We reconstruct as much as we can the part of al-Fārābī's treatment of modal logic that is missing from the surviving pages of his Long Commentary on the Prior Analytics. We use as a basis the quotations from this work in Ibn Sīnā, Ibn Rushd and Maimonides, together with relevant material from al-Fārābī's other writings. We present a case that al-Fārābī's treatment of the dictum de omni had a decisive effect on the development and presentation of Ibn Sīnā's modal logic. (...) We give further evidence that the Harmonisation of the Opinions of Plato and Aristotle was not written by al-Fārābī. (shrink)

Universal Generalization, if it is not the most poorly understood inference rule in natural deduction, then it is the least well explained or justified. The inference rule is, prima facie, quite ambitious: on the basis of a fact established of one thing, I may infer that the fact holds of every thing in the class to which the one belongs—a class which may contain indefinitely many things. How can such an inference be made with any confidence as to its validity (...) or ability to preserve truth from premise to conclusion? My goal in this paper is to explain how Universal Generalization works in a way that makes sense of its ability to preserve truth. In doing so, I shall review common accounts of Universal Generalization and explain why they are inadequate or are explanatorily unsatisfying. Happily, my account makes no ontological or epistemological presumptions and therefore should be compatible with whichever ontological or epistemological schemes the reader prefers. (shrink)

As part of a review symposium on DARWIN'S ARGUMENT BY ANALOGY: FROM ARTIFICIAL TO NATURAL SELECTION (2021), the journal METASCIENCE invited Roger White, Jon Hodge and me to submit a response to the thoughtful commentaries on our book by Andrea Sullivan-Clarke, David Depew and Andrew Inkpen.

The study determined the chemical composition and acceptability of organic bath soap among students in Yaba College of Technology, Yaba, Lagos State, Nigeria. The study was guided by two research questions. Mixed method research design was used for the study. Population was 46 which comprised all Home Economics students from the Department of Vocational Education. In-home use questionnaire was used for data collection. The study produced two samples of turmeric bath soap. Findings showed that the chemical compositions of the turmeric (...) soap samples are in accordance with the specifications of the Standard Organization of Nigeria (SON) with toilet soap specifications of pH ranging from 9 to 11, total fatty matter ranging from 60-75 gm and total free caustic soda ranging from 0.05 to 0.08 %. Findings showed that the sensory evaluation attributes for colour, smell, consistency foam ability and skin sensitivity were accepted after use for three months as the samples were skin friendly, safe to use without side effects. It was recommended that turmeric body soap and turmeric face gel can be produced in large quantities for commercial purpose as a form of income generation for unemployed graduates. (shrink)

Purpose: This study evaluates staff Training and Development Programmes (TDPs) in secondary schools based on the views of administrators and teachers. The research was implemented in public secondary schools in Cross River State, Nigeria. Design/Methodology/Approach: The study adopted the survey research design with 5408 participants (administrators = 542; teachers = 4595). Four research questions guided the study. The Staff Training and Development Programmes Questionnaire (STDPQ) was used for data collection. Findings revealed essential areas of staff training and development. Findings: Various (...) methods are employed for staff training and development. The results further showed various constraints that impeded staff TDPs in secondary schools. Conclusion: Based on the findings, it was concluded that staff in secondary schools have different training and development needs adjudged by both the principals and teachers as crucial for job enhancement. Various staff training and development methods can serve as valuable programmes to improve the current methods adopted. Research Limitations and Implications: There are various limitations in this study such as the small scope which may affect the extent to which generalizations can be made. It is suggested that future studies focus on expanding the scope to other regions and nations. Practical Implications: Despite the limitations, the study has made some advances to human capital and self-determination theories by providing findings. The findings of this study may direct the attention of curriculum planners, the government and school management to offer training and development opportunities based on the needs of teachers. Contribution to Literature: The study has contributed to the literature on staff training and development which can constitute a basis for further research in related areas. (shrink)

Introduction: Research has documented the prevalence of different HIV/AIDS prevention programs launched to reduce the spread of the virus. However, the extent to which the success or otherwise of these programs are achieved is rarely discussed. This study addresses this gap by analyzing the impact of three socioeconomic parameters on the evaluation of HIV/AIDS prevention programs in the Southern Senatorial District of Cross River State, Nigeria. Methods: A sample of 239 health care employees selected using the proportional stratified random sampling (...) technique participated in the study. A priori power analysis (using G*power) indicated that the sample size was large enough to achieve a 96.7% statistical power. Data was collected using a structured questionnaire. Exploratory factor analysis assessed the dimensionality of the instrument. Acceptable construct and discriminant validity and composite reliability coefficients were obtained. At the .05 alpha level, the null hypotheses were tested using a one-way analysis of variance. Findings: Findings indicated that the evaluation of HIV/AIDS prevention programs significantly varied with the level of funding provided (F[2, 236]=81.11, p<.001), human capacity available (F[2, 236]=40.91, p<.001), and stigmatization to people living with AIDS (F[2, 236]=40.79, p<.001). Health facilities with higher funding and human capacity successfully evaluated HIV/AIDS prevention programs. However, the evaluation of HIV/AIDS prevention programs was lower in areas with a high level of stigmatization. Conclusion and implication: This study’s findings provided evidence that funding, human capacity, and stigmatization affect how HIV/AIDS pandemic can be effectively evaluated. This study implies that additional responsibility is required for public health workers to promote quality service delivery across different health facilities. Keywords:. (shrink)

The Adverse Outcome Pathway (AOP) concept is a knowledge assembly and communication tool to facilitate the transparent translation of mechanistic information into outcomes meaningful to the regulatory assessment of chemicals. The AOP framework and associated knowledgebases (KBs) have received significant attention and use in the regulatory toxicology community. However, it is increasingly apparent that the potential stakeholder community for the AOP concept and AOP KBs is broader than scientists and regulators directly involved in chemical safety assessment. In this paper we (...) identify and describe those stakeholders who currently—or in the future—could benefit from the application of the AOP framework and knowledge to specific problems. We also summarize the challenges faced in implementing pathway-based approaches such as the AOP framework in biological sciences, and provide a series of recommendations to meet critical needs to ensure further progression of the framework as a useful, sustainable and dependable tool supporting assessments of both human health and the environment. Although the AOP concept has the potential to significantly impact the organization and interpretation of biological information in a variety of disciplines/applications, this promise can only be fully realized through the active engagement of, and input from multiple stakeholders, requiring multi-pronged substantive long-term planning and strategies.

There are a bewildering variety of claims connecting Darwin to nineteenth-century philosophy of science—including to Herschel, Whewell, Lyell, German Romanticism, Comte, and others. I argue here that Herschel’s influence on Darwin is undeniable. The form of this influence, however, is often misunderstood. Darwin was not merely taking the concept of “analogy” from Herschel, nor was he combining such an analogy with a consilience as argued for by Whewell. On the contrary, Darwin’s Origin is written in precisely the manner that one (...) would expect were Darwin attempting to model his work on the precepts found in Herschel’s Preliminary Discourse on Natural Science. While Hodge has worked out a careful interpretation of both Darwin and Herschel, drawing similar conclusions, his interpretation misreads Herschel’s use of the vera causa principle and the verification of hypotheses. The new reading that I present here resolves this trouble, combining Hodge’s careful treatment of the structure of the Origin with a more cautious understanding of Herschel’s philosophy of science. This interpretation lets us understand why Darwin laid out the Origin in the way that he did and also why Herschel so strongly disagreed, including in Herschel’s heretofore unanalyzed marginalia in his copy of Darwin’s book.

Anaxarchus accompanied Pyrrho on Alexander the Great’s expedition to India and was known as “the Happy Man” because of his impassivity and contentment. Our sources on his philosophy are limited and largely consist of anecdotes about his interactions with Pyrrho and Alexander, but they allow us to reconstruct a distinctive ethical position. It overlaps with several disparate ethical traditions but is not merely a hodge-podge; it hangs together as a unified whole. Like Pyrrho, he asserts that things are indifferent (...) in value and that realizing this indifference leads to contentment. But this doctrine of indifference is rooted in Democritean atomism. And in his pursuit of pleasure and dismissiveness of conventional standards of what is just, noble, and pious, Anaxarchus is closer to fifth century thinkers such as Aristippus, Antiphon, and Critias.

The expanding moral circle lends coherence to the usual hodge-podge of canonical RCR topics. As it is in a person’s own interest to report falsification, understand fabrication, avoid plagiarism, beware of intuition, and justify one’s decisions, it is useful to begin RCR discussions with the principle that we ought to do what is in our own long-term best interests. As it is in the interest of a person’s research group to articulate their reasons for their conclusions, to write cooperatively, (...) review manuscripts professionally, and report statistics transparently, one can introduce the principle that we ought to keep our promises and contracts. As it is a basic matter of rights to respect human subjects, mentor inclusively, recognize intellectual property, and reveal both conflicts of interests and collaborations with private industry, an RCR instructor can introduce the idea that we ought to respect each individual’s moral rights. Finally, as many animals can feel pain, are subjects of their own lives, and have interests of their own, we must take seriously our role in their welfare as research subjects. In this last step, we expand the circle fully, considering animal experimentation, duties to future generations and the natural environment, and the larger social responsibilities of researchers while adopting a utilitarian principle: We ought to do what will maximize aggregate happiness.

The classification of a state of affairs under a legal category can be considered as a kind of con- densed decision that can be made explicit, analyzed, and assessed us- ing argumentation schemes. In this paper, the controversial conflict of opinions concerning the nature of “marriage” in Obergefell v. Hodges is analyzed pointing out the dialecti- cal strategies used for addressing the interpretive doubts. The dispute about the same-sex couples’ right to marry hides a much deeper disa- greement not only (...) about what mar- riage is, but more importantly about the dialectical rules for defining it.

There are two areas of particular importance in Heathen ethics. One is the growth and maintenance of ethical personal power or 'might and main': the inner strength and drive that is necessary to develop and sustain a good character and reputation, and to achieve worthy deeds during our life. The second is the pursuit of relationships and community life that promote individual, group, and community well-being and effective functionality. Any thoughtful reading of Heathen history, old texts, tales, poems and sagas (...) will show how important these two factors were in ancient Heathen life. This was generally illustrated by showing the painful, cascading disruptions that were caused by failures of, and transgressions against, these ethical values and aspirations. Modern Heathens can benefit from a fuller understanding of ancient Heathen ethical views: both their strengths and their weaknesses, their pros and cons. Only by a thoughtful grasp of these concepts can we make the best use of the elder ways as Heathens living in today’s world. This book offers philosophical discussions of certain Heathen ethical concepts, as well as guidelines for using these concepts to live ethically strong and spiritually healthy lives as modern Heathens. Fulfilled OATHS build Heathen might and main, increasing our personal power. Unpaid SHILD (moral obligation) weakens our might and main; taking responsibility for shild heals personal power. FRITH is a fabric of interwoven might and main, created and shared by many: the roots of relationship and community. LUCK and WYRD can be expressed through flows of might and main, discovered along the complex, hidden paths that lead to Heathen wisdom. Understanding, increasing, maintaining, and sharing ethical might and main is a foundation of Heathen ethics. “In Oaths, Shild, Frith, Luck & Wyrd, Winifred Hodge Rose draws on her extensive scholarship and experience to explore what the lore has to tell us about how the Old Heathens viewed certain ethical questions, and to offer suggestions on how these perspectives can help us deal with the challenges that we face today.” Diana L. Paxson, author of Essential Asatru: A Modern Guide to Norse Paganism. “Oaths, Shild, Frith, Luck & Wyrd provides tools for individual and collective healing, and articulates important questions and challenges that we must consider as we adapt the knowledge and life ways of our ancestors to our contemporary context.” Sara Axtell, Ph.D. (shrink)

George Boole emerged from the British tradition of the “New Analytic”, known for the view that the laws of logic are laws of thought. Logicians in the New Analytic tradition were influenced by the work of Immanuel Kant, and by the German logicians Wilhelm Traugott Krug and Wilhelm Esser, among others. In his 1854 work An Investigation of the Laws of Thought on Which are Founded the Mathematical Theories of Logic and Probabilities, Boole argues that the laws of thought acquire (...) normative force when constrained to mathematical reasoning. Boole’s motivation is, first, to address issues in the foundations of mathematics, including the relationship between arithmetic and algebra, and the study and application of differential equations (Durand-Richard, van Evra, Panteki). Second, Boole intended to derive the laws of logic from the laws of the operation of the human mind, and to show that these laws were valid of algebra and of logic both, when applied to a restricted domain. Boole’s thorough and flexible work in these areas influenced the development of model theory (see Hodges, forthcoming), and has much in common with contemporary inferentialist approaches to logic (found in, e.g., Peregrin and Resnik).

My article concerns constitutional interpretation and substantive due process, issues that played a central role in Obergefell v. Hodges (2015), one of the two same-sex marriage cases. (The other same-sex marriage case was United States v. Windsor (2013).) -/- The late Justice Scalia consistently maintained that the Court “invented” substantive due process and continues to apply this legal “fiction” not because the Constitution supports it but simply because the justices like it. Two theories underlay his cynical conclusion. First is the (...) theory of “Constitutional Textualism”—or just plain “Textualism”—which says that the meaning of the Constitution lies entirely within the “four corners” of the document. Second is the theory of “Originalism,” which says that this meaning was fixed at the time of ratification. (Likewise, the meanings of the amendments were fixed at the time of their ratification.) -/- While Justice Scalia helped to inspire a Textualist/Originalist (and anti-substantive-due-process) movement, his Originalism has received far more attention than his Textualism. Since Judge Robert Bork first introduced Originalism to the general public during his Supreme Court nomination hearings in 1987, this theory has ignited passions on all sides and effectively re-framed the entire debate about how to interpret the Constitution. Constitutional scholars, left and right, now define themselves as either for or against Originalism. Meanwhile, Textualism has merely retreated into the background. -/- Part of the reason for this disparate treatment is that many who reject Originalism still consider themselves to be Textualists. They agree with Justice Scalia (and Judge Bork) that the text is all-important. They disagree, however, that its meaning was fixed for eternity at ratification. Instead, they maintain that either the meaning of the text or applications of this meaning to new cases can change as society changes. -/- In this Article, I bring Textualism out of Originalism’s shadow and into broad daylight. I argue that once we dig just a little deeper into the proposition that all of the meaning in the Constitution inheres in its words, we find that this theory simply cannot work. In order to interpret the nation’s foundational document, we must resort to assumptions that it does not explicitly state. (Indeed, even Textualism itself is a theory that the Constitution does not explicitly endorse.) And the notion that “extra-textual” assumptions necessarily inform our interpretations of the Constitution poses a direct and insurmountable threat to Textualism. -/- The Constitution actually requires each judge, when faced with a case concerning the right to privacy, not merely to consider the text but also to anticipate and evaluate the moral, social, and political consequences of both possible decisions before choosing between them. While this position may initially sound counterintuitive, it turns out to be a much more realistic theory of constitutional interpretation than Textualism (and Originalism). -/- I ultimately conclude that, contrary to Justice Scalia, the Constitution most certainly does protect a right to privacy. For what it’s worth, the Obergefell majority agree with me (and oppose Justice Scalia). I aim to show exactly why they are correct. (shrink)

Morality is often thought of as non-rational or sub-rational. In Moral Notions, first published in 1967, Julius Kovesi argues that the rationality of morality is built into the way we construct moral concepts. In showing this he also resolves the old Humean conundrum of the relation between 'facts' and 'values'. And he puts forward a method of reasoning that might make 'applied ethics' (at present largely a hodge-podge of opinions) into a constructive discipline. Kovesi's general theory of concepts - (...) important in its own right - is indebted to his interpretation of Plato, and his three papers on Plato, first published here, explain this debt. This new edition of Moral Notions also includes a foreward by Philippa Foot, a biography of the author, and a substantial afterword in which the editors, Robert Ewin and Alan Tapper, explain the signficance of Kovesi's work.

Some variants of quantum theory theorize dogmatic "unimodal" states-of-being, and are based on hodge-podge classical-quantum language. They are based on ontic syntax, but pragmatic semantics. This error was termed semantic inconsistency [1]. Measurement seems to be central problem of these theories, and widely discussed in their interpretation. Copenhagen theory deviates from this prescription, which is modeled on experience. A complete quantum experiment is "bimodal". An experimenter creates the system-under-study in initial mode of experiment, and annihilates it in the final. (...) The experimental intervention lies beyond the theory. I theorize most rudimentary bimodal quantum experiments studied by Finkelstein [2], and deduce "bimodal probability density" P=|In><Fin| to represent complete quantum experiments. It resembles core insights of the Copenhagen theory. (shrink)
