Lukasiewicz says that only the logical principles stated in schematic
terms belong to logic, and not those given in concrete terms.  The
concrete terms 'man', 'mortal' &c are analogous to the substitution
values of the schematic placeholders 'A', 'B', 'C', which were called
the 'matter' (Greek 'hyle') of the inference.  Thus, according to L.,
Aristotle was the true inventor of logic as we know it, because he was
the inventor of the variable letters as in 'all A is B' &c. 

That seems reasonable.  But on that criterion, do the logical systems of
China and India classify as 'logic'.  I know very little about these
