This book examines the long term economic growth that has raised the West's material living standards to levels undreamed of by counterparts in any previous time or place. The authors argue that this growth has been driven by technological revolutions that have periodically transformed the West's economic, social and political landscape over the last 10,000 years and allowed the West to become, until recently, the world's only dominant technological force. Unique in the diversity of the analytical techniques used, the book (...) begins with a discussion of the causes and consequences of economic growth and technological change. The authors argue that long term economic growth is largely driven by pervasive technologies now known as General Purpose. They establish an alternative to the standard growth models that use an aggregate production function and then introduce the concept of GPTs, complete with a study of how these technologies have transformed the West since the Neolithic Agricultural Revolution. Early modern science is given more importance than in most other treatments and the 19th century demographic revolution is studied with a combination of formal models of population dynamics and historical analysis. The authors argue that once sustained growth was established in the West, formal models can shed much light on its subsequent behaviour. They build non-conventional, dynamic, non-stationary equilibrium models of GPT-driven growth that incorporate a range of phenomena that their historical studies show to be important but which are excluded from other GPT models in the interests of analytical tractability. The book concludes with a study of the policy implications that follow from their unique approach. (shrink)

Gottlob Frege's Grundgesetze der Arithmetik, or Basic Laws of Arithmetic, was intended to be his magnum opus, the book in which he would finally establish his logicist philosophy of arithmetic. But because of the disaster of Russell's Paradox, which undermined Frege's proofs, the more mathematical parts of the book have rarely been read. Richard G.

The book begins with an overview that introduces the Theorem and the issues surrounding it, and explores how the essays that follow contribute to our understanding of those issues.

Scaffolds are fundamental to many cellular signaling pathways. In this essay, a novel class of scaffolds are proposed, whose action bears striking resemblance to kinetic proofreading. Commonly, scaffold proteins are thought to work as tethers, bringing different components of a pathway together to improve the likelihood of their interaction. However, recent studies show that the cytoskeletal scaffold, anillin, supports contractile signaling by a novel, non‐tethering mechanism that controls the membrane dissociation kinetics of RhoA. More generally, such proof‐reading‐like scaffolds are distinguished (...) from tethers by a rare type of cooperativity, manifest as a super‐linear relationship between scaffold concentration and signaling efficiency. The evidence for this hypothesis is reviewed, its conceptual ramifications are considered, and research questions for the future are discussed. (shrink)

John Etchemendy has argued that it is but "a fortuitous accident" that Tarski's work on truth has any signifance at all for semantics. I argue, in response, that Etchemendy and others, such as Scott Soames and Hilary Putnam, have been misled by Tarski's emphasis on definitions of truth rather than theories of truth and that, once we appreciate how Tarski understood the relation between these, we can answer Etchemendy's implicit and explicit criticisms of neo-Davidsonian semantics.

Frege's intention in section 31 of Grundgesetze is to show that every well-formed expression in his formal system denotes. But it has been obscure why he wants to do this and how he intends to do it. It is argued here that, in large part, Frege's purpose is to show that the smooth breathing, from which names of value-ranges are formed, denotes; that his proof that his other primitive expressions denote is sound and anticipates Tarski's theory of truth; and that (...) the proof that the smooth breathing denotes, while flawed, rests upon an idea now familiar from the completeness proof for first-order logic. The main work of the paper consists in defending a new understanding of the semantics Frege offers for the quantifiers: one which is objectual, but which does not make use of the notion of an assignment to a free variable.

Psychoanalysis is often equated with Sigmund Freud, but this comparison ignores the wide range of clinical practices, observational methods, general theories, and cross-pollinations with other disciplines that characterise contemporary psychoanalytic work. Central psychoanalytic concepts to do with unconscious motivation, primitive forms of thought, defence mechanisms, and transference form a mainstay of today's richly textured contemporary clinical psychological practice. -/- In this landmark collection on philosophy and psychoanalysis, leading researchers provide an evaluative overview of current thinking. Written at the interface between (...) these two disciplines, the Oxford Handbook of Philosophy and Psychoanalysis contains original contributions that will shape the future of debate. With 34 chapters divided into eight sections covering history, clinical theory, phenomenology, science, aesthetics, religion, ethics, and political and social theory, this Oxford Handbook displays the enduring depth, breadth, and promise of integrating philosophical and psychoanalytic thought. -/- Anyone interested in the philosophical implications of psychoanalysis, as well as philosophical challenges to and re-statements of psychoanalysis, will want to consult this book. It will be a vital resource for academic researchers, psychoanalysts and other mental health professionals, graduates, and trainees. (shrink)

The 1920-1960 period saw the creation of the conditions for a unification of disciplines in the area of evolutionary biology under a limited number of theoretical prescriptions: the evolutionary synthesis. Whereas the sociological dimension of this synthesis was fairly successful, it was surprisingly loose when it came to the interpretation of the evolutionary mechanisms per se, and completely lacking at the level of the foundational epistemological and metaphysical commitments. Key figures such as Huxley, Simpson, Dobzhansky, and Rensch only paid lip (...) service to the conceptual dimension of the evolutionary synthesis, as they eventually realized that a number of evolutionary phenomena could not be explained by its narrow theoretical corpus. Apparently, the evolutionary synthesis constituted a premature event in the development of evolutionary biology. Not only are the real achievements of the evolutionary synthesis in need of reevaluation, but this reassessment also has important implications for the historiography of Darwinism and the current debates about the darwinian movement.

In Mind and World, John McDowell argues against the view that perceptual representation is non-conceptual. The central worry is that this view cannot offer any reasonable account of how perception bears rationally upon belief. I argue that this worry, though sensible, can be met, if we are clear that perceptual representation is, though non-conceptual, still in some sense 'assertoric': Perception, like belief, represents things as being thus and so.

A General treatment of Greek compounds seems much to be desired. It would have to be undertaken by one who had an up-to-date philological equipment, to which I cannot lay claim. But rather with the hope of eliciting discussion on the subject and learning from others I offer the following observations, and in further study of the subject should be grateful to anyone who would advise as to the exact statistics that may be desirable over and above what I give (...) below. I was led to the subject by a feeling that the treatment of many individual compounds by editors was far from satisfactory, and that possibly a collection of the material might help to bring out the exact meaning of some of the well-known difficulties in the Tragedians. One is dealing here with a highly developed and somewhat arbitrary poetic idiom, and it may perhaps be impossible, as one must admit from the outset, always to make precise the poet's meaning, but it is worth while to make the attempt.

A chance-credence norm states how an agent's credences in propositions concerning objective chances ought to relate to her credences in other propositions. The most famous such norm is the Principal Principle (PP), due to David Lewis. However, Lewis noticed that PP is too strong when combined with many accounts of chance that attempt to reduce chance facts to non-modal facts. Those who defend such accounts of chance have offered two alternative chance-credence norms: the first is Hall's and Thau's New Principle (...) (NP); the second is Ismael's General Recipe (IP). Thus, the question arises: Should we adopt NP or IP or both? In this paper, I argue that IP has unacceptable consequences when coupled with reductionism, so we must accept NP alone. (shrink)

Originally published between 1968 and 2009, this collection of 25 pieces includes six interviews translated into English for the first time and a new transcription of a Q&A session with Baudrillard following a lecture he gave in London in 1994. The guiding theme of the collection is Baudrillard's engagement with culture. The implications of the implosion of Western culture are dissected and documented in the rich range of material included here.

In this exciting new collection, a distinguished international group of philosophers contribute new essays on central issues in philosophy of language and logic, in honor of Michael Dummett, one of the most influential philosophers of the late twentieth century. The essays are focused on areas particularly associated with Professor Dummett. Five are contributions to the philosophy of language, addressing in particular the nature of truth and meaning and the relation between language and thought. Two contributors discuss time, in particular the (...) reality of the past. The last four essays focus on Frege and the philosophy of mathematics. The volume represents some of the best work in contemporary analytical philosophy. (shrink)

Hartry Field has suggested that we should adopt at least a methodological deflationism: [W]e should assume full-fledged deflationism as a working hypothesis. That way, if full-fledged deflationism should turn out to be inadequate, we will at least have a clearer sense than we now have of just where it is that inflationist assumptions ... are needed. I argue here that we do not need to be methodological deflationists. More pre-cisely, I argue that we have no need for a disquotational truth-predicate; (...) that the word true, in ordinary language, is not a disquotational truth-predicate; and that it is not at all clear that it is even possible to introduce a disquotational truth-predicate into ordinary language. If so, then we have no clear sense how it is even possible to be a methodological deflationist. My goal here is not to convince a committed deflationist to abandon his or her position. My goal, rather, is to argue, contrary to what many seem to think, that reflection on the apparently trivial character of T-sentences should not incline us to deflationism. (shrink)

Jim Joyce has presented an argument for Probabilism based on considerations of epistemic utility [Joyce, 1998]. In a recent paper, I adapted this argument to give an argument for Probablism and the Principal Principle based on similar considerations [Pettigrew, 2012]. Joyce’s argument assumes that a credence in a true proposition is better the closer it is to maximal credence, whilst a credence in a false proposition is better the closer it is to minimal credence. By contrast, my argument in that (...) paper assumed (roughly) that a credence in a proposition is better the closer it is to the objective chance of that proposition. In this paper, I present an epistemic utility argument for Probabilism and the Principal Principle that retains Joyce’s assumption rather than the alternative I endorsed in the earlier paper. I argue that this results in a superior argument for these norms. (shrink)

Actor‐Network Theory is a research lens that has gained popularity in the nursing and health sciences domains. The perspective allows a researcher to describe the interaction of actors (both human and non‐human) within networked sociomaterial contexts, including complex practice environments where nurses and health technology operate. This study will describe Actor‐Network Theory and provide methodological considerations for researchers who are interested in using this sociotechnical lens within nursing and informatics‐related research. Considerations related to technology conceptualization, levels of analysis, and sampling (...) procedures in Actor‐Network Theory based research are addressed. Finally, implications for future nursing research within complex environments are highlighted. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.3 (2003) 255-259 [Access article in PDF] Illnesses and Likenesses Richard G. T. Gipps IN THIS RESPONSE to Neil Pickering's paper I shall focus only on what he describes as the "strong objection" to the typical use of the likeness argument. The likeness argument, to recap, has it that we can decide whether conditions such as schizophrenia, depression, or alcoholism do or do not (...) deserve the designation of illness depending on whether they possess features which, if they occurred in physical conditions, would enable one to decide for or against the designation. To take an implausible example, if it were decided that it would be enough to describe a physical condition as an illness if it involves pain not caused through injury, then a psychological condition would be appropriately described as an illness just to the extent that it too involved such pain.In arguing against typical deployments of the likeness argument, Pickering finds that it is only on questionable initial descriptions of psychological conditions that such conditions appear to share the features that, in physical conditions, would be taken to be indicative of illness. That is to say, theorists who deploy the likeness argument to urge either the reality or unreality of mental illnesses typically presuppose what both we and they had all along hoped would be demonstrated in their argument. In terms of the above example, we might say that a certain psychological condition can count as an illness if it involves psychic pain. The concept of psychic pain is however (so the argument would have it) contestable; there exist other descriptions that make no reference to pain and in so doing fail to provide what a user of the likeness argument would need to substantiate the claim that a conception of the condition as an illness is more than a façon de parler.By way of arriving at this conclusion the following precondition for the applicability of the likeness argument (Pickering's "assumption" (2)) is insisted on: "That, with respect to the presence or absence of [those features of conditions which features decide whether or not the conditions are illnesses], a condition such as schizophrenia [must be] describable independently of the category it is assigned to." This can seem a quite reasonable restriction, for—it could be said—one can only win an argument if it is first allowed that there is actually something to argue about. That is, it is only if both partisans and detractors of the illness conception first accept a certain description of schizophrenia as spelling out what schizophrenia essentially involves that they can then progress to determining whether or not such a condition so described is or is not an illness.Yet, whereas this seems like a perfectly reasonable requirement, it is I believe uncertain whether it will always capture the form of the intuitions of adherents and detractors of the illness conception—or of the form of philosophical arguments more generally. To be sure, some philosophical discussions can perhaps be reconstructed as debates about the validity of certain inferences [End Page 255] from mutually understood premises (i.e., given X, does Y follow or not?). Yet if this were the case, then genuinely interesting philosophical arguments would probably be few and far between. If we are agreed as to the precise significance of our premises, and are not furthermore just making straightforward mistakes in reasoning, it is hard to see how or why we could all fail to arrive at the same conclusions.In the Philosophical Investigations paragraph 128 Wittgenstein wrote that "If one tried to advance theses in philosophy, it would never be possible to question them, because everyone would agree to them" (Wittgenstein 1953). Now that proposition might seem on rather weak grounds, because all one has to do to actually disprove it is merely disagree with it. But presumably Wittgenstein is rather articulating his intuition that although philosophical arguments often take the form of clashes concerning what conclusions can be drawn from what premises, most of their substance comes from a prior failure to unpack the intrinsic significance...

The Evolutionary Synthesis is often seen as a unification process in evolutionary biology, one which provided this research area with a solid common theoretical foundation. As such, neo-Darwinism is believed to constitute from this time onward a single, coherent, and unified movement offering research guidelines for investigations. While this may be true if evolutionary biology is solely understood as centred around evolutionary mechanisms, an entirely different picture emerges once other aspects of the founding neo-Darwinists’ views are taken into consideration, aspects (...) potentially relevant to the elaboration of an evolutionary worldview: the tree of life, the ontological distinctions of the main cosmic entities , the inherent properties of self-organizing matter, evolutionary ethics, and so on. Profound tensions and inconsistencies are immediately revealed in the neo-Darwinian movement once this broader perspective is adopted. This pluralism is such that it is possible to identify at least three distinct and quasi-incommensurable epistemological/metaphysical frameworks as providing a proper foundation for neo-Darwinism. The analysis of the views of Theodosius Dobzhansky, Bernhard Rensch, and Ernst Mayr will illustrate this untenable pluralism, one which requires us to conceive of the neo-Darwinian research agenda as being conducted in more than one research programme or research tradition at the same time.

Depression and the subjective experience of suffering are distinct forms of distress, but they are sometimes commingled with one another. Using a cross-sectional sample of flight attendants, we tested for further empirical evidence distinguishing depression and suffering. Correlations with 15 indices covering several dimensions of well-being indicated that associations with worse well-being were mostly stronger for depression than suffering. There was a large positive correlation between depression and suffering, but we also found evidence of notable non-concurrent depression and suffering in (...) the sample. After dividing participants into four groups that varied based on severity of depression and suffering, regression analyses showed higher levels of well-being among those with both none-mild depression and none-mild suffering compared to those with moderate-severe depression, moderate-severe suffering, or both. All indices of well-being were lowest among the group of participants with moderate-severe depression and moderate-severe suffering. In addition to providing further evidence supporting a distinction between depression and suffering, our findings suggest that concurrent depression and suffering may be more disruptive to well-being than when either is present alone.

A revelatory alternative to the standard economic models of human behavior that proposes an exciting new way to understand decision-making "Willful is a breakthrough in economics. Richard Robb's tremendously insightful book shows how much of our behavior is not explained by existing theories of human action and explains in sparkling prose why understanding decisions made seemingly without reason presents a fuller picture of our world."--Edmund S. Phelps, Nobel Laureate in Economics Why do we do the things we do? The (...) classical view of economics is that we are rational individuals, making decisions with the intention of maximizing our preferences. Behaviorists, on the other hand, see us as relying on mental shortcuts and conforming to preexisting biases. Richard Robb argues that neither explanation accounts for those things that we do for their own sake, and without understanding these sorts of actions, our picture of decision-making is at best incomplete. Robb explains how these choices made seemingly without reason belong to a realm of behavior he identifies as "for-itself." A provocative combination of philosophy and economics that offers a key to many of our quixotic choices, this groundbreaking volume provides a new way to understand everything from investing to how hard we work to how we manage daily interactions.

In lieu of an abstract, here is a brief excerpt of the content:The Background Theory of Delusion and Existential PhenomenologyRichard G. T. Gipps (bio) and John Rhodes (bio)KeywordsPhenomenology, psychological explanation, epistemology, schizophreniaSituating and Clarifying the PaperThe commentaries of Nassir Ghaemi and Giovanni Stanghellini help to sketch out the intellectual landscape of philosophical perspectives in psychiatry, and situate our paper within it. A happy convergence between the analytical philosophy perspective from which we were writing, and the existential–phenomenological paradigm described by both (...) authors, is the result. Stanghellini in particular carefully describes three main theories of existential deformations, tracing delusion formation back to either (i) a disturbance of meaning synthesis conceived as a dysfunction of a Husserlian consciousness, (ii) a disturbance of pre-reflective self-consciousness resulting in a kind of paralyzing hyperreflexivity, and (iii) (Stanghellini’s preferred model) a disturbance of embodiment. This final account views delusion as springing from a failure in the subject’s corporeal and praxical being-in-the-world. As the subject’s practical, pre-reflective grip on the world is loosened, so their minds become unconstrained by that understanding and practical rationality immanent within that grip, and thought, now unconstrained, starts to travel through delusional worlds. Stanghellini accordingly views our model as an example of a disembodiment theory, which allows it to overcome the disadvantages of the first two models, which may both, in their own ways, overvalue the rôle of (disturbances of) reflective consciousness in the formation (and delusional deformation) of everyday understanding.Being situated within a preexisting landscape has both its benefits and its disbenefits, the principle example of the latter being the potential assimilation of anything new to what has already been said. Thus, although we are grateful to our commentators for placing us on the larger historical and conceptual map, it may be helpful to briefly rehearse our motivations for drawing on the philosophical ideas of the Bedrock and Background in our theory of delusion. Our paper was primarily motivated by a concern that current, psychologically mainstream, cognitive models of delusion, although helpfully drawing our attention to common reasoning and perceptual deficits in the person with psychosis, fail to adequately account for what is delusional about delusions. It was, in [End Page 321] particular, to account for the certainty with which the deluded person clings to often quite extraordinary beliefs that we drew on the epistemological notion of the background. And although this epistemological notion fits quite neatly with ontological concerns regarding the embodied and praxical character of human existence, it is the particular epistemic rôle that it played in our theory—to do with the extraratiocinative constraint on judgement provided by the Background—that we wish to stress here.We return to this shortly, but first wish to comment briefly on two specific considerations raised by the commentaries. The first concerns Stanghellini’s claim that, for us, “when studying delusions, the focus should be on providing an adequate framework for understanding, rather than providing empirical hypotheses to be tested” (2008, 311–314). It seems to us, however, that both are equally important. What we wished to stress, however, was that empirical hypothesis testing may be led astray if it is not informed by an adequate framework for understanding. For example, most cognitive psychological experiments on delusions concern themselves with the individual’s ability to make appropriate guesses (e.g., regarding the color of beads in a bag), and their tendency to jump to conclusions; they do not concern themselves with the kinds of extraordinary conviction and certainty met with in delusion. The risk run by empirical researchers of cognitive factors in delusion is that a lack of a prior adequate theorization of delusion makes for accounts that are ultimately only of the formation, not of delusion in particular but rather of false or unusual beliefs more generally. An analytical approach, however, can help to explicate the ways in which the psychiatric concept of delusion fails to be adequately characterized by the quite general ‘external criteria’ of delusion (as Jaspers [1963] called them: falsity, stubbornness, uncommon), and aids in the construction of empirical hypotheses this time constrained by an understanding of the true ‘internal criteria’ of psychotic belief. Such an approach helps to spell out the... (shrink)

This book offers a thorough reanalysis of Charles Darwin's Origin of Species, which for many people represents the work that alone gave rise to evolutionism. Of course, scholars today know better than that. Yet, few resist the temptation of turning to the Origin in order to support it or reject it in light of their own work. Apparently, Darwin fills the mythical role of a founding figure that must either be invoked or repudiated. The book is an invitation to move (...) beyond what is currently expected of Darwin's magnum opus. Once the rhetorical varnish of Darwin's discourses is removed, one discovers a work of remarkably indecisive conclusions. The book comprises two main theses: The Origin of Species never remotely achieved the theoretical unity to which it is often credited. Rather, Darwin was overwhelmed by a host of phenomena that could not fit into his narrow conceptual framework. In the Origin of Species, Darwin failed at completing the full conversion to evolutionism. Carrying many ill-designed intellectual tools of the 17th and 18th centuries, Darwin merely promoted a special brand of evolutionism, one that prevented him from taking the decisive steps toward an open and modern evolutionism. It makes an interesting read for biologists, historians and philosophers alike. (shrink)

Talk of matters ethical is, in the psychotherapeutic context, typically relegated to therapy’s preconditions and setting, i.e., to its ‘frame’. What goes on within that frame, i.e., therapeutic action itself, gets theorised in psychological rather than ethical terms. An explanation for this is the frequent therapeutic imperative to extirpate self-directed moralising. Moralising, however, constitutes but a phoney pretender to the ethical life. A true ethical sensibility instead shows itself in such moments of life as involve our offering humane recognition to (...) one another and to ourselves. Being offered such recognition not only allows a patient to internalise it as a remoralising dignity or healthy pride. It also enables the patient to know herself by animating within herself a range of virtue concepts—courage, probity, repentance, etc.—which can then function as regulative ideals for a well-functioning psyche. Inchoate anxiety now takes shape as intelligible guilt. Repentance and the repair of damaged relationships now replace blame’s repression or projection. Conscience now becomes a motor for therapeutic change. In such ways, ethical concern constitutes not merely the frame but the living flesh of the therapeutic project. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Madness, Reason, and PrideRichard G.T. Gipps, PhD (bio)MadnessQuestions such as “what’s madness?” or “what’s reason?” carry no singular sense about with them wherever they go—which isn’t to say that, asked out of a particular interest in a particular context, they can’t be perfectly intelligible. Garson (2023) is wise to this when he follows “what is madness?” with “as opposed to what?”, even if this latter question itself hardly enjoys (...) a clear sense in the initial context of his asking. What counts as a satisfactory answer to “what’s x?” varies, so that sometimes we’ll be satisfied with a name, at other times by information about something’s genus, origin, function, or composition. Things get notoriously tricky when in the philosophical context the question is asked with a presumption of intelligibility despite ‘x’ being, say, an abstract noun formed from an adjective (‘consciousness’ out of ‘conscious’; ‘happiness’ out of ‘happy’; ‘madness’ out of ‘mad,’ etc.). For “what is?” questions are typically most perspicuously mooted when what’s being pursued are enquiries into (what we might call) the ‘essential nature’ of (what philosophers used to call) ‘substances’ or (of what are more ordinarily called) types of ‘thing’ or ‘entity.’ Invoke, by taking one’s lead from the fact that an ‘x’ is grammatically speaking a substantive, the specter of substance, and you can endlessly baffle yourself by now pondering the mysteries of the putative thing. (Vide discussions of “the nature of consciousness.”) Hence the boon of instead pursuing questions of an ‘opposed to what?’ sort; hence Wittgenstein considering using the Earl of Kent’s “I’ll teach you differences” (King Lear) as a motto for his Investigations. Rather more reflective wisdom regarding ‘x’ may thus be gained when we learn to contrast it with ‘y’ and ‘z’ than when peering into x’s non-existent constitution or groping for its never-instituted genus.Later, I make the case that Garson’s conception of reason itself might suffer from a form of substantialization and that, if I’m right in this, troubling implications follow for his approach to madness. But let’s begin by considering his enquiry into the relation of madness, idiocy and reason. So perhaps we’re reflecting on matters legal, and considering—since we’d hitherto been inclined to take ‘reason’ as univocal—what justifies our different treatments of the insane, the intellectually subnormal, and the normal. Or perhaps—proceeding from the same inclination—we’re puzzled by how someone may boast an exceptional IQ or demonstrate marvelous formal rationality (i.e., make deductions of a sort which would please the logician if no-one else) and yet still be quite mad. And then we realize that at which Garson’s Late Moderns seem to have been gesturing: The lack of reason qua intelligence in idiocy is a different [End Page 307] species from the lack of reason qua sanity in madness. An amethyst is lifeless in a different manner than an expired possum (it was never living, never moribund); the arational lack reason in a different sense than do the irrational (and a baobab cannot jump to conclusions.) There is, say his Late Modern theorists, something ‘perverse’ rather than simply deficient about the irrationality of madness.Now an important part of Garson’s thesis has it that “idiocy is a better candidate for the opposite of reason than madness.” One of the reasons for his making this claim is that he follows his Late Moderns in claiming that madness has reason somehow alive within it, albeit in an unconventional or surprising form. I return to his own explication of this below. Consider first, though, the different thought-referencing descriptions under which the speech acts of the thought-disordered, the speech-disordered, the delusional, and the learning disabled subject may be brought. The sufferer of speech disorder has difficulty with fluency or sound production, but once we get used to this we can find our way to the bona fide rational thought immanent within their discourse. The speech acts of the intellectually impaired subject aren’t chaotic, but instead want for invention and richness; they fail to express... (shrink)
