2. Glossary of logic - Wikipedia

   en.wikipedia.org/wiki/Glossary_of_logic

   The simplest type of formula in logic, consisting of a single predicate applied to a sequence of terms without any logical connectives. atomic sentence A sentence that contains no logical connectives or quantifiers, expressing a basic statement about objects. autological A term that describes itself. For example, the word "short" is autological ...

3. 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 .

4. Sentence (mathematical logic) - Wikipedia

   en.wikipedia.org/wiki/Sentence_(mathematical_logic)

   The following example in first-order logic (=) is a sentence. This sentence means that for every y, there is an x such that =. This sentence is true for positive real numbers, false for real numbers, and true for complex numbers. However, the formula

5. Statement (logic) - Wikipedia

   In the latter case, a (declarative) sentence is just one way of expressing an underlying statement. A statement is what a sentence means, it is the notion or idea that a sentence expresses, i.e., what it represents. For example, it could be said that "2 + 2 = 4" and "two plus two equals four" are two different sentences expressing the same ...

6. List of valid argument forms - Wikipedia

   en.wikipedia.org/wiki/List_of_valid_argument_forms

   In order to evaluate these forms, statements are put into logical form. Logical form replaces any sentences or ideas with letters to remove any bias from content and allow one to evaluate the argument without any bias due to its subject matter. [1] Being a valid argument does not necessarily mean the conclusion will be true. It is valid because ...

7. Term (logic) - Wikipedia

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

   For example, 2+2 is a ground term and hence also a linear term, x⋅(n+1) is a linear term, n⋅(n+1) is a non-linear term. These properties are important in, for example, term rewriting. Given a signature for the function symbols, the set of all terms forms the free term algebra. The set of all ground terms forms the initial term algebra.

8. Logical form - Wikipedia

   en.wikipedia.org/wiki/Logical_Form

   The modern view is more complex, since a single judgement of Aristotle's system involves two or more logical connectives. For example, the sentence "All men are mortal" involves, in term logic, two non-logical terms "is a man" (here M) and "is mortal" (here D): the sentence is given by the judgement A(M,D).

   For example, if the formula () stands for the sentence "Socrates is a banker" then the formula articulates the sentence "It is possible that Socrates is a banker". [127] To include these symbols in the logical formalism, modal logic introduces new rules of inference that govern what role they play in inferences.
