In this article, we advocate the use of “epistemic” ontologies, i.e., systems of categories representing our knowledge of the world, rather than the world directly. We first expose a metaphysical framework based on a dual mental and physical realism, which underpins the development of these epistemic ontologies. To this end, we refer to the theories of intentionality and representation established within the school of Franz Brentano at the turn of the 20th century and choose to rehabilitate the notion of a (...) ‘representation object’, as theorized by Kasimir Twardowski. We therefore propose that the categories of epistemic ontologies correspond to ‘general representation objects’. Secondly, we apply these proposals to the treatment of technical artefacts, material qualities of objects and events (notably as a continuation of our previous work on events). This leads us to sketch out a foundational epistemic ontology. (shrink)

Hylomorphists claim that substances—human beings, oak trees, chemical compounds—are compounds of matter and form. If a house is a substance, then its matter would be some bricks and timbers and its form the structure those bricks and timbers take on. While hylomorphism is traditionally presented as a theory of change, it only treats the coming-to-be and passing-away of matter-form compounds. But many hylomorphists understand forms to be entities in their own right, as parts or constituents of substances. So, a neglected (...) question arises: how, when, and from where do forms come to be? I take up the view of one prominent and representative hylomorphist, Kathrin Koslicki, and argue that she cannot answer these questions satisfactorily. I close with a proposal for an account of the generation of forms based on machinery many hylomorphists already accept, namely, causal powers, that points to a deflationary metaphysics of form.
