I don't quite follow this, even as to whether by saying "the contradiction is
obtained by logical negations" you mean to admit exactly that, and so admit A
and B do contradict because one is the negation of the other. "Since you hair
chopping", for example, is not clear or good English.
Certainly I can see no clear argument in your post that supports the view that
A and B do not contradict.

sorry, since you hair chopping
the contradiction is obtained by logical negations
your reading if correct ought to be (meaning the reading of your sentences)
a it is not the case that there is snow here
~a there is snow here
[you may decide to eliminate the space indexical and presume implicit the
termporal one, or fix them to an arbitrary fixed point of choice-
then you have acontradiction

My posts on the following, and the issue of materialism/physicalism as
preferred terminology [which suggested 'World 1' is preferable to either], went
astray last week. I take it these posts were not received on the list. Having
re-subscribed, where I had previously proposed:-
"A. Here there is snow.
B. Here there is no snow.
Assuming "Here" refers to same point in space-time, these A and B contradict."
Adriano then commented:- "strictly they aren't even contradictory".
But they are contradictory and strictly so. A is equivalent to "There is such a
thing as snow here". B is equivalent to the negation of A viz. "There is no
such thing as snow here".
So A is a p, and B is its negation non-p: these do contradict, as any p and its
logical negation contradict.
