Quote from : Good and Evil: Two Sides of the Same Coin Book

Every faith has logic even though people after developing faith forget the logic behind the faith. There is a strong logic behind the creation of religion—the greatest symbol of human faith—that has provided a common code of conduct and belief, and brought millions or even billions of people together. Religion has benefited man even materialistically, as it reduced the conflict between individuals and ushered in a long era of peace and prosperity.
