Idealism thus rejects physicalist and dualist theories that fail to ascribe priority to the mind. Both a monist state and a dualist state can comply with international law. Harry Oldmeadow notes that Jain ontology is both realist and dualist metaphysics. He also cited in the epistles a synthesis with the opposing dualist forces of Gnosticism. The metaphysics of Patanjali is built on the same dualist foundation as the Samkhya school. The metaphysics of Yoga is built on the same dualist foundation as the Samkhya school. Founded by Madhva, the Dvaita (dualist) rejects the Advaita (non-dualist) notion of one ultimate reality. The Yoga philosophical system aligns closely with the dualist premises of the Samkhya school. It is therefore a strongly dualist philosophy. One of the earliest Christian dualist sects, Marcionism, originated in eastern Anatolia. Hohenwart advocated federalism and collapse of the dualist policy. This is salvation to dualist schools of Hinduism. Dualist theories are documented from the 16th century onwards. It was the first sign that dualist policy would collapse in favour of federalism. On that understanding, Nagel is a conventional dualist about the physical and the mental.
