Demonstration/Ostension/Ostensive Definition/Brandom: direct line in the common space, extended until it crosses something opaque.
Wittgenstein: that requires many social arrangements - Demonstration as such is unrepeatable.
Referencing/Reference/Brandom: cannot be understood in terms of demonstration, rather the demonstration must be explained in terms of referencing.
Anaphora: it is necessary in order to generate the repeatable from the unrepeatable where co-typicity does not even bear an annullable assumption of coreference and therefore not of (co)-recurrence.
