" Perhaps more sobering, it has also hardwired us to cooperate with and be kind to those who look like our caregivers, who presumably kept us safe. We are more wary of others who look different: these are the unconscious roots of prejudice. Our empathy does not seem to extend to those who are outside our “group,” which is perhaps why the Archbishop and the Dalai Lama are constantly reminding us that we are, in fact, one group—humanity. "
