This paper presents an approach to artificial intelligence planning based on linear temporal logic (LTL). A simple and easy-to-use planning language is described, Planning Domain Description Language with control Knowledge (PDDL-K), which allows one to specify a planning problem together with heuristic information that can be of help for both pruning the search space and finding better quality plans. The semantics of the language is given in terms of a translation into a set of LTL formulae. Planning (...) is then reduced to “executing” the LTL encoding, i.e. to model search in LTL. The feasibility of the approach has been successfully tested by means of the system Pdk, an implementation of the proposed method. (shrink)

Mirror systems must be supplemented by a planning capability to allow language to evolve. A capability for creating, storing, and executing plans for sequences of actions, having evolved in primates, was applied to sequences of communicatory acts. Language could exploit this already-existing capability. Further steps in language evolution may parallel steps seen in the development of modern children.

This paper is concerned with those elements of planning knowledge that are common to both understanding someone else's plan and creating a plan for one's own use. This planning knowledge can be divided into two bodies: Knowledge about the world, and knowledge about the planning process itself. Our interest here is primarily with the latter corpus. The central thesis is that much of the knowledge about the planning process itself can be formulated in terms of higher‐level goals and plans called (...) meta‐goals and meta‐plans. These entities can then be used by the same understanding and planning mechanisms that process ordinary goals and plans. However, the meta‐planning knowledge now enables these mechanisms to handle much more complicated situations in a uniform manner.Systems based on meta‐planning would have a number of advantages over existing problem solving and understanding systems. The same knowledge could be shared by both a planner and understander, and both would be able to handle complex situations elegantly. In addition, in planning, the use of meta‐planning has several advantages over more traditional methods involving constraints or critics. Meta‐planning allows the full power of a problem solver to be applied to situations that are generally amenable only to special purpose processing. In addition, meta‐planning facilitates the representation of some situations that are difficult to express otherwise. We have begun to introduce meta‐planning knowledge into two systems: PAM, a story understanding program, and PANDORA, a problem solving and plannin̈g system. (shrink)

In this article we propose that executive functions play a key role in the origin of language. Our proposal is based on the methodological assumption that some of the cognitive systems involved in language functioning are also involved in its phylogenetic origin. In this regard, we demonstrate that a key property of language functioning is discourse coherence. Such property is not dependent on grammatical elements but rather is processed by cognitive systems that are not specific for (...) class='Hi'>language, namely the executive functions systems of action planning, control and organization. Data from cognitive archaeology on the making of stone tools show that the processes requested to produce Prehistoric tools imply action organization operations similar to those involved in the processing of coherence. Based on these considerations, we propose that executive functions represent the link between stone tool making and language origins and suggest that they allowed our ancestors to develop forms of proto-discourse governed by coherence.

The human person has been analyzed from several points of view throughout the history. Great theologians, philosophers, anthropologists and sociologists and other specialists have written extensively on the subject. The philosophical contribution centered on the human person has been significant throughout history. In the last century, Romano Guardini, who received the Erasmus Prize for Best European Humanist and called "Master of Life" offers a view of reality man-centered, through a thin, deep and coherent approach on the individual. His work has (...) been labeled by some philosophers within the personalist current, and although his contributions were many, we want to highlight the elements of the meeting, the language and the self-acceptance. In this paper we propose how this approach to the human person can become an intinerary embodied in reality, that can help today to seek clarification and start delving into own personal knowledge enlightened by faith. -/- La persona humana ha sido analizada desde varios puntos de vista a lo largo de la historia.

There is much in Bridgeman's account that I find congenial and compelling, especially appealing is Bridgeman's application of his thesis to the tie between consciousness and language. Nonetheless, I want to raise some questions about whether the tie he finds between plans and consciousness actually does hold. Not all memory and attention is conscious. Although attention and accessing of memories are required to execute plans, we need not be at all conscious of the relevant states of memory and attention. (...) Nor need we be conscious of the objects that those acts of attention and accessed memories are about. We need not necessarily appeal to the executing of plans to explain the important tie between language and consciousness. (shrink)

Speech planning is a sophisticated process. In dialog, it regularly starts in overlap with an incoming turn by a conversation partner. We show that planning spoken responses in overlap with incoming turns is associated with higher processing load than planning in silence. In a dialogic experiment, participants took turns with a confederate describing lists of objects. The confederate’s utterances (to which participants responded) were pre‐recorded and varied in whether they ended in a verb or an object noun and whether this (...) ending was predictable or not. We found that response planning in overlap with sentence‐final verbs evokes larger task‐evoked pupillary responses, while end predictability had no effect. This finding indicates that planning in overlap leads to higher processing load for next speakers in dialog and that next speakers do not proactively modulate the time course of their response planning based on their predictions of turn endings. The turn‐taking system exerts pressure on the language processing system by pushing speakers to plan in overlap despite the ensuing increase in processing load. (shrink)

The idea that natural language grammar and planned action are relatedsystems has been implicit in psychological theory for more than acentury. However, formal theories in the two domains have tendedto look very different. This article argues that both faculties sharethe formal character of applicative systems based on operationscorresponding to the same two combinatory operations, namely functional composition and type-raising. Viewing them in thisway suggests simpler and more cognitively plausible accounts of bothsystems, and suggests that the language faculty (...) evolved in the speciesand develops in children by a rather direct adaptation of a moreprimitive apparatus for planning purposive action in the world bycomposing affordances of objects or tools. Theknowledge representation that underlies such planning is alsoreflected in the natural language semantics of tense, mood, andaspect, which the paper begins by arguing provides the key tounderstanding both systems.

Planning with incomplete knowledge becomes a very active research area since late 1990s. Many logical formalisms introduce sensing actions and conditional plans to address the problem. The action language $\mathcal{A}_{K}$ invented by Son and Baral is a well-known framework for this purpose. In this paper, we propose so-called cautious and weakly cautious semantics for $\mathcal{A}_{K}$ , in order to allow an agent to generate and execute reliable plans in safety-critical environments. Intuitively speaking, cautious and weakly cautious semantics enable the (...) agent to know exactly what happens after the execution of an action. Computational complexity analysis shows that cautious semantics reduces the reasoning complexity of $\mathcal{A}_{K}$ , it is also worth to point out that many useful domains could still be expressed with this setting. Another important contribution of our work is the development of Hoare style proof systems. These proof systems are served as inference mechanisms for the verification of conditional plans, and proved to be sound and complete. In addition, they could also be used for plan generation, in the sense that constructing a derivation is indeed a procedure to finding a plan. We point out that the proof systems posses a nice property for off-line planning, that is, the agent could generate and store short proofs in her spare time, and perform quick plan query by easily constructing a long proof from the stored shorter ones (under the assumption that sufficient proofs are stored).

The term “time-plan” is introduced in the article to sum up the diversity of temporal processes described by Jakob von Uexküll (1864–1944) in the frameworkof the general Planmässigkeit of nature. Although Uexküll hardly had any connections with his contemporary philosophies of time, the theme of the subjectivetimes and timing of the organisms forms an essential part of his umwelt theory. As an alternative to the dominance of evolutionary time in biological discussions, Uexküll took perceptual and developmental times of organisms as (...) his natural scientific priorities. While discussing the characteristics of the latter, Uexküll departs from an epigenetic position. Discussion about perceptual time entails detecting the primary units of time (moments) as well as how the succession of moments results in the perception of movement. The last part of the article will explicate the significance of the “time plan” concept for biophilosophical discussions. It is suggested that the bioethical question rising from Uexküll’s works may take the following form: do other biological subjects besides humans have a right to their own timing? (shrink)

A new theory of problem solving is presented, which embeds problem solving in the theory of action; in this theory, a problem is just a difficult action. Making this work requires a sophisticated language for‐talking about plans and their execution. This language allows a broad range of types of action, and can also be used to express rules for choosing and scheduling plans. To ensure flexibility, the problem solver consists of an interpreter driven by a theorem prover which (...) actually manipulates formulas of the language. Many examples of the use of the system six given. including an extended treatment of the world of blocks. Limitations and extensions of the system are discussed at length. It is concluded that a rule‐based problem solver is necessary and feasible, but that much more work remains to be done on the underlying theory of planning and acting. (shrink)

‘Language and End Time’ is a translation of Sections I, IV and V of ‘Sprache und Endzeit’, a substantial essay by Günther Anders that was published in eight instalments in the Austrian journal FORVM from 1989 to 1991 (the full essay consists of 38 sections). The original essay was planned for inclusion in the third (unrealised) volume of The Obsolescence of Human Beings. ‘Language and End Time’ builds on the diagnosis of ‘our blindness toward the apocalypse’ that (...) was advanced in the first volume of The Obsolescence in 1956. The essay asks if there is a language that is capable of making us fully comprehend the looming ‘man-made apocalypse’. In response to this, it offers a critique of philosophical jargon and of the putatively ‘objective’ language of (nuclear) science, which are both dismissed as unsuitable. Sections I, IV and V introduce this core problematic. The selection of this text for inclusion in this special journal issue responds to present-day realities that inscribe Anders’s reflections on nuclear science and the nuclear situation into new contexts. The critique that ‘Language and End Time’ advances resonates with the way in which the (undemocratic) decisions of a few companies and individuals are shaping the future of life on earth. At the same time, the wider stakes of Anders’s turn against the language employed by (weapons) scientists are newly laid bare by the realities and politics of climate change and fake news. In this new context, the language of science is all too readily dismissed as if it were a mere idiom that can be ignored without consequence. It is against the backdrop of a future that is, if anything, more uncertain than at the time of Anders’s writing, that the essay’s reflections on popularisation, the limits of language and the nature of truth gain added significance.

This paper analyzes the skilled performance of rock climbing through the framework of Embodied and Enacted Cognitive Science. It introduces a notion of enactive planning that is part of one mindful activity of ongoing responsiveness to the affordances of the wall. The paper takes two distinct planning activities involved in rock climbing—route-reading and visualizing—and clarifies them through the enactivist and ecological concepts of nested affordances, prospecting, recalibrating, marking, and corporeal imaginings, as well as Rylean concept of heeding. The paper shows (...) that an enactive approach to planning can make sense of both the planning done in preparation of the climb, and re-planning done during the mindful performance, without invoking additional cognitive architectures.

Language isn't the only way to cross modules, nor is it the only module with access to both input and output. Minds don't generally work across modules because this leads to combinatorial explosion in search and planning. Language is special in being a good vector for mimetics, so it becomes associated with useful cross-module concepts we acquire culturally. Further, language is indexical, so it facilitates computationally expensive operations.

Recent advances in natural language processing have given rise to a new kind of AI architecture: the language agent. By repeatedly calling an LLM to perform a variety of cognitive tasks, language agents are able to function autonomously to pursue goals specified in natural language and stored in a human-readable format. Because of their architecture, language agents exhibit behavior that is predictable according to the laws of folk psychology: they function as though they have desires (...) and beliefs, and then make and update plans to pursue their desires given their beliefs. We argue that the rise of language agents significantly reduces the probability of an existential catastrophe due to loss of control over an AGI. This is because the probability of such an existential catastrophe is proportional to the difficulty of aligning AGI systems, and language agents significantly reduce that difficulty. In particular, language agents help to resolve three important issues related to aligning AIs: reward misspecification, goal misgeneralization, and uninterpretability. (shrink)

We introduce a computational theory of situated language understanding in which the meaning of words and utterances depends on the physical environment and the goals and plans of communication partners. According to the theory, concepts that ground linguistic meaning are neither internal nor external to language users, but instead span the objective‐subjective boundary. To model the possible interactions between subject and object, the theory relies on the notion of perceived affordances: structured units of interaction that can be used (...) for prediction at multiple levels of abstraction. Language understanding is treated as a process of filtering perceived affordances. The theory accounts for many aspects of the situated nature of human language use and provides a unified solution to a number of demands on any theory of language understanding including conceptual combination, prototypicality effects, and the generative nature of lexical items.To support the theory, we describe an implemented system that understands verbal commands situated in a virtual gaming environment. The implementation uses probabilistic hierarchical plan recognition to generate perceived affordances. The system has been evaluated on its ability to correctly interpret free‐form spontaneous verbal commands recorded from unrehearsed game play between human players. The system is able to “step into the shoes” of human players and correctly respond to a broad range of verbal commands in which linguistic meaning depends on social and physical context. We quantitatively compare the system's predictions in response to direct player commands with the actions taken by human players and show generalization to unseen data across a range of situations and verbal constructions.

How is it that many schizophrenics identify certain instances of verbal imagery as hallucinatory? Most investigators have assumed that alterations in sensory features of imagery explain this. This approach, however, has not yielded a definitive picture of the nature of verbal hallucinations. An alternative perspective suggests itself if one allows the possibility that the nonself quality of hallucinations is inferred on the basis of the experience of unintendedness that accompanies imagery production. Information-processing models of “intentional” cognitive processes call for abstract (...) planning representations that are linked to goals and beliefs. Unintended actions - and imagery - can reflect planning disruptions whereby cognitive products do not cohere with concurrent goals. A model of schizophrenic speech disorganization is presented that postulates a disturbance of discourse planning. Insofar as verbal imagery can be viewed as inwardly directed speech, a consequence of such planning disturbances could be the production of unintended imagery. This link between the outward disorganization of schizophrenic speech and unintended verbal imagery is statistically supported by comparing the speech behavior of hallucinating and nonhallucinating schizophrenics. Studies of “borderline” hallucinations during normal, “goal-less” relaxation and drowsiness suggest that experiential unintendedness leads to a nonpathological variant of hallucinatory otherness that is correctable upon emerging from such passive cognitive states. This contrasts with the schizophrenic case, where nonconcordance with cognitive goals reinforces the unintendedness of verbal images and sustains the conviction of an external source. This model compares favorably with earlier models of verbal hallucinations and provides further evidence for a language production disorder in many schizophrenics.Short Abstract: How is it that many schizophrenics identify certain instances of verbal imagery as hallucinatory? This paper proposes that the critical feature identifying hallucinations is the experience of unintendedness. This experience is nonpathological during passive conscious states but pathological if occurring during goal-directed cognitive processing. A model of schizophrenic speech disorganization is presented that postulates a disturbance of discourse planning that specifies communicative intentions. These alterations could generate unintended verbal imagery as well. Statistical data are offered to support the model, and relevant empirical studies are reviewed. (shrink)

We do many things with words. We describe, we plan and promise, we invite and command, we hint and intimate. We also use words to wound – to demean, insult, and exclude. The fact that words can have such potent, pernicious effects is puzzling, because they are, after all, just words. As the schoolyard chant goes, “Sticks and stones may break my bones, but words can never hurt me.” Words do hurt though–not only our feelings, but our social status, even (...) our basic dignity as human beings. How can sounds and shapes do all that? Many philosophers have thought of language as a kind of game. Both games and language are complex, abstract structures that we deploy strategically to achieve serious goals, as well as for fun. Thinking through some of these similarities can illuminate how something so intangible can have such powerful effects, and seeing how people wield that power for malicious ends can reveal how to turn the tables and fight back.

Among philosophers, there are at least two prevalent views about the core concept of intentional action. View I (Adams 1986, 1997; McCann 1986) holds that an agent S intentionally does an action A only if S intends to do A. View II (Bratman 1987; Harman 1976; and Mele 1992) holds that there are cases where S intentionally does A without intending to do A, as long as doing A is foreseen and S is willing to accept A as a consequence (...) of S’s action. Joshua Knobe (2003a) presents intriguing data that may be taken to support the second view.1 Knobe’s data show an asymmetry in folk judgements. People are more inclined to judge that S did A intentionally, even when not intended, if A was perceived as causing a harm (e.g. harming the environment). There is an asymmetry because people are not inclined to see S’s action as intentional, when not intended, if A is perceived as causing a benefit (e.g. helping the environment). In this paper we will discuss Knobe’s results in detail. We will raise the question of whether his ordinary language surveys of folk judgments have accessed core concepts of intentional action. We suspect that instead Knobe’s surveys are tapping into pragmatic aspects of intentional language and its role in moral praise and blame. We will suggest alternative surveys that we plan to conduct to get at this difference, and we will attempt to explain the pragmatic usage of intentional language. (shrink)

Imagine a telephone conversation between a presidential aide and a wealthy supporter, shortly after news breaks that the president plans to veto a bill that the supporter strongly favors. The nervous aide opens with “I'm calling to let you know that the president regrets his, uh, his decision…” The supporter's hopes rise at the intimation that the president changed his mind. But when the aide continues: “… did not meet with your apparel, I mean, your approval,” the crestfallen (and, perhaps, (...) former) supporter realizes that the president is sorry merely about the impact of his decision, not the decision itself. The aide's utterance seems to mean one thing at first, but something entirely different in the end. Unintentional verbal about‐faces of this kind are common in everyday language use – the outspoken owner of an American baseball team recently said that she regretted her remarks offended many people – yet listeners rarely notice the miscues, the wealthy supporter notwithstanding. This is one of the chief motivations behind the psycholinguistic study of language use. (shrink)

We investigate the timing of pre-answer inbreaths in order to shed light on the time course of response planning and execution in conversational turn-taking. Using acoustic and inductive plethysmography recordings of seven dyadic conversations in Dutch, we show that pre-answer inbreaths in conversation typically begin briefly after the end of questions. We also show that the presence of a pre-answer inbreath usually co-occurs with substantially delayed answers, with a modal latency of 576 vs. 100 ms for answers not preceded by (...) an inbreath. Based on previously reported minimal latencies for internal intercostal activation and the production of speech sounds, we propose that vocal responses, either in the form of a pre-utterance inbreath or of speech proper when an inbreath is not produced, are typically launched in reaction to information present in the last portion of the interlocutor's turn. We also show that short responses are usually made on residual breath, while longer responses are more often preceded by an inbreath. This relation of inbreaths to answer length suggests that by the time an inbreath is launched, typically during the last few hundred milliseconds of the question, the length of the answer is often prepared to some extent. Together, our findings are consistent with a two-stage model of response planning in conversational turn-taking: early planning of content often carried out in overlap with the incoming turn, and late launching of articulation based on the identification of turn-final cues.

In lieu of an abstract, here is a brief excerpt of the content:Towards Language Justice:A Call to Identify and Overcome Structural BarriersFelicity RatwayThe patient I am interpreting for praises my interpretation. I've done nothing particularly noteworthy to merit her praise; I followed basic ethical tenets, nothing more. Hearing everything the provider says rather than a brief synopsis exceeds her expectations after many experiences working with untrained interpreters, or being refused interpreting services altogether. The bar shouldn't be this low.I am (...) exhausted. Like most interpreters, I am an independent contractor. I must work 5 am–9 pm to get paid for 8 hours of work. With some language companies, I earn less than minimum wage. To many new interpreters, $35 per hour sounds great—then they realize that driving to and from a one-hour appointment involves two hours of unpaid drive time. In rural areas, this really takes a toll. I spend hours checking pay stubs; I find errors nearly every pay period, but I wouldn't have a court case for the repeated underpayments because when I reach out to ask for the errors to be fixed, they are eventually corrected. Despite my state and national certifications and Master's degree in Interpreting and Translation Studies, medical interpreting doesn't pay the bills. I supplement my income through multiple other jobs.Laws intended to protect the patients we work with as interpreters are seldom enforced. Title VI Guidance defines a competent interpreter as one who has been trained, demonstrated proficiency, demonstrated interpreting skills, and agrees to abide by ethical standards. Patients fare better when competent interpreters are available, but when most patient and provider experiences are with interpreters who haven't met competency standards, patients and providers (understandably) lose trust in the profession. The profession has few opportunities for advancement and struggles to attract interpreters to go through rigorous training or build a long-term career. Skilled interpreters soon leave for greener pastures: the Oregon Health Authority (OHA) houses a registry of interpreters who meet minimum state training and proficiency requirements, and a 2019–2021 study found that roughly 92% of interpreters due to renew dropped off of the registry instead.When I began interpreting, I was shocked by how infrequently laws protecting patients' rights to interpreting services were followed in practice. At primary care appointments, patients often cannot answer questions about specialist visits because interpretation was not provided at the specialist's office. I knew recipients of federal funds couldn't [End Page 164] legally bill patients for interpreting services, yet I was asked to sight-translate paperwork that stated patients would be billed for interpreting services if they were late to an appointment. I reported the issue; years later, the same paperwork would still appear on their public-facing website. I discovered that though state law required credentialed interpreters to be made available, no agency had been tasked with enforcing that law; all that could be done with my complaint was to refer it to the patient's insurance company.In Oregon, Coordinated Care Organizations (CCOs) manage Medicaid plans, and are required to pay for interpreting services for their members. Instead of hiring interpreters directly, many contract with language companies that, in turn, hire us. Providers must book interpreters through the specific language companies contracted with the patient's CCO to avoid paying for the interpreter themselves. I am often called to interpret for speakers of indigenous languages even though I am not able to meet their needs as a Spanish interpreter. I offer contact information for organizations that could provide interpretation in the appropriate language, but the receptionist tells me that she can only go through specific vendors because the clinic doesn't want to have to pay out-of-pocket. Indigenous-led organizations that pay indigenous interpreters a living wage are not contracted with the CCOs in my region. In some cases, when interpreters are not available for a particular language through the CCO's preferred vendor, providers instead ask that an appointment be rescheduled, hoping that an interpreter will be available later. I have seen speakers of rare languages seeking primary care end up in the hospital after being rescheduled several times.Providers I work with often don't know... (shrink)

When the language-dominant hemisphere is damaged by a focal lesion, the brain may reorganize the language network through functional and structural changes known as adaptive plasticity. Adaptive plasticity is documented for triggers including ischemic, tumoral, and epileptic focal lesions, with effects in clinical practice. Many questions remain regarding language plasticity. Different lesions may induce different patterns of reorganization depending on pathologic features, location in the brain, and timing of onset. Neuroimaging provides insights into language plasticity due (...) to its non-invasiveness, ability to image the whole brain, and large-scale implementation. This review provides an overview of language plasticity on MRI with insights for patient care. First, we describe the structural and functional language network as depicted by neuroimaging. Second, we explore language reorganization triggered by stroke, brain tumors, and epileptic lesions and analyze applications in clinical diagnosis and treatment planning. By comparing different focal lesions, we investigate determinants of language plasticity including lesion location and timing of onset, longitudinal evolution of reorganization, and the relationship between structural and functional changes.

This paper explores the truism that people think about what they say. It proposes that, to satisfy their own goals, people often plan their speech acts to affect their listeners' beliefs, goals, and emotional states. Such language use can be modelled by viewing speech acts as operators in a planning system, thus allowing both physical and speech acts to be integrated into plans. Methodological issues of how speech acts should be defined in a planbased theory are illustrated by defining (...) operators for requesting and informing. Plans containing those operators are presented and comparisons are drawn with Searle's formulation. The operators are shown to be inadequate since they cannot be composed to form questions (requests to inform) and multiparty requests (requests to request). By refining the operator definitions and by identifying some of the side effects of requesting, compositional adequacy is achieved.The solution leads to a metatheoretical principle for modelling speech acts as planning operators.

We describe how Intuitionistic Linear Logic can be used to provide a unified logical account for agents to find and execute plans. This account supports the modelling of agent interaction, including dialogue; allows agents to be robust to unexpected events and failures; and supports significant reuse of agent specifications. The framework has been implemented and several case studies have been considered. Further applications include human–computer interfaces as well as agent interaction in the semantic web.

Discourse connection is a challenging aspect of writing in a second language. This study seeks to investigate the effects of two classroom instructions on discourse connection in writing for EFL college students, focusing on their argumentative writing. Three classes were exposed to different pre-task conditions: receiving reading materials that provide content support for the writing, receiving planning instructions on effective outlining, and receiving no resources. The results showed that the instructions helped students attain better overall coherence in writing. However, (...) noticeable differences between the two experimental groups emerged in terms of cohesion features. The reading group was found to employ more lexical cohesion devices in writing than the outline group, which indicated a heightened genre awareness. This inquiry helped us identify the reading group’s alignment with content support materials, particularly the change in stance as a factor that contributes to a higher level of lexical cohesion in writing.

In “Avoiding a Death Panel Redux,” Nicole Piemonte and Laura Hermer make the argument that the advance care planning consultation provision during the health care reform debate collapsed both because the language in the provision was deliberately misread and because some features of the language could in fact be misleading. We agree on both counts. We add that the cost‐effectiveness provisions of the bill make us face difficult decisions we as a nation would rather avoid, but can and (...) must face squarely and together. It is time for an honest national conversation about at least two issues concerning medical care near the end of life. First, talking about or planning a good death with your doctor or nurse will not make death happen sooner. The data show that better planning for a well‐managed terminal illness leads to longer life as well as better symptom control and less distress. Second, we need to quickly and directly confront the cost of end of life care in the United State, recognize the political consequences, and work with the broad middle to advance the common good.

1. What's in a Name?Can philosophy of language do without the concept of intentionality? To approach this important question it may be useful to begin with the minimal explanatory requirements for a theory of reference that tries to explain the naming of objects as the simplest linguistic act. The limitations of trying to understand meaning without intentionality are therefore best illustrated by considering what is generally acknowledged to be the most thorough-going attempt to dispense altogether with intentional concepts in (...) Frege's reputedly purely extensionalist semantics of proper names. I shall argue that despite his avowed anti-psychologism, Frege paradoxically needs to include psychological elements alongside his famous distinction between sense and reference in order to preserve the universal intersubstitutability of singular referring expressions salva veritate as an adequate extensional criterion of coreferentiality. In so doing, a revisionary Fregean semantics introduces the first instalment of intentionality at the foundations of naming, by which intentionality pervades the philosophy of language. (shrink)

Research on language production has focused on the process of utterance planning and involved studying the synchronization between visual gaze and the production of sentences that refer to objects in the immediate visual environment. However, it remains unclear how the visual grouping of these objects might influence this process. To shed light on this issue, the present research examined the effects of the visual grouping of objects in a visual display on utterance planning in two experiments. Participants produced utterances (...) of the form “The snail and the necklace are above/below/on the left/right side of the toothbrush” for objects containing these referents (e.g., a snail, a necklace and a toothbrush). These objects were grouped using classic Gestalt principles of color similarity (Experiment 1) and common region (Experiment 2) so that the induced perceptual grouping was congruent or incongruent with the required phrasal organization. The results showed that speech onset latencies were shorter in congruent than incongruent conditions. The findings therefore reveal that the congruency between the visual grouping of referents and the required phrasal organization can influence speech production. Such findings suggest that, when language is produced in a visual context, speakers make use of both visual and linguistic cues to plan utterances. (shrink)

This article deals primarily with the examination of two key and exegetically demanding expressions in the text of the General Epistle of James, which relate to fundamental biblical principles on planning the future of the believer and reconciling human life with God’s will expressed in Holy Scripture. The first one is the hapax legomenon Ἄγε νῦν, the significance of which is closely related to updating of the affected principles with practice. The second term is ποιήσοµεν, which, in most translations, translates (...) as ‘remain’ and does not reflect the core idea of the examined verse. We prove that a more authentic and appropriate translation is ‘work’. Our aim was to find out what new interpretive possibilities the original biblical text offers. The constitutive starting point for research is Novum Testamentum Graecum – Editio Critica Maior. We then compared these texts with the Slovak Ecumenical Bible. The method of our exegetical work was not primarily comparison, but a linguistic analysis and historical-critical exegesis, the result of which is a completely new proposal for the translation of the scrutinised texts. Auxiliary materials were the most important patristic and exegetical commentaries. In conclusion, we state that the analysis made it possible to find a new translation of the researched text, which can really contribute to the improvement of further review and publication of the ecumenical translation of the Bible into various languages.Contribution: The article examines the source Greek biblical text of James 4:13–15 and reveals a new interpretation of it. This interpretation brings a new, biblical light into the field of planning, which is one of the most current topics nowadays. With its content and especially its conclusions, it contributes to the goals of this theological journal, the subject of which is also the research of Greek biblical manuscripts. (shrink)
