Dear Thuchan, American philosopher Nelson Goodman caused
much disturbance by questioning ''law like'' character of some
predicates. Say ''all emeralds are green''. Law like means that all
instances observed till T1 were green obviously confirming the
''green property'' of emeralds. But what about all emeralds being
green at T1 and then observed at T2 to be ''blue''? We are used to
use the Greek (metalic) way of describing people. Say ''Henry is honest like gold'' and Peter ''strong like iron''. But when Henry robbed a bank and seduced the wife of his friend we feel somehow ashemed and state: ''Who would believe such a thing about Henry? This imply ''nobody would believe such a thing and that is why I also made this mistake''.
If I understand your argument well you meant all TT's at time T1
but deed not meant TT's there after ? This would imply that
qualification ''the best'' does apply for the time T1 but not thereafter.
