Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most readers this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it remains. We think of it (...) as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where at the most fundamental level time disappears. He explains how the theory of quantum gravity attempts to understand and give meaning to the resulting extreme landscape of this timeless world. Weaving together ideas from philosophy, science and literature, he suggests that our perception of the flow of time depends on our perspective, better understood starting from the structure of our brain and emotions than from the physical universe.

This paper aims to offer a critique of a rigidly moralistic temperament in public discourse from the perspective of political realism. It unpacks three types of moralism in public discourse, and for each, it explains why it is normatively problematic from a realist perspective: ‘Moralist Causalism’ is the belief that moral preaching is an apt way to affect the world for the better; ‘Moralist Manicheism’ is a dichotomous division of the world between good and evil; ‘Moralist Absolutism’ is the conviction (...) that only morality matters when we answer the question, ‘What should we do?’. The paper then turns these negative criticisms into a positive recipe for how to look realistically at what is valuable in the world. First, there are not only multiple values in the world but also different sources of values (epistemic, instrumental, aesthetic…) which may conflict with one another. We call this requirement ‘Meta-Normative Pluralism’. Second, politics is pivotal because it is the sphere where the clashes among all other spheres of value are authoritatively resolved—a role which moralists usurp for morality. (shrink)

La presente investigación busca generar un diálogo entre la filosofía de las ciencias de Susan Haack y la teoría queer de Judith Butler. Para ello, recorreremos primero los hitos más importantes del feminismo y, en un segundo momento, veremos cómo estos desembocaron en la teoría queer. Luego, tomaremos como hilo conductor el problema del cuerpo y de la evidencia objetiva para analizar, en un tercer momento, la postura butleriana y, en un cuarto momento, la haackiana. Como sección conclusiva, pondremos ambas (...) posturas en diálogo considerando sus planteamientos en un caso concreto: la intersexualidad. (shrink)

A passage from Michael of Ephesus’ Commentary on the Nicomachean Ethics, book V (p. 50, 6–10 Hayduck), gives some information on the Anonymous Commentary on the Nicomachean Ethics, books II–IV. Michael cites a series of ancient annotations to the third book, written by ancient exegetes and which have come down to him. It can therefore be assumed that Michael had the Anonymous Commentary in front of him when he wrote these lines. It is thus possible to assume that it was (...) Michael of Ephesus himself who organised the entire commentary on the Nicomachean Ethics and inserted the Anonymous Commentary on Books II-IV after Eustratius’ commentary on Book I and before his own commentary on Book V.

ABSTRACT The mainstreaming of environmental concerns paradoxically obscures their political dimension: as the goals of environmentalism become accepted, they are reduced to administrative problems to be solved in a purely technocratic way. This technocratic environmentalism has fueled a populist backlash that challenges the scientific basis of environmentalism. As a result, contemporary environmentalism appears to be stuck in a depoliticizing opposition between technocracy and populism. A possible way out of this depoliticizing trap consists in recognizing the intrinsic contestability of the core (...) premises on which environmentalism is based, since it is not merely the result of a straightforward application of scientifically provable facts, but also depends on normative principles and value choices. This opens the possibility for an internal pluralization of environmentalism, which shifts emphasis from the depoliticizing struggle between technocratic environmentalism and populist anti-environmentalism to the inherently political rivalry between different types of environmentalism.

Quantum gravity poses the problem of merging quantum mechanics and general relativity, the two great conceptual revolutions in the physics of the twentieth century. The loop and spinfoam approach, presented in this book, is one of the leading research programs in the field. The first part of the book discusses the reformulation of the basis of classical and quantum Hamiltonian physics required by general relativity. The second part covers the basic technical research directions. Appendices include a detailed history of the (...) subject of quantum gravity, hard-to-find mathematical material, and a discussion of some philosophical issues raised by the subject. This fascinating text is ideal for graduate students entering the field, as well as researchers already working in quantum gravity. It will also appeal to philosophers and other scholars interested in the nature of space and time. (shrink)

This article argues for a new interpretation of the realist claim that politics is autonomous from morality and involves specific political values. First, this article defends an original normative source: functional normativity. Second, it advocates a substantive functional standard: political institutions ought to be assessed by their capacity to select and implement collective decisions. Drawing from the ‘etiological account’ in philosophy of biology, I will argue that functions yield normative standards, which are independent from morality. For example, a ‘good heart’ (...) is one that pumps blood well, and a good army is one that it is effective at exerting military force. I then interpret realism’s naturalistic conception of politics as an etiological function of social groups: namely making binding collective decisions under persistent disagreement. I conclude that political institutions should be evaluated realistically by how well they perform this task. Finally, I assess trade-offs between this functional political normativity and other moral values. I conclude that justice, fairness, freedom and equality remain obviously important concerns, but only once the basic political function is secured. (shrink)

This paper suggests that libertarians should avail themselves of a system of natural and autonomy-friendly motivational foundations—intrinsic motives. A psyche equipped with intrinsic motives could allow for some degree of character-formation that is genuinely and robustly autonomous. Such autonomy would rest on motives that are one’s own in the most direct way: they are part of one’s natural make-up. A model with intrinsic motives can help libertarians in multiple ways: to deal with skeptics regarding the very idea of robust self-making; (...) to explain the importance of autonomy (it helps explain how the agent can set her dominant life-goals on the basis of her own motives); to explain why an artificially induced, albeit rational, autonomy is less than genuine (it would not rely on the agent’s own motives).

Diano's Form and Event has long been known in Europe as a major work not only for classical studies but even more for contemporary philosophy, anticipating the work of Deleuze, Badiou, Esposito, and Agamben. It now appears in English for the first time, with a substantial Introduction that situates the book in the genealogy of modern political philosophy.

This volume examines the limitations of mathematical logic and proposes a new approach to logic intended to overcome them. To this end, the book compares mathematical logic with earlier views of logic, both in the ancient and in the modern age, including those of Plato, Aristotle, Bacon, Descartes, Leibniz, and Kant. From the comparison it is apparent that a basic limitation of mathematical logic is that it narrows down the scope of logic confining it to the study of deduction, without (...) providing tools for discovering anything new. As a result, mathematical logic has had little impact on scientific practice. Therefore, this volume proposes a view of logic according to which logic is intended, first of all, to provide rules of discovery, that is, non-deductive rules for finding hypotheses to solve problems. This is essential if logic is to play any relevant role in mathematics, science and even philosophy. To comply with this view of logic, this volume formulates several rules of discovery, such as induction, analogy, generalization, specialization, metaphor, metonymy, definition, and diagrams. A logic based on such rules is basically a logic of discovery, and involves a new view of the relation of logic to evolution, language, reason, method and knowledge, particularly mathematical knowledge. It also involves a new view of the relation of philosophy to knowledge. This book puts forward such new views, trying to open again many doors that the founding fathers of mathematical logic had closed historically. (shrink)

Quantum mechanics is not about 'quantum states': it is about values of physical variables. I give a short fresh presentation and update on the *relational* perspective on the theory, and a comment on its philosophical implications.

Is reality three-dimensional and becoming real (Presentism), or is reality four-dimensional and becoming illusory (Eternalism)? Both options raise difficulties. I argue that we do not need to be trapped by this dilemma. There is a third possibility: reality has a more complex temporal structure than either of these two naive options. Fundamental becoming is real, but local and unoriented. A notion of present is well defined, but only locally and in the context of approximations.

This paper challenges the ‘Standard Account’ of the so-called endoxic method that Aristotle articulates in a well-known passage from book VII of the Nicomachean Ethics. That account is problematic because it misreads what Aristotle says and thereby attributes to him an unusually rigid and conservative method that he himself does not seem to employ. This paper carefully analyzes the semantics and syntax of the book VII passage in order to present a novel and improved understanding of the endoxic method. This (...) improved account helps adjudicate scholarly debates about the method’s purpose and scope. (shrink)

The author describes his research experience in the 1960s as an apprentice historian in the Warburg Library. His work on witchcraft trials in early modern Italy, he argues, was deeply affected by the library’s unique character. Aby Warburg’s law of the “good neighbor” is illustrated through a specific example: the encounter with a forgotten tract dealing with some anomalous Bavarian witchcraft trials — a book that would have been very difficult to come across anywhere but Warburg’s Library.

The fragment 140 a S.-M. = G 8 Ruth. is likely to deal with two different feats of Herakles. The lines b 21–b 33 seem to concern Cycnus, an impious hero killed by Herakles by order of Apollo. The rest of the fragment seems to concern the beginning of Herakles’ expedition against Laomedon. I think Pindarus presupposes a legend according to which Herakles spent the most part of his life in Thebes; such an interpretation might explain both the obscure expression (...) πέραν ἰσϑμὸν διαβαίς and other details. The opinion the fragment belonged to the Paianes is in my view right. (shrink)

This is a contribution to a book on quantum gravity and philosophy. I discuss nature and origin of the problem of quantum gravity. I examine the knowledge that may guide us in addressing this problem, and the reliability of such knowledge. In particular, I discuss the subtle modification of the notions of space and time engendered by general relativity, and how these might merge into quantum theory. I also present some reflections on methodological questions, and on some general issues in (...) philosophy of science which are are raised by, or a relevant for, the research on quantum gravity.

At least since Kuhn’s Structure, philosophers have studied the influence of social factors in science’s pursuit of truth and knowledge. More recently, formal models and computer simulations have allowed philosophers of science and social epistemologists to dig deeper into the detailed dynamics of scientific research and experimentation, and to develop very seemingly realistic models of the social organization of science. These models purport to be predictive of the optimal allocations of factors, such as diversity of methods used in science, size (...) of groups, and communication channels among researchers. In this paper we argue that the current research faces an empirical challenge. The challenge is to connect simulation models with data. We present possible scenarios about how the challenge may unfold. (shrink)

In this paper I analyze four so-called “principles of expertise”; that is, good epistemic practices that are normatively motivated by the epistemological literature on expert judgment. I highlight some of the problems that the four principles of expertise run into, when we try to implement them in concrete contexts of application (e.g. in science committees). I suggest some possible alternatives and adjustments to the principles, arguing in general that the epistemology of expertise should be informed both by case studies and (...) by the literature on the use of experts in science practice.

Following a line of research that I have developed for several years, I argue that the best strategy for understanding quantum gravity is to build a picture of the physical world where the notion of time plays no role at all. I summarize here this point of view, explaining why I think that in a fundamental description of nature we must “forget time”, and how this can be done in the classical and in the quantum theory. The idea is to (...) develop a formalism that treats dependent and independent variables on the same footing. In short, I propose to interpret mechanics as a theory of relations between variables, rather than the theory of the evolution of variables in time. (shrink)

One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, Rovelli examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the 21-year-old Werner Heisenberg first developed quantum theory, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to (...) be magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious. As scientists and philosophers continue to fiercly debate the theory's meaning, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships, not substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for understanding the structure of reality and even the nature of consciousness. Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better understand our place in it. (shrink)
