The contemporary debate about truth is polarized between deflationists and those who offer robust accounts of truth. I present a theory of truth called ‘Primitive Disclosive Alethism’ that occupies the middle ground between these two extremes. Contrary to deflationist claims, truth has a nature beyond its merely linguistic, expressive function. Truth is objective and non-epistemic, yet cannot be characterized in terms of correspondence. Primitive Disclosive Alethism offers a metaphysically satisfying explanation of our correspondence intuitions, while explaining why the concept of (...) truth is an undefined primitive. The theory also explains why the T-schema offers the clearest expression of what makes a sentence true. I distinguish this theory from the Identity Theory of Truth which equates true propositions with facts. (shrink)

There is relatively little comprehensive treatment of Heidegger’s theory of essences despite his ubiquitous use of essences. It is commonplace in contemporary analytic philosophy to view essences as the ground for true de re modal claims. I argue that Heidegger offers an account of essences that can best be understood as a type of relative essentialism. Relative essentialism is the view that more than one being can occupy the same space at the same time and those beings have distinct sets (...) of de re modal truths about them. Heidegger’s account of essences allows for true de re modal claims about a wide variety of things including scientific and cultural entities. At the same time, Heidegger rejects absolute essentialism: the view that there is one privilege collection of beings whose natures determine the truth values of de re modal claims about them. Relative essentialism is distinguished from contextual essentialism. (shrink)

Davidson, truth, and triangulation -- Davidson applied -- Half truths -- Heidegger's analytic of Dasein -- Dasein and truth -- Truthful intersections -- Primitive disclosive alethism.

Recent literature comparing the works of Heidegger and Davidson suggests that one of the main differences between these two thinkers is that the latter lacks any notion of non-linguistic interpretation and understanding; the only way of making sense of a domain of entities for Davidson is theory. I argue against this common perspective and show that Davidson is committed to a primitive, pre-conceptual form of understanding that is socially mediated. This primitive form of understanding is essential to the functioning of (...) what Davidson calls 'primitive triangulation'. Properly understood, primitive triangulation shares many structural features with Dasein's comportment. (shrink)

This is essay is a critical response to Zhang Longxi's argument that Taoist philosophy is susceptible to Derrida's arguments against logocentrism. I present two main arguments. First, I argue that Zhang fails to provide sufficient evidence that would show Taoism is logocentric. Moreover, even if Zhang could provide support for such a claim there cannot be a general deconstructive argument against logocentrism. Derrida's arguments against logocentrism work from within a specific text. The second argument offers reasons for believing Taoism is (...) decidedly not logocentric because it lacks, among other things, the phonocentrism Derrida was intent on criticising. The 'presence' mentioned in Taoist literature is antithetical to the Platonic notion of Forms; it is not the presence of unchanging ideas in a rational mind. Zhuangzi and Plato do not share the similarities attributed to them by Zhang. (shrink)

This paper critically evaluates the arguments advanced by Hubert Dreyfus in his debate with John McDowell regarding the nature of skilled coping. The paper argues that there are significant methodological shortcomings in Dreyfus’ position. The paper examines these methodological limitations and attempts to clarify the problems by re-framing the issues in terms of intentionality, and the specific intentional structures that may or may not be present in skilled coping. The paper attempts to show that the difficulties facing Dreyfus arise from (...) his implicit adherence to a final myth of the mental. The last myth of the mental is the belief thatmental coping is fundamentally different than embodied coping because the former is characterized by mindedness while the latter is not. Dreyfus characterizes the mental as constituted by a kind of interiority while everyday expertise or embodied coping is characterized by exteriority to the exclusion of any type of interiority. I undermine this Cartesian assumption in Dreyfus’ position by showing that the criteria and phenomenological descriptions he uses to characterize embodied coping apply equally to mental coping.

Donald Davidson assigns truth a central role in his theory of meaning but he also makes truth a guiding methodological principle in metaphysics. Truth is inexorably connected to belief and meaning, and no one of these concepts has theoretical priority over the others. I argue that there is a methodological circularity in Davidson’s account of how the world contributes to the truth of our beliefs and utterances. The difficulty for Davidson is in providing an account of how speakers share a (...) common world while denying an ontologically privileged domain of entities and further claiming that being supervenes on truth. I suggest that the Heideggerian notion of disclosedness offers one solution. (shrink)

The dissertation examines Davidson and Heidegger's rejections of correspondence truth, as well as their claims that truth is theoretically primitive. Truth is primitive in the sense that it cannot be reduced to, nor defined in terms of, some other more theoretically basic concepts, such as those offered in correspondence, coherence, and pragmatic accounts of truth. The fact that truth cannot be defined in terms of more basic concepts does not mean that there are not important and meaningful things to say (...) about truth; Davidson and Heidegger's agreement that there is more to say about truth distinguishes them from minimalist approaches to truth. Davidson and Heidegger make explicit truth's conceptual relationship to other important areas of inquiry such as language, subjectivity, and ontology. The dissertation claims that the two philosophers agree, despite radically different background texts and methodologies, on the fundamental relationship between self, other, and world. The dissertation moves beyond mere comparison by showing that Davidson's own position commits him to a Heideggerian treatment of truth, or something like it. I argue that understanding the similarities and supplemental arguments offered by each philosopher leads to a better overall account of truth than that offered by each philosopher individually. Moreover, I argue that although Heidegger and Davidson offer primarily transcendental arguments, their theories can accommodate naturalistic theories of language and concept acquisition. (shrink)

This paper offers a deconstructive analysis of the work of Mitra Gholamain and Keith Oatley. The authors’ treatment of fiction as a simulation of psychic reality can be inverted; psychic reality is already constituted by non-literal narrative elements. I offer empirical considerations drawn from current psychological literature. The relationship between readers’ psychology and works of narrativefiction is a constitutive structural similarity, rather than simply a psychological process of simulation.

Relative essentialism is the novel metaphysical theory that there can be multiple objects occupying the same space at the same time each with its own de re modal truths. Relative essentialism is motivated by Davidson’s semantics and his denial that nature itself is divided into a privileged domain of objects. Relative essentialism was first presented by Samuel C. Wheeler. I argue that Wheeler’s approach to the Davidsonian program needs to be elaborated in terms of various types of preconceptual intentional relations. (...) This elaboration is already largely implicit in Davidson’s own later work and in Wheeler’s relaunching of Davidsonian metaphysics. More specifically, I argue that relative essentialism is ultimately founded not on predication narrowly construed but on intentionality broadly construed. Following Wheeler’s suggestion, comparisons are made between relative essentialism and work within the phenomenological tradition. (shrink)

Alethic pluralists argue truth is a metaphysically robust higher-order property that is multiply realized by a set of diverse and domain-specific subvening alethic properties. The higher-order truth property legitimizes mixed inferences and accounts for a univocal truth predicate. Absent of this higher-order property, pluralists lack an account of the validity of mixed inferences and an adequate semantics for the truth predicate and thereby appear forced to abandon the central tenets of alethic pluralism. I argue the use of many-valued logics to (...) support pluralism fails to address the pluralist’s metaphysical problem regarding mixed inferences and mixed truth functional connectives. The high degree of heterogeneity of the alethic realizers challenges the plausibility of a single higher-order functional property. A functional property with such a heterogeneous base cannot be projectable at a theoretically significant level. The problem with mixed inferences and truth functions is but one symptom of the deeper projectability problem. (shrink)

Davidson’s 1974 argument denying the possibility of incommensurable conceptual schemes is widely interpreted as entailing a denial of metaphysical pluralism. Speakers may group objects differently or have different beliefs about the world, but there is just one world. I argue there is tension arising from three aspects of Davidson’s philosophy: the 1974 argument against conceptual schemes; Davidson’s more recent emphasis on primitive triangulation as a necessary condition for thought and language; and Davidson’s semantic approach to metaphysics, what he calls ‘the (...) method of truth in metaphysics’. After elucidating the tension, I argue the tension can be resolved while preserving at least two major tenets of Davidson’s philosophy: conceptual schemes do not carve an uninterpreted reality into different worlds and truth is objective and non-epistemic. I argue Davidson is implicitly committed to a plurality of worlds. (shrink)

Previous research has suggested that bodily signals from internal organs are associated with diverse cortical and subcortical processes involved in sensory-motor functions, beyond homeostatic reflexes. For instance, a recent study demonstrated that the preparation and execution of voluntary actions, as well as its underlying neural activity, are coupled with the breathing cycle. In the current study, we investigated whether such breathing-action coupling is limited to voluntary motor action or whether it is also present for mental actions not involving any overt (...) bodily movement. To answer this question, we recorded electroencephalography (EEG), electromyography (EMG), and respiratory signals while participants were conducting a voluntary action paradigm including self-initiated motor execution (ME), motor imagery (MI), and visual imagery (VI) tasks. We observed that the voluntary initiation of ME, MI, and VI are similarly coupled with the respiration phase. In addition, EEG analysis revealed the existence of readiness potential (RP) waveforms in all three tasks (i.e., ME, MI, VI), as well as a coupling between the RP amplitude and the respiratory phase. Our findings show that the voluntary initiation of both imagined and overt action is coupled with respiration, and further suggest that the breathing system is involved in preparatory processes of voluntary action by contributing to the temporal decision of when to initiate the action plan, regardless of whether this culminates in overt movements. -/- .

At any given time, a subject has a multiplicity of conscious experiences. A subject might simultaneously have visual experiences of a red book and a green tree, auditory experiences of birds singing, bodily sensations of a faint hunger and a sharp pain in the shoulder, the emotional experience of a certain melancholy, while having a stream of conscious thoughts about the nature of reality. These experiences are distinct from each other: a subject could experience the red book without the singing (...) birds, and could experience the singing birds without the red book. But at the same time, the experiences seem to be tied together in a deep way. They seem to be unified, by being aspects of a single encompassing state of consciousness. (shrink)

Disorders of volition are often accompanied by, and may even be caused by, disruptions in the phenomenology of agency. Yet the phenomenology of agency is at present little explored. In this paper we attempt to describe the experience of normal agency, in order to uncover its representational content.

The neurotransmitters GABA and glutamate have been suggested to play a role in Major Depressive Disorder (MDD) through an imbalance between cortical inhibition and excitation. This effect has been highlighted in higher brain areas, such as the prefrontal cortex, but has also been posited in basic sensory cortices. Based on this, magnetic resonance spectroscopy (MRS) was used to investigate potential changes to GABA+ and glutamate+glutamine (Glx) concentrations within the occipital cortex in MDD patients (n = 25) and healthy controls (n (...) = 25). No difference in occipital GABA+ or Glx concentrations, nor in the GABA+/Glx ratio, was found between groups. An analysis of an extended MDD patient and unmatched control dataset (n = 90) found no correlation between metabolite concentrations and depressive symptoms. These results were integrated with prior studies through metabolite-specific meta-analyses, revealing no difference in occipital GABA and Glx concentrations between patients and controls. An effect of publication year on GABA group differences was found, suggesting that previously reported results may have been artifacts of measurement accuracy. Taken together, our results suggest that, contrary to some prior reports, MRS measurements of occipital GABA and Glx do not differ between MDD patients and controls. (shrink)

Neurovascular coupling (NVC), the transient regional hyperemia following the evoked neuronal responses, is the basis of blood oxygenation level-dependent techniques and is generally adopted across physiological conditions, including the intrinsic resting state. However, the possibility of neurovascular dissociations across physiological alterations is indicated in the literature. To examine the NVC stability across sleep–wake states, we used electroencephalography (EEG) as the index of neural activity and functional magnetic resonance imaging (fMRI) as the measure of cerebrovascular response. Eight healthy adults were recruited (...) for simultaneous EEG-fMRI recordings in nocturnal sleep. We compared the cross-modality (EEG vs. fMRI) consistency of functional indices (spectral amplitude and functional connectivity) among five states of wakefulness and sleep (state effect). We also segregated the brain into three main partitions (anterior, middle and posterior) for spatial assessments (regional effect). Significant state effects were found on δ, α and fMRI indices and regional effects on the α and fMRI indices. However, the cross-state EEG changes in spectral amplitude and functional connectivity did not consistently match the changes in the fMRI indices across sleep–wake states. In spectral amplitude, the δ band peaked at the N3 stage for all brain regions, while the fMRI fluctuation amplitude peaked at the N2 stage in the central and posterior regions. In regional connectivity, the inter-hemispheric connectivity of the δ band peaked at the N3 stage for all regions, but the bilateral fMRI connectivity showed the state changes in the anterior and central regions. The cross-modality inconsistencies across sleep–wake states provided preliminary evidence that the neurovascular relationship may not change in a linear consistency during NREM sleep. Thus, caution shall be exercised when applying the NVC presumption to investigating sleep/wake transitions, even among healthy young adults. (shrink)

Objective Manic and depressive phases of bipolar disorder (BD) show opposite psychomotor symptoms. Neuronally, these may depend on altered relationships between sensorimotor network (SMN) and subcortical structures. The study aimed to investigate the functional relationships of SMN with substantia nigra (SN) and raphe nuclei (RN) via subcortical-cortical loops, and their alteration in bipolar mania and depression, as characterized by psychomotor excitation and inhibition. -/- Method In this resting-state functional magnetic resonance imaging (fMRI) study on healthy (n = 67) and BD (...) patients (n = 100), (1) functional connectivity (FC) between thalamus and SMN was calculated and correlated with FC from SN or RN to basal ganglia (BG)/thalamus in healthy; (2) using an a-priori-driven approach, thalamus-SMN FC, SN-BG/thalamus FC, and RN-BG/thalamus FC were compared between healthy and BD, focusing on manic (n = 34) and inhibited depressed (n = 21) patients. -/- Results (1) In healthy, the thalamus-SMN FC showed a quadratic correlation with SN-BG/thalamus FC and a linear negative correlation with RN-BG/thalamus FC. Accordingly, the SN-related FC appears to enable the thalamus-SMN coupling, while the RN-related FC affects it favoring anti-correlation. (2) In BD, mania showed an increase in thalamus-SMN FC toward positive values (ie, thalamus-SMN abnormal coupling) paralleled by reduction of RN-BG/thalamus FC. By contrast, inhibited depression showed a decrease in thalamus-SMN FC toward around-zero values (ie, thalamus-SMN disconnection) paralleled by reduction of SN-BG/thalamus FC (and RN-BG/thalamus FC). The results were replicated in independent HC and BD datasets. -/- Conclusions These findings suggest an abnormal relationship of SMN with neurotransmitters-related areas via subcortical-cortical loops in mania and inhibited depression, finally resulting in psychomotor alterations.

In this paper we defend the doxastic conception of delusions against the metacognitive account developed by Greg Currie and collaborators. According to the metacognitive model, delusions are imaginings that are misidentified by their subjects as beliefs: the Capgras patient, for instance, does not believe that his wife has been replaced by a robot, instead, he merely imagines that she has, and mistakes this imagining for a belief. We argue that the metacognitive account is untenable, and that the traditional conception of (...) delusions as beliefs should be retained. (shrink)

We will introduce a partial ordering $\preceq_1$ on the class of ordinals which will serve as a foundation for an approach to ordinal notations for formal systems of set theory and second-order arithmetic. In this paper we use $\preceq_1$ to provide a new characterization of the ubiquitous ordinal $\epsilon _{0}$.

One of the fundamental components of the concept of economic rationality is that preference orderings are “complete,” i.e., that all alternative actions an economic agent can take are comparable. The idea that all actions can be ranked may be called the single utility assumption. The attractiveness of this assumption is considerable. It would be hard to fathom what choice among alternatives means if the available alternatives cannot be ranked by the chooser in some way. In addition, the efficiency criterion makes (...) sense only if one can infer that an individual's choice reflects the best, in expected welfare terms, among all choices that individual could have made. The possibility that a rearrangement of resources could make someone “better off” without making others “worse off” can be understood only if the post-rearrangement world is comparable with the pre-rearrange-ment world.

We will investigate patterns of resemblance of order 2 over a family of arithmetic structures on the ordinals. In particular, we will show that they determine a computable well ordering under appropriate assumptions.

In this study, three individual descriptions of anxiety as experienced in social situations were analyzed so that a general structure representing social anxiety could potentially be obtained. The descriptions analyzed produced results that not only overlapped with already existing literature from various perspectives on the topic, but also highlighted certain key factors that have largely been unaccounted for by prior studies. By utilizing the Descriptive Phenomenological Method in Psychology , these factors were brought to light in more depth and clarity (...) than if the same phenomenon were studied using a third person approach. Specifically, six constituents of social anxiety were revealed; including factors related to inter-subjectivity, the relationship between fear and anxiety, and the relationship between desire and self-lack.

Background Neuroimaging and lesion studies suggested that the dorsolateral prefrontal and posterior parietal cortices mediate visual metacognitive awareness. The causal evidence provided by non-invasive brain stimulation, however, is inconsistent. -/- Objective/hypothesis Here we revisit a major figure discrimination experiment adding a new Kanizsa figure task trying to resolve whether bilateral continuous theta-burst transcranial magnetic stimulation (cTBS) over these regions affects perceptual metacognition. Specifically, we tested whether subjective visibility ratings and/or metacognitive efficiency are lower when cTBS is applied to these two (...) regions in comparison to an active control region. -/- Methods A within-subjects design including three sessions spaced by one-week intervals was implemented. In each session, every participant was administered bilateral cTBS to either prefrontal, control or parietal cortices. Two concurrent tasks were performed, a real and an illusory figure task, stabilising objective performance with use of an adaptive staircase procedure. -/- Results When performing the replicated task, cTBS was found insufficient to disrupt neither visibility ratings nor metacognitive efficiency. However, with use of Kanizsa style illusory figures, cTBS over the dorsolateral prefrontal, but not over the posterior parietal cortex, was observed to significantly diminish metacognitive efficiency. -/- Conclusion(s) Real and illusory figure tasks demonstrated different cTBS effects. A possible explanation is the involvement of the prefrontal cortex in the creation of expectations, which is necessary for efficient metacognition. Failure to replicate previous findings for the real figure task, however, cannot be said to support, conclusively, the notion that these brain regions have a causal role in metacognitive awareness. This inconsistent finding may result from certain limitations of our study, thereby suggesting the need for yet further investigation. (shrink)

A notation for an ordinal using patterns of resemblance is based on choosing an isominimal set of ordinals containing the given ordinal. There are many choices for this set meaning that notations are far from unique. We establish that among all such isominimal sets there is one which is smallest under inclusion thus providing an appropriate notion of normal form notation in this context. In addition, we calculate the elements of this isominimal set using standard notations based on collapsing functions. (...) This provides a capstone to the results in [2, 6, 8, 9, 7], using further refinement of ordinal arithmetic developed in [8] which then both allows for a simple characterization of normal forms for patterns of order one and will play a key role in the arithmetical analysis of pure patterns of order two, [5].

Physiological studies of binocular rivalry have provided important clues to the relationship between neural activity in the brain and visual awareness.However, uncertainty about these insights has been raised by a recent study showing that the events underlying binocular rivalry occur earlier in the visual pathway than was previously thought.

The target paper by Noë and Thompson is a very welcome addition to the literature on the neural correlates of consciousness. It raises a number of important issues, and the debate it will generate should go some way towards clarifying the conceptual terrain that we’re in. In this commentary I focus on three issues: the link between isomorphism and the matching-content doctrine; the argument against the matching-content doctrine; and the argument against experiential internalism.

ABSTRACT:Drawing upon the collective action model of institutional change, I reconceptualize moral imagination as both a social process and a cognitive one. I argue that moral outcomes are not produced by individual actors alone; rather, they emerge from collective action processes that are influenced by political conditions and involve behaviors that include issue framing and resource mobilization. I also contend that individual moral imagination involves the integration of moral sensitivity with consideration of collective action dynamics. I illustrate my arguments with (...) a case study of the Chad-Cameroon oil project. The paper suggests new directions in teaching and research on moral imagination. (shrink)
