- The Weak Anthropic Principle
goes halfway toward an answer by applying a probabilistic selection function: “the relationship
has been logically selected by the fact that only certain kinds of universe can accommodate acts
of observation and an observer like the questioner.” This is right as far as it goes, but omits the
generative, pre-selective phase of the explanation … the part that accounts for the selection
function and the domain to which it is applied. In this respect, the WAP is a bit like natural
selection; it weeds the garden well enough, but is helpless to grow a single flower.
