The logical position against any claim of relativism to absoluteness is that "absolute relativism" is a self-contradictory term, an impossible combination of words. If one avoids this impossible combination of words, relativism itself becomes relative; therefore an element of absoluteness is not only a possibility but even a necessity, otherwise no assertion at all can be made.
But absolute relativism is also impossible practically. If I am asked to surrender totally to relativism I can say "But I live! I know what 'true' and 'false' mean, I do something I can describe as 'better' than something else, I venerate something which concerns me ultimately and which for me is holy." The question then is: How can one make such statements if relativism has the last word? In the different reality of man's encounter with reality there must be some absolutes that make meaningful life possible, of it would be like the chaos before creation, described in Genesis. Therefore I believe it may be a service to life itself to find these absolutes and to show their validity and their limits.
