hey. now i can't spell this to save myself... but i remember reading a bit about heccaity (or primitive thisness is easier to spell...) a few years back...
something about... leibniz has a couple of laws... one of them was
the indescernability of identity
(thoguh maybe i got the name wrong)
if a has a property that b lacks
then a cannot be b
(which is great for trying to figure whether the mind is the body...)and i think there was another
the identity of indescerbibles
(though maybe I got the name wrong)
if a and b have all the same properties
then a is band some people think the latter law falls out of the former...
but this has been disputed.i remember reading something about...
if there is a universe / world... and... (i don't think i can describe this in a neutral way...) but all that exists is two qualitatively identicle balls of iron.
they have all the same properties. including relative location. and so if the latter law is correct then there can only be one ball of iron. but surely there are two balls of iron...
and that is supposed to show the second law to be false...
and thus...
there is primitive thisness.
hmm.
hmm..what do you reckon?
i think...
so
i think so...
