Few other theories in physics come close to the stunning beauty, and revolutionary nature, as Einstein's.  We can no longer describe physical phenomenon in absolute terms and call ourselves accurate; instead everything must be described in terms of relativity.

But the idea of relativity didn't stay in the cosmos.  It came to Earth.  Modern man has brought Einstein's theory of general relativity from the realm of physics into metaphysics, from science into philosophy.  The zeitgeist, or spirit of the times, can be summarized in the term "moral relativism."
