In particular, propositional semantic networks (exemplified by SNePS) are discussed, it is argued that only a fully intensional, Meinongian semantics is appropriate for them, and several Meinongian systems are presented. This paper was once allegedly forthcoming in: Simons, Peter (ed.), Essays on Meinong (Dettelbach: Roell Verlag) (or possibly Amsterdam: Rodopi Editions).

Only recently (ca. 1970s) has there been a renaissance in Meinong studies. Even so, his writings are often treated as curiosities (or worse) by mainstream philosophers.
