 However, even the covert operator theory might be contested, on the grounds that within its scope we are still unintelligibly predicating ‘lived on Mt. Olympus’ of an abstract object. Simply prefixing ‘according to the myth’ to the unintelligible cannot render it intelligible. But there is the evident fact that (25) is both intelligible and true. So either prefixing ‘according to the myth’ can render the unintelligible intelligible, or what is going on in the embedded sentence is not to be construed as standard predication. For further discussion of these matters, see, for example, van Inwagen 1977, Parsons 1980, Zalta 1988, Thomasson 1998, and Salmon 2002.
