Western Buddhists often believe and proclaim that metaphysical speculation is irrelevant to Buddhist ethics or practice. This view is problematic even with respect to early Buddhism, and cannot be sustained regarding later Indian Buddhists. In Śāntideva’s famous Bodhicaryāvatāra, multiple claims about the nature of reality are premises for conclusions about how human beings should act; that is, metaphysics logically entails ethics for Śāntideva, as it does for many Western philosophers. This article explores four key arguments that Śāntideva makes from metaphysics (...) to ethics: actions are determined by their causes, and therefore we should not get angry; the body is reducible to its component parts, and therefore we should neither protect it nor lust after other bodies; the self is an illusion, and therefore we should be altruistic; all phenomena are empty, and therefore we should not be attached to them. The exploration of these arguments together shows us why metaphysical claims can matter a great deal for Buddhist ethics, practice and liberation. (shrink)

This dissertation examines the idea of _ethical revaluation_ — taking things we normally see as good for our flourishing and seeing them as neutral or bad, and vice versa — in the Mahāyāna Buddhist thinker Śāntideva. It shows how Śāntideva’s thought on the matter is more coherent than it might otherwise appear, first by examining the consistency of Śāntideva’s own claims and then by applying them to contemporary ethical thought. In so doing, it makes four significant contributions. Śāntideva claims that (...) property and relationships are bad for us because they promote attachment, and that others’ wrongdoing is good for us because it allows us to generate patient endurance. Yet he also urges his readers to give property to others, and to prevent their wrongdoing. Is he caught in contradiction? The dissertation argues that he is not, because giving to others is not intended to benefit them materially, but rather to produce beneficial mental states in them, and preventing wrongdoing is intended to benefit the wrongdoer and not the victim. In both cases, Śāntideva emphasizes individual action in a way that makes social or political action more difficult to justify. The dissertation’s first contribution is to show how this interpretation of Śāntideva contrasts notably with standard presentations of Mahāyāna ethics. Its second contribution is to refute claims that Buddhists have no normative ethics. Śāntideva’s resolutions of these apparent contradictions also have relevance for contemporary ethical thought. Martha Nussbaum argues against an ethical revaluation similar to Śāntideva’s, on the grounds that such a revaluation makes it contradictory to argue for providing goods to others, preventing others’ wrongdoing or engaging in political action. Śāntideva’s views show that ethical revaluation is a more sustainable position than these criticisms of Nussbaum’s would imply; if it is to be rejected, it must be rejected on other grounds. To show this point is the dissertation’s third contribution. The fourth contribution is methodological; by finding similarities of concern and differences of opinion between Śāntideva and a contemporary thinker, it helps bridge the gap between normative and comparative religious ethics.

Śāntideva's Bodhicaryāvatāra is an extraordinary text. Its ethical arguments, with their metaphysical grounding, are among the most explicit in classical Indian literature. This fact alone is sufficient to place the BCA among the most important texts of classical Indian philosophy. But the BCA's importance goes well beyond philosophy as such, as the Readings volume reviewed here shows amply: it is a work of poetic and literary brilliance with ritual and meditative significance in Tibet and elsewhere. (There is nothing wrong with (...) the Readings volume's English translation of the title as... (shrink)

The Mahāyāna Buddhist thinker Śāntideva tells his audience to give out alcohol, weapons and sex for reasons of Buddhist compassion, though he repeatedly warns of the dangers of all these three. The article shows how Śāntideva resolves this issue: these gifts, and gifts in general, attract their recipients to the virtuous giver, in a way that helps the recipients to become more virtuous in the long run. As a consequence, Śāntideva does recommend the alleviation of poverty, but assigns it a (...) much smaller significance than is usually supposed. His views run counter to many engaged Buddhist discussions of political action, and lend support to the “modernist” interpretation of engaged Buddhist practice. (shrink)

Ken Wilber insists that valid knowledge must be derived from paradigms: sets of injunctions and social practices that lead to replicable experiences. In this article, I examine Wilber's claims that the theory still includes the essentials of premodern traditions, because the essentials of those traditions consist of a phenomenological core of practices leading to mystical experience. Drawing on the works of Robert Sharf and Wilhelm Halbfass and on close readings of primary texts, this article argues that mystical paradigms of replicable (...) experience are not in fact the essentials of these traditions--neither for the majority of practitioners nor even for their revered teachers or masters. The article concludes with a discussion of the implications of this point for constructive integral work. (shrink)

An encyclopedia article about Śāntideva, the 8th-century Indian Mahāyāna Buddhist philosopher known for his work on ethics. The article explores his history and written corpus and classifies his work (as he does) by way of the "perfections" (pāramitā) of the bodhisattva. It addresses his views on metaphysics and their implications for ethics and practice, as well as his views on gift-giving, anger and other emotions. It also briefly discusses his relationship to virtue ethics and consequentialism.

Contemporary engaged Buddhist scholars typically claim either that Buddhism always endorsed social activism, or that its non-endorsement of such activism represented an unwitting lack of progress. This article examines several classical South Asian Buddhist texts that explicitly reject social and political activism. These texts argue for this rejection on the grounds that the most important sources of suffering are not something that activism can fix, and that political involvement interferes with the tranquility required for liberation. The article then examines the (...) history of engaged Buddhism in order to identify why this rejection of activism has not yet been taken sufficiently seriously. (shrink)

Amodal completion is the representation of those parts of the perceived object that we get no sensory stimulation from. While amodal completion is rife and plays an essential role in all sense modalities, philosophical discussions of this phenomenon have almost entirely been limited to vision. The aim of this paper is to examine in what sense we can talk about amodal completion in olfaction. We distinguish three different senses of amodal completion – spatial, temporal and feature-based (...) completion – and argue that all three are present and play a significant role in olfaction. (shrink)

Amodal completion is usually characterized as the representation of those parts of the perceived object that we get no sensory stimulation from. In the case of the visual sense modality, for example, amodal completion is the representation of occluded parts of objects we see. I argue that relationalism about perception, the view that perceptual experience is constituted by the relation to the perceived object, cannot give a coherent account of amodal completion. The relationalist has two options: construe (...) the perceptual relation as the relation to the entire perceived object or as the relation to the unoccluded parts of the perceived object. I argue that neither of these options are viable. (shrink)

Amodal completion is the representation of occluded parts of perceived objects. We argue for the following three claims: First, at least some amodal completion-involved experiences can ground knowledge about the occluded portions of perceived objects. Second, at least some instances of amodal completion-grounded knowledge are not sensitive, that is, it is not the case that in the nearest worlds in which the relevant claim is false, that claim is not believed true. Third, at least some instances of (...) amodal completion-grounded knowledge are not safe, that is, it is not the case that in all or nearly all near worlds where the relevant claim is believed true, that claim is in fact true. Thus, certain instances of amodal completion-grounded knowledge refute both the view that knowledge is necessarily sensitive and the view that knowledge is necessarily safe. (shrink)

When we see an object, we also represent those parts of it that are not visible. The question is how we represent them: this is the problem of amodal perception. I will consider three possible accounts: (a) we see them, (b) we have non-perceptual beliefs about them and (c) we have immediate perceptual access to them, and point out that all of these views face both empirical and conceptual objections. I suggest and defend a fourth account, according to which (...) we represent the occluded parts of perceived objects by means of mental imagery. This conclusion could be thought of as a (weak) version of the Strawsonian dictum, according to which “imagination is a necessary ingredient of perception itself”. (shrink)

Summary Amodal completion involves the impression of existence and properties of visually occluded parts of objects. One aspect of this phenomenon that has been somewhat neglected is the amodal completion of color, which involves the impression that amodally completed surfaces have a particular color. In this paper, this aspect is investigated by constructing a large number of displays with identical target figures embedded in systematically varying contexts, to find out which contexts are conducive for amodal completion of (...) color and which are not. In this setup, the main effects of changes of contexts are changes of geometric and photometric features of junctions along the borders of the target regions, which can cause dramatic differences in the appearance of those regions. Generally, a certain arrangement of T-junctions supports the impression of amodal completion of color, and it can be argued that certain types of X-junctions support a variant of this effect as well.

Defenders of The Pure View – “Purists”, as I shall call them – maintain that perception is pure presentation. That is, a perceptual experience has no commitments that exceed what is given or presented in the experience. I argue The Pure View seems unable to offer a convincing account of amodal completion. I distinguish three Purist strategies for addressing amodal completion, and suggest that none is very promising.

In a recent paper, Helton and Nanay, 415–423, 2019) present a new argument against two modal accounts of knowledge—safety and sensitivity. Their argument is based on the phenomenon of amodal completion. According to them, amodal completion experience can ground knowledge; but in some instances, such knowledge is neither sensitive nor safe. Thus, they conclude that neither sensitivity nor safety is a necessary condition for knowledge. This paper pushes back. In particular, I defend the following three theses. First, Helton (...) and Nanay’s argument for the claim that amodal completion itself can ground knowledge is unsound. Second, their objection against sensitivity is best construed as merely another instantiation of the old objection against sensitivity regarding inductive knowledge. Thus, sensitivity theorists have nothing to worry about over and above the old objection. Third, safety theorists can plausibly defend their account, insofar as they acknowledge that one’s ‘awareness’ of error-possibilities can affect the epistemic status of one’s belief. My conclusion is that reflections on the phenomenon of amodal completion fail to generate any new objections against modal accounts of knowledge. (shrink)

Although Barsalou is right in identifying the importance of perceptual symbols as a means of carrying certain kinds of content, he is wrong in playing down the inferential resources available to amodal symbols. I argue that the case for perceptual symbol systems amounts to a false dichotomy and that it is feasible to help oneself to both kinds of content as extreme ends on a content continuum. The continuum thesis I advance argues for the inferential content at one end (...) and perceptual content at the other. In between the extremes, symbols might have aspects that are either perceptual or propositional-linguistic in character. I argue that this way of characterising the issue preserves the good sense of Barsalou's recognition of perceptual representations and yet avoids the tendency to minimise the gains won with symbolic representations vital to contemporary cognitive science.

Inspired by Rick Grush's emulation theory, we reinterpreted a series of our neuroimaging experiments which were intended to examine the representations of complex movement, modality-specific imagery, and supramodal imagery. The emulation theory can explain motor and cognitive activities observed in cortical motor areas, through the speculation that caudal areas relate to motor-specific imagery and rostral areas embrace an emulator for amodal imagery.

The debate about the nature of the representational format of concepts seems to have reached an impasse. The debate faces two fundamental problems. Firstly, amodalists (i.e., those who argue that concepts are represented by amodal symbols) and modalists (i.e., those who see concepts as involving crucially representations including sensorimotor information) claim that the same empirical evidence is compatible with their views. Secondly, there is no shared understanding of what a modal or amodal format amounts to. Both camps recognize (...) that the two formats play essential roles in higher cognition, leading to an increasing number of hybrid proposals. In this paper, I argue that the existence of those fundamental problems should make us suspicious about a modal/amodal dichotomy. Also, I suggest that hybrid approaches, as they currently stand, do not provide suitable solutions to the impasse. Instead, we should overcome the dichotomy and treat the modal/amodal distinction as a graded phenomenon. I illustrate this hypothesis with an example of a cognitive-computational model of concepts based on the Predictive Processing framework. (shrink)

The problem of amodal perception is the problem of how we represent features of perceived objects that are occluded or otherwise hidden from us. Bence Nanay (2010) has recently proposed that we amodally perceive an object's occluded features by imaginatively projecting them into the relevant regions of visual egocentric space. In this paper, I argue that amodal perception is not a single, unitary capacity. Drawing appropriate distinctions reveals amodal perception to be characterized not only by mental imagery, (...) as Nanay suggests, but also by genuinely visual representations as well as beliefs. I conclude with some brief remarks on the role of object-directed bodily action in conferring a sense of unseen presence on an object's occluded features. (shrink)

We are aware of those parts of a cat that are occluded behind a fence. The question is how we represent these occluded parts of perceived objects: this is the problem of amodal perception. I will consider four theories and compare their explanatory power: (i) we see them, (ii) we have nonperceptual beliefs about them, (iii) we have immediate perceptual access to them and (iv) we visualize them. I point out that the first three of these views face both (...) empirical and conceptual objections. I argue for the fourth account, according to which we visualize the occluded parts of perceived objects. Finally, I consider some important consequences of this view with regards to the content and the evolution of visualization. (shrink)

Barsalou has recently argued against the strategy of identifying amodal neural representations by using their cross-modal responses (i.e., their responses to stimuli from different modalities). I agree that there are indeed modal structures that satisfy this “cross-modal response” criterion (CM), such as distributed and conjunctive modal representations. However, I argue that we can distinguish between modal and amodal structures by looking into differences in their cross-modal responses. A component of a distributed cell assembly can be considered unimodal because (...) its responses to stimuli from a given modality are stable, whereas its responses to stimuli from any other modality are not (i.e., these are lost within a short time, plausibly as a result of cell assembly dynamics). In turn, conjunctive modal representations, such as superior colliculus cells in charge of sensory integration, are multimodal because they have a stable response to stimuli from different modalities. Finally, some prefrontal cells constitute amodal representations because they exhibit what has been called ‘adaptive coding’. This implies that their responses to stimuli from any given modality can be lost when the context and task conditions are modified. We cannot assign them a modality because they have no stable relation with any input type. (shrink)

Oblak, Boyadzhieva, and Bon claim that fractality is a modal property of the experience of perceptual presence. I will instead argue that the concept of fractality implies amodality and that modal ….

Barsalou's interesting model might benefit from defining simulation and clarifying the implications of prior critiques for simulations (and not just for perceptual symbols). Contrary to claims, simulators (or frames) appear, in the limit, to be amodal. In addition, the account of abstract terms seems extremely limited.

It has been argued that the approximate number system (ANS) constitutes a problem for the grounded approach to cognition because it implies that some conceptual tasks are performed by non-perceptual systems. The ANS is considered non-perceptual mainly because it processes stimuli from different modalities. Jones (2015) has recently argued that this system has many features (such as being modular) which are characteristic of sensory systems. Additionally, he affirms that traditional sensory systems also process inputs from different modalities. This suggests that (...) the ANS is a perceptual system and therefore it is not problematic for the grounded view. In this paper, I defend the amodal approach to the ANS against these two arguments. In the first place, perceptual systems do not possess the properties attributed to the ANS and therefore these properties do not imply that the ANS is perceptual. In the second place, I will propose that a sensory system only needs to be dedicated to process modality-specific information, which is consistent with responding to inputs from different modalities. I argue that the cross-modal responses exhibited by traditional sensory systems are consistent with modality-specific information whereas some responses exhibited by the ANS are not. (shrink)

James Gibson's theory of information, as specific to (but not necessarily ) its sources, is especially indebted to the study of occlusion for its core examples. In occlusion, one is aware of hidden surfaces. Is this still too related to one modality to count as a good case for Stoffregen & Bardy?

Event sequences or scripts are the conceptual representations of activities in memory. Traditional views hold that events are represented in amodal networks and are retrieved by associative strategies. The embodied cognition approach holds that knowledge is grounded in perception and retrieved by mental simulation. We used a script generation task where event sequences of activities had to be produced. Activities varied in their degree of familiarity. In a regressional design we investigated whether amodal or perceptual variables best predicted (...) knowledge retrieval to gain insight into the underlying representation. Retrieval depended on the familiarity of the activity. While novel activities mainly relied on perception‐based simulation and to a lesser extent on associative strategies, moderately familiar activities showed the opposite pattern, and events of familiar activities were retrieved by association alone. We conclude that amodal structures exist in all representations that become stronger with increasing frequency and finally prevail over perceptual structures. (shrink)

In this paper, I examine our intuitive understanding of metaphysical contingency, and ask what features a metaphysical picture must possess in order to satisfy our intuitions about modal matters. After spelling out what I think are the central intuitions in this domain, I examine the debate between the two most widely held views on the nature of modality, namely, modal realism and modal actualism. I argue that while each of these views is able to accommodate some of our intuitions, it (...) leaves others unsatisfied. I then present an alternative metaphysical picture, which I argue can accommodate our intuitions in a way that the traditional views cannot. More specifically, I argue that our intuitions about modality call for a pluralist view of the structure of reality—a view on which there is more than one ultimate ‘shape’ to the fundamental facts, each corresponding to a distinct metaphysically privileged perspective on reality.

Amodality is not incompatible with being originally derived from sensory experience. The transformation of perceptual symbols into amodal abstractions could take place spontaneously through self-organizing processes such as autocatalysis. The organizational role played by “simulators” happens implicitly in a neural network, and quite possibly, in the brain as well.

Comparisons between modally and amodally completed regions show that perceptual filling-in is not merely the ignoring of absences. Illusory filled-in colour arises for modal completion, but not for amodal completion in comparable displays. We find that attention spreads automatically to modally but not amodally completed regions from their inducers, revealing a functional effect of filled-in colour.

In this study, we analyzed the relationship between the amodal (semantic) development of words and two popular emotional norms (emotional valence and arousal) in English and Spanish languages. To do so, we combined the strengths of semantics from vector space models (vector length, semantic diversity, and word maturity measures), and feature-based models of emotions. First, we generated a common vector space representing the meaning of words at different developmental stages (five and four developmental stages for English and Spanish, respectively) (...) using the Word Maturity methodology to align different vector spaces. Second, we analyzed the amodal development of words through mixed-effects models with crossed random effects for words and variables using a continuous time metric. Third, the emotional norms were included as covariates in the statistical models. We evaluated more than 23,000 words, whose emotional norms were available for more than 10,000 words, in each language separately. Results showed a curve of amodal development with an increasing linear effect and a small quadratic deceleration. A relevant influence on the amodal development of words was found only for emotional valence (not for arousal), suggesting that positive words have an earlier amodal development and a less pronounced semantic change across early lifespan.

'Concept' is a central notion in modern philosophy. This book deals with the philosopher Aristotle to compare modern theories of 'concepts' as he is said to be the predecessor both of classical theory and of modal theories of 'concepts' in the modern debate. Both pathêma and logos are central to his theory of language, thought, and concepts.

A recent study published in Nature Neuroscience purports to have answered a question posed to Locke in 1688 by his friend William Molyneux, namely, whether ‘a man born blind and made to see’ would be able to identify, immediately and by vision alone, objects previously known only by touch. The answer, according to the researchers – and as predicted by Molyneux, as well as Locke, Berkeley, and others – is ‘likely negative. The newly sighted subjects did not exhibit an immediate (...) transfer of their tactile shape knowledge to the visual domain’. Since then, however, many commentators have argued that the answer is still not clear. Moreover, in the contemporary literature on Molyneux’s Question, and more generally on cross-modal perception and the individuation of the senses, it is sometimes hard to determine what question is being investigated. In this paper, I distinguish a number of different questions about the relation between visual and tactual perception that can arise when considering Molyneux’s... (shrink)

Previous research showed that sensorimotor information affects the perception of properties associated with implied perceptual context during language comprehension. Three experiments addressed a novel question of whether perceptual context may contribute to a simulation of information about such out‐of‐sight objects as cast shadows. In Experiment 1, participants read a sentence that implied a particular shadow cast on a target (blinds vs. an open window) and then verified the picture of the object onto which a shadow was cast. Responses were faster (...) when the shadow of blinds cast on the object matched that implied by the sentence. However, the data did not show the same matching effect for pictures with cast shadows from an open window. In Experiments 2 and 3, we found that verification times for pictures with no cast shadows were faster when preceded by an “open window” sentence, thus suggesting that reading the sentence does not elicit a visual simulation of any specific shadow. Experiment 3 showed that the objects superimposed with a cast shadow of the blinds and blinds themselves were verified faster after reading a “blinds” sentence. However, the results of an order analysis showed the temporal stability of the “blinds shadows” effect, but the disappearance of the “blinds” effect in the second half of the data. We conclude that the results are compatible, to a lesser or greater extent, with multiple accounts, and discuss our findings in the context of a mental imagery view, a mental simulation view, and an amodal representation view.
