forum for week of 21 Nov: the appeal of truth relativism

I believe that there are fundamental truths. We make use of whatever "true" beliefs we have, and whenever more rational beliefs come along, we abandon our "true" beliefs and make use of the new ones. In this way, we constantly strive for the underlying truths. When someone believes something to be "true", it is purely arbitrary, it is only true to them. Knowledge is not arbitrary, it requires fundamental truths.
