The unsatisfactory status of the interpretation of the wave function of the Universe in canonical quantum gravity is reviewed. The "naive interpretation" obtained by straightforwardly applying the standard interpretive rules to the canonical quantization of general relativity is manifestly unacceptable; the "WKB interpretation" has only a limited domain of applicability; and the "conditional probability interpretation" requires one to pick out a "preferred time variable" {or preferred class of… Expand
