In his famous book Laws of Form, George Spencer-Brown
tries to construct
the world from the most simple. He begins with a simple distinction, a
circle on a structureless plane for example. He does not say that this
is the only way to begin, but makes the reader simply do
it and see what is developing. In addition, he gives more handling
instructions, which reduces the most possible to the least possible.
I focus on his beginnings – the distinction – and the way how this is
interpreted by him (indeed): ”… every duality implies triplicity: what
the thing is, what it isn’t, and the boundary between
them.” By this the world is digitalized. Subsequently, he examines
extensions (“… to recross [the boundary] is not to cross [the
boundary]”) and reductions (“What a thing is and what it is not are
identical in form”). In any case, the boundary remains only boundary,
i.e. distinction.
