Formal ontology as a main branch of metaphysics investigates categories of being. In the formal ontological approach to metaphysics, these ontological categories are analysed by ontological forms. This analysis, which we illustrate by some category systems, provides a tool to assess the clarity, exactness and intelligibility of different category systems or formal ontologies. We discuss critically different accounts of ontological form in the literature. Of ontological form, we propose a character- neutral relational account. In this metatheory, ontological forms of entities (...) are their standings in internal relations whose holding is neutral on the character of their relata. These relations are “formal ontological relations”. Entities belong to ontological categories because they stand in the same formal ontological relations. We hold a nominalist relationalism about ontological categories and forms. We conclude by showing that our metatheory is useful for understanding categorial fundamentality/non- fundamentality, different formal ontologies, and for unifying metaphysical questions. (shrink)

This article contends that the central principle of modern philosophy is obscured by a side-debate between two opposed camps that are united in accepting a deeper flawed premise. Consider the powerful critiques of Kantian philosophy offered by Quentin Meillassoux and Bruno Latour, respectively. These two thinkers criticize Kant for opposite reasons: Meillassoux because Kant collapses thought and world into a permanent “correlate” without isolated terms, and Latour because Kant tries to purify thought and world from each other rather than realizing (...) that they are always combined in “hybrid” form. What both critiques tacitly accept is the notion that “thought” and “world” are the two major poles of the universe. I claim that this stems from the post-Cartesian assumption that thought and world are the two basic kinds of things that exist. The name “onto-taxonomy” is introduced for this view. (shrink)
