Relativism’s Worldview of Authority:

The human mind is the only authority, the imagination of each person.  The Post Modern scholars and theologians are often held up as authorities.  The bottom line is that nothing and no one has any real authority, because, in the mind of the relativist, there is no truth.  

For the relativist, all of the above are true at once even though they are conflicting ideas.  You may say that this is insane, and it is.
