Abstract
The main purpose of the paper is to connect some kind of dialetheism to the use of complex truth values, with new definitions of basic truth-functional connectives that allow for p, \(\backslash \)not p to both be true. ‘True’ is interpreted as \(\left| p \right| = 1\), ‘False’ as \(\left| p \right| = 0\); other values are dispensed with. New definitions of basic truth-functional connectives then allow for “p and not p” to be true. A propositional logic is discussed with the set of connectives including negation, conjunction, disjunction, implication, concordance, discordance, complementary, and equivalence. The authors introduce truth values of propositions, which belong to a subset E, of an uncountable semi-ring F and valuations of propositions, which can be obtained from truth values with the help of a function \(V:E \rightarrow \left[ {0,1} \right] \) satisfying simple properties. Finally, a paraconsistent Boolean logic is introduced.
