Riemer’s recent paper on the perception of time discusses a neglected yet important topic in the psychological literature: the consequences for psychology (and psychophysics) from the ‘anisotropy’ of time. The paper presents an argument that there are unique kinds of challenges for psychophysics from such temporal anisotropy: (a) Challenges because the psychological experience of time has temporal anisotropy and the physical concept of time does not have temporal anisotropy. (b) Challenges for experimental research which are unique to temporal anisotropy. (...) -/- Although it is important to consider temporal anisotropy, I think there are reasons to deny the force of both kinds of challenges. (shrink)

Salafism is one of the most important issues of the last few centuries. There are intense discussions on the issues related to Salafism, its emergence, how it was first used by whom and in what sense. Discussions about Salafism are sometimes experienced in relation to whether this concept corresponds to a mentality or to a sect, and sometimes this phenomenon is brought up in relation to a number of important names that have taken place in the history of Islamic thought. (...) Ibn Taymiyya (d. 728/1328) emerges as the most frequently mentioned name in this context. Therefore, in this article, we have examined how Salafism/Salafiyya concept is used in the works of Ibn Taymiyya who is accepted as the theorist and the most powerful representative of Salafism. We have discussed the issue in a comprehensive manner by including the concept of Salaf, which is one of the most used concepts of Ibn Taymiyya. When we consider Ibn Taymiyya's use of the concepts of Salaf and Salafiyya, the concept of Salaf is seen to be used much more than the concept of Salafiyya. Thus, the concept of Salaf in the thought of Ibn Taymiyya refers to the Islamic society that lived in the early centuries and the conception of religion revealed by this society. The concept of Salafiyya, however, appears to have been used in a way that reflects a mentality and a way of thinking rather than a particular school or sect.Summary: Sects are human made structures that emerged with the institutionalization of differentiations in the conception of religion. The production of systematic theology and fiqh, the formation of its own literature, its dissemination and dissociation from other systems of thought are the most important turning points for the emergence of sects. One of the most important variables that determine the formation process of sects is the mentality of sect. It is known that the sects come into the realm of existence when the mindsets with the implicit reference system become visible. Therefore, there is a mentality on which every sect is based, but not every mentality has come to the point of being a sect. While some mentalities have influenced different sects in different shades, some of them have been confronted with only one sect.In fact, Salafism is one of the ways of thinking which is a mindset and it is a subject of important debates about whether it is a sect. Although the use of salafiyya is seen in the literature in the past, the fact that Salafism felt its existence as a kind of religion or mentality was realized in the 18th and 19th centuries. It is also known that the discussions about the definition of Salafism have started since these periods. From the second half of the 20th century, Salafism began to take a place in the agenda of both the Islamic world and the West. This has naturally led to efforts to define Salafism. Thus, Salafism is subjected to attempts to identify and associate with structures, such as denomination, ideology, religious understanding and mentality. In this direction, it is seen that Salafism is tried to be defined by establishing close link with the structures, such as Ahl al-Sunnah, Ahl-i Hadith, Hanbalism and Wahhabism or by reducing them directly to one of these structures. Thus, Salafism is sometimes backed up to the early stages of Islamic thought and sometimes associated with multilayered structures, such as the Ahl al-Sunnah, which embodies many political-mythic and fiqh structures.In line with the efforts of defining Salafism, it is also seen that many names that have had a say in classical Islamic thought or have been mentioned in modern times have been brought to the agenda. In addition to the names, such as Ahmad ibn Hanbal, Ibn Taymiyya, Ibn Qayyim al-Jawziyya, the names of Emir al-Saneyani, Muhammad ibn Abd al-Wahhab, Muhammad al-Shawkani, Shaykh Abdulaziz ibn Baz and Muhammad Nasir al-din al-Albani are frequently mentioned in this process. It should be noted that there is a special place of Ibn Taymiyya among these names. Ibn Taymiyya took the place of both in history of Islamic thought and Ahl al-Hadith-Hanbalite tradition and made a name for himself in the context of many subjects. It is claimed that Ibn Taymiyya, who was the theorist of the Hanbalite conception of religion, and the missionary of the New Hanbalism, was also the founding figure and the most important representative of Salafism. In modern times, most of those who declare ideas about Salafism place Ibn Taymiyya at the center of Salafism and present him as the founding name of this mentality. However, the question of what kind of relationship between the mentality called Salafism and Ibn Taymiyya's world of thought and religion is not the subject of academic studies. However, the works of Ibn Taymiyya, who is an author of a very velocity, should be analyzed from this point of view and all kinds of words about Ibn Taymiyya-Salafism relationship should be left behind this effort. Our study, which aims to fulfill this gap, was designed to explain topics, such as whether the concept of salafiyya was used in the works of Ibn Taymiyya, whether and how the past was used, and the extent to which the meaning attributed to the salafiyya coincided with the current Salafism. Understanding of the concept of the salafiyya in the works of Ibn Taymiyya depends on the explanation of how the term salaf was derived and used by Ibn Taymiyya. When the works of Ibn Taymiyya are scanned, it is seen that he used the word salaf much more than the word salafiyya. In fact, the word of salafiyya, which Ibn Taymiyya has rarely included, has been placed in some places in a way that refers to the meaning field of the word salaf. When we consider the use of the word salaf in the works of Ibn Taymiyya, we first see the generations who lived in the early historical periods of Islamic thought and the conception of religion which these generations have revealed. Other names that have taken place in the history of Islamic thought have similar opinions about the generation of the predecessors and the religious understanding of this generation. In other words, according to the general opinion of the predecessor, especially the first three centuries came to mind. However, it is seen that Ibn Taymiyya made some attempts to periodize both the generation of the predecessors and to define the understanding of religion of this generation. Nevertheless, Ibn Taymiyya could not provide a clear picture on this issue, and he occasionally contradicted his findings regarding his involvement in the predecessor generation. Nevertheless, he generally adopted generalizations and an attitude to limit the meaning of the predecessor to the first generations. The word salafiyya, which Ibn Taymiyya placed on the meaning of the word salaf, is used less compared to the word salaf and is given in more complete terms. This indicates that the main factor that influenced Ibn Taymiyya's salafi thought was salaf, not salafiyya as a systematic structure. These findings make it necessary to reconsider the claims of Salafism being a sect and it is being represented at the time of Ibn Taymiyya. (shrink)

I wrote this essay for three reasons. First, in proofreading The Reconstruction of the Humanistic Spirit, I felt that this great pile of articles contained only general discourses on the social and cultural problems of China and the Western world but did not mention my own philosophical position and religious faith. Although the pattern and style of the essays in this book might excuse this defect, I was afraid that some of my readers would find it difficult to grasp the (...) main themes of thought in the book. Therefore, I wanted to write an article to compensate a bit for this shortcoming. Second, for many years, in teaching courses on Chinese or Western philosophy, I have been used to following the general lecturing method of university professors who stress the objective introduction of philosophical doctrines to enrich students' knowledge.

Els estudis sobre la filosofia de Wittgenstein darrerament han posat de manifest la potència del seu pensament sobre qüestions morals, estètiques i, fins i tot, polítiques, a més dels problemes lògics, lingüístics o epistemològics que va plantejar. Les qüestions estètiques van ocupar bona part del seu treball en filosofia i, com mostren els treballs recollits en aquest volum, la vinculació entre el pensament filosòfic de Wittgenstein, les qüestions estètiques i la seua pròpia biografia és tan estreta que cal considerar-la com (...) un dels pòrtics d’entrada que ens permeten endinsar-nos en l’univers de la filosofia wittgensteiniana.

We show that the variety of n -dimensional weakly higher order cylindric algebras, introduced in Németi [9], [8], is finitely axiomatizable when n > 2. Our result implies that in certain non-well-founded set theories the finitization problem of algebraic logic admits a positive solution; and it shows that this variety is a good candidate for being the cylindric algebra theoretic counterpart of Tarski’s quasi-projective relation algebras.

SummaryIf you know you can recognise positive instances of a property, can you use this knowledge so as to be able to recognise also its negative instances? This is the question to be adressed.

Spatial evolutionary game theory explains how cooperative traits can survive the intense competition in biological systems. If the spatial distribution allows cooperators to interact with each other frequently, the benefits of cooperation will outweigh the losses due to exploitation by selfish organisms. However, for a cooperative behavior to get established in a system, it needs to be found initially in a sufficiently large cluster to allow a high frequency of intracooperator interactions. Since mutations are rare events, this poses the question (...) of how cooperation can arise in a biological system in the first place. We present a simple model which captures two concepts from genetics that can explain how evolution overcomes the emergence problem. The first concept is, often in nature, a gene may not express its phenotype except under specific environmental conditions, rendering it to be a “silent” gene. The second key idea is that a neutral gene, one that does not harm or improve an organism’s survival chances, can still spread through a population if it is physically near to another gene that is positively selected. Through these two ideas, our model offers a possible solution to the fundamental problem of emergence of cooperation in biological systems. (shrink)

Open peer commentary on the article “What Can the Global Observer Know?” by Diana Gasparyan. Upshot: I introduce some distinctions that I hold to be useful for understanding the global observer problem and then sketch a hypothetical scenario that suggests the existence of an observer that is as good as a global one.

The theme "Dostoevsky and Nietzsche" is one of the most important for understanding the meaning of the abrupt changes that took place in European philosophy and culture at the turn of the nineteenth century. This epoch is still a puzzle: it was a flourishing period for the creative powers of European humanity and at the same time the beginning of the tragic "breakdown" of history that gave birth to two world wars and unprecedented calamities, the consequences of which Europe has (...) been unable to overcome, as shown by the uninterrupted decline of traditional culture, which began at the end of World War II and still continues today. In this epoch, as in the eighteenth century, which culminated in the Great French Revolution, philosophy came out of the study onto the street and became a practical force that steadily undermines the existing order of things; in a certain sense it was precisely philosophy that called forth the catastrophic events of the first half of the twentieth century, which had as never before a metaphysical subtext. At the center of the upheaval that engulfed absolutely all forms of European civilization and culminated, at the beginning of the twentieth century, with the rise of nonclassical science, "nonclassical" art, and "nonclassical" philosophy, was the problem of man, his essence, the meaning of his existence, and the problem of man's relations with society, the world, and the Absolute. It is no coincidence that M. Scheler used the term "anthropological turn" to describe the changes that occurred in philosophy in this epoch; what had long been implicit in philosophy and art and in paradoxical fashion had become apparent even in the new scientific theories, was now made clear: man is not a tiny "atom" in boundless and alien being, but the starting point for all suppositions, the primary field of meanings from which any philosophical or scientific "questioning" must depart.

In our discussion on the development of political consciousness in the Chinese people in the past one hundred years, we will focus on the upward development made in the course of the reconstruction of the nation. If we simply study the historical facts, the past one hundred years are tragic. But if we study the spirit of the people during this period, we cannot but recognize that the Chinese people have never given up and that they have been constantly struggling (...) upward. In the history of their struggle the Chinese people have gone astray many times; otherwise, the country would not be what she is now. But from mistakes corrections are made, thus eliminating the possibility of repeating the same mistakes. This is what we call the instructional value of history. From this view, the Chinese people are presently undergoing a crisis in which they seem to have nothing to support and nothing to possess. But spiritually and ideologically, the Chinese people possess the most substantial "have," one that no other people or nation of the world has had. This most substantial "have" is the historical experience gained through the continuous upward struggle against failures in the reconstruction of their nation. This historical experience can be valuable only when it has become the self-consciousness of the people and their future generations. This self-consciousness is related mainly to the development of political consciousness in the Chinese people in the past hundred years. (shrink)

Purpose. The purpose of the research is to define certain interaction features between a human and the urban environment in the global world. Theoretical basis. The study in based on the investigations of contemporary researchers in social philosophy and urban science, as well as social scientists of Chicago School. Originality. The originality of the research is to analyze the "human-urban space" system in terms of the influence of local space of the global world on the human identity formation and preservation. (...) Conclusions. Modern information technologies have significantly contributed into changes in the culture, society, individual consciousness and perception. They have given them absolutely global character and reorganized the value and standard system of the individual. As a result, it caused the identity crisis, so typical of the postindustrial society. Thus, one of the possible ways to overcome the crisis is to harmonize the interaction in the "human-urban space" system as an area of individual space of human social and cultural identity. (shrink)
