Comparative Religion

Julia Hanna and Aya Katz discuss differing attitudes and views about religion. Is the question of whether a person can be described as religious based on belief in the existence of a deity? Or can we worship and revere even when we do not believe in the physical existence of a god or gods? Is religion more about values than facts?

Q: If someone prays out loud to God, can that person be deemed not religious? Can you pray to a god you do not believe in? How do you see this behavior? Is religion a personal matter or is it about social affiliation? Is religion antagonistic to science or merely a complement to science? If there should be a separation of church and state, should there also be a separation of science and state? Of education and state? Of commerce and State? Of life and state?
