a quality in that it is a possibility posterior to
existence. [dots] Here are five dots, and the
existence of those five dots constitutes the
existence of the collection. I might put in a

constitutes the possibility of a collection of
six dots. The existence of those five dots not only
constitutes the existence of the one collection of five
dots but also the existence of five collections of
4 dots each, as well as 10 collections of 3 dots each,
10 collections of 2 dots each, 5 collections of 1 dot each,
and 1 collection nothing; and these 32 collections
constitute one collection of collections. Or we may
say there is a collection of six collections each of
which latter collections is a collection of equal collections
of dots.
