Symbolic (or Literal) Neutrosophic Theory is referring to the use of abstract symbols (i.e. the letters T, I, F, representing the neutrosophic components truth, indeterminacy, and respectively falsehood, or their refined components, represented by the indexed letters Tj, Ik, Fl) in neutrosophics. This book treats the neutrosophy, neutrosophic logic, neutrosophic set, and partially neutrosophic probability.

In the first chapter, we extend the dialectical triad thesis-antithesis-synthesis (dynamics of and , to get a synthesis) to the neutrosophic tetrad thesis-antithesis-neutrothesisneutrosynthesis (dynamics of , , and , in order to get a neutrosynthesis). We do this for better reflecting our world, since the neutralities between opposites play an important role. The neutrosophic synthesis (neutrosynthesis) is more refined that the dialectical synthesis. It carries on the unification and synthesis regarding the opposites and their neutrals too.
