Provides a critical and analytical history of ancient Greek theories on the nature of pleasure, and of its value and rolein human lfie, from the ealriest times down to the period of Epicurus and the early Stoics.

Pleasure and Desire The Case of Hedonism Reviewed.

Weakness of the Will gives an excellent historical survey of philosophers' puzzles about the possibility of deliberately taking the worse course. Plato, Aristotle, the Stoics, a selection of medieval philosophers, and more contemporary philosophers are explored to illustrate why and how they avoid discussing the problem.

I want to start this paper by drawing a distinction between two uses of the word ‘conscience’ in order to get clear just what it is I shall talk about. The distinction I want to make can perhaps best be brought out by reference to a type of situation which could equally well be described in one or other of two ways, each way illustrating one use of the word ‘conscience’. Suppose then that we have a man who has been (...) brought up to think that it is a good thing to help the poor. This lesson he has been taught, at least in part, by being told stories about beggars asking for money. The good person gives money to the beggars and the wicked person callously refuses it. One year he decides to book himself a holiday in Spain. Before he goes, however, he has a conversation with a social scientist friend. This friend points out to him that the one thing he should not do when in Spain is give money to beggars. Beggary, he argues, is a social evil and one which will only be removed if people take a stand and refuse to go on giving money when asked. The appropriate action to take is to inform the beggar of the whereabouts of the local employment exchange, or take him along to an employer, or do one or other of various rather embarrassing things. If the worst comes to the worst, it is better simply to walk away than to give money. Our man goes to Spain convinced by this argument and realising the unsophisticated and over-simple nature of his earlier moral approach. Before long, a beggar comes up to him and asks for money. Let's suppose that he refuses to give it, because of his newly acquired conviction. Now it seems to me that when he returns he could describe this situation in one or other of two ways without there being any difference as regards the facts that he is asserting. (shrink)

In this paper, we propose a new and simple method for image encryption. It uses an external secret key of 128 bits long and an internal secret key. The novelties of the proposed encryption process are the methods used to extract an internal key to apply the zigzag process, affine transformation, and substitution-diffusion process. Initially, an original gray-scale image is converted into binary images. An internal secret key is extracted from binary images. The two keys are combined to compute the (...) substitution-diffusion keys. The zigzag process is firstly applied on each binary image. Using an external key, every zigzag binary image is reflected or rotated and a new gray-scale image is reconstructed. The new image is divided into many nonoverlapping subblocks, and each subblock uses its own key to take out a substitution-diffusion process. We tested our algorithms on many biomedical and nonmedical images. It is seen from evaluation metrics that the proposed image encryption scheme provides good statistical and diffusion properties and can resist many kinds of attacks. It is an efficient and secure scheme for real-time encryption and transmission of biomedical images in telemedicine. (shrink)

The question of whether the ascended and glorified body of Christ retains the marks of the wounds first became an issue of theological importance in the fifth century with the writings of Cyril of Alexandria and it continued to be developed until the Reformation, when both Luther and Calvin rejected the idea. For the patristic and medieval theologians, the enduring reality of the wounds testify to the intimate connnection between the economy of God’s salvific work within the created order (...) and the eternal economy. It underscored God’s ongoing good intention for, and engagement with, fallen creation. However transformed in glory, the ascended Christ is not to be thought of as dehominised and the evidence of his history as the incarnate and suffering human being is not to be erased. Suffering and sinful humanity finds itself in the Son at the right hand of the Father and it can see there the evidence that the divine heart has and continues to beat with compassion for humanity in its continuing brokenness. It is the enduring presence of the marks of the wounds in heaven that testifies to the divine engagement with the sinful human condition, in both judgment and mercy, which in turn is the basis of humankind’s response of thankfulness. Résumé L’idée que le corps glorifié du Christ, lors de son Ascension, portait ou ne portait pas les stigmates de ses souffrances, devint une question théologique importante pour la première fois au ve siècle, dans les écrits de Cyrille d’Alexandrie, et continua d’être discutée jusqu’à la période de la Réforme, lorsque Luther et Calvin rejetèrent d’emblée cette idée. Aux yeux des Pères de l’Église et des théologiens de l’époque médiévale, la permanence des plaies ouvertes témoignait du rapport étroit entre l’économie salvifique de Dieu à l’intérieur d’un ordre créé et l’économie éternelle. Cela soulignait la continuité de la bienveillance de Dieu et son engagement envers la création déchue. Même glorifié, le Christ de l’Ascension ne doit pas être perçu comme non humain, et les preuves de son passage sur la terre, comme être humain ayant connu la souffrance, ne doivent pas être effacées. Une humanité pécheresse et souffrante se retrouve dans le Fils, à la droite du Père, et reconnaît la compassion du Coeur divin qui continue de battre pour l’humanité sans cesse brisée. La présence durable au ciel des plaies ouvertes témoigne de l’engagement de Dieu envers l’humanité pécheresse, dans son jugement ou sa clémence ; en retour, cet engagement s’avère être le fondement de la réponse de gratitude de l’humanité.

_ Source: _Volume 35, Issue 1, pp 32 - 52 In the 1630s, Grotius was engaged in extensive reading of patristic texts. From his involvement with these texts come the numerous and sometimes extensive quotations from patristic texts in the Annotata of De veritate religionis Christianae, which accompanied the work starting in 1640. Grotius was particularly interested in the apologetic literature of the ancient Church, which can also be seen in his correspondence. Strikingly, Grotius cites individual passages from texts that (...) had not yet appeared in print, which he could only have learned of from the circle of those who, in 1630s Paris, were working to produce editions of various Greek texts. The texts in question are Cyril of Alexandria, Contra Julianum, and the letter of Barnabas. Grotius had received a handwritten copy of the Barnabas letter, which he later bound into his notebook amid excerpts of patristic texts. This shows the high level of detail at which Grotius knew the patristic texts, and how he moved in the intellectual circles of Paris. (shrink)

One of Russell's most important and interesting books which reconciles the materialistic tendency of psychology with the anti-materialistic tendency of physics.

ABSTRACT One simple but relatively neglected solution to the notorious coincidence puzzle of the statue and the piece of clay claims that the property of being a statue is a phase sortal property that the piece of clay instantiates temporarily. I defend this view against some standard objections, by reinforcing it with a novel counterpart-theoretic account of identity under a sortal. This proposal does not require colocation, four-dimensionalism, eliminativism, deflationism, or unorthodox theses about classical identity.

I introduce a new approach to fission puzzles called the Diversified Approach that proceeds by distinguishing different kinds of fission and assimilating each kind to a different ordinary phenomenon, such as breaking apart, replication, or part loss. To illustrate this approach, I apply it to the case of amoebic fission. The upshot is a novel account of amoebic fission according to which the dividing amoeba ceases to exist because it breaks apart. After developing this solution and highlighting some of its (...) advantages, I discuss briefly how the Diversified Approach can be extended to other varieties of fission. (shrink)

Many philosophers believe that the criteria of identity over time for ordinary objects entail that such objects are permanent members of certain sortal kinds. The sortal kinds in question have come to be known as substance sortal kinds. But in this article, I defend a criterion of identity that is suited to phasalism, the view that alleged substance sortals are in fact phase sortals. The criterion I defend is a sortal‐weighted version of a change‐minimizing criterion first discussed by Eli Hirsch. (...) I present this criterion and then argue that it withstands attempts to show that it is inferior to non‐phasalist rivals. (shrink)

We argue that the evil-god challenge is not an additional challenge for theists above and beyond the (much older) gap problem. One version of the evil-god challenge is merely a specific instance of the gap problem, and another is dependent on that specific instance of the gap problem. Therefore, the various solutions to the gap problem that theists have developed double as responses to the evil-god challenge, placing the evil-god challenge in a more vulnerable position than has been supposed.

In a recent article, P. Roger Turner and Justin Capes argue that no one is, or ever was, even partly morally responsible for certain world-indexed truths. Here we present our reasons for thinking that their argument is unsound: It depends on the premise that possible worlds are maximally consistent states of affairs, which is, under plausible assumptions concerning states of affairs, demonstrably false. Our argument to show this is based on Bertrand Russell’s original ‘paradox of propositions’. We should (...) then opt for a different approach to explain world-indexed truths whose upshot is that we may be morally responsible for some of them. The result to the effect that there are no maximally consistent states of affairs is independently interesting though, since this notion motivates an account of the nature of possible worlds in the metaphysics of modality. We also register in this article, independently of our response to Turner and Capes, and in the spirit of Russell’s aforementioned paradox and many other versions thereof, a proof of the claim that there is no set of all true propositions one can render false.

This article presents a distinct sense of ‘mechanism’, which I call the functional sense of mechanism. According to this sense, mechanisms serve functions, and this fact places substantive restrictions on the kinds of system activities ‘for which’ there can be a mechanism. On this view, there are no mechanisms for pathology; pathologies result from disrupting mechanisms for functions. Second, on this sense, natural selection is probably not a mechanism for evolution because it does not serve a function. After distinguishing this (...) sense fromsimilar explications of ‘mechanism’, I argue that it is ubiquitous in biology and has valuable epistemic benefits. (shrink)

Inquiry into the meaning of logical terms in natural language (‘and’, ‘or’, ‘not’, ‘if’) has generally proceeded along two dimensions. On the one hand, semantic theories aim to predict native speaker intuitions about the natural language sentences involving those logical terms. On the other hand, logical theories explore the formal properties of the translations of those terms into formal languages. Sometimes, these two lines of inquiry appear to be in tension: for instance, our best logical investigation into conditional connectives may (...) show that there is no conditional operator that has all the properties native speaker intuitions suggest if has. Indicative conditionals have famously been the source of one such tension, ever since the triviality proofs of both Lewis (1976) and Gibbard (1981) established conclusions which are in prima facie tension with ordinary judgments about natural language indicative conditionals. In a recent series of papers, Branden Fitelson has strengthened both triviality results (Fitelson 2013, 2015, 2016), revealing a common culprit: a logical schema known as IMPORT-EXPORT. Fitelson’s results focus the tension between the logical results and ordinary judgments, since IMPORT-EXPORT seems to be supported by intuitions about natural language. In this paper, we argue that the intuitions which have been taken to support IMPORT-EXPORT are really evidence for a closely related, but subtly different, principle. We show that the two principles are independent by showing how, given a standard assumption about the conditional operator in the formal language in which IMPORT-EXPORT is stated, many existing theories of indicative conditionals validate one, but not the other. Moreover, we argue that once we clearly distinguish these principles, we can use propositional anaphora to show that IMPORT-EXPORT is in fact not valid for natural language indicative conditionals (given this assumption about the formal conditional operator). This gives us a principled and independently motivated way of rejecting a crucial premise in many triviality results, while still making sense of the speaker intuitions which appeared to motivate that premise. We suggest that this strategy has broad application and an important lesson: in theorizing about the logic of natural language, we must pay careful attention to the translation between the formal languages in which logical results are typically proved, and natural languages which are the subject matter of semantic theory.

In this note we will discuss a new reflection principle which follows from the Proper Forcing Axiom. The immediate purpose will be to prove that the bounded form of the Proper Forcing Axiom implies both that 2ω = ω2 and that [Formula: see text] satisfies the Axiom of Choice. It will also be demonstrated that this reflection principle implies that □ fails for all regular κ > ω1.

Byerly has proposed a novel solution to the gap problem for cosmological arguments. I contend that his strategy can be used to strengthen a wide range of other theistic arguments as well, and also to stitch them together into a cumulative case for theism. I illustrate these points by applying Byerly’s idea about cosmological arguments to teleological arguments.

I present Ned Markosian's episodic account of identity under a sortal, and then use it to sketch a new model of the Trinity. I show that the model can be used to solve at least three important Trinitarian puzzles: the traditional ‘logical problem of the Trinity’, a less-discussed problem that has been dubbed the ‘problem of triunity’, and a problem about the divine processions that has been enjoying increased attention in the recent literature.

In the literature about harm, the counterfactual comparative account has emerged as a main contender. According to it, an event constitutes a harm for someone iff the person is worse off than they would otherwise have been as a result. But the counterfactual comparative account faces significant challenges, one of the most serious of which stems from examples involving non-harmful omitted actions or non-occurring events, which it tends to misclassify as harms: for example, Robin is worse off when Batman does (...) not give him a new set of golf clubs, but Batman has not harmed him. In this article, I will clearly state the counterfactual comparative account; state and explain this objection to the account; canvass several unsatisfactory responses; and attempt to show how the account can overcome the objection. This solution involves distinguishing between principles concerning the existence of harm and principles concerning attributions of responsibility for harm. (shrink)

Although the thesis that the moral better than relation is transitive seems obviously true, there is a growing literature according to which Parfit’s repugnant conclusion and related puzzles reveal that this thesis is false or problematic. This paper begins by presenting several such puzzles and explaining how they can be used in arguments for the intransitivity of better than. It then proposes and defends a plausible alternative picture of the behavior of better than that both resolves the repugnant conclusion and (...) preserves transitivity. On the threshold-based model of lexicality defended here, hedonic episodes whose intensity is above a certain point are lexically greater than those whose intensity is below it. The final sections argue that this model is independently plausible and can be defended from several important objections. (shrink)

‘Epistocracy’ is the name of a type of political power structure in which the power is held by the knowledgable—for example, by restricting the right to vote to those who can demonstrate sufficient knowledge. Though Plato and Mill defended epistocratic views, it has found few contemporary advocates. In a recent book, however, Jason Brennan argues that epistocratic power structures are capable of outperforming democratic ones. His argument is two-pronged: first, he argues that democratic procedures with universal suffrage allow poorly-informed voters (...) to pollute the electorate, and that doing so has negative policy-related consequences that are easily avoidable. Second, he argues that voting does not possess any non-intrinsic value, and so restricting suffrage to the educated does not result in a loss of status or standing for less well-educated persons in any meaningful way. I argue that epistocratic techniques are impossible to implement fairly, and represent an ineffective solution for the problems they are designed to solve. On these bases, I recommend rejecting it.

The phasalist solution to the classic puzzle of the statue and the piece of clay only works for some coincidence puzzles and not others. To address this limitation of phasalism, I develop a novel approach to coincidence puzzles that permits different kinds of coincidence puzzles to be solved in different ways, provided that each solution satisfies certain constraints inspired by the phasalist solution to the statue puzzle. I apply my approach to four different kinds of coincidence puzzles, and I argue (...) that it is no less plausible than rival approaches in the literature. (shrink)
