| Donkey sentences, philosophy: term for logical problems, which preferably, but not essentially refer to donkeys. An early example is Buridan's donkey. A modern donkey sentence is "Geach's donkey" "Anyone who has a donkey beats it." Formal logic is here too rigid to map the possible limiting cases that are not problematic for the everyday language. See also existential quantification, universal quantification, range, scope, quantification, quantifiers, brackets, branched quantifiers._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
