This is a video of a lecture by Rabbi Sacks called "The Dignity of Difference" delivered at Duke University in 2007. The lecture is about 40 minutes long and starts a bit slow (Rabbi Sacks begins it @ 12 min marker). But if you enjoy deeper and broader thinking you are in for a treat. The lecture challenges us to re-read the familiar narratives of Isaac and Ishmael, Jacob and Esau and see a story often missed. Rabbi Sacks is one of the best speakers I have witnessed on stage. Besides that, he is an incredibly talented writer and preacher, so I recommend his books often. It's a rare combination of talents.
His book (with the same title) as this 2007 lecture addresses the contemporary cultural and religious struggles. Very relevant even today! Rabbi Sacks affirms the inherent dignity and worth of every individual, irrespective of race, religion, culture and warns against the perils of homogenizing cultures and imposing a dominant way of thinking on others.
