Listing Quotes
Behind the shower curtain, Zooey closed his eyes for a few seconds, as though his own small craft were listing precariously in the wake. Then he pulled back the shower curtain and stared over at the closed door. It was a weighty stare, and relief was not really a great part of it. As much as anything else, it was the stare, not so paradoxically, of a privacy-lover who, once his privacy has been invaded, doesn't quite approve when the invader just gets up and leaves, one-two-three, like that.
J. D. Salinger
Unfortunately, truth is neither a listable nor a decidable property; nor is the truth of a statement of arithmetic. The American logician John Myhill has used the term 'prospective' to characterize those attributes of the world that are neither listable nor decidable. They are properties that cannot be recognized by the application of some formula, made to conform to a rule, or generated by some computer program. They are characterized by incessant novelty that cannot be encompassed by any finite set of rules. 'Beauty', 'ugliness', 'truth', 'harmony', simplicity', and 'poetry' are names we give to some of the attributes of this sort. There is no way of listing all examples of beauty or ugliness, nor any procedure for saying whether or not something possesses either of those attributes, without redefining them in some more restrictive fashion that kills their prospective character.
John D. Barrow
