Intuitionistic Type Theory
... In particular, the premisses and conclusion of a logical inference are judgements. The distinction between propositions and judgements was clear from Frege to Principia. These notions have later been replaced by the formalistic notions of formula and theorem (in a formal system), respectively. Contr ...

As seen by logicians, contradiction goes hand in hand with logical inconsistency. ...

In fact, a AND b is TRUE if and only if both a and b are TRUE, as the product of a and b, i.e., ab, is 1 if and only if both a and b are 1; and a AND b is FALSE if and only if either a or b or both are FALSE, a ...
