and / sign / mention / use / Tugendhat: "A and B": on the side of the sign, we do not have to expect the term "p and q" , but the expression ’that p and that q". This is an analogy, in fact. Moreover it is in need of a completion by a predicate - I 297
but the state of affairs that p and the st.o.a. that q are not composed - we need a more general term, that somehow contains composition, but goes beyond it.
Conjunction / Tugendhat: "and" not connecting objects nor states of affairs - it combines nothing at all.
