The following brief exchange in the Pope’s conversation with Eugenio Scalfari has generated some interest and indeed some perplexity. It is as follows: 

Your Holiness, is there is a single vision of the Good? And who decides what it is?

"Each of us has a vision of good and of evil. We have to encourage people to move towards what they think is Good."

Your Holiness, you wrote that in your letter to me. The conscience is autonomous, you said, and everyone must obey his conscience. I think that's one of the most courageous steps taken by a Pope.
