Mind–body dualism
Ontological dualism makes dual commitments about the nature of existence as it relates to mind and matter, and can be divided into three different types:Substance dualism is a type of dualism most famously defended by René Descartes, which states that there are two kinds of foundation: mental and body. This philosophy states that the mental can exist outside of the body, and the body cannot think. Substance dualism is important historically for having given rise to much thought regarding the famous mind–body problem. Substance dualism is a philosophical position compatible with most theologies which claim that immortal souls occupy an independent realm of existence distinct from that of the physical world.
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."
