Our culture is at a critical cusp - a time that requires that we define what it means to be a citizen in a democracy. Within our nation we need to foster a greater sense of collective responsibility.

The academic world is one of the few places where prejudice is supposed to be totally banned, and we're politically correct on everything, but it's still a place where you can attack religion out of utter, complete, bottomless ignorance and not be considered to have done anything wrong.

We never get to the bottom of ourselves on our own. We discover who we are face to face and side by side with others in work, love and learning.

We have imagined ourselves a special creation, set apart from other humans. In the last twentieth century, we see that our povertyis as absolute as that of the poorest nations. We have attempted to deny the human condition in our quest for power after power. It would be well for us to rejoin the human race, to accept our essential poverty as a gift, and to share our material wealth with those in need.

Leaving home in a sense involves a kind of second birth in which we give birth to ourselves.

We're [humans] running great risks of doing things that will not be good for us. The cost can be very high indeed if we reach the point where we can't adapt to our own increasingly rapid adaptations. We run the risk of early extinction. So this certainly isn't a triumphalist story, but it is trying to get at what, in the very long run, leads to the amazing creatures that we are.

"Nothing is ever lost" means that what we are now goes all the way back through natural history. We are biological organisms and not simply computerized brains. By focusing totally on the present, thinking only about science and computers, and forgetting four billion years of life on this planet, we are losing perspective on who and what we are.
