The greater good
Only answer the questions that apply to your position!
We say that christians are irrational. Yet there have been many christians who changed societies for the better - MLK jr, Nelson Mandella, and Frederick Douglas. Is it possible to be irrational and change society for the better? Is this a contradiction?
Atheists are often said to have no "faith." That they don't believe in a greater purpose in life than their own material beliefs. Yet, one of the greatest revolutionaries of all time was an atheist, Karl Marx. Do you think it is possible for someone to change society for the good without believing in God? If so, where do they get their morality from?
