Many idealists have thought that realism raises epistemological problems. The worry is that, if it is possible for truths about ordinary objects to outstrip our experiences in the ways that realists typically suppose, we could never be justified in our beliefs about objects. Few contemporary theorists find this argument convincing; philosophers have offered a variety of responses to defend the epistemology of our object judgments under the assumption of realism. But in this paper, I offer a new type of epistemic (...) argument against realism which is immune to the standard responses in the literature. In addition to raising a challenge for realism, the epistemology of our object judgments has implications for how the idealist should develop her own positive metaphysical view. So in the second half of this paper, I discuss how the idealist should understand the dependence between objects and our experiences if she is to secure epistemic advantages over the realist.

¿The fox knows many things, but the hedgehog knows one big thing.¿ This fragment of Archilochus, which gives this book its title, describes the central thesis of Isaiah Berlin¿s masterly essay on Tolstoy. There have been various interpretations of Archilochus¿ fragment; Isaiah Berlin has simply used it, without implying anything about the true meaning of the words, to outline a fundamental distinction that exists in mankind, between those who are fascinated by the infinite variety of things (foxes) and (...) those who relate everything to a central all-embracing system (hedgehogs). When applied to Tolstoy, the image illuminates a paradox of his philosophy of history, and shows why he was frequently misunderstood by his contemporaries and critics. Tolstoy was by nature a fox, but he believed in being a hedgehog. (shrink)

‘IB was one of the great affirmers of our time.’ John Banville, New York Review of Books The title of this final volume of Isaiah Berlin’s letters is echoed by John Banville’s verdict in his review of its predecessor, Building: Letters 1960–75, which saw Berlin publish some of his most important work, and create, in Oxford’s Wolfson College, an institutional and architectural legacy. In the period covered by this new volume (1975–97) he consolidates his intellectual legacy with a series (...) of essay collections. These generate many requests for clarification from his readers, and stimulate him to reaffirm and sometimes refine his ideas, throwing substantive new light on his thought as he grapples with human issues of enduring importance. Berlin’s comments on world affairs, especially the continuing conflict between Israel and the Palestinians, and the collapse of Communism, are characteristically acute. This is also the era of the Northern Ireland Troubles, the Iranian revolution, the rise of Solidarity in Poland, the Chernobyl nuclear disaster, the fall of the Berlin Wall, Ayatollah Khomeini’s fatwa against Salman Rushdie, the spread of Islamic fundamentalism, and wars in the Falkland Islands, the Persian Gulf and the Balkans. Berlin scrutinises the leading politicians of the day, including Reagan, Thatcher and Gorbachev, and draws illuminating sketches of public figures, notably contrasting the personas of Alexander Solzhenitsyn and Andrey Sakharov. He declines a peerage, is awarded the Agnelli Prize for ethics, campaigns against philistine architecture in London and Jerusalem, helps run the National Gallery and Covent Garden, and talks at length to his biographer. He reflects on the ideas for which he is famous – especially liberty and pluralism – and there is a generous leavening of the conversational brilliance for which he is also renowned, as he corresponds with friends about politics, the academic world, music and musicians, art and artists, and writers and their work, always displaying a Shakespearean fascination with the variety of humankind. Affirming is the crowning achievement both of Berlin’s epistolary life and of the widely acclaimed edition of his letters whose first volume appeared in 2004. (shrink)

ABSTRACT According to edenic idealism, our ordinary object terms refer to items in the manifest world—the world of primitive objects and properties presented in experience. I motivate edenic idealism as a response to scenarios where it is difficult to match the objects in experience with corresponding items in the external world. I argue that edenic idealism has important semantic advantages over realism: it is the most intuitive view of what we are actually talking about when we use terms for objects.

Recently, many philosophers have claimed that the world has an ordered, hierarchical structure, where entities at lower ontological levels are said to metaphysically ground entities at higher ontological levels. Other philosophers have recently claimed that our language has an ordered, hierarchical structure. Semantically primitive sentences are said to conceptually ground less primitive sentences. It’s often emphasized that metaphysical grounding is a relation between things out in the world, not a relation between our sentences. But conflating these relations is easy to (...) do, given that both types of grounding are expressed by non-causal “in-virtue-of” claims. The purpose of this paper is to clarify the relation between metaphysical and conceptual grounding. I argue that conceptual and metaphysical grounding are exclusive: if a given in-virtue-of claim involves conceptual grounding, then it does not involve metaphysical grounding. I also develop some heuristics for deciding which type of grounding is relevant in a given case. These heuristics suggest that many proposed cases of metaphysical grounding do not actually involve metaphysical grounding at all. (shrink)

In this paper, I clarify the relation between two types of grounding: metaphysical and conceptual. Metaphysical grounding relates entities at more and less fundamental ontological levels. Conceptual grounding relates semantically primitive sentences and semantically derivative sentences. It is important to distinguish these relations given that both types of grounding can underwrite non-causal “in-virtue-of” claims. In this paper, I argue that conceptual and metaphysical grounding are exclusive: if a given in-virtue-of claim involves conceptual grounding, then it does not involve metaphysical grounding. (...) I then present two heuristics for deciding which type of grounding is relevant to a given case. These heuristics suggest that certain proposed cases of metaphysical grounding may not actually involve metaphysical grounding at all. (shrink)

According to the idealist, facts about phenomenal experience determine facts about the physical world. Any such view must account for illusions: cases where there is a discrepancy between the physical world and our experiences of it. In this paper, I critique some recent idealist treatments of illusions before presenting my own preferred account. I then argue that, initial impressions notwithstanding, it is actually the realist who has difficulties properly accounting for illusions.

Many philosophers have argued that large language models (LLMs) subvert the traditional undergraduate philosophy paper. For the enthusiastic, LLMs merely subvert the traditional idea that students ought to write philosophy papers “entirely on their own.” For the more pessimistic, LLMs merely facilitate plagiarism. We believe that these controversies neglect a more basic crisis. We argue that, because one can, with minimal philosophical effort, use LLMs to produce outputs that at least “look like” good papers, many students will complete paper assignments (...) in a way that fails to develop their philosophical abilities. We argue that this problem exists even if students can produce better papers with AI and even if instructors can detect AI-generated content with decent reliability. But LLMs also create a pedagogical opportunity. We propose that instructors shift the emphasis of their assignments from philosophy papers to “LLM dialogues”: philosophical conversations between the student and an LLM. We describe our experience with using these types of assignments over the past several semesters. We argue that, far from undermining quality philosophical instruction, LLMs allow us to teach philosophy more effectively than was possible before. (shrink)

We argue that indeterminate probabilities are not only rationally permissible for a Bayesian agent, but they may even be rationally required . Our first argument begins by assuming a version of interpretivism: your mental state is the set of probability and utility functions that rationalize your behavioral dispositions as well as possible. This set may consist of multiple probability functions. Then according to interpretivism, this makes it the case that your credal state is indeterminate. Our second argument begins with our (...) describing a world that plausibly has indeterminate chances. Rationality requires a certain alignment of your credences with corresponding hypotheses about the chances. Thus, if you hypothesize the chances to be indeterminate, your will inherit their indeterminacy in your corresponding credences. Our third argument is motivated by a dilemma. Epistemic rationality requires you to stay open-minded about contingent matters about which your evidence has not definitively legislated. Practical rationality requires you to be able to act decisively at least sometimes. These requirements can conflict with each other-for thanks to your open-mindedness, some of your options may have undefined expected utility, and if you are choosing among them, decision theory has no advice to give you. Such an option is playing Nover and Hájek’s Pasadena Game , and indeed any option for which there is a positive probability of playing the Pasadena Game. You can serve both masters, epistemic rationality and practical rationality, with an indeterminate credence to the prospect of playing the Pasadena game. You serve epistemic rationality by making your upper probability positive-it ensures that you are open-minded. You serve practical rationality by making your lower probability 0-it provides guidance to your decision-making. No sharp credence could do both. (shrink)

Many theorists have proposed that we can use the principle of indifference to defeat the inductive sceptic. But any such theorist must confront the objection that different ways of applying the principle of indifference lead to incompatible probability assignments. Huemer offers the explanatory priority proviso as a strategy for overcoming this objection. With this proposal, Huemer claims that we can defend induction in a way that is not question-begging against the sceptic. But in this article, I argue that the opposite (...) is true: if anything, Huemer’s use of the principle of indifference supports the rationality of inductive scepticism. (shrink)

ABSTRACTAccording to many naturalists, our ordinary conception of the world is in tension with the scientific image: the conception of the world provided by the natural sciences. But in this paper, I present a critique of naturalism with precedents in the post-Kantian idealist tradition. I argue that, when we consider our actual linguistic behavior, there is no evidence that the truth of our ordinary judgments hinges on what the scientific image turns out to be like. I then argue that the (...) best explanation of this result is that the norms and presuppositions operating in ordinary discourse are different from the norms and presuppositions operating in scientific discourse. So naturalistic attempts to undermine the manifest image are illegitimate attempts to critique a practice ‘from the outside’. (shrink)

ABSTRACT Certain features of our conceptual scheme seem necessary for subjects with our basic nature: we cannot imagine humans accomplishing their basic projects without having a conceptual scheme with these features. Other aspects of our conceptual scheme seem more contingent: we can imagine communities effectively using a somewhat different conceptual scheme. Conceptual cartography is the project of investigating the necessity and contingency of the various features of conceptual schemes. The project of conceptual cartography has not received much explicit methodological attention. (...) But in this paper, I argue that conceptual cartography has important implications for the study of conceptual engineering. I also provide a general framework for thinking about conceptual cartography. (shrink)

This article proposes a unified theory of the relationship between corporate social performance (CSP) and corporate financial performance (CFP). The theory provides a framework for rationalizing the various and contradictory findings in past empirical research. The theory is based on the parallels between the business and CSR domains, and thus draws on models from economics.

Structural realists claim that we should endorse only what our scientific theories say about the structure of the unobservable world. But according to Newman’s Objection, the structural realist’s claims about unobservables are trivially true. In recent years, several theorists have offered responses to Newman’s Objection. But a common complaint is that these responses “give up the spirit” of the structural realist position. In this paper, I will argue that the simplest way to respond to Newman’s Objection is to return to (...) one of the standard motivations for adopting structural realism in the first place: the No Miracles Argument. Far from betraying the spirit of structural realism, the solution I present is available to any theorist who endorses this argument. (shrink)

"A celebrated master of the spoken as well as the written word, Isaiah Berlin here gives us a rare memoir in the form of a dialogue." "Isaiah Berlin is renowned the world over for his analysis of the ideas that have influenced or transformed societies. He has a deep commitment to liberty and pluralism, and has devoted the half century and more of his professional life as a teacher and lecturer to exploring the conditions that allow these ideals (...) to flourish, and those that threaten them." "Berlin here intersperses insights into the development of his ideas and political philosophy with rich personal reminiscences. He discusses Machiavelli, Marx, Vico, Herder, and Herzen, among others, and their influence over him." "As he leads us from Petrograd to Oxford, Washington, Moscow, London, and Jerusalem, he speaks of his friends and contemporaries: W. H. Auden, Stephen Spender, Igor Stravinsky, A. J. Ayer, Bertrand Russell, and many others. He tells of his moving encounters with Anna Akhmatova, Boris Pasternak, and Chaim Weizmann, and of his passion for music and literature."

'People are my landscape', Isaiah Berlin liked to say, and nowhere is the truth of this observation more evident than in his letters. He is a fascinated watcher of human beings in all their variety, and revels in describing them to his many correspondents. His letters combine ironic social comedy and a passionate concern for individual freedom. His interpretation of political events, historical and contemporary, and his views on how life should be lived, are always grounded in the personal, (...) and his fiercest condemnation is reserved for purveyors of grand abstract theories that ignore what people are really like. This second volume of Berlin's letters takes up the story when, after war service in the United States, he returns to life as an Oxford don. Against the background of post-war austerity, the letters chart years of academic frustration and self-doubt, the intellectual explosion when he moves from philosophy to the history of ideas, his growing national fame as broadcaster and lecturer, the publication of some of his best-known works, his election to a professorship, and his reaction to knighthood. Berlin's visits to American universities, where he sees McCarthyism at work, and his journeys eastward - to Europe, Palestine (and later Israel) and the Soviet Union - inspire acute and often very funny pen-pictures. His political contacts yield an inside view of major world events - the creation of Israel, the Suez Crisis, the Cold War. Many letters provide illuminating, accessible commentary on his ideas. These are the years, too, of momentous developments in his private life: the bachelor don's loss of sexual innocence, the emotional turmoil of his father's death, his courtship of a married woman and transformation into husband and stepfather. Above all, these revealing letters vividly display Berlin's effervescent personality - often infuriating, but always irresistible. (shrink)

"Political Ideas in the Twentieth Century", Historical Inevitability", "Two Concepts of Liberty", "John Stuart Mill and the Ends of Life". These four essays deal with the various aspects of individual liberty, including the distinction between positive and negative liberty and the necessity of rejecting determinism if we wish to keep hold of the notions of human responsibility and freedom.

Foveated stimuli receive visual processing that is quantitatively and qualitatively different from nonfoveated stimuli. At normal interpersonal distances, people move their eyes around another’s face so that certain features receive foveal processing; on any given fixation, other features therefore project extrafoveally. Yet little is known about the processing of extrafoveally presented facial features, how informative those extrafoveally presented features are for face perception (e.g., for assessing another’s emotion), or what processes extract task-relevant (e.g., emotion-related) cues from facial features that first (...) appear outside the fovea, and how these processes are implemented in the brain.

The objective of this article is to examine the nature of individual and social responses to the nuclear threat from psychological and sociological perspectives on ignorance. It is argued that a constructed and managed ignorance concerning the nuclear threat serves many functions, structuring an individual and social reality which is reassuring, meaningful, and both individually and collectively self-serving. A sociology of ignorance framework is employed to articulate the possible benefits of “not knowing about” and collaboratively “not dealing with” the nuclear (...) threat, as well as to define the longer-term costs of ignoring this threat. The distinctive roles played by various kinds of ignorance regarding this important issue are investigated, and the conventional wisdom that knowledge of the consequences of a nuclear war is the only way to prevent its occurrence is challenged.

"Out of the crooked timber of humanity, no straight thing was ever made."--Immanuel Kant Isaiah Berlin was one of the most important philosophers of the twentieth century--an activist of the intellect who marshaled vast erudition and eloquence in defense of the endangered values of individual liberty and moral and political pluralism. In the Crooked Timber of Humanity he exposes the links between the ideas of the past and the social and political cataclysms of our present century: between the Platonic (...) belief in absolute Truth and the lure of authoritarianism between the eighteenth-century reactionary ideologue Joseph de Maistre and twentieth-century fascism between the romanticism of Schiller and Byron and the militant--and sometimes genocidal--nationalism that convulses the modern world.

Liberty is an expanded edition of Isaiah Berlin's classic of liberalism, Four Essays on Liberty. Berlin's editor Henry Hardy has incorporated a fifth essay, as Berlin wished, and added further pieces on the same topic, so that Berlin's principal statements on liberty are available together for the first time. He also describes the gestation of the book and throws further biographical light on Berlin's preoccupation with liberty in appendices drawn from his unpublished writings.

Laws of nature have various roles in scientific practice. It is widely agreed that an adequate theory of lawhood ought to align with the roles that scientists assign to the laws. But philosophers disagree over whether Humean laws or non-Humean laws are better at filling these roles. In this paper, I provide an argument for settling this dispute. I consider possible situations in which scientists receive conclusive evidence that—according to the non-Humean—falsifies their beliefs about the laws, but which—according to the (...) Humean—does not falsify their beliefs about the laws. I argue that, in these possible scenarios, all law-related aspects of scientific practice would remain unchanged. In other words, scientists would treat the regularities “preferred” by the Humean as the laws of nature. On this basis, I conclude that non-Humean laws fail to align with scientific practice.

This paper focuses on one matter that poses a problem for both human judges and standard probability frameworks, namely the assumption of a unique (privileged) and complete partition of the state-space of possible events. This is tantamount to assuming that we know all possible outcomes or alternatives in advance of making a decision, but it is clear that there are many practical situations in prediction, diagnosis, and decision-making where such partitions are contestable and/or incomplete. The paper begins by surveying the (...) impact of partitions on the choice of priors in formal probabilistic updating frameworks, and on human subjective probability judgements. That material is followed by an overview of strategies for dealing with partition dependence, including considerations of how a rational agent's preferences may determine the choice of a partition.

Many quantitative scales are constructed using cutoffs on a continuum with scores assigned to the cutoffs. This paper develops a framework for using or constructing such scales from a decision-making standpoint. It addresses questions such as: How many distinct thresholds or cutoffs on a scale (i.e., what levels of granularity) are useful for a rational agent? Where should these thresholds be placed given a rational agent’s preferences and risk-orientation? Do scale score assignments have any bearing on decision-making and if so, (...) how should scores be assigned? Given two possible states of nature , an ordered collection of alternatives from which one is to be selected depending on the probability that A is the case, a simple expected utility condition stipulates when adjacent alternatives are distinguishable and determines the threshold odds separating them. Threshold odds and utilities are mapped onto scale scores via a simple distance model. The placement of the thresholds reflects relative concern over decisional consequences given A versus consequences given ∼ A. Likewise, it is shown that scale scores reflect risk-aversion or risk-seeking not only with respect to A versus ∼ A but also with respect to the rank of the R j . Connections are drawn between this framework and rank-dependent expected utility (RDEU) theory. Implications are adumbrated for both machine and human decision-making. (shrink)

The major cause of death from cancer is the relentless growth of metastases that are resistant to conventional therapy. The pathogenesis of a metastasis is complex and requires that tumor cells complete a sequence of potentially lethal interactions with various host factors. The finding in 1973 that metastasis is selective process and the finding in 1977 that malignant neoplasms are heterogeneous and contain few preexisting metastatic subpopulations have added a new dimension to our understanding of cancer and its spread. This (...) understanding is now contributing to the design of better therapies against disseminated metastasis. (shrink)

The sociology of knowledge and related work in social psychology have been biased towards overvaluing shared perspectives and the attainment of certainty. This paper moves to fill a theoretical gap created by relative inattention to the roles of nonshared perspectives and uncertainty by outlining a middle-range theory of the connections between human interests and uncertainty. It is proposed that individuals and groups find instrumental uses for uncertainty, just as they do for other states of mind, and that these uses arise (...) from particular interests which characteristically belong to certain types of individuals or groups.
