Philosophers in the phenomenological tradition have emphasised the relationship between temporality and various central aspects of subjectivity, including consciousness, meaning, and selfhood. In this paper, I set out what I call a ‘co-constitutive’ view about the relation between time and subjectivity, which can be attributed to some phenomenologists (i.e. Merleau-Ponty and Heidegger). I also emphasise the extension of this co-constitutive view in habits, including in some of the distinctive temporal habits associated with psychopathological instances of addiction and obsessive-compulsive disorder (OCD). On that basis, I ask some critical questions about views of epistemic rationality and temporal biases that are influential in decision theory and in some accounts of well-being and psychopathology. Rather than view time biases as an irrational evolutionary outcome, I contend that what is needed is a deeper understanding of the relationship between lived-time, habits, and motivation. The question of the rationality of time-preferences needs to be understood in that more situated context that involves a ‘temporal faith’, rather than a view from nowhen, if it is to have action-guiding and normative force.

Enactivism has recently faced criticism for either leaning too heavily on philosophical speculation without clear scientific grounding, or relying on quite old empirical work in cognitive science, especially concerning sensorimotor actions. While one can push back against such charges, in this paper we take a different approach. We will use metabolic and microbiome research as a case study to help make this problem vivid, and to outline a path forward. First, we contend that a closer look at metabolism and microbiota-host interactions places pressure upon some of the core ‘autopoietic’ concepts of enactivism, including self-production, autonomy, and operational closure. This research instead appears to emphasise heteronomy and symbiosis in cognitive, developmental, and evolutionary processes, posing in effect an ontological challenge. Second, it also raises some questions about enactivism’s traditional avoidance of reductionist explanations, suggesting that there is an epistemic need for a philosophy of science that clarifies how to integrate more reductive biological programs within holistic enactivist frameworks. To meet these challenges, we argue that enactivism needs to moderate its commitments to autopoietic theory.

Throughout much of the twentieth century, the relationship between analytic and continental philosophy has been one of disinterest, caution or hostility. Recent debates in philosophy have highlighted some of the similarities between the two approaches and even envisaged a post-continental and post-analytic philosophy. Opening with a history of key encounters between philosophers of opposing camps since the late nineteenth century - from Frege and Husserl to Derrida and Searle - the book goes on to explore in detail the main methodological differences between the two approaches. This covers a very wide range of topics, from issues of style and clarity of exposition to formal methods arising from logic and probability theory. The final section of this book presents a balanced critique of the two schools' approaches to key issues such as time, truth, subjectivity, mind and body, language and meaning, and ethics. "Analytic versus Continental" is the first sustained analysis of both approaches to philosophy, examining the limits and possibilities of each. It provides a clear overview of a much-disputed history and, in highlighting the strengths and weaknesses of both traditions, also offers future directions for both continental and analytic philosophy.

Current evidence suggests that the efficacy of psychedelic therapy depends, in part, on the character of psychedelic experiences themselves. One pronounced aspect of psychedelic experiences is alterations to the experience of time, including reports of timelessness or transcending time. However, how we should interpret such reports remains unclear, and this lack of clarity has philosophical and clinical implications. For instance, “true” timelessness may be considered antithetical to having any experience at all, and descriptions of experiences involving “timelessness” are known to be diverse and of varying clinical significance. In this article, we utilize a phenomenological approach to the study of temporality to highlight ambiguities in current constructs used to assess psychedelic experiences. In doing so, we advance some preliminary phenomenological accounts of psychedelic therapy’s mechanisms of action, such as psychedelic temporality acting as a kind of counterpoint for depressive temporality. We conclude by outlining how a dedicated phenomenological research program can provide a nuanced map of psychedelic temporality, guiding future research in a manner that addresses both philosophical and clinical ambiguities.

Psychedelic-assisted therapy (PAT) is an emerging intervention in psychiatry, for which there is preliminary evidence for effectiveness in eating disorders (EDs). The subjective psychedelic experience is considered an important driver of positive outcomes following PAT; however, conventional study design approaches often overlook many of the nuances inherent to the experience. Consequently, considerable information is lost between the first-person account and its scientific interpretation and documentation. Phenomenology—a philosophical and empirical approach to studying lived experience—offers tools to assess and understand the experiential mechanisms of PAT. This commentary advances the case for a phenomenological approach to PAT research in EDs, focusing on key domains of experience that underlie both ED psychopathology and psychedelic experiences, including embodiment, intersubjectivity, affectivity, temporality, spatiality and selfhood. We define and outline these phenomenological domains of EDs and psychedelic experiences and critically examine current measurement approaches. Following, we provide specific research recommendations, including phenomenologically grounded qualitative research and microphenomenology (i.e., the assessment of short-lived, pre-conscious experiences), to more fully capture psychedelic experiences and determine their significance for ED outcomes. The application of phenomenology to the PAT study design may contribute to a better understanding of how individuals experience PAT and generate testable hypotheses to advance psychedelic interventions.

Having initially not had the attention of Sartre or Heidegger, Merleau-Ponty's work is arguably now more widely influential than either of his two contemporaries. "Merleau-Ponty: Key Concepts" presents an accessible guide to the core ideas which structure Merleau-Ponty's thinking as well as to his influences and the value of his ideas to a wide range of disciplines. The first section of the book presents the context of Merleau-Ponty's thinking, the major debates of his time, particularly existentialism, phenomenology, the history of philosophy and the philosophy of history and society. The second section outlines his major contributions and conceptual innovations. The final section focuses upon how his work has been taken up in other fields besides philosophy, notably in sociology, cognitive science, health studies, feminism and race theory.

In this chapter, I revisit the question of the philosophical significance of the Great War upon the trajectory of philosophy in the twentieth century. While accounts of this are very rare in philosophy, and this is itself symptomatic, those that are given are also strangely implausible. They usually assert one of two things: that the War had little or no philosophical significance because most of the major developments had already begun, or—at the opposite extreme—they maintain that nothing was ever the same in philosophy (as elsewhere). On the latter view, the creation of the so-called analytic-continental ‘divide’ is but one notable philosophical consequence of the Great War. I want here to steer a middle-way between these positions, both having a grain of truth but over-playing their respective hands.

Concerns around Generative Artificial Intelligence (GenAI) in higher education have so far largely centred on assessment integrity, resulting in fundamental questions about students’ broader engagement with these tools remaining underexplored. This paper reports on the findings of a survey that forms part of a wider study, comprising the first empirical investigation of GenAI use by university students as a method of engaging with their academic readings. Our survey of 101 students shows that over half of all students surveyed used GenAI to some degree as a method of engaging with their unit readings. Our findings suggest that students turn to these tools in response to time constraints and conceptual difficulties, while maintaining complex attitudes toward their use: most welcome their availability, yet few report trusting or relying on GenAI-generated interpretations or summaries of texts. Importantly, our data reveals substantial demographic variations in usage patterns, with international students and those taking subjects as electives showing significantly higher rates of AI use to assist with reading. This suggests GenAI tools may be serving as important mediators for attempting to overcome epistemic barriers to learning, particularly for students who face additional linguistic or disciplinary challenges.

In this paper I return to Hubert Dreyfus’ old but influential critique of artificial intelligence, redirecting it towards contemporary predictive processing models of the mind (PP). I focus on Dreyfus’ arguments about the “frame problem” for artificial cognitive systems, and his contrasting account of embodied human skills and expertise. The frame problem presents as a prima facie problem for practical work in AI and robotics, but also for computational views of the mind in general, including for PP. Indeed, some of the issues it presents seem more acute for PP, insofar as it seeks to unify all cognition and intelligence, and aims to do so without admitting any cognitive processes or mechanisms outside of the scope of the theory. I contend, however, that there is an unresolved problem for PP concerning whether it can both explain all cognition and intelligent behavior as minimizing prediction error with just the core formal elements of the PP toolbox, and also adequately comprehend (or explain away) some of the apparent cognitive differences between biological and prediction-based artificial intelligence, notably in regard to establishing relevance and flexible context-switching, precisely the features of interest to Dreyfus’ work on embodied indexicality, habits/skills, and abductive inference. I address several influential philosophical versions of PP, including the work of Jakob Hohwy and Andy Clark, as well as more enactive-oriented interpretations of active inference coming from a broadly Fristonian perspective.

In this paper, I consider a challenge that naturalism poses for embodied cognition and enactivism, as well as for work on phenomenology of the body that has an argumentative or explanatory dimension. It concerns the connection between embodiment and emergence. In the commitment to explanatory holism, and the irreducibility of embodiment to any mechanistic and/or neurocentric construal of the interactions of the component parts, I argue there is (often, if not always) an unavowed dependence on an epistemic and metaphysical role for emergence, especially concerning certain embodied capacities (motor-intentionality, know-how, skilful habits, affordances, etc.). While the problem of emergence is standardly dismissed as a problem for phenomenology, which brackets away the kind of materialist (and scientific) picture from which reflection on emergence derives, I argue that once a phenomenologist takes a fully-fledged embodied turn, they also have a genuine dilemma of emergence to confront, and I evaluate the relevant options.

The use of philosophical phenomenology for conceptual debates in psychiatric nosology and psychopathology is beginning to be recognized. In this paper, we extend this trajectory to include Tourette Syndrome, focusing on so-called premonitory urges (PU) preceding Tourettic tics. We clarify some inconsistencies around typology in both phenomenological description and medical classification (i.e., in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, Text Revision, International Classification of Diseases, 10th edition [World Health Organization, 2004], and the scales that elicit PU). We show how a less typological approach might be usefully deployed in the field, that being the dimensional approach developed by Fernandez (2019a; 2019b). We test both the typological and dimensional approaches in relation to the experience and etiological role of PU in Tourette’s syndrome. Based on our synthesis of existing studies and new information garnered through phenomenological interviews (using an approach associated with “micro-phenomenology”), we argue that the role of PU in nosology challenges both the current “operational” criteria favored by the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, Text Revision, that are focused on behaviorally observed symptoms, as well as essential and prototypical phenomenological descriptions about a given “type” of experience.

This fully revised and updated 2nd edition provides a comprehensive reference guide to existentialism, featuring key chapters on key existentialist thinkers, as well as chapters applying existentialism to subject areas ranging across politics, literature, feminism, religion, the emotions, cognitive science, and poststructuralism. Contemporary developments in the field of existentialism that speak to issues of identity and exclusion are explored in 4 new chapters on race, gender, disability, and technology, whilst the 5th new chapter new chapter outlines analytic philosophy's complicated relationship to existentialism. Presenting the field of existentialism beyond the European tradition, this edition also includes a new key thinker chapter on Frantz Fanon, alongside Kierkegaard, Nietzsche, Heidegger, Sartre and de Beauvoir, as well as new engagement with the work of scholars on race and existentialism, including Lewis R. Gordon, George Yancy, and Richard Wright. The resources section at the end of the book includes an updated A to Z glossary, and timeline of key events, texts and thinkers in existentialism, as well as a list of relevant organisations, and an annotated guide to further reading, making this 2nd edition an invaluable text for scholars and students alike.

Most readers of Sartre focus only on the works written at the peak of his influence as a public intellectual in the 1940s, notably "Being and Nothingness". "Jean-Paul Sartre: Key Concepts" aims to reassess Sartre and to introduce readers to the full breadth of his philosophy. Bringing together leading international scholars, the book examines concepts from across Sartre's career, from his initial views on the "inner life" of conscious experience, to his later conceptions of hope as the binding agent for a common humanity. The book will be invaluable to readers looking for a comprehensive assessment of Sartre's thinking - from his early influences to the development of his key concepts, to his legacy.

In this paper, we consider the implications of Grace de Laguna and Joel Katzav's work for the charge of conservatism against the analytic tradition. We differentiate that conservatism into three kinds: starting place; path dependency; and modesty. We also think again about gender in philosophy, consider the positive account of speculative philosophy presented by de Laguna and Katzav in comparison to some other naturalist trajectories, and conclude with a brief Australian addendum that reflects on a similar period in our own country which was also associated with the professional institutionalisation of analytic philosophy.

Despite rarely explicitly thematizing the problem of dirty hands, this essay argues that Merleau-Ponty’s political work can nonetheless make some important contributions to the issue, both descriptively and normatively. Although his political writings have been neglected in recent times, his interpretations of Marxism and Machiavelli enabled him to develop an account of political phronesis and virtù that sought to retain the strengths of their respective positions without succumbing to their problems. In the process, he provides grounds for generalizing the problem of “dirty hands” beyond Michael Walzer’s influential understanding that pertains primarily to “emergencies” and singular time-slice actions, and addresses concerns about the coherence of the very idea that there is justified action that one ought to do which remains wrong. Merleau-Ponty does this by emphasizing the diachronic relationship between theoretical principles and concrete political action over a period of time, thus imbuing the problem of dirty hands with a historicity that is not sufficiently recognized in the more static and action-focused discussions.

In the debates on phenomenal consciousness that occurred over the last 20 years, Sartre’s analysis of pre-reflective consciousness has often been quoted in defence of a distinction between first- and third-personal modes of givenness that naturalists reject. This distinction aims both at determining the specificity of the access one has to their own thoughts, beliefs, intentions, or desires, and at justifying the particular privilege that one enjoys while making epistemic claims about their own mental states. This chapter defends an interpretation of Sartre’s theory of pre-reflective consciousness that does not put him completely at odds with the naturalist critique and stresses that one’s pre-reflective experience should not be understood in terms of first-/third-person differentiation. This pre-reflective dimension of experience nevertheless allows a peculiar access to oneself, which grants no infallible epistemic privilege to the first-person, but lays the ground for a transformative process that makes self-knowledge possible.

Although their work in the philosophy of biology is not well known, Heidegger, Merleau-Ponty, and Ruyer all offer interesting and heterodox accounts of the life and environmental sciences and the organism in particular. In this chapter, we discuss their respective views, with a focus on their shared criticisms of Neo- Darwinism and the way this tradition grasped the structural coupling between organism and environment. We also outline some significant differences between each of them concerning how to conceive of that holistic relation and the extent of “captivation” of the animal to its environment. Given that there are indications that the twenty-first century might be post-genomic/epigenetic, we argue that it is worth revisiting these neglected organicist trajectories that sought to navigate between mechanism and vitalism.

Phenomenology has been described as a “non-argumentocentric” way of doing philosophy, reflecting that the philosophical focus is on generating adequate descriptions of experience. But it should not be described as an argument-free zone, regardless of whether this is intended as a descriptive claim about the work of the “usual suspects” or a normative claim about how phenomenology ought to be properly practiced. If phenomenology is always at least partly in the business of arguments, then it is worth giving further attention to the role and form of phenomenological argumentation, how it interacts with its more strictly descriptive component, and the status of phenomenological claims regarding conditions for various kinds of experience. I contend that different versions of phenomenological reasoning encroach upon argument forms that are commonly thought to be antithetical to phenomenology, notably abductive reasoning, understood in terms of its role in both hypothesis generation and in terms of justification. This paper identifies two main steps to making this case. The first step takes seriously the consequences of the intrinsically dialectical aspect of phenomenology in intersection with other modes of philosophy, the natural attitude, and non-philosophy. The second step focuses on transcendental reflection and arguments about the conditions/structures they contain. Together, these two steps aim to rescue phenomenology from the objection that it has an “ostrich epistemology” with regard to the ostensible purity of description, the intuition of essences, or the “conditions” ascertained through transcendental reflection.

Although pragmatism and phenomenology have both contributed significantly to the genealogy of so-called “4E” – embodied, embedded, enactive and extended – cognition, there is benefit to be had from a systematic comparative study of these roots. As existing 4E cognition literature has tended to emphasise one or the other tradition, issues remain to be addressed concerning their commonalities – and possible incompatibilities. We begin by exploring pragmatism and phenomenology’s shared focus on contesting intellectualism, and its key assumption of mindedness as representation. We then outline distinctive insights from both traditions regarding the nature and role of habits, in order to put forward a habit-based epistemology as an alternative to the Cartesian idea-based epistemology that has dominated modern philosophy. We pay particular attention to the work of classical pragmatist C.S. Peirce, arguing that his semiotics, which analyses sign-use as habit, shows how theorists of embodied cognition can break a certain false dichotomy between embodiment and logical or intellectual structure which has prevented them from fully theorising propositional knowledge. In this way, our work both augments and challenges the Dewey/Merleau-Ponty connection that has been much more extensively explored by the field.

The modern era has witnessed an extraordinary and unprecedented growth in our empirical knowledge regarding the human body. This raises the question: what, if anything, can phenomenology teach us about the body that the empirical sciences cannot? Whereas common sense and empirical sciences begin from the body as straightforwardly and obviously given and go on from there to think about what this thing is, what it is made up of, and how it originated, phenomenology steps back from the straightforward fact in order to ask: what is the structure of the body as an appearance? This chapter considers how some of the main figures in phenomenology have tried to answer this question. The body is not explicitly discussed in what might be thought of as the two foundational works of phenomenology: Husserl’s Logical Investigations and Heidegger’s Being and Time. Nevertheless, these works set the stage for the subsequent phenomenology of the body by describing the phenomena of multidimensionality and horizontality. Our first task will be to sketch out how these phenomena were described in the foundational works. This sets up our exposition of the body as a multidimensional phenomenon. We consider Husserl’s treatment of the body in Ideas II. We also examine how the Husserlian insights were taken up and developed by Jean-Paul Sartre and Maurice Merleau-Ponty. In conclusion we raise some critical questions regarding a phenomenological focus on the body and its multidimensionality.

As neither a classical naturalist nor a non-naturalist, Merleau-Ponty appears to be a moderate or liberal naturalist. But can a phenomenologist really be a naturalist, even a liberal one? A lot hinges on how we tease this out, both as to whether it is plausible to claim Merleau-Ponty as a liberal naturalist (I argue it is), and as to whether it is an attractive and coherent position. Indeed, despite its important challenges to orthodox naturalism, there are arguably two traps to avoid. If it becomes too liberal, we get: dualism or an ontological pluralism that is difficult to distinguish from a constructivism; or, in seeking to sidestep that metaphysical dilemma, there is sometimes an insistence on an overly neat methodological separation between description/understanding and explanation that is belied in practice (both scientific and philosophical). It is doubtful that such positions can legitimately claim to be naturalist in orientation, liberal or not. Merleau-Ponty’s philosophy avoids these traps, however, and it is thus a useful resource for contemporary work trying to navigate between scientific naturalism and non-naturalism

The role of the body in cognition is acknowledged across a variety of disciplines, even if the precise nature and scope of that contribution remain contentious. As a result, most philosophers working on embodiment—e.g. those in embodied cognition, enactivism, and ‘4e’ cognition—interact with the life sciences as part of their interdisciplinary agenda. Despite this, a detailed engagement with emerging findings in epigenetics and post-genomic biology has been missing from proponents of this embodied turn. Surveying this research provides an opportunity to rethink the relationship between embodiment and genetics, and we argue that the balance of current epigenetic research favours the extension of an enactivist approach to mind and life, rather than the extended functionalist view of embodied cognition associated with Andy Clark and Mike Wheeler, which is more substrate neutral.
