I am not an optimist. I'm a very serious possibilist. It's a new category where we take emotion apart and we just work analytically with the world.

For the last several years and culminating in six months in orbit next year, I've been training for my third space flight. This one is almost in a category completely different than the previous two, specifically to live in on the space station for six months, to command a space ship and to fly a new rocket ship.

I think there are going to be a bunch of tablet-like devices. It's really a different product category.

In Shakespeare, unique individuals repudiate the stereotypes demanded by the structure of the play: Shylock commands our sympathy, Barnardine refuses to be hanged. Individuals trump the category.

Museums are like sports stadiums, hotels and hospitals: they are in the category of captive-audience dining.

It seems that 'rocket scientist' is a job category that's here for the long haul, like 'mortician.' But all this activity masks an important point: rockets are not a terribly efficient way to lift things into space.

When we run out of them upstairs, I've been known to appropriate some from our greenroom, pocketing a few with one hand as I smile and greet our guests with the other. One time, Dave Zinczenko of 'Eat this, Not That!' fame, busted me in the act. The cookies apparently fall in the 'not that' category. I made a note of it.

There does not exist a category of science to which one can give the name applied science. There are science and the applications of science, bound together as the fruit of the tree which bears it.

One of the sad commentaries on the way women are viewed in our society is that we have to fit one category. I have never felt that I had to be in one category.

Birtherism is a fringe issue that's way out of the mainstream, and it's disturbing when you see people you... have some level of respect for, whether it's members of Congress or even Donald Trump, falling into that category.

That's one of my pet peeves. People always want to put something into a category - this one or that one. You know, a great song is a great song.

Laughter, and the broader category of humor, are key elements in helping us go on with our life after a loss.

When I say there is no such crime as date rape I am saying what is true. There isn't a specific legal category of date rape and I wanted to make that point in order to ensure that people don't use this to obscure the difference between real sexual violence and, you know, things that have gone wrong.

Intelligence is a moral category.

And as - funny enough, it actually became - so I've always wanted to be a Guinness world record holder. And believe it or not, before I made this there was not a category for world's largest Nerf gun, but there is now.

There are people who intensely clutch an idea that yoga is a higher system, not to be lowered to the weight loss or even fitness category. This is the same kind of clutching that has kept yoga part of a tightly knit club for so long since its introduction in America.

I don't think it's anything you ever get used to... for many years, I could never sort of put my name in the same sort of category as the word 'famous' or anything like that. And I just found it very uncomfortable... if you get used to it, then something must be wrong.

I've been through natural disasters. I lived down in Miami and was down there for Hurricane Andrew which was a Category 5. There were members of my family that thought they were going to die. Everyone was in the bathtub.

I think the environment should be put in the category of our national security. Defense of our resources is just as important as defense abroad. Otherwise what is there to defend?

I grew up as an artist. Science fiction allows for design and creatures and guns and all the stuff that I like as well. So I think most of the films I make, I'm sure, will be in that category. But I can also see myself making a film like 'Black Hawk Down,' and I could also totally do horror.

I am extremely excited to develop and design a brand representative of my life, experiences and style. Working closely with Cherokee will help establish a worldwide presence with best-in-class retailers and category leaders.

When we started, our style of music wasn't on MTV. It wasn't cool, and it wasn't popular. The only bands who were even kind of similar were Blink-182 and Green Day. But we don't sound like those bands, even if people throw us in that category now.

And someone, somewhere, was having an even worse time of it than me. I tried to keep that in mind. No matter how crappy your life, someone will probably beat you in the my-life-is-crap category. Not that I don't let myself whine a little now and then, but sometimes it's good to keep your misery in perspective

"In the course of my intellectual life I experienced very acutely the problem of whether it isn't actually presumptuous to say that we can know the truth - in the face of all our limitations. I also asked myself to what extent it might not be better to suppress this category. In pursuing this question, however, I was able to observe and also to grasp that relinquishing truth doesn't solve anything but, on the contrary, leads to the tyranny of caprice. In that case, the only thing that can remain is really what we decide on and can replace at will. Man is degraded if he can't know truth, if everything, in the final analysis, is just the product of an individual or collective decision.
