Defining or describing by negation. Typically used to refer to knowledge about God framed by what God is not. Contrasts with cataphatic [theology].
In Buddhism
Buddhist philosophy has also strongly advocated the way of negation, beginning with the Buddha’s own theory of anatta (not-atman, not-self) which denies any truly existent and unchanging essence of a person. Madhyamaka is a Buddhist philosophical school founded by Nagarjuna (2nd-3rd century AD), which is based on a fourfold negation of all assertions and concepts and promotes the theory of emptiness (shunyata). Apophatic assertions are also an important feature of Mahayana sutras, especially the prajñaparamita genre. These currents of negative theology are visible in all forms of Buddhism. 1
