The purpose of this study was to know the relationship between student perception towards mathematics teacher with mathematics academic performace. The population of the study were all students of class VIII SMPN 8 Cirebon in the academic year 2014/2015, with the number of students 287 people. The sampling technique used proportional random sampling, and the sample size was 56 students. Data collection techniques used: 1) Questionnaire of Perceptions towards Mathematics teacher, and 2) The results of student mathematics learning test. The (...) result of correlation analysis show no significant correlation between students perception towards teacher and academic performance (r= .155, p= .254). (shrink)

The problem of resurrection, one of the most important issues in the philosophy and theology. Some of Muslim philosophers and the vast majority of theologians always discussed about this topic. Some of Muslim philosophers accepted this problem and prove it, but, in quality of occurrence of them, they have differ believe from each other. However, some of Muslim theologians except those who believe in transmogrification, they consider the resurrection to be one of the principle of religion, beside monotheism and prophecy. (...) Moreover, they proved the principle of resurrection through reasons, and explanations them elaborates through the Holy Quran and Prophetic saying (Traditions- Hadith). Avicenna and Suhrawardi have been proving resurrection. Of course, for prove of this problem, they adopted of different manner from Muslim Theologians. Both of philosophers according to codify of ordinary psychological system, have proved and explanation this issue. Thus, for understand of Avicenna and Suhrawardi’s eschatology. First of all, we must understand of their psychological system. Furthermore, in this paper, we will discuss about survival of the soul according to immaterial soul and perfecting of soul as two premises for prove of resurrection. (shrink)

This chapter examinates the concept of Baroque habits in its various declensions, dwelling in particular on aesthetic habits through the case study of Guarino Guarini’s Chapel of the Holy Shroud in Turin. In the first part three declensions of Baroque habits, linked together by profound implications, are identified: habits of knowledge, referred to the ideal of Baroque encyclopedism; moral habits, framed in the Baroque practices of government of affects; and aesthetic habits, consisting in regimes of or- dering of sensible experience (...) which finds in the Wunderkammer one of its highest manifestations. In the second part of this chapter, these concepts are applied and further elaborated in the light of one of the greatest results of European Baroque, the Guarinian Chapel. Through the example of the Turinese architecture it is demon- strated how Baroque representative practices perform a gesture of immanentization of the transcendent principle by composition of light and application of geometry. Such “sensible metaphysics” is aimed at both the government of affects and at the creation of a habitable space of experience, where the infinite transcendence of Christian divinity becomes source and object of habits.

This paper proposes a comparison between the myth of Prometheus and Pliny the Elder’s account of the origins of painting to assess the technical characterof images. Such a character is seen as a precondition for understanding their epistemological value, as well as for supporting the need for hermeneutics at any level of artificial intervention. Finally, part of Horst Bredekamp’s work will be presented as an example of a methodology that combines hermeneutics and iconology based on such a technical character.

Humanities and its branches are related to many disciplines and even influence them. It can be claimed that everything that is related to humans and human social life is also related to humanities and can also be influenced by humanities. Artificial intelligence is one of the phenomena that is related to humans, and based on this, the question of this paper is whether humanities is related to artificial intelligence and whether it has the ability to influence it. Three assumptions are (...) made to answer this question. In the first and second assumptions, it is proved that humanities are related to AI and even influence it. Since artificial intelligence is man-made and related to humans, it has the ability to be guided by humanities. Furthermore, humanities can be effective in AI through the ethics. In the second assumption, it is also claimed that artificial intelligence is recognized by humans and humanities, so it can be influenced by humanities, because anything that can recognize something else can also influence it. The third assumption is that humanities are not able to influence AI and the reason is that humanities and artificial intelligence are two separate fields. -/- . (shrink)

Avicenna has placed the discussion of bliss and happiness as the main axis of the eighth Namat of ishārāt wa-al-tanbīhāt, and he has dedicated the first two chapters of this Namat to the issue of the originality of pleasure and intellectual happiness and its strength compared to other pleasures. In the first chapter, Avicenna has addressed the anteriority of internal pleasure over external pleasure by expressing an "Wahm" and "Tanbih", and he has rejected the views of those who make pleasure (...) exclusive to external issues. On the other hand, he also mentioned the second chapter as a sequel to the first chapter and in that he refuted the promise of those who reckon that happiness is exclusive in sensual matters. In this way, Avicenna's purpose in these two chapters is to prove the pleasure and intellectual happiness and its superiority over other pleasures. As a matter of fact, Avicenna has made this discussion the basis for other discussions of this Namat, and this study will aim to analyze the content of these two chapters. (shrink)

The discussion of artificial intelligence (AI) as a newly emerging phenomenon in the present era has always been faced with various ethical challenges. The expansion of artificial intelligence is inevitable, and since this phenomenon is related to the human and social world, anything related to humans and society falls within the realm of morality and rights. In doing so, it must be understood whether the use of artificial intelligence is an ethical matter or not. Furthermore, do humans have the right (...) to use it or not? It seems that Al-Farabi's thought in the realm of practical wisdom can provide an answer to this issue. By reflecting on the theories of this prominent philosopher in civil philosophy, the theory of natural rights is obtained, and on the other hand, Al-Farabi's ethical opinions are also consistent with the theory of natural rights and, in general, with Al-Farabi's civil philosophy. It can, therefore, be argued that, one can consider and elucidate this issue through the lens of Al-Farabi's ethical and civil school of thought. -/- . (shrink)

Avicenna, in his treatise called "Al-Siyasāt al-Ahliyyah", has discussed various topics about household management, among which are discussion about family formation and discussion about wife and children. The discussions about wife and child in this treatise are not only about family management, how to deal with wife and child. However, the issues related to women's rights and children's rights are also seen in it. The two fundamental questions of this paper are whether women's rights and children's rights, which are found (...) in Avicenna's views in this treatise, are comparable to the provisions of the Convention on the Elimination of All Forms of Discrimination Against Women and the Convention on the Rights of the Child (first question), and if they can be compared, do they confirm or deny each other? Hence, the topics that will be examined in this paper will be in line with the answers to these two questions in a descriptive-analytical method. (shrink)

Natural rights play a fundamental role in the political, legal, and economic system of John Locke. Many of his views are based on natural rights. Although Locke is not the first scholar to discuss natural rights, and before him, other thinkers have theorized about it in different eras and intellectual traditions, it must be claimed that Locke is a modern natural rights theorist and has presented a novel interpretation of this theory. Locke's natural rights are based on equality and individual (...) independence. Freedom, life, and property are the three basic pillars of Locke's theory. However, many international charters that defend human rights also in some way protect personal freedom, life, and property of individuals around the world. One of the international agreements is the Convention on the Rights of the Child in the United Nations, which defends the freedom and security of children worldwide and guarantees their basic rights. In this convention, natural rights patterns, especially those of Locke, can be seen, and he is also considered the spiritual father of human rights and one of the sources of modern human rights, the foundations of natural rights. Therefore, the main purpose of this paper is to examine the foundations of natural rights in the Convention on the Rights of the Child and compare them with the foundations of John Locke. (shrink)

Suhrawardi is among the philosophers who, compared to other philosophers, developed his intellectual system in an innovative manner. Suhrawardi’s illuminative intellectual system is the result of his thoughts in philosophy and mysticism, and the ultimate of his illuminative school is to achieve the station of mystic perception and theosophy using intuition and reasoning. The pure soul is an important pillar in the wayfarer’s intuition; and since the soul has descended from the world of the dominant lights to the world of (...) nature, it may have diseases just like the body. In his treatises, the Master of Illumination opened a new door in philosophy by discussing the disease of the soul, and sought to provide a mystical and ethical solution for the treatment of the human’s rational soul through his illuminative way of thinking. Suhrawardi’s method for treating the diseases of the soul is expressed as an allegory because it is considered as a part of his mystical materials; and it is regarded as a moral matter because it is a prescription for all wayfarers. By recognizing the symbols in Suhrawardi’s allegorical treatises, we can identify his moral way of treating the diseases of the soul. (shrink)

The principle of causality is one of the most fundamental principles that has been discovered in the history of philosophy and science. Several foundations revolve around this concept. The importance of this principle in classical physics lies in giving physicists the ability to predict phenomena. Furthermore, due to causality is recognized as a fundamental principle in classical physics. With the introduction of the principle of uncertainty, the principle of causality is empirically called into question. Because the claim of the principle (...) of uncertainty in quantum mechanics is that the relationships between fundamental particles are not causally related to each other, and even the behavior of an electron or a subatomic particle is not based on the principle of causality. If we want to identify the speed of particles, we will not be able to identify their state, and if we want to determine their state, we will not be able to identify their speed. The best way to resolve this conflict is to bring the discussion into philosophy, which is exactly what has been done in Islamic philosophy. The concept of causality in Western philosophy seems to be based on Newtonian concepts. But what has been stated in Islamic philosophy is based on metaphysical concepts, and therefore the principle of uncertainty cannot contradict the concept of causality in Islamic philosophy, especially what has been discussed in the philosophy of Avicenna and Allameh Tabataba'i.

Fārābī's legal theory, which is among his views in civil wisdom, consists of three things: foundation, source, and purpose. The foundations of Abu Nasr al-Fārābī's virtuous law is natural law, which is compatible with the objectives of Islamic Law. Furthermore, the source of the existing laws in the virtuous city, which is codified by the first ruler, is the divine revelation and tradition. Some divine traditions or natural laws are understood by common sense, and some others, which are hidden from (...) the understanding of the majority, are inspired by revelation to the first ruler of virtuous city, or the first ruler understands them by using his acquired intellect. The aim of the first ruler, which is also the aim of the laws of virtuous city, is the happiness. The problem of this study is to investigate and explain these three things (foundation, source, and purpose) with descriptive-analytical method, which can be considered as the theory of virtuous law, which is the same as Fārābī's legal theory.

Suhrawardī has presented arguments to support the existence of wājib al-wujūd in many of his works. One of the most fundamental of these arguments, which also has a forward-looking feature, is the one he presents in his books al-Talwīḥāt and Ḥikmah al-Ishrāq. To prove the existence of God, Suhrawardī devised three arguments in al-Talwīḥāt and one argument in Ḥikmah al-Ishrāq, all of which are interpretations of the ṣiddīqīn argument. In this article four of Suhrawardī’s arguments, three of them in al-Talwīḥāt (...) and one of them in Ḥikmah al-Ishrāq are reviewed. the main aim of this study is to analyze and explain Suhrawardī’s arguments, due to their importance in philosophy and theology, with the descriptive-analytical method and using library-based collecting data. The arguments presented in the al-Talwīḥāt are succinct, and what made these claims essential was the evaluation of their robustness and content. The significance of his first and third arguments in this book is that they do not require the denial of the vicious circle as a precondition, and by assuming the likelihood of both the vicious circle and infinite regress, the necessity of existence is demonstrated. On the other hand, his argument in Ḥikmah al-Ishrāq, which, like his second argument, is based on the refutation of the vicious circle and infinite regress, includes innovative features and should be investigated thoroughly. -/- .

If we consider Kitāb al-Milla as the foundation for Al-Farabi's other civil and political thoughts, we are not making an exaggerated claim. Abu Nasr Al-Farabi presents the philosophy of his civil and political theory through this treatise, embedding his ideas within it. Upon reflecting on the content of this work, it can be clearly divided into two parts. In the first part, Al-Farabi discusses issues that serve as the foundation for the second part, which is the science of civics. In (...) the second part, which is the focus of this study, he addresses matters that constitute the philosophy of civics. A close examination of the second section of Kitāb al-Milla reveals that Al-Farabi speaks of two enumerations: one concerning happiness and the other concerning politics. In general, these two elements make up the issues of the science of civics. (shrink)

Al-Fārābī's discussed fundamental issues in the first ten sections of Kītāb al-Mīllah briefly. Defining the nation (religion), describing the types of societies, dividing the nation (religion) into opinions and actions, and mentioning each of them, synonyms of the nation with other concepts such as religion and shārīʿa, the method of inferring the opinions of the nation, the similarity of the virtuous nation to philosophy, the relationship between the two components of the nation with theoretical philosophy and phronesis (practical philosophy), dealing (...) with fallacies using topic and rhetoric, the reasons for not expressing some laws by the first ruler, the conditions of the rulers after the first ruler, the wisdom, jurisprudence and virtue of the nation's ruler, and discussing the philosophical nature of jurisprudence, the most important contents of Al-Fārābī's in this ten section. On the other hand, it must be claimed that various theories can be extracted from Kītāb al-Mīllah: 1. Revelation as the highest faculty of reason; 2. The unity of theoretical philosophy and Phronesis- the unity of theoretical and practical reason; 3. Philosophy of jurisprudence; 4. Governance philosophy; 5. shārīʿa purposes; 6. Aristocracy; 7. Philosophical jurisprudence. In this paper, in addition to the translation of the first ten sections of Kītāb al-Mīllah, its content is also explained and these seven ideas are extracted from this treatise. (shrink)

Plato is among the most influential philosophers in the course of history, and the range of his ideas about different issues makes other scholars impressed. Considering his various views on varied subjects, one can argue that many ideas of the thinkers originated from Plato’s ideas in the contemporary world. Plato, in different positions, discussed women and their equality with men, especially in Republic Book V. The study of the ideas makes one suppose that the book explores the roots of feminist (...) theory. In Book V, Plato deals with the equality of women and men related to learning different issues and positions. Besides, he has discussed the children-sharing system resulting in the elimination of the private family system. Plato’s opinions are highly disputed; on the one hand, his ideas are considered feminist, and on the other hand, however, they are seen with no relation to feminist philosophy. The present paper aims to judge opinions related to women in the Republic Book V. -/- . (shrink)

Suhrawardi created a revolution in the field of Iranian and Islamic thought by compiling the Illuminated Philosophy. The philosophy of Suhrawardi, which includes the collection of works and philosophical and mystical thoughts of Suhrawardi, is well presented in his book Hikma al-Ishraq. Unlike Farabi, Suhrawardi did not write an independent work about Utopia, but he spoke about the ideal ruler and the right to rule. Moreover, in his allegorical works, more than anything else, he pointed out moral points that can (...) lead the people of a society to salvation. Suhrawardi's philosophy is based on the originality of light, which shows that he had an opinion on the philosophers of Ancient Iran. In addition, Suhrawardi has repeatedly referred to Khosrvanion and Ancient Persian Scholars such as Zoroaster and Key Khosro and, for example, considered Key Khosro's government to be a desirable government in terms of politics and government. Another pillar of Suhrawardi's thought is the Quran and Islamic traditions, and therefore, his opinion about the government and ruler is consistent with Islamic teachings. In addition, he considered himself indebted to the divine philosophers of Greece such as Pythagoras and Plato and other divine scholars of the world such as Hermes, and he also took many of the opinions of his predecessor philosophers such as Farabi and Avicenna; Therefore, it can be assumed that he agrees with Farabi in many respects about utopia and its governing characteristics and conditions.

The paper aims to understand whether morphology can be framed as a language for aesthetics. In particular, whether Olaf Breidbach’s contribution can determine its fundamental terms. These are related to the notion of forms and images. Hence, the paper is structured into three parts: i) framing of research on morphology in Ger-many; ii) analysis of Goethe’s method and vocabulary from an aesthetic standpoint; iii) presentation of Breidbach’s proposal in relation to Goethe.

I argue that an analogy between pains and sounds suggests a way to give an objective account of pain which fits well with a naïve perceptualist account of feeling pain. According to the proposed metaphysical account, pains are relational physical events with shared qualitative nature, each of which is constituted by tissue damage and the activation of nociceptors. I proceed to show that the metaphysical proposal is compatible with platitudes about pains being animate, private, and self-intimating states.

Poetry is sometimes used in a logical argument sense of the five major arguments, and the meaning behind it is the argument and expression that its common element is imagination. In fact, the distinguishing feature of poetry from other arguments is the poetic nature of the language. Poetry is sometimes used in an artistic sense and can be considered one of the seven arts. The definition of artistic poetry can be understood as a speech that is firstly rhythmic, secondly rhyming, (...) and thirdly imaginative. In this article, poetry is used in the second sense, as poetry in the artistic sense can have a sublime aspect. In fact, poetry in the first sense has an industrial and organic aspect, while poetry in the second sense has an authentic aspect. Mulla Sadra, in addition to writing in prose in rational knowledge, has also expressed many of his sublime philosophical ideas in poetic language. What Sadr al-Muta'allihin has written in poetic form is poetry in the second sense because it has both the three conditions of being rhythmic, rhyming, and imaginative, as well as expressing sublime wisdom in poetic and sublime art language.

Since political polarization significantly impacts contemporary politics and democracy, much of the research in the social sciences is dedicated to this topic. In recent times, philosophers joined the discussion related to the research on political polarization, primarily in the fields of political philosophy and political epistemology.

In (...) a nutshell, to find solutions for a way out of political polarization, I will be looking in the direction of boosting epistemic rationality and fostering communication in conditions of tolerance and equality.

Matija Vlačić Ilirik was one of the pillars of Luther’s Reformation. In a special way, he dedicated himself to one of its most important issues – the understanding of the Scriptures, and can, therefore, be considered a significant instigator of the founding of modern hermeneutics. As an excellent connoisseur of classical languages (Hebrew, Greek and Latin) he recognized the importance and dealt with many issues of language, grammar, logic, and dialectic, as essential prerequisites for understanding everything which exists, and hence (...) of the written text also. In this connection, his skepticism towards philosophy is apparent, since the main source of theological cognition, for him, is revelation, and not the human reason, which was principally destroyed by Original Sin. He found the confirmation of his ideas in the current debates with both proponents and opponents of the Reformation, as well as in his research into church history, wherein he incessantly tried to find the witnesses of the truth, as he perceived it.

In this paper I will discuss a recent attempt of justifying democracy and its authority. It pertains to recently published papers by Niko Kolodny, which complement each other and taken together practically assume a form of a monograph. It could be said that Kolodny's approach is a non-standard one given that he avoids typical ways of justifying democracy. Namely, when a justification of democracy is concerned, Kolodny maintains that it is necessary to offer a kind of an independent justification. It (...) is not so much that he insists that the usual approaches are wrong as much as that an independent justification is necessary in order to discern what it is that gives them their significance. Kolodny's independent justification of democracy is based on the idea of social equality. In this paper I will try to reconstruct and critically assess Kolodny's approach by paying special attention to the question of democratic authority. (shrink)

The aim of this work is to understand the retraction phenomenon in the arts and humanities domain through an analysis of the retraction notices – formal documents stating and describing the retraction of a particular publication. The retractions and the corresponding notices are identified using the data provided by Retraction Watch. Our methodology for the analysis combines a metadata analysis and a content analysis (mainly performed using a topic modeling process) of the retraction notices. Considering 343 cases of retraction, we (...) found that many retraction notices are neither identifiable nor findable. In addition, these were not always separated from the original papers, introducing ambiguity in understanding how these notices were perceived by the community (i.e., cited). Also, we noticed that there is no systematic way to write a retraction notice. Indeed, some retraction notices presented a complete discussion of the reasons for retraction, while others tended to be more direct and succinct. We have also reported many notices having similar text while addressing different retractions. We think a further study with a larger collection should be done using the same methodology to confirm and investigate our findings further. (shrink)

Philosophers of science often suggest that the key feature of scientific research is striving for objectivity and that we should evaluate scientific practice by whether it is objective or not. In this paper, we will analyze several definitions of scientific objectivity to illustrate the complex meaning of this term and examine its role in evaluating scientific practice. First, we will introduce Lorraine Daston and Peter Galison's standpoint concerning the historical connection between the genesis and development of scientific objectivity and the (...) practices of visual representation in the research practice of the 19th and 20th centuries. We will accomplish that by outlining the process of establishing scientific objectivity as an epistemic virtue and a vital feature of the "scientific self ". Subsequently, using Heather Douglas and Mar-ianne Janack's conceptual analysis of scientific objectivity, we will show that scientific objectivity is characterized by an "irreducibility of meaning" and an "endemic instability" caused by the overuse of metaphors in defining this concept. In the final section, in light of contemporary problems such as the crisis of reproducibility, we examine to what extent philosophical definitions help test the objectivity of scientific practice and point to an intriguing attempt to define "objectivity for the research worker" using the model proposed by Noah van Dongen and Michał Sikorski.

The phenomenon of self-love elicits conflicting reactions. Some believe it is the key to happiness, while others are skeptical.

In this thesis, I propose and defend a theory according to which committing oneself to knowing the proposition expressed counts as an assertion of that proposition. A consequence of this view is the knowledge account of assertion, according to which one asserts that p correctly only if one knows that p. In support of this approach, I offer a strategy of identifying an assertion’s “normative consequences”, types of act that normally take place as a result of one’s making an assertion (...) incorrectly. I outline two such phenomena: retraction and disavowal of knowledge. In continuation, I put the theory to test and critically examine four sets of objections against it, arguing that it can convincingly defuse them. Finally, I discuss two related issues: I maintain that by performing “aesthetic assertions” one also normally performs a non-assertoric speech act of recommendation, and argue for the possibility of “non-linguistic assertions”, whose content is expressed by gestures in appropriate contexts.

Breast cancer is the leading cause of death among women with cancer. Computer-aided diagnosis is an efficient method for assisting medical experts in early diagnosis, improving the chance of recovery. Employing artificial intelligence (AI) in the medical area is very crucial due to the sensitivity of this field. This means that the low accuracy of the classification methods used for cancer detection is a critical issue. This problem is accentuated when it comes to blurry mammogram images. In this paper, convolutional (...) neural networks (CNNs) are employed to present the traditional convolutional neural network (TCNN) and supported convolutional neural network (SCNN) approaches. The TCNN and SCNN approaches contribute by overcoming the shift and scaling problems included in blurry mammogram images. In addition, the flipped rotation-based approach (FRbA) is proposed to enhance the accuracy of the prediction process (classification of the type of cancerous mass) by taking into account the different directions of the cancerous mass to extract effective features to form the map of the tumour. The proposed approaches are implemented on the MIAS medical dataset using 200 mammogram breast images. Compared to similar approaches based on KNN and RF, the proposed approaches show better performance in terms of accuracy, sensitivity, spasticity, precision, recall, time of performance, and quality of image metrics.

As historically acknowledged in the Reasoning about Actions and Change community, intuitiveness of a logical domain description cannot be fully automated. Moreover, like any other logical theory, action theories may also evolve, and thus knowledge engineers need revision methods to help in accommodating new incoming information about the behavior of actions in an adequate manner. The present work is about changing action domain descriptions in multimodal logic. Its contribution is threefold: first we revisit the semantics of action theory contraction proposed (...) in previous work, giving more robust operators that express minimal change based on a notion of distance between Kripke-models. Second we give algorithms for syntactical action theory contraction and establish their correctness with respect to our semantics for those action theories that satisfy a principle of modularity investigated in previous work. Since modularity can be ensured for every action theory and, as we show here, needs to be computed at most once during the evolution of a domain description, it does not represent a limitation at all to the method here studied. Finally we state AGM-like postulates for action theory contraction and assess the behavior of our operators with respect to them. Moreover, we also address the revision counterpart of action theory change, showing that it benefits from our semantics for contraction. (shrink)

In graph theory, the concept of domination is essential in a variety of domains. It has broad applications in diverse fields such as coding theory, computer net work models, and school bus routing and facility lo cation problems. If a fuzzy graph fails to obtain acceptable results, neutrosophic sets and neutrosophic graphs can be used to model uncertainty correlated with indeterminate and inconsistent information in arbitrary real-world scenario. In this study, we consider the concept of domination as it relates to (...) single-valued neutrosophic incidence graphs (SVNIGs). Given the importance of domination and its utilization in numerous fields, we propose the application of dominating sets in SVNIG with valid edges. We present some relevant definitions such as those of valid edges, cardinality, and isolated vertices in SVNIG along with some examples. Furthermore, we also show a few significant sets connected to the dominating set in an SVNIG such as independent and irredundant sets. We also investigate a relationship between the concepts of dominating sets and domination numbers as well as irredundant and independence sets in SVNIGs. Finally, a real-life deployment of domination in SVNIGsis investigated in relation to COVID-19 vaccination locations as a practical application. (shrink)

This paper aims to answer a basic question: is it possible to forge democratic citizenship through various online tools that are already available? To answer this question, I introduce the conception of digital political identities, i.e., the ways in which online environments contribute to creating, maintaining, and changing political identities. Because the well-functioning of democracy rests on citizens with the ability to make informed decisions, vote, and engage in public deliberation, this paper is looking for new and innovative online tools (...) for participating in meaningful online deliberation, acquiring accurate information in the digital space, and making informed voting decisions. By introducing the conception of digital political identities and linking it to online tools that can improve democracy and citizen engagement, I aim to make further progress in cutting edge research on the relationship between digital technologies and democracy. In a nutshell, I am mainly concerned with proposing and defending a normative framework for the use of various online tools that could foster digital democracy. (shrink)

Traditionally, consistency is the only criterion for the quality of a theory in logic-based approaches to reasoning about actions. This work goes beyond that and contributes to the metatheory of actions by investigating what other properties a good domain description should have. We state some metatheoretical postulates concerning this sore spot. When all postulates are satisfied we call the action theory modular. Besides being easier to understand and more elaboration tolerant in McCarthy’s sense, modular theories have interesting properties. We point (...) out the problems that arise when the postulates about modularity are violated, and propose algorithmic checks that can help the designer of an action theory to overcome them. (shrink)

In this paper I offer a conceptually tighter, quasi-Fregean solution to the concept horse paradox based on the idea that the unterfallen relation is asymmetrical.

The solution is only ‘quasi’- Fregean in the sense that (...) it rejects Frege’s claims about the ontological import of natural language and his analysis thereof. (shrink)

To explain the evolutionary emergence of uniquely human skills and motivations for cooperation, Tomasello et al. (2012, in Current Anthropology 53(6):673–92) proposed the interdependence hypothesis. The key adaptive context in this account was the obligate collaborative foraging of early human adults. Hawkes (2014, in Human Nature 25(1):28–48), following Hrdy (Mothers and Others, Harvard University Press, 2009), provided an alternative account for the emergence of uniquely human cooperative skills in which the key was early human infants’ attempts to solicit care and (...) attention from adults in a cooperative breeding context. Here we attempt to reconcile these two accounts. Our composite account accepts Hrdy’s and Hawkes’s contention that the extremely early emergence of human infants’ cooperative skills suggests an important role for cooperative breeding as adaptive context, perhaps in early Homo. But our account also insists that human cooperation goes well beyond these nascent skills to include such things as the communicative and cultural conventions, norms, and institutions created by later Homo and early modern humans to deal with adult problems of social coordination. As part of this account we hypothesize how each of the main stages of human ontogeny (infancy, childhood, adolescence) was transformed during evolution both by infants’ cooperative skills “migrating up” in age and by adults’ cooperative skills “migrating down” in age.
