The thought that doing metaphysics is a fine pastime is at least in part about a certain activity. And the thought that Platonism is sensible is at least in part about a certain philosophical theory. Reflection on these platitudes brings to the fore a role we might call being an object of thought or being thought of, or perhaps some related modal notion such as being possibly thought  of.[20]
