One way to enhance rule compliance is to provide people with arguments explaining why the desired behavior is important. We argue that there might be another, potentially more effective way to enhance rule compliance: ask people to generate arguments in favor of the rule themselves, which can trigger a process of self-persuasion. We compared the effects of providing arguments, asking respondents to generate arguments themselves, and a combination of both approaches on rule compliance and the perceived importance of the rule. (...) A field experiment revealed that rule compliance was higher in all experimental conditions compared to a control condition, with the highest level of rule compliance in the conditions that either presented the arguments or asked people to generate arguments themselves. Yet the rule was only evaluated as more important compared to the control condition, when people generated arguments themselves. This study suggests that rule compliance and perceived importance of this rule can be enhanced by easy low-cost interventions. (shrink)

Niemand dacht oorspronkelijker, speelser en scherper dan Ludwig Wittgenstein, en hij wist het. Van de kristallijnen helderheid in de 'Tractatus' tot de alledaagse onoverzichtelijkheid van de 'Filosofische onderzoekingen' blijft zijn denken één lange worsteling tegen de betovering van ons intellect door de schier eindeloze variatie van vermommingen waarin taal de gedachte aan het oog onttrekt.0Wittgenstein wist dat hij een bijzonder talent had, en zijn visie op zichzelf is zeker zo boeiend als zijn kijk op de wereld. In zijn brieven en (...) dagboeken treedt een geniale, lastige, komische en ontroerende man naar voren die in leven en in sterven een onuitwisbare indruk maakte op de mensen die hem kenden.0Bert Keizer biedt een heldere en toegankelijke introductie in leven en werk van Wittgenstein.

This paper tracks the development of Merleau-Ponty's inquiries into language through the themes of institution, symbolism, and nature in his Collège de France lectures of 1953-1960. It seeks to show the continuity of Merleau-Ponty's inquiries over this period. The Problem of Speech course (1953-1954) constitutes his last extended treatment of speech, language, and expression, and it leaves many questions unanswered. Nonetheless, a careful study of the course reveals that the inquiries that follow into institution and symbolism, and later into nature, (...) do not mark a sharp rupture with his earlier thought. Rather, the later investigations are required by those into language and expression to clarify the underlying functions that support them. Ultimately, the themes of language and nature will be deeply interwoven in Merleau-Ponty's late thought, with institution and symbolism serving as important mediating concepts. (shrink)

A formula ϕ in the one non-logical symbol ϵ with one free variable x is Russell if the sentence Vχ) is logically valid. This note describes a pattern common to the classical examples of Russell formulas, adds a couple of new ones, and constructs many formulas that are near-Russell.

Some accounts of human distinctiveness focus on anatomical features, such as bipedalism and brain size. Others focus on cognitive abilities, such as tool use and manufacture, language, and social cognition. Embodied approaches to cognition highlight the internal relations between these two groups of characteristics, arguing that cognition is rooted in and shaped by embodiment. This paper complements existing embodied approaches by focusing on an underappreciated aspect of embodiment: the appearance of the human body as condition of human sociality and cognition. (...) I approach this issue through Merleau-Ponty’s understanding of the animate body as an intertwining of perceiving and perceivable aspects. The eye is both an animal’s embodied, perceptual openness onto the world, and the means by which that experiential openness can be perceived by others. The morphology and appearance of its embodiment condition how an animal comes to understand others and itself as animate subjects. I interpret the perceivable appearance of the human eye and skin in comparison with those of other animals. An underappreciated dimension of human distinctiveness, I argue, is the way the human sense organs render human perceiving comparatively more perceivable to conspecifics. (shrink)

Aristotle’s De Interpretatione has been referred to as the most influential text to be written in the history of semantics. I argue, however, that it is Plato who lays the foundation for subsequent reflection on signification. In the Cratylus, Plato confronts the two prevalent views of his time on the nature of the relationship between a name and a thing named: conventionalism, which holds that there is an arbitrary, imposed relationship between names and what they name; and naturalism, which holds (...) that there is a natural relationship between names and what they name. The true originality of Plato’s line of reasoning consists in arguing that whether we begin with naturalism or conventionalism, we are soon forced to introduce a third, mediating term between word and thing into the relation of signification. Plato thus establishes the tertiary nature of the sign-relation, a position that Aristotle takes for granted. (shrink)

Long ago, when Alexander the Great asked the mathematician Menaechmus for a crash course in geometry, he got the famous reply ``There is no royal road to mathematics.'' Where there was no shortcut for Alexander, there is no shortcut for us. Still, the fact that we have access to computers and mature programming languages means that there are avenues for us that were denied to the kings and emperors of yore. The purpose of this book is to teach logic and (...) mathematical reasoning in practice, and to connect logical reasoning with computer programming in Haskell. Haskell emerged in the 1990s as a standard for lazy functional programming, a programming style where arguments are evaluated only when the value is actually needed. Haskell is a marvelous demonstration tool for logic and maths because its functional character allows implementations to remain very close to the concepts that get implemented, while the laziness permits smooth handling of infinite data structures. This book does not assume the reader to have previous experience with either programming or construction of formal proofs, but acquaintance with mathematical notation, at the level of secondary school mathematics is presumed. Everything one needs to know about mathematical reasoning or programming is explained as we go along. After proper digestion of the material in this book, the reader will be able to write interesting programs, reason about their correctness, and document them in a clear fashion. The reader will also have learned how to set up mathematical proofs in a structured way, and how to read and digest mathematical proofs written by others. This is the updated, expanded, and corrected second edition of a much-acclaimed textbook. Praise for the first edition: 'Doets and van Eijck's ``The Haskell Road to Logic, Maths and Programming'' is an astonishingly extensive and accessible textbook on logic, maths, and Haskell.'

The Christian church had its early development in the Hellenistic, Greco-Roman world and for that reason it can certainly be stated that the church was “Hellenized”. But how should we define this Hellenization? And what should be our judgement of it? The collection of essays entitled Hellenization revisited centers on an important theme.

Abstract: This article invalidates a central objection that has been brought up against Spinoza’s idea of idea doctrine as a theory of consciousness. Key point in the argument is that the perfection of ideas of ideas is as variable as the perfection of ideas and corresponds to the perfection of the associated bodies. This allows ideas of ideas to account for various degrees of consciousness. In its application to human beings the theory covers important aspects of consciousness: to know that (...) one knows a thing, to know what one knows and to know that is our mind that knows the thing. The doctrine is a theory of the self-reflectivity of ideas that explains the immediate awareness of thoughts. The author argues that the idea of idea doctrine is the make-up of a comprehensive theory of consciousness throughout nature. Keywords:. (shrink)

Since it has generally been accepted that to Spinoza attributes are real features of substance, the interpretation of his attribute definition has become a notorious problem. The reason is that interpreters have failed to see that the definition formulates a purely epistemological account of the state of affairs. The article presents and justifies such an interpretation. It will be shown that the definition in spite of its epistemological character implies a real ontological definition, which specifies the critical features of an (...) attribute. As to the reason why Spinoza has stated the definition in an ‘indirect way’, it is shown that it is likely that he has done so in order to have a more efficient, a more unambiguous and a more elegant definition. The relevance of the new interpretation is not only that it provides us with an interpretable, transparent attribute definition, but it also contributes to the establishment of a coherent picture of Spinoza’s metaphysics around this definition.

Radical and autopoietic enactivists disagree concerning how to understand the concept of sense-making in enactivist discourse and the extent of its distribution within the organic domain. I situate this debate within a broader conflict of commitments to naturalism on the part of radical enactivists, and to phenomenology on the part of autopoietic enactivists. I argue that autopoietic enactivists are in part responsible for the obscurity of the notion of sense-making by attributing it univocally to sentient and non-sentient beings and following (...) Hans Jonas in maintaining a phenomenological dimension to life-mind continuity among all living beings, sentient or non-sentient. I propose following Merleau-Ponty instead, who offers a properly phenomenological notion of sense-making for which sentience is a necessary condition. Against radicalist efforts to replace sense-making with a deflationary, naturalist conception of intentionality, I discuss the role of the phenomenological notion of sense-making for understanding animal behavior and experience.

This paper asks why information should ever be expressed vaguely, re-assessing some previously proposed answers to this question and suggesting some new ones. Particular attention is paid to the benefits that vague expressions can have in situations where agreement over the meaning of an expression cannot be taken for granted. A distinction between two different versions of the above-mentioned question is advocated. The first asks why human languages contain vague expressions, the second question asks when and why a speaker should (...) choose a vague expression when communicating with a hearer. While the former question is purely theoretical, the latter has practical implications for the computational generation of utterances in Natural Language Generation (NLG). (shrink)

Can we empathize with plants? Critics object that supposed empathy with plants entails anthropomorphic or zoomorphic projection. In reply, a phenomenological account of empathy claims to avoid this objection. However, phenomenological accounts of empathy center on one sentient (phenomenally conscious) mind accessing another. If plants are not sentient, then they appear to be inappropriate targets for empathy. I reply by exploring how the organic body is implicated in sentience, even if it is not usually focal. Interoceptive experience gives us indirect (...) access to our own organic body, and thus provides a basis for a problematic, paradoxical empathy with plants. (shrink)

Internet is often said to open up new avenues for a more direct and deliberative democracy. In this article, the notion of ‘deliberation’ will be problematized and a typology of political web sites will be developed. Next, three case studies of Dutch discussion sites are used to test the claim that the organizational structure, aim, control of content and kind of interactivity of political web sites can explain the level and quality of participation. Except for its mostly extreme elitist participation, (...) the research presented here gives a rather ambiguous picture of e-democracy at work. Not only are we confronted with more paradoxes than clear-cut answers, the question is raised whether notions such as the ‘public sphere’ are not more of a hindrance than a help in making sense of politics on the Internet.

This article explores a new reading of an important section of Part II of Spinoza’s Ethics. It recognizes that Spinoza actually differentiates between the human mind conceived from the viewpoint of its cause and the human mind conceived from the viewpoint of its nature. It shows, most importantly, that Spinoza assigns different objects to those ‘minds’. Consequently they represent different knowledge of the body. It will appear that the human mind in respect of its cause represents non-conscious knowledge of the (...) human body and that the human mind in respect of its nature represents conscious knowledge of the human body. It will be shown that knowledge of the inner processes of the human body and of the body per se belongs to the domain of non-conscious knowledge. The same conclusion will be obtained in an analysis that starts from the distinction between the formal and the objective being of the human mind. (shrink)

The book argues that mainstream economists, who base their analyses only on the economic motivation of people, fail to explain and understand real-life economic phenomena. The economic crisis, which began in 2008, illustrates the relevance of psychic and social motivations, especially when combined with each other. This book discusses orthodox and heterodox economics, and offers the reader ample material on philosophy of science, psychology and sociology. A multidisciplinary economic perspective is constructed in which economics, psychology, and sociology are integrated, and (...) this multidisciplinary approach offers an understanding of real-life problems. Moreover, it offers researchers a rich source for further analysis. (shrink)

The important conclusion of this article is that essences of singular things are not eternal in the sense of being distinctive eternal modes, as is generally held by Spinoza scholars. Both the essence and the existence of singular things are eternal in the sense that they are comprehended in God’s eternal nature, that is to say, in the sense that they follow necessarily from that nature. The second conclusion is that the essence and the existence of things are inseparable. There (...) are no essences of things when things do not exist. Another conclusion regards the meaning of ”formal essence’. It is argued that the formal essence of a thing is the essence of a thing that formally follows from an attribute. It is not in any sense opposite to the actual essence of a thing. The formal essence is simply the actual essence of a thing that formally follows from an attribute. (shrink)

Dans cet article, composé en hommage aux travaux de Peter Sharratt, l’auteur examine l’attitude de Pierre de La Ramée (Ramus) et d’Omer Talon à l’égard de l’Éthique à Nicomaque. En tant qu’humanistes, ces derniers s’occupent intensément des arts du discours. Tout en reconnaissant la nécessité d’un fondement éthique dans tout discours, ils se montrent violemment hostiles au traité aristotélicien. Le traité posthume de théologie composé par Ramus propose le Décalogue comme source exclusive de la morale chrétienne. Ramus et Talon refusent (...) de la sorte de s’engager dans la voie ouverte quelques décennies plus tôt par Ph. Melanchthon, qui avait intégré de manière originale la morale antique, notamment celle d’Aristote, dans la théologie protestante. Toutefois, vers la fin du xvie siècle, le philosophe hollandais Rodolphe Snellius, père adoptif du théologien Arminius, composera un traité de morale dans lequel il tente de concilier la morale aristotélicienne avec la méthode développée par Ramus et son équipe.

This interview with Jeremy Waldron covers three topics. Firstly, we dealt with the methodology debate, that is, the discussion about how to proceed in analyzing the nature of law. Does the question ‘What is law?’ require a descriptive analysis of the concept of law or, rather, a normative exercise in political philosophy? Secondly, we spoke about the role of law in response to historic injustice, especially in relation to the restitution of property rights. On this topic Waldron vindicates the ‘supersession-thesis’, (...) the idea that, due to changed circumstances and the passage of time, historic injustices become superseded. The third section of the interview is devoted to Waldron’s perspective on the citation of foreign law by national judges. (shrink)

This paper clarifies Merleau-Ponty’s distinction between speaking and spoken speech, and the relation between the two, in his Phenomenology of Perception. Against a common interpretation, I argue on exegetical and philosophical grounds that the distinction should not be understood as one between two kinds of speech, but rather between two internally related dimensions present in all speech. This suggests an interdependence between speaking and spoken aspects of speech, and some commentators have critiqued Merleau-Ponty for claiming a priority of speaking over (...) spoken speech. However, there is a sense in which Merleau-Ponty is right to emphasize the priority, namely, in terms of the ontological priority of the speaking subject with respect to language understood as a constituted cultural ideality. The latter only maintains its ontological status insofar as it is taken up by a language community. I favorably contrast Merleau-Ponty’s views on this question to those of the late Heidegger and de Saussure, and suggest potential applications of this clarified position for contemporary discussions in philosophy of language.

In recent years, social cognition approaches to human evolution and Material Engagement Theory have offered new theoretical resources to advance our understanding of the prehistoric hominin mind. To date, however, these two approaches have developed largely in isolation from one another. I argue that there is a gap between social- and material-centred approaches, and that this is precisely the sociomateriality of the appearance of ancestral hominin bodies, which evolved under selective pressure to develop increasingly complex, cooperative sociality. To get this (...) sociomaterial body in focus, I develop an esthesiological framework, appropriated from Merleau-Ponty (2003), for interpreting the expressive body in an evolutionary and comparative context. The guiding hypothesis of esthesiology is that before being rationality (social or material), “humanity is another corporeity” (Merleau-Ponty, 2003, p. 208). Esthesiology studies the appearance of the body and its sense organs as an intertwining locus of a sensing power (the ability to see, to touch, etc.) and a sensible character (the visible, touchable body). It is this dual-aspect character of the body that facilitates the most basic affective and sensorimotor modes of sociality. Examining these features from a comparative perspective, we find that the human body is distinctively suited to prosocial communication and cooperation: a more cooperative eye, an exposed and communicative skin. I thus propose a cooperative body hypothesis, by analogy with the cooperative eye hypothesis (Tomasello et al., 2007). Esthesiology provides a framework for integrating and interpreting a wide range of otherwise disconnected facts concerning human and nonhuman animal bodies, forms of life, cognition, and evolution, thereby bridging the gap between social cognition and material engagement perspectives. In doing so, however, it not only solves problems and proposes new directions of investigation, but also demands theoretical revisions from each. (shrink)

In this paper I develop a novel account of the phenomenality of language by focusing on characteristics of perceived speech. I explore the extent to which the spoken word can be said to have a horizonal structure similar to that of spatiotemporal objects: our perception of each is informed by habitual associations and expectations formed through past experiences of the object or word and other associated objects and experiences. Specifically, the horizonal structure of speech in use can fruitfully be compared (...) to that of a tool in use. The comparison suggests an account of our linguistic faculty as continuous with more foundational faculties of perception and action. I provide empirical corroboration of this account by drawing on recent neuroimaging studies of the multimodal, sensorimotor bases of speech comprehension. I then discuss how such an understanding of our linguistic ability helps advocates of embodied, non-representationalist accounts of cognition respond to a common objection. Critics grant that embodied approaches may be adequate to account for lower-level, online modes of cognition, such as perception and action, which directly engage their object. But they question whether such approaches can “scale up” to higher modes of cognition, such as imagination, memory, thought, and language, which can entertain absent, non-existent, or abstract objects. By providing a plausible account of the continuity of lower cognition and language-involving cognition, my approach responds to this objection, at least where language is concerned. (shrink)

Approaches to the naturalization of phenomenology usually understand naturalization as a matter of rendering continuous the methods, epistemologies, and ontologies of phenomenological and natural scientific inquiry. Presupposed in this statement of the problematic, however, is that there is an original discontinuity, a rupture between phenomenology and the natural sciences that must be remedied. I propose that this way of thinking about the issue is rooted in a simplistic understanding of the phenomenological reduction that entails certain assumptions about the subject matter (...) of phenomenology and its relationship to the natural sciences. By contrast, Merleau‐Ponty's first work, The Structure of Behavior, presents a radically different approach to the phenomenological reduction, one that traverses the natural sciences and integrates them into phenomenology from the outset. I outline the argument for this position in The Structure of Behavior and then discuss consequences for current methodological issues surrounding the naturalization of phenomenology, focusing on the relationship between empirical sciences of mind, phenomenological psychology, and transcendental phenomenology. This novel exegesis of Merleau‐Ponty's view on the reduction offers new insight into his oft‐quoted remark that the phenomenological reduction is impossible to complete. (shrink)

Our lives are full of inexactitude. We say a person is tall or an action is just without the precision of measurement on a dial. In this engaging account, Kees van Deemter explores vagueness, cutting across areas such as language, mathematical logic, and computing. He considers why vagueness is inherent, and why it is important in how we function.

The most valuable finding of my first sightseeing trip was that medieval Europe was the seat of Christendom and that Christianity defines the West. I was amazed to see that Europe reveals so much of its past. I had not had such an experience in the United States, where I had lived as a student and then as a professor of economics.As I glimpsed the West, I found myself rediscovering Confucian civilization and how much I am still Confucian, although I (...) was born into a Presbyterian family in Korea. But then, Korea is the most Confucian country. Curious about the West since my first trip, whenever I can I have toured Europe in search of the meaning of the West.While travelling in Europe, my mind often jumps back to my early life in Korea and Japan. I am struck by the vivid contrast in appearance between medieval European towns and Asian towns, which were grey and as flat as pancakes. Medieval towns are stony and solid. Nothing is flimsy. Shaped by spires, domes, and towers, a European town's silhouette rises and falls like a stock market graph. Europeans obviously loved the vertical emphasis. A traveller can see either a soaring church tower or a castle keep miles away on the horizon. Churches predominate, as if to emphasize that the main business of the town is the worship and glorification of God. (shrink)

In his late lecture course titled “Nature and Logos: The Human Body” (1959-1960), Merleau-Ponty proposed that we understand human symbolism, language, and reason by viewing the human being initially as a variant on animal embodiment and perception prior to being a rational animal. To elaborate this project, he outlined an “esthesiology” informed by the study of evolution. However, in the sketches that survive of “Nature and Logos,” we find neither a detailed explanation of how Merleau-Ponty understood this approach nor its (...) concrete execution with respect to the human body. In this paper I reconstruct Merleau-Ponty’s esthesiology. An animate body possesses two “sides”: it is a sensing organism open onto the world and a sensible part of the natural world. Visual animals such as humans can see, see themselves, and be seen by others. To understand their way of life, we must study not only the body’s capacities for perception and action, but also how those capacities are seen by other organisms, especially conspecifics. The body’s visibility shapes the social prospects of a species and its potential for developing complex sociality, language, and cognition. I apply this basic esthesiological principle to study the human eye. Both in its vision and its visibility, the human eye is a distinctive variation of animality and one that conditions and shapes human sociality and cognition. I develop this insight with respect to a central philosophical theme of Merleau-Ponty’s late work, the relation of the visible and the invisible. I conclude by discussing the importance of Merleau-Ponty’s esthesiology for his late thought and current discussions of the naturalization of phenomenology. (shrink)
