From the time of its birth, Popper 's theory of falsifiability has been fiercely criticized from various viewpoints. In the author's view, however, those various criticisms all have the same root in their assumption that a falsification must be certain and conclusive. As the theory of falsifiability has never had such an assumption, it is the source of misunderstanding. By discarding it, we can reply to every criticism and thereby clarify the role of falsifiability in our search for better knowledge; (...) that is, it makes our attitude open to a yet unknown world.

Involuntary eye movement during gaze fixation, referred to as fixational eye movement, consists of two types of components: a Brownian motion like component called drifts-tremor and a ballistic component called microsaccade with a mean saccadic amplitude of about 0.3° and a mean inter-MS interval of about 0.5 s. During GZ fixation in healthy people in an eccentric position, typically with an eccentricity more than 30°, eyes exhibit oscillatory movements alternating between centripetal drift and centrifugal saccade with a mean saccadic amplitude (...) of about 1° and a period in the range of 0.5–1.0 s, which has been known as the physiological gaze-evoked nystagmus. Here, we designed a simple experimental paradigm of GZ fixation on a target shifted horizontally from the front-facing position with fewer eccentricities. We found a clear tendency of centripetal DRT and centrifugal MS as in GEN, but with more stochasticity and with slower drift velocity compared to GEN, even during FEM at GZ positions with small eccentricities. Our results showed that the target shift-dependent balance between DRT and MS achieves the GZ bounded around each of the given targets. In other words, GZ relaxes slowly with the centripetal DRT toward the front-facing position during inter-MS intervals, as if there always exists a quasi-stable equilibrium posture in the front-facing position, and MS actions pull GZ intermittently back to the target position in the opposite direction to DRT.

A robot that is easy to teach not only has to be able to adapt to humans but also has to be easily adaptable to. In order to develop a robot with mutual adaptation ability, we believe that it will be beneficial to first observe the mutual adaptation behaviors that occur in human–human communication. In this paper, we propose a human–human WOZ (Wizard-of-Oz) experiment setting that can help us to observe and understand how the mutual adaptation procedure occurs between human (...) beings in nonverbal communication. By analyzing the experimental results, we obtained three important findings: alignment-based action, symbol-emergent learning, and environmental learning. (shrink)

The third century of the hegira represents an extremely important period in terms of the formation process of Islamic sciences and the acquirement of the identity of a systematic school of fiqh madhhabs. In terms of the Zaydiyya madhhab, this century has an identity that affects the next period in terms of both political and scientific studies. Because in this period, the scholars of the madhhab like Kāsim al-Rassî (d. 246/860), Ahmad b. Isā (d. 247/861) and Yahyā b. al-Husayn (d. (...) 298/911), who were in a leading position both in politics and in sciences such as kalām, hadith and fiqh, emerged. Kāsim al-Rassî, who was accepted as the star of the Ahl al-Bayt by Zaydî sources in the first period, was presented as the Plato of Muslims by orientalists in modern studies. The main reason why today's studies on him are mostly about the history of sects and theology, most of Rassî's works are about kalām. However, Kāsim al-Rassî is an important name in the science of fiqh and İslamic legal theory as well as in the science of kalām. According to Abī Tālib Nātik bi’l-Hakk (d. 424/1033), one of the important jurists of the Zaydiyya madhhab, Rassî was a scholar who came to the fore with his ability in fiqh issues; in order to see his ijtihād method, his skill in furû al-fiqh, his mastery in using hadiths and knowing the disagreements of scholars, ‘‘Masā’il al-Dja’far b. Muhammad and Abd Allah b. Hasan” should be consulted. Rassi's epistles named Kitab al-Nāsikh wa’l-Mansūkh, Kitab al-tahāra, Kitab al-salāt al-yevm ve al-Laylā and Kitab al-menāsik are important studies on fiqh that have survived to the present day. In addition, Mueyyed-Billah (d. 411/1021) compiled Kāsim al-Rassî’s and Yahya b. al-Husayn's views on fiqh in his work named al-Tecrîd. Kāsim al-Rassî's views on fiqh are also determinative in later fiqh books such as Tahrîr, al-Cāmi' al-Kāfi, al-Intisār and al-Azhar. In time, the emergence of a jurisprudence sect named Kāsimiyya in Zaydiyya, referring to his name, is also important in terms of revealing his position. Although Rassî's views on fiqh have been referred to a number of studies in our country, no independent study has been found that deals with his views on fiqh. However, considering both of his works on fiqh that have survived to the present day and the early works in which his views are compiled, it is obvious that Kāsim al-Rassî's views on fiqh deserve an independent works. The aim of this study is to reveal Ressî's position within the madhhabs and his perspective on fiqh in general. In this context, in the study, the period in which Ressî lived, his life and works were briefly mentioned, and then the basic views of the fiqh, especially in the field of worship, were discussed in outline.

al-Qurṭubī (d. 671/1273) was a scholar of tafsīr, ḥadīth and fiqh. He experienced both Western and Eastern civilizations in the geography of Andalusia and Egypt, respectively. In his famous Tafsīr called al-Jâmi li-Aḥkâm al-Qur’ān, al-Qurṭubī comparatively explained and interpreted all legal verses. Also, in addition to exploring the spesific legal rulings denoted in the Qur’ān and the Sunnah, al-Qurṭubī has largely interpreted the legal norms regarding the issues of jurisprudence. By doing this, al-Qurṭubī contributed to the formation and development of (...) a civil codification activity under a kazuistic format. The casuistic structure of the legal exegesis of the Qur’ān is anlaysed in terms of the form and content in the sample of al-Jâmi. Therefore, neither the similarity or similarity of the schools of the legal exegesis of Qur’ān and of the legal schools nor the disciplines of positive law, but their kazuistic structures, which systems they built and which interpretation methods and techniques they operated on this basis, were evaluated in terms of their original structure. In this direction, the article emphasizes that the casuistic structure of the legal exegesis of Qur’ān is established on and by the Prophet’s sayings and practices. Although, it has been observed that it is a unique tradition, both as form and content, and that the interpretation means are identified with its own unique structure, it has been concluded that the casuistic method is not one of the fundamental elements of both this tradition and Islamic legal thought. This means that the casuistic method is always a tool that can be changed and transformed according to the conditions of time and space.Summary: As it is stated in al-Isrāʾ 17/106: “And (it is) a Qur’ān which we have separated (by intervals) that you might recite it to the people over a prolonged period. And we have sent it down progressive.”, the Qur’ān is revelaed in about twenty-three years by taking into consideration the sociocultural positions of its interlocutors. The Prophet Muḥammad explained the Qur’ān by the virtue of the ayah: “(We sent them) with clear proofs and written ordinances. And We revealed to you the message (i.e. that you may make clear to the people what was sent down to them and that they might give thought.” (an-Naḥl 16/44). Of course, there is no subject integrity in this Qurānic chronology-which also reflects life. As a matter of fact, the issues related to individual and society have been independently analyzed by a casuistic/case-based method and ruled in accordance with the intention of Allāh. It can be seen that the ayahs “They ask you about wine and gambling. Say, ‘In them is great sin and (yet, some) benefit for people. But their sin is greater than their benefit.’ And they ask you what they should spend. Say, ‘The excess (beyond needs).’ Thus Allāh makes clear to you the verses (of revelation) that you might give thought.” (al-Baqara 2/219) and other ayahs such as (al-Baqara 2/186; al-Nisāʾ 4/176; al-Anfāl 8/1) reflect the casuistic method in terms of form and content. This can also be exemplified by the Sunna. For example, when the question “Is it permissible to perform ablutions with sea water?” was posed to Messenger of Allāh. He said that “It’s water is clean and his dead (fish) are lawful “(Abū Dāwūd, “Ṭaḥāra”, 41). By this answer, the Prophet Muḥammad indeed ruled and established a general rule.It can be said that this early example table formed the basis of the legal exegesis of the Qur’ān in terms of origin, source and application, and that its shape and content are often immanent in the examples it contains. In this article, based on the prophetic period, the legal exegesis of the Qur’ān and casuistic structure has been studied with an analytical and critical approach. Again, because the casuistic method is one of the universal concepts of east-west science and cultural life, an interdisciplinary approach was exhibited in this study. The roots of the casuistic method date back to 5000 BC and the legal systems of the society and states of antiquity are examined from this method. This method is chosen and used in the legal exegesis of the Qur’ān. However, this study does not analyse the sameness or the similarity of the legal exegesis of the Qur’ān and the legal schools nor the positive law disciplines, but the casuistic structures used by these, the systems they have built on this basis and the interpretation methods and techniques they have been used and analyzed in terms of their originality.In effect, the article embodies the Qur’ānic exegesis called al-Jâmi li-Aḥkâm al-Qur’ān by al-Qurṭubī (d. 671/1273), a scholar of tafsīr, ḥadīth and fiqh. In addition to the works of the aḥkām al-Qur’āns, which deal with the interpretation of the ayahs related to the subjects of ʿibādāt, muʿāmalāt ve ʿuḳūbāt, many other works have been used in parallel with the development of the legal exegesis of the Qur’ān. al-Qurṭubī, who comparingly explained the legal verses in his tafsīr, investigated the aspects of the Qur’ān and Sunna that indicate the aḥkām, generally interpreted the existing legal norms within the framework of evidence and introduced his own opinions and etasblished his ijtihād. Thus, he benefited from the tafsīr accumulation and contributed to the formation and development of a civil legalization activity with casuistic format. As a matter of fact, the casuistic/case-based method has been used as a codification/tadwīn technique by Western and Eastern legal disciplines and systems. The casuistic method covers both concrete event and abstract ruling methods. In the casuistic method, which is fact-based event, the laws are organized according to all possible events that can be experienced. On the other hand, the abstract method, which is defined as the abstract ruling method, aims to organize the laws in a general and abstract framework. In the article, it is stated that the legal exegesis of the Qur’ān contains both concrete and abstract dimensions in its own way. It has been emphasized that the legal exegesis of the Qur’ān is based on divine revelation (waḥy) and that it is separated from human law as its origin and source, and that this feature is its most faithful characteristic. On this basis, the legal exegesis of the Qur’ān is a separate scholarly tradition and has its own definition, subject and purpose. Its original structure and function have been noted. As a matter of fact, the subject and purpose of the legal exegesis of the Qur’ān always require the tafsīr and taʾwīl of the legal verses having regard to the Qur’ān and Sunna. It is also necessary for the purpose of investigating the ways in which nuṣūṣ (an explicit statement upon which a ruling is based) can refer to the provisions and to resolve the issues related to individuals and society. As a matter of fact, the legal verses function as a guide for humanity until the day of judgment as the inspiration for religious-legal matters; they contain the content and provisions that offer happiness in the two worlds.

In The Mysteries of Purification (Kitab asrar al tahara), the third of the forty books of the Revival of the Religious Sciences (Ihya' 'ulum al-din), Abu Hamid al-Ghazali explains the fundamentals of the purification that is necessary in order to perform the five daily prayers. The book begins with an introduction to the general topic of purity. Al-Ghazali explains the hadith "Purification is half of faith," and reminds readers that, for the earliest Muslims, inner purification was much more important (...) than outer purification. In chapter 1, he considers purification from impurities: What are the impurities and how should they be removed? Over the following chapters, al-Ghazali examines the lesser ablution (wudu), the greater ablution (ghusl), and the "dry ablution" (ablution without water, or tayammum). He discusses the etiquette of the bathhouse and outlines exactly how to clean the body of external things and natural growths; finally, he discusses the beard and practices related to it. (shrink)
