Article link: Relativism Self-Destructs
The demon of our age, relativism, was addressed by a letter writer in today's edition of the Daily Nation.

Another good resource is the May/June 2005 issue of Solid Ground, which contains A Premier on Moral Relativism. You *might* have to register as an ambassador on Stand to Reason to access the link though.
