 Any philosophy of facts owes us an account of the form of such expressions as “the fact that Sam is sad” (Lowe 1998) and “the state of affairs that Sam is sad”. (Analogous questions arise concerning the form of “the proposition that Sam is sad”, “the property of sadness”, “the concept of sadness” etc.) Friends of facts who have written at great length about facts and given the distinct impression that they are referring to facts and predicating properties of facts have nevertheless claimed that facts or situations cannot be named (Russell, Wittgenstein; cf. Clarke 1975) or that they have no properties (Ingarden 1965). The expression “the fact that Sam is sad” looks like a definite description. What is the form of such a description? One possibility (Künne 2003: 10) is that it should be read as: the unique \(x\) such that \(x\) is a fact and \(x =\) that Sam is sad.
