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.
Mutualism (economic theory)
Dual power should not be confused with the Dual Power popularized by Vladimir Lenin, which was also theorized by Proudhon, but is referring to a more specific scenario where a revolutionary entity intentionally maintains the structure of the previous political institutions until the power of the previous institution is weakened enough such that the revolutionary entity can overtake it entirely. Dual-power as implemented by Mutualists and Agorists is the development of the alternative institution itself, which can create the Leninist scenario.
