The treatment of terms in the intensional logic tradition property of certain sentences might seem strange to modern readers. The intension of a predicate, in 20th Century philosophy, includes only those properties that any competent speaker of a language would associate with that predicate. These properties are not enough to make true ordinary statements like ‘every dog in my house is asleep’. But we can make sense of the intensional view of terms by considering its origins. One of the founders of the intensional logic tradition is Leibniz, who thinks that all truths are grounded in the nature of individuals. The complete concept of an individual contains everything that is true of it. Building on this, we can see that the complete concept of a term will include enough to ground any truth about it as well.
