Author's Response: What Constructivism Does not Say

Upshot: Egner’s suggestion that a theory of observation should be developed towards a more abstract concept in order to apply it to any autopoietic system is plausible from the point of a general systems theory. However, this strategy of theorizing is not suited to solving epistemological problems in particular because such a broad concept fails to specify constructivism as a strictly observer-related philosophy.
