 Existence-conditions: A thought is a complex whose constituents are modes of presentation that purport to represent objects. Standard accounts of modes of presentation allow for the existence of modes of presentation that are empty. Hence, the existence of a thought does not depend on the existence of the objects it purports to represent. For example, the thought that Pegasus is a horse exists, although there is no such horse (for defense and elaboration see Sainsbury 2005: 86–9). This is different for states of affairs. If a state of affairs is a complex that contains objects and properties as constituents, it cannot exist if its constituents don’t exist. So while it is true that Pegasus does not exist, there is no such state of affairs. This is unproblematic for we have not been given any reason to think that such a state of affairs obtains or does not obtain. For the same reason states of affairs that contain contingently existing objects are themselves contingent existents.
