There is increasing evidence that the universe may have a small cosmological
constant. We suggest a scheme for naturally generating a small cosmological
constant. Our idea requires the presence of a discrete accidental symmetry
which is spontaneously broken by vacuum expectation values of the fields, and
explicitly broken by high dimensional operators in the Lagrangian.
