Perhaps the answer lies in our human desire to try and understand to make sense of the world. In science or mathematics, there is often one right answer.

In man's understanding of the world and of each other, that does not happen. So we strive, we seek and we hope to find peace. To come to terms with some answer that explains it all. But life, physical and spiritual and even social and political is not like physics. There is no one answer

This is where I begin my conversation with Pico Iyer.
