I've worked very hard in this book to keep the lin...

I decided that now is the time to start doing the things that really interest me and I find important. It was in the 10 years of the MacArthur grant that I began working on my first book... and I began putting more work into environmental history.

Federal elections happen every two years in this country. Presidential elections every four years. And four years just isn't long enough to dismantle all the environmental laws we've got in this country.

Introspection and preserved writings give us far more insight into the ways of past humans than we have into the ways of past dinosaurs. For that reason, I'm optimistic that we can eventually arrive at convincing explanations for these broadest patterns of human history.

Communication is a continual balancing act, juggling the conflicting needs for intimacy and independence. To survive in the world, we have to act in concert with others, but to survive as ourselves, rather than simply as cogs in a wheel, we have to act alone.

There is no pleasure to me without communication: there is not so much as a sprightly thought comes into my mind that it does not grieve me to have produced alone, and that I have no one to tell it to.

This communication alone, by the comparison of the antagonisms, rivalries, movements which give birth to decisive moments, permits the evolution of the soul, whereby a man realizes himself on earth. It is impossible to be concerned with anything else in art.

There are people still in the Republican Party that I believe practice the communication of anger, of disappointment, of regret, of pain, of sorrow, of suffering. That's not what the American people want to hear.
