There are a lot of young Canadians who want to be politically active at their college or their university who can't go to the party convention, who can't take part in politics, because they're holding down a job to pay their tuition. These are kids who want to do public service, who want to get involved politically, but their financial situation is precarious.

We can't afford to waste people. We can't afford to have people think the game is over before it's begun. We've got to be saying to the Canadian people: you can't tax cut your way to a productive 21st-century economy.

That's what we've got to say, and so we shall.

Tad Homer-Dixon is a rare kind of public intellectual, who combines real expertise with a commitment to communicate to the widest possible readership. In The Ingenuity Gap he wants us all to wake-up to the fearful possibility that our blithe trust in science and technology may be misplaced. Human ingenuity may not be capable of coping with two emerging crises of this century and the next: population growth and environmental despoliation. Read Homer Dixon's wake-up call and you will see the future very differently.

Well, I'm an absolute fan of lacy lingerie. I want to make that perfectly clear.

The disagreeable reality for those who believe in human rights is that there are some occasions-and Iraq may be one of them-when war is the only real remedy for regimes that live by terror.

Living fearlessly is not the same as never being afraid. It's good to be afraid occasionally. Fear is a great teacher.
