Notoriously, in Theory of Knowledge Russell postulates logical forms as objects. Several authors have examined Russell's reification of forms from the point of view of their role in the multiple relation theory of judgment. But logical forms are also supposed to play a second role: they are the objects of logical knowledge. I argue that a proper understanding of logical forms can only be had by paying attention to Russell's theory of logical knowledge and his understanding of logic. If we do this we find that logical forms have rather strange properties, but that these properties are put in place by Russell to accommodate his views on logic and epistemology.
