The strong anthropic principle is a variation on the anthropic principle which states that the whole of existence is tailored to the presence of intelligent life. It differs from the weak anthropic principle in its assertion that the entire universe/multiverse is set up for the support of life, instead of merely requiring that the directly perceivabe area that life exists in be conducive to said existence.

As with the term weak anthropic principle, the strong anthropic principle was originally coined by Brandon Carter in the 1970s. His work led into further extensions of anthropic thought, and is largely responsible for current rhetoric used by Creationists and others who wish to prove intelligent design. This usage is, at best, an extension of his thought, and, at worst, a corruption of the original meaning, since Carter made no mention of deity or such concepts in his material.
