18. If we derive geometrical propositions from a drawing or a model,
then the model has the role of a sign in a game. We use the drawing of a cube
again and again in different contexts. It is this sign that we take to be the cube in which the geometrical laws are
already laid up.
yes – the model – is a sign
it is not that geometrical laws are laid
up in the sign –
it is rather that the use of
the sign has lead to the ‘geometrical laws’
and if you are
familiar with its use –
you will most likely
be familiar with laws –
that have come to
underpin it
