The introduction of the chapter on "Generalized Quantifiers and Natural Language" highlights the historical development of the study of generalized quantifiers, initiated by Polish logician Andrej Mostowski in 1957. The work has since expanded to over 200 research papers, focusing on cardinality and topological quantifiers, which have broader implications for natural language understanding. The standard first-order logic quantifiers (∀ and ∃) are found to be inadequate for expressing certain natural language sentences and for capturing the syntactic structure of quantified sentences in natural language. This has led to the development of generalized quantifiers, which offer new insights into the nature of quantifiers and their relationship to natural language syntax. The chapter is structured into several sections. Section 1 introduces the concept of generalized quantifiers and their relevance to English syntax. Section 2 develops a logic that includes generalized quantifiers. Section 3 explores the formal relationship between this logic and a fragment of English syntax. Section 4 delves into the broader implications of generalized quantifiers for natural language theory. Section 5 draws conclusions about the relationship between syntax, semantics, and logic. The paper also includes four appendices that provide additional details and proofs. The first section discusses the nature of generalized quantifiers and their relationship to English syntax, emphasizing that familiar quantifiers like ∀ and ∃ are atypical and have special properties. Examples from mathematics are used to illustrate the general features of quantifiers, such as "There are only a finite number of stars" and "More than half of John’s arrows hit the target." The section also highlights that many quantifiers cannot be defined using first-order ∀ and ∃, underscoring the need for generalized quantifiers to capture the complexity of natural language.The introduction of the chapter on "Generalized Quantifiers and Natural Language" highlights the historical development of the study of generalized quantifiers, initiated by Polish logician Andrej Mostowski in 1957.
