Rumination is a process of uncontrolled, narrowly focused negative thinking that is often self-referential, and that is a hallmark of depression. Despite its importance, little is known about its cognitive mechanisms. Rumination can be thought of as a specific, constrained form of mind-wandering. Here, we introduce a cognitive model of rumination that we developed on the basis of our existing model of mind-wandering. The rumination model implements the hypothesis that rumination is caused by maladaptive habits of thought. These habits of (...) thought are modeled by adjusting the number of memory chunks and their associative structure, which changes the sequence of memories that are retrieved during mind-wandering, such that during rumination the same set of negative memories is retrieved repeatedly. The implementation of habits of thought was guided by empirical data from an experience sampling study in healthy and depressed participants. On the basis of this empirically derived memory structure, our model naturally predicts the declines in cognitive task performance that are typically observed in depressed patients. This study demonstrates how we can use cognitive models to better understand the cognitive mechanisms underlying rumination and depression. (shrink)

This book offers a philosophical analysis of the main themes and problems of Aquinas' metaphysics of creation, centred on the concept of participation, the systematical meaning of which is examined in a critical discussion of the prevailing views of contemporary Thomas scholars.

The historiography of European liberalism has been dominated by large countries; this contribution focuses on the successful tradition of liberalism in the Netherlands. Just like German liberalism, the spirit of Dutch 19th-century liberalism was constitutional. It assumed that constitutional rules in a certain sense produced liberty, because liberty was not possible without a legally guaranteed context. Today the Dutch liberal party tries to combine classical liberalism with a mild populism, but recently the Pim Fortuyn upsurge of populism has hurt the (...) liberal party. A direct democratic style of politics has become popular among more right-wing liberals. Perhaps it is time to re-evaluate the 19th-century doctrinaire liberal traditions. Their anti-democratic ideas have been superseded, but the constitutional organization of liberty is as important as ever. (shrink)

The parameters governing our behavior are in constant flux, and capturing these dynamics in cognitive models remains a challenge. We demonstrate how a mapping between ACT‐R's model of declarative memory and the linear ballistic accumulator enables efficient estimation of memory parameters from data. The resulting estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals.

In lieu of an abstract, here is a brief excerpt of the content:Dei Filius I:On God, Creation, and ProvidenceRudi A. Te VeldeIn this essay, I want to share my impressions of the first chapter of the dogmatic constitution Dei Filius of Vatican I. It begins its declaration of the basic truths of Christian faith in a language which is similar, and probably intended to be similar, to that of a solemn confession of faith: "The holy, catholic, apostolic, and Roman church (...) believes and acknowledges that there is one true living God, creator and lord of heaven and earth."1 It reminds one, in some of its formulations, of the Nicene Creed, but with a remarkable difference: here, in the text of the constitution, the object of the confession is formulated as a proposition about God's existence.2 What is said is not, for example, "I believe in one God, the Father almighty"; but the Church believes and holds it to be true that there exists a God. One can notice a subtle shift from a confession of faith to the proclamation of a (rational) truth. The Pope, gathered with all the bishops of the Church, declares that there exists a God, the one and true living God, a doctrinal statement directed, by implication, against those who dare to deny the existence of God. The opening sentence of chapter 1 corresponds with its canon, which says that, "if anyone denies the one true God, creator and [End Page 823] lord of things visible and invisible: let him be anathema."3 Thus the constitution says that the "one, true living God" of the biblical faith exists, that this is a truth, and that, as consequence, the opposed thesis of atheism is false and must be rejected.Who is asserting this truth? Who is speaking and with which authority? The text leaves no doubt about the speaking subject. It is the Church, entitled to speak with authority about matters of faith, because it is the Roman Church, holy, catholic, and apostolic. The Church speaks, in the person of the pope, the legitimate successor of St. Peter, with authority granted to her by God himself through his Son Jesus Christ. In the preface preceding chapter 1 of the constitution, it is said that the Church is appointed by God to be "mother and mistress of nations." Hence:She can never cease from witnessing to the truth of God... and from declaring it, for she knows that these words were directed to her: "My spirit which is upon you, and my words I have put in your mouth, shall not depart out of your mouth from this time forth and for evermore"(Is 59:21).4This gives the pope, sitting in the chair of Peter, the authority of "teaching and defending Catholic truth and condemning erroneous doctrines."5 And the first thing to be declared, as part of the Church's task to proclaim the Catholic truth to all the nations, is to assert the existence of God against the error of atheism.It is important to understand the genre of a dogmatic constitution. It is a document in which the Church, by mouth of the pope together with the bishops, expounds the basic tenets of Christian teaching. The purpose of a dogmatic constitution is to reaffirm the basic truths of Christian doctrine, to clarify the fundamentals of faith in a message to the world. A constitution may be occasioned by actual developments in the world and society, but it speaks as it were from the standpoint of eternity. In case of the constitution Dei Filius, the addressee is the world of the mid-nineteenth century, a time of dominance of scientific reason, of materialism, naturalism, atheism, and not unimportantly, of current forms of idealistic pantheism (Georg Hegel, Friedrich Schelling, the influence of German Idealism in general); what the constitution especially stands opposed to [End Page 824] is the view of supernatural religion as being irrational. For this purpose it wants to reclaim reason and to overcome the disastrous gap between faith and (modern) rationality.The double program underlying the constitution—teaching the Catholic truth and condemning erroneous doctrines—reminds one of the Summa contra gentiles [SCG] of Thomas Aquinas.6 The...

De uitvoerige reactie van Sarot en Van den Brink waarin ze hun ‘Utrechtse’ positie in de wijsgerige theologie verduidelijken en verdedigen tegenover mijn vragen en scepsis, zou een uitvoerige beantwoording verdienen, uitvoeriger en grondiger dan het mij op deze plaats mogelijk is. Ik zal, ten eerste, ingaan op de kwestie van het realisme en, ten tweede, op het verwijt van ‘agnosticisme’ aan mijn adres.

Le présent travail se concentre sur les propriétés sémantico-syntaxiques du nom fait à l’exclusion, par conséquent, de ses usages énonciatifs, qui devraient constituer un volet complémentaire de la présente étude. La première partie du texte refait un bref historique de la définition des NSS et ajoute un nouvel argument à ceux de Adler pour appuyer l’idée que ces noms ne participent d’aucune « hiérarchie-être ». La seconde propose une répartition des NSS en trois sous-classes sur la base de critères syntaxiques, (...) qui font apparaître que toutes les structures spécificationnelles ne sont pas identiques, en dépit des apparences. Fait et les noms de « faits qualifiés » constituent une de ces sous-classes. Mais il est montré dans la troisième partie que fait occupe même dans sa propre sous-classe une position tout à fait unique. (shrink)

Contemporary theology commonly rejects the traditional 'Greek' reading of Exodus 3:14, according to which God reveals himself to Moses by the name of 'being' in favour of a more religious interpretation which sees in the name a confirmation of Gods enduring and liberating presence to his people. By means of an interpretation of Thomas Aquinas' reading of the Exodus-name in the Summa the author intends to show that Aquinas' account of the name is not guided by an exegetical and hermeneutical (...) interest but by a propoer speculative way of questioning, which can be formulated as follows: given the fact that God reveals himself to Moses under the name of being, how can this name - in what it signifies and how it signifies - be understood as a suitable medium by which God reveals himself to man. In the Summa-text Thomas gives three arguments why the name 'being' is the most appropriate name of God. It is argued that each of these arguments relates to a different aspect of the complex structure of God-in-his-revelation-to-man. Aquinas' account of the name of being is in accord with his analysis of the divine names, in which the tension between the res significata, the reality which is signified by a name, and the modus significandi, the human way of signifying, stands central. This tension returns in his analysis of the name 'being', where it clarifies the structure of revelation as a concealing presence of God to man. The implications of Thomas' reading for the notion of revelation exhibit some interesting similarities with the modern reading of Exodus inspite of the fundamental difference in theological method.

This article discusses Thomas Aquinas's view on the ‘utility’ of prayer in the light of the doctrine of creation ex nihilo. ‘Creatio ex nihilo’ means, among other things, that nothing can exist that is not caused by the universal power of God. The universal causality of creation implies that God cannot receive from the world or react to any activity on our part. This claim of divine immutability throws into question the intelligibility of prayer: does it make sense to pray (...) to God when his providence is certain and immutable? I argue that the God Thomas conceives is not the God of the ancient régime, the sovereign deity of absolute power who is in charge of everything; on the contrary, it is a God who grants the secondary causes within the world their own power and operation. The human activity of prayer belongs to this sphere of ‘second causes’, through which God realizes his providential plan. God's providence provides good things to us, one of which is the fulfillment of our prayers. (shrink)

In The Doctrine of God Dolf te Velde examines the interaction of method and content in three historically important accounts of the doctrine of God.

An evolutionary approach to historical linguistics can be enlightening when not only the mechanisms, but also the statistical methods are considered from neighboring disciplines. In this short paper, we apply survival analysis to investigate what factors determine the lifespan of words. Our case study is on post-classical Greek from the 4th century bc to the beginning of the 8th century ad. We find that lower frequency and phonetically longer lexemes suffer earlier deaths. Furthermore, verbs turn out to have higher survival (...) rates than adjectives and nouns. (shrink)

The results of an empirical study intoperceptions of the treatment of farm animals inthe Netherlands are presented. A qualitativeapproach, based on in-depth interviews withmeat livestock farmers and consumers was chosenin order to assess motivations behindperceptions and to gain insight into the waypeople deal with possible discrepancies betweentheir perceptions and their daily practices.Perceptions are analyzed with the help of aframe of reference, which consists ofvalues, norms, convictions, interests, andknowledge.The perceptions of the interviewed farmersare quite consistent and without exceptionpositive: according to them, (...) nothing is wrongwith animal welfare in livestock breeding. Theperceptions of the consumers we interviewed aremore divergent, but generally negative. Bothgroups show ambivalence as a result ofdiscrepancies between perceptions and behavior.Although the consumers share the impressionthat the living conditions of livestock animalsare far from optimal, most of them still buyand eat meat from the meat industry. Thefarmers believe the welfare of their animals isgood, but, as frequent defensive utterancesshow, they feel uncomfortable with expressed orunexpressed accusations of mistreating animals.The ways the respondents deal with thisambivalence were analysed by drawing ontheories of dissonance reduction and distancing devices.
