Dear Henry

I will try to focus on the most important issue, semantics versus
pragmatics. I take your last paragraph as my point of departure. In a
previous post you formulated the essence of this paragraph the following
way:

I am not disputing your two-dimensional tables or the technical conclusions
you draw from them. What I am disputing, is that you, from this statistics
can draw *any* positive conclusions regarding the *meaning* of QATAL and
WEQATAL and whether they constitute one or two conjugations. To be able to
do that we must build on particular assumptions, and the conclusions are
not better than the assumptions. We can illustrate this by a quote from
what is snipped:

(RF: ASSUMPTION ONE)

Your words show that to get your two-dimensional table, you assume that
QATAL  and WEQATAL *are* two different morphological categories. As a basis
for your statistical analysis regarding the *use* of QATAL and WEQATAL,
this assumption is not problematic. But as far as *semantics* is concerned,
this assumption makes the situation completely circular, because what shall
be proved is assumed.  My fundamental question was: "Do QATAL and WEQATAL
constitute one or two semantic groups? We cannot answer this semantic
question by pointing to a graphic difference, namely, prefixed waw. A
semantic question can only be answered

To make statistics of the *use* of QATAL and WEQATAL, it is true that the
names of the different areas of use are irrelevant. However, if we want to
use our statistics to fix the *meaning* of the verbs, there are several
problems. To classify Hebrew verbs according to the differences: RT>C (past
reference), RT=C (present reference, perfect reference), and C>RT (future
reference) and call these "semantic categories", builds on the aasumption
that past,present, perfect, and future reference are semantically
distinctive. However, such an assumption is only valid in a tense-language
(where tense is grammaticalized). In such a language we may, for a semantic
analysis, call each group "APPLE", "BANANA", "ORANGE", and "CUMQUAT". But
in a tense-less language, we have to change the names to "APPLE", "APPLE",
"APPLE", and "APPLE". This is so because in a language where tense is not
grammaticalized we cannot ascribe a different *semantic* meaning to verbs
with past, present, perfect, and future reference. True, the function or
use of the verbs is different, and this is described by your analysis. But
this is pragmatics and not semantics.

I conclude that without assumption one (QATAL  and WEQATAL  are two
different morphological categories) there is no "formal statistical
"independence" of a QATAL vs. WEQATAL variable" that can be used to draw
semantic conclusions, and without assumption two (Hebrew has different
semantic categories differentiated by temporal reference) there is no
"semantic meaning variable", namely,"APPLE", "BANANA", "ORANGE", and
"CUMQUAT". So your analysis is excellent for showing pragmatics (that there
is a significant difference in the use of QATAL and 	WEQATAL), but it is
completely useless for  showing semantics.
