 The contemporary study of generalized quantifiers begins with Mostowski (1957) and Lindström (1966) (the entry on  generalized quantifiers  provides a survey of recent developments and applications in logic and natural language). Lindström and Mowstoski began with a generalization of Frege’s conception of a quantifier in at least two dimensions. First, they considered additional unary quantifiers \(Q(A)\), which behave syntactically like \(\forall\) and \(\exists\) but set a different condition on the extension of \(A\). Second, they considered binary quantifiers \(Q(A, B)\), which set a given condition based on a relation between the extensions of \(A\) and \(B\).
