I believe there is a distinction between
John said furze is not gorse.
John said "Furze is not gorse".
in the former, I describe John's dicta/beliefs using my words. In the
latter, I report his words/beliefs using his words. I take de dicto
to be the former.

I'll switch terminology if you suggest some. The problem seems to be
in our conception of what de dicto is.

How come? I don't see them as having a different status. Both Pierrean
London and Pierrean Londres are concepts/categories/kinds. Whether
things in the real world actually instantiate them is neither here nor

Sorry for having taken so many messages to succeed in formulating
my thought in a manner you can assent to!
