Gerhard Schurz on Universal Sentence - Dictionary of Arguments
92 Notation: II- : "follows logically". Explanation scheme/logical form/explanation/Schurz: strict all proposition & singular proposition II- singular proposition. All A are K and a is A II- a is K. Falsification scheme/falsification/logical form/Schurz: FS I: singular proposition falsifies strict universal sentence. singular sentence II- negation of strict universal sentence a is A and not K II- not all A are K FS II: existence sentence falsifies strict all proposition There is an A that is not a K II- not all A are K. I 93 Syntax/Semantics/Sentence/Characterization/Schurz: The above characterizations of sentence types are syntactic in nature. They are not always invariant to L equivalent transformations. Ex The singular sentence Fa is L equivalent to the all-sentence (x)(x = a > Fx) (all x that are identical with a are F). All proposition: but this proposition is not an all proposition in the semantic sense, since it only says something about the individual a. Invariance/property/Schurz: for sentences to express genuine properties of the corresponding propositions, they must be invariant to L equivalent sentence transformation. L-equivalent/(s): transformation that yields equivalent sentences within the language L. Thus, not arbitrary transformation. L equivalent sentences express the same proposition. Solution/Hempel/Oppenheim: method of essential sentence types. An all-sentence is genuine only if it is not L equivalent to a singular sentence. >Laws of Nature/Schurz._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
