I am not sure that Frege is a good candidate for extremism in denying the
availability of de re (or 'objectual') readings of oblique contexts. But I
doubt that Jean Buridan, in countenancing only suppositio personalis and
suppositio materialis to the exclusion of suppositio simplex, could make
sense of de re readings of statements concerning round squares and other
chimerae. Arguably, on any view that interprets terms as denoting concepts
in oblique contexts, "nothing can be said truly about that, which does not
exist." (Alonzo Church)
