He's also a devout Catholic and a spiritual thinker; he and his wife raised their family in intentional communities centered around people with mental disabilities. In recent years, he's pursued his interests in religion, the history of ideas, and the life sciences together with his knowledge of frailty and flaws as essential elements in living geological systems. Xavier Le Pichon has come to think of caring attention to weakness as an essential quality that allowed humanity to evolve. [Broadcast Date: August 16, 2012]
