In this article, the cosmological positions of George of Trebizond are regrouped and an attempt to evaluate his offer to the philosophy of nature in the Renaissance is presented. George of Trepizond dedicated a huge part of his work to the philosophical and scientific study of the world; he also renewed the way the Greek letters are studied and used.

: To honor Bernard Goldstein, this article highlights in the "Defense of Theon against George of Trebizond" by Regiomontanus (1436-1476) themes that resonate with leading strands of Goldstein's scholarship. I argue that, in this poorly-known work, Regiomontanus's mastery of Ptolemy's mathematical astronomy, his interest in making astronomy physical, and his homocentric ideals stand in unresolved tension. Each of these themes resonates with Gold- stein's fundamental work on the Almagest, the Planetary Hypotheses, and al-Bitruji's Principles of Astronomy. I flesh (...) out these tensions with an intriguing interpretation of the history of astronomy, in which Regiomontanus contrasts the two-dimensional "eccentric astronomy" attributed to the Almagest and the Arabs with the three-dimensional spheres of the "later" astronomers. A similar contrast reappears when Regiomontanus portrays as a "fictitious art" an astronomy that does not go beyond the accommodation of computations to the appearances. To conclude, I use Regiomontanus's expression to reinstate (pace Goldstein and Barker in this journal, 1998) fictionalism as an actor's category in Osiander and sixteenth-century astronomy. (shrink)

Georgius Trapezuntius Cretensis (or George of Trebizond) (1396-1472), an eminent humanist scholar who immigrated to Italy from Crete, is well appreciated for his translations, commentaries and treatises on philosophy, rhetoric and science. While there is a good deal of scholarship on Byzantine scholars in the Italian Renaissance, the topic of their contribution to mathematics and science in general has not to date been thoroughly addressed. This paper purports to fill this lacuna. On the basis of major evidence, I (...) will attempt to show the way Trapezuntius treated mathematics and physical sciences in order to serve his personal goals in the mid 15th century. (shrink)

In this article the views of George of Trebizond on death are regrouped and presented as they were expressed in various of his works over a long period. From their study, their dependence of classical Greek philosophy is demonstrated and his overall turn from Neo-Platonism to Aristotelianism is also adequately proved.

Testimonies of Platonic Tradition' is, in a way, a continuation of Konstantinos Staikos's recent publication 'Books and Ideas: The Library of Plato and the Academy' (2013). It deals with questions of transmission and classification of Plato's Dialogues from the philosopher's own age down to the 16th century, that is, with the fate of the Platonic corpus. As the chronicle of this journey unfolds, readers will be able to follow the foundation of philosophical schools whose teaching was based on Platonic theories (...) and concepts, in East and West. They will also obtain an overview of the works of commentary and annotation of Plato's works, composed by Greek, Roman, Byzantine, Latin and Arab authors in order to elucidate the philosopher's thought. The books makes clear the importance of 'Timaeus' from antiquity onwards, as this work became the bible of Platonism ever since Chalcidius paraphrased the dialogue into Latin and offered a classification of its subjects into categories. In addition, mention is made of the translation of 'Timaeus' and 'Parmenides' into Latin by the Greeks Henry Aristippus and George of Trebizond; the publication of the Latin translation of the philosopher's 'Complete Works' by Marsilio Ficino and the part played by the Platonic Academy of Florence in further transmitting the philosophy of Plato. The text also describes how Marcus Musurus prepared his 'editio princeps' of Plato's complete works and finally deals with the historical period when the debate over the primacy of Plato or Aristotle broke out.

Bessarion’s major philosophical treatise In Calumniatorem Platonis is a systematic approach to Platonic and Aristotelian philosophy written in response to George of Trebizond’s Comparatio Philosophorum Aristotelis et Platonis, which attacked Plato’s authority and proclaimed Aristotle’s superiority. A striking example of this is Bessarion’s attempt to defend Plato against George of Trebizond’s accusation that Plato did not offer sound arguments in favor of the immortality of the soul. In this article, I focus on Plato’s proof of the (...) immortality of the soul in the Phaedrus, as presented by Bessarion in the eighth chapter of the second book of the In Calumniatorem Platonis. The Phaedrusʼ proof is based on soul’s definition as a self-mover: since the soul always moves itself, it is the source of motion and is, therefore, ungenerated, imperishable and immortal. Bessarion’s interpretation of the Platonic proof gives the impression that Bessarion cites the text where Plato argues that the soul is immortal, and he summarises the text where Plato argues that the soul is ungenerated and imperishable. I argue, however, that Bessarion does not offer an original reading of the Phaedrus’ proof, and I also propose that Bessarion’s interpretation reflects his attempt to harmonize the Platonic and the Aristotelian views.

Georgius Trapezuntius Cretensis (1395-1472), an eminent humanist scholar who immigrated to Italy from Crete, is well appreciated for his treatises on philosophy and rhetoric, his commentary on Ptolemy’s Almagest (Syntaxis Mathematica) and his translations of Plato, Aristotle as well as of some Christian fathers. Trapezuntius’ works, although heavily criticized at times, contributed to Italian and Northern Renaissance. On the basis of major evidence, we will attempt in this paper to show the way Trapezuntius treated the Aristotelian and Platonic mathematics in (...) order to serve his personal goals in the rather peculiar intellectual climate of the mid 15th century.

One of the most learned men of his day and called -the philosopher- by contemporaries, George Amiroutzes (c. 1400-c. 1469) attended the Council of Florence (1438-39) as a lay scholar in the Greek delegation. As a high government official in his native Trebizond, he helped to negotiate the surrender of this last independent Greek state to Mehmed the Conqueror in 1461. He eventually entered the Sultan's household as someone with whom Mehmed enjoyed having intellectual discussions. Despite his contemporary (...) fame, however, almost no philosophical writings of his survive. The present work offers an edition of fifteen previously unknown philosophical tractates. Although they are unpublished drafts in a fragmentary state, the tractaes reveal Amiroutzes to be an Aristotelian philosopher influenced by Thomas Aquinas and firmly intent upon refuting Platonism. He also shows himself to be an original thinker in discussing ethics and metaphysics.". (shrink)

The beginning of the fifteenth century marks a new stage in the reception of the Platonic dialogues in the Latin West. Throughout the medieval period only four dialogues of Plato--the Timaeus, Phaedo, Meno, and part of the Parmenides--were accessible to Latin readers, and the study of Plato was almost wholly confined to the first of these texts, which is chiefly concerned with natural philosophy. In the first half of the fifteenth century this situation changed dramatically: six new dialogues or parts (...) of dialogues were translated by Leonardo Bruni, the Republic was translated three times, George of Trebizond made versions of the Laws, the Epinomis, and the Parmenides, and a dozen other dialogues were made available in Latin by various other translators. With the work of Marsilio Ficino, who published in 1484 the first translation of the Complete Works, the translation activity of the fifteenth century come to fruition. ;The renewed interest in translating Plato in the early fifteenth century was not however at first a renewal of Platonism. The translation of Plato made part of a cultural program whose premisses were in fact foreign to Platonic thought; Plato was instead put to the task of showing that pagan literature was compatible with Christianity, or read as a wise sage full of melodious maxims in usum scholarum, or so twisted as to endorse with his authority some political belief of the translators. These ulterior motives had their influence on the translations themselves, which were frequently excerpted, bowdlerized, or otherwise expurgated of inappropriate sentiments. Such philosophical understanding of Plato as the early humanists displayed was derived from the Philosophica of Cicero. ;It is only with the Plato-Aristotle controversy of mid-century that some more sophisticated understanding of Platonic philosophy begins to emerge. Despite the central role Plato played in his apocalyptic theology, George of Trebizond does not seem to have had a very firm grasp of Platonic thought, but his opponent in the controversy, Cardinal Bessarion, was able to draw upon the philosophical sagacity of the Byzantine and Western scholastic traditions, and produced a more penetrating, if at times incoherent, interpretation of Plato's thought. It is only with Marsilio Ficino however that philosophical understanding was combined with the philological attainments necessary to produce a respectable translation of Plato, and this may account for the great success Ficino's translations enjoyed in subsequent centuries.

Those who work with topics related to Modern Greek identity usually start discussing these issues by quoting the famous Georgios Gemistos Pletho (c.1360-1454): we, over whom you rule and hold sway, are Hellenes by genos (γένος), as is witnessed by our language and ancestral education. Although Woodhouse thought of Pletho as the last of the Hellenes, others prefer to denounce him the last of the Byzantines and the first and foremost Modern Greek. During the 14th and 15th centuries, a number (...) of influential intellectuals in the Eastern Roman Empire preferred the term Hellene (Ἓλλην) to identify themselves, instead of the formal Roman (Ρωμαῖος) and the common Greek (Γραικός). According to the prevalent view of modern scholarship, the shift should not be interpreted only as a statement of proto-national identity, but also as the outcome of growing archaism. As Vryonis pointed out, the historian Critoboulos used to call the Balkan nations with their archaic names: Byzantines became “Hellenes,” Albanians became “Illyrians,” etc. Chalkokondyles followed in the same path. Furthermore, in order to lament the decline of their Empire, byzantine intellectuals tended to compare their sad present to the glory of ancient Greece. Besides archaism, proto-nationalism and Hellenism, I suggest that a careful reading of the sources would lead us to reappraise the ways 15th century intellectuals perceived identity. Whilst I do not accept Vakalopoulos’ views on diachronic Hellenic identity, I support that, in the 15th century, Byzantine scholars attempted to create an identity based on cultural and historical continuity and otherness. Moreover, Laiou’s definition of Greek identity as a resultant of language, history, tradition and interests does not cover the case of 15th century Byzantine philosophers, since the latter strived to enrich and enlarge Greek identity with additional elements. It is worth noting that those philosophers who fled to Italy deliberately chose to describe themselves as Greeks (Greci/Γραικοί) or Hellenes (Ἓλληνες) and not as Romans (Ρωμιοί/Ρωμαῖοι), according to the Byzantine official terminology. During the 15th century a major shift occurred in the Byzantine intelligentsia and its prominent members revisited matters of identity. In this paper, I attempt to scrutinize the ways Byzantine philosophers of the 15th century, who lived in the territories of the Byzantine Empire and in Italy, perceived identity and otherness. In my research, I include not only Greek, but also Latin sources, since their works is written in both languages. (shrink)

George Berkeley's two major works, A Treatise Concerning the Principles of Human Knowledge and Three Dialogues Between Hylas and Philonous, are presented here, together with perhaps the most searching examination his ideas received during his lifetime, that of the American Samuel Johnson, who corresponded with Berkeley during his stay in the country.

Global Economy, Global Justice explores a vital question that is suppressed in most economics texts: "what makes for a good economic outcome?" Neoclassical theory embraces the normative perspective of "welfarism" to assess economic outcomes. This volume demonstrates the fatal flaws of this perspective--flaws that stem from objectionable assumptions about human nature, society and science. Exposing these failures, the book obliterates the ethical foundations of global neoliberalism. George DeMartino probes heterodox economic traditions and philosophy in search of an ethically viable (...) alternative to welfarism. Drawing on the work of Amartya Sen, DeMartino proposes the egalitarian principle of the "global harmonization of capabilities" to guide economics. This principle provides a basis for resisting oppression the world over while nevertheless demanding respect for cultural diversity. DeMartino puts this principle to work adjudicating contemporary debates over global policy regimes, and completes thebook with a set of deeply egalitarian global policies for the year 2025. Global Economy, Global Justice 's engaging prose will appeal to those seeking to understand the intersection between economics and political philosophy. Its focus on the normative foundations of contemporary policy disputes makes it unique in the literature on globalization. (shrink)

By delving into the history and development of logic from its beginnings to the modern era, George Englebretsen rehabilitates term logic and demonstrates that an enhanced traditional logic remains a viable possibility. Taking inspiration from Fred Sommers' work, he creates an updated and fascinating version of term logic; one he believes to be just as legitimate as, and in ways superior to, the currently predominant mathematical logic.

Plato’s Gorgias sets out to discuss the nature and aim of rhetoric. The dialogue was held in high esteem among late ancient Platonists and it resurfaced in Renaissance discussions about ethics. Olympiodorus produced an extensive commentary on the dialogue, emphasising its ethical content. In 1409, Leonardo Bruni provided the first complete Latin translation of the Gorgias with preface and annotations. Later in the Renaissance we find direct and indirect commentaries by George of Trebizond and Marsilio Ficino. I argue (...) that Ficino’s translation of, and commentary to, Plato’s Gorgias was a significant, but perhaps also unintended, contribution to the dissemination of ancient sophists in the Italian Renaissance. Ficino’s commentary to the Gorgias defends a legitimate and philosophical use of rhetoric, including the one we find in Plato’s own writings. Furthermore, Ficino treats the character Callicles – together with several other sophists in Plato’s dialogues – as an enemy of the Platonic-Pythagorean ethical ideal, maintaining that the sophists were wrong. Moreover, he treats ancient sophists as a fairly homogeneous group, unlike some of the ancient sources. (shrink)

This chapter addresses questions such as what is unique about human beings, and what makes humans human. It begins exploration of such questions by looking back on some of the major events and themes of the past 1000 years in Western civilization and the primitive human instincts they illustrate. The second millennium opened with holy wars: local wars, such as the Spanish Reconquista to retake Spain from the Moors, and the broader multi‐state Crusades to take the Holy Lands from the (...) Muslims. Many scholars date postmodernism from Hiroshima and the Holocaust, one an instantaneous annihilation, the other a systematic one. Like space exploration, work on human genetics is dominated by governmental agencies and commercial interests. The chapter argues that genocidal proclivity of the past millennium could lead to genocide on an even more horrible scale if we create a new or “better” human species (or subspecies) through genetic engineering.

ABSTRACT The list of proposed addictions has recently grown to include television, videogames, shopping, day trading, kleptomania, and use of the Internet. These activities share with a more established entry, gambling, the property that they require no delivery of a biological stimulus that might be thought to unlock a hardwired brain process. I propose a framework for analyzing that class of incentives that do not depend on the prediction of physically privileged environmental events: people have a great capacity to coin (...) endogenous reward; we learn to cultivate it, and, where it is entrapping, to minimize it, by managing internally generated appetites for it. The basic method of cultivating endogenous reward is to learn cues that predict when best to harvest the reward that has been made possible by the growth of these appetites. This hedonic management occurs in the same motivational marketplace as the instrumental planning that seeks environmental goods in the conventional manner, and presumably obeys the same laws of temporal difference learning; but these laws are no longer limiting. Furthermore, instrumental contingencies often provide the most productive structure for hedonic management as well, for reasons that I discuss; but the needs of hedonic management create incentives both to pursue instrumental goals in a suboptimal manner and to avoid noticing how the hedonic incentive affects this pursuit. The result is the apparent irrationality that is often observed in process addictions. (shrink)

Necessary and sufficient conditions are presented for the (first-order) theory of a universal class of algebraic structures (algebras) to have a model completion, extending a characterization provided by Wheeler. For varieties of algebras that have equationally definable principal congruences and the compact intersection property, these conditions yield a more elegant characterization obtained (in a slightly more restricted setting) by Ghilardi and Zawadowski. Moreover, it is shown that under certain further assumptions on congruence lattices, the existence of a model completion implies (...) that the variety has equationally definable principal congruences. This result is then used to provide necessary and sufficient conditions for the existence of a model completion for theories of Hamiltonian varieties of pointed residuated lattices, a broad family of varieties that includes lattice-ordered abelian groups and MV-algebras. Notably, if the theory of a Hamiltonian variety of pointed residuated lattices has a model completion, it must have equationally definable principal congruences. In particular, the theories of lattice-ordered abelian groups and MV-algebras do not have a model completion, as first proved by Glass and Pierce, and Lacava, respectively. Finally, it is shown that certain varieties of pointed residuated lattices generated by their linearly ordered members, including lattice-ordered abelian groups and MV-algebras, can be extended with a binary operation to obtain theories that do have a model completion.

Since the dawn of Romanticism, artists and intellectuals in Germany have maintained an abiding interest in the gods and myths of antiquity while calling for a new mythology suitable to the modern age. In this study, George S. Williamson examines the factors that gave rise to this distinct and profound longing for myth. In doing so, he demonstrates the entanglement of aesthetic and philosophical ambitions in Germany with some of the major religious conflicts of the nineteenth century. Through readings (...) of key intellectuals ranging from Herder and Schelling to Wagner and Nietzsche, Williamson highlights three crucial factors in the emergence of the German engagement with myth: the tradition of Philhellenist neohumanism, a critique of contemporary aesthetic and public life as dominated by private interests, and a rejection of the Bible by many Protestant scholars as the product of a foreign, "Oriental" culture. According to Williamson, the discourse on myth in Germany remained bound up with problems of Protestant theology and confessional conflict through the nineteenth century and beyond. A compelling adventure in intellectual history, this study uncovers the foundations of Germany's fascination with myth and its enduring cultural legacy. (shrink)

Quantum entanglement has long been thought to be have deep metaphysical consequences. For example, it has been claimed to show that Humean supervenience is false or to involve a novel form of ontological holism. One way to avoid confronting the metaphysical consequences is to adopt some form of antirealism. In this paper we discuss two prominent strands in recent literature—wavefunction realism and “Super-Humeanism”—that appear quite different, but, as we see it, are instances of a more general strategy. In effect, what (...) these attempt to do is to diffuse the puzzle of entanglement by eliminating it. These interpretative movements are advertised as equally realist, but, we claim, fail to take an appropriately realist attitude towards entanglement. What we advocate instead is a genuine metaphysics of entanglement: instead of eliminating entanglement, develop a metaphysics that accounts for and explains it. (shrink)
