In this article I will suggest ways in which adding the French philosopher Gilles Deleuze to the mix can complement and extend the 4EA approach to cognitive science. In the first part of the paper, I will show how the Deleuzean tripartite ontological difference (virtual/intensive/actual) can provide an explicit ontology for dynamical systems theory. The second part will take these ontological notions and apply them to three areas of concern to the 4EA approaches: (a) the Deleuzean concept of the virtual will clarify the ontological status of perceptual capacity as sensorimotor skill; (b) the Deleuzean concept of “intensive individuation” will clarify the ontological status of the genesis of perceptually guided behavior; (c) the Deleuzean critique of confusing the actual and the virtual will enable us to intervene in the realism/idealism debate. These aspects will not be addressed sequentially but will be interwoven into an unfolding argument.

The volume presents 20 essays on the ontological, moral, and legal status of the in vitro embryo.

The continuing discussion of the species problem suffers from the lack of a coherent ontological theory as a basis for determining whether species have an ontological status. It has attempted to apply a full-fledged metaphysical theory to the species problem: the ontology of Mario Bunge. In doing so a few ontological fundamentals including system, individual, real and conceptual object, and law are briefly introduced. It is with the help of these fundamentals that an analysis of the species-as-individuals thesis is carried out, concluding that species are not individuals (things), but natural kinds, and that they have no ontological status. In contradistinction to the traditional view of natural kinds involving possible worlds metaphysics and semantics a notion of natural kind is given in terms of the state space approach and of nomological equivalence.

The paper has two parts. The first considers the debate about whether social entities should be regarded as obiects distinct from their members and concludes that we should let the answer to this question be determined by the theories that social science finds to have the most explanatory power. The second part argues that even if the theory with the most explanatory power regards social entities such as organizations as persons in their own right, we should not accord them citizenship in the moral realm. Rather we should accept moral individualism, the thesis that only individual humans can have rights and duties.The moral status of corporations and other organizations is often thought to depend on their ontological status. In particular, it is thought to depend on whether they can be said to exist as distinct entities, and especially as persons distinct from the individuals who are their members. In this article Iargue that the two questions are actually independent of each other. No matter what the ontological status of organizations, they should not be accorded citizenship in the moral realm in their own right.

In the Fifth Meditation, Descartes makes a remarkable claim about the ontological status of geometrical figures. He asserts that an object such as a triangle has a 'true and immutable nature' that does not depend on the mind, yet has being even if there are no triangles existing in the world. This statement has led many commentators to assume that Descartes is a Platonist regarding essences and in the philosophy of mathematics. One problem with this seemingly natural reading is that it contradicts the conceptualist account of universals that one finds in the Principles of Philosophy and elsewhere. In this paper, I offer a novel interpretation of the notion of a true and immutable nature which reconciles the Fifth Meditation with the conceptualism of Descartes' other work. Specifically, I argue that Descartes takes natures to be innate ideas considered in terms of their so-called 'objective being'.

Throughout his illustrious career, Roderick Chisholm was concerned with the nature of persons. On his view, persons are what he called ‘entia per se.’ They exist per se, in their own right. I too have developed an account of persons—I call it the ‘Constitution View’—an account that is different in important ways from Chisholm’s. Here, however, I want to focus on a thesis that Chisholm and I agree on: that persons have ontological significance in virtue of being persons. Although I’ll make the notion of ontological significance more precise later, the rough idea is that Fs (persons, or whatever) have ontological significance just in case a new F is a new thing and not just a change in some already-existing thing.

The philosophical problem of universals is traditionally framed as the problem about the ontological status of universals. It is often said that the ontological status of universals is a post-Aristotelian problem that was bequeathed to the Middle Ages by a famous sentence in Porphyry's Isagoge. 1 Porphyry raises but then refuses to answer three questions about the ontological status of genera and species, saying that they are too "deep" for the present investigation. 2 Although Porphyry is the first to announce the problem, it was Boethius's commentary on Porphyry, rather than the Isagoge itself, that made this sentence famous and that is therefore responsible for the problem of universals in ..
