How would you imagine a complex system which is not non-linear? I would say that linear = proportianal relationships; non-linear -> arbitrary functional relationships. Not even non-linear would then imply _no_ relationships - so no complex system. 2) I assume there are types of complexity (and, therefore, many - I mean really many - types) > that cannot be expressed in any formal system (beyond linearity / > non-linearity). You mean systems that can't even be modeled computationally? I would not equate non-linear systems with those one can model with diff. eq. in closed form. >Something like Gödel's theorem. ? How that?
