Since propositions are defined as the sharable objects of attitudes and the primary bearers of truth and falsity, this means that the term "proposition" does not refer to particular thoughts or particular utterances (which are not sharable across different instances), nor does it refer to concrete events or facts (which cannot be false).[1] Propositional logic deals primarily with propositions and logical relations between them. These types can include variables, operators, function symbols, predicate (or relation) symbols, quantifiers, and propositional constants.[3] (Grouping symbols such as delimiters are often added for convenience in using the language, but do not play a logical role.) Symbols are concatenated together according to recursive rules, in order to construct strings to which truth-values will be assigned. ./cache/en-wikipedia-org-7948.html ./txt/en-wikipedia-org-7948.txt
