This article is devoted to the characterization of the basin of attraction of pattern solutions for some slow–fast reaction–diffusion systems with a symmetric property and an underlying oscillatory reaction part. We characterize some subsets of initial conditions that prevent the dynamical system to evolve asymptotically toward solutions which are homogeneous in space. We also perform numerical simulations that illustrate theoretical results and give rise to symmetric and non-symmetric pattern solutions. We obtain these last solutions by choosing particular random initial conditions.

© 2016 Regents of the University of California.The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous (...) tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group. The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available. (shrink)

According to the resemblance account of 'what it's like' and similar constructions, a sentence such as 'there is something it’s like to have a toothache' means 'there is something having a toothache resembles'. This account has proved controversial in the literature; some writers endorse it, many reject it. We show that this conflict is illusory. Drawing on the semantics of intensional transitive verbs, we show that there are two versions of the resemblance account, depending on whether 'resembles' is construed notionally (...) or relationally. While well-known criticisms of the resemblance account undermine its relational version, they do not touch its notional version. On the contrary, the notional version is equivalent to various accounts usually interpreted as rivals to resemblance. We end by noting that this resolution of the controversy (a) explains why 'like', which is a comparative, appears in a construction that concerns the properties of events, and (b) removes any pressure to suppose that 'like' is ambiguous between a comparative and a non-comparative sense.

There is good reason to think that, in every case of perceptual consciousness, there is something of which we are conscious; but there is also good reason to think that, in some cases of perceptual consciousness—for instance, hallucinations—there is nothing of which we are conscious. This paper resolves this inconsistency—which we call the presentation problem—by (a) arguing that ‘conscious of’ and related expressions function as intensional transitive verbs and (b) defending a particular semantic approach to such verbs, on which they (...) have readings that lack direct objects or themes. The paper further argues that this approach serves not only as a linguistic proposal about the semantics of ‘conscious of’, but also as a proposal about the metaphysics of conscious states. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Zhuangzi:Personal Freedom and/or Incongruity of Names?Paul J. D'Ambrosio (bio)Tao Jiang's Origins of Moral-Political Philosophy in Early China: Contestation of Humaneness, Justice, and Personal Freedom (hereafter Origins) has sparked much scholarly debate. Already numerous presentations, various types of discussions, and reviews have appeared based on Origins. The present review focuses specifically on the Zhuangzi chapter. The entire project actually began, Jiang writes, fifteen years ago as a book (...) on the Zhuangzi. Through his research Jiang realized he needed to learn more about the objects of philosophical ridicule and critique in the Zhuangzi. Origins is the result of this decade-and-a-half study.Origins provides a somewhat novel framework for reading Warring States period philosophy. Summarizing the basic structure of his project Jiang writes: "I make the case that the philosophical dialectics between the partialist humaneness and imperialist justice formed the fundamental dynamics underlying the mainstream moral-political project during the classic period, with the musing on personal freedom as the outlier" (p. 35). As Karyn Lai puts it, Origins revolves around a "predictable set of inherited pre-Qin texts associated with key figures, traditionally called the "Masters" (zi 子) text" (Lai 2022, p. 181). Some models inherited by the "masters," such as yinyang 陰陽 thinking or ming 名 (names) and shi 實 (actualities), are nearly absent in Origins and would cast new light on the project as well [End Page 458] as the tradition. In this review I will first outline Jiang's reading of the Zhuangzi before considering how a richer appreciation of the Chinese tradition, especially its own methodological tools, frameworks, and concepts, could bolster the exciting contributions Origins stands to make. We will start with Jiang's big picture view of the Zhuangzi.In Origins the Zhuangzi is taken to be a completely unique text. It does not engage in the moral and political discourse the other "masters" texts are subsumed by, and instead of supporting either partialist humaneness or impartialist justice it "muses" on personal freedom. Jiang defines: "Personal freedom is understood as the appreciation and cultivation of personal space wherein one can be left alone and enjoy the company of like-minded friends without being entangled in the sociopolitical world" (p. 36). There are two significant points to note about Jiang's understanding of freedom. First, it is almost a word-for-character definition of how the "Seven Worthies of the Bamboo Grove" have been described by many. Research on these philosophical works could significantly enrich Jiang's reading, albeit from a different angle. Second, Guo Xiang's 郭象 (d. 312) emphasis on, and philosophical explorations of, du 獨 (an interconnected type of "lone") would further fill out how freedom and relationality—which are both attributed to the Zhuangzi by Jiang—are connected.In addition to a "fierce advocacy for personal freedom" Jiang classifies the Zhuangzi as a "singular outlier" for ridiculing the "misguided character of [the contestations between humaneness and justice] and warn[ing] against their potential for inhumanity and injustice" (p. 49). Indeed, the Zhuangzi does demonstrate that these discussions can elicit "the very opposite of what was intended by the participants of the mainstream discourse" (p. 49). Its criticisms are even more penetrating when we appreciate its deeper point about "names being the guests of actualities" (Zhuangzi 1:4). From this perspective the Zhuangzi is not against systems of humaneness or justice as such. It rather points out that humaneness does not have a single referent, nor could that referent be reliably distinguished. The name "humane" does not guarantee humane action, or really anything in particular. The same is true for "justice." We will return to these points below.Jiang's chapter on the Zhuangzi begins by defending moral and political readings of the text. It is an outlier from the perspective of the "humanity-justice" framework, but this only means that the moral-political discourse Zhuangists were engaged in was different. The result was that already by the early Han and by the time of Sima Qian 司馬遷 (d. 86 b.c.e.) "Zhuangzi's teachings were … of little use to contemporary political discourse" (p. 288). Jiang should be delighted to know that the Wei-Jin period, which had inestimable... (shrink)

Francis J. Ambrosiso begins with sentence that is either self-effacing or alarming “Truly, I do not know why I must write this book, so I must begin by asking for your forgiveness for having done son without knowing why and therefore, necessarily, without knowing how.” An Associate Professor of Philosophy at Georgetown University, Ambrosio believes “the difference the book makes is this: it traces and remarks in the texts of Dante and Derrida two episodes in the history of forgiveness” (...)

The verb 'imagine' admits of perspectival modification: we can imagine things from above, from a distant point of view, or from the point of view of a Russian. But in such cases, there need be no person, either real or imagined, who is above or distant from what is imagined, or who has the point of view of a Russian. We call this the puzzle of perspectival displacement. This paper sets out the puzzle, shows how it does not just concern (...) language, but also states of imagining themselves, and then presents a solution. The solution draws on the idea that many reports of imagining conceal a distinctive kind of question, and such concealed questions have an extra argument place for (what we will call) an experiencer from whose perspective things are imagined. This solution has a range of advantages over other proposals in the literature, and helps to advance two debates concerning perspectival engagement with fiction. (shrink)

Vendler’s :161–173, 1979) puzzle about imagination is that the sentences ‘Imagine swimming in that water’ and ‘Imagine yourself swimming in that water’ seem at once semantically different and semantically the same. They seem semantically different, since the first requires you to imagine ’from the inside’, while the second allows you to imagine ’from the outside.’ They seem semantically the same, since despite superficial dissimilarity, there is good reason to think that they are syntactically and lexically identical. This paper sets out (...) the puzzle and offers a novel solution. Our proposal is that, just as there is knowledge-wh, there is also imagining-wh and that the inside/outside distinction Vendler points to is properly understood as a distinction within imagining-wh. In particular, to imagine swimming from the inside is to imagine what it feels like to swim, while to imagine swimming from the outside is to imagine what it looks like to swim. We show that this proposal is well grounded in both the semantics and syntax of ‘imagine.’ We also argue it makes better sense than its rivals of the data Vendler found so puzzling. (shrink)

Much contemporary scholarship on ziran and wuwei views these concepts, which are often coupled, as being 1) anti-intention, effort, purpose, and self-consciousness; 2) indicative of a distinct type of ethics and/or morality; and 3) a rejection of following custom and convention. This paper will draw largely on the philosophy of Guo Xiang to demonstrate that these widely agreed upon avenues of interpretation are limited and run contrary to other more nuanced readings of ziran and wuwei. I argue that ziran and (...) wuwei are better appreciated as speaking to attitudes, that they should be understood in terms of degrees rather than categories, and that the Laozi and Zhuangzi offer them as advice for ways of reflecting—they are not standardizable ethical rules. In this way, we can see how ziran and wuwei include intention and effort, are anti (most forms of) ethics and morality, and are inherently intertwined with customs and convention. (shrink)

More and more, we present ourselves and encounter others through profiles. A profile shows us not as we are seen directly but how we are perceived by a broader public. As we observe how others observe us, we calibrate our self-presentation accordingly. Profile-based identity is evident everywhere from pop culture to politics, marketing to morality. But all too often critics simply denounce this alleged superficiality in defense of some supposedly pure ideal of authentic or sincere expression. This book argues that (...) the profile marks an epochal shift in our concept of identity and demonstrates why that matters. You and Your Profile blends social theory, philosophy, and cultural critique to unfold an exploration of the way we have come to experience the world. Instead of polemicizing against the profile, Hans-Georg Moeller and Paul J. D’Ambrosio outline how it works, how we readily apply it in our daily lives, and how it shapes our values—personally, economically, and ethically. They develop a practical vocabulary of life in the digital age. Informed by the Daoist tradition, they suggest strategies for handling the pressure of social media by distancing oneself from one’s public face. A deft and wide-ranging consideration of our era’s identity crisis, this book provides vital clues on how to stay sane in a time of proliferating profiles. (shrink)

In this paper we will discuss some basic aspects of the global theory of dynamical systems. Rather than entering in technical derivations, we will try to emphasize the main points of the concept of dynamical systems which lead us to the generalization presented here, as well as some results that are easily generalized. Besides, some considerations of philosophical nature will be made.

The ideals of creativity and equality are expressed in what the education system pretends to be, not what it is. Creativity in education is the idea that each student is a unique creative individual whose cultivation of his/her "inner self" is fostered by the education system. Equality is said to exist because students are supposed to be marked or graded equally, thereby allowing all students equal opportunity to communicate in education. These ideal values of how education should be are considered (...) good because they allow educators and politicians to develop policies that are supposed to steer the education system closer to them. Furthermore, it is commonly believed that these ideals, though not fully actualized, are to some extent realized in the current system of education in North America. Many students believe that the education system is largely humane, their individual ideas matter, and are judged with some degree of fairness. When students apply to universities they do so believing that they will be considered as persons, equally among other persons. However, the reality of the system of education is far from being either creative or equal. Communication in education that exists today does not reflect the student's "inner self" nor does the educational system foster genuine equality. In reality, the best way for a student to be accepted into a university is by creating the finest possible application, and to do so students should abandon the ideals of creativity and equality.

This dissertation lays the foundation for a new theory of non-relational intentionality. The thesis is divided into an introduction and three main chapters, each of which serves as an essential part of an overarching argument. The argument yields, as its conclusion, a new account of how language and thought can exhibit intentionality intrinsically, so that representation can occur in the absence of some thing that is represented. The overarching argument has two components: first, that intentionality can be profi tably studied (...) through examination of the semantics of intensional transitive verbs (ITVs), and second, that providing intensional transitive verbs with a nonrelational semantics will serve to provide us with (at least the beginnings of) a non-relational theory of intentionality. This approach is a generalization of Anscombe's views on perception. Anscombe held that perceptual verbs such as "see" and "perceive" were ITVs, and that understanding the semantics of their object positions could help us to solve the problems of hallucination and illusion, and provide a theory of perception more generally. I propose to apply this strategy to intentional states and the puzzles of intentionality more generally, and so Anscombe's influence will be felt all through the dissertation. -/- In the first chapter, titled "Semantic Verbs are Intensional Transitives", I argue that semantic verbs such as "refers to", "applies to", and "is true of" have all of the features of intensional transitive verbs, and discuss the consequences of this claim for semantic theory and the philosophy of language. One theoretically enriching consequence of this view is that it allows us to perspicuously express, and partially reconcile two opposing views on the nature and subject-matter of semantics: the Chomskian view, on which semantics is an internalistic enterprise concerning speakers' psychologies, and the Lewisian view, on which semantics is a fully externalistic enterprise issuing in theorems about how the world must look for our natural language sentences to be true. Intensional Transitive Verbs have two readings: a de dicto reading and a de re reading; the de dicto reading of ITVs is plausibly a nonrelational reading, and the intensional features peculiar to this reading make it suitable for expressing a Chomskian, internalist semantic program. On the other hand, the de re reading is fully relational, and make it suitable for expressing the kinds of word-world relations essential to the Lewisian conception of semantics. And since the de dicto and de re readings are plausibly related as two distinct scopal readings of the very same semantic postulates, we can see these two conceptions of semantics as related by two scopal readings of the very same semantic postulates. -/- In chapter two, titled "Hallucination and the New Problem of Empty Names", I argue that the problem of hallucination and the problem of empty names are, at bottom, the same problem. I argue for this by reconstructing the problem of empty names in way that is novel, but implicit in much of the discussion on empty names. I then show how, once recast in this light, the two problems are structurally identical down to an extremely fine level of granularity, and also substantially overlap in terms of their content. If the problems are identical in the way I propose, then we should expect that their spaces of solutions are also identical, and there is signi cant support for this conclusion. However, there are some proposed solutions to the problem of hallucination that have been overlooked as potential solutions to the problem of empty names, and this realization opens new non-relational approaches to the problem of empty names, and to the nature of meaning more generally. -/- In chapter three, titled "Intensionality is Additional Phrasal Unity", I argue for a novel approach to the semantics of intensional contexts. At the heart of my proposal is the Quinean view that intensional contexts should, from the perspective of the semantics, be treated as units, with the material in them contributing to the formation of a single predicate. However, this proposal is subject to a number of objections, including the criticism that taken at face value, this would render intensional contexts, which seem to be fully productive, non-compositional. I begin by discussing the concept of the unity of the phrase, and pointing to various ways that phrases can gain additional unity. I then proposes that the intensionality of intensional transitive verbs is best construed as a form of semantic incorporation; ITVs, on their intensional readings, meet all of the criteria for qualifying as incorporating the nominals in their object positions. I then give a semantics for ITVs that builds on existing views of the semantics of incorporation structures, and gesture at how this can be extended to intensional clausal verbs, including the so-called propositional attitude verbs.

This research aims to examine access to medical treatment during the COVID-19 pandemic for people living with disabilities. During the COVID-19 pandemic, the practical and ethical problems of allocating limited medical resources such as intensive care unit beds and ventilators became critical. Although different countries have proposed different guidelines to manage this emergency, these proposed criteria do not sufficiently consider people living with disabilities. People living with disabilities are therefore at a higher risk of exclusion from medical treatments as physicians (...) tend to assume they have poor quality of life, whereas access to medical treatment should be based on several parameters, including clinical data and prognosis. However, the COVID-19 pandemic shifts the medical paradigm from person-centred medicine to community-centred medicine, challenging the main ethical theories. We reviewed the main guidelines and recommendations for resources allocation and examined their position toward persons with disabilities. Based on our findings, we propose criteria for not discriminating against people with disabilities in allocating resources. The shift from person-centred to community-centred medicine offers opportunities but also risks sacrificing the most vulnerable people. The principle of reasonable accommodation must always be considered to guarantee the rights of persons with disabilities. (shrink)

Multidimensional adjectives are ubiquitous in natural language. An adjective F is multidimensional just in case whether F applies to an object or pair of objects depends on how those objects stand with respect to multiple underlying dimensions of F-ness. Developing a semantics for multidimensional adjectives requires us to address the problem of dimensional aggregation: how do the application conditions of an adjective F in its positive and comparative forms depend on its underlying dimensions? Here we develop a semantics for multidimensional (...) adjectives that incorporates aggregation functions. We then explore an analogy between dimensional aggregation and preference aggregation, bringing results from social choice theory to bear on the number and kind of aggregation functions that are admissible in a context. These results suggest that, for any given adjective, there will often be multiple aggregation functions admissible, meaning that multidimensional comparatives are often vague. (shrink)

In this paper, I develop and defend a new adverbial theory of perception. I first present a semantics for direct-object perceptual reports that treats their object positions as supplying adverbial modifiers, and I show how this semantics definitively solves the many-property problem for adverbialism. My solution is distinctive in that it articulates adverbialism from within a well-established formal semantic framework and ties adverbialism to a plausible semantics for perceptual reports in English. I then go on to present adverbialism as a (...) theory of the metaphysics of perception. The metaphysics I develop treats adverbial perception as a directed activity: it is an activity with success conditions. When perception is successful, the agent bears a relation to a concrete particular, but perception need not be successful; this allows perception to be fundamentally non-relational. The result is a novel formulation of adverbialism that eliminates the need for representational contents, but also treats successful and unsuccessful perceptual events as having a fundamental common factor.

Information is a force multiplier. Knowledge of the enemy's capability and intentions may be of far more value to a military force than additional troops or firepower. Situation assessment is the ongoing process of inferring relevant information about the forces of concern in a military situation. Relevant information can include force types, firepower, location, and past, present and future course of action. Situation assessment involves the incorporation of uncertain evidence from diverse sources. These include photographs, radar scans, and other forms (...) of image intelligence, or IMINT; electronics intelligence, or ELINT, derived from characteristics (e.g., wavelength) of emissions generated by enemy equipment; communications intelligence, or COMINT, derived from the characteristics of messages sent by the enemy; and reports from human informants (HUMINT). These sources must be combined to form a model of the situation. The sheer volume of data, the ubiquity of uncertainty, the number and complexity of hypotheses to consider, the high-stakes environment, the compressed time frame, and deception and damage from hostile forces, combine to present a staggeringly complex problem. Even if one could formulate a decision problem in reasonable time, explicit determination of an optimal decision policy exceeds any reasonable computational resources. While it is tempting to drop any attempt at rational analysis and rely purely on simple heuristics, we argue that this can lead to catastrophic outcomes. We present an architecture for a ``complex decision machine'' that performs rational deliberation to make decisions in real time. We argue that resource limits require such an architecture to be grounded in simple heuristic reactive processes. We thus argue that both simple heuristics and complex decision machines are required for effective decision making in real time for complex problems. We describe an implementation of our architecture applied to the problem of military situation assessment. (shrink)

In this paper I show that we have strong empirical and theoretical reasons to treat the verbs we use in our semantic theorizing—particularly ‘refers to ’, ‘applies to ’, and ‘is true of ’—as intensional transitive verbs. Stating our semantic theories with intensional vocabulary allows us to partially reconcile two competing approaches to the nature and subject-matter of semantics: the Chomskian approach, on which semantics is non-relational, internalistic, and concerns the psychology of language users, and the Lewisian approach, on which (...) semantics is fully relational, specifies truth-conditions, and has metaphysical implications. ITVs have two readings: an intensional, de dicto reading, and a relational, de re reading. A semantic theory stated with the de dicto readings of our semantic verbs captures the core insights of the Chomskian approach to semantics, in part because it allows us to assign extremely fine-grained semantic values to expressions, even when those expressions are empty. On the other hand, the de re reading yields a theory that is fully relational, and issues in truth-conditions. The resulting theories are related—and compatible—in that they are expressed by two different readings of the very same semantic vocabulary, and plausibly, the distinction between these two readings is one of scope.

I develop an account of scientific representations building on Charles S. Peirce's rich, and still underexplored, notion of iconicity. Iconic representations occupy a central place in Peirce's philosophy, in his innovative approach to logic and in his practice as a scientist. Starting from a discussion of Peirce's approach to diagrams, I claim that Peirce's own representations are in line with his formulation of iconicity, and that they are more broadly connected to the pragmatist philosophy he developed in parallel with his (...) scientific work. I then defend the contemporary relevance of Peirce's approach to iconic representations, and specifically argue that Peirce offers a useful ‘third way’ between what Mauricio Suárez has recently described as the ‘analytical’ and ‘practical’ inquiries into the concept of representation. As a philosophically minded scientist and an experimentally inclined philosopher, Peirce never divorced the practice of representing from questions about what counts as a representation... (shrink)

The many-property problem has traditionally been taken to show that the adverbial theory of perception is untenable. This paper first shows that several widely accepted views concerning the nature of perception---including both representational and non-representational views---likewise face the many-property problem. It then presents a solution to the many-property problem for these views, but goes on to show how this solution can be adapted to provide a novel, fully compositional solution to the many-property problem for adverbialism. Thus, with respect to the (...) many-property problem, adverbialism and several widely accepted views in the philosophy of perception are on a par, and the problem is solved. (shrink)

The study examines how truth-tellers and truth-telling can be cultivated in the context of post-truth politics in the U.S. Following Foucault, it is not concerned with examining the problem of truth, with the philosophical question of how truth is determined, but with the problem of truth-tellers or truth-telling as a practical activity of self-improvement. To this end, the study traces the emergence and nature of post-truth politics in the U.S. and analyzes its relation to patterns of fascist propaganda and the (...) psychological appeal of authoritarian leaders through a psycho-social perspective. To counter the nature and ubiquity of post-truth politics, the unrelenting flow of lies, disinformation, and conspiracy theories disseminated by the far-right news and information ecosystem, the author argues that educators can help students recognize truth-tellers and become truth-tellers themselves by employing certain pedagogical strategies, informed by Foucault’s analysis of parrhesia, that can equip them to criticize and resist post-truth propaganda and demagogues.

First published in 1986, Knowledge, Belief, and Witchcraft remains the only analysis of indigenous discourse about an African belief system undertaken from within the framework of Anglo-American analytical philosophy.

Prior’s puzzle is standardly taken to be the puzzle of why, given the assumption that that-clauses denote propositions, substitution of “the proposition that P” for “that P” within the complements of many propositional attitude verbs is invalid. I show that Prior’s puzzle is much more general than is ordinarily supposed. There are two variants on the substitutional form of the puzzle—a quantificational variant and a pronominal variant—and all three forms of the puzzle arise in a wide range of grammatical positions, (...) rather than merely in the complements of propositional attitude verbs. The generalized puzzle shows that a range of proposed solutions to the original puzzle fail, or are radically incomplete, and also reveals the connections between Prior’s puzzle and debates over the nature of semantic types and higher-order quantification. I go on to develop a novel, higher-order solution to the generalized form of the puzzle, and I argue that this higher-approach is superior to its first-order alternatives. (shrink)

Ramsification is a well-known method of defining theoretical terms that figures centrally in a wide range of debates in metaphysics. Prior's puzzle is the puzzle of why, given the assumption that that-clauses denote propositions, substitution of "the proposition that P" for "that P" within the complements of many propositional attitude verbs sometimes fails to preserve truth, and other times fails to preserve grammaticality. On the surface, Ramsification and Prior's puzzle appear to have little to do with each other. But Prior's (...) puzzle is much more general than is ordinarily appreciated, and Ramsification requires a solution to the generalized form of Prior's puzzle. Without such a solution, a wide range of theories will either fail to imply their Ramsey sentences, or have Ramsey sentences that are ill-formed. As a consequence, definitions of theoretical terms given using the Ramsey sentence will be either incorrect or nonsensical. I present a partial solution to the puzzle that requires making use of a neo-Davidsonian language for scientific theorizing, but the would-be Ramsifier still faces serious challenges. (shrink)

In this paper I present an empirical solution to the puzzle of Macbeth's dagger. The puzzle of Macbeth's dagger is the question of whether, in having his fatal vision of a dagger, Macbeth sees a dagger. I answer this question by addressing a more general one: the question of whether perceptual verbs are intensional transitive verbs (ITVs). I present seven experiments, each of which tests a collection of perceptual verbs for one of the three features characteristic of ITVs. One of (...) these features is Nonexistence: the failure of sentences involving transitive verbs to entail the existence of their direct objects. The experiments reveal that with respect to all three of these features, "see" behaves much more like a paradigmatically extensional verb than an intensional one. But surprisingly, unlike "see", "perceive" behaves much more like a paradigmatically intensional verb. This shows that the category of perceptual verbs is not uniform with respect to the features of intensionality; while Macbeth does not see a dagger, he may still perceive one. (shrink)

The classification of the sciences is one of the most discussed and analysed aspects of Peirce’s corpus of work. I propose that Peirce’s attempt at systematising the sciences is characterised by a distinctive historicity, which I construe in two complementary senses. First, I investigate Peirce’s classification as part of a broader nineteenth-century move toward classifying the sciences, a move that was at the same time motivated by social and epistemological goals. I claim that this re-contextualisation adds an entirely new layer (...) to the otherwise distinctively internalist readings of Peirce’s classification. I then look at how Peirce’s scheme, especially in the form it displayed in the early 1890s, relates to his own historical writings, particularly his history of science. Looking at Peirce as a historical actor in his own right through the lens of his classification, I claim, is indispensable to understand the contemporary relevance of his contributions to the history and historiography of the sciences.

This essay attempts to provide a preliminary outline of a theory of identity. The first section addresses what the sociologist Niklas Luhmann has called ‘the problem of identity’, or, in other words, the mind–society (rather than the mind–body) problem: In how far can the internal (psychological) self and the external (social) persona be integrated into a unit? The second section of the essay briefly defines a basic vocabulary of a theory of identity. ‘Identity’ is understood as the existentially necessary formation (...) of a coherence between the ‘self’ (the ‘I’ as it is experienced in thoughts and feelings), its body and its social ‘persona’ (the individual person with its social attributes). Three different major paradigms of identity formation are distinguished from one another: a sincere identity is constructed through a firm commitment of the self to its social roles; an authentic identity is constructed through the creation of a social persona on the basis of one’s unique and original self; a ‘profilic’ identity, as we call it, is shaped by successfully presenting a personal profile under conditions of second-order observation as they prevail, for instance, in the social media, but also in other contemporary social systems. In the third section of the essay, we present a sketch of the historical sequence of these three paradigms of identity. Although these paradigms are not mutually exclusive and can coexist, it seems that sincerity flourished in pre-modern society, while authenticity came to prominence along with the functional differentiation of modern society and is now, along with the increased significance of second-order observation, gradually overshadowed by the influence of profilicity.
