Pages: 807 – 829

In [1], a new approach was suggested for finding quantum structures that might, in particular, be used in potential approaches to quantum gravity that involve non-manifold models for space and/or space-time (for example, causal sets). This involved developing a procedure for quantising a system whose configuration space--or history-theory analogue--is the set of objects in a (small) category Q. In the present paper, we show how this theory can be applied to the special case when Q is a category of sets.
