Voluntarism \Vol"un*ta*rism\, n.
   Any theory which conceives will to be the dominant factor in
   experience or in the constitution of the world; -- contrasted
   with {intellectualism}. Schopenhauer and Fichte are typical
   exponents of the two types of metaphysical voluntarism,
   Schopenhauer teaching that the evolution of the universe is
   the activity of a blind and irrational will, Fichte holding
   that the intelligent activity of the ego is the fundamental
   fact of reality.
