anthropic principle(an-throp -ik) A principle that was put forward in the 1960s by R. Dicke and maintains that the presence of life in the Universe places constraints on the ways in which the very early Universe evolved: the possible initial conditions are limited to those that give rise to an inhabited Universe, i.e. what we observe must be restricted by the conditions necessary for our presence as observers.
