It might be useful to point out that this article is available on the Net:

*.ps format:

ftp://ftp.maths.warwick.ac.uk/pub/papers/dhf/incommensurability.ps

*.pdf format:

ftp://ftp.maths.warwick.ac.uk/pub/papers/dhf/incommensurability.pdf

| and this article has been recycled and adapted as the first section of the
| new Appendix of the 2nd ed of my book (for details, see my posting of
| December 10th), which I there recommend to readers as a new Introduction.
| The original text of the book itself doesn't raise the issue before the
| final section of the discussion of things Greek, where I present the
| evidence concerning the story and assert that it is so insubstantial that
| I haven't discussed it earlier, and haven't embroidered an interpretation
| out of it, since it would distract from my own particular invention which,
| this time, I am trying to broadcast.
|
|
| As you may see,the subtext of my message is that the 'history' of Greek
| mathematics is an arcane intellectual game played according to some
| collection of largely unspoken and continually changing rules. One of my
| main objectives is to introduce a new set of rules and try to persuade
| people to play the game my way. But beware: I've had a few year's practice
| at it, which is why I can volley back many of these queries and objections!
| All of them? - I just don't know, and I might have to refine some of my
| remarks here; they come off the top of my head.

| I also raise my glass this yuletide, in salutation of Julio, creator of
| this list, and to its members.

Oh... Many thanks, David! Right now I'm raising my glass in salutation of
all members of this virtual (and very real) forum!

Cheers! ...
