 The other worlds strategy has been proposed by Graham Priest (2005) and Francesco Berto (2008). Priest calls his theory noneism; Berto names it modal Meinongianism. The term “noneism” has been coined by Richard Routley, and Priest not only takes over the name but also essential features of Routley’s theory (among other things the assumption that basic principles of standard logics, like the principle of contradiction, do not hold without restriction—without, of course, accepting that everything is true).
