In Against Purity, Alexis Shotwell proposes a powerful new conception of social movements as custodians for the past and incubators for liberated futures. Against Purity undertakes an analysis that draws on theories of race, disability, gender, and animal ethics as a foundation for an innovative approach to the politics and ethics of responding to systemic problems.

Various ideals of purity are surveyed and discussed. These include the classical Aristotelian ideal, as well as certain neo-classical and contemporary ideals. The focus is on a type of purity ideal I call topical purity. This is purity which emphasizes a certain symmetry between the conceptual resources used to prove a theorem and those needed for the clarification of its content. The basic idea is that the resources of proof ought ideally to be restricted to those (...) which determine its content. (shrink)

Purity is the principle that fundamental facts only have fundamental constituents. In recent years, it has played a significant role in metaphysical theorizing—but its logical foundations are underdeveloped. I argue that recent advances in higher-order logic reveal a subtle ambiguity regarding Purity’s interpretation; there are stronger and weaker versions of that principle. The arguments for Purity only support the weaker interpretation, but arguments that employ it only succeed if the stronger interpretation is true. As a result, nearly (...) every metaphysician who has appealed to Purity has made a mistake—in that the inferences that they make are not justified by the arguments that they provide. (shrink)

Throughout history, mathematicians have expressed preference for solutions to problems that avoid introducing concepts that are in one sense or another “foreign” or “alien” to the problem under investigation. This preference for “purity” (which German writers commonly referred to as “methoden Reinheit”) has taken various forms. It has also been persistent. This notwithstanding, it has not been analyzed at even a basic philosophical level. In this paper we give a basic analysis of one conception of purity—what we call (...) topical purity—and discuss its epistemological significance. (shrink)

Purity is known as an ideal of proof that restricts a proof to notions belonging to the ‘content’ of the theorem. In this paper, our main interest is to develop a conception of purity for formal (natural deduction) proofs. We develop two new notions of purity: one based on an ontological notion of the content of a theorem, and one based on the notions of surrogate ontological content and structural content. From there, we characterize which (classical) first-order (...) natural deduction proofs of a mathematical theorem are pure. Formal proofs that refer to the ontological content of a theorem will be called ‘fully ontologically pure’. Formal proofs that refer to a surrogate ontological content of a theorem will be called ‘secondarily ontologically pure’, because they preserve the structural content of a theorem. We will use interpretations between theories to develop a proof-theoretic criterion that guarantees secondary ontological purity for formal proofs. (shrink)

In this paper I will be concerned primarily with purity in morals. I will begin by considering an analysis of the pure person offered by Nicolai Hartmann. While I think there is much that is correct in his discussion, I will criticize it for focusing on naive innocence. I will then suggest some components of what I refer to as “mature purity,” and contrast it with Hartmann’s conception. I will also consider whether mature purity involves certain sorts (...) of attitudes and feelings, or merely conscientious action. I go on to discuss forms of impurity, and finally to discuss the relation of purity to other virtues. (shrink)

In his 1978 paper “Mathematical Explanation”, Mark Steiner attempts to modernize the Aristotelian idea that to explain a mathematical statement is to deduce it from the essence of entities figuring in the statement, by replacing talk of essences with talk of “characterizing properties”. The language Steiner uses is reminiscent of language used for proofs deemed “pure”, such as Selberg and Erdős’ elementary proofs of the prime number theorem avoiding the complex analysis of earlier proofs. Hilbert characterized pure proofs as those (...) that use only “means that are suggested by the content of the theorem”, a characterization we have elsewhere called “topical purity”. In this paper we will examine the connection between Steiner’s account of mathematical explanation and topical purity. Are Steiner-explanatory proofs necessarily topically pure? Are topically pure proofs necessarily Steiner-explanatory? Answers to these questions will shed light on the general question of the relation between purity and explanatory power. (shrink)

A fundamental fact is “pure” just in case it has no grounded entities—ex. Tokyo, President Biden, the River Nile, {Socrates}, etc.—among its constituents. Purity is the thesis that every fundamental fact is pure. I argue that Purity is false. My argument begins with a familiar conditional: if Purity is true, then there are no fundamental “grounding facts” or facts about what grounds what. This conditional is accepted by virtually all of Purity’s defenders. However, I argue that (...) it is also the first step toward Purity’s undoing. For, if every grounding fact has a ground, then some grounded entities have “groundmates” or distinct grounded entities that share their full grounds. But, if there are groundmates, then Purity is false. So Purity leads to a contradiction. Therefore, it is false. I close by noting that my argument against Purity also gives us a powerful reason to think that some grounding facts are fundamental. (shrink)

Hans Kelsen’s purity thesis is the basic methodological principle of the Pure Theory of Law. Indeed, it is no exaggeration to say that virtually everything that is peculiar to Kelsen’s legal theory stems from the purity thesis. This includes Kelsen’s normativism or non‐naturalism and his polemic against various dualisms in legal science. I set out Kelsen’s position on these issues after looking at the nomenclature of purity in his writings as well as the philosophical and contextual sources (...) of purity as he understands them.

Over the years many mathematicians have voiced a preference for proofs that stay “close” to the statements being proved, avoiding “foreign”, “extraneous”, or “remote” considerations. Such proofs have come to be known as “pure”. Purity issues have arisen repeatedly in the practice of arithmetic; a famous instance is the question of complex-analytic considerations in the proof of the prime number theorem. This article surveys several such issues, and discusses ways in which logical considerations shed light on these issues.

By the early 80s, kids were already trawling the message boards of the Internet for perverse kicks. Well before Star Ways Kid or "flash mobs," one of the first online fads was the "Purity Test," a series of questions to rate your moral purity, from the raunchy to the absurd.The tests would be printed out, brought to school, and pored over with friends in the back of the gym during recess. Then kids would modify the original with their (...) own prurient additions before sending it along. Eventually, the tests became bloated thousand-question Franken-tests that took hours to complete.Doing the test with friends was like playing an endless, filthy, wildly enlightening game of "Did You Ever?"--and because it was a standardized test, you could compare your scores. Assuming everyone was being honest--which they weren't. The Purity Test will offer both a humorous history and analysis of the Purity Test as well as several versions of the test to take at home.

This is a paper on a type of purity of proof I call topical purity. This is purity which, practically speaking, enforces a certain symmetry between the conceptual resources used to prove a theorem and those needed for the clarification of its content. The basic idea is that the resources of proof ought ideally to be restricted to those which determine its content. -/- For some, this has been regarded as an epistemic ideal concerning the type of (...) knowledge that proof ought to or at least might ideally provide. -/- For others, including many working mathematicians, it has been largely a strategic or pragmatic ideal. Even these, however, see it (i.e. the ideal of purity) as serving generally epistemic ends. (shrink)

Standard defences of preservationism, and of the intrinsic value of nature more generally, are vulnerable to at least three objections. The first of these comes from social constructivism, the second from the claim that it is incoherent to argue that nature is both 'other' and something with which we can feel unity, whilst the third links defences of nature to authoritarian objectivism and dangerously misanthropic normative dichotomies which set pure nature against impure humanity. I argue that all these objections may (...) be answered by recasting the relationship between man and nature into a tripartite spectrum of ontological form between nature and artifact, with the key question being the extent to which nature has been humanised in accordance with certain modes of strongly instrumental rationality, these in turn being defined by reference to the split between abstract reason and natural feeling which was exacerbated by specific elements in the Enlightenment period. This new model may grant normative force by linking external nature to a broader conception of human psychological wellbeing than that offered by the quantitatively orientated models of human rationality and agency.

In lieu of an abstract, here is a brief excerpt of the content:Purity and Pollution: Resisting the Rehabilitation of a VirtueAmy Mullin“Purity” is a term used infrequently in contemporary academic literature. A survey of periodical indexes for the past ten years shows that references to purity occur predominantly in metallurgy. Purity is an increasingly important topic in anthropology, religious studies, and history, but it is a decidedly rare concern in philosophy. In my most recent search I (...) found three references.Yet “purity” was once a recurrent term in the philosophical tradition ranging from Plato through Augustine and Kant to Kierkegaard. Today when we encounter the many references to purity in the history of philosophy we too often filter them out. We assume either that “pure” is a generic term for good, or, in what seems a more knowing and sophisticated response, we read “pure” as a code term for chastity or sexual morality, the elimination, suppression or control of sexual desire. In both cases purity is written off either as a generic or as an old fashioned and rather embarrassing virtue. Hence it seems there is little reason for contemporary philosophical investigation into the rhetorical use of the language of purity and pollution.Three assumptions account for the lack of contemporary philosophical interest in the topic. First, it is assumed that purity is no longer a concern in twentieth-century philosophy. Second, purity in historical discourse is considered to be limited to a prudish or downright misogynist hostility to sex. Third and finally, it is assumed that the work historians and anthropologists have done recently into connections between purity beliefs and practices and social cohesion is irrelevant for philosophy. This is because purity in philosophy is supposed to be a resolutely individualist virtue, having little or nothing to do with unified and coherent communities.There are elements of truth to all three beliefs, but they also contain important distortions of the truth. As regards the first assumption, purity remains a concern in contemporary aesthetics, where it often means roughly something like a priori and apolitical; but I am interested in whether the concern with purity has survived in philosophies with ethical implications. [End Page 509] Here it is my contention that authenticity is the twentieth-century descendant of the virtue of purity.Second, there is much more to the rhetoric and practices of purity than concern with the sexual dimension of life, though this is a key aspect of most, and the beliefs and practices are often misogynist. There have been numerous anthropological documentations of ways in which purity beliefs, particularly an emphasis on sexual purity, are used to control women. Santi Rozario’s work, for instance, makes this point in her analysis of contemporary Bengali village life. 1 The connection between the language of purity and the practice of female circumcision, which I will not discuss in this paper, is in itself evidence enough of connections between purity beliefs and practices harmful to women. 2 However, I hope to show that there is more to purity than misogyny. Purity most basically is about order, both social and personal. 3My response to the second assumption, that purity masks an obsession with sexual control, indicates the source of my disagreement with the third, the contention that purity in philosophy is exclusively an individual virtue. Communal beliefs and practices associated with the language of purity and pollution are relevant to the philosophical treatment of purity because of the presence in both the practices and the philosophies of an interplay between social and personal order. As a result I believe an understanding of the dynamics of beliefs about purity in social practice can inform a philosophical concern with purity.First I investigate shifts in beliefs and practices concerning purity and pollution. I will concentrate on three models: ancient Greek (from the eighth to the third century BC), biblical to Talmudic Judaism (from the third century BC to the third century AD), and early Christian (from the first to the fifth century AD). These represent three traditions which have played a very significant role in shaping western civilization, theology, and philosophy. 4 They were also frequently interrelated in this period, as Christian and Jewish Platonists writing in Greek attest and of course as...

Using the concept of purity to reflect on the relationship between chemical practice and the philosophy of science, this article considers the philosophical significance of the chemical manipulations that aim to purify or otherwise transform matter. Starting from a consideration of the nature and role of pure (or idealised) examples in philosophy of science, the article underlines the temptation towards abstraction and theory for both scientists and philosophers. The article goes on to argue that chemistry, despite its increasing theoretical (...) sophistication, is a science that remains particularly close to laboratory manipulations. This point is made in reference to the work of Gaston Bachelard on the production of purity and with the aid of historical examples, notably exploring the interplay between techniques of purification and the definition of elements, with special attention paid to Lavoisier’s definition of elements as the final limit of analysis. The closing section concerns the manufacture of steel from iron ore in the eighteenth century, illustrating this process using texts by Pierre-Joseph Macquer and Denis Diderot. Steel production is used to illustrate the kinds of philosophical question that are raised by paying attention to the details of chemical practice rather than jumping straight to chemical theory and also suggests how scientific theory can emerge from this practice itself.

Through a reinterpretation of publications, interviews with long-term activists, and an analysis of change in the social environment, this article explains why feminist ideology failed to create unity among feminist women in the United States during the period 1966-1975, the years when contemporary feminism emerged. In spite of the desire to create a community of women to challenge the existing sociocultural structure, schisms within the movement often created divisive and antagonistic feminist group relations. In contrast to earlier research that attributed (...) this lack of unity to competing ideologies, this article argues that, in many cases, feminist leaders used ideology and theory to promote radical self-identities that maintained existing social structural divisions. Thus, while feminism established a principle of unity for women as a group, disputes over ideological purity created divisions within the movement based on differences among women. (shrink)

Turning to the question of morality's content, Scheffler undertakes a defense of the view that morality is moderate – that it makes demands and imposes constraints but still allows people, under favorable circumstances, to do as they please within broad limits. Those who oppose this view and see morality as stringent are, according to Scheffler, attributing a kind of purity to the moral point of view, and so he presents the contrast between the stringent and moderate views as a (...) contrast between an Ideal of Purity and an Ideal of Humanity. Scheffler considers and rejects two argumentative strategies that are frequently used in defense of the Ideal of Purity, one that derives stringency from an allegedly uncontroversial property of morality, such as universality or impartiality and another that derives it from ordinary moral language and ordinary moral concepts. Scheffler suggests that, because the claims of stringency and moderation each have a place in our moral consciousness, neither claim can be adequately defended by appealing either to formal properties of morality or to facts about ordinary usage.

Rarely has a philosopher demanded such a purity of moral motives. Even when he discusses those “many spirits of so sympathetic a temper that, without any further motive of vanity or self-interest, they find an inner pleasure in spreading happiness around them and can take delight in the contentment of others as their own work,” Kant maintains that, “in such a case an action of this kind, however right and however amiable it may be, still has no genuinely moral (...) worth.” Because the action is done from inclination rather than duty, it cannot qualify as a morally good action in Kant’s eyes. Indeed, this seems to suggest that from a moral point of view the person who is naturally unsympathetic to others almost has an advantage, at least in terms of the opportunity for moral action, over those who are naturally inclined to altruistic acts. Kant hardly seems to shrink from such a conclusion. His own words best convey his position here. (shrink)

In this paper, I draw on the principles of Aristotelian ethics, the work of modern virtue ethicists, and previous feminist critiques of purity balls to interrogate the effects of this practice on moral development. I argue that purity balls discourage young women from making autonomous, informed, and virtuously motivated decisions regarding their sexuality. While most critiques of purity balls are rooted in the explicitly patriarchal structure of these events, my analysis emphasizes the negative impact they have on (...) moral agency. I conclude that purity balls are unethical because of the detrimental effects they have on the becoming of virtuous agents. (shrink)

ArgumentAfter World War II, blood groups became a symbol of anti-racial science. This paper aims to shed new light on the post-WWII history of blood groups and race, illuminating the postcolonial revitalization of racial serology in South Korea. In the prewar period, Japanese serologists developed a serological anthropology of Koreans in tandem with Japanese colonialism. The pioneering Korean hematologist Yi Samyŏl (1926–2015), inspired by decolonization movements during the 1960s, excavated and appropriated colonial serological anthropology to prove Koreans as biologically independent (...) from the Japanese. However, his racial serology of Koreans shared colonial racism with Japanese anthropology, despite his anti-colonial nationalism. (shrink)

_Purpose._ The purity of consciousness in European culture has practically been turned into an abstraction. Because of this, there are so many discrepancies in understanding its nature. For Heidegger, the question of the purity of human consciousness remains open. Our purpose is to study the purity of European consciousness in the work of M. Heidegger. _Theoretical basis._ We draw on the deep foundations of existential, phenomenological, hermeneutic, religious-philosophical and postmodern Western and Eastern thought. _Originality._ While the early (...) Heidegger was thinking under the sign of Dasein, he did not hear the nature of the "pure consciousness" of human. Nevertheless, temporality for him was such a fundamental property that it determined the depth of understanding not only of being, but also of human consciousness itself (like Dasein). In this context, we begin to understand that the depth of consciousness in the concept of early Heidegger can be associated with its temporality. In fact, towards the end of "Being and Time", Heidegger, thinking more and more about the understanding of time from the horizon of being, begins to form similar ideas about understanding itself, that is, about human consciousness, in the sense that consciousness itself arises from the horizon of time (and being). What, then, is pure human consciousness the pure time? Does not this mean that the original meaning of consciousness is in its directed temporalizing. This temporalizing of consciousness of human (as a thinking being), which arises from the future, is perceived in three modes and reveals the fundamental nature of the consciousness itself (thinking is a stream of consciousness and, in such a context, directed understanding). Paraphrasing Heidegger, we say that the ontological meaning of pure human consciousness is revealed as temporality. Already after writing _Being and Time_, Heidegger thinks about the origins of the European consciousness, its comprehending from the depths (originality) of the being of European culture. _Conclusions._ The early Heidegger seeks the purity of being and, at the same time, strives more and more to understand the essence of the purity of human thinking. All of Heidegger’s work is a consistent transition from human understanding of the purity of being (Dasein) to the purity of thinking of a human himself. In this sense, there is a transformation of M. Heidegger’s consciousness from fundamental ontology (Dasein) in the early period to existential anthropology (human consciousness) in the late period.

The issues of climate change and environmental degradation elicit diverse responses. This paper explores how an understanding of human moral psychology might be used to motivate conservation efforts. Moral concerns for the environment can relate to issues of harm or impurity . Aversions to harm are linked to concern for current or future generations, non-human animals, and anthropomorphized aspects of the environment. Concerns for purity are linked to viewing the environment as imbued with sacred value and therefore worthy of (...) being protected at all costs. While both harm-based and purity-based framings of environmental issues can sometimes backfire, we argue that making these moral concerns salient can nevertheless bring about moral responses to environmental issues. In sum, scientists' emerging knowledge about the moral mind can be used to facilitate the sustainable conservation of the planet. (shrink)

Purity violations overlap with other moral domains. They are not uniquely characterized by hypothesized markers of purity – the witness's emotion of disgust, taint to perpetrator's soul, or the diminished role of intention in moral judgment. Thus, Fitouchi et al.'s proposition that puritanical morality (a subset of violations in the purity domain) is part of cooperation-based morality is an important advance.

In his penetrating and thought-provoking article “What Is Logic?” Ian Hacking flags an issue that he leaves undiscussed.

"Moore's provocative conclusion is that monotheism - with its monopoly on virtue and failure to provide supernatural scapegoats - is responsible for some of the most virulent forms of intolerance and is a major cause of human nastiness and suffering.

Nietzsche’s relationship to his contemporaries, as expressed in his writings, was often figured by corporeal imagery evocative of disgust. For instance, in On the Genealogy of Morality Nietzsche declared himself to suffer from mankind—which he then proceeds to describe as “maggot”—or worm-like. Nietzsche’s philosophical project can be interpreted as a visceral protest against, and attempt to overcome, humanity. This paper argues that Nietzsche attempted through his writings to create a future community of like-constituted companions in his readers through a transmission (...) of affect and education in taste. This would-be "community" is premised on a curious affective dialectic that seeks to transform disgust for humanity into a pure movement of self-creation. The socio-political effects of this dialectic of disgust will be examined alongside Nietzsche's co-option of images of purity, in order to evaluate his response to modern nihilism. (shrink)

Our recent review demonstrates that “purity” is a messy construct with at least nine popular scientific understandings. Cultural beliefs about self-control help unify some of these understandings, but much messiness remains. The harm-centric theory of dyadic morality suggests that purity violations can be comprehensively understood as abstract harms, acts perceived by some people (and not others) to indirectly cause suffering.

In Purity and Danger, Douglas theorizes purity and impurity in terms of the instantiation and disruption of a shared symbolic order. Purity/impurity discourses act, according to Purity and Danger, as a homeostatic system which ensures the preservation of this social whole, generally encoding that which threatens social equilibrium as impurity. There have been calls for new social theory on this ‘under-theorized’ topic. Presenting such further reflections, I argue that Douglas’ account is less a full explanation than (...) a regularity. Representations of purity are only secondarily symbols of the social order. Rather, purity/impurity discourses are only associated with ‘matter out of place’ when phenomena are assessed for their relative deviation from an imputed state of ‘self-identity’: qualitative homogeneity and correspondence with their essence. Purity and impurity do more than judge self-identity, however. They can play a fundamental role in its performative construction; they are well adapted for smuggling assumptions into our discourses regarding the essence of particular phenomena and forms of subjectivity, simplifying a complex world into a stark contrast between the dangerous and the innocent, the valuable and the valueless, the necessary and the contingent, the originary and the prosthetic, the real and the apparent, and the unitary and the fragmented.

This paper discusses the phenomenon of ethical purity, namely, the complete orientation of the mind in an ethical direction and the absence of any element that detracts from this ethical orientation. It considers the way this phenomenon is presented in Confucian thought, through ideas such as cheng 誠， xu 虛， and jing 靜. The paper then approaches the phenomenon through a discussion of both the moral trials one goes through in life, and of the state of equanimity that accompanies (...) the purity of the mind. Finally, it concludes with a discussion of the nature of ethical purity, including the nature of moral progress and the oneness of the mind. -/- . (shrink)

How does gender affect work rewards for professionals in a state-run economy? Using surveys from physicians in Estonia in 1991, the authors first found that the gender of the physician did not affect the level of formal rewards. However, because the state allocated formal rewards on the basis of professional purity, which was negatively correlated with feminization, specialties that had the greatest proportion of women also had the lowest formal rewards. These findings contrast with the author's findings for the (...) level of informal “black market” rewards. Women were less likely to receive informal rewards than men, especially if they worked in subfields high in professional purity. The authors conclude that the link between professional purity and feminization is critical in explaining pay differences informal work rewards while gender itself is the critical factor in explaining informal reward differences.

Fitouchi et al. claim that seemingly victimless pleasures and nonproductive activities are moralized because they alter self-control. Their account predicts that: (1) victimless excesses are negatively moralized because they diminish self-control, and (2) restrained behaviors are positively moralized because they enhance self-control. Several examples run contrary to these predictions and call into question the general relationship between self-control and cooperation.

In her account of a debate held at Princeton University between herself and Peter Singer, the lawyer and disability rights activist Harriet McBryde Johnson criticizes the ‘terrible purity of Singer's vision’. Although she certainly disagrees with the substance of Singer's arguments concerning disability and infanticide, this remark is best understood as a critique of their form. In this paper, I attempt to make sense of this critique. I argue that Singer's characteristic mode of argument, with its appeal to a (...) universal, neutral point of view, makes it impossible for McBryde Johnson to give voice to her particular experience and thus obscures her humanity. In order to clarify the positive contribution that an appeal to particular experience may make to moral reasoning, I draw a parallel with the transformative effects of the experience of beauty, arguing that McBryde Johnson's writing ought to be regarded as both morally and philosophically instructive.

There are some people whose actions are much more often good than evil. If their infrequent immorality does not cause much harm, it is reasonable to regard such people as morally good. Nevertheless, moral goodness remains an elusive quality, because it is difficult to identify good actions. Motives, consequences, knowledge of alternatives and of the conventions prevailing in the context, the agent's history, character, and information all have a bearing on whether particular actions are good. These facts are not easy (...) to ascertain in any case, but when we are looking for a pattern formed of countless good actions over a lifetime, the difficulties are compounded. (shrink)

A proof of a theorem can be said to be pure if it draws only on what is 'close' or 'intrinsic' to that theorem. In this Element we will investigate the apparent preference for pure proofs that has persisted in mathematics since antiquity, alongside a competing preference for impurity. In Section 1, we present two examples of purity, from geometry and number theory. In Section 2, we give a brief history of purity in mathematics. In Section 3, we (...) discuss several different types of purity, based on different measures of distance between theorem and proof. In Section 4 we discuss reasons for preferring pure proofs, for the varieties of purity constraints presented in Section 3. In Section 5 we conclude by reflecting briefly on purity as a preference for the local and how issues of translation intersect with the considerations we have raised throughout this work. (shrink)

This article examines the foundation myths of Brazil in the last two centuries, paying particular attention to the relationship between these myths and governmental attitudes toward the hybridity of Northern and Southern ethnic and technoscientific entities.

Postcolonial science technology studies theories illuminate aspects of (...) this trajectory, but our analysis suggests a more complex scenario that involves internal political dynamics and the work of local intellectuals. We argue that the example of Brazilian social scientists should encourage scholars to go beyond the current focus on breaking the myths of technoscience and undertake mythmaking initiatives with wider societal resonances.

Pragmatic Genealogy involves constructing fictional, quasi-historical models in order to discover what might explain and justify our concepts, ideas or practices. It arguably originated with Hume, but its most prominent practitioners are Edward Craig, Bernard Williams and Mathieu Queloz. Its defenders allege that the method allows us to understand “what the concept does for us, what its role in our life might be” (Craig, 1990), and that this in turn can ground practical reasons to preserve or further a conceptual practice. (...) In this paper, I argue that none of this is true, and that only a turn to the actual recent history of such practices can reveal those sorts of practical reasons. (shrink)
