Disjunction Truth

disjunction truth represents a topic that has garnered significant attention and interest. Disjunction (Stanford Encyclopedia of Philosophy). In logic, disjunction is a binary connective (\ (\vee\)) classically interpreted as a truth function the output of which is true if at least one of the input sentences (disjuncts) is true, and false otherwise. Its supposed connection with disjunctive words of natural language like or has long intrigued philosophers, logicians and linguists.

In this entry we give an overview of logical and ... Disjunction is a binary truth-function, the output of which is a sentence true if at least one of the input sentences (disjuncts) is true, and false otherwise. Disjunction, together with negation, provide sufficient means to define all other truth-functions. Disjunction Disjunction is a binary truth-function, the output of which is a sentence true if at least one of the input sentences (disjuncts) is true, and false otherwise.

The Disjunctive Theory of Perception - Stanford Encyclopedia of Philosophy. For in certain places he says that his Perception-Illusion disjunctions permit a description of what is seen in terms of how the thing looks, thereby allowing the following kind of Perception-Illusion disjunction: ‘ S sees something which looks blue or is having that illusion’ (1973, 61). Causal Theories of Mental Content - Stanford Encyclopedia of Philosophy. Furthermore, because there appears always to be this option of making the content of a term some disjunction of items, the problem has been called “the disjunction problem”.

[6] As was noted above, what unifies causal theories of mental content is some version of the idea that “X”s being causally connected to Xs makes “X”s mean Xs. Similarly, natural Deduction Systems in Logic - Stanford Encyclopedia of Philosophy. ‘Natural deduction’ also designates the type of reasoning that these logical systems embody, and it is the intuition of very many writers on the notion of meaning—meaning generally, but including in particular the meaning of the connectives behind active reasoning—that it is defined by the use of the expression. And for logical expressions like connectives, a salient aspect of their ...

The Turn to Heyting’s Formalized Logic and Arithmetic. Some early results Intuitionistic propositional logic is not a finitely valued logic. Gödel (1932) showed that Heyting’s system for intuitionistic propositional logic cannot be conceived of as a finitely many-valued logic. Apparently unbeknown to Gödel, this confirmed a conjecture of Oskar Becker (1927: 775–777). Intuitionistic Logic (Stanford Encyclopedia of Philosophy).

Another key aspect involves, intuitionistic logic encompasses the general principles of logical reasoning which have been abstracted by logicians from intuitionistic mathematics, as developed by L. Brouwer beginning in his [1907] and [1908]. Because these principles also hold for Russian recursive mathematics and the constructive analysis of E. Bishop and his followers, intuitionistic logic may be considered the ... It's important to note that, the Logic of Conditionals - Stanford Encyclopedia of Philosophy.

A related one is that it makes the conditional interdefinable with Boolean negation, disjunction, and conjunction. A third, among the driving motivations for Frege, Russell and Whitehead, is that it appears adequate to regiment mathematical proofs involving conditional sentences.
