We describe the three place relation of contrastive knowledge, which holds between a person, a target proposition, and a contrasting proposition. The person knows that p rather than that q. We argue for three claims about this relation. (a) Many common sense and philosophical ascriptions of knowledge can be understood in terms of it. (b) Its application is subject to fewer complications than non-contrastive knowledge is. (c) It applies over a wide range of human and nonhuman cases.

According to proponents of irreducible cognitive phenomenology some cognitive states put one in phenomenal states for which no wholly sensory states suffice. One of the main approaches to defending the view that there is irreducible cognitive phenomenology is to give a phenomenal contrast argument. In this paper I distinguish three kinds of phenomenal contrast argument: what I call pure—represented by Strawson's Jack/Jacques argument—hypothetical—represented by Kriegel's Zoe argument—and glossed—first developed here. I argue that pure and hypothetical phenomenal contrast arguments face significant (...) difficulties, but that there is a sound glossed phenomenal contrast argument for irreducible cognitive phenomenology.

If counterfactual dependence is sufficient for causation and if omissions can be causes, then all events have many more causes than common sense tends to recognize. This problem is standardly addressed by appeal to pragmatics. However, Carolina Sartorio [2010] has recently raised what I shall argue is a more interesting problem concerning omissions for counterfactual theories of causation—more interesting because it demands a more subtle pragmatic solution. I discuss the relationship between the idea that causes are proportional to their effects, (...) the idea that causation is contrastive, and the question of the dimensions along which causal explanations should be evaluated with respect to one another.

In this paper, I draw on a recent account of perceptual knowledge according to which knowledge is contrastive. I extend the contrastive account of perceptual knowledge to yield a contrastive account of self-knowledge. Along the way, I develop a contrastive account of the propositional attitudes (beliefs, desires, regrets and so on) and suggest that a contrastive account of the propositional attitudes implies an anti-individualist account of propositional attitude concepts (the concepts of belief, desire, regret, and (...) so on). (shrink)

We give a general description of a class of contrastive constructions, intended to capture what is common to contrastive knowledge, belief, hope, fear, understanding and other cases where one expresses a propositional attitude in terms of “rather than”. The crucial element is the agent's incapacity to distinguish some possibilities from others. Contrastivity requires a course-graining of the set of possible worlds. As a result, contrastivity will usually cut across logical consequence, so that an agent can have an attitude (...) to p rather than q but not to r rather than q , where r is a logical consequence of p . We relate these ideas to some general issues about thought, such as the question of whether all possibilities that can be distinguished in emotion can be distinguished in belief. (shrink)

In some philosophical arguments an important role is played by the claim that certain situations differ from each other with respect to phenomenology. One class of such arguments are minimal pair arguments. These have been used to argue that there is cognitive phenomenology, that high-level properties are represented in perceptual experience, that understanding has phenomenology, and more. I argue that facts about our mental lives systematically block such arguments, reply to a range of objections, and apply my critique to some (...) examples from the literature. (shrink)

A promising but underexplored view about normative reasons is contrastivism, which holds that considerations are fundamentally reasons for things only relative to sets of alternatives. Contrastivism gains an advantage over non-contrastive theories by holding that reasons relative to different sets of alternatives can be independent of one another. But this feature also raises a serious problem: we need some way of constraining this independence. I develop a version of contrastivism that provides the needed constraints, and that is independently motivated (...) by the widespread idea that reasons involve the promotion of various kinds of objectives.

Phenomenal contrast arguments (PCAs) are normally employed as arguments showing that a certain mental feature contributes to (the phenomenal character of) experience, that certain contents are represented in experience and that kinds of sui generis phenomenologies such as cognitive phenomenology exist. In this paper we examine a neglected aspect of such arguments, i.e., the kind of mental episodes involved in them, and argue that this happens to be a crucial feature of the arguments. We use linguistic tools to determine the (...) lexical aspect of verbs and verb phrases – the tests for a/telicity and for duration. We then suggest that all PCAs can show is the presence of a generic achievement-like phenomenology, especially in the cognitive domain, which contrasts with the role that PCAs are given in the literature.

Carl Hempel (1965) argued that probabilistic hypotheses are limited in what they can explain. He contended that a hypothesis cannot explain why E is true if the hypothesis says that E has a probability less than 0.5. Wesley Salmon (1971, 1984, 1990, 1998) and Richard Jeffrey (1969) argued to the contrary, contending that P can explain why E is true even when P says that E’s probability is very low. This debate concerned noncontrastive explananda. Here, a view of contrastive (...) causal explanation is described and defended. It provides a new limit on what probabilistic hypotheses can explain; the limitation is that P cannot explain why E is true rather than A if P assign E a probability that is less than or equal to the probability that P assigns to A. The view entails that a true deterministic theory and a true probabilistic theory that apply to the same explanandum partition are such that the deterministic theory explains all the true contrastive propositions constructable from that partition, whereas the probabilistic theory often fails to do so.

How do philosophers of science make use of historical case studies? Are their accounts of historical cases purpose-built and lacking in evidential strength as a result of putting forth and discussing philosophical positions? We will study these questions through the examination of three different philosophical case studies. All of them focus on modeling and on Vito Volterra, contrasting his work to that of other theoreticians. We argue that the worries concerning the evidential role of historical case studies in philosophy are (...) partially unfounded, and the evidential and hermeneutical roles of case studies need not be played against each other. In philosophy of science, case studies are often tied to conceptual and theoretical analysis and development, rendering their evidential and theoretic/hermeneutic roles intertwined. Moreover, the problems of resituating or generalizing local knowledge are not specific to philosophy of science but commonplace in many scientific practices—which show similarities to the actual use of historical case studies by philosophers of science.

Consider three cases: -/- Turn: A trolley is about to kill five innocent strangers. You can turn the trolley onto me, saving the five and killing me. -/- Hurl: A trolley is about to kill five innocent strangers. You can hurl me at the trolley, saving the five and paralyzing me. -/- TurnHurl: A trolley is about to kill five innocent strangers. You can turn the trolley onto me, saving the five and killing me. You can instead hurl me at (...) the trolley, saving the five and paralyzing me. -/- Most find the following four claims intuitively plausible: -/- (1) It is permissible to turn the trolley onto me in Turn. (2) It is impermissible to hurl me at the trolley in Hurl. (3) It is impermissible to turn the trolley onto me in TurnHurl. (4) It is permissible to hurl me at the trolley in TurnHurl. -/- But how does turning go from permissible to impermissible, and hurling from impermissible to permissible, when both alternatives are available? I argue that such “secondary permissibility” claims are explained by contrastive consent. Even if I do not consent to being harmed, it is likely I’ll consent to being hurled at the trolley rather than being turned onto. (shrink)

In psychophysical experiments, the use of a psychophysical procedure of brightness/darkness cancellation shed light on interactions between spatial arrangement and figure–ground contrast in the perceptual filling in of achromatic and colored surfaces.Achromatic and chromatic Kanizsa squares with varying contrast, contrast polarity, and inducer spacingwere used to test how these factors interact in the perceptual filling in of surface brightness or darkness. The results suggest that the neuronal processing of surfaces with apparent contrast, leading to figure–ground segregation (i.e., perceptual organization), is (...) governed by mechanisms that integrate both luminance contrast and spatial information carried by the inducing stimuli, while discarding information on contrast polarity or color. The findings are discussed in relation to earlier observations on brightness assimilation and contrast. They support theories of nonantagonistic neural mechanisms suppressing local contrast or color signs in brightnessbased figure–ground percepts. Such mechanismsmight be necessary to cancel potentially conflicting polarities in geometricallycomplex visual stimuli so that perceptual filling in resulting in the most plausible representation of figure and ground can be achieved.

Aristotle contrasts episteme and doxa through the key notions of universal and necessary. These notions have played a central role in Aristotle’s characterization of scientific knowledge in the previous chapters of APo. They are not spelled out in APo I.33, but work as a sort of reminder that packs an adequate characterization of scientific knowledge and thereby gives a highly specified context for Aristotle’s contrast between episteme and doxa. I will try to show that this context introduces a contrast in (...) terms of explanatory claims: on the one hand, episteme covers those claims which capture explanatory connections that are universal and necessary and thereby deliver scientific understanding; on the other hand, doxa covers the explanatory attempts that fail at doing so.

Suppose that Ann says, “Keith knows that the bank will be open tomorrow.” Her audience may well agree. Her knowledge ascription may seem true. But now suppose that Ben—in a different context—also says “Keith knows that the bank will be open tomorrow.” His audience may well disagree. His knowledge ascription may seem false. Indeed, a number of philosophers have claimed that people’s intuitions about knowledge ascriptions are context sensitive, in the sense that the very same knowledge ascription can seem true (...) in one conversational context but false in another. This purported fact about people’s intuitions serves as one of the main pieces of evidence for epistemic contextualism. (shrink)

According to Sparse views of perceptual content, the phenomenal character of perceptual experience is exhausted by the experiential presentation of ‘low-level’ properties such as (in the case of vision) shapes, colors, and textures Whereas, according to Rich views of perceptual content, the phenomenal character of perceptual experience can also sometimes involve experiencing ‘high-level’ properties such as natural kinds, artefactual kinds, causal relations, linguistic meanings, and moral properties. An important dialectical tool in the debate between Rich and Sparse theorists is the (...) so-called ‘method of phenomenal contrast’. I explore how this method of phenomenal contrast interacts with the sort of content-externalism made familiar by Putnam. I show that the possibility of Twin Earth style cases places important restrictions on the range of properties that the method of phenomenal contrast could plausibly apply to. Moreover, these restrictions would apply to some paradigmatically low-level properties as well as to some of the frequently advanced high-level properties. I also draw some general lessons about the different ways one might conceive of the relation between phenomenal character and representational content. (shrink)

This chapter examines when and how mental simulation--the consideration of alternatives to present reality--produces emotional responses that reflect either contrast or assimilation. The chapter begins with a description of a comparison domain that is most commonly associated with mental simulation--counterfactual thinking. Then the authors consider how mental simulation plays a critical role in determining assimilative and contrastive responses to other type of comparisons. The chapter concludes with a presentation of a model of mental simulation-based comparison processes and describe its (...) relationship to other contemporary comparison models. (shrink)

The article aims at contrasting the autopoietic understanding of an individual and her or his actions as described by Niklas Luhmann with Paul Ricoeur’s notion of narrative identity, focusing on people as legal subjects. The article assumes that when legal subjects necessitate ethical engagement and evaluation, the law could cease to deal with problems in a mere legalistic fashion but is allowed the freedom to appeal to norms of justice external to itself as in other natural law theories. Through narrative (...) identity the deeds of role players are to be understood in greater complexity than what a self-referential legal system is comfortable in dealing with. (shrink)

The problem of mental causation is discussed by taking into account some recent developments in the philosophy of science. The problem is viewed from the perspective of the new interventionist theory of causation developed by Woodward. The import of the idea that causal claims involve contrastive classes in mental causation is also discussed. It is argued that mental causation is much less a problem than it has appeared to be.

This thesis is a defense of (a version of) moral perceptualism. Moral perceptualism (MP), as is generally understood, advocates the bold view that “moral properties can be perceptual content”; its supporters include Audi (2013, 2015), Lord (2018), McNaughton (1988), McBrayer (2010a, 2010b), Cowan (2015), and Werner (2016, 2020b). In support of MP, Werner (2016) bolsters what he calls ‘phenomenal contrast arguments(PCAs)’. According to PCAs, the best explanation for inter-subjective phenomenal contrast between two subjects facing the same moral situation is that (...) one subject has moral perceptual experience(s) of moral properties, whereas the other does not. If PCAs are sound, then MP can be justified (in that one subject does perceive moral properties). However, some powerful counterarguments against MP have been proposed by Väyrynen(2018), Reiland(2021), and Chudnoff(2015); each of them provides competing explanations for inter-subjective phenomenal contrast and argues that their explanations are more reasonable than PCAs. My purposes in this thesis are to ascertain (I) which explanation for inter-subjective phenomenal contrast is more reasonable; (II) (how) could moral perceptualists like Werner (2016, 2020b) properly reply to the counterarguments against MP？ Or is there any better alternative explanation that could support MP？ As regards (I), I will argue that Väyrynen’s(2018), Reiland’s(2021), and Chudnoff's (2015) alternative explanatory models for inter-subjective phenomenal contrast are not to be seen as competing explanations against the one provided by MP; rather, they are complementary to it. As regards (II), I argue that Väyrynen’s(2018), Reiland’s(2021), and Chudnoff's (2015) conterarguments against MP at most demonstrate that certain moral properties (e.g., rightness/ wrongness/goodness/badness) can’t be part of the perceptual content, but their arguments do not (or indeed cannot) rule out the possibility that moral salience can be properly construed as part of the perceptual content. In light of this, I argue that an alternative version of moral perceptualism, or what I call ‘moral salience perceptualism’, according to which “moral salience can be part of the perceptual content”, still remains alive and kicking in face of their counteraguments. Moreover, I argue that moral salience perceptualism is explanatorily superior to Werner’s (2016) version of MP in terms of explaining inter-subjective phenomenal contrast. -/- Keywords： moral perceptualism, phenomenal contrast, moral salience, moral experiences, moral judgments -/- .

The method of phenomenal contrast (in perception) invokes the phenomenal character of perceptual experience as a means to discover its contents. The method implicitly takes for granted that ‘what it is like’ to have a perceptual experience e is the same as ‘what it is like’ to imagine or recall it; accordingly, in its various proposed implementations, the method treats imaginations and/or recollections as interchangeable with real experiences. The method thus always contrasts a pair of experiences, at least one of (...) which is imagined or remembered rather than occurrent. Surveying all eighteen forms of implementing the method, I argue that in all of the proposed pairings, the substitution of imagination or recollection for perceptual experience in the method, is either inconceivable or impermissible. I identify four reasons why I think imagination cannot be substituted for real experience, and three reasons why recollection cannot be substituted for real experience. If my argument works, there is no form of implementing the method that is useful for discovering the contents of experience, and thus the method is not a well‐functioning tool to study the contents of perception.

Commentary of Justin Garson, "Madness and idiocy: Reframing a basic problem of philosophy of psychiatry." Philosophy, Psychiatry, & Psychology.

Consciousness still remains puzzling and controversial. This paper demonstrates that at general and objective level, for understanding consciousness it is necessary to understand such fundamental concepts as contrast, interaction, complexity and emergence. New definitions of these terms are provided as they are erroneous or incomplete in their current form. The result of these investigations is the explanation that consciousness is the sensation of energy interaction (like the sensation of touch or pain), but in a more complex form. This objective explanation (...) and the resulting conclusions have been applied to the study of artificial intelligence consciousness and creativity. Specific solutions have been proposed here.

This paper introduces and argues for contrastivism about intentions. According to contrastivism, intention is not a binary relation between an agent and an action. Rather, it is a ternary relation between an agent, an action, and an alternative. Contrastivism is introduced via a discussion of cases of known but (apparently) unintended side effects. Such cases are puzzling. They put pressure on us to reject a number of highly compelling theses about intention, intentional action, and practical reason. And they give rise (...) to a puzzle about rather than constructions such as ‘I intend to φ rather than ψ’: In side effect cases it can seem wrong to claim that the subject intends to φ, yet acceptable to claim that they intend to φ rather than ψ. This cries out for explanation. Contrastivism provides a unified response to all of these problems. (shrink)

Contrastivists view ought-sentences as expressing comparisons among alternatives. Deontic actualists believe that the value of each alternative in such a comparison is determined by what would actually happen if that alternative were to be the case. One of the arguments that motivates actualism is a challenge to the principle of agglomeration over conjunction—the principle according to which if you ought to run and you ought to jump, then you ought to run and jump. I argue that there is no way (...) of developing the actualist insight into a logic that invalidates the agglomeration principle without also invalidating other desirable patterns of inference. After doing this, I extend the analysis to other contrastive views that challenge agglomeration in the way that the actualist does. This motivates skepticism about the actualist’s way of challenging agglomeration. (shrink)

The method of contrast is used within philosophy of perception in order to demonstrate that a specific property could be part of our perception. The method is based on two passages. I argue that the method succeeds in its task only if the intuition of the difference, which constitutes the core of the first passage, has two specific traits. The second passage of the method consists in the evaluation of the available explanations of this difference. Among the three outlined options, (...) I will demonstrate that only in the third option – as we shall see, the case of the scenario that remains the same but is perceived in two different ways by the same perceiver – the intuition purports a difference that posses the necessary characteristics, namely being immediately evident and extremely complex and multifaceted, which determine its tensive nature. The application within auditory perception of this third option will generate two cases, a diachronic one and a synchronic one, which clearly show that we can auditorily perceive causality as a link between two sonorous episodes. The causal explanation is the only possible explanation among the many evaluated within the second passage of the method of contrast. (shrink)

This paper argues for contrastivism about the deontic modals, 'ought', 'must', and 'may'. A simple contrastivist semantics that predicts the desired entailment relations among these modals is offered.

Mathematical models provide explanations of limited power of specific aspects of phenomena. One way of articulating their limits here, without denying their essential powers, is in terms of contrastive explanation.

What is required for an action to promote the satisfaction of a desire? We reject extant answers and propose an alternative. Our account differs from competing answers in two ways: first, it is contrastive, in that actions promote the satisfaction of desires only as contrasted with other possible actions. Second, it employs a notion of expected fit between desire and world, defined as the weighted sum of the fit between the desire and the world in all possible outcomes, where (...) each weight is given by the probability of the agent’s obtaining the relevant outcome. According to our proposal, then, an action promotes a desire when the expected fit for the desire given that the agent performs the action is greater than the expected fit of the desire given that the agent performs the contrasting action. We highlight this account’s attractive features and explain how it improves on its competitors. (shrink)

Poorly saturated colors are closer to a pure grey than strongly saturated ones and, therefore, appear less “colorful”. Color saturation is effectively manipulated in the visual arts for balancing conflicting sensations and moods and for inducing the perception of relative distance in the pictorial plane. While perceptual science has proven quite clearly that the luminance contrast of any hue acts as a self-sufficient cue to relative depth in visual images, the role of color saturation in such figure-ground organization has remained (...) unclear. We presented configurations of colored inducers on grey ‘test’ backgrounds to human observers. Luminance and saturation of the inducers was uniform on each trial, but varied across trials. We ran two separate experimental tasks. In the relative background brightness task, perceptual judgments indicated whether the apparent brightness of the grey test background contrasted with, assimilated to, or appeared equal (no effect) to that of a comparison background with the same luminance contrast. Contrast polarity and its interaction with color saturation affected response proportions for contrast, assimilation and no effect. In the figure-ground task, perceptual judgments indicated whether the inducers appeared to lie in front of, behind, or in the same depth with the background. Strongly saturated inducers produced significantly larger proportions of foreground effects indicating that these inducers stand out as figure against the background. Weakly saturated inducers produced significantly larger proportions of background effects, indicating that these inducers are perceived as lying behind the backgrounds. We infer that color saturation modulates figure-ground organization, both directly by determining relative inducer depth, and indirectly, and in interaction with contrast polarity, by affecting apparent background brightness. The results point towards a hitherto undocumented functional role of color saturation in the genesis of form, and in particular figure-ground percepts in the absence of chromatostereopsis. (shrink)

The conventional implicature, arguably, refers to plenty of linguistic aspects with respect to episteme, metaphysics, as well as semantic criticism of language. Accordingly, the conventional implication consists of a sort of specific literal meanings, which slightly differ from the conversational implication. In addition to that, the particular taxonomy of slur words intends to utter a variety of dyslogistic, disparaging expressions in terms of bad or awful contents along with immoral conducts of a word. Hence, it is, apparently, debatable and doubtful (...) that to what extent slur words can convey unethical substance in a way of the conventional implicature? This contrastive article, therefore, attempts to examine credible reasons for clarifying the thesis: the awful essence of pejorative words comes with a conventional implicature. Correspondingly, I have emphasised a few substantial findings such as combinatorial externalism, prohibitionism alongside expressivism. However, notwithstanding this semantic analysis, it is restricted to investigate epistemic and metaphysical affiliations in this regard. (shrink)

Can an identity be the proper subject of an explanation? A popular stance, albeit not one often argued for, gives a negative answer to this question. Building from a contentious passage from Jaegwon Kim in this direction, we reconstruct an argument to the conclusion that identities, to the extent in which they are necessary, cannot be explained. The notion of contrastive explanation, characterized as difference-seeking, will be crucial for this argument; however, we will eventually find the argument to be (...) unsatisfactory. On the contrary, the discussion provides enough resource to sketch a very simple framework for a non-causal contrastive explanation of identities. Many instances will be provided, with different varieties of explanans, ultimately suggesting that certain entailment or biconditional principles involving identities (first and foremost, so-called two-level identity criteria) may indeed be taken to have an inherent explanatory value.

Intrapersonal variation due to color contrast effects has been used to argue against the following intuitive propositions about the colors: No object can be more than one determinable or determinate color of the same grade all over at the same time ; external objects are actually colored ; and the colors of objects are mind-independent. In this article, I provide a defense of Incompatibility, Realism, and Objectivism from intrapersonal variation arguments that rely on color contrast effects. I provide a novel, (...) ecumenical response to such arguments according to which typical variants are right, and which respects Incompatibility, Realism, and Objectivism, using the thesis that the colors of objects depend on the colors of objects in their surrounds.

The book Theory and Practice of Contrast completes, corrects and integrates the foundations of science and humanities, which include: theory of art, philosophy (aesthetics, epistemology, ontology, axiology), cognitive science, theory of information, theory of complexity and physics. Through the integration of these distant disciplines, many unresolved issues in contemporary science have been clarified or better understood, among others: defining impact (contrast) and using this definition in different fields of knowledge; understanding what beauty/art is and what our aesthetic preferences depend on; (...) deeper understanding of what complexity and information are in essence, and providing their general definitions. Complexity means integration, value and goodness - concepts that seem to be neglected today. The book also has a high degree of integration/complexity, although each chapter introduces a new issue. The last chapter: "Binary Model of the Universe" draws attention to the need for including in physics the analysis of our mind and the resulting new possibilities, which include the mentioned (digital) model of the universe. Despite the difficult issues raised here, this study is written in accessible language and may be interesting not only for scientists and academics. (shrink)

Dretske’s theory of self-knowledge is interesting but peculiar and can seem implausible. He denies that we can know by introspection that we have thoughts, feelings, and experiences. But he allows that we can know by introspection what we think, feel, and experience. We consider two puzzles. The first puzzle, PUZZLE 1, is interpretive. Is there a way of understanding Dretske’s theory on which the knowledge affirmed by its positive side is different than the knowledge denied by its negative side? The (...) second puzzle, PUZZLE 2, is substantive. Each of the following theses has some prima facie plausibility: there is introspective knowledge of thoughts, knowledge requires evidence, and there are no experiences of thoughts. It is unclear, though, that these claims form a consistent set. These puzzles are not unrelated. Dretske’s theory of self-knowledge is a potential solution to PUZZLE 2 in that Dretske’s theory is meant to show how,, and can all be true. We provide a solution to PUZZLE 1 by appeal to Dretske’s early work in the philosophy of language on contrastive focus. We then distinguish between “Closure” and “Transmissibility”, and raise and answer a worry to the effect that Dretske’s theory of self-knowledge runs counter to Transmissibility. These results help to secure Dretske’s theory as a viable solution to PUZZLE 2. (shrink)

Recent developments in our globalized world are beginning the scholarly world to answer the question pertaining to the relationship between Islam—a “faith”—and politics and governance. In order to understand the Islamic worldview from the perspective of Ibn Khaldun, with whom many modern Islamists would agree with, a comparison is made with early progenitors of liberalism and the social contract, John Locke and Thomas Hobbes. By understanding the fundamental differences between the theorists, and how Ibn Khaldun’s is completely separate from the (...) western tradition, it becomes easier to understand exactly why Islamic models of governance are at direct odds with the west. The main difference between the two models of governance is the use of a fundamental criteria determining right from wrong, as opposed to Hobbes’ and Locke’s theories being based purely on assumption that the validity of their respective arguments is based upon the theory’s acceptance among the people. In other words, western political theorists lack the consistency and justification for their theories, at least from the Islamist point of view. (shrink)

In this article I compare and, especially, contrast Aristotle’s conception of virtue with one typical of sub-Saharan philosophers. I point out that the latter is strictly other-regarding, and specifically communitarian, and contend that the former, while including such elements, also includes some self-regarding or individualist virtues, such as temperance and knowledge. I also argue that Aristotle’s conception of human excellence is more attractive than the sub-Saharan view as a complete account of how to live, but that the African conception is (...) a strong contender for a limited group of the most important virtues related to morality qua rightness.

In this paper, we attempt to de-naturalize the prevailing economistic imaginary of work that Max Weber and later commentators described as ‘protestant work ethic,’ epitomized in the figure of homo economicus. We do so by contrasting it with the imaginary of skillful work that can be found in vignettes about artisans in the Zhuangzi. We argue that there are interesting contrasts between these views concerning 1) direct goal achievement vs. indirect goal achievement through the cultivation of skills; 2) the hierarchization (...) of mental versus physical dimensions of work; 3) the crafting of non-dominating relationships between the working subject, their object, and their instruments of work, which leads to questions about the sustainability of these relationships; and 4) the relationship between work and well-being, which the Daoist texts conceptualize in a much more holistic, but also more presentist way than Western economic rationality. We conclude by pointing out the relevance of these differences for several contemporary debates about work, by denaturalizing a dominant imaginary of work, by distinguishing different forms of work, by suggesting a different relation between work and nature, and by raising questions about the desirability of the automation of work.

The article is based on an analysis of the works of the French historian Pierre Nora, who, trying to find a "true" history, comes to the opposition of history and memory. Outright political agitation and national imperatives are dominated in History, therefore history cannot be correct and objective. Instead of history, the philosopher believes, we should focus on the right memory. But when memory itself has been torn apart, it can only exist on the basis of "memory places" - mnemonic (...) places. The power of memory is preserved now in the places of memory that accumulate and preserve history. Places of memory have lost their physical or geographical meanings. Meaning and sense are made places of memory, important place for history. Due to the nature of the memory places, the multiplicities of their interpretations are the normal. And the past, therefore, became a poly semantic space, focused on the co-presence of many different versions of the interpretation of the same memorial structures (monuments, historical facts and events, texts of the past). Contrasting memory and history, P. Nora concludes about "the tyranny of memory (it is reminiscent of Reeker's statement). In his opinion, at any moment the memory is ready to lift history under itself, to "memorize" it, it deeply and dangerously distorts the meaning of words. Precisely because there is no collective memory, the places of memory appear that designed to compensate for its absence. When the space of memory disappears, mnemonic places appear. It is through mnemonic places (places of memory) as spaces that provide access to traditions, Nora moves from the present to the past. But the noble goal of finding the truth, of recreating traditions, has turned into honoring memory for political purposes, where the past has become the rhetorical construct of the present. Hence, the perception of truth is changing. Now, the truth is not in the "factuality" of the data, but in their "relevance". In the end, Nora makes a rather devastating conclusion for history- that the past has lost its meaning, the present historical consciousness gives meaning to all possible and valid versions of the past, and that official memory (politics of memory) is associated with practices of selective forgetting or memory.

This article explores some open questions related to the problem of verification of theories in the context of empirical sciences by contrasting three epistemological frameworks. Each of these epistemological frameworks is based on a corresponding central metaphor, namely: (a) Neo-empiricism and the gambling metaphor; (b) Popperian falsificationism and the scientific tribunal metaphor; (c) Cognitive constructivism and the object as eigen-solution metaphor. Each of one of these epistemological frameworks has also historically co-evolved with a certain statistical theory and method for testing (...) scientific hypotheses, respectively: (a) Decision theoretic Bayesian statistics and Bayes factors; (b) Frequentist statistics and p-values; (c) Constructive Bayesian statistics and e-values. This article examines with special care the Zero Probability Paradox (ZPP), related to the verification of sharp or precise hypotheses. Finally, this article makes some remarks on Lakatos’ view of mathematics as a quasi-empirical science. (shrink)

A new online social network service – Threads – was recently created and launched by Mark Zuckerberg to compete with Twitter. The rate at which people throughout the world accepted and created accounts on this new social network within hours of its creation and launching was prodigious. Conflicts have been inevitable in the world. As one of the Sustainable Development Goals of the United Nations (SDGs) (Goal 16) has to do with peaceful coexistence by the year 2030, this paper aims (...) at comparing the features of Twitter that can be used for conflict resolution to the emerging features of Threads. The paper gives the origin and acceptance of Threads. The discussion in the paper is based on the review of some selected literature, Public Sphere as a Theory of social media, an empirical review of a previous study, and comparisons of some features of Twitter with those of Threads. The paper concluded by giving a recommendation that while Twitter as a social network should not be jettisoned especially in resolving conflicts, the new social network – Threads – should be studied more to discover how it can be used better to resolve conflicts and promote peaceful coexistence in society thereby achieving Goal 16 of the SDGs by the year 2030.

The segregation of image parts into foreground and background is an important aspect of the neural computation of 3D scene perception. To achieve such segregation, the brain needs information about border ownership; that is, the belongingness of a contour to a specific surface represented in the image. This article presents psychophysical data derived from 3D percepts of figure and ground that were generated by presenting 2D images composed of spatially disjoint shapes that pointed inward or outward relative to the continuous (...) boundaries that they induced along their collinear edges. The shapes in some images had the same contrast (black or white) with respect to the background gray. Other images included opposite contrasts along each induced continuous boundary. Psychophysical results demonstrate conditions under which figure-ground judgment probabilities in response to these ambiguous displays are determined by the orientation of contrasts only, not by their relative contrasts, despite the fact that many border ownership cells in cortical area V2 respond to a preferred relative contrast. Studies are also reviewed in which both polarity-specific and polarity-invariant properties obtain perceptual figure-ground grouping results. The FACADE and 3D LAMINART models are used to explain these data. Keywords: figure-ground separation, border ownership, perceptual grouping, surface filling-in, V2, V4, FACADE Theory. (shrink)

The collective monograph "Ontology of Stative Situations - Linguistic Modeling. A Contrastive Bulgarian-Russian Study" includes research carried out within the project of the same name "Ontology of stative situations – linguistic modeling. A contrastive Bulgarian-Russian study", supported by the "Scientific Research" Fund of the Ministry of Education and Science in Bulgaria (№ КП-06-РУСИЯ / 23) and from the Russian Fund for Fundamental Research (No. 20-512-18005).

Contrastivism about interrogative understanding is the view that ‘S understands why p’ posits a three-place epistemic relation between a subject S, a fact p, and an alternative to p, q. This thesis stands in stark opposition to the natural idea that a subject S can be said to understand why psimpliciter. I argue that contrastivism offers the best explanation for the fact that evaluations of the form ‘S understands why p’ vary depending on the alternatives to p under consideration. I (...) also show that contrastivism offers valuable resources with which to explain the gradability of interrogative understanding attributions, as well as the sensitivity of these attributions to the perceived degree of epistemic demandingness of different contexts.

The quantization error in a fixed-size Self-Organizing Map (SOM) with unsupervised winner-take-all learning has previously been used successfully to detect, in minimal computation time, highly meaningful changes across images in medical time series and in time series of satellite images. Here, the functional properties of the quantization error in SOM are explored further to show that the metric is capable of reliably discriminating between the finest differences in local contrast intensities and contrast signs. While this capability of the QE is (...) akin to functional characteristics of a specific class of retinal ganglion cells (the so-called Y-cells) in the visual systems of the primate and the cat, the sensitivity of the QE surpasses the capacity limits of human visual detection. Here, the quantization error in the SOM is found to reliably signal changes in contrast or colour when contrast information is removed from or added to the image, but not when the amount and relative weight of contrast information is constant and only the local spatial position of contrast elements in the pattern changes. While the RGB Mean reflects coarser changes in colour or contrast well enough, the SOM-QE is shown to outperform the RGB Mean in the detection of single-pixel changes in images with up to five million pixels. This could have important implications in the context of unsupervised image learning and computational building block approaches to large sets of image data (big data). (shrink)

The perception of brightness differences in Ehrenstein figures and of illusory contours in phase-shifted line gratings was investigated as a function of the contrast polarity of the inducing elements. We presented either continuous lines or line-like arrangements composed of aligned dashes or dots whose spacing was varied. A yes/no procedure was used in which naive observers had to decide whether or not they perceived a brightness difference in a given Ehrenstein figure or an illusory contour in a phase-shifted line grating. (...) The results show that brightness differences are perceived to some extent in Ehrenstein figures with inducers of opposite polarity of contrast; however, the percentage of yes response was systematically lower and response times were longer than for figures with inducers of the same polarity. Phase-shifted line gratings with lines of opposite polarity of contrast yielded stronger illusory contours and shorter response times than those with lines of the same polarity. When the sign of contrast was not the same within a given line of induction, neither differences in brightness nor illusory contours were perceived. The results suggest that the mechanisms that lead to apparent differences in brightness are more sensitive to input of the same contrast polarity, the mechanisms generating illusory contours more sensitive to input of opposite polarity. The data are discussed in the light of a multistage approach to illusory form perception and some implications for cortical models of illusory contour integration are discussed. (shrink)

This article introduces an experimental paradigm to selectively probe the multiple levels of visual processing that influence the formation of object contours, perceptual boundaries, and illusory contours. The experiments test the assumption that, to integrate contour information across space and contrast sign, a spatially short-range filtering process that is sensitive to contrast polarity inputs to a spatially long-range grouping process that pools signals from opposite contrast polarities. The stimuli consisted of thin subthreshold lines, flashed upon gaps between collinear inducers which (...) potentially enable the formation of illusory contours. The subthreshold lines were composed of one or more segments with opposite contrast polarities. The polarity nearest to the inducers was varied to differentially excite the short-range filtering process. The experimental results are consistent with neurophysiological evidence for cortical mechanisms of contour processing and with the Boundary Contour System model, which identifies the short-range filtering process with cortical simple cells, and the long-range grouping process with cortical bipole cells.

In this paper we make a simple theoretical point using a practical issue as an example. The simple theoretical point is that robustness is not 'all or nothing': in asking whether a system is robust one has to ask 'robust with respect to what property?' and 'robust over what set of changes in the system?' The practical issue used to illustrate the point is an examination of degrees of linkage between sub-networks and a pointed contrast in robustness and fragility between (...) the dynamics of (1) contact infection and (2) information transfer or belief change. Time to infection across linked sub-networks, it turns out, is fairly robust with regard to the degree of linkage between them. Time to infection is fragile and sensitive, however, with regard to the type of sub-network involved: total, ring, small world, random, or scale-free. Aspects of robustness and fragility are reversed where it is belief updating with reinforcement rather than infection that is at issue. In information dynamics, the pattern of time to consensus is robust across changes in network type but remarkably fragile with respect to degree of linkage between sub-networks. These results have important implications for public health interventions in realistic social networks, particularly with an eye to ethnic and socio-economic sub-communities, and in social networks with sub-communities changing in structure or linkage.

Brincat and Westheimer [Journal of Neurophysiology 83 (2000) 1900] have reported facilitating interactions in the discrimination of spatially separated target orientations and co-linear inducing orientations by human observers. With smaller gaps between stimuli (short-range effects), facilitating interactions were found to depend on the contrast polarity of the stimuli. With larger gaps (longrange effects), only co-linearity of the stimuli seemed necessary to produce facilitation. In our study, the dependency of facilitating interactions on the intensity (luminance) of line stimuli is investigated by (...) measuring detection thresholds for a target line separated from the end of an inducing line by co-axial gaps ranging from 5 to 200 min of visual arc. We find facilitating interactions between target and inducing orientations, producing short-range and long-range effects similar to those reported by Brincat and Westheimer. In addition, detection thresholds as a function of the co-axial separation between target and inducing line reveal an interaction between the spatial regime of facilitating effects and the luminance of the stimuli. Short-range effects are found to be sensitive to changes in local intensity while long-range effects remain unaffected. (shrink)

This chapter looks for “continuity and convergence” between Davidson’s and Wittgenstein’s work, identifies common themes and family resemblances, as well as disagreements, especially in the theory of meaning. I take up in turn: -/- (1) their shared rejection of the utility of an ontology of meanings; (2) a convergence on the idea that we must show rather than say what an expression means; (3) the similarities and differences between them on meaning as use and the sense in which rule following (...) is essential for meaning; (4) the publicity of language, first in connection with radical interpretation; and (5) then with Davidson’s later work on triangulation in securing objective thought.

The replication crisis has caused researchers to distinguish between exact replications, which duplicate all aspects of a study that could potentially affect the results, and direct replications, which duplicate only those aspects of the study that are thought to be theoretically essential to reproduce the original effect. The replication crisis has also prompted researchers to think more carefully about the possibility of making Type I errors when rejecting null hypotheses. In this context, the present article considers the utility of two (...) types of Type I error probability: the Neyman–Pearson long run Type I error rate and the Fisherian sample-specific Type I error probability. It is argued that the Neyman–Pearson Type I error rate is inapplicable in social science because it refers to a long run of exact replications, and social science deals with irreversible units that make exact replications impossible. Instead, the Fisherian sample-specific Type I error probability is recommended as a more meaningful way to conceptualize false positive results in social science because it can be applied to each sample-specific decision about rejecting the same substantive null hypothesis in a series of direct replications. It is concluded that the replication crisis may be partly due to researchers’ unrealistic expectations about replicability based on their consideration of the Neyman–Pearson Type I error rate across a long run of exact replications.
