The Mind-Body problem in Western philosophy concerns the difficulty in conceiving the nature of interaction between mind and body, considering that these two are supposed to be different substances—one physical and material while the other spiritual or mystical. In Indian philosophy, matter itself transforms into spirit and how this transformation occurs poses a serious problem.
Descartes created the mind-body divide and claimed these to be two different substances—the extended substance (res extensa) and the thinking substance (res cogitans). However, with the progress in science (and attempts to subsume thinking under matter), the distinction between mind and body gets hazier by the day. What is the difference between matter and spirit, if any at all?
