Today, the field of Parmenidean studies is still divided over the fundamental question of the correct exegesis of the verb 'to be' in the poem On Nature. The two principal interpretative lines supported by scholars are, on the one hand, the traditional view that understands the verb ‘to be’ in its existential sense and, on the other, the one that arose in the 20th century that focuses on its predicative sense. This paper examines the latest and most ambitious attempt to (...) interpret the thought of Parmenides and the profound influence that he had on pluralist philosophers, starting from a purely predicative approach. It is an epistemological interpretation of the Eleaticism proposed by Patricia Curd, centred on the notion of ‘predicational monism’, which has the unquestionable merit to place Parmenides within the pre-Socratic naturalistic debate but that, after a careful analysis, fails to convince. In fact, this interpretation, which certainly appears to be one of the most articulate and intelligent proposals of recent years, raises a series of exegetical and argumentative problems that do not seem possible to resolve without exiting the predicative horizon.

The traditional interpretation of Eleatism has it that Melissus was a disciple of Parmenides and that Parmenides believed in the timeless eternity of Being. It seems, on the contrary, that Melissus acknowledged the reality of time by conceiving eternity as infinite time. Failing to justify this particular divergence from Parmenides’ approach, certain authors held that it was necessary to reinterpret the Melissan eternity as a form of infinite timelessness. This paper attempts to demonstrate that this reading is groundless and that (...) if the traditional interpretation is questioned then one should reconsider the assumptions and but not. (shrink)

For a long time, Parmenides has been considered the first real metaphysician in history, a theorist of a disembodied being, unreachable by the scientific knowledge of the world. In his Eleatic Lectures, Giovanni Cerri goes back to his renown interpretation of Parmenides as a scientist fully aware of the epistemological foundations of knowledge, and capable of foreshadowing the ultimate outcome of the evolution of science, that is, the discovery of being as a single homogeneous body. Cerri also shows that the (...) works of two other thinkers who were trained in the heart of the school of Elea itself support his interpretation: on the one hand Zeno, with his arguments against plurality; on the other hand Leucippus, the inventor of atomism. Ten scholars have been called to discuss this broad interpretation of a crucial page in the history of thought. Cerri replies to each of them in the final pages of the volume, engaging in a dense dialogue. (shrink)

We present an account of semantics that is not construed as a mapping of language to the world but rather as a mapping between individual meaning spaces. The meanings of linguistic entities are established via a “meeting of minds.” The concepts in the minds of communicating individuals are modeled as convex regions in conceptual spaces. We outline a mathematical framework, based on fixpoints in continuous mappings between conceptual spaces, that can be used to model such a semantics. If concepts are (...) convex, it will in general be possible for interactors to agree on joint meaning even if they start out from different representational spaces. Language is discrete, while mental representations tend to be continuous—posing a seeming paradox. We show that the convexity assumption allows us to address this problem. Using examples, we further show that our approach helps explain the semantic processes involved in the composition of expressions. (shrink)

Replying to Queen Elizabeth II who in November 2008 asked why so few economists had warned about the emerging financial crisis, a group of eminent economists of the British Academy, claimed that while this failure had many causes, the most important was principally a failure of the collective imagination of many bright people, to understand the risks to the system as a whole. The paper suggests that this failure is due also to the still heavy influence of the paradigm of (...) rational expectations, that did not provide the intellectual tools to grasp the signs of the impending financial crisis. The paper explores the development of Muth’s rational expectations hypothesis and the parallel development of Simon’s idea of bounded rationality—two opposite views about economic behavior that originated in the same context, during the early 1960s at Carnegie Mellon. It is shown that the latter, while marginalized for decades from the core economic ideas, generated a wide development in cognitive psychology, problem solving and experimental economics that grew up in the last decades and now permit a more profound analysis of human behavior in economic and organizational contexts, that can be the seed of a new thinking in economics. The challenge for economists is to use this new toolbox to incorporate in their models real human behaviors, getting out from the economy of wishful thinking. (shrink)

Sewall Wright introduced the metaphor of evolution on “adaptive landscapes” in a pair of papers published in 1931 and 1932. The metaphor has been one of the most influential in modern evolutionary biology, although recent theoretical advancements show that it is deeply flawed and may have actually created research questions that are not, in fact, fecund. In this paper I examine in detail what Wright actually said in the 1932 paper, as well as what he thought of the matter at (...) the very end of his career, in 1988. While the metaphor is flawed, some of the problems which Wright was attempting to address are still with us today, and are in the process of being reformulated as part of a forthcoming Extended Evolutionary Synthesis.

The purpose of the present article is to show that the key to understanding the philosophical meaning of the Two Modes of Scepticism is directly linked to the metaepistemic function performed by the criterion of truth (kriterion tes aletheias) in the Hellenistic theories of knowledge. Since the criterion can also be regarded as an epistemic instrument through which it is possible to immediately identify the foundational elements upon which our knowledge of the world is based, the Two Modes show the (...) problems that arise when we try to incontrovertibly identify a set of special and foundational elements that have no need of further justification.

Decision-making assisted by algorithms developed by machine learning is increasingly determining our lives. Unfortunately, full opacity about the process is the norm. Would transparency contribute to restoring accountability for such systems as is often maintained? Several objections to full transparency are examined: the loss of privacy when datasets become public, the perverse effects of disclosure of the very algorithms themselves, the potential loss of companies’ competitive edge, and the limited gains in answerability to be expected since sophisticated algorithms usually are (...) inherently opaque. It is concluded that, at least presently, full transparency for oversight bodies alone is the only feasible option; extending it to the public at large is normally not advisable. Moreover, it is argued that algorithmic decisions preferably should become more understandable; to that effect, the models of machine learning to be employed should either be interpreted ex post or be interpretable by design ex ante.

The aim of this essay is to focus the function of women in Aristophanes’ theatre and in Plato’s book V of the Republic, in an attempt to compare the different strategies adopted by these two authors in staging the female subject on the scene of their respective writings. This enquiry involves raising some fundamental questions such as : is the world of women, evoked by Aristophanes in his dramas and by Plato in his dialogues, a simple metaphor and a mere (...) instrument, if not an utopian mirage, of political theorizing? If this is not the case, what is the real and practical importance of women within the models of society and collective life outlined by Aristophanes and Plato? Do Aristophanes and Plato share a same perspective about the role of women in their hypothetical ideal cities? If not, what are the differences between Aristophanes’ and Plato’s views on this matter?

In this paper a new trajectory-based representation to non-relativistic quantum mechanics is formulated. This is ahieved by generalizing the notion of Lagrangian path which lies at the heart of the deBroglie-Bohm “ pilot-wave” interpretation. In particular, it is shown that each LP can be replaced with a statistical ensemble formed by an infinite family of stochastic curves, referred to as generalized Lagrangian paths. This permits the introduction of a new parametric representation of the Schrödinger equation, denoted as GLP-parametrization, and of (...) the associated quantum hydrodynamic equations. The remarkable aspect of the GLP approach presented here is that it realizes at the same time also a new solution method for the N-body Schrödinger equation. As an application, Gaussian-like particular solutions for the quantum probability density function are considered, which are proved to be dynamically consistent. For them, the Schrödinger equation is reduced to a single Hamilton–Jacobi evolution equation. Particular solutions of this type are explicitly constructed, which include the case of free particles occurring in 1- or N-body quantum systems as well as the dynamics in the presence of suitable potential forces. In all these cases the initial Gaussian PDFs are shown to be free of the spreading behavior usually ascribed to quantum wave-packets, in that they exhibit the characteristic feature of remaining at all times spatially-localized.

The Bible is the Word of God as expressed in human language. The goal of the present article is to develop a hermeneutical approach based in the communicative function of language. It first takes up the constitutive elements of the communicative event and the different patterns of representation. It then focuses in the exact operative function of language so as to clarify the relation between the semantic content and its pragmatic usage. Finally, it analyzes the specific characteristic of a biblical (...) text to apply the above communicative process to the analytical interpretation of a literary text. (shrink)

This contribution offers a reflection on the death penalty in the light of OT Law that enforced and sanctioned it only within the scope of the biblical understanding of justice. Starting therefore with the Torah and moving through the Prophets into the New Testament, the reader is called to question the logic behind retributive justice, as it attempts to re-establish the desecrated order. Retributive justice does so by means of a 'just' punishment, by giving everyone one's due, and through the (...) emendation of the culprit. The cross, though, goes well beyond the understanding of God as symmetry and the concept of a 'matching' justice. In Christ's death, the first place cannot be accorded to an order that needs to be set right again; still less can it be given to the suppression of bad subjects. That first place must belong to the human person who cries out for redemption and asks to be re-created in God's image. This would amount to nothing less than a restitutio principii. (shrink)

The paper examines three essays that Leibniz wrote in 1688, immediately after the composition of the Discourse on Metaphysics, one of his most organic philosophical works. The main topics which emerge from these essays are: the relationship between substance and accidents; the nature of accidents; and, more generally, the nature of abstract entities. Given that accidents' nature is that of changing, Leibniz sees how hard it is to give an account of the relationship between substance and accidents that does not (...) imply any change in the substance, when its accidents undergo a change. To find a way out of this problem, Leibniz assumes that abstract terms (whiteness, wisdom, etc.) do not name real properties or real parts of substances, and that any sentence containing real abstract terms can be rephrased as a sentence containing logical abstract terms, which do no imply any commitment to the existence of real properties. Coherently with this nominalistic attitude, Leibniz ends up, in the Theodicy and in his correspondence with Des Bosses, considering accidents as modes or internal modifications of the substance.

This paper takes the dichotomy between “exclusive” and “inclusive” positivism and applies it by analogy to natural-law theories. With John Finnis, and with Beyleved and Brownsword, we have examples of “exclusive natural-law theory,” on which approach the law is valid only if its content satisfies a normative monological moral theory. The discourse theories of Alexy and Habermas are seen instead as “inclusive natural-law theories,” in which the positive law is a constitutive moment in that it identifies moral rules and specifies (...) their meaning. The article argues that inclusive theories of natural law are better suited to expressing an authentic “republican” attitude.*In the seed of the city of the just, a malignant seed is hidden, in its turn: the certainty and pride of being in the right.

In this paper I outline a theory of legitimacy that grounds the state’s right to rule on a natural duty not to harm others. I argue that by refusing to enter the state, anarchists expose those living next to them to the dangers of the state of nature, thereby posing an unjust threat. Since we have a duty not to pose unjust threats to others, anarchists have a duty to leave the state of nature and enter the state. This duty (...) correlates to a claim-right possessed by those living next to them, who also have a right to act in self-defence to enforce this obligation. This argument, if successful, would be particularly attractive, as it provides an account of state legitimacy without importing any normative premises that libertarians would reject. (shrink)
