  2. Logical form - Wikipedia

    en.wikipedia.org/wiki/Logical_Form

    In an ideal formal language, the meaning of a logical form can be determined unambiguously from syntax alone. Logical forms are semantic, not syntactic constructs; therefore, there may be more than one string that represents the same logical form in a given language. [1] The logical form of an argument is called the argument form of the argument.

  3. Interpretation (logic) - Wikipedia

    en.wikipedia.org/wiki/Interpretation_(logic)

    The connectives are usually taken to be logical constants, meaning that the meaning of the connectives is always the same, independent of what interpretations are given to the other symbols in a formula. This is how we define logical connectives in propositional logic: ¬Φ is True iff Φ is False. (Φ ∧ Ψ) is True iff Φ is True and Ψ is True.

  4. Logic - Wikipedia

    en.wikipedia.org/wiki/Logic

    A proposition is logically true if its truth depends only on the logical vocabulary used in it. This means that it is true in all possible worlds and under all interpretations of its non-logical terms, like the claim "either it is raining, or it is not". [15] These two definitions of formal logic are not identical, but they are closely related.

  5. Logical form (linguistics) - Wikipedia

    en.wikipedia.org/wiki/Logical_form_(linguistics)

    In generative grammar and related approaches, the logical form (LF) of a linguistic expression is the variant of its syntactic structure which undergoes semantic interpretation. It is distinguished from phonetic form , the structure which corresponds to a sentence's pronunciation.

  6. Glossary of logic - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_logic

    An informal fallacy in which a conclusion is not logically justified by sufficient or unbiased evidence; drawing a general conclusion from a too-small sample size. Henkin semantics A generalization of standard first-order semantics that allows for models where the range of quantifiers can be restricted, named after Leon Henkin.

  7. Semantics of logic - Wikipedia

    en.wikipedia.org/wiki/Semantics_of_logic

    This is the most widespread approach, and is based on the idea that the meaning of the various parts of the propositions are given by the possible ways we can give a recursively specified group of interpretation functions from them to some predefined mathematical domains: an interpretation of first-order predicate logic is given by a mapping ...

    Writing a closed letter 'O' means that you are a private person and an introvert. If the dot on your 'i' lands high above the letter, you are considered to be imaginative.

  9. Logical reasoning - Wikipedia

    en.wikipedia.org/wiki/Logical_reasoning

    A fallacy is an incorrect argument or a faulty form of reasoning. This means that the premises provide no or not sufficient support for the conclusion. Fallacies often appear to be correct on the first impression and thereby seduce people into accepting and using them. In logic, the term "fallacy" does not mean that the conclusion is false.
