But how does it do that? The answer to this would be an explanation of the
two uses
use
of the expression. But how could this explanation reach
under the surface? It is an explanation about
signs
symbols
& it states the in which cases it these
symbols
signs
are used. But how does it characterize
the
these
cases? Can it in the end do more than distinguish two expressions? I.e. describe a game with two expressions?
     “Then is there nothing under the surface?!” But I said that I was going to distinguish two expressions, one for the ‘surface’ & one for ‘what is below the surface’ only remember that these expressions themselves correspond just to a picture, not to its usage. It is just as misleading to say that there is
just
nothing but
surface ˇ& nothing underneath it as that there is something below the surface & not that there isn't just the surface. Because once the picture we
make use of
use
the picture of the ‘surface’ it is most natural to
express with it the distinction as on & below the surface.
use it such as to express the distinction as that between something on & something below the surface.

 But // Because we naturally use
this
the
picture to express the distinction as that between ‘on the surface’ & ‘below the surface’ // But we misapply [it|the picture] if we ask whether both cases are or aren't on the surface.
