Contrary to common misconceptions, today's logic is not devoid of existential import: the universalized conditional ∀ x [S→ P] implies its corresponding existentialized conjunction ∃ x [S & P], not in all cases, but in some. We characterize the proexamples by proving the Existential-Import Equivalence: The antecedent S of the universalized conditional alone determines whether the universalized conditional has existential import, i.e. whether it implies its corresponding existentialized conjunction.A predicate is an open formula having only x free. An existential-import predicate (...) Q is one whose existentialization, ∃ x Q, is logically true; otherwise, Q is existential-import-free or simply import-free.How abundant or widespread is existential import? How abundant or widespread are existential-import predicates in themselves or in comparison to import-free predicates? We show that existential-import predicates are quite abundant, and no less so than import-free predicates. Existential.. (shrink)

This paper focuses on Nietzsche’s claim that suffering is closely related to the realization of certain perfectionist values, such as artistic excellence. According to Bernard Reginster, creative achievement consists in overcoming suffering, and therefore, suffering is an essential ingredient of creative achievement. Because suffering forms an essential part of a valuable whole in this way, Reginster argues that we must in turn value suffering ‘for its own sake’. This paper argues that Reginster’s position is open to the following objection: from (...) the fact that suffering is an essential part of a valuable whole, it does not follow that suffering is itself valuable. Rather, by taking advantage of the principle of organic unities, it would have to form an essential part of a valuable whole in a particular way. The author considers two ways the principle might be attributed to Nietzsche’s views on suffering: first, as an ‘enabling condition’, in which suffering allows for a whole that outweighs its disvalue; and second, as ‘a contributor’, in which suffering positively contributes value to the whole. The paper explores how Nietzsche’s ethics turns out to be crucially informed by this conceptual distinction. (shrink)

ABSTRACT The aim of this paper is to elucidate Schopenhauer’s moral philosophy in terms of an ethics of virtue. This paper consists of four sections. In the first section I outline three major objections Schopenhauer raises for Kant’s moral philosophy. In section two I extract from these criticisms a framework for Schopenhauer’s own position, identifying how his moral psychology underpins a unified and hierarchical conception of virtue and vice. I then ascertain some strengths of this view. In section three I (...) focus in upon the issue of fixed character and moral education as at least one major point of divergence between Schopenhauer’s virtue ethics and typical trends within the tradition. In the fourth and final section, I consider and respond to this ethical framework’s possible susceptibility to the charge of egoism, and adjudicate among competing solutions in the secondary literature. I conclude that refined forms of Schopenhauer’s ethical views offer rich and plausible insights into both virtue and vice which have received less attention than they deserve. Hence, Schopenhauer warrants more serious concern in contemporary discussions of virtue ethics alongside the likes of Aristotle, Hume and Nietzsche. (shrink)

The point of this paper is to reveal a dogma in the ordinary conception of sensory imagination, and to suggest another way forward. The dogma springs from two main sources: a too close comparison of mental imagery to perceptual experience, and a too strong division between mental imagery and the traditional propositional attitudes (such as belief and desire). The result is an unworkable conception of the correctness conditions of sensory imaginings—one lacking any link between the conditions under which an imagining (...) aids human action and inference and the conditions under which it is veridical. The proposed solution is, first, to posit a variety of imaginative attitudes—akin to the traditional propositional attitudes—which have different associated correctness (or satisfaction) conditions. The second part of the solution is to allow for imaginings with “hybrid” contents, in the sense that both mental images and representations with language-like constituent structure contribute to the content of imaginings.

​Imagination will remain a mystery—we will not be able to explain imagination—until we can break it into parts we already understand. Explaining Imagination is a guidebook for doing just that, where the parts are other ordinary mental states like beliefs, desires, judgments, and decisions. In different combinations and contexts, these states constitute cases of imagining. This reductive approach to imagination is at direct odds with the current orthodoxy, according to which imagination is a sui generis mental state or process—one with (...) its own inscrutable principles of operation. Explaining Imagination upends that view, showing how, on closer inspection, the imaginings at work in hypothetical reasoning, pretense, the enjoyment of fiction, and creativity are reducible to other familiar mental states—judgments, beliefs, desires, and decisions among them. Crisscrossing contemporary philosophy of mind, cognitive science, and aesthetics, Explaining Imagination argues that a clearer understanding of imagination is already well within reach. (shrink)

One feature of the individuals Nietzsche considers paradigms of greatness is that they are, in some capacity, rare —an exception to the majority.1 It would be difficult to overstate the frequency of this association in the texts. From as early as UM, Nietzsche repeatedly contrasts the “rarest and most valuable exemplars” with the pejorative “herd [Heerde]”, the “common [gemein]”, the “mediocre [mittelmässig]”, and the “rabble [Pöbel]”.2 This contrast becomes more explicit in Nietzsche’s mature period, where, for example, he writes plainly (...) that “what can be common has ever but little...

Smith has argued that moral realism need not be threatened by apparent moral disagreement. One reason he gives is that moral debate has tended to elicit convergence in moral views. From here, he argues inductively that current disagreements will likely be resolved on the condition that each party is rational and fully informed. The best explanation for this phenomenon, Smith argues, is that there are mind-independent moral facts that humans are capable of knowing. In this paper, I seek to challenge (...) this argument—and more recent versions of it—by arguing that historical convergence in moral views may occur for various arational reasons. If such reasons possibly result in convergence—which Smith effectively concedes—then the moral realist would require an additional a posteriori argument to establish that convergence in moral views occurred for the right reasons. Hence, Smith-style arguments, as they stand, cannot be mobilised in support of moral realism. Rather, this investigation demonstrates the necessity of a genuine history of morality for any convergence claim in support of a meta-ethical view. (shrink)

Martin and Deutscher’s causal theory of remembering holds that a memory trace serves as a necessary causal link between any genuine episode of remembering and the event it enables one to recall. In recent years, the causal theory has come under fire from researchers across philosophy and cognitive science, who argue that results from the scientific study of memory are incompatible with the kinds of memory traces that Martin and Deutscher hold essential to remembering. Of special note, these critics observe, (...) is that a single memory trace can be shaped by multiple past experiences. This appears to prevent traces from underwriting Martin and Deutscher’s distinction between remembering an event and merely forming an accurate representation of it. This paper accepts such criticisms of the standard causal theory and, through considering the phenomenon forgetting through repetition, raises several others. A substantially revised causal theory is then developed, compatible with the thesis that individual memory traces are shaped by multiple past experiences. The key strategy is to conceive of episodic remembering not as the simple retrieval and projection of a static memory trace, but as a complex quasi-inferential process that makes use of multiple forms of information and cues—“prop-like” memory traces included—in generating the experience known as episodic remembering. When remembering is understood as a multi-componential process, there are a variety of ways in which a representation of the past may be appropriately causally dependent upon a prior experience of the event remembered.

The current ethical norms of genomic biobanking creating and maintaining large repositories of human DNA and/or associated data for biomedical research have generated criticism from every angle, at both the practical and theoretical levels. The traditional research model has involved investigators seeking biospecimens for specific purposes that they can describe and disclose to prospective subjects, from whom they can then seek informed consent. In the case of many biobanks, however, the institution that collects and maintains the biospecimens may not itself (...) be directly involved in research, instead banking the biospecimens and associated data for other researchers. Moreover, the future uses of biospecimens may be unknown, if not unknowable, at the time of collection. Biobanking may thus stretch the meanings of inform and consent to their breaking point: if you cannot inform subjects about what their biospecimens will be used for, what can they consent to? Given that informed consent by individual subjects is the ethical gold standard, the seeming dilution of the concept in the context of biobanking is a profound problem. (shrink)

The (dis)continuism debate in the philosophy and cognitive science of memory concerns whether remembering is continuous with episodic future thought and episodic counterfactual thought in being a form of constructive imagining. I argue that settling that dispute will hinge on whether the memory traces (or “engrams”) that support remembering impose arational, perception-like constraints that are too strong for remembering to constitute a kind of constructive imagining. In exploring that question, I articulate two conceptions of memory traces—the replay theory and the (...) prop theory—that return conflicting answers to whether remembering is constructive imagining. The prop theory’s vision of traces is suggestive of continuism, while the replay theory’s is a natural fit for discontinuism. Which view of traces is in fact correct remains undetermined by current empirical work. Nevertheless, it may already be possible to reach a compromise in the (dis)continuism debate, through the development of a conciliatory continuist causal theory. This view—only outlined here—accepts the continuism-friendly prop theory of traces, while still requiring that genuine remembering fulfills an appropriate causation condition, as required by the kinds of causal theories of remembering typically favored by discontinuists.

If imagination is subject to the will, in the sense that people choose the content of their own imaginings, how is it that one nevertheless can learn from what one imagines? This chapter argues for a way forward in addressing this perennial puzzle, both with respect to propositional imagination and sensory imagination. Making progress requires looking carefully at the interplay between one’s intentions and various kinds of constraints that may be operative in the generation of imaginings. Lessons are drawn from (...) the existing literature on propositional imagination and from the control theory literature concerning the prediction and comparison mechanisms (or “forward models”) involved in ordinary perception. A more general conclusion is reached that, once we have the tools to understand how some imaginings are both under willful control and helpfully guide action and inference, we will have what we need to understand the cognitive basis of imagination in general.

It is often observed that images—including mental images—are in some sense representationally ambiguous. Some, including Jerry Fodor, have added that mental images only come to have determinate contents through the contribution of non-imagistic representations that accompany them. This paper agrees that a kind of ambiguity holds with respect to mental imagery, while arguing (pace Fodor) that this does not prevent imagery from having determinate contents in the absence of other, non-imagistic representations. Specifically, I argue that mental images can represent determinate (...) types of outlays of properties without help from any non-imagistic representations, yet can only become involved in the representation of particular objects through pairing with a non-imagistic representation of the right sort. These points are defended through reflection on the “Picture Principle,” the nature of depiction, and general principles for typing and individuating mental states. (shrink)

A popular view has it that the mental representations underlying human pretense are not beliefs, but are “belief-like” in important ways. This view typically posits a distinctive cognitive attitude (a “DCA”) called “imagination” that is taken toward the propositions entertained during pretense, along with correspondingly distinct elements of cognitive architecture. This paper argues that the characteristics of pretense motivating such views of imagination can be explained without positing a DCA, or other cognitive architectural features beyond those regulating normal belief and (...) desire. On the present “Single Attitude” account of imagination, propositional imagining just is a form of believing. The Single Attitude account is also distinguished from “metarepresentational” accounts of pretense, which hold that both pretending and recognizing pretense in others require one to have concepts of mental states. It is argued, to the contrary, that pretending and recognizing pretense require neither a DCA nor possession of mental state concepts. (shrink)

This essay unites current philosophical thinking on imagination with a burgeoning debate in the philosophy of memory over whether episodic remembering is simply a kind of imagining. So far, this debate has been hampered by a lack of clarity in the notion of imagining at issue. Several options are considered and constructive imagining is identified as the relevant kind. Next, a functionalist account of episodic remembering is defended as a means to establishing two key points: first, one need not defend (...) a factive view of remembering in order to hold that causal connections to past experiences are essential to how rememberings are typed; and, second, current theories that equate remembering with imagining are in fact consistent with a functionalist theory that includes causal connections in its account of what it is to remember. This suggests that remembering is not a kind of imagining and clarifies what it would take to establish the contrary. (shrink)

Currie’s (2010) argument that “i-desires” must be posited to explain our responses to fiction is critically discussed. It is argued that beliefs and desires featuring ‘in the fiction’ operators—and not sui generis imaginings (or "i-beliefs" or "i-desires")—are the crucial states involved in generating fiction-directed affect. A defense of the “Operator Claim” is mounted, according to which ‘in the fiction’ operators would be also be required within fiction-directed sui generis imaginings (or "i-beliefs" and "i-desires"), were there such. Once we appreciate that (...) even fiction-directed sui generis imaginings would need to incorporate ‘in the fiction’ operators, the main appeal of the idea that sui generis imaginings (or "i-beliefs" or "i-desires") are at work in fiction-appreciation dissipates.

Much of what we say is never said aloud. It occurs only silently, as inner speech. We chastise, congratulate, joke and cajole, all without making a sound. This distinctively human ability to create public language in the privacy of our own minds is no less remarkable for its familiarity. And yet, until recently, inner speech remained at the periphery of philosophical and psychological theorizing. This essay collection, from an interdisciplinary group of leading philosophers, psychologists, and neuroscientists, displays the rapidly growing (...) interest among researchers in the puzzles surrounding the nature and cognitive role of the inner voice. Questions explored include: the aids and obstacles inner speech presents to self-knowledge; the complex relation it bears to overt speech production and perception; the means by which inner speech can be identified and empirically assessed; its role in generating auditory verbal hallucinations; and its relationship to conceptual thought itself.

This study draws on neo-institutional theory to examine how and why corporate environmental management practices might affect environmental performance. It contributes to the literature by using a large, global data set to investigate the impact of 10 corporate environmental management practices on greenhouse gas emissions or emissions intensity.

Our (...) results are based on a dynamic, robust and large-scale econometric analysis, which includes tests of association and Granger causation in comparison with earlier research. A key finding, which is of interest not only to the academic literature but also to policymakers and managers, is that environmental performance impacts environmental management practices but not vice versa, supporting the hypothesis that corporations adopt these practices as a symbolic legitimizing device rather than a genuine attempt derived from moral obligation to reduce their greenhouse gases or carbon intensity.

Inner speech travels under many aliases: the inner voice, verbal thought, thinking in words, internal verbalization, “talking in your head,” the “little voice in the head,” and so on. It is both a familiar element of first-person experience and a psychological phenomenon whose complex cognitive components and distributed neural bases are increasingly well understood. There is evidence that inner speech plays a variety of cognitive roles, from enabling abstract thought, to supporting metacognition, memory, and executive function. One active area of (...) controversy concerns the relation of inner speech to auditory verbal hallucinations in schizophrenia, with a common proposal being that sufferers of AVH misidentify their own inner speech as being generated by someone else. Recently, researchers have used artificial intelligence to translate the neural and neuromuscular signatures of inner speech into corresponding outer speech signals, laying the groundwork for a variety of new applications and interventions.

Cats and dogs are the same kind of thing in being mammals, even if cats are not a kind of dog. In the same way, remembering and imagining might be the same kind of mental state, even if remembering is not a kind of imagining. This chapter explores whether episodic remembering, on the one hand, and future and counter-factual directed imagistic imagining, on the other, may be the same kind of mental state in being instances of the same cognitive attitude. (...) I outline a continuist position where all three involve the same judgment-like attitude and compare its advantages to a discontinuist alternative where remembering requires use of its own distinctive attitude. Reasons are given for favoring a version of the continuist position, though this chapter’s focus is on the metatheoretical questions of how to go about understanding remembering in terms of a content and attitude pair, and which considerations are relevant when deciding among competing content/attitude pairs.

Whether a person is pretending, or not, is a function of their beliefs and intentions. This poses a challenge to 4E accounts of pretense, which typically seek to exclude such cognitive states from their explanations of psychological phenomena. Resulting tensions are explored within three recent accounts of imagination and pretense offered by theorists working in the 4E tradition. A path forward is then charted, through considering ways in which explanations can invoke beliefs and intentions while remaining true to 4E precepts. (...) To make real progress in explaining pretense, 4E theorists will need to grow comfortable with the idea that two agents whose outward behaviors and environments are, in the short term, the same, may be guided by quite different beliefs and intentions, in virtue of which only one is pretending. In this way, the scientific project of explaining pretense remains inseparable from the more general project of determining which beliefs and intentions are appropriate to ascribe to which kinds of entities, given which kinds of behaviors.

Many theorists claim that inner speech is importantly linked to human metacognition (thinking about one's own thinking). However, their proposals all rely upon unworkable conceptions of the content and structure of inner speech episodes. The core problem is that they require inner speech episodes to have both auditory-phonological contents and propositional/semantic content. Difficulties for the views emerge when we look closely at how such contents might be integrated into one or more states or processes. The result is that, if inner (...) speech is especially valuable to metacognition, we do not currently understand why it is. The article concludes with two positive proposals for understanding the content and structure of inner speech episodes, which should serve as constraints on future accounts of the metacognitive value of inner speech.

Abstract: How it is that one's own thoughts can seem to be someone else's? After noting some common missteps of other approaches to this puzzle, I develop a novel cognitive solution, drawing on and critiquing theories that understand inserted thoughts and auditory verbal hallucinations in schizophrenia as stemming from mismatches between predicted and actual sensory feedback. Considerable attention is paid to forging links between the first-person phenomenology of thought insertion and the posits (e.g. efference copy, corollary discharge) of current cognitive (...) theories. I show how deficits in the subconscious mechanisms regulating inner speech may lead to a 'fractured phenomenology' responsible for schizophrenic patients' reports of inserted thoughts and auditory verbal hallucinations. Supporting work on virtual environments is discussed, and lessons concerning the fixity of delusional belief are drawn. (shrink)

Pretense is a topic of keen interest to philosophers and psychologists. But what is it, really, to pretend? What features qualify an act as pretense? Surprisingly little has been said on this foundational question. Here I defend an account of what it is to pretend, distinguishing pretense from a variety of related but distinct phenomena, such as (mere) copying and practicing. I show how we can distinguish pretense from sincerity by sole appeal to a person's beliefs, desires, and intentions – (...) and without circular recourse to an ‘intention to pretend’ or to a sui generis mental state of ‘imagining.’.

If we are free to imagine what we choose, this is likely because our intentions determine what we are imagining. However, in a recent article, Munro and Strohminger (2021) argue that, in some cases of imagistic imagining, our intentions do not determine what we are imagining. They offer examples where, intuitively, a person intends to imagine one thing but, due to the causal source of the image used, imagine another. This paper acknowledges the challenge posed by these cases while arguing (...) on several grounds that, when present, intentions nevertheless always suffice to determine the object of one’s imaginings. I conclude by explaining how intentions could fix the objects of episodic rememberings in much the same way as they do for imaginings, thereby bolstering the case that remembering is a kind of imagining.

In recent years, language has been shown to play a number of important cognitive roles over and above the communication of thoughts. One hypothesis gaining support is that language facilitates thought about abstract categories, such as democracy or prediction. To test this proposal, a novel set of semantic memory task trials, designed for assessing abstract thought non-linguistically, were normed for levels of abstractness. The trials were rated as more or less abstract to the degree that answering them required the participant (...) to abstract away from both perceptual features and common setting associations corresponding to the target image. The normed materials were then used with a population of people with aphasia to assess the relationship of abstract thought to language. While the language-impaired group with aphasia showed lower overall accuracy and longer response times than controls in general, of special note is that their response times were significantly longer as a function of a trial’s degree of abstractness. Further, the aphasia group’s response times in reporting their degree of confidence (a separate, metacognitive measure) were negatively correlated with their language production abilities, with lower language scores predicting longer metacognitive response times. These results provide some support for the hypothesis that language is an important aid to abstract thought and to metacognition about abstract thought. (shrink)

Comparatively easy questions we might ask about creativity are distinguished from the hard question of explaining transformative creativity. Many have focused on the easy questions, offering no reason to think that the imagining relied upon in creative cognition cannot be reduced to more basic folk psychological states. The relevance of associative thought processes to songwriting is then explored as a means for understanding the nature of transformative creativity. Productive artificial neural networks—known as generative antagonistic networks (GANs)—are a recent example of (...) how a system’s ability to generate novel products can both be finely tuned by prior experience and grounded in strategies that cannot be articulated by the system itself. Further, the kinds of processes exploited by GANs need not be seen as incorporating something akin to sui generis imaginative states. The chapter concludes with reflection on the added relevance of personal character to explanations of creativity. [This is Chapter 12 of the book Explaining Imagination.]. (shrink)

Despite the ubiquity of inner speech in our mental lives, methods for objectively assessing inner speech capacities remain underdeveloped. The most common means of assessing inner speech is to present participants with tasks requiring them to silently judge whether two words rhyme. We developed a version of this task to assess the inner speech of a population of patients with aphasia and corresponding language production deficits. As expected, patients’ performance on the silent rhyming task was severely impaired relative to controls. (...) More surprisingly, however, patients’ performance on this task did not correlate with their performance on a variety of other standard tests of overt language abilities. In particular, patients who were generally unimpaired in their abilities to overtly name objects during confrontation naming tasks, and who could reliably judge when two words spoken to them rhymed, were still severely impaired (relative to controls) at completing the silent rhyme task. This seems to suggest that inner speech was more severely impaired in these patients than outer speech. However, these results should also cause us to critically reflect on the relation between inner speech and silent rhyme judgments more generally. (shrink)

Pervasive digitality reveals us as analogue creatures that are unprepared for a world and a logic generated increasingly through automation. Promulgated by capitalism, digitality has created a new form of alienation, one far more powerful and comprehensive than that envisaged by either Marx or Lukács in the analogue-industrial age. Digital alienation-through-automation is the central process in our digital post-modernity. The effects reach increasing registers and spheres of culture, economy and politics. This essay considers the effects within the production of knowledge (...) within higher education. Through a critique of Clayton Christensen’s concept of ‘disruptive technologies’, it develops the argument that knowledge produced in our higher institutions of learning suffer from two forms of ‘knowledge capture’. The first and most comprehensive is knowledge increasingly oriented toward instrumental outcomes, generated in vocationally oriented and market-pressured contexts, and produced by the general-sector institutions; second is knowledge, much of it profound and potentially world-changing—in economics and climate science in the cases discussed here. These are generated in both prestigious general-sector universities, and in the elite Ivy League and Russell Group universities but are unable to gain traction with an ascendant and alien post-Westphalian, post-modern and post-Enlightenment political context—created by a globalising digitality. I argue that unless we recognise our analogue essence, and that this has been alienated by digital automation, then the aporias of digitality, with knowledge production an important element, then our institution of higher learning will continue to produce much valuable knowledge that has diminishing practical (political) effect.

This paper examines the history of glass colouring. It reviews Kitāb al-Durra al-maknūna of Jābir ibn Ḥayyān, which deals with the subject. The manuscript of this practical treatise was discovered recently. Part one of the paper deals with Jābir as a philosopher and chemist. The art of lustre-painting on glass originated in Syria during the Umayyad Caliphate in the eighth century and was soon practised in the neighbouring area. The paper reviews Arabic literature that deals with the colouring of glass (...) until the 13th century, and with pre-Islamic and Latin books of recipes that deal with glass colouring. Recipes for cast coloured glass are very few and scant in non-Arabic literature, and lustre-painting on glass was not mentioned in any treatise outside Arabic, even in the works of Theophilus and Neri. The colouring of glass gemstones by colour diffusion is not mentioned also. The paper compares the recipes of Kitāb al-Durra with the results of modern analysis of existing Islamic stained glass objects. There is a close correspondence, and the main indispensable ingredients in both cases are silver and copper compounds. Part one ends with an account of lāzaward as cobalt oxide in glass colouring. Part two of the paper gives a representative selection of recipes from Kitāb al-Durra for the three methods of glass colouring. (shrink)

It is widely held that introspection-based self-ascriptions of mental states are immune to error through misidentification , relative to the first person pronoun. Many have taken such errors to be logically impossible, arguing that the immunity holds as an “absolute” necessity. Here I discuss an actual case of craniopagus twins—twins conjoined at the head and brain—as a means to arguing that such errors are logically possible and, for all we know, nomologically possible. An important feature of the example is that (...) it is one where a person may be said to be introspectively aware of a mental state that occurs outside of her own mind. Implications are discussed for views of the relation between introspection and mental state ownership, and between introspection and epistemic criteria for the “mark of the mental.”. (shrink)

In reply to Daniel Hutto’s “Getting Real About Pretense,“ I defend my theory of pretense against his claim that it is subject to counterexamples by clarifying wherein the value of the analysis lies. Then I argue that the central challenge still facing Hutto’s “primacy of practice” approach, as well as other 4E approaches to pretense, is to explain the link between pretense and deception.

Many philosophers and psychologists have sought to explain experiences of auditory verbal hallucinations and “inserted thoughts” in schizophrenia in terms of a failure on the part of patients to appropriately monitor their own inner speech. These self-monitoring accounts have recently been challenged by some who argue that AVHs are better explained in terms of the spontaneous activation of auditory-verbal representations. This paper defends two kinds of self-monitoring approach against the spontaneous activation account. The defense requires first making some important clarifications (...) concerning what is at issue in the dispute between the two forms of theory. A popular but problematic self-monitoring theory is then contrasted with two more plausible conceptions of what the relevant self-monitoring deficits involve. The first appeals to deficits in the neural mechanisms that normally filter or attenuate sensory signals that are the result of one’s own actions. The second, less familiar, form of self-monitoring approach draws an important analogy between Wernicke’s aphasia and AVHs in schizophrenia. This style of self-monitoring theory pursues possible connections among AVHs, inserted thoughts, and the disorganized speech characteristic formal thought disorder. (shrink)

The Arabic-Islamic tradition is founded on the following new epistemic attitude that reinvents knowledge: to learn from the contributions of previous civilisations through the systematic survey of all extant scientific works; to contribute to the further development of knowledge by linking it, through usefulness, to practice and the practical need of society; to facilitate its learning for younger generations and its transmission to future civilizations since it is conceived not as a finished product but as an ongoing process.

It is often held that in imagining experiences we exploit a special imagistic way of representing mentality—one that enables us to think about mental states in terms of what it is like to have them. According to some, when this way of thinking about the mind is paired with more objective means, an explanatory gap between the phenomenal and physical features of mental states arises. This paper advances a view along those lines, but with a twist. What many take for (...) a special imagistic way of thinking about experiences is instead a special way of misconstruing them. It is this tendency to misrepresent experiences through the use of imagery that gives rise to the appearance of an explanatory gap. The pervasiveness and tenacity of this misrepresentational reflex can be traced to its roots in a particular heuristic for monitoring and remembering the mental states of others. The arguments together amount to a new path for defending the transparency of perceptual experience. (shrink)
