Thank you for that link...I hope that everyone on this forum will read and understand where Asimov is coming from, even if they do not completely agree with him. I have lived and am living the progression of morality through experience. I was raised without direct religious indoctrination. I, of course, knew about Christianity early on (and other religions later) through books and then through friends (I was a voracious reader well before the age when my friends started talking about God) and my parents (mom raised Methodist, dad raised Catholic) told me that I could go to Sunday school with some of my friends but they told me that I could not attend any church regularly until I was 13 so that I would be able to ask critical questions while I made my spiritual journey. I was able to explore many religious doctrines and philosophies without the bias of one was right and the others wrong.
My sense of morality was based on stories told by my parents about war, their own lives, sharing with my siblings and lessons learned about pain and kindness and everything that I experienced as a child. That is the same as certain religions, I suppose, because I learned from stories passed down to me and applied them to my life. I am still developing my "morals" every day based on what I have learned and what I can apply to my basic tenet: (like the Wiccans and others) to harm none.
Christians believe they have a monopoly on morality, but I feel that as long as you believe that you can be forgiven of anything, you are capable of doing anything.
