Intolerance \In*tol"er*ance\, n. [L. intolerantia impatience,
   unendurableness: cf. F. intol['e]rance.]
   1. Want of capacity to endure; as, intolerance of light.

   2. The quality of being intolerant; refusal to allow to
      others the enjoyment of their opinions, chosen modes of
      worship, and the like; want of patience and forbearance;
      illiberality; bigotry; as, intolerance shown toward a
      religious sect.

            These few restrictions, I hope, are no great
            stretches of intolerance, no very violent exertions
            of despotism.                         --Burke.
