Meaning and Definition
The cosmological principle that observations of the universe must be compatible with the conscious and sapient life that observes it.
A philosophical or scientific consideration that the universe's fundamental constants and laws appear finely tuned to allow for the existence of life, particularly intelligent observers. It comes in 'weak' (the universe must allow observers at some point) and 'strong' (the universe must allow observers from its beginning) forms.
