Lawvere has many times stressed the need to find a correct "definition" of
large topoi (or topoi of spaces).
It is classical the distinction between
topoi of spaces (large)
versus
space (or spatial) topoi (small)
as for example the large Zariski topos versus the small Zariski topos (or the
same for the etal topology, although in this second case neither is spatial in
the strict technical sense)
I just bring this classical examples for consideration in this thread
e.d.
