  Recently the multitude of vacua in string theory have led some authors to
advocate the anthropic principle as a possible resolution for the contrived set
of parameters that seem to govern our universe. I suggest that string theories
should be viewed as effective theories, and hence of limited utility rather
than as ``theories of everything''. I propose that quantum gravity should admit
a form of determinism and that the self-dual points under phase-space duality
should play a prominent role in the vacuum selection principle.
