Several forms of dietary learning have been identified in humans. These include flavor–flavor learning, flavor–postingestive learning , and learned satiety. Generally, learning is thought to occur in the absence of contingency or demand awareness. However, a review of the literature suggests that this conclusion may be premature because measures of awareness lack the rigor that is found in studies of other kinds of human learning. If associations do configure outside awareness then this should be regarded as a rare instance of (...) automatic learning. Conversely, if awareness is important, then successful learning may be governed by an individual’s beliefs and predilection to attend to stimulus relationships. For researchers of dietary learning this could be critical because it might explain why learning paradigms have a reputation for being unreliable. Since most food preferences are learned, asking questions about awareness can also tell us something fundamental about everyday dietary control. (shrink)

In order to understand ongoing activity, observers segment it into meaningful temporal parts. Segmentation can be based on bottom‐up processing of distinctive sensory characteristics, such as movement features. Segmentation may also be affected by top‐down effects of knowledge structures, including information about actors' intentions. Three experiments investigated the role of movement features and intentions in perceptual event segmentation, using simple animations. In all conditions, movement features significantly predicted where participants segmented. This relationship was stronger when participants identified larger units than (...) when they identified smaller units, and stronger when the animations were generated randomly than when they were generated by goal‐directed human activity. This pattern suggests that bottom‐up processing played an important role in segmentation of these stimuli, but that this was modulated by top‐down influence of knowledge structures. To describe accurately how observers perceive ongoing activity, one must account for the effects of distinctive sensory characteristics, the effects of knowledge structures, and their interactions.

Scholars in both digital humanities and media studies have noted an apparent disconnect between computation and the interpretive methods of the humanities. Alan Liu has argued that literary scholars employing digital methods encounter a “meaning problem” due to the difficulty of reconciling algorithmic methods with interpretive ones. Conversely, the media scholar Friedrich Kittler has questioned the adequacy of hermeneutics as a means of studying computers. This paper argues that that this disconnect results from a set of contingent decisions made in (...) both humanistic and mathematical disciplines in the first half of the nineteenth century that delineated, with implications that continue to resonate in the present day, which aspects of human activity would come to be formalized in algorithms and which would not. I begin with a discussion of Nicolas de Condorcet, who attempted, at the height of the 1789 revolution, to turn algebra into a universal language; his work, I argue, exemplifies the form of algorithmic thinking that existed before the Romantic turn. Next, I discuss William Wordsworth’s arguments about the relationship of poetry and science. While Wordsworth is sometimes viewed as a critic of science, I argue that his polemic is specifically targeted at highly politicized projects like Condorcet’s that sought to supplant existing modes of thought with scientific rationality. Finally, I demonstrate the importance of Romantic thought for George Boole, creator of the logic system that would eventually form the basis of digital electronics. The reason Boole was able to succeed where Condorcet had failed, I argue, was that Romantic notions of culture enabled him to reconcile a mechanical view of mathematical reasoning with an organic view of the development of meaning—a dichotomy that remains a key assumption of computer interfaces in the twenty-first century.

In this introduction to Part 1 of “Contextualism—the Next Generation: Symposium on the Future of a Methodology,” the editor of Common Knowledge, a “journal of left-wing Kuhnian opinion,” reports that the new symposium responds to contextualist criticism of the previous CK symposium, which was on xenophilia. The content of the earlier symposium met with objections, from contextualists, on the grounds of methodology, and the new symposium questions the methodology of contextualism for the limits that it places on content as well (...) as on normative aims and degree of focus. Tracing the origins of contextualism to Kuhn and his theory that paradigms of scientific knowledge are incommensurable, this essay then argues that Kuhnian method is formal, with scant concern for content, and that Kuhn’s work was vatic, more than philosophical or historical. Kuhn’s depiction of his sudden, blinding realization that Aristotelian physics is correct in its own context is assessed as an ironic application of biblical scenes of revelation to what is, essentially, a process of scrupulous, piecemeal scholarship. What Kuhn unknowingly wanted, the essay concludes, was a combination of contextualism and phenomenology, as a means of knowing what it was like to believe in Aristotelian, as opposed to modern, concepts of matter, quality, space, void, position, change, and motion. The essay then introduces the first contribution to the new symposium: a monograph retrieving geometrical and taxonomic—Euclidean and Theophrastan—idioms of discourse about fictional characters and inquiring into their changing affective content.

This paper is concerned with the uses of history in science. It focuses in particular on Anglo-American genetics and on university textbooks—where the canon of a science is consolidated, as the heterogeneous approaches and controversies of its practice are rendered unified for its reproduction. Tracing the emergence and eventual standardization of geneticists’ use of a case-based method of teaching in the 1920s–1950s, this paper argues that geneticists created historical environments in their textbooks—spaces in which students developed an understanding of the (...) laws of genetics through simulations of their discovery and use. Witnessing the unfolding of Mendel’s and Morgan’s experiments and performing genetic crosses on paper, students learned not only the rules that were explicitly taught as such, but also the experientially-based, tacit skills needed to find and follow these rules. This didactic system taught them how to go on when confronting new situations, and in doing so, provided geneticists with an important disciplinary tool, freeing the first steps of their student’s enculturation from the physical infrastructure of the laboratory.

water paradox has long served as an argument against the Principle of Indifference. A solution to the paradox is proposed, with a view toward resolving general difficulties in applying the principle.

This paper concerns what if any obligations a “society of equals” has to criminal offenders after legal punishment ends. In the United States, when people leave prisons, they are confronted with a wide range of federal, state, and local laws that burden their ability to secure welfare benefits, public housing, employment opportunities, and student loans. Since the 1980s, these legal consequences of criminal convictions have steadily increased in their number, severity, and scope. The central question I want to ask is (...) whether the infliction of these burdensome legal consequences for those who have already been punished by the state is consistent with the ideal of equality. I argue that these collateral legal consequences violate relational egalitarian principles of justice and are thus objectionable. I conclude by examining possible objections to my argument. (shrink)

People with disabilities suffer from pervasive inequalities in employment, education, transportation, housing, and health care compared to those who are not disabled. Moreover, people with disabilities are often subject to unjustified stigma and pity. In this paper, I will explain why these disadvantages violate relational egalitarian principles of justice. As I will show, my argument can account for both kinds of inequality that disabled people face.

This paper concerns the question of what makes disability discrimination morally objectionable. When I refer to disability discrimination, I am focusing solely on a failure or denial of reasonable accommodations to a disabled person. I argue a failure to provide reasonable accommodations is wrong when and because it violates principles of relational equality. To do so, I examine four accounts of wrongful discrimination found in the literature and apply these theories to disability discrimination. I argue that all of these accounts (...) leave us wanting because they have implausible implications or other limitations. I then defend my relational egalitarian theory of wrongful disability discrimination. I argue why principles of relational equality can explain the wrongness of failing to accommodate a disabled person. I will then illustrate how my account can identify plausible instances of disability discrimination while avoiding implausible implications. Finally, I discuss some further complications with my account while highlighting its benefits. Importantly, my argument can capture the distinctive wrongness of disability law and policy’s reasonable accommodation mandates. (shrink)

In this piece, the editor of Common Knowledge introduces a long-term project titled “Antipolitics: Symposium in Memory of György Konrád.” Konrád, who died in 2019, was a founding member of the Common Knowledge editorial board, and the symposium is meant to find present-day applications for the arguments of his book Antipolitics, published in 1982 in Hungarian. Although written under Cold War conditions and to that extent dated, the book is directed against politics and politicians as such: “What Machiavelli's Prince is (...) to would-be rulers, Antipolitics should be for those resistant to being ruled — a treasury of axioms and apothegms,” which this editorial collects, updates, and analyzes. Given that democratic systems and constitutions are “open and subject to further development,” Konrád urges us to devise and run experiments in governance that apply “creative imagination” to problems that, in better times, we might leave to politicians to resolve. “The crisis for democracy today,” Perl argues, “is that bad government (as Konrád, Václav Havel, and Adam Michnik defined it in the 1980s) appears to be what various electorates crave and therefore choose.” Realizing that elections produce, as Aristotle said, oligarchy rather than democracy, we should rethink majority rule and experiment with sortition as a counterpolitical means of self-government.

A wide-ranging history of the intellectual developments that produced the modern idea of the algorithm. Bringing together the histories of mathematics, computer science, and linguistic thought, Language and the Rise of the Algorithm reveals how recent developments in artificial intelligence are reopening an issue that troubled mathematicians long before the computer age. How do you draw the line between computational rules and the complexities of making systems comprehensible to people? Here Jeffrey M. Binder offers a compelling tour of four (...) visions of universal computation that addressed this issue in very different ways: G. W. Leibniz's calculus ratiocinator; a universal algebra scheme Nicolas de Condorcet designed during the French Revolution; George Boole's nineteenth-century logic system; and the early programming language ALGOL, whose name is short for algorithmic language. These episodes show that symbolic computation has repeatedly become entangled in debates about the nature of communication. To what extent can meaning be controlled by individuals, like the values of a and b in algebra, and to what extent is meaning inevitably social? By attending to this long-neglected question, we come to see that the modern idea of the algorithm is implicated in a long history of attempts to maintain a disciplinary boundary separating technical knowledge from the languages people speak day to day. Machine learning, in its increasing dependence on words, now places this boundary in jeopardy, making its stakes all the more urgent to understand. The idea of the algorithm is a levee holding back the social complexity of language, and it is about to break. This book is about the flood that inspired its construction. (shrink)

In this piece, the editor of Common Knowledge offers excerpts from his two-year correspondence with a reader in Hong Kong, who was drawn to arguments made in the journal about maintaining “quietism and resistance in the face of vile behavior.” In the summer and fall of 2019, during the insurrection in Hong Kong, his correspondent shifts rapidly from taking comfort in CK’s defense of quietism to a full embrace of “uncivil disobedience.” She implies that the solidarity the editor expresses with (...) Hong Kong is merely rhetorical, and he responds by writing this article and quoting in it the entire text of the 1984 Joint Declaration of the Chinese and British governments on the question of Hong Kong. The declaration’s guarantees of autonomy and civil rights appear in bold italics. The editor concludes by suggesting that it falls to the United Nations Security Council to enforce the terms of the treaty. (shrink)

In this introduction to the first installment of the Common Knowledge symposium on xenophilia, the editor explains the rationale of the new project, citing increases in aggressive xenophobia internationally. He comments on the intergroup-relations theorist Todd Pittinsky's argument that, since tolerance is not logically the antithesis of negative feelings toward out-groups, even long-established traditions of toleration are inadequate to prevent intergroup aggression. Pittinsky proposes that tolerance be replaced, as a principle of peacekeeping, by the encouragement of positive feelings toward out-groups, (...) and the author of this essay responds by showing how the Freudian theory of ambivalence and the history of literature on which Freud drew in constructing it support Pittinsky's viewpoint. Enemies regularly fall in love, above all in Shakespearean drama, which Freud explains by arguing that all human relations are love-hate relations. Thus, this essay suggests, it takes as much psychic energy to repress the love in what appear to be relationships of hatred as to repress the hatred in what appear to be relationships of love. There is a metaphysical component as well to this argument: the xenophobe and xenophile equally presuppose that the identity principle is applicable to society as well as to mathematics; both assume that each discrete social group is self-identical and differs from all other groups more or less radically. The main difference between –phile and –phobe is the latter's relative incapacity to live with ambivalence. Given these arguments, one must expect to find negative as well as positive motives in the etiology and conduct of xenophilia—and the first installment of the Common Knowledge symposium is said to focus on cases of xenophilia in which varieties of enmity accompany that singular and underrated variety of love.

In this introduction to part 4 of the Common Knowledge symposium “Peace by Other Means,” the journal's editor assesses the argument made by Peace, the spokesperson of Erasmus in his Querela Pacis, that the desire to impute and avenge wrongs against oneself is insatiable and at the root of both individual and social enmities. He notes that, in a symposium about how to resolve and prevent enmity, most contributions have to date expressed caveats about how justice and truth must take (...) precedence over peace, how recovery from ill treatment may be impossible, how quietism is not a moral option, and how realism demands a national policy and a personal strategy of, at best, contingent forgiveness. He concedes that the attitudes of those opposed to quietism are healthy but suggests that there may be goods worthier than health of human devotion. This essay concludes that the main differences between what it terms “judgmental” and “irenic” regimes are disagreements over anthropology and metaphysics. The presumptions that truths are objectively knowable and that human beings are moral and rational agents characterize judgmental regimes; irenic regimes are characterized by disillusionment with those assumptions.

This editorial note introduces the second of three issues of Common Knowledge dedicated to experiments in scholarly form. The first appeared in Winter 1996 and was introduced by a dialogue between two editorial board members, Greil Marcus and Hugh Kenner, who differed over whether tampering with set scholarly forms should be regarded as a serious business or as a matter of fun. Philosophically, this note explains, the journal takes exception to distinctions of the form-versus-content variety — a resistance that stems (...) from desire for peaceful transactions in intellectual life. But though the desire for peace, like any other, can be uncompromising, this one recoils from its own strength and requires indirect expression. One way, it is argued, to achieve indirection is to tamper with forms in which a strong position finds natural expression. Tampering, for instance, with the distinction between narrative history and fiction, or between discursive philosophy and poetry, is a time-honored maneuver. Hence the appearance in this special issue of three pieces on microhistory, along with the first installment of a two-part symposium on “lyric philosophy” and a “pseudepigraphon” premised on its author's conviction that not-for-credit truths are credible only if they appear to be fabrications.

Paul B. Thompson’s From the Field to Fork: Food Ethics for Everyone explains the growing number of ways that food connects to ethical questions concerning our consumption, production, storage, and distribution of food. Although this book serves as an introduction to food ethics for non-experts, professionals in agricultural science and food production, food activists, and philosophers will have a lot to learn from Thompson’s insight, careful argumentation, and mastery of the economic, scientific, and political issues that ground our current debates (...) about food. In my comments, I will first briefly provide an overview of Thompson’s thoughtful book. I will explain the methodology employed in this book and how his methodology applies to specific philosophical questions within food ethics. I will focus my commentary on how Thompson frames the ethics of diet and obesity. I will then raise a few questions concerning food choice and paternalism that were omitted from this book, but that I think raise substantial ethical concerns in affluent countries. I will close with a very brief comment on Thompson’s methodology. (shrink)

Data gathered by investigators are used to test the validity of a specific scientific hypothesis. When the hypothesis relates to the biology of a disease or its treatment, then data sets may contain specific and identifiable medical information. Since the information in a clinical data set was gathered to test a specific hypothesis and there is usually a sponsor interested in the outcome, the issue of who owns the data is a critical one. In my opinion, data from both publicly (...) and privately funded research should be made available, in a format that protects confidentiality and intellectual property rights, to interested and responsible parties within a reasonable period of time after publication.

A simple tool is provided to assist researchers in assessing contributions to a scientific publication, for ease in evaluating which contributors qualify for authorship, and in what order the authors should be listed. The tool identifies four phases of activity leading to a publication—Conception and Design, Data Acquisition, Analysis and Interpretation, and Manuscript Preparation. By comparing a project participant’s contribution in a given phase to several specified thresholds, a score of up to five points can be assigned; the contributor’s scores (...) in all four phases are summed to yield a total “contribution score”, which is compared to a threshold to determine which contributors merit authorship. This tool may be useful in a variety of contexts in which a systematic approach to authorial credit is desired. (shrink)

In this introduction to Part 1 of the Common Knowledge symposium, “Fuzzy Studies,” the journal's editor discusses four essays from the 1980s by Richard Rorty, in which Rorty chose to associate himself with various neopragmatists, Continental thinkers, and “left-wing Kuhnians” under the rubric of the “new fuzziness.” The term had been introduced as an insult by a philosopher of science with positivist leanings, but Rorty took it up as an “endearing” compliment, arguing that “to be less fuzzy” was also to (...) be “less genial, tolerant, open-minded, and fallibilist.” He defined the “new fuzziness” as “an attempt to blur just those distinctions between the objective and subjective and between fact and value which the critical conception of rationality has developed.” This introduction also examines W. V. Quine's essay “Speaking of Objects”, which describes objects as fuzzy “half-entities”; Clifford Geertz's essay “Blurred Genres”, which advises social scientists that being “taxonomically upstanding” is futile; and Lofti Zadeh's article “The Concept of a Linguistic Variable and Its Application to Approximate Reasoning”, which abandons “Aristotelian, bivalent logic” in favor of a “fuzzy logic” based on Zadeh's “fuzzy set theory.” This introductory piece relates these theoretical works of the past half-century to the sorites paradox and to classical issues of vagueness raised and still unresolved in Western philosophy. Returning then to Rorty, the author questions how Rorty expected his endorsement of the “new fuzziness” to be applied, as proposed, to theology and politics. Suggesting that such applications are the natural work of historians, the author, having asked the historian Natalie Zemon Davis for comment, then quotes her response—which associates fuzzy studies, “common knowledge,” and peacemaking—at length.

As part of a larger study eliciting Canadian producer and non-producer views about animal welfare, open-ended, semi-structured interviews were used to explore opinions about animal welfare of 20 Canadian pig producers, most of whom were involved in confinement-based systems. With the exception of the one organic producer, who emphasized the importance of a “natural” life, participants attached overriding importance to biological health and functioning. They saw their efforts as providing pigs with dry, thermally regulated, indoor environments where animals received abundant (...) feed, careful monitoring and where prospective disease outbreaks could be minimized and controlled. Emphasis was also placed on low-stress handling and agreeable working conditions which were believed to promote good animal care. The fact that pigs tend to respond to such conditions with steady growth reinforced the belief that good welfare was provided. Participants supported the use of sow gestation stalls, but with some reservations, and expressed concern about welfare problems that could occur if sows were grouped. Invasive procedures (castration, tail-docking, teeth clipping) were recognized as painful but were accepted because they were seen as: (1) necessary for sales or management; (2) satisfactory trade-offs to prevent worse welfare problems such as injury or infection; or (3) sufficiently short-term to be relatively unimportant. Participants were adamantly opposed to animal neglect and some welcomed actions of animal protectionists that expose poor care. Producers also welcomed natural-science-based approaches to improving animal welfare. The findings contribute to a broader effort to identify overlapping values among different stakeholder groups as a basis for formulating mutually agreeable, farm animal care and handling polices.

In this introduction to part 3 of the Common Knowledge symposium “Antipolitics,” the journal's editor argues that, apart from sortition, the best guarantees of safety in a democracy are, first, to augment judicial oversight of all political processes and, second, to exclude politicians from the process of selecting judges. “There can never be too much judicial interference,” he writes, “in what politicians regard as their domain.” The author reached this conclusion during attempts by the newly elected Israeli government, in the (...) spring of 2023, to make itself absolute by eliminating checks on its conduct that the Supreme Court had been developing and applying since the 1950s. Traditional Jewry and Judaism being notoriously hypernomian, the resistance to legality on the part of the ruling coalition has conveyed an aura of antinomian heresy. The choice in Israel appears to be between antipolitics and antinomianism, rather than between Left and Right politically—and the antipolitical model in Israel of a superintendent judiciary and an autonomous attorney general is arguably superior to the American prototype, even from the perspective (“all men are created equal..., endowed by their Creator with certain unalienable Rights”) that we have come to regard as quintessentially American.

This introduction to the third and final part of the Common Knowledge symposium “Unsocial Thought, Uncommon Lives” is reprinted here in a special issue of representative pieces from the journal’s first twenty-five years. The title is taken from an article by Isaiah Berlin in CK. Perl’s essay argues against the Aristotelian presumption that “man is a social animal” and explains that the CK symposium on unsocial thought was meant to substantiate that “societies do as a rule smother instinctive behaviors, but (...) in the process they also as a rule incarnate the least respectable instincts with greater force than individuals can do independently.... If even heroism and altruism, let alone standard social conduct, are oblique expressions of aggression, cruelty, and the will to power, then the obvious conclusion to reach is that human beings are not fit company for each other.... The standard means of veering off from this conclusion is to blame one’s own society, or aspects of contemporary society, and then to propose improvements. Historically, evidence suggests, efforts of this kind are opportunities for controversy and thus for exercise of the will to power. Social order is such that even the discussion of social order occasions conflict.” Perl goes on to argue that individualists and communitarians are “fundamentally in accord”: they are “teams” agreeing to the rules of a dubious conflict from which only “stylites, dendrites, and mendicants” have done what is required to exempt themselves.
