The concept of agency is of crucial importance in cognitive science and artificial intelligence, and it is often used as an intuitive and rather uncontroversial term, in contrast to more abstract and theoretically heavy-weighted terms like “intentionality”, “rationality” or “mind”. However, most of the available definitions of agency are either too loose or unspecific to allow for a progressive scientific program. They implicitly and unproblematically assume the features that characterize agents, thus obscuring the full potential and challenge of modeling agency. (...) We identify three conditions that a system must meet in order to be considered as a genuine agent: a) a system must define its own individuality, b) it must be the active source of activity in its environment (interactionalasymmetry) and c) it must regulate this activity in relation to certain norms (normativity). We find that even minimal forms of proto-celular systems can already provide a paradigmatic example of genuine agency. By abstracting away some specific details of minimal models of living agency we define the kind of organization that is capable to meet the required conditions for agency (which is not restricted to living organisms). On this basis, we define agency as an autonomous organization that adaptively regulates its coupling with its environment and contributes to sustaining itself as a consequence. We find that spatiality and temporality are the two fundamental domains in which agency spans at different scales. We conclude by giving an outlook to the road that lies ahead in the pursuit to understand, model and synthesis agents. (shrink)

The unique discourse of Confucian ritual practice encompasses a powerful and sophisticated way of talking about individual fulfillment within the context of more substantive or universal conceptions of the good life. To make this case, I will consider both the text of the "Analects" and the influential readings of the "Analects" offered by Fingarette in "Confucius: The Secular as Sacred" and by Hall and Ames in "Thinking through Confucius". Though the two interpretive works are helpful in articulating the classical Confucian (...) contribution to the problem of balancing conformity and individuality, I will argue that an alternative reading is required to appreciate fully how values thought to embody and express the fullest humanity might be inculcated in ethical agents without undoing their individuality. Such an alternative is developed here. (shrink)

The problem of plant individuality is something which has vexed botanists throughout the ages, with fashion swinging back and forth from treating plants as communities of individuals (Darwin 1800 ; Braun and Stone 1853 ; Münch 1938 ) to treating them as organisms in their own right, and although the latter view has dominated mainstream thought most recently (Harper 1977 ; Cook 1985 ; Ariew and Lewontin 2004 ), a lively debate conducted mostly in Scandinavian journals proves that the (...) issues are far from being resolved (Tuomi and Vuorisalo 1989b ; Fagerström 1992 ; Pan and Price 2001 ). In this paper I settle the matter once and for all, by showing which elements of each side are correct. (shrink)

In contemporary philosophical discourse, there is a widespread assumption that meaning in life is individual: that it is a value inherent in individual human lives, that the content of this meaning varies from individual to individual, and that it differs in degree based on the individual. Despite these claims, however, objectivist theories of meaningful life have so far failed to do full justice to this assumption of individuality, leading to certain deficiencies and distortions in the understanding of meaningful life. (...) This paper aims to highlight these shortcomings and to explain how the individuality of meaning in life can be better understood within an objectivist framework. This proposed individuality account provides a necessary correction and complement to existing objectivist accounts of meaningful life. The paper demonstrates how the individuality account successfully addresses common shortcomings, withstands various objections, and differs significantly from current approaches. (shrink)

The Problem of Biological Individuality is the problem of how to count organisms. Whilst counting organisms may seem easy, the biological world is full of difficult cases such as colonial siphonophores and aspen tree groves. One of the main solutions to the Problem of Biological Individuality is the Physiological Approach. Drawing on an argument made by Eric Olson in the personal identity debate, I argue that the Physiological Approach faces a metaphysical problem - the ‘Foetus Problem’. This paper (...) illustrates how metaphysics can contribute to debates about organisms in the philosophy of biology. (shrink)

In Individuality and Mass Democracy, Alex Zarakas acknowledges the importance of both, but focuses on the responsibility of citizens.

A recent development in biology has been the growing acceptance that holobionts, entities comprised of symbiotic microbes and their host organisms, are widespread in nature. There is agreement that holobionts are evolved outcomes, but disagreement on how to characterize the operation of natural selection on them. The aim of this paper is to articulate the contours of the disagreement. I explain how two distinct foundational accounts of the process of natural selection give rise to competing views about evolutionary individuality.

The paper links discussions of two topics: biological individuality and the simplest forms of mentality. I discuss several attempts to locate the boundary between metabolic activity and ‘minimal cognition.’ I then look at differences between the kinds of individuality present in unicellular life, multicellular life in general, and animals of several kinds. Nervous systems, which are clearly relevant to cognition and subjectivity, also play an important role in the form of individuality seen in animals. The last part (...) of the paper links these biological transitions to the evolutionary history of subjective experience. (shrink)

Two major clarifications have greatly abetted the understanding and fruitful expansion of the theory of natural selection in recent years: the acknowledgment that interactors, not replicators, constitute the causal unit of selection; and the recognition that interactors are Darwinian individuals, and that such individuals exist with potency at several levels of organization (genes, organisms, demes, and species in particular), thus engendering a rich hierarchical theory of selection in contrast with Darwin’s own emphasis on the organismic level. But a piece of (...) the argument has been missing, and individuals at levels distinct from organisms have been denied potency (although granted existence within the undeniable logic of the theory), because they do not achieve individuality with the same devices used by organisms and therefore seem weak by comparison. We show here that different features define Darwinian individuality across scales of size and time. In particular, species-individuals may develop few emergent features as direct adaptations. The interactor approach works with emergent fitnesses, not with emergent features; and species, as a consequence of their different mechanism for achieving individuality (reproductive exclusivity among subparts, that is, among organisms), express many effects from other levels. Organisms, by contrast, suppress upwardly cascading effects, because the organismic style of individuality (by functional integration of subparts) does not permit much competition or differential reproduction of parts from within. Species do not suppress the operation of lower levels; such effects therefore become available as exaptations conferring emergent fitness—a primary source of the different strength that species achieve as effective Darwinian individuals in evolution.

Although natural philosophers have long been interested in individuality, it has been of interest to contemporary philosophers of biology because of its role in different aspects of evolutionary biology. These debates include whether species are individuals or classes, what counts as a unit of selection, and how transitions in individuality occur evolutionarily. Philosophical analyses are often conducted in terms of metaphysics (“what is an individual?”), rather than epistemology (“how can and do researchers conceptualize individuals so as to address (...) some of their scientific goals?”). We review several philosophical distinctions in order to shift attention from metaphysics to epistemology. Many controversies involve epistemological differences rather than metaphysical disagreement. This implies that a pluralist stance about individuality in biology is warranted and has metaphysical consequences because the pluralism emerges from the diversity of scientific interests that investigate the complexity of living phenomena.

The Received View on quantum non-individuality is, roughly speaking, the view according to which quantum objects are not individuals. It seems clear that the RV finds its standard expression nowadays through the use of the formal apparatuses of non-reflexive logics, mainly quasi-set theory. In such logics, the relation of identity is restricted, so that it does not apply for terms denoting quantum particles; this “lack of identity” formally characterizes their non-individuality. We face then a dilemma: on the one (...) hand, identity seems too important to be given up, on the other hand the RV seems to require that identity be given up. In this paper we shall discuss how the specific characterization of the RV through non-reflexive logics came to be framed. We examine some of the main objections to this version of the RV and argue that they are misguided under this specific “non-reflexive” understanding of the RV. Finally, we shall also argue that this non-reflexive view is not the only option for a metaphysical articulation of the RV: less radical approaches to identity and logic are open. In particular, some of these alternative approaches to the RV we present may be immune to most of the criticisms presented against the non-reflexive approach. (shrink)

In discussing cruelty toward human beings, I argue that disregarding the singularity of any human being is necessary for treating her or him cruelly. The cruelty of Peter the Great, relying upon the intolerance of any human singular individuality, serves me as a paradigm-case to illustrate that. The cruelty of Procrustes and that of Stalin rely upon similar grounds. Relating to a person’s singularity is sufficient to prevent cruelty toward that person. In contrast, a liberal state of mind or (...) solidarity is insufficient to prevent cruelty and, under some circumstances, may even cause it. (shrink)

This is a (very) introductory paper to a forthcoming existentalist account of moral absolutism and violence. It was written for and presented at ICPR Seminar 2018. In feminist ethics, the freedom to choose one's way of living is primary to the struggle against patriarchy. Such a choice to live a certain way is a manifestation of one's individuality. This assertion of individuality is accompanied by responsibility towards consequences of the way of living. To explore the relation between (...) class='Hi'>individuality and responsibility, I develop and build the hypothetical situation of a mother and daughter with different ways of living. The notion of a good life for each of them is mentioned and we ask: To what extent is the daughter responsible for the anguish that the mother undergoes in her assertion of individuality (through her choice of way of living)? My primary aim in this paper is to question the nature of individuality and to probe the claim that individuality is a source of violence. This will involve discussing the scope of responsibility for one's choices and the difficulty in forming a criterion to delineate such a scope. (shrink)

Recent attention to complex group-level behavior amongst bacteria has led some to conceive of multicellular clusters of bacteria as individuals. In this article, I assess these recent claims by first drawing a distinction between two concepts of individuality: physiological and evolutionary. I then survey cases that are representative of three different modes of growth: myxobacteria (surface-attached agglomerative growth), Bacillus subtilis (agglomerative growth not attached to a surface), and cyanobacteria (filamentous growth). A closer look at these cases indicates that multicellular (...) individuality among bacteria is remarkably complex. Physiologically, the three cases of multicellular clusters do not form physiological individuals. But matters are different when it comes to evolutionary individuality; although multicellular clusters that grow by agglomeration are not highly individuated, filament-forming groups achieve a relatively high degree of individuality. I also suggest that debates about bacterial multicellular individuality may have been obscured by a failure to see that selection on highly individuated groups is by no means the only mechanism to bring about the complex group-level behaviors that have led some to view bacteria as multicellular individuals.

Recently, in the debate about the ontology of quantum mechanics some authors have defended the view that quantum particles are individuals in a primitive sense, so that individuality should be preferred over non-individuality (the alternative option). Primitive individuality involves two main claims: (1) every item is identical with itself and (2) it is distinct from every other item. Non-relativistic quantum mechanics is said to provide positive evidence for that position, since in every situation comprising multiple particles there (...) is a well-defined number of them to begin with, and so they must be distinct from each other. We argue that the link between a well-defined number of items and the relation of identity that is being claimed to hold is not imposed by quantum mechanics, but rather by a metaphysical view. Formal evidence is advanced in favor of the thesis that counting may be performed for items without identity (non-individuals), so that quantum mechanics needs not be viewed as endorsing an ontology of individuals.

This paper is an application of the principles of individuality found in Guay and Pradeu to illuminate biological individuality in mushrooms. I begin with the distinction between logico-cognitive individuals and ontological individuals, and then I argue for genidentity plus material continuity, as a minimum conception of ontological individuality in biology. Of the many materially-continuous genidenticals found in fungi, only those with functional roles in biological theory, either evolutionary or physiological, warrant consideration. Given numerous ways that theory picks (...) out materially-continuous genidenticals in fungi, I argue for a pluralistic account of mushroom individuality. (shrink)

Individuality has posed difficult problems throughout the history of philosophy. Not only is there the metaphysical difficulty of determining the principle of individuation, but, since our concepts and linguistic structure are based on universals, there is a gap in our knowledge of individuals and in our ability to express knowledge of individuals. God, who in Classical Theism is an individual, poses especially difficult problems. This dissertation proposes one way which may partially close the gap: metaphor. ;I argue that the (...) principle of individuation is what Duns Scotus called haecceitas, which uniquely delimits this particular individual. It is not opposed to form or to universality, but is the ultimate reality of form. I follow Scotus further in holding that the individual qua individual is intrinsically intelligible; our difficulty in understanding individuals is due to the weakness of our intellect, since our thought is through universal concepts. ;Next I defend the interaction theory of metaphor, which holds that the terms of a metaphor interact to form a new meaning which cannot be entirely reduced to the meanings of the terms. I argue further that metaphor can not only give us richer linguistic access to entities, but also give us cognitive insight which cannot be gained in any other way. ;I then defend a form of non-propositional knowing and argue that metaphor is a particularly appropriate way to express this knowledge. I argue that Scotus' theory of individuality, which holds that the individual is intrinsically intelligible, leaves open the possibility of some form of metaphoric cognition of the individual. I present a case study: the poetry of Gerard Manley Hopkins. Hopkins attempted to use metaphor and other devices in his poetry to illuminate individual beings. ;Finally I discuss God, the ultimate instance of the correlation of universality and individuality. God, being the ultimate individual, presents epistemological and linguistic problems similar in some ways to those which accrue to finite individuality. I defend the thesis that metaphorical and modelling language can help us gain insight into God. (shrink)

Integration (interaction among parts of an entity) is suggested to be necessary for individuality (contra, Metaphysics and the Origin of Species). A synchronic species is an integrated individual that can evolve as a unified whole; a diachronic lineage is a non-integrated historical entity that cannot evolve. Synchronic species and diachronic lineages are consequently suggested to be ontologically distinct entities, rather than alternative perspectives of the same underlying entity (contra Baum (1998), Syst. Biol. 47, 641–653; de Queiroz (1995), Endless Forms: (...) Species and Speciation, pp. 57–75; Genes, Categories and Species). Species concepts usually refer to either one or the other entity; for instance, the Biological Species Concept refers to synchronic species, whereas the Cladistic Species Concept refers to diachronic lineages. The debate over species concepts has often failed to recognise this distinction, resulting in invalid comparisons between definitions that attempt to delineate fundamentally different entities.

Kitaro Nishida, a famous Japanese Philosopher and the founder of the Kyoto-School, for the first time in history transformed Zen-Buddhism, which here means especially a Japanese school of Buddhism and whose characteristics consists in its methodological meditation, into a philosophical theory of our existence. On the other hand he transformed western philosophy into a very original form of thought, which at the same time contains oriental elements. As Nishida did the bilateral transformation between western and eastern philosophies, he developed a (...) new perspective on the inquiry concerning the individuality of our personal existence and the relation between Self and the other. In his first Work, “An Inquiry into the good” Nishida examines the characteristics of pure experience, which is not understood from the outside, indirectly, and it is not a passive and static experience like for example in ordinary empiricism. It must be understood as active and creative experience which is experienced from within. In reading Thinkers as Ernst Mach and William James he came to realize that there must be a prereflective, pre-individual, unitary pure experience. This pure experience as ultimate reality on which the individual is based, is systematically self developing and Self-unfolding. In Nishidas understanding the pure experience is the common basis for, and is realized prior, to the distinction between subject and object, the Self and the Other, the Knower and the known. I try to explain how Nishidas approach overcomes this subjectivistic perspective and discuss in which way this standpoint offers a new understanding of the Self and the Other.

Biological individuality is a notoriously thorny topic for biologists and philosophers of biology. In this paper we argue that biological individuality presents multiple, interconnected questions for biologists and philosophers that together form a problem agenda. Using a case study of an interdisciplinary research group in ecology, behavioral and evolutionary biology, we claim that a debate on biological individuality that seeks to account for diverse practices in the biological sciences should be broadened to include and give prominence to (...) questions about uniqueness and temporality. We show that broadening the problem agenda of biological individuality draws attention to underrecognized philosophical issues and discussions and thereby organizes and enriches the existing debate.

All disciplines must define their basic units and core processes. In evolutionary biology, the core process is natural selection and the basic unit of selection and adaptation is the individual. To operationalize the theory of natural selection we must count individuals, as they are the bearers of fitness. While canonical individuals have often been taken to be multicellular organisms, the hierarchy of life shows that new kinds of individuals have evolved. A variety of criteria have been used to define biological (...) individuality. Some criteria rely on the presence/absence of a particular property while others advocate an approach that reflects the process of natural selection. The plethora of approaches to classifying individuality has resulted in confusion regarding how to study individuality in a given taxon. (shrink)

This paper argues that a plant together with the symbiotic fungus attached to its roots, a mycorrhizal collective, is an evolutionary individual, and further, that mycorrhizal individuality has important implications for evolutionary theory. Theoretical individuation is defended and then employed to show that mycorrhizal collectives function as interactors according to David Hull’s replicator-interactor model of evolution by natural selection, and because they have the potential to engage in pseudo-vertical transmission, mycorrhizal collectives also function as Darwinian individuals, according to Peter (...) Godfrey-Smith’s Darwinian Populations model of evolution by natural selection. Mycorrhizae in nature usually connect the roots of multiple plants, so mycorrhizal individuality entails the existence of overlapping evolutionary individuals, and because the potential to engage in pseudo-vertical transmission comes in degrees, it follows that these overlapping evolutionary individuals also come in degrees. I suggest here that the degree of evolutionary individuality in a symbiotic collective corresponds to its probability of reproducing with vertical or pseudo-vertical transmission. This probability constitutes a fourth parameter of graded Darwinian individuality in collective reproducers and warrants an update to Godfrey-Smith’s 3D model. (shrink)

If harm is restricted to mean perceptible damage suffered by an agent against his wishes, so that his mere dislike with no evidence of injury is excluded, then Mill's liberty principle arguably is ‘one very simple principle’ as he claims.

Darwin’s classic ‘Origin of Species’ (Darwin 1859) described forces of selection acting upon individuals, but there remains a great deal of controversy about what exactly the status and definition of a biological individual is.

The aim of this paper is to show that there is a real problem of biological individuality, and an (...) urgent need to arbitrate over the current plethora of solutions to it. (shrink)

This paper addresses questions of friendship and political community by investigating a particular complex case, comradeship in the life of the soldier. Close attention to soldiers’ accounts of their own lives, successes and failures shows that the relationship of friendship to comradeship, and of both to the success of the soldier’s individual and communal life, is complex and tense. I focus on autobiographical accounts of basic training in order to describe, and to explore the tensions between, two positions: (1) Becoming (...) a soldier is a corrupting loss of individuality and moral sensitivity, and friendship is resistance to it. (2) Becoming a soldier is one form of flourishing, and comradeship—the soldier’s distinctive form of friendship—is one of its constitutive virtues. I draw particularly on George Orwell’s account of basic training and fighting in the Spanish Civil War, and on Tim O’Brien’s account of basic training and fighting in Vietnam. (shrink)

The place of the State in Spinoza's ontology has emerged in scholarly literature as one of the most complex issues involving Spinoza's political thought. At issue is whether Spinoza's State is an actual individual with its own conatus . Some consider it a completely real individual, others say that its individuality can only be metaphoric, whilst others point out the conceptual insufficiency of this polarity for explaining the ontological status of political aggregates and try to overcome it through new (...) concepts, such as the multitude, transindividuality, and figuration. In this paper, each of these interpretations is analyzed and dismissed in favour of a new one stating that Spinoza's State is actually a dynamic network of political concepts operating in resemblance of individuality and reflecting the main characteristics of the modern Nation-State.

Quasi-set theory $\cal Q$ allows us to cope with certain collections of objects where the usual notion of identity is not applicable, in the sense that $x = x$ is not a formula, if $x$ is an arbitrary term. $\cal Q$ was partially motivated by the problem of non-individuality in quantum mechanics. In this paper I discuss the range of explanatory power of $\cal Q$ for quantum phenomena which demand some notion of indistinguishability among quantum objects. My main focus (...) is on the double-slit experiment, a major physical phenomenon which was never modeled from a quasi-set-theoretic point of view. The double-slit experiment strongly motivates the concept of degrees of indistinguishability within a field-theoretic approach, and that notion is simply missing in $\cal Q$. Nevertheless, other physical situations may eventually demand a revision on quasi-set theory axioms, if someone intends to use it in the quantum realm for the purpose of a clear discussion about non-individuality. I use this opportunity to suggest another way to cope with identity in quantum theories. (shrink)

Abstract:This article investigates Ahn Changho's notion of 'mutual love', the central features of which present a picture of society in which the selfish desires of free-spirited individuals can be regulated through the self-cultivation of mutual love. Specifically, first, by analyzing Ahn Changho's reconfiguration of the Confucian ideal of parent-child intimacy with mutual love, I will argue that his notion of mutual love sheds light on a hybrid imaginary of modernity that cannot be reduced to either the anti-Western rehabilitation of Confucian (...) 'filial piety' or the pro-Western adaptation of 'individuality'. Second, scrutinizing Ahn Changho's empirical criticism of early modern Korea, which has been termed 'the absence of mutual love', it is proposed that his pragmatic vision of individuality is shaped through non-domination as an alternative to the Weberian framework of modernization in which the processes of individualization and rationalization are unduly opposed to those of cultivating a commonality in a society.

This essay presents an in-depth interpretation of the controversial dialogue in Analects 13.18 through careful and critical investigation of its historical background and philosophical significations. With a clarification of the multifaceted connotations of the word zhi (?, upright, forthright), my study brings out the play of irony in Confucius's words in Analects 13.18. According to my interpretation, not only is Confucius's reaction not inappropriate but it also demonstrates the art of early Confucian moral discretion that was informed by the teaching (...) of quan (? moral discretion). Accordingly, Confucius's judgment of the case embodied a high and bright middle way of moral choice originating in the openness and sincerity of heart. It epitomized a singular moment of deliberation and decision that was responsible for a sinuous opening of piety and individuality within the interplay of conflicting conditions and requisitions.

In this dissertation, I explore the reach of the Evolutionary Contingency Thesis—a view that emphasizes the role of dependency relations and chance in evolution. Contingency produces diverse biological entities, processes, and mechanisms. I analyze the implications of evolution’s contingency in three areas. First, I address the problem of evolutionary individuality, which concerns the nature of entities that selection acts on. If we accept Lewontin’s 1970 view that individuals are selected, then what exactly are these individuals? I argue that evolutionary (...) contingency and its diversity of outcomes causes a plurality of individuality types. These types of individuals emerge, evolve, and disappear through evolution. Second, I defend a disunified model of major transitions in evolution. Major transitions mark pivotal turning points in life’s history, such as the transition from unicellularity to multicellularity. Philosophers and biologists aim to unify evolution’s transitions by establishing a property all major events share. I argue that evolutionary contingency’s emphasis on diversity supports a disunified model of transitions. That is, we should expect numerous kinds of major transitions given the diverse sets of outcomes caused by evolutionary contingency. Finally, I extend the contingency analysis to a topic in philosophy of medicine: The nature of cancer. It is common to view cancer as a by-product of our evolution as multicelled creatures. However, Lean and Plutynski argue that cancer is also a direct product of evolution by selection. In both cases, cancer is characterized in terms of how it functions as an object of selection. I argue that the diversity among cancers suggests philosophers should shift their focus to cancers’ structural differences rather than only their functional similarities. (shrink)

As its subtitle 'Skepticism, Individuality and Chastened Politics' indicates, this book is an exploration of and a largely favorable engagement with salient elements in the thinking of a theorist who is widely regarded as the greatest Anglophone political thinker and among the top rank of philosophical writers generally.

This cycle of cooperation, conflict, and conflict (...) mediation drives evolutionary transitions in individuality. (shrink)

The thesis that species are individuals, and not classes as the traditional view had it, has been influential in the last 25 years. In this paper David Hull's arguments for the thesis are surveyed, as well as some counterarguments presented by Philip Kitcher. It is claimed that though species can be conceptualized as individuals, we are not compelled to view them in that way. The importance of the issue seems to have been somewhat exaggerated. However, it might happen that empirical (...) findings concerning species selection would strengthen the case for the thesis, thereby rendering it straightforwardly empirical. The applicability of teleological explanation is suggested as a criterion for biological individuality. (shrink)
