But are there not truths beyond mere opinion?
Do not mathematics and physics show many examples of Truth which is not dependent on perspective or interpretation; is not 2+2 always 4, regardless of one's opinion on the matter?
And if there are absolutes we know exist in reality, could there not be absolutes which we do not know to be absolute, not because of their intrinsic relativity but more because we in our limited perspective cannot appreciate their eternal constance?
