Philosophy of mind
Dualism is a set of views about the relationship between mind and matter (or body). It begins with the claim that mental phenomena are, in some respects, non-physical. One of the earliest known formulations of mind–body dualism was expressed in the eastern Sankhya and Yoga schools of Hindu philosophy (c. 650 BCE), which divided the world into purusha (mind/spirit) and prakriti (material substance). Specifically, the Yoga Sutra of Patanjali presents an analytical approach to the nature of the mind.
Yanantin
Yanantin is one of the best known and most defining characteristics of indigenous South American Andean thought and exemplifies Andean adherence to a philosophical model based in what is often referred to as a "dualism of complementary terms" or, simply, a “complementary dualism". Much like in Chinese Taoism, Andean philosophy views the opposites of existence (such as male/female, dark/light, inner/outer) as interdependent and essential parts of a harmonious whole. Because existence itself is believed to be dependent upon the tension and balanced interchange between the polarities, there is a very definite ideological and practical commitment within indigenous Andean life to bringing the seemingly conflicting opposites into harmony with one another without destroying or altering either one. Among the indigenous people of Peru and Bolivia, the union of opposing yet interdependent energies is called "yanantin" or "complementary opposites."
