Previous examinations of the scope of moral concern have focused on aggregate attributions of moral worth. However, because trade‐offs exist in valuing different kinds of entities, tabulating total amounts of moral expansiveness may conceal significant individual differences in the relative proportions of moral valuation ascribed to various entities. We hypothesized that some individuals (“tree‐huggers”) would ascribe greater moral worth to animals and ecosystems than to humans from marginalized or stigmatized groups, while others (“human‐lovers”) would ascribe greater moral worth to outgroup (...) members than to the natural world. Additionally, because moral valuation is often treated as being zero‐sum, we hypothesized that there would be no difference in aggregate levels of moral concern between tree‐huggers and human‐lovers. Finally, because attributions of mental capacities substantially contribute to moral valuation, we predicted that tree‐huggers and human‐lovers would show different patterns of mind attribution for animals versus humans. Three studies (N = 985) yielded evidence in support of our hypotheses. First, over one‐third of participants valued nature over outgroups. Second, extending moral value to animals and nature was not indicative of more expansive moral concern overall; instead, tree‐huggers and human‐lovers were identical in their aggregate ascriptions of moral worth. Third, tree‐huggers had relatively amplified tendencies to attribute mental capacities to animals and relatively reduced tendencies to attribute mental capacities to outgroup members—thus having elevated rates of both anthropomorphism and dehumanization. These findings necessitate a reconceptualization of both the extension of moral worth and the attribution of minds. (shrink)

There are many things, ideas, and entities that we encounter every single day that can be described as vague, that is, one cannot precisely classify them as members of a specific class of objects. Although many hold the opinion that vagueness is either a deficiency of spoken languages or something that exists merely because we do not have all relevant details, a third group of people assume that vagueness is something real. This simply means that objects, including living beings, are (...) vague. But if vagueness is a real thing, why do people ignore it when trying to explain a natural phenomenon, a syndrome, etc.? The reason is that people have a deep respect for pure, abstract objects with exact properties. But this has a negative effect on our understanding of our cosmos. Therefore, we investigate how vagueness really affects exact sciences and how the incorporation of vagueness will improve our understanding of our world. (shrink)

The discrete Deffuant model and its alternatives is a family of stochastic spatial models for the dynamics of binary opinions on f issues. Another parameter is also incorporated that prevents interaction between two agents whenever their opinion profiles are at a Hamming distance greater than the confidence threshold θ. By numerical simulations, it was conjectured in (Adamopoulos and Scarlatos, Complexity 2012, 17, 43) that one‐dimensional models exhibit a phase transition at a critical value θ critical approximately equal to f/2. We (...) report on recent mathematical results on this problem that originates from the community of complex systems. © 2016 Wiley Periodicals, Inc. Complexity 21: 437–439, 2016. (shrink)

The book provides the first full length exploration of fuzzy computability. It describes the notion of fuzziness and present the foundation of computability theory. It then presents the various approaches to fuzzy computability. This text provides a glimpse into the different approaches in this area, which is important for researchers in order to have a clear view of the field. It contains a detailed literature review and the author includes all proofs to make the presentation accessible. Ideas for future research (...) and explorations are also provided. Students and researchers in computer science and mathematics will benefit from this work. (shrink)

The book starts with the assumption that vagueness is a fundamental property of this world. From a philosophical account of vagueness via the presentation of alternative mathematics of vagueness, the subsequent chapters explore how vagueness manifests itself in the various exact sciences: physics, chemistry, biology, medicine, computer science, and engineering.

Although Hegel'sLectures on the History of Philosophywas teaching material intended for students and published posthumously, it would be wrong to regard this work as irrelevant to his philosophical project. In his introduction to theLectures, Hegel emphasised that the history of philosophy should not be treated as a mere accumulation of opinions, or as a random collection of correct and incorrect views according to some later standards. The history of philosophy, just like art, religion andRecht, reflects the necessary logical determinations of (...) the Idea, and in this sense it should be studied with the intent of revealing those determinations. Hegel, of course, intended his project to be sufficiently established through thePhenomenologyand theLogicwithout the need to resort to any historical manifestations of culture. However, his interpretation of the history of philosophy does reveal his own philosophical agenda more straightforwardly than the ahistorical complex accounts of his other major works.Hegel's intention was to present the development of the history of philosophy as a reflection of the development of the Idea. Therefore, one would assume that the further we go back in time, we would find philosophers whose doctrines were less mature and more distant from Hegel's own conception of philosophy. However, Hegel seems to have singled out a few favourite philosophers, to whom he did not hesitate to attribute insights that could not possibly have been developed at the time, according to his pre-conceived pattern of development. One famous example was Aristotle, whom he credited with the conception of a Reason that becomes its own object, i.e., Reason which is ‘in and for-itself.’ A philosopher belonging to the ‘objective’ stage of the spirit could not normally have achieved such a conception.

While trying to preserve the autonomy of their playful activity consisting in a game of ‘questioning and answering’, the Gymnosophists defy Alexander the Great and, more importantly, go against their own chances of survival (since giving a wrong answer to the king’s question amounts to losing their life). Thankfully, we do not need to face such dilemmas when philosophising with children. Nevertheless, the Gymnosophists’ example helps construct a notion of philosophy for/with children as an autonomous playful activity that albeit (implicitly) (...) purposive it is, however, without (explicit) purpose (something akin to Kant’s aesthetic judgement). Alluding to an Aristotelian sense of ‘telos’ in its connection with Platonic ‘paideia’ I understand philosophy for/with children as an activity that we carry out for its own sake. This does not mean that we are to abolish elements such as antagonism, competition, excellence, etc.―there is no question: the competitive element is there. But what does it mean? We could fix its meaning according to a purpose (we compete to excel or persuade and win) or we might entertain the idea of keeping its meaning rather vague or undetermined, implicit. (shrink)

Trail-And-Error machines have been proposed by Hintikka and Mutanen as an alternative formulation of the notion of computation. These machines extend the capabilities of the Turing machine and widen the theory of computation.

Vagueness is a linguistic phenomenon as well as a property of physical objects. Fuzzy set theory is a mathematical model of vagueness that has been used to define vague models of computation. The prominent model of vague computation is the fuzzy Turing machine. This conceptual computing device gives an idea of what computing under vagueness means, nevertheless, it is not the most natural model. Based on the properties of this and other models of vague computing, an attempt is made to (...) formulate a basis for a philosophy of a theory of fuzzy computation. (shrink)

Generally, an object is vague when its properties cannot precisely defined. The ontic view of vagueness is the idea that vagueness is a fundamental property of Nature. This simply means that everything is vague: animals, plants, molecules, atoms, etc. Furthermore, if atoms and molecules are vague, then the subject matter of chemistry is vague. However, we first need to understand why molecules and atoms are vague.

We investigate the one-dimensional dynamics of alternatives of the Axelrod model (ξ(t)), where t is the time, with k binary features and confidence parameter ε = 0, 1,…, k. Simultaneously, the simple Axelrod model is also critically examined. Specifically, for small and large ε, simulations suggest that the convergent model (ξ(t)) is emulated by a corresponding attractive model (η(t)) with the same parameters (conditional on bounded confidence). (η(t)) is more mathematically tractable than (ξ(t)), and the very definitions of the two (...) qualitative behaviors of cyclic particle systems (fluctuation and fixation) are applicable in special cases. Moreover, we observe a complementarity: for not too small k and equation image, (η(t)) fixates (each site has a final type independent of the possibly infinite size of the lattice), whereas (ξ(t)) fluctuates (each site changes type at arbitrarily larger times t as the size of the lattice increases).

Ideograms have great communicative value. They refer to concepts in a simple manner, easing the understanding of related ideas. Moreover, ideograms can simplify the often cumbersome notation used in the fields of Physics and physical Chemistry. Nonetheless only a few ideograms—like \ and Å—have been defined to date. In this work we propose that the scientific community follows the example of Mathematics—as well as that of oriental languages—and bestows a more important role upon ideograms. To support this thesis we propose (...) ideograms for essential concepts in Physics and Chemistry. They are designed to be intuitive, and their goal is to make equations easier to read and understand. Our symbols are included in a publicly available package. (shrink)

According to LAMPAKIS (L.), the main purpose of this book is to offer a detailed biography of Georgios Pachymeres as well as an assessment of his works (p. 9). Unfortunately, it falls far short of achieving either of these objectives. First, the choice of wording – “Introductory essay” – in the title is somewhat infelicitous. The meaning of “essay” in modern Greek is vague, to say the least, and few would apply this term to a book which, in essence, is (...) an unnecessarily long compilation of the known facts about Pachymeres' life and works. Only an attempt by the author to interpret the thought of Pachymeres or to place his work in the broader historical context of his times would have convincingly justified the term “essay” for this particular monograph.

The present contribution engages with two representative examples of middle-Byzantine ekphraseis, Photios’ description of the Virgin of the Pharos and Leo VI’s account of the church founded by Stylianos Zautzes. It aims at showing how these texts suggest modes of viewing the sacred space and decoration that pose, more than settle, questions about images and pictures, their intended function, significance and impact within their specific cultural frames of reference. Far from being neutral and disengaged, these verbal representations have a (...) specific agenda, which inflects the audience’s perception and interpretation of the decorated church space. Comparisons with coeval monumental evidence are also offered, in order to analyze textual and visual developments in parallel. (shrink)
