  Closely related to the Substitution Problem is what Moltmann (2003, p. 87) calls the Objectivization Effect, or objectivization. Substitutions in some cases seem to force a new reading for the verb, an object reading rather than a content reading. Thus, in ‘I imagine that it will snow this year,’ ‘imagine’ has the content reading (this is, by stipulation, what the content reading is!), whereas in ‘I imagine the proposition that it will snow this year,’ ‘imagine’ takes an object reading — it expresses the same relation that holds between subjects and garden variety objects such as those designated by NPs like ‘19th-century Wessex’ and ‘my college roommate’.
