The principle may be invoked to make sense of a speaker's utterances when one is unsure of their meaning. In particular, Quine's use of the principle gives it this latter, wide domain. Since the time of Quine, other philosophers [who?] have formulated at least four versions of the principle of charity. These alternatives may conflict with one ...
An existential graph is a type of diagrammatic or visual notation for logical expressions, created by Charles Sanders Peirce, who wrote on graphical logic as early as 1882, [1] and continued to develop the method until his death in 1914.
A logical graph is a special type of graph-theoretic structure in any one of several systems of graphical syntax that Charles Sanders Peirce developed for logic.. In his papers on qualitative logic, entitative graphs, and existential graphs, Peirce developed several versions of a graphical formalism, or a graph-theoretic formal language, designed to be interpreted for logic.
Illustration of charity, c. 1884. Charity is the voluntary provision of assistance to those in need. It serves as a humanitarian act, and is unmotivated by self-interest. Various philosophies about charity exist, with frequent associations with religion.
In the mathematical field of model theory, the elementary diagram of a structure is the set of all sentences with parameters from the structure that are true in the structure. It is also called the complete diagram .
First-order logic—also called predicate logic, predicate calculus, quantificational logic—is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science. First-order logic uses quantified variables over non-logical objects, and allows the use of sentences that contain variables.
In model theory, a branch of mathematical logic, the diagram of a structure is a simple but powerful concept for proving useful properties of a theory, for example the amalgamation property and the joint embedding property, among others.
Mereology (/ m ɪər i ˈ ɒ l ə dʒ i /; from Greek μέρος 'part' (root: μερε-, mere-) and the suffix -logy, 'study, discussion, science') is the philosophical study of part-whole relationships, also called parthood relationships.
