Folie à deux is the transference of delusional ideas from one 'primary' individual to one or more 'secondary' individuals (Lasègue & Falret, 1877). However, it is difficult to investigate experimentally because often only one patient is identified as delusional. We investigated whether hypnosis could model the experiences of the secondary in this delusion. Our primary was a confederate, who displayed two delusional beliefs and attempted to transmit them to hypnotised subjects. We manipulated the status of the confederate so that (...) they were portrayed as either "credible" or merely "interesting". Many high hypnotisable individuals adopted the confederate's beliefs and confabulated evidence in support of them. Also, subjects who interacted with a credible confederate extended their delusions beyond those displayed by the confederate. We discuss the strengths and limitations of this approach and suggest ways to improve the validity of this model. (shrink)

These few pages will attempt to analyze the relationships created in the chronically delirious person between himself and his own biography, such as he knows and has experienced it, to which he attaches himself and which dominates him without his knowing it. A few remarks to clarify our vocabulary before getting into the development of this question. We prefer the expression “chronic deliria“, in the plural, to the word “psychosis”, used in the singular. The former term is clinical, and therefore (...) empirical, whereas the second derives from theories; and, especially, the former does not immediately imply a unity of process as opposed to the effective diversity of semiotic appearances. Moreover, the nominal adjective “psychotic“ runs the risk of both clandestinely bringing in hidden presuppositions and of re-establishing the old presumed unity with mental alienation, which had, indeed, been exorcised by J. P. Falret by the middle of the nineteenth century. (shrink)

How do thought and language manage to be 'about' aspects of the world? J. Robert G. Williams investigates how representation arises out of a fundamentally non-representational world, showing the explanatory relations between the representational properties of language, of thought, and of perception and intention.

A new way to transpose the virtue epistemologist’s ‘knowledge = apt belief’ template to the collective level, as a thesis about group knowledge, is developed. In particular, it is shown how specifically judgmental belief can be realised at the collective level in a way that is structurally analogous, on a telic theory of epistemic normativity (e.g., Sosa 2020), to how it is realised at the individual level—viz., through a (collective) intentional attempt to get it right aptly (whether p) by alethically (...) affirming that p. An advantage of the proposal developed is that it is shown to be compatible with competing views—viz., joint acceptance accounts and social-distributive accounts—of how group members must interact in order to materially realise a group belief. I conclude by showing how the proposed judgment-focused collective (telic) virtue epistemology has important advantages over a rival version of collective virtue epistemology defended in recent work by Jesper Kallestrup (2016).

Strange inversions occur when things work in ways that turn received wisdom upside down. Hume offered a strangely inverted story about causation, and Darwin, about apparent design. Dennett suggests that a strange inversion also occurs when we project our own reactive complexes outward, painting our world with elusive properties like cuteness, sweetness, blueness, sexiness, funniness, and more. Such properties strike us as experiential causes, but they are really effects—a kind of shorthand for whole sets of reactive dispositions rooted in the (...) nuts and bolts of human information processing. Understanding the nature and origins of that strange inversion, Dennett believes, is thus key to understanding the nature and origins of human experience itself. This paper examines this claim, paying special attention to recent formulations that link that strange inversion to the emerging vision of the brain as a Bayesian estimator, constantly seeking to predict the unfolding sensory barrage.

It is argued that trust is a performative kind and that the evaluative normativity of trust is a special case of the evaluative normativity of performances generally. The view is shown to have advantages over competitor views, e.g., according to which good trusting is principally a matter of good believing (e.g., Hieronymi, 2008; McMyler, 2011), or good affect (e.g., Baier, 1986; Jones, 1996), or good conation (e.g., Holton, 1994). Moreover, the view can be easily extended to explain good (and bad) (...) distrust, where the latter is understood as aimed (narrow-scoped) forbearance from trusting. The overarching framework—which assimilates the evaluative norms of trusting (and distrusting) to performance-theoretic norms—supplies us with an entirely new lens to view traditional philosophical problems about what is involved in trusting and distrusting well and badly, and thus, places our capacity to make progress on problems in this area on a new footing.

The meta-problem is 'the problem of explaining why we think that there is a problem of consciousness' (Chalmers, 2018, p. 6). This presupposes that we think there is a problem in the first place. We challenge the breadth of this 'we', arguing that there is already sufficient empirical evidence to cast doubt on the claim. We then add to this body of evidence, presenting the results of a new cross-cultural study extending the work of Sytsma and Machery (2010).

The conservation of energy and momentum have been viewed as undermining Cartesian mental causation since the 1690s. Modern discussions of the topic tend to use mid-nineteenth century physics, neglecting both locality and Noether’s theorem and its converse. The relevance of General Relativity has rarely been considered. But a few authors have proposed that the non-localizability of gravitational energy and consequent lack of physically meaningful local conservation laws answers the conservation objection to mental causation: conservation already fails in GR, so there (...) is nothing for minds to violate. This paper is motivated by two ideas. First, one might take seriously the fact that GR formally has an infinity of rigid symmetries of the action and hence, by Noether’s first theorem, an infinity of conserved energies-momenta. Second, Sean Carroll has asked how one should modify the Dirac–Maxwell–Einstein equations to describe mental causation. This paper uses the generalized Bianchi identities to show that General Relativity tends to exclude, not facilitate, such Cartesian mental causation. In the simplest case, Cartesian mental influence must be spatio-temporally constant, and hence 0. The difficulty may diminish for more complicated models. Its persuasiveness is also affected by larger world-view considerations. The new general relativistic objection provides some support for realism about gravitational energy-momentum in GR. Such realism also might help to answer an objection to theories of causation involving conserved quantities, because energies-momenta would be conserved even in GR. (shrink)

Autonomous Knowledge: Radical Enhancement, Autonomy, and the Future of Knowing motivates and develops a new research programme in epistemology that is centred around the concept of epistemic autonomy.

A change in sense of self is an outcome commonly associated with Buddhist meditation. However, the sense of self is construed in multiple ways, and which changes in self-related processing are expected, intended, or possible through meditation is not well understood. In a qualitative study of meditation-related challenges, six discrete changes in sense of self were reported by Buddhist meditators: change in narrative self, loss of sense of ownership, loss of sense of agency, change in sense of embodiment, change in (...) self-other or self-world boundaries, and loss of sense of basic self. Changes in sense of self could be transient or enduring, positive or distressing, enhancing or impairing. These changes were also given varied appraisals, ranging from insights associated with Buddhist doctrines to psychopathologies such as depersonalization. In this study of practitioners reporting meditation-related challenges, more global changes in sense of self were associated with higher levels of impairment. These results have implications for both Buddhist meditation as well as mindfulness-based interventions. (shrink)

A plethora of normative conservation concepts have recently emerged, most of which are ill-defined: biological diversity, biological integrity, ecological restoration, ecological services, ecological rehabilitation, ecological sustainability, sustainable development, ecosystem health, ecosystem management, adaptive management, and keystone species are salient among them. These normative concepts can be organized and interpreted by reference to two new schools of conservation philosophy, compositionalism and functionalism. The former comprehends nature primarily by means of evolutionary ecology and considers Homo sapiens separate from nature. The latter comprehends (...) nature primarily by means of ecosystem ecology and considers Homo sapiens a part of nature. Biological diversity, biological integrity, and ecological restoration belong primarily in the compositionalist glossary; the rest belong primarily in the functionalist glossary. The former set are more appropriate norms for reserves, the latter for areas that are humanly inhabited and exploited. In contrast to the older schools of conservation philosophy, preservationism and resourcism, compositionalism and functionalism are complementary, not competitive and mutually exclusive. As the historically divergent ecological sciences—evolutionary ecology and ecosystem ecology—are increasingly synthesized, a more unified philosophy of conservation can be envisioned. (shrink)

Everyone interested in Arabic and Persian literature, in Islam and in comparative religion, regrets the death of Arthur J. Arberry, Sir Thomas Adams's Professor of Arabic in the University of Cambridge. Arberry combined rare human qualities and exceptional professional attainment, and this enabled him to make a unique contribution both to learning and to mutual understanding between East and West. He had a deep sense of vocation, which he brought to his unremitting labours as a skilled editor of texts, especially (...) in the field of Islamic mysticism, and as an imaginative translator of these texts of the Koran and of Arabic and Persian poetry, and as a sympathetic interpreter of Sūfism.

Here I reply to criticisms by Jeroen de Ridder and S. Kate Devitt to my "Collective (Telic) Virtue Epistemology".

Conceptual clarity is essential when engaging in dialogue to avoid unnecessary disagreement and to promote mutual understanding. In this issue devoted to clinical bioethics, the authors exemplify the virtue of careful conceptual analysis as they explore complex clinical questions regarding the essential nature of medicine, the boundaries of killing and letting die, the meaning of irreversibility in definitions of death, the argument for a right to try experimental medications, the ethical borders in complex medical billing, and the definition and modeling (...) of complex disease states.

In this provocative work, J. L. Schellenberg addresses those who, influenced by science, take a negative view of religion, thinking of it as outmoded if not decadent. He promotes the view that transcendently oriented religion is developmentally immature, showing the consilience of scientific thinking about deep time with his view. From this unique perspective, he responds to a number of influential cultural factors commonly thought to spell ill for religion, showing the changes – changes favorable to religion – that are (...) now called for in how we understand them and their proper impact. Finally, he provides a defense for a new and attractive religious humanism that benefits from, rather than being hindered by, religious immaturity. In Schellenberg's view, religion can and should become a human project as monumental as science. (shrink)

In an article in Philosophy R. G. Swinburne set out to argue that none of Hume's formal objections to the design argument ‘have any validity against a carefully articulated version of the argument’ . This, he maintained, is largely because Hume's criticisms ‘are bad criticisms of the argument in any form’ . The ensuing controversy between Swinburne and Olding 1 has focused upon the acceptable/unacceptable aspects of the dualism presupposed in Swinburne's defence of the design argument; upon whether any simplification (...) is achieved by reducing scientific explanation to agent explanation; and upon the problems which arise from taking a man's acting upon his body as the analogy for understanding a disembodied agent acting upon matter. In this article I shall refer to the Swinburne-Olding controversy when appropriate but my main concern is to return to Swinburne's original article and argue, seriatim , that Hume's individual criticisms of the design argument are for the most part a great deal more powerful than Swinburne allowed. I shall contend that cumulatively they destroy the design argument as any sort of rational foundation for theistic belief. But first I shall indicate briefly the character of the argument together with one or two of the distinctions and refinements in terms of which it has been found helpful to carry on the discussion in recent years.

This 2002 volume brings together major works by German thinkers, writing just prior to and after Kant, who were enormously influential in this crucial period of aesthetics. These texts include the first translation into English of Schiller's Kallias Letters and Moritz's On the Artistic Imitation of the Beautiful, together with translations of some of Hölderlin's most important theoretical writings and works by Hamann, Lessing, Novalis and Schlegel. In a philosophical introduction J. M. Bernstein traces the development of aesthetics from its (...) still rationalist and mimetic construction in Lessing, through the optimistic construal of art and/or beauty as the appearance of human freedom in the work of Schiller, to Hölderlin's darker vision of art as the memory of a lost unity, and the variations of that theme - of an impossible striving after the lost ideal - which are found in the work of Schlegel and Novalis.

I argue that Democritus can reasonably be regarded as a eudaimonist, though we have to be cautious, given that his work has come down to us in fragments and that some of these are rejected by some scholars. Despite these difficulties, I argue that the best interpretation of his ethical fragments overall is that he is a eudaimonist.

In this paper we study the variety of order Hilbert algebras, which is the equivalent algebraic semantics of the order implicational calculus of Bull.

Why is there a 'hard problem' of consciousness? Why do we seem unable to grasp intuitively that physical brain processes can be identical to experiences? Here I comment on the 'meta-problem' (Chalmers, 2018), based on previous ideas (Storm, 2014; 2018). In short: humans may be 'inborn dualists' ('neuroscepticism'), because evolution gave us two (types of) brain systems (or functional modes): one (Sp) for understanding relatively simple physical phenomena, and another (Sm) specialized for mental phenomena. Because Sp cannot deal with the (...) immense complexity of the brain processes underlying consciousness, it represents them as fundamentally different from nonmental physical phenomena (dualist intuition), using 'simulations' to produce 'Sm-type understanding'/predictions that seems radically different from 'Sp-type understanding'. (By analogy, different sensory modalities, handled by distinct brain systems, evoke qualitatively different experiences.) Brain systems for Sp representations of our brain processes never evolved, because they would be useless. When lacking a single 'template' matching different aspects of reality (objective vs. subjective = simulated), complementary 'models' are needed ('neuro-complementarity'), like the wave–particle duality in quantum mechanics. Thus, it seems plausible that Sp and Sm evolved because they were needed to cope with different challenges, and that 'problem intuitions' are side effects of these useful but different brain systems.

This paper critically evaluates an objection to introspective arguments for human freedom found within Spinoza's Ethics. The objection-- which we call Spinoza's dream argument -- challenges the evidentiary value of a person's experience of her own freedom by pointing out that some choices made within dreams are experienced as no less free than choices made while awake despite the fact that choices made within dreams are not free. After reconstructing Spinoza's dream argument, we critically evaluate it, concluding ultimately that it (...) fails in two respects. First, we draw upon the results of an experiment we conducted that suggests that dreamt choices are not experienced as free to the same extent as choices made while awake. Second, we argue that there is no compelling justification for the claim that choices made within dreams are not free. (shrink)
