The call for papers for this conference claims that 'the founders of modern philosophy of science, including Sir Karl Popper… saw it as part of their role to explain the authority of science’. It continues by declaring that 'A key motive for Popper's "demarcation criterion" distinguishing science from "pseudo-science" was to restrict the authority of science to disciplines which used the scientific method.' However, a closer look at Popper’s writing shows that this widespread view is incorrect. In fact, Popper declares (...) in the postscript to the Logic of Scientific Discovery: [I]t is all guesswork, doxa rather than epistēmē… Science has no authority… It represents… our hope of emancipating ourselves from ignorance and narrow-mindedness, from fear and superstition. And this includes… the superstitious belief in the authority of science itself. After briefly defending my contention, with reference to the work of Bartley and some of Popper's statements elsewhere, I will argue that Popper is better understood as attempting to demarcate inquiry from non-inquiry. I also hope to show that this humbler goal is worthwhile, especially when it comes to resisting calls to teach so-called ‘creation science’ in schools. Unfortunately, Popper has become associated with the relatively simplistic view that falsifiability is a demarcation criterion. But Popper recognized, even in the first edition of Logic of Scientific Discovery, that falsifiability alone does not suffice. He was cognisant of the problem posed by Duhem's thesis, and therefore stated: A system such as classical mechanics may be ‘scientific’ to any degree you like; but those who uphold it dogmatically—believing, perhaps, that it is their business to defend such a successful system against criticism as long as it is not conclusively disproved—are adopting the very reverse of that critical attitude which in my view is the proper one for the scientist. This would appear to be why Popper wrote of 'the non-existence of scientific method' above and beyond 'the one method of all rational discussion, and therefore of the natural sciences as well as of philosophy… stating one's problem clearly and examining its various proposed solutions critically'. In short, the critical approach is a crucial part of the demarcation puzzle. In the remainder of the talk, I will develop this solution to the demarcation problem in response to several possible criticisms. Chief among these is that 'creation scientists' do inquire but only with narrow scope. To address this criticism, I will draw on some of my recent work on the roles of criticism and dogmatism in science ; and in particular, I will consider if looking at matters from the group level can help.

In his review of Phillip Grier’s anthology, Dialectic and Contemporary Science, Darrel Christensen expresses his regret that I “did not find occasion… to give more attention… to the sorts of well-informed and pointed criticism that E. McMullin raised.. in ‘Is the Progress of Science Dialectical?’” In that book it would hardly have been possible or appropriate, for me to have done so, because I did not write it, and although the editor invited me to respond to the authors who contributed, (...) Ernan McMullin was not one of them. The paper to which Christensen refers was presented to the first meeting of the Hegel Society of America in 1970, at which I was present; but after so long an interval of time I cannot now remember if or how, I responded to it. So far as my recollection serves, my own paper, although distributed to those attending the meeting, was not read and was not fully discussed. So there may well be some need for taking up Christensen’s challenge, even at this late hour. (shrink)

_Popper’s Critical Rationalism_ presents Popper’s views on science, knowledge, and inquiry, and examines the significance and tenability of these in light of recent developments in philosophy of science, philosophy of probability, and epistemology. It develops a fresh and novel philosophical position on science, which employs key insights from Popper while rejecting other elements of his philosophy. Central theses include: Crucial questions about scientific method arise at the level of the group, rather than that of the individual. Although criticism is vital (...) for science, dogmatism is important too. Belief in scientific theories is permissible even in the absence of evidence in their favour. The aim of science is to eliminate false theories. Critical rationalism can be understood as a form of virtue epistemology. (shrink)

When do we agree? The answer might once have seemed simple and obvious; we agree that p when we each believe that p. But from a formal epistemological perspective, where degrees of belief are more fundamental than beliefs, this answer is unsatisfactory. On the one hand, there is reason to suppose that it is false; degrees of belief about p might differ when beliefs simpliciter on p do not. On the other hand, even if it is true, it is too (...) vague; for what it is to believe simpliciter ought to be explained in terms of degrees of belief. This paper presents several possible notions of agreement, and corresponding notions of disagreement. It indicates how the findings are fruitful for the epistemology of disagreement, with special reference to the notion of epistemic peerhood. (shrink)

Can scientific evidence outstretch what scientists have mentally entertained, or could ever entertain? This article focuses on the plausibility and consequences of an affirmative answer in a special case. Specifically, it discusses how we may treat automated scientific data-gathering systems—especially AI systems used to make predictions or to generate novel theories—from the point of view of confirmation theory. It uses AlphaFold2 as a case study.

A discussion on antiquity with Anthony A. Long, one of the most distinguished scholars in the field of ancient philosophy, would be engaging in any case. All the more so, since his two recently published works, Greek Models of Mind and Self and How to be Free: An Ancient Guide to the Stoic Life, provide the opportunity to revisit key issues of ancient philosophy. The former is a lively and challenging work that starts with the Homeric notions of selfhood, (...) and leads the reader all the way through classical and Hellenistic philosophical psychology; the latter is a profound analysis of the Stoic ethics that focuses in particular on its foundation and principles, followed by Long’s re-worked translation of Epictetus’ Encheiridion and carefully selected parts of his Discourses. Anthony Long kindly accepted the invitation to discuss several issues that are in the core of scholarly concern, sharing interpretations and thoughts that originate from his long acquaintance with the ancient literary tradition.

Nell’ambito della filosofia della scienza, il dibattito tra realismo scientifico e antirealismo scientifico ricopre un ruolo di straordinaria importanza. In questo ambito, le posizioni filosofiche elaborate non sono poche. The Instrument of Science di Darrell P. Rowbottom presenta e difende una nuova variante della celebre posizione nota come strumentalismo, di chiaro orientamento antirealista. Questa nuova proposta viene denominata strumentalismo cognitivo (cognitive instrumentalism). Nello specifico, gli obbiettivi dell’autore sono due: definire in modo preciso lo strumentalismo cognitivo, chiarendone le tesi costituenti, (...) e mostrare che questa visione è almeno tanto plausibile quanto lo sono le più accreditate teorie realiste della scienza.

In Medicine, Society, and Faith in the Ancient and Medieval Worlds Darrel Amundsen explores the disputed boundaries of medicine and Christianity by focusing on the principle of the sanctity of human life, including the duty to treat or attempt to sustain the life of the ill. As he examines his themes and moves from text to context, Amundsen clarifies a number of Christian principles in relation to bioethical issues that are hotly debated today. In his examination of the moral stance (...) of the earliest syphilographers, for example, he finds insights into the ethical issues surrounding the treatment of AIDS, which he believes has its closest historical antecedent not in plague but in syphilis. He also shows that the belief that all healing comes from God, whether directly, through prayer, or through the use of medicine -- a sentiment commonly held by contemporary Christians -- cannot be accurately attributed to any extant source from the patristic period. Indeed, all the Church Fathers were convinced that healing sometimes came from evil sources: Satan and his demons were able to heal, for example, and Asclepius was a demon "to be taken very seriously indeed.".

Roughly, instrumentalism is the view that science is primarily, and should primarily be, an instrument for furthering our practical ends. It has fallen out of favour because historically influential variants of the view, such as logical positivism, suffered from serious defects. -/- In this book, however, Darrell P. Rowbottom develops a new form of instrumentalism, which is more sophisticated and resilient than its predecessors. This position—‘cognitive instrumentalism’—involves three core theses. First, science makes theoretical progress primarily when it furnishes us (...) with more predictive power or understanding concerning observable things. Second, scientific discourse concerning unobservable things should only be taken literally in so far as it involves observable properties or analogies with observable things. Third, scientific claims about unobservable things are probably neither approximately true nor liable to change in such a way as to increase in truthlikeness. -/- There are examples from science throughout the book, and Rowbottom demonstrates at length how cognitive instrumentalism fits with the development of late nineteenth- and early twentieth-century chemistry and physics, and especially atomic theory. Drawing upon this history, Rowbottom also argues that there is a kind of understanding, empirical understanding, which we can achieve without having true, or even approximately true, representations of unobservable things. In closing the book, he sets forth his view on how the distinction between the observable and unobservable may be drawn, and compares cognitive instrumentalism with key contemporary alternatives such as structural realism, constructive empiricism, and semirealism. -/- Overall, this book offers a strong defence of instrumentalism that will be of interest to scholars and students working on the debate about realism in philosophy of science.

The purpose of this exploratory action research study was to examine how the modeling by a collaborative team of instructors regarding technology integration and information literacy would affect the quality of the lessons that elementary teacher-education students designed and taught in their field placements. The research was conducted over two distinct years with two different cohorts of methods students placed at a local elementary school that had received new interactive whiteboards, SMART boards, in every classroom at the beginning of the (...) previous school year. Based upon field-supervisor/instructor observations, reflections, and oral and written feedback from host-teachers and students, an analysis was conducted to determine the effectiveness of the interventions. Findings suggest that teacher education students' level of engagement increased regarding the integration of technology, information literacy, ethical information use, and children were more engaged and actively involved during the teaching of methods students' mathematics and science lessons.

When a doctor tells you there’s a one percent chance that an operation will result in your death, or a scientist claims that his theory is probably true, what exactly does that mean? Understanding probability is clearly very important, if we are to make good theoretical and practical choices. In this engaging and highly accessible introduction to the philosophy of probability, Darrell Rowbottom takes the reader on a journey through all the major interpretations of probability, with reference to real–world (...) situations. In lucid prose, he explores the many fallacies of probabilistic reasoning, such as the ‘gambler’s fallacy’ and the ‘inverse fallacy’, and shows how we can avoid falling into these traps by using the interpretations presented. He also illustrates the relevance of the interpretation of probability across disciplinary boundaries, by examining which interpretations of probability are appropriate in diverse areas such as quantum mechanics, game theory, and genetics. Using entertaining dialogues to draw out the key issues at stake, this unique book will appeal to students and scholars across philosophy, the social sciences, and the natural sciences. (shrink)

"A climate crisis and other pressures on planetary ecology are causing profound anxieties. Climate change threatens to trap hundreds of millions of people in dire poverty and to separate further an already deeply divided world. However, a new generation of activists is offering inspiration, serving as a hope-maker. This book offers an accessible and empirically informed philosophical discussion of climate change, global poverty, justice, and the importance of political responses, both internationally and domestically, that offer hope. There are reasons enough (...) to worry that the era of pervasive human planetary impact, the Anthropocene, could produce terrible global injustices and massive environmental destruction. But that need not be so. Since the Industrial Revolution growth in productive capacity and the egalitarian struggles to share its benefits widely have made another world possible. We still have reason to hope for a world in which international cooperation to manage Earth systems sustainably prevails, in which the natural treasures of the Earth are valued, in which a vision of prosperity is realized and the scourges of disease, ignorance, and poverty are overcome, in which powerful lobbies defending private interests that threaten sustainability are minimized and contained, and in which democratic politics responding to the values of an educated public prevail. The work of bringing about such a world is the work of mobilizing hope"--. (shrink)

Though others have surveyed the different methods in comparative religious ethics, relatively little attention has been given to different approaches to pedagogy. The field of comparative religious ethics has now reached a level of maturity so that there are a variety of ways such courses can be taught. In this review I consider the approaches to comparative religious ethics found in four recent texts by Jacob Neusner, Darrell Fasching and Dell deChant, Regina Wolfe and Christine Gudorf, and Sumner Twiss (...) and Bruce Grelle. In the essay I note the strengths and weaknesses of each text, with special attention given to how the texts might work in the classroom. I then argue that the different texts reflect different understandings of the goal of teaching comparative religious ethics, and I make these goals explicit in order to help teachers decide how they might approach the teaching in this growing field.

Responsibility is often thought of as primarily a legal concept. Even when it is moral responsibility that is at issue, it is assumed that it is above all in moralities based on law-centered patterns and models that responsibility takes center stage, so that responsibility is a legal concept at its core, and is applicable to the realm of private morality only by extension and analogy.

Libertarianism needs a theory of class. This claim may meet with resistance among some libertarians. A few will say: “The analysis of society in terms of classes and class struggles is a specifically Marxist approach, resting on assumptions that libertarians reject. Why should we care about class?” A greater number will say: “We recognize that class theory is important, but libertarianism doesn't need such a theory, because it already has a perfectly good one.”.

J. S. Mill's distinction between higher and lower pleasures is often thought to conflict with his commitment to psychological and ethical hedonism: if the superiority of higher pleasures is quantitative, then the higher/lower distinction is superfluous and Mill contradicts himself; if the superiority of higher pleasures is not quantitative, then Mill's hedonism is compromised.

We began with three propositions: that people have a right not to be treated as mere means to the ends of others, that a woman who voluntarily becomes pregnant nevertheless has the right to an abortion, and that a woman who voluntarily gives birth does not have a right to abandon her child until she finds a substitute caretaker. These propositions initially seemed inconsistent, for the prohibition on treating others as mere means appeared to rule out the possibility of positive (...) rights, thus making it impossible to countenance the right to abort or the right not to be abandoned . But we have seen that the prohibition on treating people as mere means to the ends of others is best understood as ruling out basic positive rights while permitting derivative ones. Since a willing mother is responsible for bringing her child into the world in the first place, she cannot abandon it without violating its negative right not to be killed, and so such a child has a derivative positive right not to be abandoned. A pregnant woman, on the other hand, has a negative right not to have her body invaded, and from this negative right derives a positive right to abort her fetus, so long as doing so is not disproportionate to the seriousness of the threat . Therefore, far from being in conflict, propositions , , and have been shown to be in harmony with one another, the latter two being plausibly grounded in the first. Insofar as we have reason to accept , then, we have reason to accept and . Moreover, we have seen that a proper understanding of allows us to embed and in a larger moral perspective in which the limits of compulsory altruism are firmly drawn: enforceable rights to the use or assistance of others may be allowed into the moral domain only if they are “sponsored” by some negative right. Every putative positive right must find such a sponsor, or perish. (shrink)

I answer Alvin Plantinga's challenge to provide a ‘proper’ de jure objection to religious belief. What I call the ‘sophisticates’ evidential objection' concludes that sophisticated Christians lack epistemic justification for believing central Christian propositions. The SEO utilizes a theory of epistemic justification in the spirit of the evidentialism of Richard Feldman and Earl Conee. I defend philosophical interest in the SEO against objections from Reformed epistemology, by addressing Plantinga's criteria for a proper de jure objection, his anti-evidentialist arguments, and the (...) relevance of ‘impulsional evidence’. I argue that no result from Plantinga-style Reformed epistemology precludes the reasons I offer in favour of giving the SEO its due philosophical attention. (shrink)
