Noneism

Noneism is a theory first coined by Richard Routley and appropriated again in 2005 by Graham Priest, which essentially holds that the principle of noncontradiction as well as other logical principles are not truly laws since they do not always hold. At the same time, both Priest and Routley are careful to say that noneism does not hold that everything is true.

Routley's book, Exploring Meinong's Jungle and Beyond: An Investigation of Noneism and the Theory of Items, was published in 1980, while Priest's 2005 book is entitled, Towards Nonbeing: The Logic and Metaphysics of Intentionality.
