I examine a major objection to the mechanistic view of concrete computation, stemming from an apparent tension between the abstract nature of computational explanation and the tenets of the mechanistic framework: while computational explanation is medium-independent, the mechanistic framework insists on the importance of providing some degree of structural detail about the systems target of the explanation. I show that a common reply to the objection, i.e. that mechanistic explanation of computational systems involves only weak structural constraints, is not enough (...) to save the standard mechanistic view of computation—it trivialises the appeal to mechanism, and thus makes the account collapse into a purely functional view. I claim, however, that the objection can be put to rest once the account is appropriately amended: computational individuation is indeed functional, while mechanistic explanation plays a role in accounting for computational implementation. Since individuation and implementation are crucial elements in a satisfying account of computation in physical systems, mechanism keeps its central importance in the theory of concrete computation. Finally, I argue that my version of the mechanistic view helps to provide a convincing reply to a powerful objection against non-semantic theories of concrete computation: the argument from the multiplicity of computations.

For many causal endeavors, such as measuring, predicting, and explaining, individuating causal systems plays a crucial role. In this chapter, we focus on the individuation of a specific type of causal systems, what we call cross-cutting systems. These are systems that lack natural boundaries and that are not restricted to the spatiotemporal region of the individuals to which they belong. Based on examples taken from cognitive science and behavioral ecology, we explore how scientists individuate such cross-cutting causal systems.

The ‘received view’ about computation is that all computations must involve representational content. Egan and Piccinini argue against the received view. In this paper, I focus on Egan’s arguments, claiming that they fall short of establishing that computations do not involve representational content. I provide positive arguments explaining why computation has to involve representational content, and how that representational content may be of any type. I also argue that there is no need for computational psychology to be individualistic. Finally, I (...) draw out a number of consequences for computational individuation, proposing necessary conditions on computational identity and necessary and sufficient conditions on computational I/O equivalence of physical systems.Keywords: Computation; Representation; Computational identity; Explanation; Narrow content; Physical computation.

In this article, I challenge the dominant view of the importance of the debate over action-individuation. On the dominant view, it is held that the conclusions we reach about action-individuation make little or no difference for other debates in the philosophy of action, much less in other areas of philosophy. As a means of showing that the dominant view is mistaken, I consider the implications of accepting a given theory of action-individuation for thinking about doxastic agency. In (...) particular, I am interested in the implications for thinking about the variety of evaluative control we can exercise over the formation of our doxastic attitudes. I show that our assumptions about how to individuate actions matters for how we think about doxastic agency and, hence, the conclusions we reach about action-individuation are of greater significance than some have thought.

Is the mathematical function being computed by a given physical system determined by the system’s dynamics? This question is at the heart of the indeterminacy of computation phenomenon (Fresco et al. [unpublished]). A paradigmatic example is a conventional electrical AND-gate that is often said to compute conjunction, but it can just as well be used to compute disjunction. Despite the pervasiveness of this phenomenon in physical computational systems, it has been discussed in the philosophical literature only indirectly, mostly with reference (...) to the debate over realism about physical computation and computationalism. A welcome exception is Dewhurst’s ([2018]) recent analysis of computational individuation under the mechanistic framework. He rejects the idea of appealing to semantic properties for determining the computational identity of a physical system. But Dewhurst seems to be too quick to pay the price of giving up the notion of computational equivalence. We aim to show that the mechanist need not pay this price. The mechanistic framework can, in principle, preserve the idea of computational equivalence even between two different enough kinds of physical systems, say, electrical and hydraulic ones. (shrink)

In this interview, Anne Fagot-Largeault discusses with Thierry Bardini her recollections of the life and work of French philosopher Gilbert Simondon (1924–1989). The discussion covers Simondon’s theory of individuation and considers its influences on contemporary thinkers such as Gilles Deleuze and François Laruelle. Fagot-Largeault situates Simondon’s thinking within the broader context of 20th-century biological research and the development of life sciences. Informed by her personal association and experiences working with Simondon, her reminiscences shed light on the unique character of (...) Simondon as a person and as a thinker. (shrink)

This article searches for a way of theorizing the interconnectedness of processes of individuation, relationality and affect, with the aim of clearing the ground for an approach that establishes the basis of this interconnectedness by reference to mechanisms common to all living things. It establishes a number of shifts that enable us to think the categories and concepts like the individual, the subject, the group, the threshold, relationality, co-implication and so on according to a fundamental decentring, finally breaking with (...) both subject-centredness and its privilege of the individual as model or starting point; the same epistemological shift implies the rejection of the anthropocentric divide between humans and animals, while avoiding species of sociobiologism, pre-formationism, geneticism and other monocausal paradigms. What the new problematic of life enjoins us to rethink are the standpoint of singularity rather than that of the individual, coupled to the standpoint of relationality as a principle enabling us to think the self—other, human—animal, nature—culture and human—world in terms of compossibility and complex becoming. This view about the co-constitution of all life has major implications regarding responsibility for the other and responsibility for the world, grounded in the standpoint of the temporality and historicity of being as existential condition circumscribing the relation to the other. This shift at the level of ontology is explored via an engagement with the work of Simondon and his conceptual apparatus, particularly ideas of psychic and collective individuation, the pre-and transindividual, the associated milieu; this perspective is re-articulated by way of the work of Merleau-Ponty, Haraway’s notion of ‘companion species’, Ettinger’s concept of the ‘I—other plurality’, and cognate concepts that point to a new terrain for theorizing affect.

I argue against a view of the individuation of actions endorsed most notably by Hornsby and Davidson. This is the view that in, for example, Anscombe’s case of the pumping man, we have a single action which can be described, variously, as a pumping, a poisoning and so on. I argue that, even in the area of the standard arguments against this view, such as that based on the logic of ‘by’ and the argument from temporal dimensions, the case (...) against the Davidson‐Hornsby view has not been made as strong as it ought to have been. I show how those standard arguments can be strengthened; and I argue that the principal considerations adduced in support of the view do not in fact lend it the support that they have been widely thought to lend it. I conclude that the view should be rejected. (shrink)

Ontological questions in biology have typically focused on the nature of species: what are species; how are they identified and individuated? There is an analogous, but much neglected concern: what are characters; how are they identified and individuated? Character individuation is significant because biological systematics relies on a parsimony principle to determine phylogeny and classify taxa, and the parsimony principle is usually interpreted to favor the phylogenetic hypothesis that requires the fewest changes in characters. But no character individuation (...) principle identified so far is adequate. For biological systematics we need a better way of conceiving characters. (shrink)

In the pure powers ontology (PPO), basic physical properties have wholly dispositional essences. PPO has clear advantages over categoricalist ontologies, which suffer from familiar epistemological and metaphysical problems. However, opponents argue that because it contains no qualitative properties, PPO lacks the resources to individuate powers, and generates a regress. The challenge for those who take such arguments seriously is to introduce qualitative properties without reintroducing the problems that PPO was meant to solve. In this paper, I distinguish the core claim (...) of PPO: (i) basic physical properties have dispositional essences, from a hitherto unnoticed assumption: (ii) the dispositional essences of basic physical properties exclusively involve type-causal relations to other basic physical properties. I reject (ii), making room for a structuralist ontology in which all basic physical properties are pure powers, individuated by their places in a causal structure that includes not only other powers, but also physically realized qualitative properties such as shapes, patterns and structures. Such qualities individuate pure powers in the way that non-mental input and output properties individuate realized mental properties in functionalist theories of mind, except that here it is basic physical powers that are individuated by relations to realized non-powers. I distinguish one Platonic and two Aristotelian version of this theory, and argue that the Aristotelian versions require that grounding is not always a relative fundamentality relation, because the powers ground the qualities that individuate them. By considering ontic structural realism, I argue that symmetric grounding is the best way to make sense of relational individuation in structuralist ontologies, and is therefore no additional commitment of the one proposed here.

The nature of creative engagement with computers and software presents a number of challenges to 4E cognition and requires the development of analytical frameworks that can encompass cognitive processes as they extend across material and informational realms. Here I argue that an enactive view of mind allows for better understanding of digital practice by advancing a dynamic, transactional, and affective framework for the analysis of computational design. This enactive framework is in part developed through the Material Engagement Theory put forward (...) by Lambros Malafouris, in part from the phenomenologically inspired philosophy of Bernard Stiegler. Both advance temporality, technics and technique as key to understanding human creative imagination and their work can support each other in different ways; Stiegler allows for a theorisation of digital tools largely missing from the cognitive archaeology of Malafouris, whilst Malafouris provides a cognitive theory to further develop key ideas in Stiegler’s philosophy. Bringing their work together through Gilbert Simondon’s theory of individuation, I develop the concept of enactive individuation and apply this to the analysis of a case of robotic design and fabrication from my fieldwork with digital architects and engineers. This case allows for further exploration of how enactivism might productively be extended into the digital realm by underscoring the explorative engagement at heart of even highly systematic work with computers and software.

This dissertation addresses the problem of trans-world identity in possible worlds semantics, and argues that essentialism does not provide a satisfactory solution to it. If one takes possible worlds semantics seriously as a viable elucidation of the logic of the metaphysical modalities, one must also take a realistic stance toward possible worlds. But then, contrary to Kripke, Plantinga, Van Inwagen, and others, there is a problem with trans-world identity; the real problem being, not the problem of identifying individuals across possible (...) worlds, but rather the problem of the theoretical basis for these identifications. Possible worlds semantics presupposes a substantive theory of what constitutes the cross-world continuation or persistence of individuals. Standard formulations of these semantics nevertheless fail to articulate such a theory. Therefore cross-world identifications become inherently problematic. All available solutions to this problem either presuppose non-trivial essentialism or are incoherent. Non-trivial essentialism is the view that there are certain non-identity properties which a given individual has in every world in which it exists but which other possible individuals fail to have in some of the worlds in which they exist. ;But the question of the coherence of essentialism itself is intimately connected with one's views concerning the nature and existence of properties. Three Cantorian paradoxes are adduced, one against individuative essentialism, one against non-trivial essentialism, and one against properties in general. The paradoxes against properties in general and non-trivial essentialism can be avoided only if one eschews a Quine/Goodman view of property existence---the view that any extensionally well-defined class answers to a property---and makes some kind of distinction between natural and artificial properties. Nevertheless such an eschewal does not avoid the paradox of individuative essentialism. Thus essentialism cannot provide a completely adequate theory of trans-world individuation. For although it provides the necessary conditions for the identity of individuals across possible worlds, it does not allow us to identify these individuals on this basis alone. This conclusion precludes actualist solutions to the problem of the individuation of possibilia which quantify over individual essences. (shrink)

This essay focuses on a little-understood phase of Franco Moretti’s work that spans 1976 to 1986. My aim is to shed light on Moretti’s cultural background as it was formed in that period and to account for the transition from the Trotskyist, politically-militant stance of his first book, Literature and Ideologies in England in the 1930s, to the idiosyncratic, seemingly disengaged character of Signs Taken for Wonders and The Way of the World. Adorno’s concept of ‘unrestrained individuation’ plays a (...) crucial role in the argument. Following a personal political crisis, Moretti opted to enact a form of critical individuation, encoding the explicit social antagonism of the earlier years within a highly personal style and a new theoretical eclecticism. In this way, by disguising it as an alluring form of individualism, Moretti managed to smuggle an antagonistic critical discourse into an increasingly neoliberal world that would soon prove hostile toward it.

Individuation and organization in complex living multi-level ecosystem occurs as dynamical processes from early ontogeny. The notion of living “holon” displaying dynamic self-assertion and integration is used here to explain the ecosystems dynamic processes. The update of the living holon state according to the continuous change of the dynamic system allows for its viability. This is interpreted as adaptation, selection and organization by the human that observes the system a posteriori from its level. Our model concerns the complex dynamics (...) of the adaptive immune system, integrating holon-lymphocytes that collectively preserve the identity and integrity of the organism. Each lymphocyte individualizes as a dynamic holon-lymphocyte, with somatic gene individuation leading to an individual, singular antigen immunoreceptor type, promoting the self-assertion. In turn, the “Immunoception” allows for perception of the environmental antigenic context, thus integration of the holon in its environment. The self-assertion/integration of holon-lymphocyte starts from fetal stages and is influenced by mother Lamarckian acquired historicity transmissions, a requisite for the integrity of the holobiont-organism. We propose a dynamic model of the perception by holon-lymphocyte, and at the supra-clonal level of the immune system functions that sustain the identity and integrity of the holon-holobiont organism.

In _Always More Than One_, the philosopher, visual artist, and dancer Erin Manning explores the concept of the "more than human" in the context of movement, perception, and experience. Working from Whitehead's process philosophy and Simondon's theory of individuation, she extends the concepts of movement and relation developed in her earlier work toward the notion of "choreographic thinking." Here, she uses choreographic thinking to explore a mode of perception prior to the settling of experience into established categories. Manning connects (...) this to the concept of "autistic perception," described by autistics as the awareness of a relational field prior to the so-called neurotypical tendency to "chunk" experience into predetermined subjects and objects. Autistics explain that, rather than immediately distinguishing objects—such as chairs and tables and humans—from one another on entering a given environment, they experience the environment as gradually taking form. Manning maintains that this mode of awareness underlies all perception. What we perceive is never first a subject or an object, but an ecology. From this vantage point, she proposes that we consider an ecological politics where movement and relation take precedence over predefined categories, such as the neurotypical and the neurodiverse, or the human and the nonhuman. What would it mean to embrace an ecological politics of collective individuation? (shrink)

The pressure to individuate propositions more finely than intensionally—that is, hyper-intensionally—has two distinct sources. One source is the philosophy of mind: one can believe a proposition without believing an intensionally equivalent proposition. The second source is metaphysics: there are intensionally equivalent propositions, such that one proposition is true in virtue of the other but not vice versa. I focus on what our theory of propositions should look like when it's guided by metaphysical concerns about what is true in virtue of (...) what. In this paper I articulate and defend a metaphysical theory of the individuation of propositions, according to which two propositions are identical just in case they occupy the same nodes in a network of invirtuation relations. Invirtuation is here taken to be a primitive relation of metaphysical explanation exemplified by propositions that, in conjunction with truth, defines the notion of true in virtue of. After formulating the theory, I compare it with a view.. (shrink)

Assurant que « nous voyons toutes choses en Dieu », autrement dit par des idées universelles et infinies, la philosophie de Malebranche se doit d'affronter le problème de la connaissance des choses singulières, seules véritablement existantes. Après avoir montré que sa pensée échoue à fonder un authentique principe d'individuation physique des corps, nous tentons de mettre en évidence une difficulté identique à théoriser une véritable connaissance des êtres matériels. Ce déplacement de la question nous semble légitime dans la mesure (...) où les choses étendues ne sont accessibles qu'à partir de l'étendue intelligible et des sentiments qu'elle produit. Par là, nous souhaitons manifester l'inaptitude, peut-être irrémédiable, d'une métaphysique fondée sur la représentation à se saisir pleinement des singularités. Malebranche tells us that we see everything in Gods infinit and universal Ideas. In so doing, Malebranche seems unable to describe real knowledge of material singularities; more, it's quite difficult to discover a true principle of individuation in the physical treatment of matter. After all, the metaphysical background of the representative knowledge makes improbable a correct description, a philosophical experience of singularities. (shrink)

Against mathematical platonism, it is sometimes objected that mathematical objects are mysterious. One possible elaboration of this objection is that the individuation of mathematical objects cannot be adequately explained. This suggests that facts about the numerical identity and distinctness of mathematical objects require an explanation, but that their supposed nature precludes us from providing one. In this paper, we evaluate this nominalist objection by exploring three ways in which mathematical objects may be individuated: by the intrinsic properties they possess, (...) by the relations they stand in, and by their underlying ‘substance’. We argue that only the third mode of individuation raises metaphysical problems that could substantiate the claim that mathematical objects are somehow mysterious. Since the platonist is under no obligation to accept this thesis over the alternatives, we conclude that, at least as far as individuation is concerned, the nominalist objection has no bite.

Aquinas has much to say about individuation over the course of his career. Although certain aspects of his views appear to undergo development, there is one aspect that remains constant throughout—namely, his commitment to assigning both prime matter and quantity an essential role in the individuation of substances. This paper examines the vexed issue of how either prime matter or quantity, as Aquinas understands them, could have any role to play in this context. In the course of doing (...) so, the author attempts to put to rest a number of longstanding worries about the coherence of Aquinas’s views about individuation, as well as to draw out some of his broader commitments in metaphysics and natural philosophy that have yet to be fully appreciated.

The distinctions among facts, propositions, and events are supported by linguistic analyses segregating factive, propositional, and eventive predicates. The concepts of fact, proposition, and event may be basic categories of human understanding, as well as being ontologically significant. FPE theory was developed in part to reject the identification of facts with true propositions. The degree of ‘fineness’ of individuations within each category results from how closely event-, fact-, or proposition-individuation mirrors linguistic semantic structure. Event structure is not reflected in (...) many event phrases. Fact- and proposition-structure typically does reflect semantic structures of factive and propositional clauses. The relevant properties for event individuation are all expressible by eventive predicates. Fact and proposition individuation is not as straightforward, because so many factives and propositionals do not express properties relevant to the Leibnizian principle. The intractability of proposition individuation may be overcome through an explanation of fact cognition. (shrink)

Accounts of act individuation have attempted to capture peoples’ pre-theoretic intuitions. Donald Davidson has argued that a multitude of action descriptions designate only one act, while Alvin Goldman has averred that each action description refers to a distinct act. Following on recent empirical studies, I subject these accounts of act individuation to experimentation. The data indicate that people distinguish between actions differently depending upon the moral valence of the outcomes. Thus, the assumption that a single account of act (...) individuation applies invariantly seems mistaken. (shrink)

This paper aims to defend the use of the notion of experimental individuation, which has recently been developed by Ruey-Lin Chen, as a criterion for the reality of theoretical entities. In short, when scientists experimentally individuate an entity, a realist conclusion about that entity is warranted. We embed this claim regarding experimental individuation within a framework that allows for other criteria of reality. And we understand so-called retail arguments regarding the reality of a particular theoretical entity as arguments (...) that concern choosing an appropriate criterion of reality for that entity and determining whether the relevant first-order scientific evidence satisfies that criterion. We argue that such retail arguments are philosophical because defending criteria of reality, and showing that they are or are not satisfied in particular cases, involves work that is distinctively philosophical. And we illustrate this philosophical work by applying our criterion of experimental individuation to three historical cases: Davy’s potassium, Lavoisier’s muriatic radical, and Thomson’s electrified particles.

In the 21st century, Carl Gustav Jung (1875-1961) remains one of the key figures in the field of analytical psychology - and Psychological Types, or The Psychology of Individuation, published in 1921, is one of his most influential works. It was written during the decade after the publication of Psychology of the Unconscious (1912), which effectively ended his friendship and collaboration with Sigmund Freud. Whereas the earlier work had clearly marked Jung's psychoanalytical divergence from Freud it is the Psychology (...) of Types that fully clarifies and presents the nature, quality and characteristics of his analytical psychology. The work, which was in part a consequence of his need to reconcile the competing theories of Freud, whom he regarded as extraverted, and Alfred Adler, whom he saw as introverted, develops his concept of descriptive categories for understanding the human mind in terms of the two essential attitude types: introversion and extraversion. These basic attitudes operate in tandem with four principal interacting functions of consciousness which Jung identifies as sensation and intuition, which are functions of perception, and thinking and feeling, which are functions of judgment. The eight resulting psychological types are then explored, described, identified, characterised and explained in considerable detail, with a soaring range of examples drawn from the whole of human history, culture and experience. In his efforts to explore and illuminate the nature of the unconscious mind and indeed the collective unconscious, he investigates the problems posed by the differing psychological types and how these have manifested from classical and medieval times to the 20th century. His observations range from Aristotle, Socrates and Plato to Tertullian and Origen, and from Abélard and Master Eckhart to Martin Luther and the problem of transubstantiation. Jung takes the listener on an odyssey of human thinking. He considers the problem of types in the works of Schiller and Goethe, and Spitteler and his treatment of the Prometheus myth. He contrasts idealism and realism, the Apollonian and the Dionysian in Nietzsche, and explores a host of philosophical and religious sources from the Bible to Taoism to Brahminism. He considers the nature of the reconciling symbol in Spitteler before analysing the nature of types in modern philosophy, aesthetics and biography, giving detailed consideration to William James' characteristic pairs of opposites and Furneaux Jordan's 'character sketch of the emotional types'. Jung goes on to fully identify and describe the characteristic differences between the extraverted and introverted types and provides an extensive chapter on definitions to fully clarify the meaning of the language he employs and make his meaning more accessible. Authoritatively read by Martyn Swain for Ukemi Audiobooks, Psychological Types is an inexhaustible treasure chest of ideas and creative inspiration worth listening to time and time again. (shrink)

How many senses do humans possess? Five external senses, as most cultures have it—sight, hearing, touch, smell, and taste? Should proprioception, kinaesthesia, thirst, and pain be included, under the rubric bodily sense? What about the perception of time and the sense of number? Such questions reduce to two. 1. How do we distinguish a sense from other sorts of information-receiving faculties? 2. By what principle do we distinguish the senses? Aristotle discussed these questions in the De Anima. H. P. Grice (...) revived them in 1967. More recently, they have taken on fresh interest as a result of a collection of essays edited by Fiona Macpherson. This entry reviews some approaches to these questions and advances some new ideas for the reader’s consideration. It proposes that the senses constitute an integrated learning system, membership in which answers question 1. It also proposes that the modalities can be distinguished from one another in two ways, by the means of information pick-up and by the kinds of activity that a perceiver undertakes to make use of them.

In chapter IX of the Principles, Anne Conway claims that her metaphysics is diametrically opposed to those of Descartes and Spinoza. Scholars have analyzed her rejection of Cartesianism, but not her critique of Spinoza. This paper proposes that two central points of Conway’s metaphysics can be understood as direct responses to Spinoza: (1) the relation between God, Christ, and the creatures in the tripartite division of being, and (2) the individuation of beings in the lowest species. I will argue (...) that Conway, in criticizing Spinoza’s identification between God and nature, defends a paradoxical monism, and that her concept of individuation is a reductio ad absurdum of Spinoza’s criterion of identity in the individuation of finite modes.

It is common to explain agreement and disagreement in terms of relations among mental states. The main purpose of the present discussion is to present an alternative way of thinking about the relationship between mental states and agreement and disagreement. The idea is to connect agreement and disagreement with the individuation of mental states. More specifically, for at least some mental states, standing in the same relations of agreement and disagreement is both necessary and sufficient for identity. This provides (...) us with a framework for discussing issues related to agreement and disagreement. It is for instance well-known that de se beliefs raise questions about agreement and disagreement. The present framework allows us to discuss such beliefs while relying on assumptions that are interestingly different from the standard assumptions in the literature. While most of the discussion focuses on beliefs, there are other mental states, such as desires, that can seemingly also stand in relations of agreement and disagreement. This raises questions about how far the framework can be extended. (shrink)

Alan Sidelle's Necessity, Essence, and Individuation is a sustained defense of empiricism—or, more generally, conventionalism—against recent attacks by realists. Sidelle focuses his attention on necessity a posteriori, a kind of necessity which contemporary realists have taken to support realism over empiricism. Turning the tables against the realists, Sidelle argues that if there are in fact truths necessary a posteriori, it is not realism, but rather empiricism which provides the best explanation for them.

This contributed volume aims to reconsider the concept of individuation, clarifying its articulation with respect to contemporary problems in perceptual, neural, developmental, semiotic and social morphogenesis. The authors approach the ontogenetical issue by taking into account the morphogenetical process, involving the concept of individuation proposed by Gilbert Simondon and Gilles Deleuze. The target audience primarily comprises experts in the field but the book may also be beneficial for graduate students. The challenge of the genesis and constitution of "units" (...) has always been at the center of philosophical and scientific research. This ontogenetical issue is common to every discipline but it is articulated in different ways: in phenomenology of perception the constitution of perceptual units is at the base of gestalt field theories, in theoretical neuroscience synchronized neural assemblies are considered as correlates of conscious processes, in developmental embryogenesis the constitution of organs is the principle outcome of morphodynamic evolution while in social morphogenesis the constitution of coherent units is common to segmentary, gerarchic and functional differentiation.

Spinoza developed a highly interesting metaphysical theory of nature and individuality. In this paper, I endeavor to bring forward some ideas on how Spinozistic views on extended substance, physical world, and individuality can be approached using the concept of power as the basis of interpretation. Jonathan Bennett's ‘field metaphysical’ interpretation of Spinoza's doctrine of one extended substance has generated much discussion, and forms the other starting point of my paper. I believe that the field metaphysical interpretation enables one to deal (...) with the central questions concerning physical individuation — individuality and the persistence of individual being — in a rather novel way. My main question is this: what follows if physical individuals are seen as parts of a unified field of extended power? (shrink)

A tropel is a particular property: the redness of a rose, the roundness of the moon. It is generally supposed that tropes are individuated by primitive quantity: this redness, that roundness. I argme that the trope theorist is far better served by individuating tropes by spatiotemporal relation: here redness, there roundness. In short, tropes are not this-suches but here-suches.

One important part of Aquinas’s theory of the nature of corruptible corporeal substances is his account of the individuation of such entities. In this paper, I examine an aspect of Aquinas’s account of individuation that has not received as much attention as some others, namely, how Aquinas applies his account of individuation specifically to cases involving non-living corporeal substances. I first offer an interpretation of a key passage in Aquinas’s corpus where he explains his theory of (...) class='Hi'>individuation. Second, I examine a text where Aquinas applies his account of individuation to a case involving non-living substances. Finally, I raise a possible objection to what Aquinas says about the individuation of non-living substances and in answering the objection suggest that Aquinas holds the view that non-living substances enjoy a less perfect mode of individuality when compared to living substances.

Two physical approaches—as distinct, under the classification of Mittelstaedt, from formal approaches—to the problem of individuation of quantum objects are considered, one formulated in spatiotemporal terms and one in quantum mechanical terms. The spatiotemporal approach itself has two forms: one attributed to Einstein and based on the ontology of space-time points, and the other proposed by Howard and based on intersections of world lines. The quantum mechanical approach is also provided here in two forms, one based on interference and (...) another based on a new Quantum Principle of Individuation (QPI). It is argued that the space-time approach to individuation fails and that the quantum approach offers several advantages over it, including consistency with Leibniz’s Principle of Identity of Indiscernibles.

Starting from an anecdote reported by Ernst Mach in the Analysis of Sensations, the author shows how the distinction between intentionality de re and intentionality de se can contribute to solving the individuation problem, at least for those individuals who are capable of self-referentiality. Intentionality is expressed linguistically in the form of the oratio obliqua, in the context of which the subordinate can be false even when the whole is true. The analysis of the conditions of falsity of the (...) subordinate tells us that this can be false either because the predicate does not fit to the subject or by a failure of reference, conceived according to the descriptive theory of reference. The intentionality de se is peculiar precisely by the fact that in this case the reference cannot fail and uniquely individuates the haecceitas of the intentional subject. (shrink)
