This paper is devoted to the analysis of Plotinus’ citation of the Heraclitean saying B113 DK in the second treatise On the Presence of Being (VI 5 [23]). I shall argue that the use which the author of the Enneads makes of this fragment has been hitherto misunderstood by scholars and that, for this reason, the significance of the passage and its role within Plotinus’ argument have been missed. Close attention will be paid to the tool through which Plotinus conveys (...) his own reading of Heraclitus’ tenet, i.e. etymology, and to the passages in which he both lays down and puts into practice the programmatic guidelines for his interpretation of the Presocratic. In addition, I shall interpret Plotinus’ recourse to a wordplay which is, in character, quite Heraclitean as a proof of the importance of his philosophical engagement with the Obscure. (shrink)

There have been various attempts to apply Darwinian evolutionary theory to an understanding of the human condition within psychology and the social sciences. This paper evaluates whether Darwinian Theory can explain human consciousness. Starting with a brief definition of phenomenal consciousness and the central features of evolutionary theory, the paper examines whether random variations in the genome that confer a selective, reproductive advantage can explain both the emergence of consciousness and its varied forms. To inform the discussion, the paper reviews (...) what is known about the conditions for consciousness within the human mind/brain, understood in both structural (neural) terms and functional terms (in terms of human information processing), and concludes that “random variations in the genome” provide no explanatory mechanism for why some neural activities (but not others) are accompanied by consciousness. The paper then evaluates the many functional advantages that have been proposed for various forms of phenomenal consciousness once they emerge, and concludes that, on close examination, phenomenal experiences themselves do not carry out the information processing functions attributed to them, which challenges the Darwinian requirement that they could only have persisted (once emergent) it they enhanced reproductive fitness. The paper turns finally to what can be said about wider distribution of consciousness in non-humans, contrasting discontinuity theories with continuity theories. Discontinuity theories argue for a critical functional transition that “switches on consciousness” while continuity theories argue for a gradual transition in consciousness from unrecognisable to recognisable. All theories accept that there is an intimate, natural relationship of conscious experiences with their associated material forms. Consequently, as the material forms evolve, their associated experiences co-evolve—suggesting an indirect mechanism by which the emergence of species-specific forms of consciousness can be influenced by Darwinian evolution. It also allows a non-reductive understanding of human consciousness within the social sciences. (shrink)

Background: Positive effects of acute exercise on cognitive performances in general inspired research that investigated the effects of acute exercise on specific cognitive subdomains. Many existing studies examined beneficial effects of acute exercise on subsequent set shifting performance in healthy adults. Set shifting, a subdomain of executive function, is the ability to switch between different cognitive sets. The results of existing studies are inconsistent. Therefore, a meta-analysis was conducted that pooled available effect sizes. Additionally, moderator analyses were carried out to (...) identify covariates that determine the magnitude of exercise-induced set shifting benefits.Methods: Medline, PsycINFO, and SPORTDiscus were searched for eligible studies. Hedges' g corrected standardized mean difference values were used for analyses. Random-effects weights were applied to pool effects. Potential moderation of the effect of acute exercise on subsequent set shifting performance by exercise intensity, type of exercise, participants' age, and type of control group were examined.Results: Twenty-two studies were included into analysis. All aggregated effect sizes ranged from small to moderate. Overall, a small significant beneficial effect was revealed. Heterogeneity of included effect sizes was moderate and significant. Moderator analyses revealed a larger average effect in older adults than for studies examining younger adults. Light exercise led to larger effects than moderate or vigorous exercise. Studies testing acute exercise against active control groups showed a noticeably smaller average effect than studies that used passive or cognitive engaging control groups. Interestingly, application of resistance or aerobic exercise led to no different average effect sizes. However, none of the tested covariates reached statistical significance.Conclusion: Acute exercise improves subsequent set shifting performance. However, effect sizes are small, making the relevance for everyday life questionable. The results indicate that older adults benefit more from acute exercise than younger adults do. Light intensity exercise seems most effective while the type of exercise does not seem to influence the magnitude of effects. Research designs with active control groups show the smallest average effect, raising concerns about placebo effects.PROSPERO registration number: CRD42019138799. (shrink)

Classical logic, intuitionism, relevant logics and many other systems try to express implication as an entailment. The Jaskowski system Qf describes implication in connection with causality. Syntactic properties of Qf have been examined by Pieczkowski [4], [5]. The semantic characterization of Qf is the aim of this paper.

For over a decade, we have watched the state affairs/practitioner constituency within the American Psychological Association move steadily to become the single largest group—clearly a majority—within the membership ranks of the association. Over the same period of time and as the obverse of related demographic phenomena, the research/academic constituency has shrunk to around 30% of the membership. Since power over the affairs of and the destiny of APA has traditionally resided in the hands of the latter, it probably would have (...) been too much to hope that the visionaries in the research/academic community would have made way gracefully for new leadership to be seated in the positions of authority in the association, a leadership more attuned to the needs of APA's majority. So it is not surprising that an orderly transfer of power has not taken place. 2012 APA, all rights reserved). (shrink)

The author points out that in some cases there are two distinct descriptions of the same phenomenon. The first one by means of the theory of chaos, the second - by the theory of causal relationship. The thesis is that these descriptions are not inconsistent but appear at different levels of abstraction.
