“The world needs more Edwin Morgans, people who can take the language and swing it round their heads and don’t care what you think.”

Wishful thinking is not sound public policy.

The great music for so many artists – the Beatles, the Rolling Stones – was always at the moment when they were closest to pop. It would be easy for U2 to go off and have a concept album, but I want us to stay in the pop fray.

So far as we know, Earth is the only planet which supports life, and it is the only planet on which we can survive.

The overarching factor to me is if we can’t be kind to each other, we won’t be kind to the planet.

When we imagine the world a century from now, when we look our great grandchildren in the eye and see them smiling back at us because they know we cared for them, we smile too!

Anarchism may be described as the doctrine that all the affairs of men should be managed by individuals or voluntary associations, and that the State should be abolished….. Nor does the Anarchistic scheme furnish any code of morals to be imposed upon the individual. “

We are all born bonded to nature; that’s why we put depictions of flowers and forests, rather than bulldozers or log piles, on our walls.

I will be Green until the day I die, if not for a long time after.

Humans are mentally sick with a disease called fear.

With a small fraction of the hundreds of billions of dollars spent on the Iraq war, the US and Australia could ensure every starving, sunken-eyed child on the planet could be well fed, have clean water and sanitation and a local school to go to.

Australia must prioritise education spending. It is not a question of whether or not we have the money, it is a question of how we choose to spend it.

Years ago I resolved that because I had no ancestry myself I would leave a record of which my children would be proud, and which might encourage them to still higher effort

Never want something without expecting it

In the end, climate change is a math problem.

Whereas our common past, out of Africa, saw a global diaspora of humankind, our common future depends on a global coming together and consensus, resulting in a more equitable distribution of the Earth’s largesse.

In securing the future of the planet, we secure happiness for ourselves. One of the aims of the Greens is to turn around the tide of pessimism amongst the young people of the world.

We simply need to believe in the power that’s within us, and use it.

Ultimately, you have to pursue your own path, not someone’s idea of the right path. You need to stay on your path.

Just because there’s a trillion places to put an idea doesn’t mean you don’t need an idea in the first place

Ambition makes more trusty slaves than need

Put simply, the rich pay a lot of taxes as a total percentage of taxes collected, but they don’t pay a lot of taxes as a percentage of what they can afford to pay, or as a percentage of what the government needs to close the deficit gap.

I drag a lot of stuff round with me that I don’t need.

I think for me, home needs to be a sanctuary. I need to feel like I’ve escaped the day when I get home.

You know how misleading an image is. You see an image in the newspaper, if they left the caption off, good luck knowing what’s going on. There is something inherently misleading about images, so they need annotation.
