Today we have a health insurance industry where the first and foremost goal is to maximize profits for shareholders and CEOs not to cover patients who have fallen ill or to compensate doctors and hospitals for their services. It is an industry that is increasingly concentrated and where Americans are paying more to receive less.

Is anyone serious about the politics of happiness? David Cameron dipped a toe in the water using the word lightly but denying the hard policies it implies. Labour shies away from it but should take up the challenge.

I always seem to have a vague feeling that he is a Satan among musicians a fallen angel in the darkness who is perpetually seeking to fight his way back to happiness.

Happiness includes chiefly the idea of satisfaction after full honest effort. No one can possibly be satisfied and no one can be happy who feels that in some paramount affairs he failed to take up the challenge of life.

The great thing about being a print journalist is that you are permitted to duck. Cameramen get killed while the writers are flat on the floor.

I've got the greatest job in the world. There's no other job in government where cause and effect is so tightly coupled where you can make a difference every day in so many different ways and in so many different people's lives. It's a great challenge.

When man lives under government he is fallen his worth is gone and his nature tarnished.

I hope we shall crush in its birth the aristocracy of our monied corporations which dare already to challenge our government to a trial by strength and bid defiance to the laws of our country.

I grow plants for many reasons: to please my eye or to please my soul to challenge the elements or to challenge my patience for novelty or for nostalgia but mostly for the joy in seeing them grow.

Our challenge for the future is that we realize we are very much a part of the earth's ecosystem and we must learn to respect and live according to the basic biological laws of nature.
