Apophatic theology—also known as Negative theology or Via Negativa (Latin for "Negative Way")—is a theology that attempts to describe God, the Divine Good, by negation, to speak only in terms of what may not be said about the perfect goodness that is God. It stands in contrast with Cataphatic theology.
In negative theology, it is accepted that the Divine is ineffable, an abstract experience that can only be recognized or remembered—that is, human beings cannot describe in words the essence of the perfect good that is unique to the individual, nor can they define the Divine, in its immense complexity, related to the entire field of reality, and therefore all descriptions if attempted will be ultimately false and conceptualization should be avoided; in effect, it eludes definition by definition:
