We can't leave people in abject poverty, so we need to raise the standard of living for 80% of the world's people, while bringing it down considerably for the 20% who are destroying our natural resources.

There would be very little point in my exhausting myself and other conservationists themselves in trying to protect animals and habitats if we weren't at the same time raising young people to be better stewards.

The refugees flee to protect their families from violence; the Europeans, on the other hand, fear for their jobs that they need to feed their families.

You're thinking about putting scientists into small cages and doing research on them. I wish it could happen sometimes.

I don't think that faith, whatever you're being faithful about, really can be scientifically explained. And I don't want to explain this whole life business through truth, science. There's so much mystery. There's so much awe.

Words can enhance experience, but they can also take so much away. We see an insect and at once we abstract certain characteristics and classify it - a fly. And in that very cognitive exercise, part of the wonder is gone. Once we have labeled the things around us we do not bother to look at them so carefully. Words are part of our rational selves, and to abandon them for a while is to give freer reign to our intuitive selves.

But does that mean that war and violence are inevitable? I would argue not because we have also evolved this amazingly sophisticated intellect, and we are capable of controlling our innate behavior a lot of the time.
