Relativism - Criticisms

Criticisms

A common argument against relativism suggests that it inherently contradicts, refutes, or stultifies itself: the statement "all is relative" classes either as a relative statement or as an absolute one. If it is relative, then this statement does not rule out absolutes. If the statement is absolute, on the other hand, then it provides an example of an absolute statement, proving that not all truths are relative. However, this argument against relativism only applies to relativism that positions truth as relative–i.e. epistemological/truth-value relativism. More specifically, it is only strong forms of epistemological relativism that can come in for this criticism as there are many epistemological relativists who posit that some aspects of what is regarded as "true" are not universal, yet still accept that other universal truths exist (e.g. gas laws). However, such exceptions need to be carefully justified, or "anything goes".

Another argument against relativism posits a Natural Law. Simply put, the physical universe works under basic principles: the "Laws of Nature". Some contend that a natural Moral Law may also exist, for example as argued by Richard Dawkins in The God Delusion (2006) and addressed by C. S. Lewis in "Mere Christianity" (1952). Dawkins said "I think we face an equal but much more sinister challenge from the left, in the shape of cultural relativism - the view that scientific truth is only one kind of truth and it is not to be especially privileged."

The philosopher Plato opposed relativism. He criticized the views of the sophist Protagoras in his dialogue Thaetetus. In a paraphrased dialogue, the philosopher Socrates argued that relativism is self-defeating with the following: "My opinion is: Truth must be absolute and that you Mr. Protagoras, are absolutely in error. Since this is indeed my opinion, then you must concede that it is true according to your philosophy."

An argument made by philosopher Hilary Putnam, among others, states that some forms of relativism make it impossible to believe one is in error. If there is no truth beyond an individual's belief that something is true, then an individual cannot hold their own beliefs to be false or mistaken. A related criticism is that relativizing truth to individuals destroys the distinction between truth and belief.
