Anthropics versus Determinism in Quantum Gravity

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.
