Dear Jon, Howard, Folks--

Sm(wh)ile I've found you on a lighter note--

Let's explicitly suppose (as the above supposition does seem to suppose)
that not only is life real and earnest but that things move about in
space and forward in time sometimes combining with other things to form
more complex things.   So what are the properties of things and what are
the properties of space-time?  Are they the same?  Is space-time a thing?
 Is mass a property of things or space?   Do things change or only their
positions in time and space?   Is deduction (or more broadly logic) just
a definition of space-time, just a definition of things or just a
relatively fixed set of rules for deciphering the meaning of words in
terms of our vague presuppositions about the nature (human scope) of
things and space-time upon which our language use seems to float?  Or are
my puzzlements just an example of the ways in which we disagree about the
meaning of some expressions --just more sound and fury.  Is language a
presumption or a conclusion?  Or is a presumption and a conclusion really
just the same thing in a different time and place?

"And would it have been worth it, after all,
Would it have been worth while,
After the sunsets and the dooryards and the sprinkled streets,
After the novels, after the teacups, after the skirts that trail along
the 
	floor--
And this and so much more?---
It is impossible to say just what I mean!
But as if a magic lantern threw the nerves in patterns on a 
	screen:
Would it have been worth while
If one, settling a pillow or throwing off a shawl,
And turning toward the window, should say:
	"That is not it a all,
	That is not what I meant, at all."

(T. S. Eliot -The Love Song of J. Alfred Prufrock)
