Open peer commentary on the article “Circularity and the Micro-Macro-Difference” by Manfred Füllsack. Upshot: The target article is criticised because it conflates models of causation with causation itself. The arguments used in the target article to avoid a straightforward distinction between fine-grained measurements and the abstractions used to model them are discussed. The value of using the word “causation” to refer to atemporal models is questioned.

Open peer commentary on the article “Plasticity, Granularity and Multiple Contingency - Essentials for Conceiving an Artificial Constructivist Agent” by Manfred Füllsack. Upshot: The target article is criticised on four counts. It fails to make clear what is meant by the phrase “constructivist agent,” and whether the author is trying to define “constructivist agent” or arguing what the minimal criteria for this are (there are problems with either. It does not make clear whether weak or strong emergence is intended (there are problems with either. The arguments for a minimal level of granularity are incoherent. To summarise, the whole project has a normative flavour that seems odd given the constructivist stance it intends to argue from.
