The paper is aimed at rationalizing relationships between the structure of inorganic compounds in condensed phases and their melting and boiling points. It is documented that the main factor governing both points is their molecular or polymeric nature. In case of polymeric ionic compounds, the higher actual charge bearing by the ions involved, the higher their melting/boiling points. In case of covalent polymers, the value of both points increases with polymer dimensionality and with the number and energy of the respective (...) covalent bonds. In case of molecular compounds, both points depend on the weight and shape of molecules, the presence of hydrogen bonds, and electric quadrupole moment. (shrink)

The paper is aimed at defining reduction, oxidation, and redox reactions based both on the oxidation number and charge changes in reacting species. It is rationalized that the processes of oxidation and reduction, usually occurring simultaneously, can occur also as independent processes. It is explained that in balancing chemical equations of redox reactions the “gain” or “loss” of electrons should be understood as changes in oxidation number. A formal expressions “+n e−” and “−n e−” represent in reality a decrease and (...) increase in oxidation number by n units, respectively. (shrink)

The paper is aimed at the issues of oxidation state determination and limiting values. The possibility of existence of compounds containing an atom with the oxidation number beyond the current common values, i.e., below −IV and above +VIII are discussed. Three principal modes of preparation of compounds with the oxidation number exceeding VIII, electrochemical anodic oxidation, photoionization, and nuclear β-decay, are evaluated. Failure to prepare compounds containing an atom with the oxidation number below −IV is rationalized. The paper provides an (...) opinion on uncertainties in oxidation state determination in three kinds of compounds: binary compounds, nitrosyl complexes, and compounds containing mutually bonded atoms of the same element. The questions are discussed from the viewpoint of correlation of “man-made” quantities and objective, experimentally obtainable data. (shrink)

Este artigo retoma os conceitos de poder disciplinar e biopoder em Michel Foucault para, então, fazer um diagnóstico do contexto pandêmico causado pela Covid-19. Ao se considerar que mais da metade da população mundial foi orientada ao isolamento social, bem como à alteração de hábitos cotidianos a fim de diminuir a propagação do vírus SARS-CoV-2, é possível perceber em Foucault as medidas da técnica disciplinar e da tecnologia biopolítica, ambas direcionadas à preservação da vida da população. Considera-se que o poder (...) disciplinar e o biopoder funcionam na atual pandemia num contexto inédito, marcado pelo avanço tecnológico. (shrink)

Hannah Arendt plačiai žinoma kaip filosofė, kuri mėgino reabilituoti senovės graikų politikos sampratą. Remiantis Žmogaus būklės skaitymu, Arendt paprastai laikoma „graikofile“, jai prikišama „Atėnų nostalgija“. Sunku paneigti Arendt simpatijas graikams – ji iš tiesų atsigręžė į atėniečių politikos supratimą, bandydama jame iškristalizuoti kertinius autentiškos politikos elementus. Vis dėlto ši interpretacija yra pernelyg vienpusiška. Didžiausius nuopelnus politikos suvokimo srityje Arendt priskiria ne graikams, o romėnams. Pastarieji žymiai geriau sprendė politikos stabilumo, tęstinumo ir tvarumo problemą. Visą dėmesį sutelkiant į veiksmą, spontaniškumą ir (...) nepaprastus žygdarbius, kyla grėsmė destabilizuoti ir „išcentruoti“ politinės bend­rijos gyvenimą. Romėnai, įvesdami tokias sąvokas kaip tradicija, autoritetas, steigties (įkūrimo) šventumas, teisė (lex), taip pat pabrėždami politinę atleidimo ir pažado reikšmę, atveria graikams svetimą politinės sedimentacijos plotmę. Ši plotmė suteikia būtinus saugiklius, be kurių tvari politinė egzistencija yra neįmanoma. (shrink)

The collection of papers assesses the impact of the reception of Averroist ideas on philosophy between the 15th and 17th century in the Latin West. Most of the articles in the volume were presented at the conference "Averroism between the 15th and 17th century", which was held on 9th-10th November, 2016 by the Department of Philosophy, Faculty of Arts at Palacký University, Olomouc, the Czech Republic. The contributors explore the influence of Averroes, identify the difficulties in the interpretation of his (...) works, and study his followers and critics in the Latin, Hebrew, and Byzantine traditions"--Back cover.

Aristotle tells us that in order to develop virtue, one needs to come to love and hate the right sorts of things. However, his description of the virtuous person clearly privileges love to hate. It is love rather than hate that is the main driving force of a good life. It is because of her love of knowledge, truth and beauty that the virtuous person organizes her life in a certain way and pursues these rather than other things (such as (...) pleasure). When hate comes into the picture, it is merely an unavoidable consequence of loving those noble and beautiful things. The virtuous person hates things that are contrary to her values, but does not concentrate on them, much less constructs her life in the pursuit of their destruction. But why privilege love over hate in this way? Why could not a good (happy) and virtuous life be a life driven primarily by hate (in particular, one aimed at eradicating what one (correctly) considers shameful and evil)? Without appealing to any consequences or harmful effects that hate might have on other People, the paper gives two answers to this question. First, allowing hate (rather than love) to dominate one’s life would undermine the right relationship between the two parts of the soul (the rational and the non-rational one) that Aristotle recognizes. Virtue involves establishing the right kind of internal ordering of one’s soul and this cannot be done if one’s soul is dominated by hate. Second, hate has negative cognitive effects insofar as it renders one insensitive to the beauty of human nature and behavior and actively precludes one from acquiring knowledge and understanding. Accordingly, if a good life is a life that involves virtue and knowledge, a life fueled by hate cannot but fall short of that ideal. (shrink)

Two sextants constructed for Tycho Brahe are preserved in the National Technical Museum in Prague. One was constructed by Erasmus Habermel, the other by Jost Bürgi. Both were made in the year 1600. To overcome the observational errors, several improvements were made in the construction of these instruments, especially in the case of Bürgi's sextant. It would appear both from these instruments and from his tables of sines that Tycho wanted to reduce the errors to one minute of arc. A (...) replica of Bürgi's sextant, which is currently under construction, will allow the accuracy of the instrument to be tested. (shrink)

The presented paper focuses on the analysis of strategic documents at the level of the European Union concerning the regulation of artificial intelligence as one of the so-called disruptive technologies. In the first part of the article, we outline the basic terminology. Subsequently, we focus on the summarizing and systemizing of the key documents adopted at the EU level in terms of artificial intelligence regulation. The focus of the paper is devoted to issues of personal data protection and cyber security (...) included in these strategic documents. The final part contains recommendations for future research and evaluation of its key features. (shrink)

I argue that on Aristotle’s account practical thinking is thinking whose origin (archē) is a desire that has as its object the very thing that one reasons about how to promote. This feature distinguishes practical from productive reasoning since in the latter the desire that initiates it is not (unless incidentally) a desire for the object that one productively reasons about. The feature has several interesting consequences: (a) there is only a contingent relationship between the desire that one practically reasons (...) about how to satisfy and the action one decides on; (b) practical thinking and action cannot be separated from the agent, whereas productive thinking and production can be outsourced to someone else. The view has consequences also for the distinction between action and production. Finally, I illustrate the usefulness and correctness of my account of practical thinking by using it to shed new light on Aristotle’s claim that the virtuous agent must decide on her virtuous actions ‘for themselves’.

In this paper, I argue that the widely held view that Aristotle's vicious agent is a principled follower of a wrong conception of the good whose soul, just like the soul of the virtuous agent, is marked by harmony between his reason and non-rational desires is an exegetical mistake. Rather, Aristotle holds – consistently and throughout the Nicomachean Ethics – that the vicious agent lacks any real principles of action and that his soul lacks unity and harmony even more than (...) the soul of the uncontrolled agent.

De Franse schrijver en denker Albert Camus (1913-1960) was een van de voornaamste intellectuele stemmen van de twintigste eeuw. Zijn vertolking van de ervaringen van absurditeit en revolte in essays, romans en toneelstukken vonden brede weerklank in het naoorlogse Europa en daarbuiten. Camus’ scepsis ten aanzien van de grote ideologieën, zijn gevecht met het nihilisme en zijn onvermoeibare verdediging van het leven en de menselijkheid zijn nog altijd voor velen een bron van inspiratie. Dit boek geeft een beknopt overzicht van (...) het leven en de belangrijkste werken van Camus. Maar vooral wordt de ontwikkeling van zijn denken van absurditeit naar revolte geschetst in een historische en literair-wijsgerige context. Daarbij komt ook de vraag naar de overkoepelende eenheid van zijn werk aan bod. (shrink)

Background and AimsEnd-of-life discussions can be difficult for seriously ill adolescents and young adults. Researchers aimed to determine whether completing Voicing My CHOiCES —a research-informed advance care planning guide—increased communication with family, friends, or health care providers, and to evaluate the experience of those with whom VMC was shared.MethodsFamily, friends, or HCPs who the AYAs had shared their completed VMC with were administered structured interviews to assess their perception of the ACP discussion, changes in their relationship, conversation quality, and whether (...) the discussion prompted changes in care. Open-ended responses underwent thematic analysis.ResultsOne-month post-completion, 65.1% of AYA had shared VMC completion with a family member, 22.6% with a friend, and 8.9% with an HCP. Among a sample of respondents, family and friends reported a positive change in their relationship with the AYA. Participant descriptions of the experience fell into five themes: positive experience, difficult experience, appreciated a guide to facilitate discussion, provided relief, and created worry/anxiety. Only 1 HCP noted a treatment change. Family, friends, and HCP did not think the AYA would have discussed EoL preferences without completing VMC.ConclusionsVMC has potential to enhance communication about ACP between AYA and their family and friends, though less frequently with HCPs. Participants reported a positive change in their relationship with the AYA after discussing VMC, and described experiencing the conversation as favorable, even when also emotionally difficult.

The paper defends three claims about Aristotle’s theory of uncontrolled actions (akrasia) in NE 7.3. First, I argue that the first part of NE 7.3 contains the description of the overall state of mind of the agent while she acts without control. Aristotle’s solution to the problem of uncontrolled action lies in the analogy between the uncontrolled agent and people who are drunk, mad, or asleep. This analogy is interpreted as meaning that the uncontrolled agent, while acting without control, is (...) still in possession of her knowledge but she is unable to use it as knowledge due to the temporary disablement of her reason by appetite. Due to this disablement, the uncontrolled agent is temporarily unable to be motivated to act by her knowledge and acts merely on her appetite. Second, I argue that the second part of NE 7.3 provides an analysis of the particular mental state from which the uncontrolled action issues. Its central passage is a description of the uncontrolled agent’s state of mind before the uncontrolled action and not, as it has been traditionally understood, a description of her state of mind during the uncontrolled action. Third, I argue that, on Aristotle’s view, the transition from the state before the uncontrolled action to the state in which the agent already acts without control does not involve any psychological state that would constitute the agent’s choice to abandon her decision and give in to her desires but proceeds on a purely physiological level.

I defend two main theses. First, I argue that Aristotle’s account of voluntary action focuses on the conditions under which one is the cause of one’s actions in virtue of being (qua) the individual one is. Aristotle contrasts voluntary action not only with involuntary action but also with cases in which one acts (or does something) due to one’s nature (for example, in virtue of being a member of a certain species) rather than due to one’s own desires (i.e. qua (...) individual). An action can be attributed to one qua individual in two distinct ways depending on whether one is a rational or a non-rational animal. One is responsible for one’s action in both cases, but only in the former case is one also responsible for being the sort of individual that performs it. Aristotle also distinguishes two ways in which an action can be compelled while still being an action of the agent. In the first case, one is compelled by (physically) external forces or circumstances to act against one’s internal impulse. In the second case, one is compelled to act on (internal) impulses that are fixed by one’s nature against one’s own individual impulse. This latter kind of compelled action is only possible in the case of rational agents. Secondly, I argue that Aristotle’s conception of what it is to be a cause of an action inevitably brings in certain normative features which support evaluative judgments and the practice of praise and blame. On Aristotle’s view, any goal-directed behavior that is properly attributable to an individual is (normally) subject to standards that pertain to behavior of that sort. At the most basic level, these standards establish what counts as a successful realization of the goal that one aims at. Thus even in the case of non-rational animals (or children), one can judge the success of what they are doing and encourage (or discourage) similar behavior by praise or blame. These standards are applicable to one’s conduct simply insofar as one is the controlling origin (or efficient cause) of one’s action qua individual. In the case of rational agents the practice of praise and blame can involve a further normative layer since they can be praised or blamed not only for acting in a certain way so as to encourage or discourage them with a view to the future, but also for being – and having become – individuals of a certain sort. Nevertheless, the applicability of such evaluative judgments and of praise and blame is still warranted by one’s being the controlling origin of one’s actions qua the individual one is (in this case, qua rational individual).

This paper examines Hannah Arendt’s account of the relationship between politics and morality. Many critics have argued that Arendt’s conception of political action lacks any moral foundations, while others have tried to focus on her understanding of thinking as a normative source of her ethics. In contrast to these views, I present an alternative explanation and argue that the sources of Arendt’s political ethics are located neither in the faculty of thinking nor in extrapolitical moral norms or rules, but in (...) the ontological conditions of action, specifically worldliness, natality and plurality. This interpretation allows us to make sense of Arendt’s fragmented, unsystematic accounts of the various virtues and moral dispositions required for authentic politics: courage, responsibility, care, respect, moderation, solidarity and gratitude. In particular, an inquiry into the ontological sources of political ethics provides a solid normative grounding for the two moral dispositions—promise and forgiveness—that form an explicit “moral code” of political action for Arendt.

I argue that, for Aristotle, virtue of character is a state of the non-rational part of the soul that makes one prone to making and acting on decisions in virtue of that part’s standing in the right relation to (correct) reason, namely, a relation that qualifies the agent as a true self-lover. In effect, this central feature of virtue of character is nothing else than love of practical wisdom. As I argue, it not only explains how reason can hold direct (...) authority over non-rational desires but also why Aristotle defines virtue of character as hexis prohairetikē. (shrink)

The paper addresses the following question: why do human beings, on Aristotle’s view, have an innate tendency to badness, that is, to developing desires that go beyond, and often against, their natural needs? Given Aristotle’s teleological assumptions (including the thesis that nature does nothing in vain), such tendency should not be present. I argue that the culprit is to be found in the workings of rationality. In particular, it is the presence of theoretical reason that necessitates the limitless nature of (...) human non-rational desires. (shrink)
