Certainly 'the least number not specificable in less than ninteen
syllables' contains less than ninteen syllables. But you have not
shown that it specifies anything, and so specifies something in less
than 19 syllables. See the very end of my lengthy paper 'Epsilon
Calculi', just published in the Journal of the IGPL. (Vol 14, No 4,
2006, pp. 535-590). I there discuss a formal treatment of the same
paradox by Graham Priest, and isolate the corresponding fallacy in
his reasoning.
A bit of a myth has grown up about 'The Logical Paradoxes' that they
are quite intractable conundrums (that is indeed a major source of
the idea behind Priest's paraconsistent logic). But in many cases,
if not all, the problem has merely been a too hasty logical analysis.
If you do not believe me, try getting a contradiction from the
following formal definition of Heterologicality, for instance:
Het'x' iff (EF)((G)(Des('x',G) <-> F=G).-F'x').
You will need the additional assumption that (G)(Des('Het',G) <->
Het=G) at one point, and so the contradiction which is then derivable
merely means that this further assumption cannot be true..
