Xavier Le Pichon, one of the world’s leading geophysicists, helped create the field of plate tectonics. A devout Catholic and spiritual thinker, he raised his family in intentional communities centered around people with mental disabilities.

Le Pichon has come to think of caring attention to weakness as an essential quality that allowed humanity to evolve.

Kingsolver describes an adventure her family undertook to spend one year eating primarily what they could grow or raise themselves. As a citizen and mother more than an expert, she turned her life towards questions many of us are asking.
