If asked whether or not our world-view is “true” we can say, “Yes, in a sense, but only against my theoretical or metaphysical background.” If asked whether or not creationism is “true” we can say “No, in a sense, against my theoretical or metaphysical background.”

Or just be a pragmatist and say that there is no objective truth.

Or just be a pragmatist and say that there is no objective truth.

It's one thing to recognize the limits of discerning truth under one set of metaphysical assumptions, but entirely another to deny that one set of metaphysical assumptions might ultimately be correct.
