Apophatic theology (from Greek ἀπόφασις from ἀπόφημι - apophēmi, "to deny")—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 brief, negative theology is an attempt to achieve unity with the Divine Good through discernment, gaining knowledge of what God is not (apophasis), rather than by describing what God is. The apophatic tradition is often, though not always, allied with the approach of mysticism, which focuses on a spontaneous or cultivated individual experience of the divine reality beyond the realm of ordinary perception, an experience often unmediated by the structures of traditional organized religion or the conditioned role-playing and learned defensive behavior of the outer man.

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:
