Neutrosophy means: Common Parts to Uncommon Things and Uncommon Parts to Common Things.

Let <A> be an item, concept, idea, proposition, school of thought, current, theory, etc. and <antiA> be the opposite of <A>. Analogously for and its opposite <antiB>. Neutrosophy means to find: (i) common parts to uncommon things (that is, <A> and <antiA> have something in common, or their intersection <A>n<antiA> is not empty), and vice versa: (ii) (ii) uncommon parts to common things (the two equal items <A>= have also uncommon parts, either <A>n<antiB> is not empty, or <antiA>n is not empty). Both, the Common Parts to Uncommon Things, and the Uncommon Parts to Common Things, end up being parts of indeterminacy / neutrality situated between the opposites: denoted by <neutA>, which means neither <A> nor <antiA>, but in between them; and respectively by <neutB>, which similarly means neither nor <antiB>, but in between them.
