There have been a number of very credible attempts to devise paraconsistent logics to deal with the problems caused by the unavoidability of contradictions in knowledge bases and elsewhere. This paper suggests a set of principles for generating logical operator semantics which are broadly drawn from classical logic. These lead directly to a paraconsistent logic, LM4, which significantly outperforms other systems and solves the problem for all practical purposes without giving rise to the difficulties inherent in other attempted solutions.
