The Anthropic Principle, in use by physicists, astronomers, and cosmologists, is currently under consideration by philosophers. This principle, in its various forms, appeals to man's existence as a constraint on our determination of natural laws and natural constants, as a principle of prediction, and, in its strongest form, as a principle of explanation which sanctions an argument for the universe being a product of design. What I shall endeavour to show here is (1) how this principle, in its various forms, is used in furthering our understanding of cosmology, and (2) why this principle cannot be used as a principle of explanation.
