Cr..p, the stupid Google server has mangled my post. Let me try again.

Excuse me, Jesse, but wasn't calling my terminology "non-standard" and
possibly "confused" a rather strong and somewhat deragotary and
condescending statement?

Have you noticed where our disscussion is taking place? In sci.math.
It's not even cross-posted to sci.logic.

So, you call my terminology "non-standard" and possibly "confused" by
sci.math standards and then suddenly admit that you don't even know
what is standard terminology among the readers of sci.math and other
mathematicians.

Imagine that I, who hasn't been around many logicians, barged in onto
sci.logic and started calling your and other logicians' posts
"confused" and "non-standard". How would you take this?

In the last few centuries, mathematicians have been able to develop
zillions of new theories - from differential topology to p-adic numbers

- without ever getting confused or asking help from amateur
philosophers. Never had any problems understanding each other. Why
would we start geting confused now?

Tell me. Imagine that two great mathematicians are in the middle of
talking about some abelian group G. And one of them asks:

- Is it true, J-P, that a + 0 = a for all a in G?
- Yes, Serge, it's true.


What is confusing about that? Who is confused? I am not. Are you?

Should J-P have instead answered:

- Is it true, J-P, that a + 0 = a for all a in G?
- Truth is a semantic concept, Serge. Whether a sentence is true has
to do with the meanings of the terms in the sentence. Instead of trying

to derive new algebraic theorems, let's spend the next 10 years
discussing the meanings of the terms "a", "+", "0", "=", "for", "all",
"in" and "G" in your sentence.


In any case, the original statement of mine which caused so much
opposition and condescention from you and a couple of other people was:


>>>>>> You can pick any axiomatic system you want. In some the
>>>>>> statement 0=1 will be true. In others - false.
>>>>>> As the previous poster told you, take the usual axioms
>>>>>> of integers, including inductive ordering, and let the
>>>>>> symbol "=" denote what we usually denote as "<".
>>>>>> Then "0=1" is a correct statement.

Wasn't this saying what you now say:

> with the meanings of the terms in the sentence.
