This is not to say that every opinion about the universe deserves equal attention, as if schoolteachers should be enjoined to give equal weight to the flat-Earth theory, ESP. or the existence of extraterrestrials. That no one theory of the universe can deservedly gain permanent predominance does not mean that all theories are equally valid. In fact, to understand the limitations of science (and art and philosophy) can be a source of strength, emboldening us to renew our search for the objectively real even though we understand that the search will never end. I often reflect on a remark made to me one evening over dinner by a famous scientist: "The world is a fantasy, so let's find out about it." To me, that heroic statement encapsulates the spirit of science: to seek to learn something while accepting that one will never know everything.
