Suppose you want to do as much good as possible. What should you do? According to members of the effective altruism movement—which has produced much of the thinking on this issue and counts several moral philosophers as its key protagonists—we should prioritise among the world’s problems by assessing their scale, solvability, and neglectedness. Once we’ve done this, the three top priorities, not necessarily in this order, are (1) aiding the world’s poorest people by providing life-saving medical treatments or alleviating poverty (...) itself, (2) preventing global catastrophic risks, such as those posed by nuclear war or rogue artificial intelligence, and (3) ending factory farming. These claims are both plausible and striking. If correct, they should prompt a stark revision of how we approach our altruistic activities. However, the project of determining how to do the most good—as opposed to say, whether we should do the most good—has only recently, within the last ten years, become the subject of serious academic attention. Many key claims have not yet been carefully scrutinised. This is a cause for concern: are effective altruists doing good badly? In this thesis, I critique and develop some of the latest claims about how individuals can do the most good. I do this in three areas: the value of saving lives (preventing premature deaths), how best to improve lives (making people happier during their lives), and cause prioritisation methodology (frameworks for determining which problems are the highest priorities). In each case, I raise novel theoretical considerations that, when incorporated, change the analysis. Roughly speaking, my main conclusions are (1) saving lives is not as straightforwardly good we tend to suppose, may not be good at all, and is not clearly a priority; (2) happiness can be measured through self-reports and, based on the self-reported evidence, treating mental health stands out as an overlooked problem that may be an even more cost-effective way to improve lives than alleviating poverty; (3) the cause prioritisation methodology proposed by effective altruists needs to be moderately reconceptualised and, when it is, it turns out it is not as illuminating a tool as we might have thought and hoped.

Numerous and diverse reports indicate the efficacy of shamanic plant adjuncts (e.g., iboga, ayahuasca, psilocybin) for the care and treatment of addiction, post-traumatic stress disorder, cancer, cluster headaches, and depression. This article reports on a first-person healing of lifelong asthma and atopic dermatitis in the shamanic context of the contemporary Peruvian Amazon and the sometimes digital ontology of online communities. The article suggests that emerging language, concepts, and data drawn from the sciences of plant signaling and behavior regarding (...) “plant intelligence” provide a useful heuristic framework for comprehending and actualizing the healing potentials of visionary plant “entheogens” (Wasson 1971) as represented both through first-person experience and online reports. Together with the paradigms and practices of plant signaling, biosemiotics provides a robust and coherent map for contextualizing the often reported experience of plant communication with ayahuasca and other entheogenic plants. The archetype of the “plant teachers” (called Doctores in the upper Amazon) is explored as a means for organizing and interacting with this data within an epistemology of the “hallucination/perception continuum (Fischer 1975). “Ecodelic” is offered as a new linguistic interface alongside “entheogen” (Wasson 1971).

Plant biologists widely accept plants demonstrate capacities for intelligence. However, they disagree over the interpretive, ethical and nomenclatural questions arising from these findings: how to frame the issue and how to signify the implications. Through the trope of 'plant neurobiology' describing plant root systems as analogous to animal brains and nervous systems, plant intelligence is mobilised to raise the status of plants. In doing so, however, plant neurobiology accepts an anthropocentric moral extensionist framework (...) requiring plants to anthropomorphically meet animal standards to be deserving of moral respect. I argue this strategy is misguided because moral extensionism is an erroneous ontological foundation for ethics. (shrink)

In the Timaeus, plants are granted soul, and specifically the sort of soul capable of perception and desire. Also in the Timaeus, perception requires the involvement of to phronimon.

I argue that we can neither avoid granting plants sensation in just this sense, nor can we suppose that `to phronimon' is something devoid of intelligence. Indeed, plants must be related to intelligence, if they are to be both orderly and (...) good. Plants must have individual souls if they are to be distinguished from each other, each with an orderly life; but the intelligence their perceptions require is not similarly individuated, for their ultimate good is only derivative: it is only as completing the body of the cosmos that plants are good things. Plants have their own perceptions and desires in virtue of the intelligence ordering the cosmos as a whole. (shrink)

‘Plant neurobiology’ has emerged in recent years as a multidisciplinary endeavor carried out mainly by steady collaboration within the plant sciences.

Resources (...) from philosophy and cognitive science are central to such an interdisciplinary project, if plant neurobiology is to maintain its target well-focused.

According to F. Adams [this journal, vol. 68, 2018] cognition cannot be realized in plants or bacteria. In his view, plants and bacteria respond to the here-and-now in a hardwired, inflexible manner, and are therefore incapable of cognitive activity. This article takes issue with the pursuit of plant cognition from the perspective of an empirically informed philosophy of plant neurobiology. As we argue, empirical evidence shows, contra Adams, that plant behavior is in many ways analogous to animal (...) behavior. This renders plants suitable to be described as cognitive agents in a non-metaphorical way. Sections two to four review the arguments offered by Adams in light of scientific evidence on plant adaptive behavior, decision-making, anticipation, as well as learning and memory. Section five introduces the ‘phyto-nervous’ system of plants. To conclude, section six resituates the quest for plant cognition into a broader approach in cognitive science, as represented by enactive and ecological schools of thought. Overall, we aim to motivate the idea that plants may be considered genuine cognitive agents. Our hope is to help propel public awareness and discussion of plant intelligence once appropriately stripped of anthropocentric preconceptions of the sort that Adams' position appears to exemplify.

A large part of technological advances, especially in the field of industry, have been focused on the optimization of productive processes. However, the detection of anomalies has turned out to be a great challenge in fields like industry, medicine or stock markets. The present work addresses anomaly detection on a control level plant. We propose the application of different intelligent techniques, which allow to obtain one-class classifiers using real data taken from the correct plant operation. The performance of (...) each classifier is assessed and validated with real created faults, achieving successful overall results. (shrink)

Philosophers have traditionally held that propositions mark the domain of rational thought and inference. Many philosophers have held that only conceptually sophisticated creatures like us could have propositional attitudes. But in recent decades, philosophers have adopted increasingly liberal views of propositional attitudes that encompass the mental states of various non-human animals. These views now sit alongside more traditional views within the philosophical mainstream. In this paper I argue that liberalized views of propositional attitudes are so liberal that they encompass states (...) of all sorts of apparently mindless systems like circadian clocks in plants. I begin by arguing that on the most well-developed and widely endorsed theories of underived representation in philosophy, circadian clocks qualify as representations. I then argue that standard reasons for thinking that perceptual states and pictures have propositional content carry over to circadian clocks. Finally, I argue that circadian representations in plants play the kind of functional role that is widely taken to be partly constitutive of belief-like attitudes. So according to mainstream theories of representation, propositions, and attitudes, plants have propositional attitudes. Yet on other more traditional views, this conclusion would seem absurd. So, contrary to appearances, there is no shared, stable understanding of what propositional attitudes are in contemporary philosophy. (shrink)

It has recently been asserted that legislative moves to consider plants as ethical subjects are philosophically foolish because plants lack autonomy. While by no means the sole basis or driving criterion for moral behavior, it is possible to directly challenge skeptical attitudes by constructing a human-plant ethics centered on fundamental notions of autonomy. Autonomous beings are agents who rule themselves, principally for their own purposes. A considerable body of evidence in the plant sciences is increasingly recognizing the capacity (...) of plants to assess, perceive, and act on their environment. The primary purpose of their doing so is to generate the conditions for their own flourishing. With these plant purposes in mind, it is evidentially inappropriate to treat plants purely as instruments. In this age of environmental crisis, knowledge of plant intelligence and autonomy opens up a new debate on respecting and promoting the well-being of the plants that make life on Earth possible.

To what extent can plants be considered cognitive from the perspective of embodied cognition? Cognition is interpreted very broadly within embodied cognition, and the current evidence for plant intelligence might find an important theoretical background here. However, embodied cognition does stress the presence of animal-like perception-action coupling as a key feature for cognitive systems to arise. In this paper, we discuss whether, or to what extent, plants may qualify as cognitive systems, given this criterion.

Compte rendu de Quentin Hiernaux, Du comportement végétal à l’intelligence des plantes?

What can we learn from plants? Which forms of intelligence and knowledge can we discover by dedicating ourselves to understanding the life of a plant, its characteristics, interactions with the environment and cultural narratives? This article aims to bridge recent studies in plant intelligence, Semiotics and creative processes. Departing form the idea that the world arrived at a critical situation and the planet Earth cannot continue being exploited as an infinite source, we argue that it is (...) necessary to promote transformations in our culture, abandoning the anthropocentric framework and looking for new perspectives. In this sense, connecting communication, art, science and education, the purpose of Plant Portraits is to create experiences and propitiate encounters that catalyse the awakening of an expanded and integrated consciousness.

Organisms change their shape and behavior during ontogenesis in response to incentives—what biologists call “phenotypic plasticity” or what is called here more specifically “behavioral plasticity.” Such plasticity is usually in the direction of enhancing welfare or fitness. In light of basic concepts in economics, such behavioral plasticity is nothing but rationality. Such rationality is not limited to organisms with neural systems. It also characterizes brainless organisms such as plants, fungi, and unicellular organisms. The gist of the article is the distinction (...) between rationality and intelligence. Whereas rationality is ubiquitous in all organisms, intelligence varies in degrees depending on division of labor that may involve the evolution of a neural system. This article aims to defend the universality of rationality—the Organismus oeconomicus hypothesis. It argues that neither the notion of bounded rationality of behavioral economics nor Herbert Simon’s “procedural rationality” can ultimately undermine the Organismus oeconomicus hypothesis. (shrink)

Plant and animal species are information-processing entities of such complexity, integration, and adaptive competence that it may be scientifically fruitful to consider them intelligent. The possibility arises from the analogy between learning and evolution, and from recent developments in evolutionary science, psychology and cognitive science. Species are now described as spatiotemporally localized individuals in an expanded hierarchy of biological entities. Intentional and cognitive abilities are now ascribed to animal, human, and artificial intelligence systems that process information adaptively, and (...) that manifest problem-solving abilities. The structural and functional similarities between such systems and species are extensive, although they “are usually obscured by population-genetic metaphors that have nonetheless contributed much to our understanding of evolution.In this target article, I use Sewall Wright's notion of the “adaptive landscape” to compare the performances of evolving species to those of intelligent organisms. With regard to their adaptive achievements and the kinds of processes by which they are achieved, biological species compare very favorably to intelligent animals by virtue of interactions between populations and their environments, between ontogeny and phylogeny, and between natural, interdemic, organic, and species selection. Addressing the question of whether species are intelligent could help to refine our ideas about species, evolution, and intelligence, and could open new lines of empirical and theoretical inquiry in many disciplines.

Some biologists now argue in favour of a pluralistic approach to plant activities, understandable both from the classical perspective of physiological mechanisms and that of the biology of behaviour involving choices and decisions in relation to the environment. However, some do not hesitate to go further, such as plant “neurobiologists” or philosophers who today defend an intelligence, a mind or even a plant consciousness in a renewed perspective of these terms. To what extent can we then (...) adhere to pluralism in the study of plant behaviour? How does this pluralism in the study and explanation of plant behaviour fit into, or even build itself up, in a broader history of science? Is it a revolutionary way of rethinking plant behaviour in the twenty-first century or is it an epistemological extension of an older attitude? By proposing a synthesis of the question of plant behaviour by selected elements of the history of botany, the objective is to show that the current plant biology is not unified on the question of behaviour, but that its different tendencies are in fact part of a long botanical tradition with contrasting postures. Two axes that are in fact historically linked will serve as a common thread. 1. Are there several ways of understanding or conceiving plant behaviour within plant sciences and their epistemology? 2. Can the behaviour of a plant be considered in the same way as that of an animal? The working hypothesis defended in this article consists in showing that the current opposition between growth, development and reductionist physiology on the one hand and the biology of behaviour involving sensitivity and choices in plant activity on the other hand has been built up through the history of botany.

Due to the COVID-19 pandemic, educational centers and universities in Venezuela have closed their physical plants and are migrating to emergency remote education to continue with academic programs. This empirical study aimed to analyze the predictive capacity of academic self-efficacy and emotional intelligence skills on each of the dimensions of psychological well-being. We employed a cross-sectional predictive design. The sample comprised 277 university students, of which 252 were female. Their ages ranged from 18 to 45 years, with a mean (...) of 20.35. Non-probabilistic chance sampling was used. For data collection, we used an anonymous online form, contacted students by mail, and invited them to participate in the study. Questionnaires were available between 217 and 227 days of decreed quarantine in Venezuela. The results indicated average levels of academic self-efficacy, emotional intelligence: clarity, attention y repair, and psychological well-being. We found differences according to sex and age, specifically in emotional regulation and in bonds of psychological well-being favoring men, respectively. Regarding age, statistically significant differences were found in the group of students older than 21 years with higher perception of psychological well-being and in each of its dimensions. Emotional intelligence and academic self-efficacy were found to be significant predictors of psychological well-being and its dimensions, specifically on control, links, projects, acceptance, and total well-being. It was concluded that emotional intelligence and academic self-efficacy are protective psychological resources of psychological well-being that should be promoted at university to mitigate the negative effects of the pandemic on the mental health of young people.

This article analyses Averroes/Ibn Rushd´s (d. 1198) views on motherhood in his commentary on Plato´s Republic. The starting point for this inquiry is Averroes´ comparison of the women in his society to plants. Averroes argues that performing the duties of motherhood, i.e. being children´s primary caregiver, does not constitute nor involve any form of human virtue. Averroes´ low esteem for activities of motherhood has hitherto been ignored. This paper argues that the comparison of women to plants does not hinge on (...) societal criticism solely but on at least two additional factors: Aristotle on plants in De Anima and on this low appreciation for tasks of parenthood. Furthermore, this paper aims to show that the latter is incompatible with Aristotle´s views in his ethics and biology, which emphasize, respectively, the friendship that characterizes the parent-child relationship and the intelligence and virtue needed to raise the next generation.

It remains at best controversial to claim, non-figuratively, that plants are cognitive agents. At the same time, it is taken as trivially true that many animals are cognitive agents, arguably through an implicit or explicit appeal to natural science. Yet, any given definition of cognition implicates at least some further processes, such as perception, action, memory, and learning, which must be observed either behaviorally, psychologically, neuronally, or otherwise physiologically. Crucially, however, for such observations to be intelligible, they must be counted (...) as evidence for some model. These models in turn point to homologies of physiology and behavior that facilitate the attribution of cognition to some non-human animals. But, if one is dealing with a model of animal cognition, it is tautological that only animals can provide evidence, and absurd to claim that plants can. The more substantive claim that, given a general model of cognition, only animals but not plants can provide evidence, must be evaluated on its merits. As evidence mounts that plants meet established criteria of cognition, from physiology to behavior, they continue to be denied entry into the cognitive club. We trace this exclusionary tendency back to Aristotle, and attempt to counter it by drawing on the philosophy of modelling and a range of findings from plant science. Our argument illustrates how a difference in degree between plant and animals is typically mistaken for a difference in kind. (shrink)

Plants have been—and, for reasons of human sustenance and creative inspiration, will continue to be—centrally important to societies globally. Yet, plants—including herbs, shrubs, and trees—are commonly characterized in Western thought as passive, sessile, and silent automatons lacking a brain, as accessories or backdrops to human affairs. Paradoxically, the qualities considered absent in plants are those employed by biologists to argue for intelligence in animals. Yet an emerging body of research in the sciences and humanities challenges animal-centred biases in determining (...) consciousness, intelligence, volition, and complex communication capacities amongst living beings. In light of recent theoretical developments in our understandings of plants, this article proposes an interdisciplinary framework for researching flora: human-plant studies. Building upon the conceptual formations of the humanities, social sciences, and plant sciences as advanced by Val Plumwood, Deborah Bird Rose, Libby Robin, and most importantly Matthew Hall and Anthony Trewavas, as well as precedents in the emerging areas of human-animal studies, I will sketch the conceptual basis for the further consideration and exploration of this interdisciplinary framework.

In his extensive and revolutionary work, the biologist and philosopher Jakob von Uexküll examined the animal kingdom, laying the first foundations for a wider reflection on non-human animal agency in ecosystems. However, the scientist did not include in his reflection on Umwelt plants and fungi, widely considered passive organisms in the 1900s. In this paper, we will try to find the contact points between the biologist’s theories and contemporary botanical discoveries, taking into account some of the findings on plant (...) agency, communication, and interaction even with fungi, crucial actors in the vegetal organization of the territory. The core of the work will be to demonstrate that plants could fit in an integrated and extended theory of Umwelt abandoning the “zoocentric” perspective that permeated the studies on botanical species. To achieve this aim, it will be necessary to first deconstruct the historical theorization of plants’ passivity, which has ancient roots and was enforced in some philosophical perspectives of the 20th century. Consequentially, with two focuses, the first one on communication and the second one on agency, the paper will highlight the possibilities and horizons that could be opened through a comparison between the theories of von Uexküll and nowadays botanical breakthroughs.

Heidegger claims that it is the ultimate job of philosophy to preserve the force of the “elemental words” in which human beings express themselves. Many of these elemental words are found in the various cosmogonies that have informed cultural ideologies around the world. Two of these “elemental words,” which shape the ideologies are the animal-model of the cosmos in Plato’s Timaeus and the mechanical models developed in the 17th-18th centuries in Europe. The paper argues that Daoism employs a third, and (...) neglected, plant-model of cosmogony and of human life that provides an illuminating contrast to the other more well-known models. First, Plato’s animal-model of the cosmos and, second, the alternative Daoist plant-model of the cosmos are discussed. Third, the paper replies to the objection that the organic model in general and the plant-model in particular cannot accommodate human freedom. Fourth, it is shown how the Daoist plant-model supports a novel account of the central Daoist notion of wu-wei. Fifth, the paper rebuts the objection that the Daoist plant-model of the cosmos and human life is fatally nihilistic. Sixth, the paper argues that the Daoist account of the origin of human religion, art and historical feeling cannot be properly understood apart from its plant-model of the cosmos and human life.

With renewable energy being increasingly connected to power grids, pumped storage plants play a very important role in restraining the fluctuation of power grids. However, conventional control strategy could not adapt well to the different control tasks. This paper proposes an intelligent nonlinear model predictive control strategy, in which hydraulic-mechanical and electrical subsystems are combined in a synchronous control framework. A newly proposed online sequential extreme learning machine algorithm with forgetting factor is introduced to learn the dynamic behaviors of the (...) coupling system. Specifically, the initial learning parameters are optimized by prior-knowledge learning and a new self-adaptive adjustment strategy is also put forward. Subsequently, the stair-like control strategy and artificial sheep algorithm are used in rolling the optimization mechanism to replace the existing complex differential geometric solutions. Comparative experiments are carried out under different working conditions based on a PSP in China. The results show that the influence from coupling factors can be considerable and the proposed MPC strategy indicates superiority in voltage and load adjustment as well as the frequency oscillation suppression.

Although Darwin insisted that human intelligence could be fully explained by the theory of evolution, the codiscoverer of natural selection, Alfred Russel Wallace, claimed that abstract intelligence was of no use to ancestral humans and could only be explained by intelligent design. Wallace’s apparent paradox can be dissolved with two hypotheses about human cognition. One is that intelligence is an adaptation to a knowledge-using, socially interdependent lifestyle, the “cognitive niche.” This embraces the ability to overcome the evolutionary (...) fixed defenses of plants and animals by applications of reasoning, including weapons, traps, coordinated driving of game, and detoxification of plants. Such reasoning exploits intuitive theories about different aspects of the world, such as objects, forces, paths, places, states, substances, and other people’s beliefs and desires. The theory explains many zoologically unusual traits in Homo sapiens, including our complex toolkit, wide range of habitats and diets, extended childhoods and long lives, hypersociality, complex mating, division into cultures, and language (which multiplies the benefit of knowledge because know-how is useful not only for its practical benefits but as a trade good with others, enhancing the evolution..

This paper presents the intelligent virtual animals that inhabit Omosa, a virtual learning environment to help secondary school students learn how to conduct scientific inquiry and gain concepts from biology. Omosa supports multiple agents, including animals, plants, and human hunters, which live in groups of varying sizes and in a predator-prey relationship with other agent types (species). In this paper we present our generic agent architecture and the algorithms that drive all animals. We concentrate on two of our animals to (...) present how different parameter values affect their movements and inter/intra-group interactions. Two evaluations studies are included: one to demonstrate the effect of different components of our architecture; another to provide domain expert validation of the animal behavior. (shrink)

I propose a framework, derived from moral theory, for assessing the moral status of intelligent machines.

I propose that the threshold for any moral obligation should be the "functional morality" of Wallach and Allen [20], (...) while the upper limit of our obligations should not exceed the upper limit of our obligations toward plants, trees, and other environmental entities.

In "Culture and Value" Wittgenstein remarks that the truly "religious man" thinks himself to be, not merely "imperfect" or "ill," but wholly "wretched." While such sentiments are of obvious biographical interest, in this paper I show why they are also worthy of serious philosophical attention. Although the influence of Wittgenstein's thinking on the philosophy of religion is often judged negatively (as, for example, leading to quietist and/or fideist-relativist conclusions) I argue that the distinctly ethical conception of religion (specifically Christianity) that (...) Wittgenstein presents should lead us to a quite different assessment. In particular, his preoccupation with the categorical nature of religion suggests a conception of "genuine" religious belief which disrupts both the economics of eschatological-salvationist hope, and the traditional ethical precept that "ought implies can." In short, what Wittgenstein presents is a sketch of a religion without recompense. (shrink)

This article presents a novel control approach, hybrid neuro-fuzzy, for the load frequency control of a four-area interconnected power system. The advantage of this controller is that it can handle nonlinearities, and at the same time, it is faster than other existing controllers. The effectiveness of the proposed controller in increasing the damping of local and inter-area modes of oscillation is demonstrated in a four-area interconnected power system. Areas 1 and 2 consist of a thermal reheat power plant, whereas (...) Areas 3 and 4 consist of a hydropower plant. Performance evaluation is carried out by using fuzzy, artificial neural network, adaptive neuro-fuzzy inference system, and conventional proportional and integral control approaches. Four different models with different controllers are developed and simulated, and performance evaluations are carried out with said controllers. The result shows that the intelligent HNF controller has improved dynamic response and is at the same time faster than ANN, fuzzy, and conventional PI controllers. (shrink)

A stimulating introduction to central issues of political theory, including liberty, rights and the state, and the claims of need and politics.

A short book combining extracts from the work of one of the world's greatest thinkers with commentary from one of Britain's most distinguished writers on philosophy.

Simone Weil (1909-1943) was one of the most original philosophers & political thinkers of this century. Coming to Christianity late in her short life, she offered a refreshing creativity & a rare ability to confront theological complacencies. In introducing her writings & thoughts, this book emphasizes her never-ending search for truth, a search that epitomizes twentieth-century spirituality.

There is a world-wide debate at the moment about the appropriate role for the state in modern societies in the light of the world financial crisis. This book provides a comprehensive analysis and critique of Neo-liberal or economic liberal ideas on this issue.

Widespread and lasting consensus has not been philosophy's fate. Indeed, one of philosophy's most striking features is its ability to accommodate “not only different answers to philosophical questions” but also “total disagreement on what questions are philosophical” (Rorty 1995, 58). It is therefore hardly surprising that philosophers' responses to this metaphilosophical predicament have been similarly varied. This article considers two recent diagnoses of philosophical diversity: Kornblith and Rescher (respectively) claim that taking philosophical disagreement seriously does not lead to metaphilosophical scepticism. (...) The article argues that their confidence is misplaced in so far as both wrongly assume that ordinary, first-order philosophical practice and second-order metaphilosophical reflection are separate enterprises. We can say that the universe consists of a substance, and this substance we will call “atoms,” or else we will call it “monads.” Democritus called it atoms. Leibniz called it monads. Fortunately, the two men never met, or there would have been a very dull argument. (Allen 1997, 171) When will philosophers learn to be less pretentious and arrogant in their claims? One would imagine that the philosophic experiences of twenty-five centuries would have taught them the fallacy of self-esteem! (Schilpp 1935, 233). (shrink)

Mark Dooley has recently argued (principally against Simon Critchley) that the attempt to establish too strong a ‘connection’ between Jacques Derrida and Emmanuel Levinas not only distorts crucial disparities between their respective philosophies, it also contaminates Derrida’s recent work with Levinas’s inherent ‘political naivety’.

In Culture and Value Wittgenstein remarks: ‘Thoughts that are at peace. That's what someone who philosophizes yearns for’. The desire for such conceptual tranquillity is a recurrent theme in Wittgenstein's work, and especially in his later ‘grammatical-therapeutic’ philosophy. Some commentators (notably Rush Rhees and C. G. Luckhardt) have cautioned that emphasising this facet of Wittgenstein's work ‘trivialises’ philosophy – something which is at odds with Wittgenstein's own philosophical ‘seriousness’ (in particular his insistence that philosophy demands that one ‘Go the bloody (...) hard way’). Drawing on a number of correlations between Wittgenstein's conception of philosophy and that of the Pyrrhonian Sceptics, in this paper I defend a strong ‘therapeutic’ reading of Wittgenstein, and show how this can be maintained without ‘trivialising’ philosophy.

The paper explicates Bonhoeffer's dense statement, made in a 1932 lecture, that `Reality is the sacrament of [the ethical] command'. It begins with a summary of William T. Cavanaugh's rich description of the Eucharist as that act which makes the Church Christ's body, thereby constituting the true res publica.
