We offer a formal treatment of the semantics of both complete and incomplete mistrustful or distrustful information transmissions. The semantics of such relations is analysed in view of rules that define the behaviour of a receiving agent. We justify this approach in view of human agent communications and secure system design. We further specify some properties of such relations.

This paper presents a systematic discussion, mainly for non-economists, on economic approaches to the concept of sustainable development. As a first step, the concept of sustainability is extensively discussed. As a second step, the argument that it is not possible to consider sustainability only from an economic or ecological point of view is defended; issues such as economic-ecological integration, inter-generational and intra-generational equity are considered of fundamental importance. Two different economic approaches to environmental issues, i.e. neo-classical environmental economics and ecological (...) economics, are compared. Some key differences such as weak versus strong sustainability, commensurability versus incommensurability and ethical neutrality versus different values acceptance are pointed out. (shrink)

This paper proposes a critical analysis of that interpretation of the Nāgārjunian doctrine of the two truths as summarized—by both Mark Siderits and Jay L. Garfield—in the formula: “the ultimate truth is that there is no ultimate truth”. This ‘semantic reading’ of Nāgārjuna’s theory, despite its importance as a criticism of the ‘metaphysical interpretations’, would in itself be defective and improbable. Indeed, firstly, semantic interpretation presents a formal defect: it fails to clearly and explicitly express that which it contains logically; (...) the previously mentioned formula must necessarily be completed by: “the conventional truth is that nothing is conventional truth”. Secondly, after having recognized what Siderits’ and Garfield’s analyses contain implicitly, other logical and philological defects in their position emerge: the existence of the ‘conventional’ would appear—despite the efforts of semantic interpreters to demonstrate quite the contrary—definitively inconceivable without the presupposition of something ‘real’; moreover, the number of verses in Nāgārjuna that are in opposition to the semantic interpretation (even if we grant semantic interpreters that these verses do not justify a metaphysical reconstruction of Nagarjuna’s doctrine) would seem too great and significant to be ignored.

Symmetries play a major role in physics, in particular since the work by E. Noether and H. Weyl in the first half of last century. Herein, we briefly review their role by recalling how symmetry changes allow to conceptually move from classical to relativistic and quantum physics. We then introduce our ongoing theoretical analysis in biology and show that symmetries play a radically different role in this discipline, when compared to those in current physics. By this comparison, we stress that (...) symmetries must be understood in relation to conservation and stability properties, as represented in the theories. We posit that the dynamics of biological organisms, in their various levels of organization, are not just processes, but permanent (extended, in our terminology) critical transitions and, thus, symmetry changes. Within the limits of a relative structural stability (or interval of viability), variability is at the core of these transitions. (shrink)

What is the truth of the unconscious? _Truth and the Unconscious in Psychoanalysis _explores the intersection of these two concepts within a Bionian framework. Giuseppe Civitarese maps out the unconscious in psychoanalysis, and focuses on the differences between the Freudian, Kleinian, Bionian and Lacanian schools of thought on this topic, as well as drawing on findings from neuroscience. The book explores topics including the inaccessibility of the unconscious, dreams, body issues, issues of personality, the influence of field theory and (...) the clinical implications of this theorising. It contains innovative comparison between Freudian metapsychology and the Bionian theory on thinking, and novel use of Bion's hallucinosis as an important new technical tool. An internationally recognised author, Civitarese provides fresh ideas throughout on a challenging subject, supported with vivid clinical material. _Truth and the Unconscious in Psychoanalysis _will be of interest to anyone following the growing post-Bionian movement within contemporary psychoanalysis, enabling them to familiarize themselves with some of the most important current issues in psychoanalytic research. _Truth and the Unconscious in Psychoanalysis _will appeal to psychotherapists, psychologists and psychoanalysts, as well as undergraduate and postgraduate students studying in the field.

Central figures in the phenomenological tradition, such as Aron Gurwitsch, Jean-Paul Sartre, and Maurice Merleau-Ponty, drew extensively on gestalt psychology in their writings. The dialogue between phenomenology and psychology they began continues today in the field of embodied cognitive science. We take up this conversation starting from Aron Gurwitsch’s rich phenomenological analysis of the perception of the cultural world. Gurwitsch’s phenomenological descriptions of the perception of the cultural world bear a striking resemblance to work in embodied cognitive science that takes (...) its inspiration from Gibson’s ecological psychology. Gibson coined the term “affordance” to refer to the possibilities for action that can be directly perceived by persons [Gibson 1979]. However, Gibson from his earliest writings made a distinction between a universal, strictly individual and nonsocial form of perception and a perception of the world that was subject to social and cultural influences. We use Gurwitsch to argue against Gibson’s individualist understanding of direct perception. Each affordance that can be selected as an object of perception refers to a wider sociocultural context, which Gurwitsch called an “order of existence”. We end our paper by taking up the question of the relation of phenomenological description of the perceptual world and explanations of perceptual experience provided by embodied cognitive science.

The virtuous character and the ethical agent represent mutually inclusive terms, neither of which independently, in the Aristotelian tradition, is considered an innate quality. Virtues, if not innate, are contingent; but what makes each instantiation recognisably general? Normative ethics in this sense is a dynamic process and similarly process philosophy is based on the principle that existence is dynamic and that it should be the primary focus of any philosophical account of reality. I argue that the transformative process is equally (...) as important as the end result of realising the virtuous dispositional traits. An important criticism of virtue ethics is the focus on character and not rules such as industry practices and codes found in the professions. The criticism however is less worrisome than usually accepted. The reasoning herein developed to overcome this criticism rests on the presupposition that no one exists in isolation and virtues are developed in a social context and not simply given. Using process philosophy as a methodological approach to examine virtue ethical agency and the transformative process involved in its realisation elicits insights that allow the conceptual development of a more robust account of virtue ethics. I extend this nuanced rendition, in ways already commenced by others, into areas of organisational, environmental and intergenerational ethics. (shrink)

L'Autore ritiene che la critica vichiana delle borie non si riferisca solo a nazioni, culture e teorie filosofico-teologiche concentrate a discutere sull'origine oscura e favolosa dei tempi e sulla relazione tra storia sacra e storie profane. Ma è anche un dispositivo etico-filosofico che invita l'umanità, ormai al culmine del processo di incivilimento, a guardarsi da ogni forma di boria delle nazioni , così come da ogni manifestazione boriosa da parte dei dotti . The author argues that Vico's critique of conceit (...) does not refer only to nations and cultures, and to philosophical-theological theories focused on origins in ancient and mythical times and on the relationship between sacred and profane history. Vico's critique is also an ethical-philosophical device that invites humanity, now at the height of the civilizing process, to guard against any form of conceit by nations , as well as any self-important manifestations by intellectuals.

In this article the authors intend to present a very important topic of the geometry of space: the polyhedra. After having introduced their definition, their presence will be shown in nature, in everyday life and in art, starting from ancient Greece up to the present day. First of all, we will deal with regular polyhedra; subsequently we will introduce the important family, especially in the applications, of the Archimedean polyhedra. Finally, the interesting Goldberg polyhedra will be presented.
