Popper famously claimed that he had solved the problem of induction, but few agree. This paper explains what Popper's solution was, and defends it. The problem is posed by Hume's argument that any evidence-transcending belief is unreasonable because (1) induction is invalid and (2) it is only reasonable to believe what you can justify. Popper avoids Hume's shocking conclusion by rejecting (2), while accepting (1). The most common objection is that Popper must smuggle in induction somewhere. But this (...) objection smuggles in precisely the justificationist assumption (2) that Popper, as here undestood, rejects.

Colin Cheyne's ‘paradox of reasonable believing’ poses a problem for both internalist and externalist theories of rationality. Cheyne suggests that externalists will more easily solve it. I argue the opposite.

One recent problem in philosophy of science is, “Ought a methodology be construed, not merely as an instrument of appraisal, but also as a source of advice to the practising scientist?” Imre Lakatos and John Worrall, among others, have answered the question in the negative. Alan Musgrave disagrees. In a section entitled, “Appraisals and Advice,” in [9], Musgrave attempts to give us a deductive argument in support of his claim that methodologies should be construed as giving advice. After briefly (...) explaining the plausibility of the claim, I shall present Musgrave's argument in full, and then examine each of his premises. I will try to show that his attempt to answer the above question in the affirmative raises some interesting questions, and which must be answered if his venture is to succeed. I should add, that if my objections are successful against Musgrave's attempt, it would be a Pyrrhic victory: I am neither an inductivist nor do I think that the answer to the question should be in the negative.

Genes are thought to have evolved from long-lived and multiply-interactive molecules in the early stages of the origins of life. However, at that stage there were no replicators, and the distinction between interactors and replicators did not yet apply. Nevertheless, the process of evolution that proceeded from initial autocatalytic hypercycles to full organisms was a Darwinian process of selection of favourable variants. We distinguish therefore between Neo-Darwinian evolution and the related Weismannian and Central Dogma divisions, on the one hand, and (...) the more generic category of Darwinian evolution on the other. We argue that Hull’s and Dawkins’ replicator/interactor distinction of entities is a sufficient, but not necessary, condition for Darwinian evolution to take place. We conceive the origin of genes as a separation between different types of molecules in a thermodynamic state space, and employ a notion of reproducers. (shrink)

Two books have been particularly influential in contemporary philosophy of science: Karl R. Popper's Logic of Scientific Discovery, and Thomas S. Kuhn's Structure of Scientific Revolutions. Both agree upon the importance of revolutions in science, but differ about the role of criticism in science's revolutionary growth. This volume arose out of a symposium on Kuhn's work, with Popper in the chair, at an international colloquium held in London in 1965. The book begins with Kuhn's statement of his position followed by (...) seven essays offering criticism and analysis, and finally by Kuhn's reply. The book will interest senior undergraduates and graduate students of the philosophy and history of science, as well as professional philosophers, philosophically inclined scientists, and some psychologists and sociologists.

The book's essays represent an important contribution to the contemporary philosophical debate concerning Realism and Rationalism. The author defends in a clear and consistent fashion a fallibilist, realistic, and rationalist position in opposition to the idealistic and relativistic viewpoint characteristic of present postmodern philosophy.

A question as old as the study of rhetoric itself, how we might conceive of the ethical basis of persuasion, is as pressing an issue today as ever. One of the earliest critiques of rhetoric comes from Plato's Phaedrus, in which rhetoric is likened to lust, seduction, domination, and even rape in its stance toward the other. Indeed, rhetorical scholarship has remained in contestation with these depictions of rhetoric as akin to coercion and violence.1 Unable to shake Plato's damning criticisms, (...) Plato has become a perpetual interlocutor and sparring partner in the debate regarding rhetorical ethics, leaving rhetorical scholars, as Michael Dues and Mary Brown claim, "boxing Plato's shadow" in attempts to...

Why do scientists do experiments? What do their experiments reveal? Scientifically, can we decide what to believe? Is evolution a scientific theory? Such apparently simple questions are brilliantly investigated by celebrated philosopher and professor Alan Musgrave in order to interrogate the worldviews we inhabit - and their consequences. Musgrave brings to these questions an expansive historical knowledge, provoking readers to enter the now-discredited belief-systems of earlier ages in order to compare these with their own beliefs. Discursive, entertaining, and provocative, Secular (...) Sermons contains fourteen essays by Musgrave - New Zealand's leading contemporary philosopher - examining the basic assumptions of science, religion, and mathematics. The book is an insightful introduction to the philosophical thought of Aristotle, Bacon, Copernicus, Galileo, Newton, Herschel, Darwin, and Einstein, among others. It puts modern science in a broader historical perspective and offers an entertaining introduction to the philosophical paradigm of Critical Rationalism. (shrink)

John Fox argued that deductivism must be supplemented with ‘epistemic syllogisms’, non-deductive arguments whose vindication is trivial if deductivism is correct. I resist this attempt to surpass deductivism.

In 1985, Alan Musgrave raised a serious objection against the possibility that a constructive empiricist could coherently draw the distinction between observables and unobservables. In his brief response in the same year, Bas van Fraassen claimed that Musgrave’s argument only works within the so-called ‘syntactic view’ of theories, while it loses its force in the context of the ‘semantic view’. But this response was not adequate, or so claimed F. A. Muller, who published two articles in order to extend (...) the epistemology of constructive empiricism. In order to do so, Muller provided a rigorous characterization of observability that requires the use of modal logic. The outcome was a new epistemology for constructive empiricism, which van Fraassen apparently endorsed. As will be shown in this article, however, Muller’s extended epistemology is superfluous. Moreover, and more importantly, Musgrave’s argument seems to be a pseudo-problem. (shrink)

Among various cases that equally admit of evidentialist reasoning, the supposedly evidentialist solution has varying degrees of intuitive attractiveness. I suggest that cooperative reasoning may account for the appeal of apparently evidentialist behavior in the cases in which it is intuitively attractive, while the inapplicability of cooperative reasoning may account for the unattractiveness of evidentialist behaviour in other cases. A collective causal power with respect to agreed outcomes, not evidentialist reasoning, makes cooperation attractive in the Prisoners' Dilemma. And a natural (...) though unwarranted assumption of such a power may account for the intuitive appeal of the one-box response in Newcomb's Problem. (shrink)

Sustainability problems often seem intractable. One reason for this is due to difficulties coordinating actors’ efforts to address socially responsible outcomes. Drawing on theories of bounded ethicality and incorporating work on communicating shared values in coordinating action this paper outlines the lack coordination as a matching issue, one complicated by underlying heterogeneity in actors’ moral values and thus motivation to address socially responsible outcomes. Three factors contribute to this matching problem. First, we argue it is not actors’ simple cognitive (...) awareness, but their moral awareness of social issues that explains why certain actors move to address problems while others do not. In other words, actors may recognize sustainability problems, but are not motivated to solve them as they are not understood as moral problems. Second, we posit that progress requires alignment in issues that some actors find worth addressing whereas others do not, thus explaining how heterogeneity in moral perceptions interrupt coordination towards socially important goals. Finally, we propose that progress is undermined if actors myopically focus on level-specific outcomes in ways that elucidates why institutional responses often fail to address individual outcomes and vice versa. We use the existing literature on the socially important issue of food waste to examine our theoretical contribution and develop a typology that explains conditions that inhibit coordination. Thus, our work proposes a psycho-structural view on matching and coordination toward sustainable outcomes, highlighting how psychological and structural constraints prevent effective coordination in addressing sustainability goals.

Many books explain what is known about the universe. This book investigates what cannot be known. Rather than exploring the amazing facts that science, mathematics, and reason have revealed to us, this work studies what science, mathematics, and reason tell us cannot be revealed. In The Outer Limits of Reason, Noson Yanofsky considers what cannot be predicted, described, or known, and what will never be understood. He discusses the limitations of computers, physics, logic, and our own thought processes. Yanofsky describes (...) simple tasks that would take computers trillions of centuries to complete and other problems that computers can never solve; perfectly formed English sentences that make no sense; different levels of infinity; the bizarre world of the quantum; the relevance of relativity theory; the causes of chaos theory; math problems that cannot be solved by normal means; and statements that are true but cannot be proven. He explains the limitations of our intuitions about the world -- our ideas about space, time, and motion, and the complex relationship between the knower and the known. Moving from the concrete to the abstract, from problems of everyday language to straightforward philosophical questions to the formalities of physics and mathematics, Yanofsky demonstrates a myriad of unsolvable problems and paradoxes. Exploring the various limitations of our knowledge, he shows that many of these limitations have a similar pattern and that by investigating these patterns, we can better understand the structure and limitations of reason itself. Yanofsky even attempts to look beyond the borders of reason to see what, if anything, is out there. (shrink)

Through an analysis of key themes in Heidegger's work, the book challenges the traditional theological appropriation of Heidegger and the usual characterizations of religious thinking in terms of faith or belief in, or experience of, some ultimate reality. Heidegger, it is argued, offers a unique approach to a variety of issues and problems in contemporary religious thought and philosophy of religion that results in understanding religious thinking as a resolute openness to the holiness and meaningfulness of the world.

This paper discusses Wittgenstein's take on the problem of other minds. In opposition to certain widespread views that I collect under the heading of the “No Problem Interpretation,” I argue that Wittgenstein does address some problem of other minds. However, Wittgenstein's problem is not the traditional epistemological problem of other minds; rather, it is more reminiscent of the issue of intersubjectivity as it emerges in the writings of phenomenologists such as Husserl, Merleau-Ponty, and Heidegger. This (...) is one sense in which Wittgenstein's perspective on other minds might be called “phenomenological.” Yet there is another sense as well, in that Wittgenstein's positive views on this issue resemble the views defended by phenomenologists. The key to a proper philosophical grasp of intersubjectivity, on both views, lies in rethinking the mind. If we conceive of minds as essentially embodied we can understand how intersubjectivity is possible. (shrink)

I review a variety of theories that attempt to explain how young infants are able to pass spontaneous false belief tests, and then ask whether any of these approaches can explain the 3-year-olds' failure on standard, elicited FB tests. I argue that some of these approaches fail to provide adequate explanations, and I defend an embodied enactive approach that I think does a better job. The primary reason 3-year-olds fail at the elicited FB tests is not due to language problems, (...) the complexity of the situation, or the number of perspectives involved, but because the saliency of the second-person interaction with the experimenter takes precedence over the third-person task.

In classes that examine entrenched injustices like sexism or racism, students sometimes use “distancing strategies” to dissociate themselves from the injustice being studied. Education researchers argue that distancing is a mechanism through which students, especially students of apparent privilege, deny their complicity in systemic injustice. While I am sympathetic to this analysis, I argue that there is much at stake in student distancing that the current literature fails to recognize. On my view, distancing perpetuates socially sanctioned forms of ignorance and (...) unknowing, through which students misrecognize not only their complicity in injustice, but also the ways that injustice shapes the world, their lives, and their knowledge. Thus, distancing is pedagogically problematic because it prevents students from understanding important social facts, and because it prevents them from engaging with perspectives, analyses, and testimonies that might beneficially challenge their settled views and epistemic habits. To substantiate this new analysis, I draw on recent work on epistemologies of ignorance, especially José Medina’s account of “active ignorance.” In order to respond to student distancing, I argue, it is not sufficient for teachers to make students aware of injustice, or of their potential complicity in it. Beyond this, teachers should cultivate epistemic virtue in the classroom and encourage students to take responsibility for better ways of knowing. The article ends by outlining several classroom practices for beginning this work. (shrink)

Many European planning schools recently celebrated their 50th anniversary: a sign that planning education became a distinct and established discipline in Europe. Simultaneously, political regimes, paradigms, cultures, and economies continue fueling mixed connotations within the planning sector. Additionally, growing wicked problems in built areas emphasize an even greater need for well-trained planners. These challenges span climate crises, wars, authoritarian regimes, socio-political instability, and constantly changing global geopolitics. The increasingly complex demands on planners are highly pertinent for Young Academics (YA). They (...) require political, regulatory, and technical knowledge to navigate the profession. To support them and represent their voices in planning debates, the YA network (YAN) of AESOP was established in 2003. We, the current Coordination Team, use this paper to voice our take on the question of what planning challenges dominate and what can be done to prepare YAs better for the future. Building on plenty discussions within the YAN, literature, and AESOP’s activities at large, we propose: A challenge compilation for the profession, a list of core capacities, and a framework for future education. This shall aid in enabling YAs and educators today to set the foundation for planning sustainable and people-centered settlements tomorrow. (shrink)

Berkeley holds that the essence of sensible objects is percipi. So, sensible objects cannot exist unperceived. Naturally, this has invited questions about the existence of sensible objects when unperceived by finite minds. This is sometimes called the Problem of Continuity. It is frequently said that Berkeley solves the problem by invoking God's ever-present perception to ensure that sensible objects maintain a continuous existence. Problems with this line of response have led some to a phenomenalist interpretation of Berkeley's claim. (...) This paper argues that neither of these are Berkeley's solution since he recognizes no such problem. The paper sketches a new interpretation of sensible objects that obviates the need for a "solution" by avoiding the "problem" in the first place. (shrink)
