It depends how you interpret it. John interpreted in two
different ways in his example.
With one interpretation, saying "mambersip in club A is
compatible with membership in any other club" and
"membership in club B precludes membership in any other
club" are contradictory. With the other interpretation
they are not.
>Membership in A precludes membership in B certainly does imply that
>membership in B precludes membership in A.
Certainly in practice. But a rule of club A precluding
its members from being members of club B does not entail
that there be a rule in club B precluding its members
from being members of club A. Even if in practice they
couldn't be members of A because of A's rules.
What is not clear to me is whether the "definition"
talks about practical or normative preclusion.
