Details: I shall discuss consequences of envariance (environment - assistedinvariance; symmetry exhibited by entangled quantum states). I shall focuson the implications of envariance for the understanding of the originsand nature of ignorance, and, hence, for the origin of probabilitiesin physics. While the derivation of the Born's rule for probabilities is the principal accomplishment of this research, I shall explore the possibility that several other symptoms of the quantum- classical transition that are a consequence of decoherence can bejustified directly by envariance -- i.e., without invoking Born's rule.
