The German philosopher Immanuel Kant once wrote that he “had to deny knowledge to make room for faith.” The French physicist Bernard d’Espagnat hasn’t denied knowledge in his long career developing the philosophy that won him this year’s $1.42 million Templeton Prize. He was pursuing knowledge to better understand what we can know about the ultimate reality of the world. But just like his philosophy echoes that of Kant’s with its conviction that there are limits on knowing reality, his work leaves some room — he would say for spirituality — by saying that human intuitions like art, music and spirituality can help us go further when science searching to understand the world reaches the end of its tether.
