Introduction: Physical distancing under the coronavirus disease 2019 pandemic had a significant impact on lifestyles, including exercise routines. In this study, we examined the relationship between mental health and addictive behaviors, such as excessive exercise and the use of image and performance enhancing drugs across 12 sport disciplines.Materials and methods: A large cross-sectional sample of the adult population was surveyed. The mean age was 33.09. The number of male participants was 668. The use of IPEDs was assessed in conjunction with (...) psychometric measures such as the Exercise Addiction Inventory and the Appearance Anxiety Inventory. The participants were grouped into activity group and non-activity group according to the presence or absence of their exercise habits. The results were compared between these groups, as well as across sport disciplines, while taking into account the relationship between different psychological measures and IPEDs consumption.Results: The frequency of IPEDs use was higher among AG than NAG, although AG participants reported less history of addictions than NAG. The logistic regression analysis revealed that scores equal to or above cutoff points, in both the EAI and AAI, predicted the IPEDs use. Regarding the differences across the various sport disciplines, those who were involved in practicing Weight Lifting and Cross Fit were found to be more at risk of excessive exercising and more inclined to use a wide range of IPEDs.Conclusions: Although exercise could help to increase well-being and prevent addictions during the COVID-19 pandemic, our results show that those in the AG are particularly vulnerable to excessive IPEDs use. Sport disciplines associated with higher EAI and AAI scores have also shown a higher tendency to excessive IPEDs use. Furthermore, the factor of having above the cutoff scores in EAI or AAI in each sport could indicate larger IPEDs consumption regardless of the discipline. In light of the current findings, it is necessary to better define the “non-excessive” levels of exercise in various sport disciplines and an adequate intake of IPEDs to ensure the safety and well-being of people during a pandemic.

Hypotheticals, conditionals, and their connecting relation, implication, dramatically changed their meanings during the nineteenth and early part of the twentieth century. Modern logicians ordinarily do not distinguish between the terms hypothetical and conditional. Yet in the late nineteenth century their meanings were quite different, their ties to the implication relation either were unclear, or the implication relation was used exclusively as a logical operator. I will trace the development of implication as an inference operator from these earlier notions into the (...) first third of the twentieth century using as the starting point the ideas primarily of R. Whately and W. Hamilton before discussing the work of the transitional logicians, A. De Morgan and G. Boole on these topics. Then we discuss the relevant views of four prominent but relatively unknown nineteenth century British logicians, W.E. Johnson, J.N. Keynes, E.E.C. Jones, and H. MacColl, as well as those of the more influential logicians, W.S. Jevons and J. Venn, closing with a section on ‘implication as inference’ where we explore some key ideas of B. Russell and sketch the work of D. Hilbert, P. Hertz, and G. Gentzen who together are responsible for the development of the modern ideas related to the subjects of this paper. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.2 (2004) 231-232 [Access article in PDF] Donald R. Kelley. The Descent of Ideas: The History of Intellectual History. Aldershot, England: Ashgate, 2002. Pp. vii + 320. Cloth, $59.50. The field of intellectual history, once known as the history of ideas, intersects with many other historical sub-disciplines, especially the history of philosophy, the history of literature, the history of science, and cultural history. (...) Donald Kelley, a distinguished intellectual historian and editor of The Journal of the History of Ideas, has written a comprehensive history of his field that emphasizes the process by which scholars who studied the history of thought gradually adopted an approach to their subject that resulted in "the descent of ideas" from philosophical abstraction to the "sublunar" realm of human experience and understanding. This intellectual descent, just like the biological descent of man plotted by Darwin in 1871, has not followed a linear course. Displaying remarkable scholarly range and erudition, Kelley guides the reader through a complex and sometimes amorphous history of intellectual history that covers developments in scholarship from ancient times to the present.The most original and distinctive feature of the book is Kelley's emphasis on the importance of eclecticism in the emergence of intellectual history. The book begins with an exposition of the scholarship of the early nineteenth-century Liberal French philosopher and educator Victor Cousin, whose eclectic approach to teaching the history of philosophy was for him not only the best route to attaining true wisdom but also the key to organizing the history of thought. In this way Cousin helped to make intellectual history a distinct branch of historical scholarship, while his contemporaries Abel-François Villemain and François Guizot marked a parallel shift in interest from the history of ideas to the history of literature and the history of civilization. From this starting point Kelley looks back to classical, medieval, and early modern thought, exploring earlier expressions of eclecticism, including that of Diogenes Laertius in the third century CE, as a distinct and often maligned philosophical tradition. An excellent chapter on the "new" or modern eclecticism of the seventeenth and eighteenth centuries, which rejected syncretism as well as skepticism and which found a place for Christian thought, gives new significance to the work of [End Page 231] Jakob Thomasius, his son Christian Thomasius, and J. J. Brucker, whose Critical History of Philosophy (1742-44) established the history of philosophy as a distinct discipline.Kelley devotes considerable space to discussing the intersection between the history of philosophy and intellectual history. The former has long served as the "taproot" of the latter, even after eighteenth-century philosophers, striving to establish philosophy as a rigorous science, rejected a historical approach to attaining wisdom. This development caused a split within the ranks of philosophers between the "purists" in the Kantian tradition and "culturalists" like J. G. Herder who, "following the descent of ideas into the medium of language, strayed off into what came to be known as cultural history" (p. 4). In a chapter devoted to the history of philosophy in modern times, Kelley explores the contributions made by the philosophers Ernst Cassirer, Benedetto Croce, and Arthur Lovejoy to the field of intellectual history.By taking a long historical perspective on the development of his field, Kelley is able to demonstrate that some recent trends in intellectual and literary history have longstanding precedents. Thus he traces the recent "linguistic turn" in historical analysis, which he styles the "linguistic return," back to the Renaissance, and he sees the claims of twentieth-century scholars who emphasize the importance of narrative structures in giving meaning to the past as restatements of ancient literary theory. In his chapter, "The Way of Ideas and the Ways of Words," Kelley shows that the descent of ideas began long before the emergence of intellectual history as a distinct field. As might be expected in a work of historiography, Kelley's methodology in establishing these precedents and continuities in scholarship is in a certain sense traditional. Yet there is little that...

The present paper is an attempt to develop late Professor K. Satchidananda Murty’s quest to articulate Immanent and Transcendent in his philosophical journey from Upanishads to German idealism and Marxism. It is proposed to be achieved by explicating Murty’s understanding of the views of Kant, Hegel, Feuerbach, and Marx on human condition and its transcendence or emancipation. For this purpose, I will discuss consciousness as the ultimate reality being transcendent and immanent in Vedanta as well as in German idealism. The (...) ambition and challenge of the present article is to pursue Murty’s cross-cultural perspective to the extent that the ideas of thinkers of very different traditions, especially culturally and intellectually distinct traditions, are contested on the fullness of thought concerning immanent and transcendent as is evident in comparing Sankara, Kant, and Hegel on consciousness in relation to Buddha and Marx on suffering and alienation. Whereas Murty refers to them, from cross-cultural perspective, with limited end to substantiate his position on the “realm between” derived from Upanishads and Vedanta infused with Buddhism, I wish to present, from the same perspective, some clarifications, annotations, and summations from German idealism and Marxism, which may be useful for expanding Murty’s preliminary acquaintance with them. I wish to argue that though there is antithetical nature of these perspectives, yet the distinctions between immanent and transcendent have been one of the fundamental conceptual linkages under different cultural background.

Athenaeus preserves an intriguing description by the otherwise unknown writerMoschion of a giant grain-ship, the Syracusia, built by Hiero II of Syracuse in thelater third century B.C.1 The account is extremely circumstantial. Besides a fulldescription of the ship's layout, Moschion gives such details as the name of thearchitect , the size of the construction-force , the construction time , details of the launching arrangements devised byArchimedes, and even the procedure for judging crimes committed on board.

I propose that neural cognition is supported by non-neural storage of a 3-D model of local space, used in the planning of movements. Information is stored in wave-like excitations which couple to neurons in the thalamus, with the wave-vectors of excitations representing spatial positions. This hybrid of neural and non-neural cognition may have fitness advantages over any purely neural mechanism -- in information capacity, geometric accuracy, and fast selective retrieval. The wave excitations may be sustained on a Bose-condensed state of (...) some excitation in the brain, by a mechanism like those investigated by Frohlich, Umezawa, Vitiello and others. These states, being frictionless, can store information indefinitely at low energy levels, insulated from thermal noise, so are an ideal substrate for memory. If a Bose-condensed state is a 3-D representation of local reality, it may be the basis of phenomenal consciousness . The resulting theory of consciousness is highly constrained, and agrees well with the main properties of conscious experience. In this account, consciousness arises from a very simple state of matter, rather than from complexity; and it evolved to meet one of the strongest selection pressures on the brain. (shrink)

Martial wrote about himself and his participation in the everyday life of Rome more than any other extant poet of the post-Augustan Principate. More particularly, dozens of his epigrams describe the life of the ordinary client and his treatment by great and often arrogant patrons. Unfortunately for social and literary historians, however, Martial was writing satirical epigrams, not autobiography. Consequently, his poetry cannot be taken at face value as a direct reflection of Roman life. With regard to literary patronage, the (...) difficulties of interpretation have allowed modern scholars to reach diametrically opposed conclusions. One editor and commentator baldly labelled Martial ‘a chronic beggar’ who ‘despite his numerous friends and the many patroni to whom he paid court,…dragged on a hand-to-mouth existence’. In a recent and more detailed study, on the other hand, Martial is portrayed as a man of independent means, who looked to his powerful amici not for financial support so much as for help in publicizing his work and for protection in literary squabbles.

This essay gives a brief overview of Transhumanism and explores a few of its central ideas in the light of Polanyi’s views about embodiment, Marxism, and reality’s hierarchal order, concluding that although Polanyi would likely appreciate the possibilities of cyborgic augmentation that feature in the Transhumanist route to the posthuman, he would utterly repudiate its metaphysics of disembodied intelligence and its underlying technological determinism.

What we perceive is the product of an intrinsic process and not part of external physical reality. This notion is consistent with the philosophical position of transcendental idealism but also agrees with physiological findings on the thalamocortical system. -Frequency rhythms of discharge activity from thalamic and cortical neurons are facilitated by cholinergic arousal and resonate in thalamocortical networks, thereby transiently forming assemblies of coherent oscillations under constraints of sensory input and prefrontal attentional mechanisms. Perception and conscious experience may be based (...) on such assemblies and sensory input to thalamic nuclei plays merely a constraining role in their formation. In schizophrenia, the ability of sensory input to modulate self-organisation of thalamocortical activity may be generally reduced. If during arousal thalamocortical self-organisation is underconstrained by sensory input, then attentional mechanisms alone may determine the content of perception and hallucinations may arise.

Gray takes an information-processing paradigm as his departure point, invoking a comparator as part of the system. He concludes that consciousness is to be found “in” the comparator but is unable to point to how the comparison takes place. Thus, the comparator turns out not to be an entity arising out of brain research per se, but out of the logic of the paradigm. In this way, Gray both reinvents dualism and remains trapped in the language game of his own (...) model – ending up dealing with the unknowable. (shrink)
