In 1972 Gilbert Ryle published a eulogy to Meinong's theory of objects:
Let us frankly concede that Geganstandstheorie itself is dead, buried and not going to be resurrected. Nobody is going to argue again that, for example, “there are objects concerning which it is the case that there are no such objects.”
Since that time, the firm of Routley, Routley, Chisholm and Parsons has vigoruously defended Meinong's theory. Are they advocates for a dead client?
