Comment on Object Aggregate #161

Open GoogleCodeExporter opened 9 years ago

The following statement is incorrect:

"Object aggregate is to be treated as a close analogue of set of objects, in 
the mathematician’s sense; thus [-->] an object aggregate has no parts other 
than the objects that are its members."

A part of a member is a part of the object aggregate. It's just not another 
member. You want to say there is no part of the aggregate has a part that 
doesn't overlap a member, and that no sum of proper parts of members are 
members (even though such a sum could be part of the aggregate)
