  2. Laws of Form - Wikipedia

    en.wikipedia.org/wiki/Laws_of_Form

    The Markable Mark, an introduction by easy stages to the ideas of Laws of Form; The BF Calculus and the Square Root of Negation by Louis Kauffman and Arthur Collings; it extends the Laws of Form by adding an imaginary logical value. (Imaginary logical values are introduced in chapter 11 of the book Laws of Form.)

  3. Boolean algebra (structure) - Wikipedia

    en.wikipedia.org/wiki/Boolean_algebra_(structure)

    The term "Boolean algebra" honors George Boole (1815–1864), a self-educated English mathematician. He introduced the algebraic system initially in a small pamphlet, The Mathematical Analysis of Logic, published in 1847 in response to an ongoing public controversy between Augustus De Morgan and William Hamilton, and later as a more substantial book, The Laws of Thought, published in 1854.

  4. Boolean algebra - Wikipedia

    en.wikipedia.org/wiki/Boolean_algebra

    The laws listed above define Boolean algebra, in the sense that they entail the rest of the subject. The laws complementation 1 and 2, together with the monotone laws, suffice for this purpose and can therefore be taken as one possible complete set of laws or axiomatization of Boolean algebra. Every law of Boolean algebra follows logically from ...

    en.wikipedia.org/wiki/List_of_rules_of_inference

    Each logic operator can be used in an assertion about variables and operations, showing a basic rule of inference. Examples: The column-14 operator (OR), shows Addition rule : when p =T (the hypothesis selects the first two lines of the table), we see (at column-14) that p ∨ q =T.

  6. Law of thought - Wikipedia

    en.wikipedia.org/wiki/Law_of_thought

    The laws of thought are fundamental axiomatic rules upon which rational discourse itself is often considered to be based. The formulation and clarification of such rules have a long tradition in the history of philosophy and logic. Generally they are taken as laws that guide and underlie everyone's thinking, thoughts, expressions, discussions, etc.

  7. Laws of logic - Wikipedia

    en.wikipedia.org/wiki/Laws_of_logic

    Law of logic may refer to: Basic laws of Propositional Logic or First Order Predicate Logic; Laws of thought, which present first principles (arguably) before reasoning begins; Rules of inference, which dictate the valid use of inferential reasoning

  8. List of axiomatic systems in logic - Wikipedia

    Intermediate logics are in between intuitionistic logic and classical logic. Here are a few intermediate logics: Jankov logic (KC) is an extension of intuitionistic logic, which can be axiomatized by the intuitionistic axiom system plus the axiom [13].

  9. Outline of logic - Wikipedia

    en.wikipedia.org/wiki/Outline_of_logic

    Logic is the formal science of using reason and is considered a branch of both philosophy and mathematics and to a lesser extent computer science. Logic investigates and classifies the structure of statements and arguments, both through the study of formal systems of inference and the study of arguments in natural language .
