While the early Platonic dialogues have often been explored and appreciated for their ethical content, this is the first book devoted solely to the epistemology of Plato's early dialogues. Author Hugh H. Benson argues that the characteristic features of these dialogues--Socrates' method of questions and answers, his fascination with definition, his professions of ignorance, and his thesis that virtue is knowledge--are decidedly epistemological. In this thoughtful study, Benson uncovers the model of knowledge that underlies these distinctively Socratic views. (...) What emerges is unfamiliar, yet closer to a contemporary conception of scientific understanding than ordinary knowledge. (shrink)

I argue against a formidable interpretation of Plato’s Divided Line image according to which dianoetic correctly applies the same method as dialectic. The difference between the dianoetic and dialectic sections of the Line is not methodological, but ontological. I maintain that while this interpretation correctly identifies the mathematical method with dialectic, ( i.e. , the method of philosophy), it incorrectly identifies the mathematical method with dianoetic. Rather, Plato takes dianoetic to be a misapplication of the mathematical method by a subset (...) of practicing mathematicians. Thus, Plato’s critique of dianoetic is a not a critique of mathematics, as such, but of mathematicians. (shrink)

This study of Plato’s hypothetical method is a more than welcome addition to the literature on philosophical method in Plato’s middle dialogues. Benson’s study is remarkable for unusual care and thoroughness in the development of its arguments, and the fairness of its treatment of rival interpretations. One can safely predict that future work on the topic will have to come to grips with his arguments and original interpretations.Benson begins with a careful analysis of the brief descriptions of the (...) method in Meno and Phaedo, then examines its application there and in relevant Republic passages. Benson finds the method a way of conducting what he calls ‘de novo inquiry’ aimed at acquiring knowledge. In Meno the.. (shrink)

Physical activity and sedentary behaviour have been linked to the mental health of children and adolescents, yet the timing of behaviours may play a role in this relationship and clarifying this could inform interventions. We explored cross-sectional associations of PA and SED in varying time segments throughout the school day with the mental health of school-aged children and adolescents from rural Northeastern Ontario, Canada. A total of 161 students wore accelerometers for 8 days and completed a self-report survey. Mental health (...) was measured using the Strengths and Difficulties Questionnaire. Accelerometer-measured SED, light PA, and moderate and vigorous PA were estimated in the time-segments before school, school time, after school, and evenings. Associations were tested with multilevel linear regressions while adjusting for confounding factors. Students spent 72.6 min in MVPA, 209.0 min in LPA, and 621.0 min in SED per day. Daily SED was associated with less conduct problems. Evening LPA was inversely associated with hyperactivity, while SED was associated with hyperactivity and with peer problems before school, and during school. No associations were observed for MVPA, emotional symptoms, or prosocial behaviour. In conclusion, displacing SED with LPA in some specific periods of the day may benefit the mental health of students; taking this into account could strengthen interventions. (shrink)

Hugh H. Benson explores Plato's answer to Clitophon's challenge, the question of how one can acquire the knowledge Socrates argues is essential to human flourishing-knowledge we all seem to lack. Plato suggests two methods by which this knowledge may be gained: the first is learning from those who already have the knowledge one seeks, and the second is discovering the knowledge one seeks on one's own. The book begins with a brief look at some of the Socratic dialogues where (...) Plato appears to recommend the former approach while simultaneously indicating various difficulties in pursuing it. The remainder of the book focuses on Plato's recommendation in some of his most important and central dialogues-the Meno, Phaedo, and Republic-for carrying out the second approach: de novo inquiry. The book turns first to the famous paradox concerning the possibility of such an inquiry and explores Plato's apparent solution. Having defended the possibility of de novo inquiry as a response to Clitophon's challenge, Plato explains the method or procedure by which such inquiry is to be carried out. The book defends the controversial thesis that the method of hypothesis, as described and practiced in the Meno, Phaedo, and Republic, is, when practiced correctly, Plato's recommended method of acquiring on one's own the essential knowledge we lack. The method of hypothesis when practiced correctly is, then, Platonic dialectic, and this is Plato's response to Clitophon's challenge. (shrink)

Sub-Saharan emerging countries experience electrical shortages resulting in power rationing, which ends up hampering economic activities. This paper proposes an approach for very short-term blackout forecast in grid-tied PV systems operating in low reliability weak electric grids of emerging countries. A pilot project was implemented in Arusha-Tanzania; it mainly comprised of a PV-inverter and a lead-acid battery bank connected to the local electricity utility company, Tanzania Electric Supply Company Limited. A very short-term power outage prediction model framework based on a (...) hybrid random forest algorithm was developed using open-source Python machine learning libraries and using a dataset generated from the pilot project’s experimental microgrid. Input data sampled at a 15-minute interval included day of the month, weekday, hour, supply voltage, utility line frequency, and previous days’ blackout profiles. The model was composed of an adaptive similar day module that predicts 15 minutes ahead from a sliding window lookup table spanning 2 weeks prior to the prediction target day, after which ASD prediction was fused with RF prediction, giving a final optimised RF-ASD blackout prediction model. Furthermore, the efficacy analysis of the short-term blackout prediction of the formulated RF, ASD, and RF-ASD regression and classification algorithms was compared. Considering the stochastic nature of blackouts, their performance was found to be fair in short-term blackout predictions of the test site’s weak grid using limited input data from the point of coupling of the user. The models developed were only able to predict blackouts if they occurred frequently and contiguously, but they performed poorly if they were sparse or dispersed. (shrink)

The success of assisted reproductive technologies (ARTs) worldwide has led to an accumulation of frozen embryos that are surplus to the reproductive needs of those for whom they were created. In these situations, couples must decide whether to discard them or donate them for scientific research or for use by other infertile couples. While legislation and regulation may limit the decisions that couples make, their decisions are often shaped by their religious beliefs. Unfortunately, health professionals, scientists and policy-makers are often (...) unaware of the way in which faith traditions view ART and decisions concerning the ‘fate’ of surplus embryos. In this paper scholars representing six major religious traditions provide a commentary on a hypothetical case concerning the donation or destruction of excess ART embryos. These commentaries provide a rich account of religious perspectives on the status of the human embryo and an insight into the relevance of faith to health and policy decisions, particularly in reproductive medicine, ART and embryo research.

After an introductory discussion primarily aimed to differentiate her approach to reading the Platonic dialogues from the so-called argument-focused approach, Gordon argues that Socratic dialectic—which she understands as “the question and answer depicted in the dialogues between Socrates and the interlocutors”—does not simply aim at uncovering inconsistencies in the interlocutors’ belief sets, but at urging through extra-logical means the interlocutors to live a particular—philosophical—kind of life. Next, she argues via a discussion of reader response theory for the parallelism between Socrates’ (...) relationship with his interlocutors and Plato’s relationship with his readers. Thus, Plato, like Socrates, should be seen as urging his readers through extra-logical means to live a particular life—‘to turn toward philosophy’. The remainder of the book consists of four chapters devoted to discussing the extra-logical means by which Plato accomplishes this urging—his use of dramatic effects, his use of character development, his use of irony, and his use of images. While I presume that Gordon would not object to my parenthetical inclusion of ‘logical’ in the description of her argument, it is clear that the focus of her attention in this book is the extra-logical means.

This essay attempts to develop an account of the abilities which free action involves. I argue that the notion of ability which is especially relevant for the purpose of understanding free action is correctly given a compatibilist interpretation. More importantly, it turns out that persons who act freely have the ability to do otherwise than they do. Acting with the ability to do otherwise is not a distinctive mark of free action, however, since anyone who merely acts intentionally possesses that (...) ability. The central idea of this essay emerges as a result of this conclusion: I suggest that we will better understand free action if we abandon the traditional emphasis on free agents' ability to do otherwise and look instead to their ability to criticize courses of action in light of applicable normative standards. ;This suggestion yields two conditions of freedom. The first is that persons act freely only if they competently criticize the courses of action they perform or have control over their failure to do so. The second condition states that persons act freely only if they have control over whether or not they act as they do. They have this control just in case their conduct is counterfactually controllable through certain practical judgments they might arrive at were they to reflect critically on their actions. ;The first condition of freedom is particularly interesting because it shows freedom of action to be a normative notion. The second condition and the accompanying account of control are of especial interest in virture of the challenges which the possibilities of overdetermined action and weak-willed action pose for them. I use the notion of linked counterfactual dependence to address the challenge of overdetermination. The necessarily exceptional character of weak-willed action allows my account to distinguish weakness of will from psychological compulsion. ;I further propose that the two conditions of freedom afford a fruitful characterization of responsibility as liability to one sort of criticism.
