I think you may be taking things a little too literally.
In the realm of romantic relationships, people are very fond of asking if certain things are “possible.” For example: “Is it possible for former lovers to become friends?” Or: “Could my ex-girlfriend, who ran off with my best buddy, ever come crawling back to me, and we’ll live happily ever after?”
I’m not a magic 8-ball; I can’t predict the future. People have free will, and are known to act in all sorts of ways, rational and irrational. And sometimes — very occasionally — things which would seem to be extremely unlikely or stand an exceedingly small chance of succeeding actually end up working out quite well.
And so, in response to such questions, I often begin by saying: “Well, just about anything is ‘possible.’”
I don’t mean, of course, that perhaps tomorrow the sun will rise in the West, or that the ex-girlfriend under discussion might miraculously grow a second head. I’m assuming that the person I’m speaking to is keyed in to reality enough to understand at least generally — metaphysically— what is possible, and am saying that within that context neither I nor anyone else can make any definite statements about what will happen.
One can cite statistics, and one can speak of degrees of likelihood. But it’s very difficult, outside of the aforementioned metaphysical context, ever to say that something is truly _im_possible.
This does not mean that every “possibility” one can dream up is on equal footing with all others; often far from it. If I asked you if it were possible for Bill Clinton to start telling the truth and become an Objectivist, you’d be hard pressed, strictly speaking, to say that it isn’t.
You’d also be well within your rights to question why I’m bringing this “possibility” up — and to demand to know what evidence I have to indicate that this is something even worth considering.
In any kind of communication, what’s most important is not that a person be absolutely, literally correct in every statement he makes, but that the meaning of his words is clear, and is understood by those he’s speaking to. 99% of the time, when someone says “anything is possible,” he means it in exactly the way I’ve described here. The only person who wouldn’t understand that is someone who’s deliberately looking to pick a fight.
