the conception of a possible state of affairs -
effectively a possible world - that is behind any 'should' -
is to conceive of a state of affairs - that is -
at the time of conception - unknown
it is only in the bringing about - the actualization
that such is known
and with that the 'should' of morality - disappears
what I should do - only exists as an unknown
to say - 'I should....' - 'you should....'
is to project an idea
of a particular state of affairs
which implies a world view
(the world is to be made different)
you may say - is imagined
it can only be known as an actual state of affairs
