Two recent hypotheses have proposed that non‐green plant colouration evolved as a defence against herbivores, either as protective colouration promoting handicap signals indicating plant fitness or by undermining their crypsis. The handicap hypothesis posits a co‐evolutionary process between plants and herbivores, whereas the anti‐crypsis hypothesis suggests that an arms race between insects and plants is the evolutionary mechanism. Both explanations assume that insects are the evolutionary origin causing plants' colouration. Here, we propose a different hypothesis, termed the “Defence Indication hypothesis”. (...) This idea focuses on the multiple protective functions of anthocyanins and carotenoids as pigments, and suggests that plant colouration evolved primarily in response to various stressors. Because pigments and defensive compounds share a common biosynthesis, the production of pigments also provides elevated defensive strengths against herbivores, a process termed priming. In effect, the Defence Indication hypothesis predicts that pleiotropic effects of the pigments and, more generally, plants' shared defence responses, explain why insects might react to plant colouration.

Reflective equilibrium (RE) is often regarded as a powerful method in ethics, logic, and even philosophy in general. Despite this popularity, characterizations of the method have been fairly vague and unspecific so far. It thus may be doubted whether RE is more than a jumble of appealing but ultimately sketchy ideas that cannot be spelled out consistently. In this paper, we dispel such doubts by devising a formal model of RE. The model contains as components the agent’s commitments and a (...) theory that tries to systematize the commitments. It yields a precise picture of how the commitments and the theory are adjusted to each other. The model differentiates between equilibrium as a target state and the dynamic equilibration process. First solutions to the model, obtained by computer simulation, show that the method allows for consistent specification and that the model’s implications are plausible in view of expectations on RE. In particular, the mutual adjustment of commitments and theory can improve one’s commitments, as proponents of RE have suggested. We argue that our model is fruitful not only because it points to issues that need to be dealt with for a better understanding of RE, but also because it provides the means to address these issues.

When perceiving a face, we can easily decide whether it belongs to a human or non-human primate. It is thought that face information is represented by neurons in the macaque temporal cortex. However, the precise encoding mechanisms used by these neurons remain unclear. Here we use face stimuli of humans, monkeys and monkey-human hybrids (morphs) to gain a better understanding of these mechanisms, in particular of the categorization of faces into different species, and how learning affects representation of these stimuli.

Investigating the terms such as 'Form' or 'idea', 'essence' or 'being', 'participation', 'presence' and 'community', this book aims to determine the precise historical and philosophical contexts on which Plato drew in the formulation of his thoughts.

The article tries to prove that the famous formula "epekeina tês ousias" has to be understood in the sense of being beyond being and not only in the sense of being beyond essence. We make hereby three points: first, since pure textual exegesis of 509b8–10 seems to lead to endless controversy, a formal proof for the metaontological interpretation could be helpful to settle the issue; we try to give such a proof. Second, we offer a corollary of the formal proof, (...) showing that not only self-predication of the form of the Good, but of any form is not possible, that is: no form of F has the form of F. Third, we apply Spinoza’s distinction between an ens imaginarium and a chimaera to Plato’s Idea of the Good. (shrink)

Connectedness is a significant element of sociality that occurs not only ideally and ‘leiblich’, but also consists of a material dimension. This is established through the materiality of the human body and points beyond it at the same time. The material aspect of connectedness is not simply social but has a social meaning nonetheless: Materiality has an impact on society and on the quality of human coexistence with the environment. To be able to describe this aspect, we use approaches of (...) feminist (neo-)materialisms. First, a neo-materialist perspective on subjectivity is developed, which, in addition to the immaterial aspects of the social, is also able to grasp the dependence of the development of human bodies on their environment. Connectedness as a material-discursive phenomenon adds a neo-materialist dimension to the established ‘phenomenological’ interpretation of the resonance concept that integrates interactions of repulsion or alienation by understanding feelings of alienation, rejection, or the silencing of the world-relationship as well as a resonant world-relationship always also as agentic cuts of the LeibKörper.

El presente trabajo explora las conceptualizaciones actuales de la capacidad de resistencia que se aplican a personas con habilidades-diversas. El concepto de ‘ableísmo’ es presentado y se demuestra su utilidad como un lente analítico. Los resultados indican que un enfoque ecológico a la capacidad de resistencia representa un problema para el avance de los derechos de las personas con habilidades diversas. En concreto, la presencia de asunciones y lenguaje ‘ableístas’ demuestran una continua necesidad de examen crítico de las políticas relacionadas (...) con la capacidad de resistencia y su capacidad para incorporar a la población con habilidades diversas. Sugerimos que una ética feminista del cuidado de personas con habilidades diversas contribuye a la comprensión de la capacidad de resiliencia, promoviendo una agenda positiva de los derechos de las personas con habilidades diversas y dando una dirección positiva para políticas en esta área. Los resultados seguramente ayudaran a hacer frente a las lagunas existentes en la literatura de este tema, y serán de gran importancia para los responsables de políticas, investigadores, y la población con habilidades diversas.

The contributors to The Moral of the Story, all preeminent political theorists, are unified by their concern with the instructive power of great literature. This thought-provoking combination of essays explores the polyvalent moral and political impact of classic world literatures on public ethics through the study of some of its major figures-including Shakespeare, Dante, Cervantes, Jane Austen, Henry James, Joseph Conrad, Robert Penn Warren, and Dostoevsky. Positing the uniqueness of literature's ability to promote dialogue on salient moral and intellectual virtues, (...) editor Henry T. Edmonson III has culled together a wide-ranging exploration of such fundamental concerns as the abuse of authority, the nature of good leadership, the significance of "middle class virtues" and the needs of adolescents. This collection reinvigorates the study of classic literature as an endeavor that is not only personally intellectually satisfying, but also an inimitable and unique way to enrich public discourse.

Mitchell Greenʼs conception of the thesis of Literary Cognitivism states that literary fiction can be a source of knowledge that depends crucially on its being fictional. By a modal argument the authors show that the criterion of fictionality cannot be crucial to the epistemic value of literary fiction. Rather, it lays in a certain kind of distance, e.g. a temporal, cultural, or interpersonal one. This will be motivated by drawing parallels to Gadamerʼs hermeneutics, especially his conception of fusion of horizons. (...) In doing so, we agree with Green’s characterisation of knowledge that can be gained from engaging with literary fiction, but present a different approach to the source of this knowledge. At the same time, this approach enables us to extend the epistemic value of literary fiction both quantitatively and qualitatively. (shrink)

Diz o ditado que "quem não gosta de samba, bom sujeito não é: ou é ruim da cabeça ou doente do pé". Os filósofos tradicionalmente são doentes do pé e muitos deles certamente são ruins da cabeça. Isso parece tornar o tema desse livro pouco viável. Entretanto, tentamos mesmo assim. Afinal gente ruim da cabeça também é inconsequente. Na verdade, esse livro é a continuação do desejo compartilhado por seus diversos autores de aproximar a filosofia da cultura brasileira. E nada (...) melhor para tornar esse diálogo palpável do que o motivo fornecido pelo samba. Afinal, ele é uma de nossas manifestações nacionais mais típicas, difundidas e que tem sobrevivido a várias transformações ao longo do tempo. Através desse livro, esperamos ter nos tornado menos doentes do pé e menos ruins da cabeça -- apesar de quase todos gostarem de samba. (shrink)

Brain-computer interfaces are envisioned to enable new abilities of action. This potential can be fruitful in particular when it comes to restoring lost motion or communication abilities or to implementing new possibilities of action. However, BCIs do not come without presuppositions. Applying the concept of ability expectations to BCIs, a wide range of requirements on the side of the users becomes apparent. We examined these ability expectations by taking the example of therapeutic BCI users who got enrolled into BCI research (...) studies due to particular physical conditions. Some of the expectations identified are quite explicit, like particular physical conditions and BCI “literacy”. Other expectations are more implicit, such as motivation, a high level of concentration, pain tolerance, emotion control and resources. These expectations may produce a conception of the human and a self-understanding among BCI users that objectify the body in favour of a brain-centred, cerebral notion of the subject which also plays its part in upholding a normality regime.

If we want to understand how extremist group ideologies are established, we have to comprehend the social processes which form the basis of the emergence and distribution of such beliefs. In our chapter, we present an innovative approach to examining these processes and explaining how they function: with the method of computer-based simulation of opinion formation, we develop heuristic explanatory models which help to generate new and interesting hypotheses. The focus is thereby not on individuals and their idiosyncrasies but on (...) the dynamic mutual adaptation of beliefs in a group. These dynamics can produce an incremental establishment of “charismatic” opinion leaders and an increasing radicalization and alienation. A prototype of such a simulation model has produced promising first results which are presented and discussed. (shrink)

New Essays on Plato assembles nine original papers on the language and thought of the Athenian philosopher. The collection encompasses issues from the Apology to the Laws and includes discussions of topics in ethics, political theory, psychology, epistemology, ontology, physics and metaphysics, and ancient literary criticism. The contributions by an international team of scholars represent a spectrum of diverse traditions and approaches, and offer new solutions to a selection of specific problems. Themes include the Happiness and Nature of the Philosopher-Kings, (...) Law and Justice, the Tripartition of the Soul, Appearance and Belief, Conditions of Recognition, Ousia or What Something Is, the Reality of Change and Changelessness, Time and Eternity, and Aristotle on Plato.

Over evolutionary time, humans have developed a selective sensitivity to features in the human face that convey information on sex, age, emotions, and intentions. This ability might not only be applied to our conspecifics nowadays, but also to other living objects (i.e., animals) and even to artificial structures, such as cars. To investigate this possibility, we asked people to report the characteristics, emotions, personality traits, and attitudes they attribute to car fronts, and we used geometric morphometrics (GM) and multivariate statistical (...) methods to determine and visualize the corresponding shape information. Automotive features and proportions are found to covary with trait perception in a manner similar to that found with human faces. Emerging analogies are discussed. This study should have implications for both our understanding of our prehistoric psyche and its interrelation with the modern world. (shrink)

In this article, we explore why solidarity has not worked according to expectation in EU migration and asylum law and why it is unlikely to work in the future. First, we consider discourses of burden-sharing and solidarity in EU law from the 1990s up to the Lisbon Treaty in 2009 to identify emergent path dependencies. This period saw the introduction of primary law provisions on solidarity, such as Article 80 TFEU, as French and Dutch electorates had rejected a European constitution. (...) Second, we perform an analysis of Article 80 through the conceptual history of solidarity, in particular, the dominant Roman law tradition of obligation in solidum and the French tradition of solidarism. We submit that the term ‘solidarity’ is actually a misnomer: already on structural grounds, Article 80 should be read as an alliance clause, countering a threat of irregular immigration. Third, we find that the practice under Article 80 as it develops during the period between 2015 and the 2020 European Commission Pact on Migration and Asylum corroborates this finding. Overall, we find that the concept of solidarity in EU asylum and migration law engenders outcome expectations that it cannot deliver as the defence alliance it is. (shrink)

Seit Beginn der frühen Neuzeit ist das naturwissenschaftliche Verfahren maßgeblich durch ein neues Konzept geprägt: das Konzept des experimentellen, gestalterischen Eingriffs in die Natur. Es geht nun nicht mehr darum, eine Geschichte der "freien und ungebundenen Natur" (Bacon) zu erzählen, die in ihrem eigenen Lauf belassen und als vollkommene Bildung betrachtet wird. Es geht vielmehr darum, der "gebundenen und bezwungenen Natur" (Bacon) vermittels der experimentellen Tätigkeit des Menschen die Geheimnisse zu entreißen. Diese technisch-praktische Konzeption grenzt sich explizit von den klassischen (...) kontemplativen Wissenschaftsvorstellungen der Antike ab. Wie es Kant paradigmatisch in Bezug auf Bacon formuliert hat, ist diese "Revolution der Denkart" maßgeblich durch ein gewandeltes Verständnis des Verhältnisses des Menschen zur Natur geprägt. Der Mensch als Experimentator hat für Kant nicht mehr die "Qualität eines Schülers", der sich passiv von der Natur belehren läßt und an ihrem "Leitbande" (Kant) gegängelt wird. Seine neu gewonnene Autorität verleiht ihm vielmehr den Status eines Richters, der nun die Natur nötigen kann, auf gestellte Fragen zu antworten. Die Laborforschung der modernen Naturwissenschaft ist von den Formen der alten Naturwissenschaft so weit entfernt, daß sie den Vorwurf auf sich zog, sie untersuche Artefkakte, aber nicht Natur. Die grundlegenden Theorien über Natur können in der Regel nur unter den künstlichen Bedingungen des Labors aufgestellt werden. Daraus darf aber nicht geschlossen werden, die anhand von Laborphänomenen aufgestellten und getesteten Theorien handelten nicht von der Natur außerhalb der Labore. Aber ihrer exakten und detaillierten Anwendung auf Prozesse außerhalb der Labore stehen eine Fülle von Schwierigkeiten entgegen. Insofern markiert das Labor sehr wohl eine Grenze exakter Naturforschung, die für den Umgang der wissenschaftlich-technischen Zivilisation mit der Natur wichtige Konsequenzen hat. (shrink)
