Suppose we have the following situation:
Club A imposes no conditions on its members
Club B requires members to swear a loyalty oath,
and to swear no other oaths
Club C requires members to swear a loyalty oath,
and to swear no other oaths
The set of final clubs is well-defined, and is composed of
clubs B and C (the set of clubs which require loyalty oaths);
membership in club A neither precludes nor is precluded by
membership in clubs B or C. This doesn't help us find a
non-recursive definition of 'final club', but it does
illustrate that not all clubs are necessarily final.
