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.

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 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)

This essay introduces the second of three installments of an “elegiac symposium” in Common Knowledge on figures and concepts devalued in what Thomas Kuhn refers to as “paradigm shifts.” The essay suggests that Kuhn’s idea is provincial, in three specified senses, and then goes on to show how differently Japanese culture regards and manages major change. The author of this introduction, who is also the journal’s editor, begins by evaluating a triptych of 1895 by Toshikata as a response to the (...) seemingly revolutionary changes brought by the Meiji Restoration a generation before. He then goes on to discuss, as exemplary of Japanese attitudes toward change, the Shinto ritual during which the sacred shrines of Ise Jingū are torn down and rebuilt every twenty years. The essay concludes by explaining how the impetus for this ritual is also involved in less-exalted aspects of Japanese culture; for example, in the peculiarities of the market for ukiyo-e woodblock prints. Overall, this essay shows that Japanese ways of regarding concepts such as “old” and “new,” “continuity” and “change,” differ so radically from those presupposed in the West that the latter should be regarded as provincial rather than as universally valid.

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.

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 the last homily he gave before becoming Pope Benedict XVI, Cardinal Joseph Ratzinger described modern life as ruled by a “dictatorship of relativism which does not recognize anything as definitive and whose ultimate goal consists solely” of satisfying “the desires of one’s own ego.” An eminent scholar familiar with the centuries-old debates over relativism, Ratzinger chose to oversimplify or even caricature a philosophical approach of great sophistication and antiquity. His homily depicts the relativist as someone blown about “by every (...) wind of doctrine,” whereas the relativist sticks firmly to one argument—that human knowledge is not absolute. Gathering prominent intellectuals from disciplines most relevant to the controversy—ethics, theology, political theory, anthropology, psychology, cultural studies, epistemology, philosophy of science, and classics—this special double issue of _Common Knowledge_ contests Ratzinger’s denunciation of relativism. One essay relates the arguments of Ratzinger to those of two other German scholars—the conservative political theorist Ernst Wolfgang Böckenförde and the liberal philosopher and sociologist Jürgen Habermas—since all three men assume that social order depends on the existence of doctrinal authority. The contributors here argue for an intellectual and social life free of the desire for an “infantilizing” authority. One proposes that the Christian god is a relativist who prefers limitation and ambiguity; another, initially in agreement with Ratzinger about the danger relativism poses to faith and morals, then argues that this danger is what makes relativism valuable. The issue closes with the first English translation of an extract from a book on Catholic-Jewish relations by Cardinal Carlo Maria Martini, one of the Catholic Church’s most progressive figures. _Contributors_.

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.

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.

The Theory of Event Coding deals with brief events but has implications for longer, complex events, particularly goal-directed activities. Two of the theory's central claims are consistent with or assumed by theories of complex events. However, the claim that event codes arise from the rapid activation and integration of features presents challenges for scaling up to larger events.

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)

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 essay review of Megan Quigley's Modern Fiction and Vagueness: Philosophy, Form, and Language, the editor of Common Knowledge comments on the explicit relationship between that book's arguments and those of the journal's six-part series “Fuzzy Studies: A Symposium on the Consequence of Blur,” published in 2011–13. He points out that there are aesthetic forms and concepts of vagueness that are related only tangentially to what analytic philosophers, in treating the “sorites paradox” and its implications, have meant by the (...) term, and he suggests that this book suffers by limiting itself to Anglophone works, when the most relevant work is perhaps in French, and by limiting its reach to fiction, when the most relevant genres of art are perhaps poetry, painting, and music. The review concludes by regretting Quigley's making T. S. Eliot her study's straw man and by observing not only that her interpretation of Eliot's relationship to analytic philosophy is demonstrably incorrect but also that there is no point in valorizing vagueness or “fuzzy studies” if the upshot is not a sort of mutual respect and acceptance that scientistic clarity in the arts and humanities does not foster.

Much of our behavior is guided by our understanding of events. We perceive events when we observe the world unfolding around us, participate in events when we act on the world, simulate events that we hear or read about, and use our knowledge of events to solve problems. In this book, Gabriel A. Radvansky and Jeffrey M. Zacks provide the first integrated framework for event cognition and attempt to synthesize the available psychological and neuroscience data surrounding it. This synthesis (...) leads to new proposals about several traditional areas in psychology and neuroscience including perception, attention, language understanding, memory, and problem solving.Radvansky and Zacks have written this book with a diverse readership in mind. It is intended for a range of researchers working within cognitive science including psychology, neuroscience, computer science, philosophy, anthropology, and education. Readers curious about events more generally such as those working in literature, film theory, and history will also find it of interest. (shrink)

Women are diagnosed with clinical depression at twice the rates as men. Treating depression through psychotherapy or medication both focus on changing an individual, rather than addressing socioecological influences or social roles. In the current study, participants read of systemic inequality contributing to differential rates of depression in either American men or women, or in two fictitious Australian First Nation groups. Participants then considered the acceptability and efficacy of treating depression through psychotherapy, medication, or social change. When socioecological inequities and (...) unequal social roles were presented through an unfamiliar foreign lens, participants were more likely to recognize the systemic unfairness, and endorsed social change more than psychotherapy or medication as a treatment strategy. However, when identical social inequities and social roles were presented through descriptions of American men and women, social intervention was less likely to be endorsed, and psychotherapy or medication gained in acceptability. Participants of color were also more likely to recognize and endorse social change as a strategy for treating depression, while those reporting a history of psychotropic medication for affective disorders rated medication as more effective and acceptable.

The issue of whether biological and psychological properties associated with disability can be harmful, beneficial, or neutral brings up an important philosophical question about how we evaluate disability, and disability’s impact on well-being. The debate is usually characterized as between those who argue disability is intrinsically harmful, and disability rights advocates who argue that disability is just another way of being different, in part, because disability can also provide important benefits. I argue that this debate is a false one, as (...) neither view can capture the more complicated relationship between disability and well-being. I argue that many disabilities are best understood as a kind of pro-tanto extrinsic harm that is characterized in counterfactual terms. This means that our judgments concerning disability and harm must be context-sensitive. (shrink)

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 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)

APPENDIX: The data emerging from the clinical and brain studies described above suggest that, in the case of OCD, there are two pertinent brain mechanisms that are distinguishable both in terms of neuro-dynamics and in terms of the conscious experiences that accompany them. These mechanisms can be characterized, on anatomical and perhaps evolutionary grounds, as a lower-level and a higher-level mechanism. The clinical treatment has, when successful, an activating effect on the higher-level mechanism, and a suppressive effect on the lower-level (...) one. (shrink)

Discussions of withdrawal of life support often revolve around a patient’s perceived level of suffering or lack of experience. Personhood, however, is often linked to personal agency. In the present study, 279 laypeople estimated the amount of agency and experience in hypothetical patients differing in degree of consciousness. Participants also indicated whether they would choose to maintain or terminate life support. Patients were more likely to terminate life support for a patient in a persistent vegetative state, followed by one with (...) amyotrophic lateral sclerosis and in a minimally conscious state. The decision to maintain life support was reliably predicted by perceptions of a patient’s agency but life support decisions were not significantly predicted by ratings of experience. In sum, decisions regarding maintaining life support are more influenced by perceptions of a patient’s ability to plan and act than by perceptions of a patient’s ability to feel or experience.

Theories on categorization have led to numerous technical innovations. Starting with artificial intelligence and neural models, scientists have leveraged psychological theories to drive forward innovative technology. More recently, software companies and Internet firms have implemented high technology software developed from cognitive theory. One class of systems rooted in the philosophical tradition stresses the importance of explanation and function. Another focuses on feature similarity and rule-based reasoning. Both approaches have had modest success and solve fundamental problems, but neither has achieved the (...) higher-levels of categorization found in humans. The current paper critically analyzes the various theories of categorization and their collective impact on recent technology innovations. (shrink)

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.

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)

COVID-19 is a highly contagious infection with no proven treatment. Approximately 2.5% of patients need mechanical ventilation while their body fights the infection.1 Once COVID-19 patients reach the point of critical illness where ventilation is necessary, they tend to deteriorate quickly. During the pandemic, patients with other conditions may also present at the hospital needing emergency ventilation. But ventilation of a COVID-19 patient can last for 2–3 weeks. Accordingly, if all ventilators are in use, there will not be time for (...) patients to ‘queue up’ to wait for those who arrived earlier to recover. Those who need a ventilator will die if they do not receive access to one quickly. Many nations now face the prospect that they failed to prepare appropriately for this foreseen risk of pandemic (another issue worthy of legal analysis) and that their populations will need far more ventilators than the health service can supply. For many weeks, the UK has been anticipating a surge of COVID-19 infections that could leave patients queuing in hospitals for ICU care. Luckily, social distancing has ‘flattened the curve’ and this problem might not arise. There is still a degree of risk, however, and other countries will not be so lucky. At some point, during this pandemic or the next, all countries will need to answer hard questions about whether and when scarce ICU resources (such as ventilators, beds and staff) should be either withheld or withdrawn from certain groups of patients solely for the purpose of providing them to others. Attempts to answer these questions can be found in a wide range of ICU triage protocols and ethical guidance documents, many of which embrace the foundational principle of ‘save the most lives’. Unfortunately, this worthwhile goal has generated many suggestions that could violate the law. This article identifies …. (shrink)

In his introduction to part 2 of the Common Knowledge symposium on xenophilia, the journal's editor tours the reader through two private apartments and through two public art collections in an effort to establish that aesthetically coherent mixtures of apparently immiscible objects from widely divergent cultures are possible and also morally glamorous. Xenophobia at its least reprehensible, he argues, is a fear of ecumenism and its consequences, as well as a fear of one's own conversion — of “turning Turk.” Xenophilia (...) at its most admirable is a pursuit of coherent mixtures where others cannot imagine their possibility. Bits lifted from reputedly pure and organic wholes may be transformed by means of overlap and mediated juxtaposition into a novel milieu that has a wholeness, authenticity, and charisma of its own. Such coherence depends on minds that are capable of loving what does not satisfy their narcissism and that can sense in the products of their own culture elements or signs of enervation, anomie, lack, derangement, waywardness, rigidity, preciousness, or warping. The author concludes that xenophilia neither signals nor facilitates the adulteration that xenophobes so fear. (shrink)

In his commentary on theTimaeus, the Neoplatonist Iamblichus argues that time is logically antecedent to change inasmuch as time is no mere aspect of change. Naturally, scholars appraise this thesis in light of Neoplatonic metaphysics. Nevertheless, they neglect the philological framing of this thesis, and thence the philosophical implications thereof. Only J.M. Dillon acknowledges this framing, though even Dillon does not acknowledge the philosophical implications thereof. This article illustrates the logic of said thesis vis-à-vis the Iamblichean exegesis ofTi. 38b7–c1 (Iambl.apudSimpl.in (...) Phys.1.794.21–7 Diels, Iambl.in Ti. fr. 67 Dillon). Beginning from the intuition that time is no mere aspect of change, Iamblichus argues that time can persist apart from change, and thereupon, given the Platonic notion that time is the everlasting image of Eternityquaparadigm, Iamblichus intuits that time is no mere image but everlasting in its own right, being itself a paradigm. Yet this thesis rests upon the indeterminateness of the Platonic titleτὸ παράδειγμα τῆς διαιωνίας φύσεως(‘the paradigm of a thoroughly everlasting nature’) atTi. 38b8 and, still more so, upon the reflexiveness of the ambiguousΑΥΤΩΙ(that is,αὐτῷ‘toit[the paradigm]’, if notαὑτῷ‘toitself[as paradigm]’) atTi. 38c1. Inasmuch as the subject of the Platonic title is indeterminate between Eternity and Eternal Beingquaintelligible everlastingness, Iamblichus construesΑΥΤΩΙnot as a mere reflexive but as self-reflexive, withαὑτῷreferring to Timequaintelligible paradigm. In this light, the Platonic lemma grounds the Iamblichean thesis. (shrink)

Neuropsychological research on the neural basis of behaviour generally posits that brain mechanisms will ultimately suffice to explain all psychologically described phenomena. This assumption stems from the idea that the brain is made up entirely of material particles and fields, and that all causal mechanisms relevant to neuroscience can therefore be formulated solely in terms of properties of these elements. Thus, terms having intrinsic mentalistic and/or experiential content (e.g. ‘feeling’, ‘knowing’ and ‘effort’) are not included as primary causal factors. This (...) theoretical restriction is motivated primarily by ideas about the natural world that have been known to be fundamentally incorrect for more than three-quarters of a century. Contemporary basic physical theory differs profoundly from classic physics on the important matter of how the consciousness of human agents enters into the structure of empirical phenomena. The new principles contradict the older idea that local mechanical processes alone can account for the structure of all observed empirical data. Contemporary physical theory brings directly and irreducibly into the overall causal structure certain psychologically described choices made by human agents about how they will act. This key development in basic physical theory is applicable to neuroscience, and it provides neuroscientists and psychologists with an alternative conceptual framework for describing neural processes. Indeed, owing to certain structural features of ion channels critical to synaptic function, contemporary physical theory must in principle be used when analysing human brain dynamics. The new framework, unlike its classic-physics-based predecessor, is erected directly upon, and is compatible with, the prevailing principles of physics. It is able to represent more adequately than classic concepts the neuroplastic mechanisms relevant to the growing number of empirical studies of the capacity of directed attention and mental effort to systematically alter brain function..
