The article offers an edition, translation and commentary of eight so-called book epigrams. They all stem from eleventh-century manuscripts containing the New Testament or commentaries on it, more specifically the Paris. Coisl. 199, the Vindobon. Theol. Gr. 302, the Paris. Coisl. 26, and the Vatic. Gr. 363. While most of them are unedited, the second one is a conflation of known epigrams, and the third an unknown version of a previously edited epigram. Although book epigrams are frequently encountered in Byzantine (...) manuscripts, the genre has not received much attention. In the track of the recently increasing interest in manuscripts as cultural artifacts in their own right, our commentary focuses on the relationship between epigram and manuscript, and the process of copying. It also discusses textual problems, structure, content, function, vocabulary, and metrical features of the poems. The analysis is enriched by parallels from other, mostly contemporary, book epigrams, which were collected during an ongoing database project at Ghent University. The comparison shows, among other things, that the material belonging to this genre is ‘recyclable’: it is constantly re-used, sometimes with slight but meaningful modifications. (shrink)

L'économie solidaire est dépendante de la sphère publique au sens d'espace de communication. Il est en effet nécessaire d'avoir des échanges démocratiques dans ce type de relation sociale, car la solidarité implique que soient pris en compte tous les points de vue, et en particulier celui des populations démunies avec leur participation. L'économie libérale est le contraire : seul le point de vue de la rentabilité à travers la « main invisible du marché » est pris en compte et pas (...) les autres. En conséquences, l'économie solidaire implique que l'espace public s'étende du politique à l'économique.The civil solidarity-based economy depends on the public sphere for its role as a sphere of communication. Democratic exchanges are necessary in this type of social relation because solidarity implies that all viewpoints should be heard particularly those of disadvantaged population groups. The liberal economy is the opposite of this as only the “profitability” viewpoint and the “invisible hand of market forces” are taken into account and all others ignored. Consequently, the civil and solidarity-based economy means that the public sphere is extended from the political to the economic sphere. (shrink)

This article addresses the question under what conditions it is still possible to think in today’s era of the Anthropocene, in which the human has become the key factor in the evolution of the biosphere, considering the fact, structurally neglected by philosophy, that thinking is thoroughly conditioned by a technical milieu of retentional dispositives. The Anthropocene results from modern technology’s domination of the earth through industrialization that is currently unfolding as a process of generalized, digital automation, which tends to eliminate (...) reflection and to block any genuine questioning of its own development, producing a state of generalized entropy at all levels—ecological, psychic, social, economic, and, in particular, the noetic or thinking. The radical undermining of the very possibility of thinking and questioning, thought by Martin Heidegger in terms of Enframing, should be understood as a pharmacological situation that calls for a therapeutic reversal of the toxicity of current digital technologies into a remedial instrument for realizing a negentropic turn beyond the Anthropocene and toward the Neganthropocene. This requires that thinking starts to understand itself as caring, i.e., as a taking care of itself by taking care of the technical pharmaka that thoroughly constitute and condition it and that can render human life as noetic life both deeply unlivable and profoundly worthwhile.

Philosophy should not try to assimilate itself to the aims of the sciences. Scientism stems from the false assumption that a representation of the world minimally based on local perspectives is what best serves self-understanding. Philosophy must concern itself with the history of our conceptions, and we must overcome the need to think that this history should ideally be vindicatory. There is no basic conflict between arguing within the framework of our ideas, reflectively making better sense of them, and understanding (...) their highly contingent history. The third of these activities is an inescapable part of the second. (shrink)

A computable structure $\mathcal {A}$ is $\mathbf {x}$-computably categorical for some Turing degree $\mathbf {x}$ if for every computable structure $\mathcal {B}\cong\mathcal {A}$ there is an isomorphism $f:\mathcal {B}\to\mathcal {A}$ with $f\leq_{T}\mathbf {x}$. A degree $\mathbf {x}$ is a degree of categoricity if there is a computable structure $\mathcal {A}$ such that $\mathcal {A}$ is $\mathbf {x}$-computably categorical, and for all $\mathbf {y}$, if $\mathcal {A}$ is $\mathbf {y}$-computably categorical, then $\mathbf {x}\leq_{T}\mathbf {y}$. We construct a $\Sigma^{0}_{2}$ set whose degree (...) is not a degree of categoricity. We also demonstrate a large class of degrees that are not degrees of categoricity by showing that every degree of a set which is 2-generic relative to some perfect tree is not a degree of categoricity. Finally, we prove that every noncomputable hyperimmune-free degree is not a degree of categoricity. (shrink)

This essay asks why Aristotle, certainly no friend to unlimited democracy, seems so much more comfortable with unconstrained rhetoric in political deliberation than current defenders of deliberative democracy. It answers this question by reconstructing and defending a distinctly Aristotelian understanding of political deliberation, one that can be pieced together out of a series of separate arguments made in the Rhetoric, the Politics, and the Nicomachean Ethics.

Abstract The idea of a purely civic nationalism has attracted Western scholars, most of whom rightly disdain the myths that sustain ethnonationalist theories of political community. Civic nationalism is particularly attractive to many Americans, whose peculiar national heritage encourages the delusion that their mutual association is based solely on consciously chosen principles. But this idea misrepresents political reality as surely as the ethnonationalist myths it is designed to combat. And propagating a new political myth is an especially inappropriate way of (...) defending the legacy of Enlightenment liberalism from the dangers posed by the growth of nationalist political passions.

No understanding of morality has more zealous or influential defenders among academic philosophers than Kant’s. Yet as Michael Rosen demonstrates in The Shadow of God, there is a sense in which Kant’s critics take his conception of freedom more seriously nowadays than his defenders. As a result, contemporary versions of “Kantian ethics” often end up challenging what Rosen calls “the ethics of Kant,” not just the claims of rival moral theories. Rosen supports this surprising conclusion with some powerful arguments, showing (...) that we cannot make sense of Kantian moral philosophy or its extraordinary impact on modern philosophy while detaching it from Kant’s conception of transcendental freedom. But Rosen overstates the continuity between Kant and the Idealist philosophers that he inspired. Thinkers like Schiller, Schelling, and Hegel took Kant’s concept of transcendental freedom far more seriously than defenders of Kantian ethics do today. But precisely because they did so, they felt compelled to address a whole new set of problems, which could be solved only by radically transforming the conception of freedom that they received from Kant.

An old question, still much discussed in moral philosophy, is whether there is any ethical knowledge. It is closely related, by simple etymology, to the question of cognitivism in ethics. Despite the fact that the terms ‘cognitivism’ and ‘objectivism’ seem sometimes to be used interchangeably, I take it that the question whether there can be ethical knowledge is not the same as the question whether ethical outlooks can be objective. A sufficient reason for this is that an ethical outlook might (...) be taken to consist of rules or principles, which do not admit of truth or falsehood and so cannot be objects of knowledge, but which can be seen as having an objective basis.

The cybernetic definition of a living individual proposed previously (Korzeniewski, 2001) is very abstract and therefore describes the essence of life in a very formal and general way. In the present article this definition is reformulated in order to determine clearly the relation between life in general and a living individual in particular, and it is further explained and defended. Next, the cybernetic definition of a living individual is confronted with the real world. It is demonstrated that numerous restrictions imposed (...) on the cybernetic definition of life by physical reality imply a number of particular properties of life that characterize present life on Earth, namely: (1) a living individual must be a dissipative structure (and therefore a low-entropy thermodynamic system out of the state of equilibrium); (2) spontaneously-originated life must be based on organic compounds; (3) evolutionarily stable self-dependent, free-living individuals must have some minimal level of complexity of structure and function; (4) a living individual must have a record of identity separated from an executive machinery; (5) the identity of living individuals must mutate and may evolve; (6) living individuals may collect and accumulate information in subsequent generations over very long periods of time; (7) the degree of complexity of a living individual reflects the degree of complexity of its environment (ecological niche) and (8) living individuals are capable of supple adaptation to varying environmental conditions. Thus, the cybernetic definition of a living individual, when confronted with the real physical world, generates most of the general properties of the present life on Earth. (shrink)

ABSTRACT This paper reconsiders the arguments of my book, The Longing for Total Revolution, in response to the thoughtful analyses collected in this symposium. It restates the book’s main genealogical and critical arguments about the philosophical sources of uniquely modern forms of social discontent, while distinguishing those arguments from recent attempts to uncover the deeper, theological sources of discontent. It focuses, in particular, on the role played in modern social discontent by the group of thinkers I describe as the “Kantian (...) left”: a long line of social critics who sought to “realize” Kant’s understanding of human autonomy in society, thereby gaining what Marx called “control and conscious mastery” over our social world, not just over our wills.

Modified numerals, such as at least three and more than five, are known to sometimes give rise to ignorance inferences. However, there is disagreement in the literature regarding the nature of these inferences, their context dependence, and differences between at least and more than. We present a series of experiments which sheds new light on these issues. Our results show that the ignorance inferences of at least are more robust than those of more than, the presence and strength of the (...) ignorance inferences triggered by both at least and more than depends on the question under discussion, and whether ignorance inferences are detected in a given experimental setting depends partly on the task that participants are asked to perform. We offer an Optimality Theoretic account of these findings. In particular, the task effect is captured by assuming that in performing an acceptability task, participants take the speaker’s perspective in order to determine whether an expression is optimal given a certain epistemic state, while in performing an inference task they take the addressee’s perspective in order to determine what the most likely epistemic state of the speaker is given a certain expression. To execute the latter task in a fully rational manner, participants have to perform higher-order reasoning about alternative expressions the speaker could have used. Under the assumption that participants do not always perform such higher-order reasoning but also often resort to so-called unidirectional optimization, the task effect finds a natural explanation. This also allows us to relate our finding to asymmetries between comprehension and production that have been found in language acquisition. (shrink)

The problem of time involves an overlap between physics, philosophy, psychology and neuroscience. My talk will discuss the role of time in physics but also emphasize that physics may need to expand to address issues usually regarded as being in the other domains. I will first review the mainstream physics view of time, as it arises in Newtonian theory, relativity theory and quantum theory. I will then discuss the various arrows of time, the most fundamental of which is the passage (...) of time associated with consciousness. I will argue that this goes beyond both relativity theory and quantum theory, so that one needs some new physical paradigm to accommodate it. A new paradigm is required anyway to describe quantum gravity and this may elucidate the nature of both time and consciousness. (shrink)

The Prague Philosopher Bernard Bolzano (1781-1848) has long been admired for his groundbreaking work in mathematics: his rigorous proofs of fundamental theorems in analysis, his construction of a continuous, nowhere-differentiable function, his investigations of the infinite, and his anticipations of Cantor's set theory. He made equally outstanding contributions in philosophy, most notably in logic and methodology. One of the greatest mathematician-philosophers since Leibniz, Bolzano is now widely recognised as a major figure of nineteenth-century philosophy. Praised by Husserl as “one (...) of the greatest logicians of all times,” he has also been recognised by Michael Dummett as one of the first modern analytic philosophers and by Alberto Coffa as the founder of the “semantic tradition.” This volume contains English translations of the essay “On the Mathematical Method,” a concise introduction to Bolzano’s logic and philosophy of mathematics, as well as substantial selections from his correspondence with Franz Exner, Professor of Philosophy at the Charles University in Prague in the 1830s and 40s. It will be of interest to students of Austrian philosophy, the development of analytic philosophy, the philosophy of language, and the history and philosophy of logic and mathematics. (shrink)

This paper uses E. M. Forster’s novel Howards End to help articulate what I describe as a moral pluralist approach to moral conflict. Moral pluralism, I argue here, represents a way of responding to the moral conflicts we encounter in our lives, rather than the mere acknowledgment of their inevitability, as suggested by value pluralists like Isaiah Berlin. The tragic view of moral conflict epitomized by Sophocles’ Antigone and endorsed by most theories of value pluralism, tells us that we must (...) choose between moral commitments and reconcile ourselves to the moral regrets that inevitably follow from moral choice. The moral pluralist view, in contrast, suggests that we should seek means, however imperfect, of satisfying conflicting moral commitments and minimizing causes for moral regret. That view, I argue, drives the words and actions of Forster’s heroine in Howards End, Margaret Schlegel. Confronted with a battle between a willful patriarch and a self-righteous sister, a conflict that maps neatly onto the central conflict in Sophocles’ tragedy, Margaret refuses to take sides without refusing to make moral choices. And in doing so, she comes to exemplify an unexpected kind of moral heroism. (shrink)

The justification of Bayes' rule by cognitive rationality principles is undertaken by extending the propositional axiom systems usually proposed in two contexts of belief change: revising and updating. Probabilistic belief change axioms are introduced, either by direct transcription of the set-theoretic ones, or in a stronger way but nevertheless in the spirit of the underlying propositional principles. Weak revising axioms are shown to be satisfied by a General Conditioning rule, extending Bayes' rule but also compatible with others, and weak updating (...) axioms by a General Imaging rule, extending Lewis' rule. Strong axioms (equivalent to the Miller–Popper axiom system) are necessary to justify Bayes' rule in a revising context, and justify in fact an extended Bayes' rule which applies, even if the message has zero probability.

The paper argues that in our usage of moral language we relate three concepts: guilt, forgiveness, and reconciliation. This assumes that we can distinguish between external actions and internal executions, because guilt as well as forgiveness and reconciliation are realities that first affect our inner humanity. When a relationship has been damaged by culpable actions (sometimes even by both sides), forgiveness is the precondition of reconciliation. As long as people accuse each other, there can be no talk of true reconciliation. (...) Although these are attitudes, that is, inner engagements, reconciliation also becomes outwardly recognizable as peace. However, these relationships can only be explained well in the connections of individual persons to each other. When political communities confront each other, our moral sense becomes fuzzy, because it is not so easy to say how such collectives (e.g., peoples) are to be determined in their inside and outside. Who can and may forgive, if other persons have become victims of culpable actions, but cannot forgive themselves? Here, then, the difficulty of individuality and collectivity is added. The essay pleads for maintaining the conceptual conjunction between individual and collective forgiveness. However, this should not be done at the price of a complete socio-ontological dissolution of collectives. Therefore, one must also be cautious about rash universalistic appropriation of the Other or the other group, because this is usually accompanied by a failure to recognize and endure the selfhood of the Other. Before it comes to a “false” reconciliation in this way, it is better to at least recognize each other – also in diversity. This should also be reflected in the rules of conflict, which must above all be oriented toward ensuring that conflicts are not carried out in such a way that the manner in which the conflict is carried out makes reconciliation impossible. But in both collective and individual reconciliation, the person does not have the outcome of the process entirely in his or her own hands. Reconciliation is not a technique, but a relational event that is carried out in an “open space.”. (shrink)

The scholastic philosopher is interested in definition for a different reason than the lexicographer and linguist. The philosopher is trying to learn things. Fe defines, after investigating reality, in an attempt to describe reality clearly and to sum up some aspect of his understanding of reality. Hence, we find our scholastic philosophers adopting as a main feature of their method this insistence on defining, on precise and detailed explanation of their definitions, and on proving that their definitions da correctly express (...) what a nature or activity is.

We define the bounded jump of $A$ by $A^{b}=\{x\in \omega \mid \exists i\leq x[\varphi_{i}\downarrow \wedge\Phi_{x}^{A\upharpoonright \!\!\!\upharpoonright \varphi_{i}}\downarrow ]\}$ and let $A^{nb}$ denote the $n$th bounded jump. We demonstrate several properties of the bounded jump, including the fact that it is strictly increasing and order-preserving on the bounded Turing degrees. We show that the bounded jump is related to the Ershov hierarchy. Indeed, for $n\geq2$ we have $X\leq_{bT}\emptyset ^{nb}\iff X$ is $\omega^{n}$-c.e. $\iff X\leq_{1}\emptyset ^{nb}$, extending the classical result that $X\leq_{bT}\emptyset '\iff (...) X$ is $\omega$-c.e. Finally, we prove that the analogue of Shoenfield inversion holds for the bounded jump on the bounded Turing degrees. That is, for every $X$ such that $\emptyset ^{b}\leq_{bT}X\leq_{bT}\emptyset ^{2b}$, there is a $Y\leq_{bT}\emptyset ^{b}$ such that $Y^{b}\equiv_{bT}X$. (shrink)

Abduction was first introduced in the epistemological context of scientific discovery. It was more recently analyzed in artificial intelligence, especially with respect to diagnosis analysis or ordinary reasoning. These two fields share a common view of abduction as a general process of hypotheses formation. More precisely, abduction is conceived as a kind of reverse explanation where a hypothesis H can be abduced from events E if H is a good explanation of E. The paper surveys four known schemes for abduction (...) that can be used in both fields. Its first contribution is a taxonomy of these schemes according to a common semantic framework based on belief revision. Its second contribution is to produce, for each non-trivial scheme, a representation theorem linking its semantic framework to a set of postulates. Its third contribution is to present semantic and axiomatic arguments in favor of one of these schemes, ordered abduction, which has never been vindicated in the literature. (shrink)

Anderson and Csima :245–264, 2014) defined a jump operator, the bounded jump, with respect to bounded Turing reducibility. They showed that the bounded jump is closely related to the Ershov hierarchy and that it satisfies an analogue of Shoenfield jump inversion. We show that there are high bounded low sets and low bounded high sets. Thus, the information coded in the bounded jump is quite different from that of the standard jump. We also consider whether the analogue of the Jump (...)

Two main schemes explain how a system adapts to its environment. Evolutionary models are grounded on three usual processes (variation, transmission, selection) acting at the population level. Learning models are concerned with the endogenous search for a better performance at the individual level. The first ones were initially favored by biology and the second well illustrated by game theory. The article examines first how game theory went to evolution and how biology later considered learning. It shows some examples of a (...) hybrid use of models of each type. It finally proposes a common framework for both types of models. (shrink)
