The hardest theme in science fiction is that of the alien. The simplest solution of all is in fact quite profound—that the real difficulty lies not in understanding what is alien, but in understanding what is self. We are all aliens to each other, all different and divided. We are even aliens to ourselves at different stages of our lives. Do any of us remember precisely what it was like to be a baby?

I think that for science fiction, fantasy, and even horror to some extent, the differences are skin-deep. I know there are elements in the field, particularly in science fiction, who feel that the differences are very profound, but I do not agree with that analysis. I think for me it is a matter of the furnishings. An elf or an alien may in some ways fulfill the same function, as a literary trope. It’s almost a matter of flavor. The ice cream can be chocolate or it can be strawberry, but it’s still ice cream. The real difference, to my mind, is between romantic fiction, which all these genres are a part of, and mimetic fiction, or naturalistic fiction.
George R. R. Martin
All men were alien one to another, at times, not only aliens.
Ursula K. Le Guin
If we discovered that, you know, space aliens were planning to attack and we needed a massive buildup to counter the space alien threat and really inflation and budget deficits took secondary place to that, this slump would be over in 18 months. … There was a Twilight Zone episode like this in which scientists fake an alien threat in order to achieve world peace. Well, this time, we don't need it, we need it in order to get some fiscal stimulus.
Paul Krugman
Some people don't believe in aliens. I do believe in aliens. But I believe they gave up on people a long time ago. Wouldn't you? I think there's a few liberal aliens out there, still hangin' in,
Joe Rogan
Can you believe that a famous science-fiction writer also created a completely true religion involving aliens and spacecraft?
