Wrestling with the Angel is a meditation on contemporary political, legal, and social theory from a psychoanalytic perspective. It argues for the enabling function of formal and symbolic constraints in sustaining desire as a source of creativity, innovation, and social change. The book begins by calling for a richer understanding of the psychoanalytic concept of the symbolic and the resources it might offer for an examination of the social link and the political sphere. The symbolic is a crucial dimension of (...) social coexistence but cannot be reduced to the social norms, rules, and practices with which it is so often collapsed. As a dimension of human life that is introduced by language--and thus inescapably "other" with respect to the laws of nature--the symbolic is an undeniable fact of human existence. Yet the same cannot be said of the forms and practices that represent and sustain it. In designating these laws, structures, and practices as "fictions," Jacques Lacan makes clear that the symbolic is a dimension of social life that has to be created and maintained and that can also be displaced, eradicated, or rendered dysfunctional. The symbolic fictions that structure and support the social tie are therefore historicizable, emerging at specific times and in particular contexts and losing their efficacy when circumstances change. They are also fragile and ephemeral, needing to be renewed and reinvented if they are not to become outmoded or ridiculous. Therefore the aim of this study is not to call for a return to traditional symbolic laws but to reflect on the relationship between the symbolic in its most elementary or structural form and the function of constraints and limits. McNulty analyzes examples of "experimental" (as opposed to "normative") articulations of the symbolic and their creative use of formal limits and constraints not as mere prohibitions or rules but as "enabling constraints" that favor the exercise of freedom. The first part examines practices that conceive of subjective freedom as enabled by the struggle with constraints or limits, from the transference that structures the "minimal social link" of psychoanalysis to constrained relationships between two or more people in the context of political and social movements. Examples discussed range from the spiritual practices and social legacies of Moses, Jesus, and Teresa of Avila to the political philosophy of Hannah Arendt and Jacques Rancière. The second part is devoted to legal and political debates surrounding the function of the written law. It isolates the law's function as a symbolic limit or constraint as distinct from its content and representational character. The analysis draws on Mosaic law traditions, the political theology of Paul, and twentieth-century treatments of written law in the work of Carl Schmitt, Walter Benjamin, Sigmund Freud, Pierre Legendre, and Alain Badiou. In conclusion, the study considers the relationship between will and constraint in Kant's aesthetic philosophy and in the experimental literary works of the collective Oulipo. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Commandment against the Law Writing and Divine Justice in Walter Benjamin’s “Critique of Violence”Tracy McNulty (bio)Pierre Legendre has shown that the Romano-canonical legal traditions that form the foundations of Western jurisprudence “are founded in a discourse which denies the essential quality of the relation of the body to writing” [“Masters of Law” 110]. It emerges historically as a repudiation of Jewish legalism and Talmud law, where (...) the rite of circumcision encodes the subject’s entry into law as an “allegiance to the absolute Writing,” or the “relationship between the human subject and the logical place of the Other” [110–11; see also “les juifs”]. In this shift, one understanding of writing is displaced by another: the material inscription of the letter, as an incommunicable limit or cut, is supplanted by the fantasy of what Legendre calls a “living writing,” a writing “in the heart” that promotes an ideal of perfect communication in which nothing is lost, in which meaning is lodged in an absolute Other who guarantees all knowledge. In his words, “we belong to a culture in which a mystically alienated human body stands in the place of the absolute book. The state has emerged from this structure.... Its basic characteristics can be set out by means of a fundamental Romano-pontifical maxim: the Emperor carries all the archives in his breast (omnia scrinia habet in pectore suo)” [“Masters of Law” 109].The ultimate theological source of this Roman maxim is Paul’s polemic against the Jewish law in the Epistle to the Romans. Paul’s polemic is structured by a distinction between two orders of law: the “law of God” and the “law of sin.” The first is associated with the intelligible “spirit” of the law, which is “written in the heart,” the second with the prescriptive “letter” of the Jewish law, which compromises or corrupts the first by binding it to a particular representation and consigning it to written form. Paul’s solution is to bypass the law, to bypass representation, and perhaps even language itself. The prescriptive “letter” of the Jewish law must be sublated by the law of the spirit, such that “we serve not under the old written code but in the new life of the Spirit” [Romans 7: 6]. Christ, as the living embodiment of the law of God, upholds the spirit of the law by “fulfilling”––and so rendering obsolete–its written form.The doctrine of Christ as the “living law” sustains what Legendre describes as a “banalisation of writing” [“Masters of Law” 111], a disregard for its material inscription that holds the letter to be nothing more than a placeholder, a flawed or incomplete representation of a meaning or truth that is itself beyond words. At the same time, it makes possible the legal and political fantasy of a living writing, located in a single body understood as the site of interpretive authority. The extraction of a meaning or truth from the intractable letter becomes the ultimate aim of the legal order and the most lofty task of its sovereign interpreter, uniquely charged with animating the dead letter. This notion permeates what Peter Goodrich describes as “the most standard protocols of legal reading,” according to [End Page 34] which “it is not the letter but the spirit that determines the meaning of the law”:The text is composed of dead letters (litera mortua); the rule is no more than a “mute judge,” a sleeping form, requiring the interposition, anima legis, of jurist or judge.... [T]he meaning of the law is internal to its living body, viva vox iuris or lex loquens, its image, interpreter, or legislator. In classical terms it is spelled out by reference to something beyond words: “to know the law is not to know the words of the law, but its force and power.” In a renaissance formulation we are similarly told that “no words, forms, niceties, or propriety of language is of any regard in the Civil Law, in comparison to truth, faithfulness and integrity. For verba menti, non verbis servire debet; words, are made as instruments to serve and express the mind, and not to command it.”[229–30]1... (shrink)

The evolution of the idea of hospitality can be traced alongside the development of Western civilization. Etymologically, the host is the “master,” but this identity is established through expropriation and loss—the best host is the one who gives the most, ultimately relinquishing what defines him as master. In The Hostess, Tracy McNulty asks, What are the implications for personhood of sharing a person—a wife or daughter—as an act of hospitality? In many traditions, the hostess is viewed not as (...) a subject but as the master’s property. A foreign presence that both sustains and undercuts him, the hostess embodies the interplay of self and other within the host’s own identity. Here McNulty combines critical readings of the Bible and Pierre Klossowski’s trilogy The Laws of Hospitality with analyses of exogamous marital exchange, theological works from the Talmud to Aquinas, the writings of Kant and Nietzsche, and the theory of femininity in the work of Freud and Lacan. Ultimately, she contends, hospitality involves the boundary between the proper and the improper, affecting the subject as well as interpersonal relations. Tracy McNulty is assistant professor of romance studies at Cornell University. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:diacritics 35.1 (2005) 71-98MuseSearchJournalsThis JournalContents[Access article in PDF]Hospitality after the Death of GodTracy McNultyPierre Klossowski's fiction has been only sporadically published in English, and largely dismissed as perverse erotica or soft-core porn. When his 1965 trilogy Les lois de l'hospitalité was partially translated in English (under the title Roberte, ce soir & The Revocation of the Edict of Nantes), its Library of Congress classification characterized it simply as "erotic (...) fiction—French." Even in France, Klossowski has become the very signifier of perversion. His artwork graces the cover of Serge André's L'imposture perverse and of numerous erotic novels, he has been "diagnosed" as a pervert by writers on both sides of the Atlantic, and unironic readers of his Sade mon prochain hail him as Sade's disciple and heir.1Admittedly, the larger stakes of Klossowski's work are easily obscured by its free adaptation of the stock themes of libertine literature. His fictional works, like his visual compositions (essentially representations of rape scenes, often on historical themes—Diana and Actaeon, the Rape of Lucretia), explore the conflict between a woman's chaste moral attitude and her gradual surrender to an assailant's advances. The Laws of Hospitality concerns the erotic awakening of "hospitality" in a woman, which exposes a contradiction within her moral character and reveals her symbolic identity to be without foundation. Its protagonist Octave, who bears more than a passing resemblance to his creator, is a collector of artworks that eroticize the moment of moral hesitation experienced by women submitting to the sexual advances of a chance stranger—or even a "spiritual" apparition. His "laws of hospitality" are the fruit of his desire to experience this operation firsthand; they name a practice wherein the master of the house "offers" his wife to fortuitous guests, in order to savor the moment of her surrender.However, the stakes of Klossowski's "perverse" meditations are very different from the Sadeian project of uprooting religious morality. Sade challenges the patriarchal and religious authorities of his day by demonstrating that the paternal signifier on which their laws are based is without foundation. In proving that the law cannot hold [End Page 71] up against the repeated assaults of libertinage, he mounts a systematic deconstruction of the symbolic order of language by the real of jouissance. But although Klossowski may share Sade's perverse drive to "humiliate the law with the object,"2 his target is not the signifier as such, but rather the imaginary consistency afforded by what he calls the "grammatical fiction of the 'I,'" the illusion of autonomous personhood. The "object" he confronts it with is not the natural "truth" of jouissance, but rather the feminine object who disrupts the identity of the "master" who offers her.Klossowski's reflections on the special status of femininity in Enlightenment culture—at once marginal and singularly "extimate"—have never been fully appreciated, despite their enormous interest for the study of culture. In a way unique among contemporary authors, Klossowski sheds light on Jacques Lacan's enigmatic insight that the cultural importance of the feminine object consists in its sublimated status as an "object raised to the dignity of the Thing" [Lacan 112]. His fiction underscores the close ties between the feminine and what Freud called das Ding, the Thing uncannily internal to subjectivity that Lacan later identified with the function of the Nebenmensch, as the apotheosis of the Christian idea of the prochain, or neighbor [Lacan 151–52].Although Klossowski's erotic scenario invites comparisons with Sade's and Fourier's utopian calls to dissolve the privative boundaries between subjects, what he understands by "hospitality" is not the abolition of personal identity, but rather the staging of its internal contradiction.Hospitality, at the Limits of the LawThe act of hospitality—whose theological and philosophical origins this former Dominican novice and Latin scholar was intimately acquainted with—concerns a very particular tension. Etymologically, the host is the "master," the one who "eminently personifies" identity: not only his own identity, but also that of the group in whose... (shrink)

This paper examines the recourse to mathematics as a “language of the real” in the literature of perversion and in the philosophical project of Alain Badiou.

As a drive to the inorganic, the death drive is fundamentally opposed to sensuality and, specifically, to pleasure and pain. This is why Gilles Deleuze understands Freud’s account of the death drive as the “beyond of the pleasure principle” not in terms of the transgression of a boundary or limit (going beyond pleasure into something painful or traumatic), but rather as a foray into speculative philosophy, an attempt to identify the transcendent principle or higher law of the pleasure principle, the (...) supersensual law of its sensual manifestations. This paper explores the construction of the supersensual reality of the death drive in masochistic fantasy and in fetishistic disavowal, exploring their affinity not only with art and aesthetics but with mathematical and formal constructions. Both help to elucidate Freud’s early insight that the death drive is more mathematical than physical, a purely immanent energy with no sensual manifestation. (shrink)

Although significant literature and jurisprudence has amassed on rights-based climate litigation over recent years, less research and case law has emerged on poverty-related court cases and the fulfilment of economic, social, and cultural rights (ESCR) in Canada. Fewer still are studies exploring the interlinkages between these areas of inquiry. The purpose of this paper is to explore, using Canada as a case study, rights-based developments in climate litigation cases and how these could impact the innovative advancement of ESCR (e.g. to (...) food, housing and water). Typically, issues of justiciability and standing emerge, impeding the realization of such rights. Given the grave threats we now face, climate cases and social movements must be brought together to better hold state actors accountable for their rights obligations. We implore the legal community to explore ways to traverse juridical obstacles to realize the interdependencies of human rights and protect the planet from calamitous climate change. (shrink)

Conscientious objection has become a divisive topic in recent bioethics publications. Discussion has tended to frame the issue in terms of the rights of the healthcare professional versus the rights of the patient. However, a rights-based approach neglects the relational nature of conscience, and the impact that violating one’s conscience has on the care one provides. Using medical assistance in dying as a case study, we suggest that what has been lacking in the discussion of conscientious objection thus far is (...) a recognition and prioritising of the relational nature of ethical decision-making in healthcare and the negative consequences of moral distress that occur when healthcare professionals find themselves in situations in which they feel they cannot provide what they consider to be excellent care. We propose that policies that respect the relational conscience could benefit our healthcare institutions by minimising the negative impact of moral distress, improving communication among team members and fostering a culture of ethical awareness. Constructive responses to moral distress including relational cultivation of moral resilience are urged. (shrink)

The work of Alain Badiou attempts to refound the project of Western philosophy by returning to the platonic celebration of mathematics as the basis for any transmissible knowledge. In “The New Man's Fetish,” Tracy McNulty shows that Badiou's return to Plato is secretly mediated by the French libertine tradition. Badiou derives the militant figure of mathematics less from Plato than from Lautréamont—in whose “Songs of Maldoror” she (mathematics) appears as a stern mistress. Reading McNulty, within the framework (...) of psychoanalytic debates around the clinic of perversion, I show that McNulty's emphasis upon this mediation, despite appearances, functions less to undermine the authority of Badiou's philosophical project than to raise the stakes of perversion. Taking Badiou's libertinism seriously makes it possible to grasp how perversion strives to formalize the death drive and thus to open politics and philosophy to the future. At the same time, McNulty shows that Badiou's theory of number makes it possible to rethink the distinctions between number, trope, figure, and fetish; and thus to reopen a discussion of the relationships between philosophy, psychoanalysis, and literature.

Foundational theories of mental content seek to identify the conditions under which a mental representation expresses, in the mind of a particular thinker, a particular content. Normativists endorse the following general sort of foundational theory of mental content: A mental representation r expresses concept C for agent S just in case S ought to use r in conformity with some particular pattern of use associated with C. In response to Normativist theories of content, Kathrin Glüer-Pagin and Åsa Wikforss propose a (...) dilemma, alleging that Normativism either entails a vicious regress or falls prey to a charge of idleness. In this paper, I respond to this argument. I argue that Normativism can avoid the commitments that generate the regress and does not propose the sort of explanation required to charge that its explanation has been shown to be problematically idle. The regress-generating commitment to be avoided is, roughly, that tokened, contentful mental states are the product of rule-following. The explanatory task Normativists should disavow is that of explaining how it is that beliefs and other contentful mental states are produced. I argue that Normativism, properly understood as a theory of content, does not provide this kind of psychological explanation, and therefore does not entail that such explanations are to be given in terms of rule-following. If this is correct, Normativism is not the proper target of the dilemma offered by Glüer-Pagin and Wikforss. Understanding why one might construe Normativism in the way Glüer-Pagin and Wikforss must, and how, properly understood, it avoids their dilemma, can help us to appreciate the attractiveness of a genuinely normative theory of content and the importance of paying careful attention to the sort of normativity involved in norm-based theories of content.

We are told the academic ideal is that all voices have equal claim to attention. But this excludes the voices of the poor and marginalized, who lack theresources to be heard. They are the victims of historical forces over which they have no control, while a kind of “economic fundamentalism” infects first-worldattitudes toward markets and free trade, widely viewed as capable of automatically solving the problems of the Third World. But the earth does not possess theresources to allow everyone to (...) enjoy a first-world standard of living. We can help only those with whom we share moral community. The issue is the recognition ofthe other as a fellow human. Taking the victims’ side, modeling the world from the perspective of the reality that daily oppresses them, transforms both the victimsand ourselves. This change in perspective will not be easy. The movement from observer to participant in the struggle of the poor cannot help changing the waywe relate to our students and what we understand by “education.”. (shrink)

In this paper we consider the prospects for an account of good argument that takes the character of the arguer into consideration. We conclude that although there is much to be gained by identifying the virtues of the good arguer and by considering the ways in which these virtues can be developed in ourselves and in others, virtue argumentation theory does not offer a plausible alternative definition of good argument.

The concept of nihilism plays an interesting role in Richard Rorty's oeuvre. On the one hand, Rorty barely refers to the concept; on the other, Rorty's critics pejoratively characterize his pragmatism as nihilistic. This chapter seeks to clarify Rorty's position. It suggests that Rorty avoids the concept in order to get away from the conceptual baggage that accompanies the existential sense of the term. Rorty neither endorses the idea that human lives are meaningless nor thinks that abandoning the Platonic quest (...) for truth diminishes our capacity to experience meaningful lives. By challenging these assumptions, Rorty can then be seen as a thinker who may have much more to say about the modern challenges to human meaning than meets the eye. In this light, the chapter presents three cases that explore Rorty's contributions to our understanding of existential nihilism. It also suggests contemporary research approaches to Rorty and nihilism. (shrink)

How did Baruch Spinoza, the seventeenth-century Dutch-Jewish philosopher, become a nineteenth-century German Marxist? It is on its face an unlikely development. Karl Marx was a fiery revolutionary theorist who heralded the imminent demise of capitalism, while Spinoza was a contemplative philosopher who preached rational understanding and voiced skepticism about open rebellion. Further, Spinoza criticized all teleological ideas as anthropomorphic fantasies, while Marxism came to be associated expressly with teleological historical development. Yet socialists of the German nineteenth century were consistently drawn (...) to Spinoza as their philosophical guide. Tracie Matysik shows how the metaphorical meeting of Spinoza and Marx arose out of an intellectual conundrum about the meaning of activity. How is it, exactly, that humans can be fully determined creatures - creatures in nature and governed by causal laws of nature - and also able to change their world? To address this seeming paradox, many revolutionary theorists scrapped the idea of activity as something autonomous humans do when they assert themselves against nature and its causal laws. Thinking with Spinoza, they came to think of activity instead as relating - as the state of relations between humans and between humans and the non-human world. Matysik follows these Spinozist-socialist intellectual experiments in the meaning of activity that unfolded across the nineteenth century, drawing lessons from them that may be meaningful for the environmental-justice issues confronting the contemporary world.

Although many of the congenital syndromes that used to be lethal no longer are, they are still routinely referred to as “lethal anomalies.” But the label is not only inaccurate, it is also dangerous: by portraying as a medical determination what is in fact a judgment about the child's quality of life, it wrests from the parents a decision that only the parents can make.

This paper explores a philosophical praxis of paying attention, and the importance of bodily comportment, in human-animal interactions. It traces some of the beginnings of the notion of attentiveness as it has arisen in contemporary Western environmental and animal ethics, and its further development into both a philosophical approach and actual practice as a kind of interspecies etiquette. It is informed by the kinds of comportments of openness and responsivity found in diverse examples of practical phenomenology. Through a wide-ranging interdisciplinary (...) discussion, I suggest that a praxis of attentiveness can inspire practical applications of ethical interactions between species. (shrink)

A popular approach to defining fictive utterance says that, necessarily, it is intended to produce imagining. I shall argue that this is not falsified by the fact that some fictive utterances are intended to be believed, or are non-accidentally true. That this is so becomes apparent given a proper understanding of the relation of what one imagines to one's belief set. In light of this understanding, I shall then argue that being intended to produce imagining is sufficient for fictive utterance (...) as well. (shrink)

A common view in both philosophy and the vision sciences is that, in human vision, wavelength information is primarily ‘for’ colouring: for seeing surfaces and various media as having colours. In this article we examine this assumption of ‘colour-for-colouring’. To motivate the need for an alternative theory, we begin with three major puzzles from neurophysiology, puzzles that are not explained by the standard theory. We then ask about the role of wavelength information in vision writ large. How might wavelength information (...) be used by any monochromat or dichromat and, finally, by a trichromatic primate with object vision? We suggest that there is no single ‘advantage’ to trichromaticity but a multiplicity, only one of which is the ability to see surfaces and so on as having categorical colours. Instead, the human trichromatic retina exemplifies a scheme for a general encoding of wavelength information given the constraints imposed by high spatial resolution object vision. Chromatic vision, like its partner, luminance vision, is primarily for seeing. Viewed this way, the ‘puzzles’ presented at the outset make perfect sense. 1 Reframing the Problem1.1 Introduction1.2 Three puzzles1.2.1 Why is trichromatic vision an anomaly in diurnal mammals?1.2.2 Why does the colour system occupy such a large and central part in human vision?1.2.3 Why are the blue cones so rare?1.3 Recasting the question2 The Costs and Benefits of Spectral Vision2.1 Spectral information and object vision2.2 Encoding the spectral dimension of light2.2.1 ‘General’ versus ‘specific’ encoding2.2.2 Spectral encoding and the monochromat2.2.3 Spectral encoding and the dichromat2.2.4 Spectral encoding and the human trichromat2.3 Three puzzles revisited2.3.1 Why is trichromatic vision an anomaly in diurnal mammals?2.3.2 Why does the colour system occupy such a large and central part in human vision?2.3.3 Why are the blue cones so rare3 Conclusion.
