“The language of modalities is a transposed language of norms.”
(Related to this quote)
What is the connection between the (alethic) modal sense of must and the normative sense of must.
Carnap uses ‘transposed’ to talk about an unquoted word used in a sentence as a transposed mode of speech (about use of a quoted-word). E.g. “Red is a quality.” vs “ ‘Red’ is a one-place predicate.”
