Law and Society, Third Edition, offers a contemporary overview of the structure and function of legal institutions, along with a lively discussion of both criminal and civil law and their impact on society. Unlike other books on law and society, Matthew Lippman takes an interdisciplinary approach that highlights the relevance of the law throughout our society. Distinctive coverage of diversity, inequality, civil liberties, and globalism is intertwined through an organized theme in a strong narrative. The highly anticipated Third (...) Edition of this practical and invigorating text introduces students to both the influence of law on society and the influence of society on the law. Discussions of the pressing issues facing today's society include key topics such as the law and inequality, international human rights, privacy and surveillance, and law and social control.?KEY FEATURES: An interdisciplinary approach integrates various intellectual perspectives and traditions to provide extensive coverage of the legal profession, juries, criminal courts, and racial and ethnic inequality. Gender is covered throughout the text with particular attention devoted to abortion, human trafficking, global exploitation, sexual abuse, and the role of women in the justice system. A distinction between legal myth and reality is analyzed throughout the text using contemporary media examples. International Perspective sections offer relevant cross-cultural and international studies to provide a unique global viewpoint. Test Your Knowledge questions open chapters to show students what they may and may not know prior to reading the chapters. You Decide cases are presented throughout the book to sharpen critical thinking skills by applying the chapter contents to contemporary issues. (shrink)

We defend a scalar theory of the relationship between material scarcity and justice. As scarcity increases beyond a specified threshold, we argue that deontological egalitarian constraints should be gradually relaxed and consequentialist considerations should increasingly determine distributions. We construct this theory by taking a bottom-up approach that is guided by principles of medical triage. Armed with this theory, we consider the range of conditions under which justice applies. We argue that there are compelling reasons for thinking that justice applies under (...) a far broader range of conditions than is standardly supposed, including those that could sensibly be labelled as conditions of extreme rather than moderate scarcity.

The aim of what follows is to explore how to raise the question of Being by way of Heidegger’s phenomenological ontology. Phenomenological ontology is a way of approaching and conducting philosophy exemplified in the work of German philosopher Martin Heidegger’s, and specifically in his magnum opus Being and Time. In preparation to raise the question of Being a more nuanced understanding of Heidegger’s phenomenological analyses on truth and language are summarized. Following, the manner in which Being is referenced is analyzed (...) before considering the way of Heidegger’s phenomenological ontology. In conclusion, existing attempts and continuing efforts into the question of Being in education through phenomenological ontology are shared. At a time when decontextualized and reductive ways of knowing and being are becoming the norm within education, phenomenological ontology offers new possibilities for scholarship and practice. The present inquiry does not offer solutions in the traditional sense but rather traces a path that opens and keeps in tension the question of Being in education in order to support further study.

Human cooperation is highly unusual. We live in large groups composed mostly of non-relatives. Evolutionists have proposed a number of explanations for this pattern, including cultural group selection and extensions of more general processes such as reciprocity, kin selection, and multi-level selection acting on genes. Evolutionary processes are consilient; they affect several different empirical domains, such as patterns of behavior and the proximal drivers of that behavior. In this target article, we sketch the evidence from five domains that bear on (...) the explanatory adequacy of cultural group selection and competing hypotheses to explain human cooperation. Does cultural transmission constitute an inheritance system that can evolve in a Darwinian fashion? Are the norms that underpin institutions among the cultural traits so transmitted? Do we observe sufficient variation at the level of groups of considerable size for group selection to be a plausible process? Do human groups compete, and do success and failure in competition depend upon cultural variation? Do we observe adaptations for cooperation in humans that most plausibly arose by cultural group selection? If the answer to one of these questions is “no,” then we must look to other hypotheses. We present evidence, including quantitative evidence, that the answer to all of the questions is “yes” and argue that we must take the cultural group selection hypothesis seriously. If culturally transmitted systems of rules (institutions) that limit individual deviance organize cooperation in human societies, then it is not clear that any extant alternative to cultural group selection can be a complete explanation.

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied machine learning on the multi-national data collected by the International Collaboration on the Social and Moral Psychology of COVID-19 (N = 51,404) to test the predictive efficacy of constructs from (...) social, moral, cognitive, and personality psychology, as well as socio-demographic factors, in the attitudinal and behavioral responses to the pandemic. The results point to several valuable insights. Internalized moral identity provided the most consistent predictive contribution—individuals perceiving moral traits as central to their self-concept reported higher adherence to preventive measures. Similar was found for morality as cooperation, symbolized moral identity, self-control, open-mindedness, collective narcissism, while the inverse relationship was evident for the endorsement of conspiracy theories. However, we also found a non-negligible variability in the explained variance and predictive contributions with respect to macro-level factors such as the pandemic stage or cultural region. Overall, the results underscore the importance of morality-related and contextual factors in understanding adherence to public health recommendations during the pandemic. (shrink)

Credal reductivism is the view that outright belief is reducible to degrees of confidence or ‘credence’. The most popular versions of credal reductivism all have the consequence that if you are near-maximally confident that p in a low-stakes situation, then you outright believe p. This paper addresses a recent objection to this consequence—the Correctness Objection— introduced by Jeremy Fantl and Matthew McGrath and further developed by Jacob Ross and Mark Schroeder. The objection is that near-maximal confidence cannot entail (...) outright belief because when you believe a false proposition, you are wrong or incorrect, whereas you can be highly confident of a false proposition in a low-stakes situation without being incorrect. Both Fantl and McGrath’s and Ross and Schoeder’s versions of the Correctness Objection admit of multiple interpretations. But it is argued that even on the most charitable interpretations the objection fails. (shrink)

This essay critically examines the Assurance View of testimony as put forth by Angus Ross (1986) and Richard Moran (1999). The Assurance View holds that someone who offers testimony gives the hearer a non-evidential justification for belief by assuming responsibility for the truth of her testimony. I agree that testimonial justification depends on the teller’s assumption of her responsibility for her testimony, but argue that it is nevertheless evidential justification. Testimonial justification is a sort of evidence that is within (...) the teller’s power to create or withhold at will, and that power is essential to the justification. (shrink)

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

The Assurance View, as advanced by Angus Ross and Richard Moran, makes the epistemology of testimony a matter of interpersonal commitments and entitlements. More specifically, I argue, their position is best understood as claiming that for someone’s belief to be testimonially justified is for some speaker to bear illocutionary responsibility for its truth. With this understanding in hand, I present a problem for the view that has so far escaped attention, a problem deriving from the wide freedom we have (...) to retract our assertions. Retraction dissolves the illocutionary responsibilities that were set up by preceding speech acts; but in some circumstances the epistemic significance of a retraction is effectively nil. We can therefore construct cases in which the responsibilities undertaken in testimony have been canceled, while the justification for belief based on it remains in place—and that shouldn’t be possible, if the Assurance View has things right. I present one such case and press its implications. (shrink)

The development and deployment of artificial intelligence (AI) is and will profoundly reshape human society, the culture and the composition of civilisations which make up human kind. All technological triggers tend to drive a hype curve which over time is realised by an output which is often unexpected, taking both pessimistic and optimistic perspectives and actions of drivers, contributors and enablers on a journey where the ultimate destination may be unclear. In this paper we hypothesise that this journey is not (...) dissimilar to the personal journey described by the Kubler-Ross change curve and illustrate this by commentary on the potential of AI for drug discovery, development and healthcare and as an enabler for deep space exploration and colonisation. Recent advances in the call for regulation to ensure development of safety measures associated with machine-based learning are presented which, together with regulation of the rapidly emerging digital after-life industry, should provide a platform for realising the full potential benefit of AI for the human species.

Experiences of Depression is a philosophical exploration of what it is like to be depressed. In this important new book, Matthew Ratcliffe develops a detailed account of depression experiences by drawing on work in phenomenology, philosophy of mind and psychology, and several other disciplines.

In Real Hallucinations, Matthew Ratcliffe offers a philosophical examination of the structure of human experience, its vulnerability to disruption, and how it is shaped by relations with other people. He focuses on the seemingly simple question of how we manage to distinguish among our experiences of perceiving, remembering, imagining, and thinking. To answer this question, he first develops a detailed analysis of auditory verbal hallucinations (usually defined as hearing a voice in the absence of a speaker) and thought insertion (...) (somehow experiencing one's own thoughts as someone else's). He shows how thought insertion and many of those experiences labeled as "hallucinations" consist of disturbances in a person's senseof being in one type of intentional state rather than another. Ratcliffe goes on to argue that such experiences occur against a backdrop of less pronounced but wider-ranging alterations in the structure of intentionality. In so doing, he considers forms of experience associated with trauma, schizophrenia, and profound grief. The overall position arrived at is that experience has an essentially temporal structure, involving patterns of anticipation and fulfillment that are specific to types of intentional states and serve to distinguish them phenomenologically. Disturbances of this structure can lead to various kinds of anomalous experience. Importantly, anticipation-fulfillment patterns are sustained, regulated, and disrupted by interpersonal experience and interaction. It follows that the integrity of human experience, including the most basic sense of self, is inseparable from how we relate to other people and to the social world as a whole. (shrink)

Nation and Identity provides a concise and comprehensive account of the place of national identity in modern life. Ross Poole argues that the nation became a fundamental organising principle of social, political and moral life during the period of early modernity and that is has provided the organising principle of much liberal, republican and democratic thought. Ross Poole offers us a new and urgently needed analysis of the concept of identity, arguing that we are now in a position (...) to envisage the end of nationalism. We see that the impact of issues like multiculturalism, republicanism, and indigenous rights have made it very difficult to see how the possibility of a postnational cosmopolitanism could not degenerate into a nihilistic moral universe. Nation and Identity will be a fascinating read for all those interested in issues of national identity, both politically and philosophically. (shrink)

Why do we spend so much of our time passing on amusing anecdotes, making wisecracks,watching The Simpsons? In Inside Jokes, Matthew Hurley, DanielDennett, and Reginald Adams offer an evolutionary and cognitive perspective.

Necessitarianism, as we shall use the term, is the view that natural properties and causal powers are necessarily connected in some way. In recent decades the most popular forms of necessitarianism have been the anti-Humean powers-based theories of properties, such as dispositional essentialism and the identity theory. These versions of necessitarianism have come under fire in recent years and I believe it is time for necessitarians to develop a new approach. In this paper I identify unexplored ways of positing metaphysically (...) necessary connections in nature, using the concepts of grounding and essential dependence. For example, I show that one could be a necessitarian by insisting that the properties of things necessarily ground their powers, and that one can maintain this while rejecting dispositional essentialism. Using different combinations of claims about grounding and essential dependence, I map out a spectrum of new positions and compare them to previous theories of natural modality. Some of these positions are compatible with Humean metaphysics while others are not. The overall aim of the paper is to provide a new metaphysical framework for understanding theories of powers and thereby launch a new necessitarian research programme. (shrink)

Spinoza was one of the most influential figures of the Enlightenment, but his often obscure metaphysics makes it difficult to understand the ultimate message of his philosophy. Although he regarded freedom as the fundamental goal of his ethics and politics, his theory of freedom has not received sustained, comprehensive treatment. Spinoza holds that we attain freedom by governing ourselves according to practical principles, which express many of our deepest moral commitments. Matthew J. Kisner focuses on this theory and presents (...) an alternative picture of the ethical project driving Spinoza's philosophical system. His study of the neglected practical philosophy provides an accessible and concrete picture of what it means to live as Spinoza's ethics envisioned. (shrink)

In _Camus, Philosophe: To Return to our Beginnings_ Matthew Sharpe reads Camus as a _philosophe_ in the classical and enlightenment lineages, arguing that his defense of _mesure_ singles him out amidst 20th century French thought and makes him of renewed relevance today.

This book follows postwar Germany's leading philosopher and social thinker, Jürgen Habermas, through four decades of political and constitutional struggle over the shape of liberal democracy in Germany. Habermas's most influential theories - of the public sphere, communicative action, and modernity - were decisively shaped by major West German political events: the failure to de-Nazify the judiciary, the rise of a powerful Constitutional Court, student rebellions in the late 1960s, the changing fortunes of the Social Democratic Party, NATO's decision to (...) station nuclear weapons, and the unexpected collapse of East Germany. In turn, Habermas's writings on state, law, and constitution played a critical role in reorienting German political thought and culture to a progressive liberal-democratic model. Matthew Specter uniquely illuminates the interrelationship between the thinker and his culture. (shrink)

The aim in this paper is to focus on one of the proposals about successful perception that has led its adherents to advance some kind of disjunctive account of experience. The proposal is that we should understand the conscious sensory experience involved in successful perception in relational terms. I first try to clarify what the commitments of the view are, and where disagreements with competing views may lie. I then suggest that there are considerations relating to the conscious character of (...) our perception of events that speak in its favour. (shrink)

There are ways that ethical intuitions might be, and the various possibilities have epistemic ramifications. This paper criticizes some extant accounts of what ethical intuitions are and how they justify, and it offers an alternative account. Roughly, an ethical intuition that p is a kind of seeming state constituted by a consideration whether p, attended by positive phenomenological qualities that count as evidence for p, and so a reason to believe that p. They are distinguished from other kinds of seemings, (...) such as those which are content driven (e.g., the sensory experience that a stick in water seems bent) and those which are competence driven (e.g., the intellectual seeming that XYZ is not water, or that one of DeMorgan’s laws is true). One important conclusion is this: when crafting a positive theory of justification ethical intuitionists have fewer resources than intuitionists in other domains, not because of the subject matter of ethical intuitions, but because of the their structure. A second conclusion is that the seemings featured in substantive ethical intuitions deliver relatively weak justification as compared to other seeming states. (shrink)

The paper seeks to show that underlying Bentham's concept of utility is a commitment to a criterion or principle of moral status distinguishing morally relevant beings from the morally irrelevant. Further, that the notion of moral status is ultimately inconsistent with Bentham's utility; that it implies something like a Kantian ethic barring the use of morally relevant beings as mere means to some other's satisfaction, an ethic which suitably interpreted may be more useful in defence of some concerns for which (...) Bentham has traditionally been cited, animal rights for example. The paper concludes by noting the history and politics of moral status and argues that the concept involves a fusion of fact and value, the empirical and the evaluative, undermining assumptions of a rigid separation of the two and the consequent essential subjectivity of the latter.

Platonism delivers a theory of possibility that is distinct from both Lewisian modal realism and ersatz modal theories. By putting the topic of alien properties at centre stage in our modal theorizing, a strong preliminary case for platonism can be made. A puzzle about alien properties is created by modern truthmaker theory and some plausible assumptions about properties and existence. But this puzzle is one that platonism is able to solve in a simple and conservative way.

Philosophy & Social Criticism, Volume 48, Issue 4, Page 473-483, May 2022. In my recent book Freedom of Expression as Self-Restraint, I expound and defend the moral principle of freedom of expression. This article recounts a few of the main strands of the exposition in that book, and it touches upon the justification for the principle of freedom of expression. Supplementing the abstract ideas broached in the article are several illustrative examples that render the abstractions more accessible.

Recently, Choi has argued that current accounts of intrinsically finkable dispositions lead to absurd consequences in certain everyday cases. In this paper I offer a new argument for the existence of intrinsically finkable dispositions, one which provides a new way of testing for the presence of such dispositions. It is then argued that, with this new test in place, Choi’s examples no longer present a problem for the view that some dispositions are intrinsically finkable.

Drawing on social comparison theory, we investigate employees’ ethical and performance comparisons relative to a similar coworker and subsequent emotional and behavioral responses. We test our theoretically driven hypotheses across two studies. Study 1, a cross-sectional field study, reveals that employees who perceive they are more ethical than their coworkers experience negative emotions toward the comparison coworkers and those feelings are even stronger when the employees perceive they are lower performers than their coworkers. Results also reveal that negative emotions mediate (...) the indirect relationship between being more ethical than a coworker, but also being a lower performer than that coworker onto social undermining and ostracism. Study 2, a 2 × 2 between-subjects experimental design, provides further support for our moderated mediation model. Results reveal that participants experience negative emotions when they receive information that they are more ethical than a comparison participant. Negative emotions are amplified if the participant is told they were a lower performer than the comparison participant. Those participants indicate their desire to mistreat and ignore the comparison participant if given the opportunity. Thus, we find support for our hypotheses using a multi-method design. (shrink)

Ankeny and Leonelli propose “repertoires” as a new way to understand the stability of certain research programs as well as scientific change in general. By bringing a more complete range of social, material, and epistemic elements into one framework, they position their work as a correction for the Kuhnian impulse in philosophy of science and other areas of science studies. I argue that this “post-Kuhnian” move is not complete, and that repertoires maintain an internalist perspective, caused partly by an asymmetrical (...) emphasis on the scientists’ side of practice. If we compare “repertoires” to alternative frameworks, like “sociotechnical imaginaries” of Jasanoff and Kim, it is evident that repertoires are missing two specific things. First, I argue that the framework needs to include the role of audience, without whom the repertoires of science are unintelligible. Second, I suggest that the framework also lacks an explicit place for ethical and political imagination, which provide meaning for otherwise mechanical promotion of particular research programs. With these modifications, Ankeny and Leonelli’s framework might fulfill its post-Kuhnian potential. (shrink)

This article examines how British philosophers of the 1930s grappled with the relationship between reason, emotion, and democratic citizenship in the context of a perceived “crisis of democracy” in Europe. Focusing especially on Bertrand Russell, Susan Stebbing, and John Macmurray, it argues that philosophers working from diverse philosophical perspectives shared a sense that the crisis of democracy was simultaneously a crisis of reason and one of emotion. They tended to frame this crisis in terms of three interrelated concerns: first, as (...) a problem of balancing or integrating reason and emotion; second, as a problem of the relationship between emotions and democratic citizenship; and third, as a problem of how to properly train or educate the emotions. Significantly, British philosophers addressed these issues most directly in writings for a non-professional audience, as they sought to translate their professional expertise into popular works that might rejuvenate democratic citizenship. This historical episode is a reminder of how philosophers were deeply engaged in the cultural politics of the interwar period and is a telling example of how personalist concerns were central to philosophy even as the “analytic revolution” was gathering steam.

How are law and morality connected, how do they interact, and in what ways are they distinct? In Part I of this book, Matthew Kramer argues that moral principles can enter into the law of any jurisdiction. He contends that legal officials can invoke moral principles as laws for resolving disputes, and that they can also invoke them as threshold tests which ordinary laws must satisfy. In opposition to many other theorists, Kramer argues that these functions of moral principles (...) are consistent with all the essential characteristics of any legal system. Part II reaffirms the legal positivist argument that law and morality are separable, arguing against the position of natural-law theory, which portrays legal requirements as a species of moral requirements. Kramer contends that even though the existence of a legal system in any sizeable society is essential for the realization of fundamental moral values, law is not inherently moral either in its effects or in its motivational underpinnings. In the final part, Kramer contests the widespread view that people whose conduct is meticulously careful cannot be held morally responsible for harmful effects of their actions. Through this argument, he reveals that fault-independent liability is present even more prominently in morality than in the law. Through a variety of arguments, Where Law and Morality Meet highlights both some surprising affinities and some striking divergences between morality and law. (shrink)

This research systematically evaluates via prototype analysis how conceptualizations of Western adult's monotheistic God are structured. Over 4 studies, using U.S. student and community samples of predominantly Christians, features of God are identified, feature centrality is documented, and centrality influence on cognition is evaluated. Studies 1 and 2 produced considerable overlap in feature frequency and centrality ratings across the samples, with “God is love” being the most frequently listed central feature. In Studies 3 (choice latency) and 4 (recall and recognition (...) memory), the centrality of features influenced cognitive processes: central features were more quickly identified as features of God than peripheral features; were correctly recognized more often; and central features were correctly recalled more often than peripheral features. Results indicated that participants meaningfully judged centrality and that centrality affected cognition. Thus, the two criteria necessary for demonstrating deity representations adhere to a prototype structure were met. Implications and future directions are discussed. (shrink)

Research in the neurosciences continues to provide evidence that sleep plays a role in the processes of learning and memory. There is less of a consensus, however, regarding the precise stages of memory development during which sleep is considered a requirement, simply favorable, or not important. This article begins with an overview of recent studies regarding sleep and learning, predominantly in the procedural memory domain, and is measured against our current understanding of the mechanisms that govern memory formation. Based on (...) these considerations, I offer a new neurocognitive framework of procedural learning, consisting first of acquisition, followed by two specific stages of consolidation, one involving a process of stabilization, the other involving enhancement, whereby delayed learning occurs. Psychophysiological evidence indicates that initial acquisition does not rely fundamentally on sleep. This also appears to be true for the stabilization phase of consolidation, with durable representations, resistant to interference, clearly developing in a successful manner during time awake (or just time, per se). In contrast, the consolidation stage, resulting in additional/enhanced learning in the absence of further rehearsal, does appear to rely on the process of sleep, with evidence for specific sleep-stage dependencies across the procedural domain. Evaluations at a molecular, cellular, and systems level currently offer several sleep specific candidates that could play a role in sleep-dependent learning. These include the upregulation of select plasticity-associated genes, increased protein synthesis, changes in neurotransmitter concentration, and specific electrical events in neuronal networks that modulate synaptic potentiation. Key Words: consolidation; enhancement; learning; memory; plasticity; sleep; stabilization. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 11.1 (2004) 35-41 [Access article in PDF] The Rationality of Psychosis and Understanding the Deluded Matthew R. Broome Campbell's important and influential paper (Campbell 2001) has framed the debate that Bayne and Pacherie (2004) most explicitly, and Klee (2004) and Georgaca (2004) more implicitly, engage in. Campbell has offered two broad ways of thinking about explanations of delusions—the empirical and the rational. He offers (...) some criticism of the former and an endorsement of the latter. Campbell uses examples from clinical psychopathology to illustrate his argument and Bayne and Pacherie in turn employ these. Campbell discusses the eponymously named delusions of Capgras and Cotard—the former a subtype of delusional misidentification and the latter a delusion whose content is colored predominantly with nihilistic and possibly hypochondriacal themes. Campbell, Bayne and Pacherie, and Klee discuss the empirical data in relation to such delusions and as an aid to discussing the empirical model more generally. It does seem a little unfortunate that these delusions, which are less than typical, become the focus of Campbell's paper, and Bayne and Pacherie's criticism of his work. Delusions are remarkably heterogeneous; this indeed may be part of the reason why there is so much difficulty in reaching a definition as Klee discusses, and occur in a wide variety of mental and neurological illnesses. The most common delusions are those of persecution and reference (World Health Organization [WHO] 1973) and typically occur in schizophrenia. By contrast, delusional misidentification occurs most commonly in patients with dementia, delirium, and focal cognitive impairment, but can occur in other functional psychoses such as an affective or schizophrenic psychosis. The most common form of delusional misidentification is not that of either the exotic Capgras or Fregoli syndromes but delusional misidentification for place; thus, although Bayne and Pacherie's arguments against Campbell may still hold, delusional misidentification tends to occur in the context of a patient believing that they are at home or on holiday rather than in hospital and may not necessarily involve close family members or other intimate relationships. Similarly, Cotard's syndrome tends to occur in the context of a severe depressive illness with mood-congruent psychotic symptoms, typically in an elderly individual. It does not have to have the content that the deluded is dead, but can include beliefs, for example, that the world no longer exists or that their internal organs are not present. Thus, a patient with either Capgras' or Cotard's syndrome is likely to differ from patients with delusions of persecution. They would [End Page 35] have different diagnoses, probably be older, and have a greater likelihood of structural abnormalities of the brain on imaging and consequent neuropsychological dysfunction. That is not to say that patients with schizophrenia have normal cerebral anatomy and neuropsychology, but rather that the Capgras' and Cotard's patients are likely to have neurological quality to their presentation that is clinically relevant, rather than what commonly the case in schizophrenia and the other functional psychoses, where the neurological abnormalities are only currently important at the level of academic research. Empirical Models of Delusion Formation Different delusions may not have that much in common, nor may the patients who believe in them. This in turn relates to the empirical paradigm that both Campbell and Bayne and Pacherie discuss. It is true that current research, and indeed the clinical practice of cognitive behavioral therapy for psychosis, is indebted to the work of Maher and it is within his legacy which we work. This, however, is not to say that we think his initial formulation was correct. Maher's (1988, 1992) work focused attempts in explaining delusions—both to support and refute his thesis that delusions are the consequence of normal cognitive mechanisms seeking to explain an anomalous sensory experience. Such a view initially led to work demonstrating delusions in the absence of anomalous perceptions, the presence of reasoning biases in the deluded population, and the possibility that abnormal sensory experience may be consequent upon biased cognitive processes (Garety and Freeman 1999). More recent work has demonstrated the prevalence of... (shrink)

Plant predictive processing suggests that plants anticipatorily perceive their environment. This hypothesis runs up against a challenge which takes the form of two constraints on per- ception advanced by Tyler Burge: the veridicality constraint and the constancy constraint. This paper argues that the veridicality constraint can be satisfied by assuming a general account of predictive processing. To show how the constancy constraint may be fulfilled, an ecologically informed account of invariant pick-up is developed and given a place within plant predictive (...) processing. It is concluded that, against our anthro- pocentric folk-psychological notions of perception, there is reason to believe that plants engage in minimal perception. (shrink)
