16. What does it mean to say that the “is” in “The rose is red” has a
different meaning from the “is” in “twice two is four”? Here we have one word
but as it were different meaning-bodies
with a single end surface: different possibilities of constructing sentences.
The comparison of the glass cubes. The rule for the arrangement of the red
sides contains possibilities, i.e. the geometry of the cube. The cube can also
serve as a notation for the rule if it belongs to a system of propositions.
one word with different-meaning bodies – different applications –
the different applications
emerge from practice –
we can try and explain such in terms of so called rules –
‘explanations’ of practice
rules that contain possibilities?
no explanation of practice is every complete
any ‘system of rules’ – is epistemologically unstable –
hence possibility
and the making of a rule or a rule for a rule –
is the result of what?
observation – experience – imagination – inspiration?
the logical point is that a rule underwrites
practice –
basically it restates accepted
practice
and the authority of a rule?
any so called ‘authority’ not logical –
it is rhetorical
logically speaking a rule is nothing more than a proposal –
no different to any other proposition –
open to question – open doubt –
uncertain
