From article <2818@client1.DRETOR.UUCP>, by mmt@client1.DRETOR.UUCP (Martin Taylor):

Yes, it certainly is not obvious.  Take two formal syntactic systems,
each of which characterizes a set of statements, and associate to each
statement of the first some statement of the second system as its
interpretation.  We now have a formal semantic system constituted from
syntactic systems.

The argument gains some of its plausibility from an equivocation on the
term `formal', which is sometimes used in its proper sense as meaning
"characterized by reference only to form" and sometimes as meaning
"uninterpreted or not semantic".  (Logicians who study formal semantics
would certainly be surprised to learn that the name of their field is an
oxymoron, as it would be if `formal' meant "not semantic".)
