|Multi-valued Logic||I 487
Multi-valued logic/Brandom: Definition designated: the fact that a statement has any truth value at all. Designation indicates what truth is - designated: requires a definition on the assertion - Definition Multi-valued: embedded content - ((s) a particular one of several possible truth values) - interpretation: assigns two types of value: a) whether designated , b) which multi- value - standard situation: it is defined which multi-values are designated - designation value: everything that plays a role for pragmatic significance of free-standing sentences - bottom-up: Designation > formal validity - Basic principle: the substitution never changes with the same multi-value designation.
Multi- values = equivalence classes from logically derivable sentences - Designation = logical validity.
