has no value at all. It follows that our system of
Existential Graphs is precisely an application of
the mathematics of two values. It will give you
an idea of what Pure Mathematics is to imagine
that the Existential Graphs to be described without
any allusion whatever to their interpretation, but
to be defined as symbols subject to the fundamental
rules of transformation. Namely,
1st, A graph is composed of spots with definite hooks from each
of which one heavy line extends
2nd, Any graph within an even number of cuts
can be erased and any within an odd number
of existing cuts can be inserted
3rd. Any graph can be iterated and deiterated
provided the iterated or deiterated replica is not
outside of any cut that the other is inside of.
4th. The cuts one inside the other with nothing
between except heavy lines passing from within
