dualistic, and some Gnostic traditions posited that the Devil was separate from God as an independent deity. The Christian dualists of the Byzantine Empire, the Paulicians, were seen as Manichean heretics by Byzantine theologians. This tradition of Christian dualism, founded by Constantine-Silvanus, argued that the universe was created through evil and separate from a moral God. Cathars The Cathars, a Christian sect in southern France, believed that there was a dualism between two gods, one representing good and the other representing evil. Whether or not the Cathari possessed direct historical influence from ancient Gnosticism is a matter of dispute, as the basic conceptions of Gnostic cosmology are to be found in Cathar beliefs (most distinctly in their notion of a lesser creator god), though unlike the second century Gnostics, they did not apparently place any special relevance upon knowledge (gnosis) as an effective salvific force. In any case, the Roman Catholic Church denounced the Cathars as heretics, and sought to crush the movement in the 13th century. The Albigensian Crusade was initiated by Pope Innocent III in 1208 to remove the Cathars from Languedoc in France, where they were known as Albigensians. The Inquisition, which began in 1233 under Pope Gregory IX, also targeted the Cathars. In Hinduism The Dvaita Vedanta school of Indian philosophy espouses a dualism between God and the universe by theorizing the existence of two separate realities. The first and the more important reality is that of Shiva or Shakti or Vishnu or Brahman. Shiva or Shakti or Vishnu is the supreme Self, God, the absolute truth of the universe, the independent reality. The second reality is that of dependent but equally real universe that exists with its own separate essence. Everything that is composed of the second reality, such as individual soul (Jiva), matter, etc. exist with their own separate reality. The distinguishing factor of this philosophy as opposed to Advaita Vedanta (monistic conclusion of Vedas) is that God takes on a personal role and is seen as a real eternal entity that governs and controls the universe. Because the existence of individuals is grounded in the divine, they are depicted as reflections, images or even shadows of the divine, but never in any way identical with the divine. Salvation therefore is described as the realization that all finite reality is essentially dependent on the Supreme. Ontological dualism Alternatively, dualism can mean the tendency of
