the plot type is a sign type, but is it a sign? Or are only the tokens signs, because only they are perceived? Like a book that is read. And is the book only a sign when it is being read, because only then it is interpreted, and when it is closed, it sort of sleeps and is not a sign?
And is a complex system, like a person or a society, a sign too? If so, maybe a systems theory is not necessary, but a box-in-box-theory of signs, like a person who reads a book is a sign which interprets another sign. And when nothing is happening, the book is closed and the person asleep, there are no signs, but sign tokens and sign types.
So maybe it would be possible to translate all systems theory terms into Peircean "sign-" terms, and not use the term "system" at all?
