Biblical Christianity 101, a study of the book of Romans

[John V]

My position is called the Tit-For-Tat Rule. In short, it means "be altruistic to others until you see they are not playing by the rules, then treat them as they treat you". You can read about it, here.

Interesting read, particularly:

The most admired standard of behavior, in the West, at least, is the Golden Rule, attributed to Jesus of Nazareth. Everyone knows its formulation in the first-century Gospel of St. Matthew: Do unto others as you would have them do unto you. Almost no one follows it.

So, Sagan agrees that people don't live up to Biblical standards.
