There is renewed interest in questions of ontology in various fields, as there has been in biosemiotics. But for umwelt theory, ontology needs to be approached in particular ways, in order to avoid it from being yet another “philosophy of access”, part and parcel of the epistemology-ontology dyad, where “ontology” is the leftover of epistemology, or any sort of subjective constitution of things. The article engages in philosophical considerations about what kinds of assumptions and preliminary considerations should be made for (...) a semiosic ontology that was multiple, relational, and irreducible, with the principle goal being to engage with some terminological issues at the meeting point of ontology and umwelt theory. Ontography is proposed as a name for a low-key descriptive engagement with non-human umwelts considered as “worldings”, and maieutics as a particular attitude, or ethos, for the practical situation of direct inaccessibility of nonhuman umwelts. Parallels are drawn with the ontological turn in anthropology, which has also successfully engaged with alterity. A comparative study of umwelts should consider the ontological self-determination of the nonhuman other. (shrink)
