That's a central part of philosophy, of ethics. What do I owe to strangers? What do I owe to my family? What is it to live a good life? Those are questions which we face as individuals.

Sometimes we know the best thing to do, but fail to do it. New year's resolutions are often like that. We make resolutions because we know it would be better for us to lose weight, or get fit, or spend more time with our children. The problem is that a resolution is generally easier to break than it is to keep.

When diamonds' role in fuelling violent conflict in Africa gained worldwide attention, the diamond industry established the Kimberley process in order to keep ""blood diamonds"" out of international trade.

I'm not overly alarmist about it, but I do think there are some worrying signs, like the growing accumulation of wealth by a very small proportion of the population, plus elections in the US are much more dominated by money than anywhere else calling itself a democracy.

For centuries, America has led the world on a long march toward freedom and democracy. Let's reclaim our clean energy leadership and lead the world toward clean energy independence.

There is no force in the world that can block the powerful march of our army and people, who are holding high the banner of the suns of great Comrade Kim Il Sung and great Comrade Kim Jong Il and continuing to advance under the leadership of the party and with strong faith in sure victory.

Great leaders find a way to rise above politics while at the same time keeping their party's loyalists in the fold.

There are going to be times when we disagree with our leadership, but ultimately, we've got to work hard to pull our leadership to the right and to move a conservative agenda forward and unite as conservatives if we're going to get things done.
