If you had no new technology, and you powered society as we do today - mostly by fossil fuels - you'd have only two choices: Doom yourself to horrific climate change by burning all that carbon and releasing all that CO2. Or power down society, reducing total energy usage around the planet.

The Constitution that I interpret and apply is not living, but dead, or as I prefer to call it, enduring. It means, today, not what current society, much less the court, thinks it ought to mean, but what it meant when it was adopted.

The human race's prospects of survival were considerably better when we were defenceless against tigers than they are today when we have become defenceless against ourselves.

Today the world changes so quickly that in growing up we take leave not just of youth but of the world we were young in.

When I came into office, people said, 'Billionaire? How do they live? What do they eat? How do they sleep?' Today, they see me on the subway coming uptown. A couple of people say hi, some people smile and nod. Some people just sleep. It's not an issue.

But I am convinced that those Jews who stand aside today with a malicious smile and with their hands in their trousers' pockets will also want to dwell in our beautiful home.

I don't want to say too many words about the magic of the Cube, because it's basically a mystery. It's like the Mona Lisa smile. It's both complex and very simple at the same time. And, well, people like it. Even today.

I believe that science is the engine of prosperity, that if you look around at the wealth of civilization today, it's the wealth that comes from science.

What we see today is an American economy that has boomed because of policies and developments of the 1950s and '60s: the interstate-highway system, massive funding for science and technology, a public-education system that was the envy of the world and generous immigration policies.

We should remember that there was once a discipline called natural philosophy. Unfortunately, this discipline seems not to exist today. It has been renamed science, but science of today is in danger of losing much of the natural philosophy aspect.

It seems to me that socialists today can preserve their position in academic economics merely by the pretense that the differences are entirely moral questions about which science cannot decide.

If I may take the liberty to speak for science at least, today his name and his prizes are without a peer in the world. He not only elevates science but he influences it as well.

Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today - but the core of science fiction, its essence has become crucial to our salvation if we are to be saved at all.

The humanities need to be defended today against the encroachments of physical science, as they once needed to be against the encroachment of theology.

'Snow White' is an old fairy tale, so obviously the idea of vanity and obsession with youth is long-standing. With today's science, people have become crazy with trying to move their face around. It's bizarre.

Bush reiterated his stand to conservatives opposing his decision on stem cell research. He said today he believes life begins at conception and ends at execution.

The science of today is the technology of tomorrow.

If you live with someone that is depressed, the truth of it - it's not that dramatic, it's just a bit, kind of, 'Here we go, this is what we're doing today. This is sad. But we're gonna get through it.'

Even today, England is a very repressed, repressive country, and there's pressure to be kind of a certain way, so people do things that ultimately make them sad.

Nowadays you really have to pump out that blockbuster in order to have the luxury of getting a body of work, and that's sad because the work suffers. Today everything is based on money. The older actors, they inspire me.

The president we have today is a typical Washington politician that's prone to hyperbole and decisiveness and false outrage. And I think it's very sad - very sad to watch.

All the things that happen to people in the industry today, the actors, what they have to put up with, all the people wanting to know every single moment of their lives - I think it's really sad.

It's sad - it's sad for us old enough to remember when directors ruled, and films were substantially better than they are today. But it's hard to argue with those kinds of grosses.

It is a sad commentary that today we face a choice between having schools that are a monument to our past - or schools that will be the lifeblood of our future. But since that is our choice, let us resolve to choose wisely.
