Religion is a system of human norms and values that is founded on belief in a superhuman order. The theory of relativity is not a religion, because (at least so far) there are no human norms and values that are founded on it. Football is not a religion because nobody argues that its rules reflect superhuman edicts. Islam, Buddhism and Communism are all religions, because all are systems of human norms and values that are founded on belief in a superhuman order.

If I believe in God at all, it is my choice to believe. If my inner self tells me to believe in God- then I believe. I believe because I fell God's presence, and my heart tells me He is there. But if I no longer feel God's presence, and if my heart suddenly tells me that there is no God-I will cease believing. Either way, the real source of authority is my own feelings. So even while saying that I believe in God, the truth is that I have a much stronger belief in my own inner voice.

Humanism split into three main branches. The orthodox branch holds that each human being is a unique individual possessing a distinctive inner voice and a never-to-be-repeated string of experiences. Every human being is a singular ray of light, which illuminates the world from a different perspective, and which adds colour, depth and meaning to the universe.

During the nineteenth and twentieth centuries, as humanism gained increasing social credibility and political power, it sprouted two very different offshoots: socialist humanism, which encompassed a plethora of socialist and communist movements, and evolutionary humanism, whose most famous advocates were the Nazis. Both offshoots agreed with liberalism that human experience is the ultimate source of meaning and authority.
