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

I think that as well as the arguments that can be made for relativism in terms of there being relative truths from person to person at one time, there are even more simple arguments when you think about time. To say that Stephen Harper is the Prime Minister of Canada is true for anyone right now, to say the same thing a hundred years ago, this obviously would not have been true for anyone. It seems there are lots of transitory truths that are relative to groups of people as well as just individuals.
