The picture consists in the fact that its elements are combined with one another in a definite way.
The picture is a fact.
That the elements of the picture are combined with one another in a definite way, represents that the things are so combined with one another.
This connection of the elements of the picture is called its structure, and the possibility of this structure is called the form of representation of the picture.
The form of representation is the possibility that the things are combined with one another as are the elements of the picture.
Thus the picture is linked with reality; it reaches up to it.
It is like a scale applied to reality.
