The author publishes the initial fragment of an unknown treatise by Leon Battista Alberti on the casting of statues written around 1455 and preserved in cod. Ottob. lat. 1870. The fragment contains a discussion on the nature of light and the element of fire.

Basilio Sabazio was the first in Italy to argue for the unity and corruptibility of either sublunar or celestial matter. In this paper new insight of his intellectual activity between Napoli and Milano is provided, and in particular his relationship with Scipione Capece, from whose letter to Giovan Francesco di Capua, Count of Palena we learn that Sabazio was an expert in philology and astronomy. The surviving part of an essay by Sabazio to the astronomer Francesco Cigalini from Como is (...) here edited with some informations about Cigalini’s reply. A newly recovered Sabazio’s astronomical work is here edited – from which his endorsement of Eraclides Ponticus’ astronomical system is evident –, as well as his Consilium to Pope Paolo III about the urgency of convening a general council.

The essay illustrates the figure of Demetrios Kavàkis Rhaoul, Byzantine official at the service of the last two Paleologue emperors and of the Despots of the Peloponnese, who was also George Gemistos Plethon’s friend and student. Two short works of his are here published for the first time, one on the Sun God and another on the classification of the religions professed by humanity, alongside two small inedited letters by Plethon. In the first of the two writings, Kavàkis clears the (...) reasons for his aversion towards any kind of religion or philosophy that places the divine beyond the visible world and that believes in the existence of an intelligible or, even worse, over-intelligible world. These ideas lead him to clash not only with Christianity, but also with Plato and with the ideas of his beloved teacher Plethon, who, however, seems to agree with him in a dream. In the second writing this peculiar solar religion is reaffirmed, against the religion of poets and the religions of transcendence, warning however that nature wants some respect for the religion of ancestors, whichever this might be, when it is functional to the life of the society and of the State.

This paper provides a historical reevaluation of the originality and implications of Avempace's critique of Aristotle's causal explanation of the motion of projectiles. It also offers a serious revision of the place which has usually been assigned to Avempace in the history of science. The views regarding projectiles defended in Avempace's Arabic commentary are in sharp opposition to the anti-Aristotelian Avempace that was known in the Medieval West through Averroes. Avempace's commentary reveals only a moderate critic of Aristotle, a critic (...) who did not, in any case, break with the master, and who, therefore, did not even go as far as Philoponus in creating a new and more profound theory of projectile motion.

This paper presents the Futurium platform used by Digital Futures, a foresight project launched by the European Commission's Directorate General for Communications Networks, Content and Technology (DG CONNECT). Futurium was initially developed with the primary purpose of hosting and curating visions and policy ideas generated by Digital Futures (Digital Futures was launched in July 2011 by DG CONNECT's Director General Robert Madelin following a prior DG CONNECT exercise called Digital Science.). However, it has turned into a platform on which to (...) experiment with new policymaking models based on scientific evidence and stakeholder participation, referred to in this paper as ‘Policy Making 3.0’. The platform hosts an online foresight toolkit to facilitate the joint creation of ideas to help design future policies. It leverages the potential of social networks, open data, semantic and knowledge mining technologies as well as participatory brainstorming techniques to engage stakeholders and harness their views and creativity to better inform policies that matter to them. The Futurium distinguishes between different variables, reflecting the emotional vs. rational mindsets of the participants, and offers the possibility to frame the engagement and co-creation process into multiple phases of a workflow. Futurium was developed to support Digital Futures, but its open architecture makes it easily adaptable to any policymaking/decision-making context where thinking ahead, participation, scientific evidence and agility are needed. Futurium is an early prototype implementation of the Policy Making 3.0 model, which is a long-term vision requiring further investigation and experimentation. The Futurium production website can be seen here: ec.europa.eu/digital-agenda/futurium. (shrink)

This article compares the political philosophies of Michael Oakeshott and Isaiah Berlin, probably the two most important political philosophers in postwar Britain, who, strangely, had very little to do with one another during their illustrious careers. The article focuses on their respective critiques of rationalism and theories of liberal pluralism, arguing that Oakeshott provides the more consistent and philosophically satisfying account in both instances.

In this detailed study of the republican tradition in the development of the Enlightenment, the central problem of utopia and reform is crystallized in a discussion of the right to punish. Describing the political situation in Europe in the seventeenth and eighteenth centuries, the author shows how the old republics in Italy, Poland and Holland stagnated and were unable to survive in the age of absolutism. The Philosophes discussed the ideal of republicanism against this background. They were particularly influenced by (...) the political and religious radicalism of John Toland, which had survived the English Restoration and was then reaching Europe. Professor Venturi traces the debate on the penal laws and the attempt to relate utopian ideas of society to the practical problem of dealing with man in society, which culminated in the assertion by many Philosophes that an unjust social system necessitated harsh penal laws, thereby rejecting the possibility of reform.

An examination of new forms of alienation in our never-off, plugged-in culture—and a clarion call for a “conspiracy of estranged people.” We can reach every point in the world but, more importantly, we can be reached from any point in the world. Privacy and its possibilities are abolished. Attention is under siege everywhere. Not silence but uninterrupted noise, not the red desert, but a cognitive space overcharged with nervous incentives to act: this is the alienation of our times... —from The (...) Soul at Work Capital has managed to overcome the dualism of body and soul by establishing a workforce in which everything we mean by the Soul—language, creativity, affects—is mobilized for its own benefit. Industrial production put to work bodies, muscles, and arms. Now, in the sphere of digital technology and cyberculture, exploitation involves the mind, language, and emotions in order to generate value—while our bodies disappear in front of our computer screens. In this, his newest book, Franco “Bifo” Berardi—key member of the Italian Autonomist movement and a close associate of Félix Guattari—addresses these new forms of estrangement. In the philosophical landscape of the 1960s and 1970s, the Hegelian concept of alienation was used to define the harnessing of subjectivity. The estrangement of workers from their labor, the feeling of alienation they experienced, and their refusal to submit to it became the bases for a human community that remained autonomous from capital. But today a new condition of alienation has taken root in which workers commonly and voluntarily work overtime, the population is tethered to cell phones and Blackberries, debt has become a postmodern form of slavery, and antidepressants are commonly used to meet the unending pressure of production. As a result, the conditions for community have run aground and new philosophical categories are needed. The Soul at Work is a clarion call for a new collective effort to reclaim happiness. The Soul at Work is Bifo's long overdue introduction to English-speaking readers. This Semiotext edition is also the book's first appearance in any language. (shrink)

Teachers are necessarily free. The present article discusses the dual meaning of this necessity. The first meaning relates to freedom as an inevitable aspect of the actual reality in the classroom ; the second to teachers’ freedom as the ideal condition, or a prerequisite for optimal teaching. Existentialist philosopher Jean-Paul Sartre argued that human beings are “condemned to be free” and demanded that freedom be considered an imperative value. Philosopher of education Joseph Schwab, who analysed the practical nature of teaching, (...) concluded that teachers make choices every minute in the classroom, and demanded that their autonomy be expanded. This article identifies parallels between these two philosophical moves and suggests complementing features. Sartre adds universal depth to Schwab’s portrait of teachers, proving them to be an extreme expression of the human condition. Schwab provides Sartre’s analysis with concrete validation and practical suggestions for implementation. Combining these two approaches can further establish the importance of teacher autonomy and offer a unique conceptualisation of teacher agency as a partial response to the crisis of education in the postmodern era.

Can psychology contribute in some way to the approach to the fundamental questions of life? Psychology can be and indeed often is seen and used as a technique. In reality, every psychology carries in itself the seeds, more or less developed, of an anthropology, just as every anthropology cannot but have a pedagogical/psychological component. Without claiming to be comprehensive, the article raises some questions concerning the unavoidable integration of psychological aspects with the fundamental dimensions of being, such as the truth (...) to be known, the good to be worked for, and the unity or harmony found at the basis of human motivations. All this cannot disregard the pedagogical dimension/mission, recalling that the question is not 'what' or 'if' but rather 'which one' and 'how'. (shrink)

By a theorem of R. Kaye, J. Paris and C. Dimitracopoulos, the class of the Πn+1-sentences true in the standard model is the only consistent Πn+1-theory which extends the scheme of induction for parameter free Πn+1-formulas. Motivated by this result, we present a systematic study of extensions of bounded quantifier complexity of fragments of first-order Peano Arithmetic. Here, we improve that result and show that this property describes a general phenomenon valid for parameter free schemes. As a consequence, we obtain (...) results on the quantifier complexity, finite axiomatizability and relative strength of schemes for Δn+1-formulas. (shrink)

The concept of scaffolding has wide resonance in several scientific fields. Here we attempt to adopt it for the study of development. In this perspective, the embryo is conceived as an integral whole, comprised of several hierarchical modules as in a recurrent circularity of emerging patterns. Within the developmental hierarchy, each module yields an inter-level relationship that makes it possible for the scaffolding to mediate the production of selectable variations. A wide range of genetic, cellular and morphological mechanisms allows the (...) scaffolding to integrate these modular variations into a functionally coordinate unit. A genetic scaffolding accounts for the inherited invariance of pattern formation during the embryo’s growth. At higher level, cells behave as agents endowed with the capacity to interpret any scaffolding variation as signs. The full hierarchy of a multi-level scaffolding is eventually attained when the embryo acquires the capacity to impose a number of developmental constraints on its constituting parts in a top-down direction. The acquisition of this capacity allows a semiotic threshold to emerge between the living cellular world and the underlying non-living molecular world. As this boundary is gradually defined during development, cells enter into new functional relationships, while, at the same time, are relieved from their physical determinism. The resulting constraints can thus become the driving forces that upgrade embryonic scaffolding from the simple molecular signalling to the complexity of sign recognition proper of a cellular community. In this semiotic perspective, the apparent goal directness of any developmental strategy should no longer be accounted for by a predetermined genetic program, but by the gradual definition of the relationships selected amongst the ones historically explored.
