'Practices without foundations' is, in genesis and in effect, a discussion of the following quotation , which serves therefore as an epigraph to it: ;Nelson Goodman's discussion of the 'new riddle of induction' ... deserves comparison with Wittgenstein's work. Indeed ... the basic strategy of Goodman's treatment of the 'new riddle' is strikingly close to Wittgenstein's sceptical arguments .... Although our paradigm of Wittgenstein's problem was formulated for a mathematical problem it ... is completely general and can be applied to (...) any rule or word. In particular, if it were formulated for the language of color impressions, as Wittgenstein himself suggests, Goodman's 'grue', or something similar, would play the role of 'quus'. But the problem would not be Goodman's about induction--"Why not predict that grass, which has been grue in the past will be grue in the future?"--but Wittgenstein's about meaning: "Who is to say that in the past I didn't mean grue by 'green', so that now I should call the sky, not the grass, 'green'?" vskip9pt ;This fascinating remark of Kripke's suggests a project, that of charting out both the interpretive and philosophic points of connection and disconnection between Wittgenstein, Goodman and Kripke. That project is this dissertation. ;My work severely tests Kripke's remark. For I argue that Kripke not only misreads Wittgenstein, but also mistakes the extremity of the 'scepticism' of his version of Wittgenstein for the priority of the philosophical puzzle that Goodman has bequeathed to us. ;To reach this conclusion, I show that Kripke's Wittgenstein's 'meaning-scepticism' is unanswerable if statable, but actually unstatable; and that, under certain interpretations, the same is true of putative scepticisms derivable from Goodman's text. The upshot is that the sceptical reading of most twentieth century philosophy must be displaced in favour of 'post-scepticism' and 'philosophical ethnography'. The latter concepts, sketched toward the end of the dissertation, are perhaps its telos. (shrink)

In this book, Rupert Read offers the first outline of a resolute reading, following the highly influential New Wittgenstein 'school', of the Philosophical Investigations. He argues that the key to understanding Wittgenstein's later philosophy is to understand its liberatory purport. Read contends that a resolute reading coincides in its fundaments with what, building on ideas in the later Gordon Baker, he calls a liberatory reading. Liberatory philosophy is philosophy that can liberate the user from compulsive patterns of (...) thought, freeing one for possibilities that were previously obscured. Such liberation is our prime goal in philosophy. This book consists in a sequential reading, along these lines, of what Read considers the most important and controversial passages in the Philosophical Investigations 1, 16, 43, 95 & 116 & 122, 130-3, 149-151, 186, 198-201, 217, and 284-6. Read claims that this liberatory conception is simultaneously an ethical conception. The PI should be considered a work of ethics in that its central concern becomes our relation with others. Wittgensteinian liberations challenge widespread assumptions about how we allegedly are independent of and separate from others. Wittgenstein's Liberatory Philosophy will be of interest to scholars and advanced students working on Wittgenstein, and to scholars of the political philosophy of liberation and the ethics of relation.

For Knox, ‘spacetime’ is to be defined functionally, as that which picks out a structure of local inertial frames. Assuming that Knox is motivated to construct this functional definition of spacetime on the grounds that it appears to identify that structure which plays theoperationalrole of spacetime—i.e., that structure which is actually surveyed by physical rods and clocks built from matter fields—we identify in this paper important limitations of her approach: these limitations are based upon the fact that there is a (...) gap between inertial frame structure and that which is operationally significant in the above sense. We present five concrete cases in which these two notions come apart, before considering various ways in which Knox’s spacetime functionalism might be amended in light of these issues. (shrink)

Climate change and the destruction of the earth is the most urgent issue of our time. We are hurtling towards the end of civilisation as we know it. With an unflinching honest approach, Rupert Read asks us to face up to the fate of the planet. This is a book for anyone who wants their philosophy to deal with reality and their climate concern to be more than a displacement activity. -/- As people come together to mourn the loss of (...) the planet, we have the opportunity to create a grounded, hopeful response. This meaningful hopefulness looks to the new communities created around climate activism. Together, our collective mourning enables us to become human in ways previously unknown. -/- Why Climate Breakdown Matters is a practical guide on how to be a radical, responsible climate activist.

Inspired by the philosophy of Wittgenstein and his idea that the purpose of real philosophical thinking is not to discover something new, but to show in a strikingly different light what is already there, this book provides philosophical readings of a number of ‘arthouse’ and Hollywood films. Each chapter contains a discussion of two films—one explored in greater detail and the other analyzed as a minor key which reveals the possibility for the book's ideas to be applied across different films, (...) registers, and genres. The readings are not only interpretive, but they offer a way of thinking and feeling about, with, and through films which is genuinely transformative. Rupert Read’s main contention is that certain films can bring about a change in how we see the world. He advocates an ecological approach to film-philosophy analysis, arguing that film can re-shape the viewer’s relationship to the environment and other living beings. The transformative 'wake-up call' of these films is enlightenment in its true sense. The result is a book that ambitiously aims to change, though film, how we think of ourselves and our place in the world, at a time when such change is more needed than ever before. (shrink)

We explore the significance of physical theories set in Euclidean spacetimes. In particular, we explore the use of these theories in contemporary physics at large, and the sense in which there can be a notion of temporal evolution in these theories. Having achieved these tasks, we proceed to reflect on the lessons that one can take from such theories for Knox’s ‘inertial frame’ version of spacetime functionalism, which seems to issue incorrect verdicts in the case of theories with Euclidean metrical (...) structure.

In the Theological-Political Treatise, published in 1670, Spinoza asked why people “fight for their servitude as if for salvation.” In doing so, he foregrounded the affective dimension of despotism, putting forward the idea that servitude is not just passively endured but passionately strived for—something people want and will. Three hundred years later, Gilles Deleuze and Félix Guattari repeated this formula in Anti-Oedipus, arguing that it was the central question of political philosophy. They read Spinoza through Wilhelm Reich, stating that the (...) astonishing thing is that “those who are exploited are not continually out on strike.” In doing so they shifted the political question from domination to exploitation. Following Deleuze and Guattari, I argue for an updated version of the question, asking why people fight for exploitation as if it were rebellion. Asking this question involves reexamining the way in which the critique of religion is the antechamber of the critique of political economy in Marx, and is the thread connecting Spinoza to Marx. Finally, I argue that reframing the question in terms of rebellion and exploitation is useful in making sense of contemporary forms of right populism that present themselves as rebellion, but actually deepen the domination of capitalism over our lives.

The equivalence principle has constituted one of the cornerstones of discussions in the foundations of spacetime theories over the past century. However, up to this point the principle has been considered overwhelmingly only within the context of relativistic physics. In this article, we demonstrate that the principle has much broader, super-theoretic significance: to do so, we present a unified framework for understanding the principle in its various guises, applicable to both relativistic and Newtonian contexts. We thereby deepen significantly our understanding (...) of the role played by the equivalence principle in a broad class of spacetime theories. (shrink)

"The Politics of Transindividuality" proposes a new understanding of not just the relation of the individual to the collective, but of politics and economics, one that can not only keep pace with existing transformations of capital but ultimately contest them.

The Oxford Calculator Roger Swyneshed put forward three provocative claims in his treatise on insolubles, written in the early 1330s, of which the second states that there is a formally valid inference with true premises and false conclusion. His example deployed the Liar paradox as the conclusion of the inference: ‘The conclusion of this inference is false, so this conclusion is false’. His account of insolubles supported his claim that the conclusion is false, and so the premise, referring to the (...) conclusion, would seem to be true. But what is his account of validity that can allow true premises to lead to a false conclusion? This article considers Roger’s own account, as well as that of Paul of Venice, writing some sixty years later, whose account of the truth and falsehood of insolubles followed Roger’s closely. Paul endorsed Roger’s three claims. But their accounts of validity were different. The question is whether these accounts are coherent and support Paul’s claim in his Logica Magna that he endorsed all the normal rules of inference. (shrink)

That our ecological future appears grave can no longer come as any surprise. And yet we have so far failed, collectively and individually, to begin the kind of action necessary to shift our path away from catastrophic climate collapse. -/- In this stark and startling little book, Rupert Read helps us to understand the direness of our predicament while showing us a metaphor and a method — a way of thinking — by which we might transform it. From the relatively (...) uncontroversial starting point that we love our own children, we are introduced to a logic of care that iterates far into the future: in caring for our own children, we are committed to caring for the whole of human future; in caring for the whole of human future, we are committed to caring for the future of the natural world. Out of such thinking, hope emerges. -/- As Read demonstrates in this urgent call to action, accepting that we care for our own offspring commits us to a struggle on behalf of us all. (shrink)

The evolution from pre-human primates to modern Homo sapiens is a complex one involving many domains, ranging from the material to the social to the cognitive, both at the individual and the community levels. This article focuses on a critical qualitative transition that took place during this evolution involving both the social and the cognitive domains. For the social domain, the transition is from the face-to-face forms of social interaction and organization that characterize the non-human primates that reached, with Pan, (...) a hiatus due to the centripetal effects that highly individualized behavior has on a social system. The transition is to the relation-based forms of social organization that evolved in the hominins ancestral to Homo sapiens and are universal in human societies today. For the cognitive domain, this transition involves going from behavior responding mainly to phenomenal level sensory inputs to behavior formed in accordance with the concept of a relation, initially abstracted from behavior patterns, then extending the concept of a relation beyond abstraction from behavior patterns to the concept of a relation generated recursively through constructing the relation of a relation. This extension made possible the construction of systems of relations; initially genealogical systems of relations constructed culturally using the logic of recursion, and subsequently, the symbolic, computational systems of kin term relations referred to by anthropologists as kinship terminologies. The latter are “constructed realities” in the sense this term is used by cultural anthropologists. It follows that the evolution of relation-based systems of social interaction is not adequately accounted for through population model evolutionary accounts such as the Dual Inheritance Theory of human evolution since “constructed realities” constitute collectively and publicly shared cultural knowledge rather than the individually and privately possessed knowledge that is assumed in the population model framework for human evolution.

Historically, a great deal of attention has been addressed to the question of what it would take to test experimentally the metrical structure of spacetime. Arguably, however, consideration of this question has been at the expense of comparable investigations into what it would take to test other structural features of spacetime. In this article, we critique and expand substantially upon an article by Hadley (Hadley in Class Quantum Gravity, 19:4565–4571, 2002), which constitutes one of the best-known paper-length studies of what (...) it would take to test the orientability of spacetime. In so doing, we seek to clarify a number of matters which remain unclear in the wake of Hadley’s article, thereby allowing the literature on this topic to progress. More positively, we also present, compare, and evaluate a number of other potential approaches to testing the orientability of spacetime which have arisen in the recent physics literature. (shrink)

The logician's central concern is with the validity of argument. A logical theory ought, therefore, to provide a general criterion of validity. This book sets out to find such a criterion, and to describe the philosophical basis and the formal theory of a logic in which the premises of a valid argument are relevant to its conclusion. The notion of relevance required for this theory is obtained by an analysis of the grounds for asserting a formula in a proof.

This article develops the philosophical work of Joanna Macy. It argues that ecological grief is a fitting response to our ecological predicament and that much of the ‘mental ill health’ that we are now seeing is, in fact, a perfectly sane response to our ecological reality. This paper claims that all ecological emotions are grounded in love/compassion. Acceptance of these emotions reveals that everything is fine in the world as it is, providing that we accept our ecological emotions as part (...) of what is ‘in the world’. This is non-dualistic acceptance or ‘fierce’ acceptance. This paper focuses primarily on the revolutionary qualities of ecological grief: a paradoxical revolution, coming as it does from a profound process of acceptance. (shrink)

In this book, Stephen Read sets out to rescue logic from its undeserved reputation as an inflexible, dogmatic discipline by demonstrating that its technicalities and processes are founded on assumptions which are themselves amenable to philosophical investigation. He examines the fundamental principles of consequence, logical truth and correct inference within the context of logic, and shows that the principles by which we delineate consequences are themselves not guaranteed free from error. Central to the notion of truth is the beguiling issue (...) of paradox. Its philosophical value, Read shows, lies in exposing the invalid assumption on which the paradox is built. Thinking About Logic also discusses logical puzzles which introduce questions relating to language, the world, and their relationship. (shrink)

Affective polarization is characterized by deep antagonism between political opponents and is an issue of growing concern. Some philosophers have recently suggested empathy as a possible remedy. In particular, it has been suggested that empathy might mitigate the harm resulting from affective polarization by helping us find common ground across our differences. While these discussions provide a helpful starting point, important questions regarding the conditions under which empathizing and finding common ground are morally appropriate and likely to be useful, given (...) the many risks associated with taking this approach, remain unaddressed. In this paper, I therefore give an account of the risks that we must reckon with if empathy and common ground are to help remedy affective polarization and repair damaged relations between political opponents. Far from suggesting that empathy is morally unimportant or intrinsically harmful, my goal is thus to extend and amplify previous discussion to promote a more nuanced understanding of empathy's role in this important aspect of the moral life and to ensure that our efforts to empathize are appropriate and fruitful.

There exists a common view that for theories related by a ‘duality’, dual models typically may be taken ab initio to represent the same physical state of affairs, i.e. to correspond to the same possible world. We question this view, by drawing a parallel with the distinction between ‘interpretational’ and ‘motivational’ approaches to symmetries.

Roger Swyneshed, in his treatise on insolubles, dating from the early 1330s, drew three notorious corollaries from his solution. The third states that there is a contradictory pair of propositions both of which are false. This appears to contradict what Whitaker, in his iconoclastic reading of Aristotle’s De Interpretatione, dubbed “The Rule of Contradictory Pairs”, which requires that in every such pair, one must be true and the other false. Whitaker argued that, immediately after defining the notion of a (...) contradictory pair, in which one statement affirms what the other denies of the same thing, Aristotle himself gave counterexamples to the rule. This gives some credence to Swyneshed’s claim that his solution to the logical paradoxes is not contrary to Aristotle’s teaching, as many of Swyneshed’s contemporaries claimed. Insolubles are false, he said, because they falsify themselves; and their contradictories are false because they falsely deny that the insoluble itself is false. Swyneshed’s solution depends crucially on the revision he makes to the acount of truth and falsehood, brought out in his first thesis: that a false proposition can signify as it is, or as Paul of Venice, who took up and developed Swyneshed’s solution some sixty years later, puts it, a false proposition can have a true significate. Swyneshed gave a further counterexample to when he claimed that some insolubles, like future contingents, are neither true nor false. Dialetheism, the contemporary claim that some propositions are both true and false, is wedded to the Rule, and in consequence divorces denial from the assertion of the contradictory negation. Consequently, Swyneshed’s logical heresy is very different from that found in dialetheism. (shrink)

Since the mid-1800s, clergy, doctors, other clinicians, and military personnel who specifically facilitate their work have been designated “non-combatants”, protected from being targeted in return for providing care on the basis of clinical need alone. While permitted to use weapons to protect themselves and their patients, they may not attempt to gain military advantage over an adversary. The rationale for these regulations is based on sound arguments aimed both at reducing human suffering, but also the ultimate advantage of the nation-state (...) fielding non-combatant staff. However, this is sometimes not immediately apparent to combatant colleagues. Clinicians in the armed force are also military officers, owing a “dual loyalty” that can create conflict if their non-combatant status is not well understood. Historical examples of doctors breaching their responsibilities include prioritisation of combat capability over the rights of individual soldiers (as occurred when scarce medical resources were allocated to soldiers more likely to return to battle in preference to those most likely to die without them), use of physicians to facilitate prisoner interrogation, medical research or treatment to enhance physical performance at the expense of health, application of Medical Rules of Eligibility according to factors other than clinical need, provision of treatment contingent upon support for military objectives, and use of medical knowledge to enhance weapons. However, not being a combatant party to a conflict does not imply that the non-combatant clinician cannot act in the national interest. Indeed, by adhering to the same universal ethics as their civilian colleagues, military clinicians provide optimal care to their own troops, facilitate freedom of action in host nations, and build positive international relationships during the conflict and in the post-conflict state.

Does the gravitational field described in general relativity possess genuine stress-energy? We answer this question in the affirmative, in a weak sense applicable in a certain class of frames of a certain class of models of the theory, and arguably also in a strong sense, applicable in all frames of all models of the theory. In addition, we argue that one can be a realist about gravitational stress-energy in general relativity even if one is a relationist about spacetime ontology. In (...) each case, our reasoning rests upon a functionalist approach to the definition of physical quantities. (shrink)

Philosophy for Life is a bold call for the practice of philosophy in our everyday lives. Philosopher and writer Rupert Read explores a series of important and often provocative contemporary political and cultural issues from a philosophical perspective, arguing that philosophy is not a body of doctrine, but a practice, a vantage point from which life should be analysed and, more importantly, acted upon. -/- Philosophy for Life is a personal journey that explores four key areas of society today: Politics, (...) Religion, Art, and the Environment. Taking tangible examples from modern politics, from climate change to the war on terror, and culture, from Peter Jackson's Lord of the Rings film trilogy to the poetry of T.S. Eliot, Read shows that philosophy is already an active part of today's world. This captivating and timely book offers a philosophical response to some of the key questions facing today's society and encourages us to use philosophy as a kind of therapy. Philosophy for Life shows that we can improve our perspective on the world and our place in it by doing philosophy everyday. (shrink)

_ Source: _Page Count 21 Ian Rumfitt has recently drawn our attention to a couple of paradoxes of signification, claiming that although Thomas Bradwardine’s “multiple-meanings” account of truth and signification can solve the first of them, it cannot solve the second. The paradoxes of signification were in fact much discussed by Bradwardine’s successors in the fourteenth century. Bradwardine’s solution appears to turn on a distinction between the principal and the consequential signification of an utterance. However, although such a distinction played (...) an important role in his successors’ theories, it is shown that Bradwardine’s account of signification does not admit any such distinction, no part being prior to the others. Accordingly his solution, unlike those of his successors, does not fall prey to Rumfitt’s paradoxes. (shrink)

Let's escape our caves and, quite literally, spend more time philosophizing in the great outdoors.

Interventions designed to promote perspective taking are increasingly prevalent in educational settings, and are also being considered for applications in other domains. Thus far, these perspective-taking interventions (PTIs) have largely escaped philosophical attention, however they are sometimes prima facie morally problematic in at least two respects: they are neither transparent nor easy to resist. Nontransparent or hard-to-resist PTIs call for a moral defense and our primary aim in this paper is to provide such a defense. We offer two arguments for (...) the view that an exemplar PTI is morally permissible even though it is plausibly neither transparent nor easy to resist. The first argument appeals to an analogy between PTIs and permissible deceptive research practices. The second appeals to the way in which PTIs draw participants’ attention to their reasons for action. We also respond to the objection that, by imposing a particular conception of the good, PTIs violate liberal neutrality. (shrink)

In his Quadratura, Paul of Venice considers a sophism involving time and tense which appears to show that there is a valid inference which is also invalid. Consider this inference concerning some proposition A : A will signify only that everything true will be false, so A will be false. Call this inference B. A and B are the basis of an insoluble-that is, a Liar-like paradox. Like the sequence of statements in Yablo's paradox, B looks ahead to a moment (...) when A will be false, yet that moment may never come. In the Quadratura, Paul follows the solution to insolubles found in the collection of elementary treatises known as the Logica Oxoniensis, which posits an implicit assertion of its own truth in insolubles like B. However, in the treatise on insolubles in his Logica Magna, Paul develops and endorses a different solution that takes insolubles at face value. We consider how both types of solution apply to A and B : on both, B is valid. But on one, B has true premises and false conclusion, and contradictories can be false together; on the other (following the Logica Oxoniensis), the counterexample is rejected. (shrink)

Jan Lukasiewicz's treatise on Aristotle's Syllogistic, published in the 1950s, has been very influential in framing contemporary understanding of Aristotle's logical systems. However, Lukasiewicz's interpretation is based on a number of tendentious claims, not least, the claim that the syllogistic was intended to apply only to non-empty terms. I show that this interpretation is not true to Aristotle's text and that a more coherent and faithful interpretation admits empty terms while maintaining all the relations of the traditional square of opposition.

We approach the physics of \emph{minimal coupling} in general relativity, demonstrating that in certain circumstances this leads to violations of the \emph{strong equivalence principle}, which states that, in general relativity, the dynamical laws of special relativity can be recovered at a point. We then assess the consequences of this result for the \emph{dynamical perspective on relativity}, finding that potential difficulties presented by such apparent violations of the strong equivalence principle can be overcome. Next, we draw upon our discussion of the (...) dynamical perspective in order to make explicit two `miracles' in the foundations of relativity theory. We close by arguing that the above results afford us insights into the nature of special relativity, and its relation to general relativity. (shrink)

Over fifteen years have passed since Cora Diamond and James Conant turned Wittgenstein scholarship upside down with the program of “resolute” reading, and ten years since this reading was crystallized in the major collection _The New Wittgenstein_.

Showcasing one piece alternately from each “camp”, _Beyond the Tractatus Wars_ (...) pairs newly commissioned pieces addressing differing views on how to understand early Wittgenstein, providing for the first time an arena in which the debate between “strong” resolutists, “mild” resolutists and “elucidatory” readers of the book can really take place. The collection includes famous “samizdat” essays by Warren Goldfarb and Roger White that are finally seeing the light of day. (shrink)

Disney represents a mythology that is universal because they are rapidly acquiring every possible alternate reality that one cares to enter, except for the sexual realm and the Christian religion realm.

I discuss the debate between dynamical versus geometrical approaches to spacetime theories, in the context of both special and general relativity, arguing that the debate takes a substantially different form in the two cases; different versions of the geometrical approach—only some of which are viable—should be distinguished; in general relativity, there is no difference between the most viable version of the geometrical approach and the dynamical approach. In addition, I demonstrate that what have previously been dubbed two ‘miracles’ of general (...) relativity admit of no resolution from within general relativity, on either the dynamical or ‘qualified’ geometrical approaches, modulo some possible hints that the second ‘miracle’ may be resolved by appeal to recent results regarding the ‘geodesic principle’ in GR.

Now that the opportunity to build back from COVID in an intelligent and thoughtful way has largely passed us by, how do we cope with the existential threat of ecological collapse? We posit that economic concerns have been granted undeserved weight in conversations around climate policy, while the role of philosophy has thus far been an untapped resource of potentially liberating knowledge that can inspire action and a deliberative, collective reconsideration of what parts of society should be valued.

Anti-exceptionalism about logic is the doctrine that logic does not require its own epistemology, for its methods are continuous with those of science. Although most recently urged by Williamson, the idea goes back at least to Lakatos, who wanted to adapt Popper's falsicationism and extend it not only to mathematics but to logic as well. But one needs to be careful here to distinguish the empirical from the a posteriori. Lakatos coined the term 'quasi-empirical' `for the counterinstances to putative mathematical (...) and logical theses. Mathematics and logic may both be a posteriori, but it does not follow that they are empirical. Indeed, as Williamson has demonstrated, what counts as empirical knowledge, and the role of experience in acquiring knowledge, are both unclear. Moreover, knowledge, even of necessary truths, is fallible. Nonetheless, logical consequence holds in virtue of the meaning of the logical terms, just as consequence in general holds in virtue of the meanings of the concepts involved; and so logic is both analytic and necessary. In this respect, it is exceptional. But its methodologyand its epistemology are the same as those of mathematics and science in being fallibilist, and counterexamples to seemingly analytic truths are as likely as those in any scientic endeavour. What is needed is a new account of the evidential basis of knowledge, one which is, perhaps surprisingly, found in Aristotle. (shrink)

In a recent article in this journal, Sus purports to account for what have been identified as the ‘two miracles’ of general relativity—that (1) the local symmetries of all dynamical equations for matter fields coincide, and (2) the symmetries of the dynamical equations governing matter fields coincide locally with the symmetries of the metric field—by application of the familiar result that every symmetry of the action is also a symmetry of the resulting equations of motion. In this reply, we argue (...) that, while otherwise exemplary in its clarity, Sus’ paper fails in this regard, for it rests upon a illegitimate application of the aforementioned result. Thus, we conclude, pace Sus, that these two miracles persist in general relativity. (shrink)

A key development in Wittgenstein Studies over recent years has been the advancement of a resolutely therapeutic reading of the Tractatus. Rupert Read offers the first extended application of this reading of Wittgenstein, encompassing Wittgenstein's later work too, to examine the implications of Wittgenstein's work as a whole upon the domains especially of literature, psychopathology, and time. Read begins by applying Wittgenstein's remarks on meaning to language, examining the consequences our conception of philosophy has for the ways in (...) which we talk about meaning. He goes on to engage with literary texts as Wittgensteinian, where 'Wittgensteinian' does not mean expressive of a Wittgenstein philosophy, but involves the literature in question remaining enigmatic, and doing philosophical work of its own. He considers Faulkner's work as productive too of a broadly Wittgensteinian philosophy of psychopathology. Read then turns to philosophical accounts of time, finding a link between the division of time into discrete moments and solipsism of the present moment as depicted in philosophy on the one hand and psychopathological states on the other.
