“Before he died in 2013, the great sociologist Robert Bellah said that his view of everything he’d studied across his life was tilted on its axis by this late recognition: when mammals began to bring forth offspring from the center of their bodies, spiritual life became possible. With apes and far more with humans, the period of necessary parental care—care in order for the offspring to survive—became longer and longer. The long helplessness of the child generated a sphere of softening, experimentation, and creativity in self-understanding and shared life.”
