Natural selection is commonly seen not just as an explanation for adaptive evolution, but as the inevitable consequence of “heritable variation in fitness among individuals”. Although it remains embedded in biological concepts, such a formalisation makes it tempting to explore whether this precondition may be met not only in life as we know it, but also in other physical systems. This would imply that these systems are subject to natural selection and may perhaps be investigated in a biological framework, where (...) properties are typically examined in light of their putative functions. Here we relate the major questions that were debated during a three-day workshop devoted to discussing whether natural selection may take place in non-living physical systems. We start this report with a brief overview of research fields dealing with “life-like” or “proto-biotic” systems, where mimicking evolution by natural selection in test tubes stands as a major objective. We contend the challenge may be as much conceptual as technical. Taking the problem from a physical angle, we then discuss the framework of dissipative structures. Although life is viewed in this context as a particular case within a larger ensemble of physical phenomena, this approach does not provide general principles from which natural selection can be derived. Turning back to evolutionary biology, we ask to what extent the most general formulations of the necessary conditions or signatures of natural selection may be applicable beyond biology. In our view, such a cross-disciplinary jump is impeded by reliance on individuality as a central yet implicit and loosely defined concept. Overall, these discussions thus lead us to conjecture that understanding, in physico-chemical terms, how individuality emerges and how it can be recognised, will be essential in the search for instances of evolution by natural selection outside of living systems.

This paper identifies the different normative ethical arguments stated and suggested by Arjuna and Krishna in the Gītā , analyzes those arguments, examines the interrelations between those arguments, and demonstrates that, contrary to a common view, both Arjuna and Krishna advance ethical theories of a broad consequentialist nature. It is shown that Krishna’s ethical theory, in particular, is a distinctive kind of rule-consequentialism that takes as intrinsically valuable the twin consequences of mokṣa and lokasaṃgraha . It is (...) also argued that Krishna’s teachings in the Gītā gain in depth, coherence, and critical relevance what they lose in simplicity when the ethical theory underlying those teachings is understood as a consequentialism of this kind rather than as a deontology.

Generic sentences (e.g., bare plural sentences such as “dogs have four legs” and “mosquitoes carry malaria”) are used to talk about kinds of things. Three experiments investigated the conceptual foundations of generics as well as claims within the formal semantic approaches to generics concerning the roles of prevalence, cue validity and normalcy in licensing generics. Two classes of generic sentences that pose challenges to both the conceptually based and formal semantic approaches to generics were investigated. Striking property generics (e.g. “sharks (...) bite swimmers”) are true even though only a tiny minority of instances have the property and thus pose obvious problems for quantificational approaches, and they also do not seem to characterize kinds in terms of the principled or statistical connections investigated in previous research ( Prasada and Dillingham, 2006 ; Prasada and Dillingham, 2009). The second class — minority characteristic generics (e.g. “ducks lay eggs”) — also poses serious problems for quantificational accounts, and appears to involve principled connections even though fewer than half of its instances have the relevant property. The experiments revealed three principal discoveries: first, striking generics involve neither principled nor statistical connections. Instead, they involve a causal connection between a kind and a property. Second, minority characteristic generics exhibit the characteristics of principled connections, which suggests that principled connections license the expectation that most instances will have the property, but do not require it. Finally, the experiments also provided evidence that prevalence and the acceptability of generics may be dissociated and provided data that are problematic for normalcy approaches to generics, and for the idea that cue validity licenses low prevalence generics. As such, the studies provided evidence in favor of a conceptually based approach to the semantics of generics ( Leslie, 2007 ; Leslie, 2008; see also Carlson, 2009). (shrink)

Nominal concepts represent things as tokens of types. Recent research suggests that we represent principled connections between the type of thing something is (e.g., DOG) and some of its properties (k‐properties; e.g., having four legs for dogs) but not other properties (t‐properties; e.g., being brown for dogs). Principled connections differ from logical, statistical, and causal connections. Principled connections license (i) the expectation that tokens of the type will generally possess their k‐properties, (ii) formal explanations (i.e., explanation of the presence of (...) k‐properties in tokens of a type by reference to the type of thing it is), and (iii) normative expectations concerning the presence of k‐properties in tokens of the type. The present paper investigates the hypothesis that representing principled connections requires representing properties as aspects of being the relevant kind of thing (Aspect Hypothesis). Experiment 1 provides a direct test of the Aspect Hypothesis. Experiments 2 and 3 provide indirect tests of the Aspect Hypothesis. All three experiments provide support for the Aspect Hypothesis. Experiment 4 investigates a prediction of the Aspect Hypothesis concerning the manner in which formal explanations are licensed by principled connections. Finally, Experiment 5 investigates a prediction of the Aspect Hypothesis concerning the nature of the normative expectations licensed by principled connections. Together these results provide strong evidence for the idea that representing principled connections involves representing a property as being an aspect of being a given kind of thing. The results also help clarify the manner in which formal explanation differs from other modes of explanation. Finally, the results of the experiments are used to motivate a proposal concerning the formal structure of the conceptual representations implicated by principled connections. This structure provides a domain‐general way of structuring our concepts and embodies the perspective we take when we think and talk of things as being instances of a kind. (shrink)

Since the late 1900s the business world has been under increasing pressure to demonstrate responsible social behaviour and the pressure continues to grow. Today, the role of business in society is on the Boardroom agenda and at stake are corporate reputation, innovation, competitiveness and growth. It is a clarion call, that either, the CEO and the Board manage it or someone else will manage it for them. As we know that we cannot solve our problems with the same level of (...) thinking that created them; therefore it is imperative that we look beyond the 20th century’s scientism and materialism dominated worldly ways for solutions. In view of the above, I believe that the ‘Indian Philosophy of Consciousness’ which focuses on practicing “better-worldliness” rather than “worldliness” and has developed over the past 4000 years has the potential to help business. Better worldliness is ‘a disposition towards life that is based on a Dharmic (righteous) way of conduct; a conduct with compassion and forbearance for fellow man, no matter what the nationality, or the colour of the skin, religion or caste.’ Society expects similar compassion and forbearance from business.

We simultaneously live in two worlds—our internal world of thoughts, values, desires, and experiences; and our external world in which we are born, and perform actions. Modernity, despite successfully developing our external world, has failed to develop our internal world. This has resulted in our lower nature being unleashed and a crisis of morals and values taking over society. This paper, drawing from the “science of consciousness” as detailed in the Indian tradition, looks at the nature of modernity and how (...) we can address the challenges being posed by it, by training our consciousness to higher levels.

Kautilya (4th Century B.C.) is a legendary figure in India for not only writing Arthashastra, a treatise that deals extensively with the strategies for building and running a nation based on strong fundamentals of economics and the wisdom of the leader, but also for making Chandragupta Maurya the king of Magadha whose empire later on became the largest empire ever seen in the Indian history. This paper is an attempt to identify the dimensions of wise leadership to subsequently arrive at (...) a wise leadership development model for contemporary times based on the philosophy of Kautilya.

We investigate the hypothesis that our conceptual systems provide two formally distinct ways of representing categories by investigating the manner in which lexical nominals (e.g., tree, picnic table) and phrasal nominals (e.g., black bird, birds that like rice) are interpreted. Four experiments found that lexical nominals may be mapped onto kind representations, whereas phrasal nominals map onto class representations but not kind representations. Experiment 1 found that phrasal nominals, unlike lexical nominals, are mapped onto categories whose members need not be (...) of a single kind. Experiments 2 and 3 found that categories named by lexical nominals enter into both class inclusion and kind hierarchies and thus support both class inclusion (is a) and kind specification (kind of) relations, whereas phrasal nominals map onto class representations which support only class inclusion relations. Experiment 4 showed that the two types of nominals represent hierarchical relations in different ways. Phrasal nominals (e.g., white bear) are mapped onto classes that have criteria of membership in addition to those specified by the class picked out by the head noun of the phrase (e.g., bear). In contrast, lexical nominals (e.g., polar bear) specify one way to meet the criteria specified by the more general kind concept (e.g., bear). Implications for the language–conceptual system interface, representation of hierarchical relations, lexicalization, and theories of conceptual combination are discussed. (shrink)

Five experiments provide evidence for a class of ‘dual character concepts.’ Dual character concepts characterize their members in terms of both (a) a set of concrete features and (b) the abstract values that these features serve to realize. As such, these concepts provide two bases for evaluating category members and two different criteria for category membership. Experiment 1 provides support for the notion that dual character concepts have two bases for evaluation. Experiments 2-4 explore the claim that dual character concepts (...) have two different criteria for category membership. The results show that when an object possesses the appropriate concrete features, but does not fulfill the appropriate abstract value, it is judged to be a category member in one sense but not in another. Finally, Experiment 5 uses the theory developed here to construct artificial dual character concepts and examines whether participants react to these artificial concepts in the same way as naturally occurring dual character concepts. The present studies serve to define the nature of dual character concepts and distinguish them from other types of concepts (e.g., natural kind concepts), which share some, but not all of the properties of dual character concepts. More broadly, these phenomena suggest a normative dimension in everyday conceptual representation. (shrink)

ABSTRACT This essay examines Satyajit Ray’s children’s film Goopy Gyne Bagha Byne to interrogate the ways it signals the utopian. Contending that its utopian desire manifests through the trope of wish-fulfillment, it illuminates the trope’s centrality in the film’s imagination and articulation of freedom. Moreover, the essay suggests that the film’s utopianism is also anchored in its irrealist aesthetics. Engaging with the film’s figuration of ghosts and its violation of the narrative structure of the real, the essay illuminates how these (...) formal features inform, and are informed by, a utopian desire. Furthermore, the essay notes that despite its inherent utopianism, Goopy Gyne Bagha Byne fails to resolve some of the more obdurate social contradictions in its diegetic world, especially around questions of class, gender, and caste. Arguing that these “failures” are in keeping with its utopian spirit, I suggest they draw our attention to the imperfections of our real conditions of existence and flag the limits of textual utopianism. In so doing, they refer negatively to the social field beyond pointing to the abiding importance of class struggle as the ultimate agent of transformative social change. (shrink)

Biometrics is essentially a pattern recognition system that recognizes an individual using their unique anatomical or behavioral patterns such as face, fingerprint, iris, signature etc. Recent researches have shown that many biometric traits are vulnerable to spoof attacks. Moreover, recent works showed that, contrary to a common belief, multimodal biometric systems in parallel fusion mode can be intruded even if only one trait is spoofed. However, most of the results were obtained using simulated spoof attacks, under the assumption that the (...) spoofed and genuine samples are indistinguishable, which may not be true for all biometric traits. In addition, so far vulnerability of multimodal biometric systems in serial fusion mode against spoof attacks has not been investigated. These issues raise a demand to investigate the robustness of multimodal systems under realistic spoof attacks. In this paper, we empirically investigate the performance of serial and parallel biometric fusion modes under realistic spoof attacks. Preliminary empirical results on real biometric systems made up of face, fingerprint and iris confirm that multimodal biometric systems in both fusion modes are not intrinsically robust against spoof attacks as believed so far. In particular, multimodal biometric systems in serial fusion mode can be even less robust than systems in parallel mode. We also experimentally found that incorporating the biometric sample quality in biometric fusion increases the robustness of the multimodal systems against spoof attacks. In the end, we study the trade-off between performance and robustness of the biometric systems under spoof attacks. (shrink)

IntroductionAlthough the topic of consciousness is both mysterious and controversial, psychedelic drugs are popularly believed to provide unique insights into the nature of consciousness despite a lack of empirical evidence.MethodsThis study addresses the question of whether psychedelics change the attribution of consciousness to a range of living and non-living entities. A survey was conducted in 1,606 respondents who endorsed a belief changing psychedelic experience.ResultsParticipants rated their attributions of consciousness to a range of living and non-living entities before and after their (...) psychedelic experience. Superstitious beliefs and belief in freewill were also assessed. From before the experience to after, there were large increases in attribution of consciousness to various entities including non-human primates, quadrupeds, insects, fungi, plants, inanimate natural objects, and inanimate manmade objects. Higher ratings of mystical experience were associated with greater increases in the attribution of consciousness. Moreover, the increased attributions of consciousness did not decrease in those who completed the survey years after the psychedelic experience. In contrast to attributions of consciousness, beliefs in freewill and superstitions did not change. Notably, all findings were similar when restricted to individuals reporting on their first psychedelic experience.DiscussionThis study demonstrates that, among people who reported belief-changing psychedelic experiences, attribution of consciousness to various entities increases. Future prospective psychedelic drug administration studies that control for expectancies are needed. (shrink)

Since certain temporal aspects of the relation between duties, rights, and the interests that rights protect have not been fully theorized, a puzzle arises when we come to consider whether and how entities such as members of future generations, fetuses, deceased persons, and unconscious persons are able to possess rights. This paper evolves a unified structure for attributing the ability to possess rights to such entities. It demonstrates that while, under any cogent theory of rights-attributions, rights and duties must be (...) strictly contemporaneous, the interests that rights protect need not temporally coincide with those rights.

Small and medium-sized firms form 90% of the worldwide population of businesses. However, it has been argued that given their smaller scale of operations, resource access constraints and lower visibility, smaller firms are less likely to participate in Corporate Social Responsibility (CSR) initiatives. This article examines the different economic motivations of firms with varying combinations of visibility, resource access and scale of operations. Arguments are presented to propose that in terms of visibility, resource access and operating scale, very small and (...) very large firms are equally motivated to participate in CSR. However, the motivational bases for CSR participation are likely to be different. Medium-sized firms are the least motivated. This suggests a U-shaped relationship between firm size and CSR participation. This study contributes towards resolution of the long-standing debate on the effects of firm size on CSR participation, and highlights the importance of considering configurations of firm characteristics in the study of CSR outcomes. In conclusion, cautions are raised against the broad categorization of firms, without adequate attention to the underlying dimensions of such categorizations. (shrink)

Edition of the Tibetan text of the Madhyamakārthasaṃgraha attributed to Bhāviveka (based on the Co-ne, sDe-dge, dGa’-ldan and sNar-thaṅ versions), along with an Italian translation and an introductory philosophical study.

In Āryadevapāda’s Skhalitapramathanayuktihetusiddhi we find a problematic passage in which some Cārvāka theories are expounded. The problem here lies in the fact that, according to Āryadevapāda, the Cārvākas—who did not admit rebirth—would have upheld that happiness in this life can be gained by worshipping gods and defeating demons. As the Cārvākas were materialists, the reference to gods and demons does not fit so much with their philosophical perspective. In this paper, by taking into account several passages from Pāli and Sanskrit (...) Buddhist sources, I have tried to demonstrate that Āryadevapāda is here probably following the Laṅkāvatārasūtra, where mention is made of some Lokāyatikas who are said to have been able to infatuate gods and demons. In both the Pāli Canon and the Mahāyāna sūtras, however, the term lokāyata does not refer to “materialism”. It rather conveys the meaning of “art of disputation”, and is generally used in the description of brāhmaṇas well versed in the Vedas, in the recitation of mantras and in dialectic methods in general. It is the Laṅkāvatārasūtra that introduces the idea—corroborated also by a passage from the Mahābhārata—that these brāhmaṇas, skilled in lokāyata, would have indulged in some materialistic tenet. When the two terms, Cārvāka and Lokāyata, came both to mean “materialism”, around the IV century CE, it is highly probable that non-Cārvāka thinkers and commentators—as could be the case of Āryadevapāda—had in some occasion assimilated and integrated certain points of view, originally belonging to the ancient lokāyata perspective (for instance, the references to gods and demons), into what they believed Cārvāka philosophy had to be.

Technologies for deriving human neurons in vitro have transformed our ability to study cellular and molecular components of human neurotransmission. Three groups, including our own, have recently published methods for efficiently generating human serotonergic neurons in vitro. Remarkably, serotonergic neurons derived from each method robustly produce serotonin, express raphe genes, are electrically active, and respond to selective serotonin reuptake inhibitors in vitro. Two of the methods utilize transdifferentiation technology by overexpressing key serotonergic transcription factors. The third and most recent method (...) involves differentiating induced pluripotent stem cells (iPSCs) to serotonergic neurons using developmental patterning cues. In this mini‐review, we briefly describe the developmental programs governing serotonergic specification in vivo and how they have been harnessed to achieve serotonergic differentiation in vitro. We discuss the distinct and overlapping features of the recently published methodologies and their value in the context of in vitro disease modeling.Also see the video abstract here. (shrink)

Efforts to encourage universal access to information and communication technologies have run into the problem that some individuals, for reasons of affordability, lack of awareness or preference, continue to be without subscriptions. This article examines the arguments commonly put forward in support of promoting broadband access, to determine whether they can justify universalizing access. It examines the ethical limits of government actions that encourage, enforce or coerce participation in socially beneficial programmes, while potentially overlooking consumer sovereignty and human autonomy. The (...) conclusions address how policymakers can encourage universal access to broadband, while respecting the rights of citizens. (shrink)

Ali comparative studies imply simultaneously an identity and a difference, a situation that is replete with intellectual difficulties which give rise to interminable disputes regarding whether we are talking about the same thing or different things. One may cut the gordian knot by deciding either way, but the situation would reappear again as it is bound up with the comparative perspective itself and not with any particular example of it. How long shall we go on “naming”, for the process is (...) unending and ultimately “everything is what it is. and not another thing”. Or, if we do not like “names” as they hardly give us any knowledge and if we opt for “description” which gives us “facts”, then they too are as unending as the “names”, for, as the Jains taught us long ago, they are a function of the dṛṣti that we have or the point of view that we adopt.

Emotions play a significant role in human cognitive processes such as attention, motivation, learning, memory, and decision making. Many researchers have worked in the field of incorporating emotions in a cognitive agent. However, each model has its own merits and demerits. Moreover, most studies on emotion focus on steady-state emotions than emotion switching. Thus, in this article, a domain-independent computational model of emotions for intelligent agent is proposed that have modules for emotion elicitation, emotion regulation, and emotion transition. The model (...) is built on some well-known psychological theories such as appraisal theories of emotions, emotion regulation theory, and multistore human memory model. The design of the model is using the concept of fuzzy logic to handle uncertain and subjective information. The main focus is on primary emotions as suggested by Ekman; however, simultaneous elicitation of multiple emotions is also supported by the model. (shrink)
