We provide an overview of the meta-ontological position known as "Quantifier Variance".

This paper defends a substance-based metaphysics for organisms against three arguments for thinking that we should replace a substantial understanding of living things with a processual one, which are offered by Dan Nicholson and John Dupré in their edited collection, Everything Flows: Towards a Processual Philosophy of Biology. Dupré and Nicholson consider three main empirical motivations for the adoption of a process ontology in biology. These motivations are alleged to stem from facts concerning metabolism; the life cycles of organisms; and (...) ecological interdependence. The paper discusses each of the three arguments in turn and concludes that none gives us any compelling reason to abandon the metaphysics of things. At best, they are arguments against a kind of caricature substance metaphysics that ought never to have been in the running in any case. Then, at the end of the paper, it is suggested that there may be more positive arguments for insisting on retaining things in our metaphysics, arguments which, perhaps ironically get their main impetus from the phenomenon of life.

I call "material continuation" the fact of one material thing or event being followed by another in time. In this article, I address the question why material continuation obtains, as it seems to do. Johanna Seibt's theory of dynamism promises to explain material continuation by reference to Aristotle's concept of energeia. I argue that her account fails to explain how one thing at one time might be followed by another at another.

Drawing from a Sellarsian realist-naturalist epistemology, we trace different levels of cognitive hierarchy procedures through which a representational system learns to update its own states and improve its ‘map-making’ capabilities from pre-conscious operations which modulate base-localization functions, to patterns of epistemic revision and integration at the conceptual and theoretical levels, producing a nomological double of its world. We show how ontological theorization becomes diachronically coordinated with and constrained by empirical science, and how the formal-quantitative kernel of scientific theories corresponds to (...) qualitative-conceptual determinations at the structural level. Following Johanna Seibt’s characterization of ontology as a theory of categorial inference, we trace the preservation of inferential semantic structure across ontological theories in relation to model languages and provide provisional indications to coordinate Seibt’s account with a convergent realist assessment of systematic modeling, defining the epistemological conditions for articulating the preservation of formal structure in theories toward a limit-point of enquiry.
