The paradox appeared as a minor theorem in a 1963 paper by Frederic Fitch, "A Logical Analysis of Some Value Concepts". Other than the knowability thesis, his proof makes only modest assumptions on the modal nature of knowledge and of possibility. He also generalised the proof to different modalities.
In the end, because Carnap argues that philosophy aims at the logical analysis of the language of science and thus is the logic of science, the theory of the logical syntax can be considered as a definite language and a conceptual framework for philosophy. The logical syntax of language is a formal theory.
Logical reasoning is a mental activity that aims to arrive at a conclusion in a rigorous way. It happens in the form of inferences or arguments by starting from a set of premises and reasoning to a conclusion supported by these premises.
The reason this works can be seen by studying the logical form of the expected answer to the question. This logical form (Boolean expression) is developed below ('Q' is true if the answer to Q is 'yes', 'God' is true if the god to whom the question is asked is acting as a truth-teller and 'Ja' is true if the meaning of Ja is 'yes'):
Boolean analysis was introduced by Flament (1976). [1] The goal of a Boolean analysis is to detect deterministic dependencies between the items of a questionnaire or similar data-structures in observed response patterns. These deterministic dependencies have the form of logical formulas connecting the items.
Philosophical analysis is any of various techniques, typically used by philosophers in the analytic tradition, in order to "break down" (i.e. analyze) philosophical issues. Arguably the most prominent of these techniques is the analysis of concepts , known as conceptual analysis .
In the philosophy of Immanuel Kant, analytic reasoning represents judgments made upon statements that are based on the virtue of the statement's own content. No particular experience, beyond an understanding of the meanings of words used, is necessary for analytic reasoning.
Its goal is to make the logical structure of natural language sentences and arguments explicit. [25] It is mainly concerned with their logical form while their specific content is usually ignored. [26] Logical analysis is a closely related term that refers to the process of uncovering the logical form or structure of a sentence. [27]
