Much philosophical progress has been made in elucidating the idea of evolutionary contingency in a recent re-burgeoning of the debate. However, additional progress has been impaired on three fronts. The first relates to its characterisation: the under-specification of various contingency claims has made it difficult to conceptually pinpoint the scope to which ‘contingency’ allegedly extends, as well as which biological forms are in contention. That is—there appears to be no systematic means with which to fully specify contingency claims which has (...) led to a tendency for authors to talk past each other. Secondly, on the matter of evidence, recent research has focused on the evidential import of convergent evolution which is taken to disconfirm the evolutionary contingency thesis. However, there has been a neglect of convergent evolution’s converse: ‘evolutionary idiosyncrasies’ or the singular evolution of certain forms, which I argue is evidentially supportive of evolutionary contingency. Thirdly, evolutionary contingency has often been claimed to vary in degrees and that the debate, itself, is a matter of ‘relative significance’. However, there has been no formal method of evaluating the strength of contingency and its relative significance in a particular domain. In this paper, I address all three issues by proposing a systematic means of fully specifying contingency theses with the concept of the modal range. Secondly, I propose an account of evolutionary idiosyncrasies, investigate the explanations for their occurrences, and, subsequently, spell out their significance with respect to the evolutionary contingency thesis. Finally, having been equipped with the evidential counterpart to convergent evolution, I shall sketch a likelihood framework for evaluating, precisely on the basis of a sequence of opposing data, the strength and relative significance of evolutionary contingency in a particular domain. With this in hand, the relative observations of idiosyncrasies and convergences can be informative of the strength and relative significance of contingency in any particular domain. (shrink)

Paternalist policies in public health often aim to improve people’s well-being by reducing their options, regulating smoking offering a prime example. The well-being challenge is to show that people really are better off for having their options reduced. The distribution challenge is to show how the policies are justified since they produce losers as well as winners. If we start from these challenges, we can understand the importance of the empirical evidence that a very high proportion of smokers regret smoking. (...) In short, it is important that they regret it and important that the proportion is so high. This paper explains how, philosophically, regret can relate to well-being and it considers some of the strengths and weakness in the empirical research that the explanation brings out. The regret case for regulating smoking is indeed strong, although not as strong as the empirical researchers think. It is much weaker for paternalistic intervention in other public health problems, such as obesity and binge drinking. (shrink)

Multiple Sclerosis is a debilitating chronic autoimmune disease of the central nervous system that results in lower quality of life. Medication adherence is important for reducing relapse, disease progression, and MS-related symptoms, particularly during the early stages of MS. However, adherence may be impacted by negative emotional states. Therefore, it is important to identify protective factors. Past research suggests that the ability to discriminate between negative emotional states, also known as negative emotion differentiation, may be protective against enactment of maladaptive (...) risk-related behaviors. However, less is known as to how NED may promote adaptive health behaviors such as medication adherence. Utilizing weekly diaries, we investigated whether NED moderates the association between negative affect and medication adherence rates across 58 weeks among patients newly diagnosed with MS. Results revealed that NED significantly moderated the relationship between negative affect and medication adherence. Specifically, greater negative affect was associated with lower adherence only for individuals reporting low NED. However, this link disappeared for those reporting moderate to high NED. Building upon past research, our findings suggest that NED may promote adaptive health behaviors and have important clinical implications for the treatment and management of chronic illness.

In his investigation of the concept of "Being", Aristotle relates the question of "existence" to the question "essence" and considers essence as "whatness" and quiddity. Although in his logical discussions he treats the concepts of "existence" and "whatness" separately and makes a distinction between them, but does not extend this distinction to the area of philosophical topics. But in the prepatetic Islamic system of Philosophy, explanation and distinction between "Being" and "quidity" is without doubt one of the most fundamental philosophical (...) doctrines and beliefs. In the history of Islamic philosophy, the theory of metaphysical distinction between being and essence has been attributed to Ibn Sina, but it is Farabi who for the first time has propounded clearly and decisively a two – part division between "being" and "quiddity" and has prepared the way for Avecinian philosophy. In addition to his logical distinction between "existence" and "whatness" of things he has stressed on a metaphysical distinction between them and has made this distinction the foundation of his metaphysical system. From Farabi's view, being is an inherent accident of quiddity. In this article we try to explain the concepts of "existence" and "whatness" of things and their relation as one of the most fundamental topics in prepatetic philosophy in the philosophical thought of these two great prepatetic philosophers, ie Aristotle and Farabi, with specific stress on comparing their views.

Governments can try to counter obesity through preventive regulations such as sugar taxes, which appear to raise costs or reduce options for consumers. Would the regulations improve the welfare of adult consumers? The regulations might improve choice sets through a mechanism such as reformulation, but the scope for such improvement is limited. Otherwise, a paternalistic argument must be made that preventive regulations would improve welfare despite reducing choice. This paper connects arguments about obesity, health, and choice to a philosophically plausible (...) view of welfare. On the negative side, two errors to avoid are failing to see the limited value of health and thinking that findings of irrationality would alone settle arguments about welfare. On the positive side, preventive regulations could make people better-off if welfare is the satisfaction of preferences and if preventive regulations could better satisfy preferences by overcoming certain forms of irrationality. The leading evidence is from widespread attempts to lose weight. However, at least for the United States, most adults are not trying to lose weight, and that casts doubt on whether they would benefit from preventive regulations. If they would not, that seems a strong albeit not decisive reason against these regulations. (shrink)

We group encephalitic behaviors as shown in Table 1. It is striking that the majority of these behaviors, namely groups 1 and 2, help spread viral and bacterial infections underlying encephalitis, a situation similar to Ophiocordyceps unilateralis .Could some of the behaviors in Table 1 be of utility to the host as well? Note that the behavioral symptoms may not coincide with impaired intellect . Furthermore, these symptoms may be vestigial in the sense of having been of utility to the (...) host species at a time when the latter possessed lower intelligence to begin with. It is also important to note that encephalitis is often triggered by physical and emotional stress, so that utility of behaviors is better assessed for such conditions.Continuous and compulsive exploration of one’s environment is of course a recipe for learning and discovery.

An important contribution to the foundations of probability theory, statistics and statistical physics has been made by E. T. Jaynes. The recent publication of his collected works provides an appropriate opportunity to attempt an assessment of this contribution.
