 A third theory says that the contents of experience are composed of modes of presentation of objects and properties, rather than objects and properties themselves. The key feature of modes of presentation, on this view, is that a single object or property can have multiple modes of presentation. A Fregean content will be true only if the object presented by a mode of presentation in the content has the property (or properties) presented by a mode of presentation in the content. (See Chalmers 2004).
