Modern scientific theories of emotional behavior, almost without exception, trace their origin to Charles Darwin, and his publications On the Origin of Species (1859) and The Expression of the Emotions in Man and Animals (1872). The most famous evolutionary dilemma Darwin acknowledged as a challenge to his theory of natural selection was the incomplete sub Cambrian fossil record. However, Darwin struggled with two other rarely referenced theoretical and scientific dilemmas that confounded his theories about emotional behavior. These included (1) the (...) origin of social instincts (e.g., altruism, empathy, reciprocity and cooperation) and the reasons for their conservation in evolution and (2) the peripheral control of heart rate vis-a-vis emotional behavior outside of consciousness. Darwin acknowledged that social instincts are critical to the survival of some species, but had difficulty aligning them with his theory of natural selection in humans. Darwin eventually proposed that heart rate and emotions are controlled via one’s intellect and cortical mechanisms, and that instinctive behavior is genetically-programmed and inherited. Despite ongoing efforts, these two theoretical dilemmas are debated to this day. Simple testable hypotheses have yet to emerge for the biological mechanisms underlying instinctive behavior or the way heart rate is controlled in infants. In this paper, we review attempts to resolve ¬these issues over the past 160 years. We posit that research and theories that supported Darwin’s individualistic brain-centric and genetic model have become an “orthodox” Western view of emotional behavior, one that produced the prevailing behavioral construct of attachment as developed by John Bowlby. We trace research and theories that challenged this orthodoxy at various times, and show how these challenges were repeatedly overlooked, rejected, or misinterpreted. We review two new testable theories, emotional connection theory and calming cycle theory, which we argue resolve the two dilemmas We show emerging scientific evidence from physiology and a wide variety of other fields, as well from clinical trials among prematurely born infants, that supports the two theories. Clinical implications of the new theories and possible new ways to assess risk and intervene in emotional, behavioral and developmental disorders are discussed. (shrink)

We have previously proposed that mothers and infants co-regulate one another’s autonomic state through an autonomic conditioning mechanism, which starts during gestation and results in the formation of autonomic socioemotional reflexes following birth. Theoretically, autonomic physiology associated with the ASR should correlate concomitantly with behaviors of mother and infant, although the neuronal pathway by which this phenomenon occurs has not been elucidated. In this paper, we consider the neuronal pathway by which sensory stimuli between a mother and her baby/child affect (...) the physiology and emotional behavior of each. We divide our paper into two parts. In the first part, to gain perspective on current theories on the subject, we conduct a 500-year narrative history of scientific investigations into the human nervous system and theories that describe the neuronal pathway between sensory stimulus and emotional behavior. We then review inconsistencies between several currently accepted theories and recent data. In the second part, we lay out a new theory of emotions that describes how sensory stimuli between mother and baby unconsciously control the behavior and physiology of both. We present a theory of mother/infant emotion based on a set of assumptions fundamentally different from current theories. Briefly, we propose that mother/infant sensory stimuli trigger conditional autonomic socioemotional reflexes, which drive cardiac function and behavior without the benefit of the thalamus, amygdala or cortex. We hold that the ASR is shaped by an evolutionarily conserved autonomic learning mechanism that forms between mother and fetus during gestation and continues following birth. We highlight our own and others research findings over the past 15 years that support our contention that mother/infant socioemotional behavior is driven by mutual autonomic state plasticity, as opposed to cortical trait plasticity. We review a novel assessment tool designed to measure the behaviors associated with the ASR phenomenon. Finally, we discuss the significance of our theory for the treatment of mothers and infants with socioemotional disorders. (shrink)

The subject of (ir)reducibility in biochemistry has resurfaced recently in the literature. Along with it comes a renewed emphasis on the organizational complexity of the living state and, more broadly, concern over the unity of the sciences.

We have conducted an experimental study of V-type electromagnetically induced transparency in sodium. Its principles are elucidated by a simple model. Measurements show decreased fluorescence and absorption depending on the detuning of the driving and probe fields, which is in agreement with the results of numerical simulation.

Scholars of classical philosophy have long disputed whether Aristotle was a dialectical thinker. Most agree that Aristotle contrasts dialectical reasoning with demonstrative reasoning, where the former reasons from generally accepted opinions and the latter reasons from the true and primary. Starting with a grasp on truth, demonstration never relinquishes it. Starting with opinion, how could dialectical reasoning ever reach truth, much less the truth about first principles? Is dialectic then an exercise that reiterates the prejudices of one's times and at (...) best allows one to persuade others by appealing to these prejudices, or is it the royal road to first principles and philosophical wisdom? In From Puzzles to Principles? May Sim gathers experts to argue both these positions and offer a variety of interpretive possibilities. The contributors' thoughtful reflections on the nature and limits of dialectic should play a crucial role in Aristotelian scholarship. (shrink)

This is the first anthology to take a theoretical look at violence against women. Each essay shows how philosophy provides a powerful tool for examining a difficult and deep-rooted social problem. Stanley G. French, Wanda Teays, and Laura M. Purdy, all philosophers, present a familiar phenomenon in a new and striking fashion. The editors employ a two-tiered approach to this vital issue. Contributors consider both interpersonal violence, such as rape and battering; and also systemic violence, such as sexual harassment, pornography, (...) prostitution, and violence in a medical context. The editors have further broadened the discussion to include such cross-cultural issues as rape in war, dowry deaths, female genital mutilation, and international policies on violence against women. Against this wide range of topics, which integrate personal perspectives with the philosophical, the contributors offer powerful analyses of the causes and effects of violence against women, as well as potential policies for effecting change.

This book's importance is derived from three sources: careful conceptualization of teacher induction from historical, methodological, and international perspectives; systematic reviews of research literature relevant to various aspects of teacher induction including its social, cultural, and political contexts, program components and forms, and the range of its effects; substantial empirical studies on the important issues of teacher induction with different kinds of methodologies that exemplify future directions and approaches to the research in teacher induction.

Moral distress (MD) is well-documented within the nursing literature and occurs when constraints prevent a correct course of action from being implemented. The measured frequency of MD has increased among nurses over recent years, especially since the COVID-19 Pandemic. MD is less understood among nurse leaders than other populations of nurses. A qualitative systematic review was conducted with the aim to synthesize the experiences of MD among nurse leaders. This review involved a search of three databases (Medline, CINAHL, and APA (...) PsychINFO) which resulted in the retrieval of 303 articles. PRISMA review criteria guided authors during the article review and selection process. Following the review, six articles were identified meeting review criteria and quality was assessed using the Critical Appraisal Skills Programme (CASP) Checklist for qualitative studies. No ethical review was required for this systematic review. The six studies included in this review originated from the United States, Brazil, Turkey, and Iran. Leadership roles ranged from unit-based leadership to executive leadership. Assigned quality scores based upon CASP criteria ranged from 6 to 9 (moderate to high quality). Three analytical themes emerged from the synthesis: (1) moral distress is consuming; (2) constrained by the system; and (3) adapt to overcome. The unique contributors of MD among nurse leaders include the leadership role itself and challenges navigating moral situations as they arise. The nurse leader perspective should be considered in the development of future MD interventions. (shrink)

Recent neuroimaging studies of language processing are examining the neural substrate of phonology because of its critical role in mapping sound information onto higher levels of language processing (e.g., words) as well as providing codes in which verbal information can be temporarily stored in working memory. However, the precise role of the inferior frontal cortex in spoken and written phonological tasks has remained elusive. Although lesion studies have indicated the presence of selective deficits in phonological processing, the location of lesions (...) underlying these impairments has not revealed a consistent pattern. Despite efforts to refine methods and tasks, functional neuroimaging studies have also revealed variability in activation patterns. Reanalysis of evidence from these neuroimaging studies suggests that there are functional subregions within the inferior frontal gyrus that correspond to specific components of phonological processing (e.g., orthographic to phonological conversion in reading, and segmentation in speech).

Calgary, Alberta: U of Calgary P, 1999. Pp. 279. NP. These three books, all published within the last five years, are both reflections of and important contributions to the growing scholarship on women's roles in rhetorical history as theorists and as practitioners. Indeed, the titles listed in chronological order--Reclaiming Rhetorica, Listening to Their Voices, and The Changing Tradition--suggest the process of transformation that the study of rhetorical history has undergone in recent years. Both individually and together, these works are a healthful antidote to the rhetorical history most of us learned at our (male) professors' knees.The books share certain features. As edited volumes, they span rhetorical history, from its classical roots to modern feminist theories. Although some figures appear more than once in different volumes (e.g., Aspasia and Mary Astell), the constraints of brief chapters permit us only tantalizing glimpses of each woman and her activities. Like all edited collections, these books include a variety of viewpoints and voices. Despite the disparity that is inevitable in a collection of essays, the quality of the work in these volumes is uniformly high. The editors of all three collections have done a nice job of assuring that the contributors stay to the point and write well without sacrificing scholarly precision. For those seeking a simple history or detailed analysis of any particular figure or time, these books will not suffice. But for most readers who are unfamiliar with the full range [End Page 294] of women in rhetorical history, this reader among them, these volumes provide a delightful introduction to the resilience, creativity, and significance of women in our formerly unacknowledged rhetorical past.In her introduction to Reclaiming Rhetorica, Andrea Lunsford shares the intriguing history of the volume, which explains its eclecticism and its goals. Approached by students who wanted to explore the role of women in rhetorical history, Annette Kolodny offered a two-semester graduate seminar titled "Women Rhetoricians." For the class, the students did extensive archival recovery research, much of which is included in the published volume. Interestingly, the students were the ones who persisted in trying to bring their works, plus the other contributors' efforts, to publication. The resultant book is, then, as James J. Murphy says in his foreword, "not a history of women rhetoricians, or women orators, or women writers. It is, instead, a glimmer of possibilities, an array of glances,--an enthymeme."The essays range widely in time covered and in focus. For example, the first chapter is a consideration of Aspasia, who left no written record of her own. Her accomplishments and influence must, then, be constructed from references to her in the works of others. The authors, Susan Jarratt and Rory Ong, contend that both her gender and her non-Athenian roots played a role in the suppression of her memory. Returning to the theme of "dangerous femininity," the concluding chapter explores the work of a modern theorist, Julia Kristeva. In that chapter, Suzanne Clark demonstrates how Kristeva has challenged traditional notions of rhetoric and provides dialogism as an antidote to the constraints of earlier approaches to human interaction. The chapters between these two take a variety of directions. Mary Wollstonecraft's feminist dialogics stands alongside of the autobiographical The... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The View from Pȏle NordSartre, Beauvoir, and Girard on Mimesis, Embodiment, and DesireMartha J. Reineke (bio)Simone Beauvoir's novel She Came to Stay immerses readers in a 1930s Parisian social scene, thanks in part to the character Françoise. Eavesdropping with Françoise on a man and woman seated at a table in the Pȏle Nord café, readers of the novel hear the woman confide, "I've never been able to follow the (...) rules of flirting. I have a morbid horror of being touched."1 As Françoise invites us to turn our gaze toward another couple seated nearby, we observe a possible instance of the very discomfort to which the first woman has attested. A hapless female looks "uncertainly at a man's huge (grosse) hand that has just pounced on hers (s'abattre sur)."2 Of these two scenes from She Came to Stay, Jean-Paul Sartre memorializes only the second.3 As described by Sartre in Being and Nothingness, a man and a woman on their first date are seated at a table. The man "takes" (prend) the hand of a woman and holds it between "his warm hands" (les mains chaudes) while the woman makes her hand inert, even as she "permits herself to enjoy his desire."4 Thanks to the pervasive influence of Being and Nothingness on the philosophical canon, the disquieting scene Françoise describes in She Came to Stay largely has been forgotten. Sartre sets the [End Page 1] terms for the unfortunate woman's ongoing life: She is a paradigm of "bad faith." Two decades later, her immortality is secured by René Girard: The woman is a prime exemplar of coquetry, a "fundamental" concept in the development of Girard's theory of mimetic desire.5In the wake of today's #metoo headlines, we may find ourselves eager to weigh in anew on the scene at Pȏle Nord. Are we witnesses to flirtation? Seduction? Unwanted sexual attention? Debates about coercion and guile, predators and prey, are unlikely to be productive; after all, Girard has advised that participants in such debates flounder in a problematic victimology.6 Nevertheless, Sartre and Girard's fascination with the mise en scène at Pȏle Nord warrants reexamination on other grounds. Sartre's discussion of the young woman beset by bad faith in Being and Nothingness is one of several instances in which Sartre is shown exerting a significant influence on Girard. Focusing closely on these occurrences, we can identify features of Sartrian existentialism that contribute constructively to the development of Girard's thought. So also can we uncover a problematic view of the body in mimetic theory. Girard shares with Sartre a profound ambivalence toward embodiment. An alternative perspective visible in Beauvoir's writing could enhance the treatment of the body and eroticism in mimetic theory.Girard's early work attests to Sartre's influence. Writing in Evolution of Desire, Cynthia Haven introduces the topic of Sartre's impact on Girard by recounting Parisian intellectuals' responses to tensions between Camus and Sartre: "Everyone took one side or the other." Girard's friends reported that Girard "was on the Sartre side."7 In an interview with Rebecca Adams, Girard states that "I was influenced by Sartre and Camus, like other people of my generation, especially by Sartre."8 Girard acknowledges Sartre's influence in several other contexts. In a 2007 interview with Pierpaolo Antonello, Girard recalls his early philosophical interests: "… From Sartre I went to Merleau-Ponty and all the authors related to phenomenology, which fascinated me and for a while I wanted to write in the phenomenological style."9 Commenting in the 2008 preface to La Conversion de l'art, Girard states that he is struck by the Sartrian "tone" of his own writing.10 Scholarly explorations of the specifics of the influence of Sartre on Girard have cataloged the most important Sartrian concepts: a lack of being, the in-itself/for-itself (en-soi/pour-soi); the "projet"; patterns of desire (e.g., masochism and sadism), and bad faith.11 These themes are discussed in what follows, with special attention to Girard and Sartre's perspectives on human...

In lieu of an abstract, here is a brief excerpt of the content:The Touching TestAI and the Future of Human IntimacyMartha J. Reineke (bio)Each Friday, the New York Times publishes Love Letters, a compendium of articles on courtship. A recent story featured Melinda, a real estate agent, and Calvin, a human resources director.1 They had met at a market deli counter. On their first date, a lasagna dinner at Melinda's home, Calvin posed the question, "What are you looking for in (...) a man?" To his surprise, Melinda reached into her pocket and pulled out a two-page list, "Melinda's Husband Traits." Her 46-item list begins with "Christian, honor God, put Him first" and includes as entry number 37, "He likes to be touched and likes to touch me." Notwithstanding laudable features of Melinda's inventory, if David Levy, President of the International Computer Games Association and an expert on artificial intelligence (AI), is correct in his predictions, in the years ahead, women like Melinda who know exactly what they are looking for in a husband will desire something radically new: a robot. After all, artificial agents will soon possess or improve on every quality the romantically inclined previously have sought in a human partner. [End Page 123]Levi predicts robots will be preferred romantic partners by the middle of this century.2 Capable of providing erotic satisfaction and creating deep emotional bonds with human partners, these robots will be an achievable outcome of AI engineering that already has brought to market industrial and service robots, virtual pets, and caregiver robots for the elderly. Levi offers a research-based inventory of traits a robot will offer its human partner: kindness and understanding, a sense of humor, expressiveness, intelligence, and sociability.3 He pinpoints additional features that will facilitate romance: The ideal robot partner will elicit erotic attraction, give evidence of readiness for a serious relationship with its verbal assertions, and possess a capacity for mutual intimacy.4 Levi's argument is intentionally provocative, for he emphasizes the centrality of sex to future robot/human pairings, waxing rhapsodic about the performative superiority of robots to humans in the sexual act.5Elaborating on potential human love relationships with robots, Levi asserts that a robot will need to master imitation if a human is to want it as a romantic partner. Not only is imitation a central aspect of every human-to-human relationship, but also imitation has been identified by researchers as a crucial element in romantic desire.6 Levi states that human-to-human attraction is founded on similarities between prospective partners in appearance, personality, and social context. It is sustained only through what Levi calls "reciprocal liking."7 For romantic relationships between humans and robots to flourish, they too must engage in acts of reciprocal imitation.In highlighting the necessity of imitation in effective robot and human interactions, Levi draws close to René Girard's theory of "mimetic desire." According to Girard, imitation structures all "wanting,"8 delineating what we aspire to look like or hope to possess and determining what we value, take comfort in, or experience as a threat. Indeed, the individual is never the origin point of its desires. Each of us always desires mimetically—according to the desire of the other.9 As Scott Garrels confirms in Mimesis and Science, researchers studying imitation in developmental, comparative, and social psychology, as well as in neurophysiology and cognitive neuroscience, support Girard's claims: Imitation is fundamental in human life.10 Likewise, Girard concurs with Levi that romantic relationships are primary examples of imitative desire. As described by Girard in Deceit, Desire, and the Novel, imitative behaviors form the romantic triangles that feature prominently in fiction: for example, Odette and the many men enchanted by her in Proust's In Search of Lost Time; Anselmo, Lotario, and Camilla in Don Quixote; and Velchaninov and Troussotzki, along with Troussotzki's deceased wife and prospective fiancée, in Dostoyevsky's The Eternal Husband.11 [End Page 124]Notwithstanding similarities in Levi and Girard's views of imitation, they differ in a crucial respect. Only Girard acknowledges just how extraordinarily fraught mimesis can become. When imitators compete (e.g., for things, status, and experiences), they will contest... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:MIMETIC VIOLENCE AND NELLA LARSEN'S PASSING: TOWARD A CRITICAL CONSCIOUSNESS OF RACISM Martha Reineke University ofNorthern Iowa In her recent essay, "Working through Racism: Confronting the Strangely Familiar," Patricia Elliot proposes that members of dominant groups who want to contest racism1 not only challenge economic, political, and social processes within society that produce racism, but also address personal claims they make on institutional structures which help to maintain (...) it (63). Sympathetic with an anti-racist strategy that concerns itself not only with racism at the institutional level but also with racism on a more intimate scale, Elliot nevertheless laments that individual complicity in racism is frequently attributed to aproblematic attitude. As a consequence, anti-racist work among members of dominant groups often is arrayed along a narrow spectrum: in workshops or in-service seminars participants attempt to identify and acknowledge biased and discriminatory views. Elliot fears that consciousness-raising efforts ofthis kind are unlikely to effect social change ifthose who participate continue to favor the confessional stance. Urging her readers to develop a "critical consciousness," a concept she takes from bell hooks (hooks 118), Elliot asks that members ofdominant groups who desire to promote social change not only combat institutional racism, but also divest themselves oisubjective investments in racism (63). Only as persons commit 1 Racism "involves the subordination ofpeople ofcolor by white people" (Rothenberg 6). Marked by discrimination and prejudice, racism entails also the exercise ofpower (conscious and unconscious, intentional and unintentional) by which white people maintain positions of privilege over persons ofcolor (Rothenberg 7). Martha Reineke75 themselves to a sophisticated and nuanced analysis of white complicity in structures of domination in order to grapple with racism at multiple levels—includingidentityformation, maintenance, and transformation—can members ofdominant groups actually tackle and begin to dismantle it (Elliot 63). Elliot's call to critical consciousness is laudable, but the goal she sets forth is not easily attained. As 1 struggle to achieve hook's critical consciousness of racism, like Elliot (64), I find difficult the task ofexploring the construction ofmy own identity as a white academic.2 For example, when I discuss issues in women's lives in the classroom or at professional conferences, I not infrequently am challenged by women of color who note that unexamined privilege (race and class) skews my perspective.3 1 also find myselfspeaking for others, assuming their voices, when I should speak only for myself. As a consequence, I regularly have cause to ponder whether, under the guise of contributing to anti-racistwork, I am appropriating others' voices in ways that reinforce racism rather than challenge it. For instance, on what grounds do I, a white woman, in this essay propose to address the problem of racism by reflecting on a novella written by an African-American woman? Does white privilege foreground my choice, precluding me from reading a work of literature in ways that might challenge rather than further racism? Grappling with these issues while reflecting on the theme of a critical consciousness ofracism, I find instructive the Girardian notion of mimesis. The dynamics of mimesis account well for agents of racism who, simultaneously recognizing and denying difference, act in ways that inhibit social and subjective transformation. Were members ofdominant groups to 2 Ofcourse, a professional affiliation is only one facet ofone's identity. I focus on that facet here because, through conversations with students about literature, I seek to contribute to antiracist work. 3Recent publications record similar conversations among women ofcolor and white women about white privilege. In White Women, RaceMatters: The Social Construction ofWhiteness, Ruth Frankenberg offers an ethnographic analysis ofthe dynamics ofprivilege in white women's lives. In The Color ofPrivilege: Three Blasphemies on Race andFeminism, Aída Hurtado offers a reflexive theory ofgender subordination which focuses on unwritten rules, inclusive of daily practices and psychological processes, that maintain power for whites as a group.

The essays in this volume were written to celebrate the sixtieth birthday of G. E. L. Owen, who by his essays and seminars on ancient Greek philosophy has made a contribution to its study that is second to none. The authors, from both sides of the Atlantic, include not only scholars whose main research interests lie in Greek philosophy, but others best known for their work in general philosophy. All are pupils or younger colleagues of Professor Owen who are indebted (...) to his practice of philosophical scholarship as a first-order philosophical activity. At the heart of G. E. L. Owen's work has been a preoccupation with the role of philosophical reflection on language in the metaphysics and epistemology of Plato, Aristotle and other ancient Greek thinkers. This is accordingly the general topic of the present volume, which includes five papers on Plato's critical dialogues and seven on Aristotle, prefaced by two on Heraclitus and followed by a study of the debate in Hellenistic philosophy on the sorites. This is a book for specialists in Greek philosophy and philosophers of language which will also be of interest to some linguists. (shrink)

If □ is conceived as an operator, i.e., an expression that gives applied to a formula another formula, the expressive power of the language is severely restricted when compared to a language where □ is conceived as a predicate, i.e., an expression that yields a formula if it is applied to a term. This consideration favours the predicate approach. The predicate view, however, is threatened mainly by two problems: Some obvious predicate systems are inconsistent, and possible-worlds semantics for predicates of (...) sentences has not been developed very far. By introducing possible-worlds semantics for the language of arithmetic plus the unary predicate □, we tackle both problems. Given a frame (W, R) consisting of a set W of worlds and a binary relation R on W, we investigate whether we can interpret □ at every world in such a way that □ $\ulcorner A \ulcorner$ holds at a world ᵆ ∊ W if and only if A holds at every world $\upsilon$ ∊ W such that ᵆR $\upsilon$ . The arithmetical vocabulary is interpreted by the standard model at every world. Several 'paradoxes' (like Montague's Theorem, Gödel's Second Incompleteness Theorem, McGee's Theorem on the ω-inconsistency of certain truth theories, etc.) show that many frames, e.g., reflexive frames, do not allow for such an interpretation. We present sufficient and necessary conditions for the existence of a suitable interpretation of □ at any world. Sound and complete semi-formal systems, corresponding to the modal systems K and K4, for the class of all possible-worlds models for predicates and all transitive possible-worlds models are presented. We apply our account also to nonstandard models of arithmetic and other languages than the language of arithmetic. (shrink)

This study investigated the roles of problem structure and strategy use in problem encoding. Fourth‐grade students solved and explained a set of typical addition problems (e.g., 5 + 4 + 9 + 5 = _) and mathematical equivalence problems (e.g., 4 + 3 + 6 = 4 + _ or 6 + 4 + 5 = _ + 5). Next, they completed an encoding task in which they reconstructed addition and equivalence problems after viewing each for 5 s. Equivalence problems (...) of the form 4 + 3 + 6 = 4 + _ overlap with a perceptual pattern found in traditional arithmetic problems (i.e., answer blank in final position), and students' encoding was poorest on problems of this type. Individual differences in encoding the equivalence problems were related to variations in strategy use. Some students solved blank‐final equivalence problems using the standard arithmetic strategy of performing all given operations on all given numbers. These students made more errors in encoding problem structure, but fewer errors in encoding the numbers, than did students who solved the problems using correct or other incorrect strategies. Moreover, students who expressed many strategies for solving the blank‐final equivalence problems made fewer errors in encoding problem structure, but more errors in encoding the numbers, than did students who expressed only a single strategy. Results highlight that encoding is intended to guide action and that prior experience can simultaneously facilitate and interfere with accurate encoding. (shrink)

It is shown that the determinacy of $G_{\delta \sigma }$ games of length $\omega ^2$ is equivalent to the existence of a transitive model of ${\mathsf {KP}} + {\mathsf {AD}} + \Pi _1\textrm {-MI}_{\mathbb {R}}$ containing $\mathbb {R}$. Here, $\Pi _1\textrm {-MI}_{\mathbb {R}}$ is the axiom asserting that every monotone $\Pi _1$ operator on the real numbers has an inductive fixpoint.

PurposeThe purpose of this paper is to explore a particular philosophical underpinning for Information Systems (IS) research – critical systemic thinking (CST). Drawing upon previous work, the authors highlight the principal features of CST within the tradition of critical research and attempt to relate it to trends in the Italian school of IS research in recent years, as exemplified by the work of Claudio Ciborra but also evident in work by, e.g. Resca, Jacucci and D'Atri.Design/methodology/approachThis is a conceptual paper which (...) explores CST, characterised by a focus on individual uniqueness, and socially‐constructed, individual worldviews as generators of human knowing.FindingsThe paper draws on work by Heinz Klein in which he elaborated three constitutive stages in critical research: interpretive, genealogical and constructive. The authors introduce a fourth, reflective stage and discuss five categories of critical research, reflecting different perspectives on emancipation, culminating in emergent expressionism, associated with Ciborra and the Italian school more generally.Research limitations/implicationsThis paper discusses approaches to CST and how they might have practical implications in IS development. The distinction between approaches founded in logical empiricism and those founded in hermeneutic dialectics are considered and the development of critical and systems strands are discussed.Practical implicationsThe paper addresses CST as an approach to development of information systems. Such approaches enable users to explore their individually unique understandings and create a constructive dialogue with one another, which emancipates and empowers users to own and control their own development processes and hence build more productive and usable systems.Social implicationsA focus on research which is oriented towards emancipation in the tradition of critical social theory.Originality/valueThe paper draws on extensive theoretical research carried out by the authors over a period of more than ten years in CST and synthesises the practical implications.
