In Schmidt's experiments, only properties of actually produced movements systems are measured; in Fitts' experiments, external task parameters are measured too (target size and distance). Thus, the laws contain variables of different natures and cannot be reduced to each other even formally. These difference especially reveals itself in modeling: a model of variability can be simpler if it deals with the performance variables only. On the other hand, modeling Fitts' law, one should take into account not only the (...) human effector system but features of the experimental apparatus as well. These differences have not been sufficiently reflected in Plamondon & Alimi's target article. (shrink)

In their 2008 paper, Persson and Savulescu suggest that for moral bioenhancement (MBE) to be effective at eliminating the danger of ‘ultimate harm’ the intervention would need to be compulsory. This is because those most in need of MBE would be least likely to undergo the intervention voluntarily. By drawing on concepts and theories from epidemiology, this paper will suggest that MBE may not need to be universal and compulsory to be effective at significantly improving the collective moral standing of (...) a human populace and reducing the threat of ultimate harm. It will identify similarities between the mechanisms that allow biological contagions (such as a virus) and behaviours (such as those concerned with ethical and unethical actions) to develop, spread, and be reinforced within a population. It will then go onto suggest that, just as with the epidemiological principle of herd immunity, if enough people underwent MBE to reach a minimum threshold then the incidence and spread of immoral behaviours could be significantly reduced, even in those who have not received MBE.

A collection of critical essays by English and American scholars, including such controversial academic political theorists as Gutmann, Barry and Nussbaum, that raises questions about the current theoretical reassessment of political liberalism.

The ethics of belief involves an inquiry into what beliefs are legitimate to hold, including religious beliefs. Whatever the criteria determined in such an investigation, adopting a belief that does not meet this criterion is seen as illegitimate and it is considered an ethical violation. English mathematician W. K. Clifford (d. 1879) defines “sufficient evidence” as a criterion in his famous essay, “The Ethics of Belief”. Clifford’s evidence-centered argument becomes one of the most frequent references in the evidentialist objection against (...) theism. It turns out that this argument is not functional in the face of the diversity of beliefs. In this context, different suggestions are presented about what the ethics of belief could be. American philosopher William James (d. 1810), one of the founding names of pragmatism, offers a new proposal. In his classic work, “The Will to Believe”, James claims that Clifford is wrong in seeking the requirement of evidence for all beliefs. Because it is not possible to prove beliefs from the passionate nature of human beings, especially religious beliefs. Following this distinction, James proposes a new criterion for religious beliefs: a religious belief can be vivid or dead, forced or avoidable; and momentous or trivial. If a religious belief is vivid, forced, and momentous, it is necessary to have the courage to believe in it instead of suspending it. James' proposal is often valued as a strong counter-challenge or defense of religious beliefs. However, this argument also has aspects that are open to criticism. One of them is that the will to believe argument concurrently accepts conflicting religious beliefs or, in other words, confronts the issue of religious diversity. According to J. Hick, for example, this argument inevitably results in religious pluralism, even though James does not want to. Contrary to Hick, S. F. Aikin claims that the will to believe does not result in religious pluralism. According to Aikin, who draws attention to the relationship of argument with pragmatism, James obscures religious beliefs and removes them from being claims about truth. Therefore, there is no contradiction in the classical sense. So, which of the objections is valid? Does the will-to-believe argument result in religious pluralism by legitimizing more than one religious belief at the same time, or does it make a purely pragmatic proposition by devaluing religious beliefs? Which religion do I have the right to believe in according to the will to believe? The aim of this article is to provide an answer to the mentioned question. In the article, unlike the current evaluations, it is argued that the argument is closely related to James's theory of knowledge, radical empiricism, not pragmatism as it is usually made. For this purpose, after showing the relationship between the arguments of Clifford and James, the argument will be re-examined in this context and it will be revealed that James has two steps regarding religious beliefs: to make religious beliefs independent from factual beliefs; leaving theism to accept a monistic vision of God and basing religion on mystical experience, which is an emotional experience. As details emerge, it will become clear that James defends a natural religion that excludes traditional religions in his philosophical system and that he defends the beliefs of a humanized religion. With an individual definition of religion based on emotion, James on the one hand ensures the commonality of religious feeling, on the other hand, he makes religion independent from the field of facts. Therefore, with this study, it will be seen that the argument of the will to believe does not aim to legitimize believing in traditional religions, and diversity is not a fundamental problem.

Thomas Hill Green was one of the most influential English thinkers of his time, and he made significant contributions to the development of political liberalism. Much of his career was spent at Balliol College, Oxford: having begun as a student of Jowett, he later acted effectively as his second-in-command at the college. Interested for his whole career in social questions, Green supported the temperance movement, the extension of the franchise, and the admission of women to university education. He became Whyte's (...) professor of moral philosophy at Oxford in 1878, and his lectures had a lasting influence on a generation of students. Much of Volume 1, edited by Green's pupil R. L. Nettleship and published in 1885, consists of Green's work on David Hume . In his essay, 'Introductions to Hume's Treatise of Human Nature' , Green gives a detailed critique of Hume's metaphysical thought. (shrink)

Chalmers (2018) maintains that even if we understood every physical process in the brain we could still wonder why these processes give rise to conscious experience. The meta-problem is the challenge of explaining why we think this 'hard problem' exists. This response to the target paper endorses illusionist accounts of three 'problem intuitions' about consciousness: duality, presentation, and revelation. Subject–object duality is explained in terms of a clash between two compelling but contradictory convictions about consciousness. Phenomenal presence is understood in (...) relation to the configurational features of sensory experiences. And intuitions of revelation are explained as due to an unfounded belief in introspective ontological access. These illusionist analyses are used to bolster the case for physicalist realism rather than to support 'strong' illusionism. In addition to addressing the meta-problem they suggest a promising approach to the hard problem as wel. (shrink)

This target article presents a critical survey of the scientific literature dealing with the speed/accuracy trade-offs in rapid-aimed movements. It highlights the numerous mathematical and theoretical interpretations that have been proposed in recent decades. Although the variety of points of view reflects the richness of the field and the high degree of interest that such basic phenomena attract in the understanding of human movements, it calls into question the ability of many models to explain the basic observations consistently reported in (...) the field. This target article summarizes the kinematic theory of rapid human movements, proposed recently by R. Plamondon (1993b; 1993c; 1995a; 1995b), and analyzes its predictions in the context of speed/accuracy trade-offs. Data from human movement literature are reanalyzed and reinterpreted in the context of the new theory. It is shown that the various aspects of speed/accuracy trade-offs can be taken into account by considering the asymptotic behavior of a large number of coupled linear systems, from which a delta-lognormal law can be derived to describe the velocity profile of an end-effector driven by a neuromuscular synergy. This law not only describes velocity profiles almost perfectly, it also predicts the kinematic properties of simple rapid movements and provides a consistent framework for the analysis of different types of speed/accuracy trade-offs using a quadratic (or power) law that emerges from the model.
