These are the times that try men’s souls, and they’re trying ours now,” begins Rabbi Lord Jonathan Sacks, quoting Thomas Paine, in an electrifying talk about how we can face the future without fear if we face it together.

It’s a fateful moment in history. We’ve seen divisive elections, divided societies and a growth of extremism — all of it fueled by anxiety, uncertainty and fear. The world is changing faster than we can bear, and it’s looking like it’s going to continue changing faster still. Sacks asks: “Is there something we can do to face the future without fear?”

One way into this question is to look to what people worship. Some people worship many gods, some one, some none. In the 19th and 20th centuries, people worshiped the Aryan race, the Communist state and many other things. Future anthropologists, Sacks says, will take a look at the books we read on self-help, at how we talk about politics as a matter of individual rights, and at “our newest religious ritual: the selfie” — and conclude that we worship the self.

This worship of the self conflicts directly with our social nature, and with our need for friendship, trust, loyalty and love. As he says: “When we have too much of the ‘I’ and not enough of the ‘we,’ we find ourselves vulnerable, fearful and alone.”

To solve the most pressing issues of our time, Sacks says, we need to strengthen the future us in three dimensions: the “us of relationship,” the “us of responsibility” and the “us of identity.”

Starting with the “us of relationship,” Sacks takes us back to his undergraduate days studying the philosophy of Nietzsche, Schopenhauer, Sartre and Camus. Full of ontological uncertainty and existential angst, Sacks describes himself as self-obsessed and thoroughly unpleasant to know. Then he saw a girl who was everything he wasn’t. “She radiated sunshine, emanated joy,” he says. They met, talked and forty-seven years of marriage later, Sacks finds himself living proof that it’s the people not like us who make us grow.
