neutrosophy \neutrosophy\, n. [L. neuter neutral, Greek sofia
   skill, wisdom.] (Philosophy)
   A branch of philosophy, introduced by Florentin Smarandache
   in 1980, which studies the origin, nature, and scope of
   neutralities, as well as their interactions with different
   ideational spectra. Neutrosophy considers a proposition,
   theory, event, concept, or entity, "A" in relation to its
   opposite, "Anti-A" and that which is not A, "Non-A", and that
   which is neither "A" nor "Anti-A", denoted by "Neut-A".
   Neutrosophy is the basis of neutrosophic logic, neutrosophic
   probability, neutrosophic set, and neutrosophic statistics.
