Chief Justice Renquist and legal positivism
Chief Justice Renquist certainly has a reputation as one of the most conservative members of the court. However, he has continually expounded a doctrine of legal positivism. Logical positivism was a linguistic movement in the early 20th century. It proposed that there were two types of statements. Essentially there were factual statements, and matters of simple opinion, unrelated to fact. Moral statements were in the latter class.

Renquist has expressed the idea that there is no right or wrong within the law, there is only majority opinion, and therefore he believes in almost always deferring to the will of the legislature, that represents the will of the majority.

The will of the majority of course, will often reflect the traditions they are accustom to. 
So, here we have a concrete example of the intimate relationship between traditionalism and relativism.
