Ontological pluralism is the view that there are different ways of being. Historically, ways of being are aligned with the ontological categories. This paper is about to investigate why there is such a connection, and how it should be understood. Ontological pluralism suffers from an objection, according to which ontological pluralism collapses into ontological monism, i.e., there is only one way to be. Admitting to ontological categories can save ontological pluralism from this objection if ways of being ground ontological categories. (...) -/- . (shrink)

This paper delves into the examination of metaphysical knowledge from the unique vantage point of Thomas Reid. While some philosophers, including Immanuel Kant, assert the impossibility of metaphysical knowledge based on specific epistemological and methodological principles, Reid, a proponent of direct realism, presents alternative epistemological and methodological principles that challenge the skeptics’ stance. The primary objective of this paper is to explore whether metaphysical knowledge is attainable through Reid’s perspective. In this paper, I contend that Reid’s direct realism indeed opens (...) up the possibility of metaphysics. Nevertheless, determining whether we truly possess metaphysical knowledge is far from straightforward. Instead, we rely on reliable tests to evaluate the reliability of some metaphysical beliefs.

In Spinoza’s ontology, there are only two categories of existing items: an independent entity that is one substance, and dependent entities that are infinite modes; “nothing exists external to the intellect except substances and their affections”(Proof of 1.P.4). Nevertheless, Spinoza introduces a third notion, ‘attribute’, that is defined as “what the intellect perceives of substance as constituting its essence” (1.d.4). Spinoza’s metaphysics is known for the doctrine of substance monism that indicates that only one substance exists. Spinoza, however, explicitly states (...) that “substance consisting of infinite attributes, each of which expresses eternal and infinite essence, necessarily exists.” These remarks create a perplexing puzzle regarding the ontological status of attributes in Spinoza’s philosophy. In the literature, in general, there are two opposite interpretations: the realist view (i.e., Curley (1988)) according to which attributes are real substances; and the anti-realist interpretation (i.e., Wolfson (1934)) that holds that attributes are not metaphysically real. In this paper, I provide some textual evidence from Spinoza’s works that contradicts both mentioned the realist and the anti-realist interpretations. As an alternative, I put forward a new account according to which attributes are real and objective; nevertheless, they should not be understood as distinct things in Spinoza's metaphysics. (shrink)

Pluralists believe in the occurrence of numerically distinct spatiotemporal coincident objects. They argue that there are coincident objects that share all physical and spatiotemporal properties and relations; nevertheless, they differ in terms of modal and some other profiles. Appealing to the grounding problem according to which nothing can ground the modal differences between coincident objects, monists reject the occurrence of coincident objects. In the first part of this paper, I attempt to show that the dispute between monists and pluralists cannot (...) be settled based upon the grounding problem tout court. I argue that the grounding problem or a very similar problem is a challenge for all monists and pluralists alike if they are ontologically committed to the existence of composite objects as independent entities. In the final part, adopting the Aristotelian account of essence, I propose a solution that enables pluralists to plausibly ground modal differences between coincident objects. (shrink)
