 The dispute turned, notoriously, on the status of non-existent objects. For Meinong, there are non-existent objects, they can possess properties, and true things can be said about them. For Russell, there are no non-existing objects, they cannot possess properties, and nothing true can be said about them. So, for Meinong, it is true the golden mountain is golden, because everything that is F and G is F. For Russell, it is false that the golden mountain is golden, because there is no such thing as the golden mountain to be golden.
