and in order that this object should have a
real effect upon it, this object must be a
subject of force, which is an individual.
Consequently, an adequate interpretant of
a graph must represent it as a sign of
an individual. How, then, can there be
a graph of a graph, considering that a
graph is a legisign, or sign which has
the mode of being of a general type,
just as any word is a general type, and
not a single individual object in a
single definite place at a single instant. The
answer is that a graph can only
have a graph for its object indirectly.
Directly, it can only refer to a graph replica.
