  3. David Harrah (1985). A Logic of Message and Reply. Synthese 63 (3):275 - 294.
    In this paper we sketch a logic of message and reply. The logic is intended for application in a wide variety of situations, not restricted to the two-person, turn-taking situation. Each message has a body and a vector; the vector specifies the from, to, and the like. To reply to a message, it suffices to give either (1) a complete reply to the body or (2) a corrective reply to at least one presumption derivable from the vector. We discuss the (...)

    If the currently available theories of semantic information and utility-expectation are to be applied in a satisfactory way, they must be combined with a message-processing procedure. This paper presents a model of communication within which such a procedure can be defined. In this model the sender's messages arrive over a period of time, the receiver can reject some messages and retain others, the receiver can change his mind in various ways, and the receiver can apply various evaluation functions to a (...)

  24. David Harrah (1961). A Logic of Questions and Answers. Philosophy of Science 28 (1):40-46.
    A logic of questions and answers exists within the logic of statements, if we make the following identifications (roughly): "Whether" questions are identified with true exclusive disjunctions, and "which" questions are identified with true existential quantifications. The question-and-answer process is interpreted as an information-matching game. The question mark is not needed except as a device of abbreviation. Complete and partial answers can be distinguished and various relations of relevance, independence, and resolution defined.

    he notion of linguistic adequacy (the adequacy of sentences to express or describe) is explicated in terms of a set theoretical model of the communication situation. Roughly: a message is adequate to the degree it answers the receiver's questions. Adequacy is distinguished from openness, in such a way that a message can be both completely adequate in a communication event and also “inexhaustibly open”;. Using this explication it is possible to translate and clarify several familiar philosophical theses concerning the adequacy (...)
