes the form of either mind-matter dualism in Buddhist philosophy or consciousness-matter dualism in the Samkhya and Yoga schools of Hindu philosophy. These can be contrasted with mind-body dualism in Western philosophy of mind, but also have similarities with it.
Mind–body dualism
The central claim of what is often called "Cartesian dualism", in honor of Descartes, is that the immaterial mind and the material body, while being ontologically distinct substances, causally interact. This is an idea that continues to feature prominently in many non-European philosophies. Mental events cause physical events, and vice versa. But this leads to a substantial problem for Cartesian dualism: How can an immaterial mind cause anything in a material body, and vice versa? This has often been called the "problem of interactionism."
