“If there is a sense of reality, there must also be a sense of possibility. To pass freely through open doors, it is necessary to respect the fact that they have solid frames. This principle, by which the old professor had lived, is simply a requisite of the sense of reality. But if there is a sense of reality, and no one will doubt that it has its justifications for existing, then there must also be something we can call a sense of possibility. Whoever has it does not say, for instance: Here this or that has happened, will happen, must happen; but he invents: Here this or that might, could, or ought to happen. If he is told that something is the way it is, he will think: Well, it could probably just as well be otherwise. So the sense of possibility could be defined outright as the ability to conceive of everything there might be just as well, and to attach no more importance to what is than to what is not.”

“California has a sense of experimentation and a sense of openness—openness to new possibilities.”
interview in Playboy magazine (February 1985 http://www.playboy.co.uk/article/16311/playboy-interview-steven-jobs) <!-- alternate link : http://gizmodo.com/5694765/29+year+old-steve-jobs-extols-californias-virtues-to-playboy-magazine -->
1980s
Context: Woz and I very much liked Bob Dylan's poetry, and we spent a lot of time thinking about a lot of that stuff. This was California. You could get LSD fresh made from Stanford. You could sleep on the beach at night with your girlfriend. California has a sense of experimentation and a sense of openness—openness to new possibilities.

“The difference between reality and fiction? Fiction has to make sense.”
Attributed to an interview on Larry King Live; also quoted in Quotable Quotes (1997) edited by Deborah Deford
Attributed variant: The difference between fiction and reality is that fiction has to make sense.
Clancy here expresses an idea evoked in similar statements made by others, all derived from the orignial made by Lord Byron:
Lord Byron: Truth is always strange; stranger than fiction.
Mark Twain: Truth is stranger than fiction, but it is because fiction is obliged to stick to possibilities, truth isn't.
G. K. Chesterton: Truth must necessarily be stranger than fiction, for fiction is the creation of the human mind and therefore congenial to it.
Leo Rosten: Truth is stranger than fiction; fiction has to make sense. (attributed)
