“God is dead and we have killed him” was the cry of Nietzsche as the western world absorbed the new rational ideas of the enlightenment. But this was a cry of despair. As civilization became increasingly rational, the attitude towards religion changed. People are more secular as a consequence of widespread rationalism. In addition, even those that remain religious have de-mystified their worship and practices.
But we as humans face the burden of existence. Having a transcendent framework is useful to grapple with this. The fact that life goes on and on until we die and the world keeps turning despite our actions is scary. When humans look up to something greater than themselves, it helps them cope. But as Nietzsche announced, God is dead. Society has left behind what it used to look up to. In turn, we have begun to worship a different god. This new false idol is the politician.
