Abstract
Spontaneous breaking of parity or time reversal invariance offers a solution to the strong CP problem, the stability of which under quantum gravitational effects provides an upper limit on the scale of symmetry breaking. Even more important, these Planck scale effects may provide a simple and natural way out of the resulting domain wall problem. (Invited talk at the 4th Hellenic School on Elementary Particle Physics, Corfu, Greece, September 1992.
