Meaning Solipsism says that it is possible for there to be a meaningful state without any other meaningful state. The meaning of such a solo meaningful state should be non-natural. The best strategy for establishing Meaning Solipsism is to argue for the determination of the meaning of a possible solo meaningful state via the set of entities the meaning of the state fits. Embracing merely possible and impossible entities is the most straightforward way to do so. Also, a good way (...) to honor analayticities the meaning of a solo meaningful state gives rise to is to insist on certain facts about impossible entities as non-negotiable brute facts. (shrink)

Inspired by Rick Grush's emulation theory, we reinterpreted a series of our neuroimaging experiments which were intended to examine the representations of complex movement, modality-specific imagery, and supramodal imagery. The emulation theory can explain motor and cognitive activities observed in cortical motor areas, through the speculation that caudal areas relate to motor-specific imagery and rostral areas embrace an emulator for amodal imagery.

This article provides a simple decision theoretic model in which elements of the world successively enter the decision maker’s scope and the state space expands over time, which is intended to be the closest correspondence to the standard subjective expected utility theory. We propose a dynamic consistency condition that after any expansion of the scope, the preference ranking should remain unchanged over acts to which the expansion is irrelevant. Together with other natural axioms, it characterizes a model in which the (...) decision maker’s belief extends over time in order that the marginal distribution of the new belief induced over the old state space coincides with the old belief. It is extended to encompass both expansion of scope and learning events, and we characterize the model with an additional property that the decision maker’s belief updating follows Bayes’ rule when she learns events.

DNA with a curved trajectory of its helix axis is called bent DNA, or curved DNA. Interestingly, biologically important DNA regions often contain this structure, irrespective of the origin of DNA. In the last decade, considerable progress has been made in clarifying one role of bent DNA in prokaryotic transcription and its mechanism of action. However, the role of bent DNA in eukaryotic transcription remains unclear. Our recent study raises the possibility that bent DNA is implicated in the “functional packaging” (...) of transcriptional regulatory regions into chromatin. In this article, I review recent progress in bent DNA research in eukaryotic transcription, and summarize the history of bent DNA research and several subjects relevant to this theme. Finally, I propose a hypothesis that bent DNA structures that mimic a negative supercoil, or have a right‐handed superhelical writhe, organize local chromatin infrastructure to help the very first interaction between cis‐acting DNA elements and activators that trigger transcription.

This article explores the diversity of the European idea of peace in the late thirteenth and early fourteenth centuries. In the late Middle Ages, a literary genre of “peace writings” emerged. Despite the ubiquitous academic interest in peace, however, late medieval scholastic conceptions of peace have hitherto escaped serious scholarly investigation. Drawing on Johan Galtung's classic typology of the idea of peace, this essay offers an examination of the discussions of Thomas Aquinas, Remigio de’ Girolami, and Dante on peace, which (...) not only illustrates the diversity of late medieval visions of peace but also argues that late medieval thinkers shared the recognition that temporal peace was possible: a significant departure from the Christian skepticism of this-worldly peace.

This paper is intended to offer an analysis of William of Ockham's and Guido Terreni's discourses on papal authority; it illuminates how their polemical use of the same authority -- Thomas Aquinas -- resulted in two diametrically opposed views. Guido Terreni's precarious understanding of Aquinas' commentary on the gospel of Luke stretched papal authority on doctrinal definition to the point of papal infallibility. Whereas, William of Ockham's use (and transformation) of Aquinas' idea of the object of explicit faith resulted in (...) a demand that every ecclesiastical authority should have thorough knowledge of the Christian faith and take every caution in doctrinal decision making. The paper shows that, in the context of polemics, Aquinas' ecclesiology was dissolved and different aspects of it were exaggerated by Terreni and Ockham. Thus, the paper also highlights Ockham's polemical skill in turning Aquinas -- the papalists' favourite authority -- against them. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Relationship between Theology and Canon Law: Another Context of Political Thought in the Early Fourteenth CenturyTakashi ShogimenPolitical thought and ecclesiology in the early fourteenth century have often been assessed as a series of responses to the question of the relationship between church and state. The conflict between Pope Boniface VIII and Philippe IV at the turn of the thirteenth and fourteenth centuries acutely demonstrated the conflict between the (...) spiritual and temporal powers. The conflict between Pope John XXII and the claimant to the imperial throne, Ludwig of Bavaria, also seems to have formed the historical background against which contemporary intellectuals expounded their political and ecclesiological thought. Two recent excellent textbooks on medieval political thought discussed the early fourteenth century from such a perspective and situated Marsilius of Padua and William of Ockham, along with their papalist adversaries, in this context. 1It is indeed a fair treatment of the period; however, it is not the only legitimate perspective. For instance, an alternative perspective can be developed through an examination of the Poverty Controversy between Pope John XXII and the Franciscans. This dogmatic dispute over the question of whether Christ and the apostles did not own anything individually or communally had a political dimension: it involved discussions on the nature of papal power over the church and resulted in the refinement of the idea of natural rights. 2 The dichotomy [End Page 417] between the papal and imperial camps can also mislead historical interpretation if the fact that each camp was not monolithic is overlooked. Just as Marsilius and Ockham embraced different political views in the alleged imperial camp, so the alleged papal ideologists did not always share the same views. It has even been argued that the doctrines propounded by “papalists” and “anti-papalists” were not irreconcilable but differed only in emphasis. 3 It is easy to see that the problem of Church and State is not the all-embracing concern of the period.What, then, are the possible benchmarks against which we can evaluate the political views of contemporary thinkers? This paper is intended to suggest that there is another context against which political thought and ecclesiology in the early fourteenth century may be assessed: that is, the relationship between theology and canon law. The contemporary polemicists’ view on the role that theology and canon law should play in an ecclesiastical dispute such as the Poverty Controversy largely determined their political or ecclesiological perspectives. To show this, I should like to compare, in the context of the poverty dispute, the ecclesiological views of two theologians in the so-called “papalist” and “anti-papalist” camps respectively: Guido Terreni and John Baconthorpe on the one hand, and William of Ockham and Michael of Cesena on the other. The comparison between Terreni and Baconthorpe will elucidate clearly that their contrasting attitude toward the role of canon law in contemporary ecclesiastical disputes determined the paradigms of their ecclesiologies, resulting in two entirely different ecclesiologies, save the fact that they were both aimed at defending the position of Pope John XXII on Franciscan poverty. The comparison between Ockham and Michael of Cesena will reveal how their contrasting views on the nature of the Poverty Controversy—theological or canonistic—determined not only the pattern of their defense of the Franciscan doctrine of poverty but also the development of their polemics.The relationship between theology and canon law had been a perennial problem ever since the latter had grown into an independent discipline. Scholastic theologians in the thirteenth century were critical of canon law studies. Bonaventure, for example, affirmed theology’s superiority over canon law: he wrote that theology questioned propter quid, whereas canon law enquired into [End Page 418] quia. Bonaventure, following Aristotle, asserted that there are higher and lower sciences, and what for the higher science, theology, is the conclusion of its enquiry is for the lower science, canon law, its starting point. 4 Thomas Aquinas considered that the intrusion of the decretalists into theological matters was disagreeable and ridiculous, 5 as did Roger Bacon. 6 These theologians’ comments testify to the antagonism between theologians and canonists in the thirteenth century. Lawyers, too, were fully aware of this situation, as seen... (shrink)

Mark Jago’s four arguments against Takashi Yagisawa’s extended modal realism are examined and shown to be ineffective. Yagisawa’s device of modal tense renders three of Jago’s arguments harmless, and the correct understanding of predications of modal properties of world stages blocks the fourth one.

Memory dynamics need both stable and unstable properties simultaneously. Hence memory dynamics cannot be simulated by chaotic itinerant dynamics alone, with no real world correspondence. Memory dynamics are constrained by both semantics and causalities in the embodied cognition.
