I have to admit that, until recently, I was somewhat wary of the (global) warming debate. I believe it is now our responsibility to take the lead on this issue.

So long as I can stay mentally alert - inquiring, curious - I want to keep going. I love my wife and my children, but I don't want to sit around at home with them. We go on safaris and things like that. I can do that for a couple of weeks a year. I'm just not ready to stop, to die.

I've always been more interested in the content of our newspapers, political positions day to day, the thrill of communicating with people through words that I am in the pure business aspects.

The buck stops with me, but I can tick off dozens of very good senior executives that are responsible for hundreds or thousands of people who work for me.

The Internet has been the most fundamental change during my lifetime and for hundreds of years.

My worry about the New York Times is that it's got the only position as a national elitist general-interest paper. So the network news picks up its cues from the Times. And local papers do too. It has a huge influence. And we'd love to challenge it.
