Open peer commentary on the article “Second-Order Cybernetics as a Fundamental Revolution in Science” by Stuart A. Umpleby. Upshot: Connecting Umpleby’s article with Piaget and García’s genetic epistemology, I will argue that the revolution the former discerns is more comprehensive. Additionally, since the latter differ from cybernetic and radical traditions in their philosophical assumptions about society and its conditioning on knowledge, I will suggest that these assumptions must be considered to explain each constructivist program’s achievements and challenges.

Open peer commentary on the article “Subsystem Formation Driven by Double Contingency” by Bernd Porr & Paolo Di Prodi. Upshot: I acknowledge the value of Porr & Di Prodi’s piece for simulating Luhmann’s key process of subsystem formation and exploring how the concepts of “differentiation” and “binary code” relate to their model.
