Interrogative logic

from Wikipedia, the free encyclopedia

The erotetics is a logic of the question that, so a discipline with logical and linguistic methods interrogative investigated and issue statements.

Emergence

Formal structures of questions are already established in Aristotle . Richard Whately and Bernard Bolzano provided the first traditional preparatory work. The first approaches to modern interrogative logic in the 20th century come from Kazimierz Ajdukiewicz , Rudolf Carnap , Eugeniu Sperantia , Hans Reichenbach and Nuel Belnap .

A more comprehensive approach to interrogative logic, however, was only presented by Mary Prior and Arthur N. Prior under the title of erotic logic .

Approaches to interrogative logic

Prior / Prior and others distinguish syntactically different types of questions in natural languages:

  • categorical questions ("Are you going to drive the car?")
  • hypothetical questions ("If the sun is shining, would you rather go on foot?")
  • disjunctive questions ("Are you driving or Annegret?")
  • W questions
  • Decision-making questions: yes-no questions, whether questions

These types of questions were parallelized and combined by the priors. When it comes to categorical and hypothetical questions, Urs Egli differentiates between total and partial.

For Felix Cohen every question is synonymous with a function equation (with Cohen: propositional function) with an unknown x. If there are no suitable arguments for x, the question is meaningless.
