There are presently two leading foreign policy decision-making paradigms in vogue. The first is based on the classical or rational model originally posited by von Neumann and Morgenstern to explain microeconomic decisions. The second is based on the cybernetic perspective whose groundwork was laid by Herbert Simon in his early research on bounded rationality. In this paper we introduce a third perspective -- the poliheuristic theory of decision-making -- as an alternative to the rational actor and cybernetic paradigms in international (...) relations. This theory is drawn in large part from research on heuristics done in experimental cognitive psychology. According to the poliheuristic theory, policy makers use poly (many) heuristics while focusing on a very narrow range of options and dimensions when making decisions. Among them, the political dimension is noncompensatory. The paper also delineates the mathematical formulations of the three decision-making models. (shrink)

‘If in this book harsh words are spoken about some of the greatest among the intellectual leaders of mankind, my motive is not, I hope, to belittle them.

_Conjectures and Refutations_ is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.

Farmers of the Peruvian Andesmake use of seed-size variation as a source offlexibility in the production of ``nativecommercial'' farmer varieties of Andeanpotatoes and ulluco. In a case study of easternCuzco, the use of varied sizes of seed tubers isfound to underpin versatile farm strategiessuited to partial commercialization (combinedwith on-farm consumption and the next season'sseed). Use of seed-size variation also providesadaptation to diverse soil-moistureenvironments. The importance and widespread useof seed-size variation among farmers isdemonstrated in the emphasis and consistency oflinguistic expressions about (...) this trait. Smalland small-medium seed is typically sown in thecommunity's ``Hill'' unit of sub-humid,upper-elevation agriculture. Seed tubers ofmedium-size and larger are needed fordrought-stressed locales in lower-elevationlandscape units.

In this essay, I develop and defend a virtue‐theoretic conception of rationality as a capacity whose function is understanding, as opposed to mere truth or correctness. I focus on two main potential advantages of this view. First, its ability to explain the rationality of forms of explanatory reasoning, and second, its ability to offer a more unified account of theoretical and practical rationality.

Realism and the Aim of Science is one of the three volumes of Karl Popper’s Postscript to the Logic of scientific Discovery. The Postscript is the culmination of Popper’s work in the philosophy of physics and a new famous attack on subjectivist approaches to philosophy of science. Realism and the Aim of Science is the first volume of the Postcript . Popper here formulates and explains his non-justificationist theory of knowledge: science aims at true explanatory theories, yet it can (...) never prove, or justify, any theory to be true, not even if is a true theory. Science must continue to question and criticise all its theories, even those that happen to be true. Realism and the Aim of Science presents Popper’s mature statement on scientific knowledge and offers important insights into his thinking on problems of method within science. (shrink)

[A]ny theory of practical rationality must explain— or explain away—the following: Rational: In many cases, what it is rational (in some sense) for one to do or intend to do depends on what one desires. [...] I argue that in order to capture the rational significance of desire, we need to consider both its content and its force, on analogy to the rational significance of both the force and content of beliefs and perceptual experiences. This will open up a new (...) and more elegant way of explaining Rational, while also allowing us to understand how our desires provide us with a basic form of normative experience. Thus, in the end, this will provide the basis for a novel defense of the ancient thesis that desire, in some sense, presents its object under the “guise of the good.”. (shrink)

In the following I discuss the debate between epistemological internalists and externalists from an unfamiliar meta-epistemological perspective. In doing so, I focus on the question of whether rationality is best captured in externalist or internalist terms. Using a conception of epistemic judgments as “doxastic plans,” I characterize one important subspecies of judgments about epistemic rationality—focusing on the distinctive rational/functional role these judgments play in regulating how we form beliefs. Then I show why any judgment that plays this role should be (...) expected to behave the manner internalists predict. In this way, I argue, we can explain why our basic toolbox for epistemic evaluation includes an internalist conception of rationality. (shrink)

Famously, in the second Critique, Kant claims that our consciousness of the moral law provides us with sufficient grounds for the attribution of freedom to ourselves as noumena or things-in-themselves. In this way, while Kant insists that we have no rational basis to make substantive assertions about things-in-themselves from a theoretical point of view, it is rational for us to assert that we are noumenally free from a practical one. This much is uncontroversial. What is controversial is the cognitive relation (...) to things-in-themselves that is possible from a practical point of view. Interpreters have tended to regard such “practical cognition” of things-in-themselves as a poor step-cousin of its theoretical counterpart — as a sort of mere “rational faith” unworthy of comparison with genuine theoretical knowledge or cognition. Recent work on these issues has begun to shift this picture. But this reassessment is in its early stages and remains highly controversial. My aim here is to take this tendency and push it farther than most have generally been willing to go - at least with respect to our practical self-understanding as noumenally free agents. Indeed, I believe that, far from representing an impoverished cousin of theoretical cognition and knowledge, our practical awareness of ourselves as free possesses the central marks of cognition and knowledge in Kant’s sense of these terms, albeit on practical grounds. Thus, it is no surprise that Kant is willing to speak of our consciousness of the moral law as enabling genuine cognition of noumenal freedom. (shrink)

'Never before has there been so many and such dreadful weapons in so many irresponsible hands.' - Karl Popper, from the Preface All Life is Problem Solving is a stimulating and provocative selection of Popper's writings on his main preoccupations during the last twenty-five years of his life.

This book explores the main stages and key concepts in the development of Kant's critical philosophy, from the early 1760s to the 1790s. Karl Ameriks provides a detailed and concise account of the main ways in which the later critical works provide a plausible defense of the conception of humanity's fundamental end that Kant turned to after reading Rousseau in the 1760s. Separate essays are devoted to each of the three Critiques, as well as to earlier notes and lectures (...) and several of Kant's later writings on history and religion. A final section devotes three chapters to post-Kantian developments in German Romanticism, accounts of tragedy up through Nietzsche, and contemporary philosophy. The theme of an elliptical path is shown to be relevant to these writers as well as to many aspects of Kant's own life and work. The topics of the book include fundamental issues in epistemology and metaphysics, with a new defense of the Amerik's 'moderate' interpretation of transcendental idealism. (shrink)

Why do brains have so many connections? The principles exposed by Andy Clark provide answers to questions like this by appealing to the notion that brains distil causal regularities in the sensorium and embody them in models of their world. For example, connections embody the fact that causes have particular consequences. This commentary considers the imperatives for this form of embodiment.

'I want to begin by declaring that I regard scientific knowledge as the most important kind of knowledge we have', writes Sir Karl Popper in the opening essay of this book, which collects his meditations on the real improvements science has wrought in society, in politics and in the arts in the course of the twentieth century. His subjects range from the beginnings of scientific speculation in classical Greece to the destructive effects of twentieth century totalitarianism, from major figures (...) of the Enlightenment such as Kant and Voltaire to the role of science and self-criticism in the arts. The essays offer striking new insights into the mind of one of the greatest twentieth century philosophers. (shrink)

In this paper I offer an argument for a view about the epistemology of peer disagreement, which I call the “Rational Symmetry View”. I argue that this view follows from a natural conception of the epistemology of testimony, together with a basic entitlement to trust our own faculties for belief formation. I then discuss some objections to this view, focusing on its relationship to other well-known views in the literature. The upshot of this discussion is that, if the Rational Symmetry (...) View is correct, much of the action in the epistemology of disagreement relates—not to how one should treat those one regards as an “epistemic peer” in the sense popular in that literature—but rather to who one should treat as such.

I consider sophisticated forms of relativism and their effectiveness at responding to the skeptical argument from moral disagreement. In order to do so, I argue that the relativist must do justice to our intuitions about the depth of moral disagreement, while also explaining why it can be rational to be relatively insensitive to such disagreements. I argue that the relativist can provide an account with these features, at least in some form, but that there remain serious questions about the viability (...) of the resulting account. (shrink)

A 2016 article in the Journal of Consumer Research argues that busyness has become a status symbol. In earlier societies, such as the 19th century Thorstein Veblen describes in his Theory of the Leisure Class, the wealthy conspicuously avoided work. They saw idleness as an ideal. By contrast, contemporary Americans praise being overworked. They see busy individuals as possessing rare and desirable characteristics, such as competence and ambition. -/- To respond philosophically to our new overworked overlords and status icons, we (...) need only return to the 19th century Danish philosopher Søren Kierkegaard. Kierkegaard is known for his philosophical account of boredom, which is often associated with idleness. If busyness is the opposite of idleness, perhaps he can diagnose busyness also. (shrink)

Soren Kierkegaard (1813‐1855) is primarily known as a moral philosopher. This chapter looks at his contributions to ethics, and shows how Kierkegaard's writings can contribute to epistemology, metaphysics, and other areas of contemporary philosophy. In order to contextualize Kierkegaard's contributions to philosophy the chapter briefly surveys some of the ways Kierkegaard is connected to nineteenth‐century philosophers, as well as classical figures like Socrates. It considers Kierkegaard's contributions to moral philosophy in two ways. First, the chapter briefly recounts Kierkegaard's suspicion of (...) Hegelian social ethics as discussed in Fear and Trembling. While Works of Love contains much of Kierkegaard's mature ethical thought, the former text may still serve as an introduction to his approach. Second, the chapter discusses several specific ways Kierkegaard can contribute to contemporary ethics. It also considers future directions for Kierkegaard scholarship and identifies some other areas of philosophy to which Kierkegaard's writings might contribute. (shrink)

Each of us experiences two conflicting attitudes towards time. On the one hand, we all, at least to some degree, look ahead towards the future. On the other hand, we sometimes feel like we ought to live in the present, without this concern about the future. Derek Parfit claims that we would be happier if we lacked our focus on the future: we would not be sad when good things were in the past, we could take life’s pleasures as they (...) come, and we would have fewer reasons to regret aging and death. Given his emphasis on the future as a philosophical problem, Kierkegaard seems especially challenged by Parfit’s claims. I argue that a response to Parfit’s challenges can be found in Kierkegaard’s discourses on the lily of the field and the bird of the air. Though not often read philosophically, these discourses also contribute to Kierkegaard’s philosophy of time. They can provide readers of Kierkegaard with a response to Parfit’s challenges by proffering a way to care for the future while living in the present. To defend this thesis, my first chapter recounts Parfit’s challenges and extant responses by readers of Kierkegaard to them. Chapters Two and Three develop Kierkegaard’s metaphysics of time by working through The Concept of Anxiety and Philosophical Fragments. The former chapter emphasizes Kierkegaard’s focus on the eschatological future while showing how Kierkegaard can contribute to contemporary debates within the philosophy of time. The latter considers Kierkegaard’s Christology and Trinitarian theology by working through Kierkegaard’s understanding of the past event of the incarnation. The fourth and fifth chapters discuss the ethical implications of Kierkegaard’s metaphysics of time through readings of Christian Discourses and Works of Love. Chapter Four contains my account of the attitude towards time Kierkegaard exhorts us to adopt: facing away from the future and towards the work we are called to do in the present. Chapter Five concludes by discussing the implications of this account for the ways we hope for and love our neighbors. (shrink)

Neo-Kantianism is common conceived as a philosophy ‘from above’, excelling in speculative constructions – as opposed to the attitude of patient description which is exemplified by the phenomenological turn ‘to the things themselves’. When we study the work of Emil Lask in its relation to that of Husserl and the phenomenologists, however, and when we examine the influences moving in both directions, then we discover that this idea of a radical opposition is misconceived. Lask himself was influenced especially by Husserl’s (...) Logical Investigations, and Husserl, especially in his later writings, was in some respects closer to Kant than were the Neo-Kantians. The contrast between the two philosophers can be illustrated by looking at their view of the objects of judgment; for Lask, as for Kant, judgment can relate to the thing as such only in an indirect way. The world of judgment is a collection of ‘imitations holding a secondary position’. It is cut apart from the plain world of real things by what Lask calls a ‘chasm of artificiality and imagery’. For Husserl, in contrast, the object of judgment is a ‘Sachverhalt’ or state of affairs, something ontologically ‘positive’ in the sense that it is an entity in its own right and does not point beyond itself in the manner of a mere sign or proxy for something else.

Every theory of modernity must at least presuppose an implicit ontology of the social-historical. Castoriadis is one of the few who makes these presuppositions explicit. Castoriadis’s socio-cultural ontology reveals that the essentially indeterminate nature of the social-historical entails ontological plurality, in the face of which monological or unilinear theories of modernity collapse — leaving us with a fragmented field of tensions. Castoriadis’s exposition of the ontological plurality of the social-historical is one of his most important contributions to social theory — (...) but when he turns his attention to modernity, he immediately polarizes the field. The aim here is to offer some correctives to Castoriadis’s polarized depiction, primarily by teasing out tensions in his work. (shrink)

This article argues that, under likely empirical conditions, sufficientarianism leads not to an easily achievable duty to maintain a social minimum but to the onerous duty of maintaining a social maximum at the sufficiency level. This happens because sufficientarians ask us to give no weight at all to small benefits for people above the sufficiency level if the alternative is to relieve the suffering of people below it. If we apply this judgment in a world where there are rare diseases (...) and hard-to-prevent accidents that cause people to fall below the sufficiency threshold, all of our discretionary spending will have to be devoted to bringing harder and harder cases up to sufficiency. Nothing will be left for anyone to consume above the sufficiency level. (shrink)

The essay provides an account of the development of Reinach’s philosophy of “Sachverhalte” (states of affairs) and on problems in the philosophy of law, leading up to his discovery of the theory of speech acts in 1913. Reinach’s relations to Edmund Husserl and to the Munich phenomenologists are also dealt with.
