Liberals don't want any part of Canada left behind. I used to give speeches on and on and on about the fact that we don't want to have a country where you think, "my kids have got to move to the city if they're going to have any kind of future." We've been saying that, and we've not got through.

One of the greatest feelings in life is the conviction that you have lived the life you wanted to live-with the rough and the smooth, the good and the bad-but yours, shaped by your own choices, and not someone else's.

An intellectual may be interested in ideas and policies for their own sake, but a politician's interest is exclusively in the question of whether an idea's time has come.

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.

If I am not elected, I imagine that I will ask Harvard to let me back.

The politics of personal destruction, the politics of division, the politics of fear, it's all there. It helps you to define the politics of moderation - the politics of democratic respect, the politics of hope - more clearly.

The Liberal Party of Canada has no monopoly on public service, we have no monopoly on virtue, and we have no monopoly on wisdom.
