I have learned so much more about Islam in conversation with Jews and Christians and Hindus. I feel like that is part of the beauty of life on Earth - that we discover and develop what it means to be Muslim or Christian or Jewish not in isolation from others, but precisely in relationship with others.

I thought about the meaning of pluralism in a world where the forces that seek to divide us are strong. I came to one conclusion: We have to save each other. It’s the only way to save ourselves.

The totalitarians in the world are very, very small. Only the smallest part of humanity wishes and acts upon the destruction of others. The pluralists are far larger. Those of us who believe in a world where we live together - we're far larger. The problem is we haven't made our case compelling across the world yet.

Religious extremists want to show us that the only possibility is for us to kill each other, so September 11 is not only heinous murder, it is also global performance. It is also putting an idea into the world, an idea of destruction.

To teach your child to only be a Muslim in Muslim spaces or only a Christian in Christian spaces means in a way that you're teaching them a religious identity that is relevant to only a very small part of their lives, because the vast majority of their lives in the 21st century are going to be lived in interaction with others.

A social entrepreneur is somebody who knows how to make an idea reality, and one of the great ideas of our time is pluralism. Can people from different backgrounds live together in mutual peace and loyalty? And what we need is a generation of young social entrepreneurs who know how to make that great idea reality in an historical moment where religious extremists are, frankly, making their idea reality.

When thousands of people discover that their story is also someone else's story, they have the chance to write a new story together.
