Legion: Just posting a comment and question, do you believe in a dualistic worldview? If so, then such a belief system professes that life has absolutes: absolute good and absolute evil. Unless a person lives a sheltered life, then obviously one would conclude that a dualistic worldview does not fit into reality as life is very complicated. In reality, the world is very diverse and does not fit into nice little boxes (metaphorically speaking).
Cultural norms and mores refer to indivudual concepts of "good and evil."
For example, orthodox Muslims believe eating pork is evil. Some or most Jews believe in kosher meals as it is believed wrong for certain foods to be next to one another. Hindus believe cows are holy & thus eating one would be a great sin.
The point is: the world doesn't exist is simple black/white absolutes. Life is much more complicated & diverse.
