The semantics of logic refers to the approaches that logicians have introduced to understand and determine that part of meaning in which they are interested; the logician traditionally is not interested in the sentence as uttered but in the proposition, an idealised sentence suitable for logical manipulation.
The book later influenced A. J. Ayer's Language, Truth, and Logic, an introduction to logical positivism, and both the Richards–Ogden book and the Ayer book in turn influenced Alec King and Martin Ketley in the writing of their book The Control of Language, which appeared in 1939, and which influenced C. S. Lewis in the writing of his defence ...
In these examples, the predicate is tall and the QNPs are a girl, many girls, every girl and no girl. The logical meaning of these sentences indicates that the property of being tall is attributed to some form of the QNP referring to girl. Along with the QNP and the predicate, there is also an inference of truth value.
In semantics, pragmatics, and philosophy of language, a question under discussion (QUD) is a question which the interlocutors in a discourse are attempting to answer. In many formal and computational theories of discourse, the QUD (or an ordered set of QUD's) is among the elements of a tuple called the conversational scoreboard which represents the current state of the conversation.
Logical, rational or general grammar was the dominant approach to language until it was supplanted by romanticism. [3] Since then, there have been attempts to revive logical grammar. The idea is today at least partially represented by categorial grammar, formal semantics, and transcendental phenomenology,
Semantics studies meaning in language, which is limited to the meaning of linguistic expressions. It concerns how signs are interpreted and what information they contain. An example is the meaning of words provided in dictionary definitions by giving synonymous expressions or paraphrases, like defining the meaning of the term ram as adult male sheep. [22]
A semantics is a system for mapping expressions of a formal language to their denotations. In many systems of logic, denotations are truth values. For instance, the semantics for classical propositional logic assigns the formula the denotation "true" whenever and are true. From the semantic point of view, a premise entails a conclusion if the ...
The assumption of the autonomy of syntax can be traced back to the neglect of the study of semantics by American structuralists like Leonard Bloomfield and Zellig Harris in the 1940s, which was based on a neo-positivist anti-psychologist stance, according to which since it is presumably impossible to study how the brain works, linguists should ignore all cognitive and psychological aspects of ...
