The Conservatives hold rural places because they keep bombarding rural Canada with, "Liberals are a bunch of urban, metropolitan snobs who don't care about you and want to leave you dead by the roadside." We've simply got to go out and say, "they're lying to you about us. We actually care about you more than the other guys, and we're not going to pander to your prejudices - we're going to give hope to your kids."

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

In academic life, false ideas are merely false and useless ones can be fun to play with. In political life, false ideas can ruin the lives of millions and useless ones can waste precious resources. An intellectual's responsibility for his ideas is to follow their consequences wherever they may lead. A politician's responsibility is to master those consequences and prevent them from doing harm. Michael Ignatieff, a former professor at Harvard and contributing writer for the magazine, is a member of Canada's Parliament and deputy leader of the Liberal Party.

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.

Patriotism is the secret resource of a successful society.
