The day I made that statement, about the inventing the internet, I was tired because I'd been up all night inventing the Camcorder.

A zebra does not change its spots.

I think George W. Bush has a warm, engaging personality. But, you know, the presidency is more than just a popularity contest.

Iraq's search for weapons of mass destruction has proven impossible to deter and we should assume that it will continue for as long as Saddam is in power.

Winston Churchill aroused this nation in heroic fashion to save civilisation in World War Two. We have everything we need except political will, but political will is a renewable resource.

Verbosity leads to unclear, inarticulate things.

When you have the facts on your side, argue the facts. When you have the law on your side, argue the law. When you have neither, holler.

The presidency is more than a popularity contest.

The first less is this: take it from me, every vote counts.

During my service in the United States Congress, I took the initiative in creating the Internet.

We need to remake the Democratic party. We need to remake America.

The Bush administration works closely with a network of rapid response digital brownshirts who work to pressure reporters and their editors for 'undermining support for our troops.'

Airplane travel is nature's way of making you look like your passport photo.

I pledge to you today that as president, in my first budget, I will introduce the largest increase in special education ever.

As I have said for many years throughout this land, we're borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the future of human civilization. Every bit of that has to change.

I have absolutely no plans and no expectations of ever being a candidate again.

Hey, you know what, I've gotta go on that 'Letterman' show. That show is so lame.

I took the initiative in moving forward a whole range of initiatives that have proven to be important to our country's economic growth, environmental protection, improvements in our educational system.

While President Bush likes to project an image of strength and courage, the real truth is that in the presence of his large financial contributors, he is a moral coward.

No matter how hard the loss, defeat might serve as well as victory to shake the soul and let the glory out.

The heart of the security agenda is protecting lives - and we now know that the number of people who will die of AIDS in the first decade of the 21st Century will rival the number that died in all the wars in all the decades of the 20th century.

Our world faces a true planetary emergency. I know the phrase sounds shrill, and I know it's a challenge to the moral imagination.

I have made good judgments in the past. I have made good judgments in the future.

How could this Y2K be a problem in a country where we have Intel and Microsoft?

A president who breaks the law is a threat to the very structure of our government.

Our democracy, our constitutional framework is really a kind of software for harnessing the creativity and political imagination for all of our people. The American democratic system was an early political version of Napster.

We're all capable of mistakes, but I do not care to enlighten you on the mistakes we may or may not have made.

As president, I will bring all the parties and stakeholders together. I am going to come up with a solution that respects the environment and does not cause an upheaval in the economy.

George Bush taking credit for the wall coming down is like the rooster taking credit for the sun rising.

The day I made that statement, about the inventing the internet, I was tired because I'd been up all night inventing the Camcorder.

I think the cost of energy will come down when we make this transition to renewable energy.

America's political system has evolved over the last 50 years in ways that have enhanced the power of business lobbies.

As human beings, we are vulnerable to confusing the unprecedented with the improbable. In our everyday experience, if something has never happened before, we are generally safe in assuming it is not going to happen in the future, but the exceptions can kill you and climate change is one of those exceptions.

CO2 is the exhaling breath of our civilization, literally... Changing that pattern requires a scope, a scale, a speed of change that is beyond what we have done in the past.

Civil disobedience has an honourable history, and when the urgency and moral clarity cross a certain threshold, then I think that civil disobedience is quite understandable, and it has a role to play.

I am Al Gore, and I used to be the next president of the United States of America.

I did very extensive diligence on Al Jazeera English, the network from which Al Jazeera America is going to be derived, and it's really very clear that they have long since established a reputation for excellence and integrity and objectivity.

I do genuinely believe that the political system is not linear. When it reaches a tipping point fashioned by a critical mass of opinion, the slow pace of change we're used to will no longer be the norm. I see a lot of signs every day that we're moving closer and closer to that tipping point.

I drive a hybrid, and we've changed our light bulbs and windows and installed solar panels and geothermal ground source heat pumps and most everything else.

I have always been fascinated with those who try to look over the horizon and see things that are coming at us.

I remember as a boy when the conversation on civil rights was won in the South. I remember a time when one of my friends made a racist joke and another said, 'Hey man, we don't go for that anymore.'

I see myself in the mold of Rin Tin Tin. It didn't go to his head either.

I take no pleasure in the fact that the scientific predictions I've relayed to popular audiences turn out to be true.

I think it's harder for people than it should be. But as more and more of us become carbon neutral and change the patterns in our lives to be part of the solution instead of part of the problem, we are now beginning to see the changes in policy that are needed.

I think that more diversity is a good thing, and fresh points of view articulated by people who are committed to excellence in journalism is a beneficial change in the American media landscape.

I was in elective politics for 24 years. I've made four national races, two for President, two for Vice President. I have found there are other ways to serve, and I'm enjoying them.

I'm naturally an optimist, but my basis for hope is rooted in my understanding of human nature.
