     I wish to make clear that I admit to the possibility of higher
realms of wisdom that logic may not apply to, that IS and IS NOT can
not describe.
     What I take extreme exception to is the pretense to wisdom by
couching propositions in logical terms, IS statements, to give them
the 'credence' of logic, while covertly eschewing logic and failing to
meet the demands of consistency that logic demands.

     The definitions of IS and IS NOT are very clear and are not to be
subverted to the causes of sophistry.
     It's a matter of professional ethics and common sense.
