The paradoxical nature of change is much richer than the orthodox “*paradox of the liar*” which switches from “true” to “false,” and from “false” to “true,” and so on and so forth in dynamic stability. The unorthodox nature of change arises when you apprehend “change” any way you wish to apprehend it, and it will yield something else, otherwise it wouldn’t be “change.” This is, I believe, its therapeutic force. -- Heinz von Foerster ⇒ The Ethical Imperative
