His Highness the Aga Khan delivers the LaFontaine-Baldwin Lecture in Toronto, Canada. His Highness talked about the long history of pluralism, the intensification of these challenges and how best to respond to that challenge. "The world we seek is not a world where difference is erased, but where difference can be a powerful force for good, helping us to fashion a new sense of cooperation and coherence in our world, and to build together a better life for all," said the Aga Khan.
