This unique text focuses on ethical puzzles and hypothetical problems to help students at all levels understand and refine their moral principles and see how they apply to various situations. An extensive, thoughtfully written introduction provides the theoretical background and lays out numerous moral puzzle cases that are analyzed and discussed throughout the text. Challenging follow-up articles argue a variety of stances on the ethical puzzles set forth in the introduction.

I consider the question of how literally one can construe the “gauge argument,” which is the canonical means of understanding the putatively central import of local gauge symmetry principles for fundamental physics. As I argue, the gauge argument must be afforded a heuristic reading. Claims to the effect that the argument reflects a deep “logic of nature” must, for numerous reasons I discuss, be taken with a grain of salt.

Specific moral facts seem to be grounded in relevant natural facts, together with relevant moral principles. This picture—according to which moral principles play a role in grounding specific moral facts—is a very natural one, and it may be especially attractive to non-naturalist, robust realists. A recent challenge from Selim Berker threatens this picture, though. Moral principles themselves seem to incorporate grounding claims, and it’s not clear that this can be reconciled with according the principles a grounding (...) role. This chapter responds to Berker’s Challenge, utilizing a grounding pluralism. In particular, it argues that distinguishing between normative and metaphysical grounding is the key to saving the natural picture. It also shows how such a distinction is one that you have a reason to endorse independently of this challenge, as it does important work elsewhere in moral philosophy. (shrink)

The principles and practices of research peer review are described. While the principles are fundamentally generic and apply to peer review across the full spectrum of performing institutions as well as to manuscript/proposal/program peer review, the focus of this paper is peer review of proposed and ongoing programs in federal agencies. The paper describes desireable characteristics and important intangible factors in successful peer review. Also presented is a heuristic protocol for the conduct of successful peer review research evaluations (...) and impact assessments. Problems with peer review are then outlined, followed by examples of peer review of proposed and existing programs in selected federal agencies. Some peer review variants, such as the Science Court, are described, and then research requirements to improve peer review are discussed. (shrink)

This paper opens a critical conversation about the ethics of international bioethics conferencing and proposes principles that commit to being anti-discriminatory, global, and inclusive. We launch this conversation in the Section, Case Study, with a case example involving the International Association of Bioethics’ (IAB’s) selection of Qatar to host the 2024 World Congress of Bioethics. IAB’s choice of Qatar sparked controversy. We believe it also may reveal deeper issues of Islamophobia in bioethics. The Section, Principles for International Bioethics (...) Conferencing, sets forth and defends proposed principles for international bioethics conferencing. The Section, Applying Principles to Site Selection applies the proposed principles to the case example. The Section, Applying Principles Beyond Site Selection addresses other applications of the proposed principles. The Section, Objections responds to objections. We close (in the Section, Conclusion) by calling for a wider discussion of our proposed principles.One-Sentence Capsule Summary: How should bioethicists navigate the ethics of global bioethics conferencing?

Principles of Philosophy was written in Latin by Rene Descartes. Published in 1644, it was intended to replace Aristotle's philosophy and traditional Scholastic Philosophy. This volume contains a letter of the author to the French translator of the Principles of Philosophy serving for a Preface and a letter to the most serene princess, Elizabeth, eldest daughter of Frederick, King of Bohemia, Count Palatine, and Elector of the Sacred Roman Empire. Principes de philosophie, by Claude Picot, under the supervision (...) of Descartes, appeared in 1647 with a letter-preface to Queen Christina of Sweden. (shrink)

I argue for the claim that there are instances of a priori justified belief – in particular, justified belief in moral principles – that are not analytic, i.e., that cannot be explained solely by the understanding we have of their propositions. §1–2 provides the background necessary for understanding this claim: in particular, it distinguishes between two ways a proposition can be analytic, Basis and Constitutive, and provides the general form of a moral principle. §§3–5 consider whether Hume's Law, properly (...) interpreted, can be established by Moore's Open Question Argument, and concludes that it cannot: while Moore's argument – appropriately modified – is effective against the idea that moral judgments are either reductively analyzable or Constitutive-analytic, a different argument is needed to show that they are not Basis-analytic. Such an argument is supplied in §6. §§7–8 conclude by considering how these considerations bear on recent discussions of “alternative normative concepts”, on the epistemology of intuitions, and on the differences between disagreement in moral domains and in other a priori domains such as logic and mathematics.

Contextualist approaches to the Liar Paradox postulate the occurrence of a context shift in the course of the Liar reasoning. In particular, according to the contextualist proposal advanced by Charles Parsons and Michael Glanzberg, the Liar sentence L doesn’t express a true proposition in the initial context of reasoning c, but expresses a true one in a new, richer context c', where more propositions are available for expression. On the further assumption that Liar sentences involve propositional quantifiers whose domains may (...) vary with context, the Liar reasoning is blocked. But why should context shift? We argue that the paradox involves principles of contextualist reflection that explain, by analogy with well-known reflection principles for arithmetic, why context must shift from c to c' in the course of the Liar reasoning. This provides a diagnosis of the Liar Paradox—one that equally applies to two revenge arguments against contextualist approaches, one recently advanced by Andrew Bacon, the other mentioned by Charles Parsons and more recently revived by Cory Juhl.

This paper comments on an article by V.S. Ramachandran and William Hirstein (JCS,1999) in which they purport to be identifying the neurological principles of beauty. I draw attention to the way the problem of beauty is construed in the philosophical literature by Mary Mothersill (1984) and Immanuel Kant (Critique of Judgment). I argue that Ramachandran and Hirsteins' principles do not address the problem of beauty because they do not differentiate between the experience of beauty and other closely related (...) phenomena. I then show how one might address the problem of beauty within the framework that they have adopted. (shrink)

We outline three principles that should guide us in the construction of a theory of canonical quantum gravity: diffeomorphism invariance, implementing the proper dynamics and related constraint algebra, local Lorentz invariance. We illustrate each of them with its role in model calculations in loop quantum gravity.

Knowledge aims to fit the world, and action to change it. In this collection of essays, Onora O'Neill explores the relationship between these concepts and shows that principles are not enough for ethical thought or action: we also need to understand how practical judgement identifies ways of enacting them and of changing the way things are. Both ethical and technical judgement are supported, she contends, by bringing to bear multiple considerations, ranging from ethical principles to real-world constraints, and (...) while we will never find practical algorithms - let alone ethical algorithms - that resolve moral and political issues, good practical judgement can bring abstract principles to bear in situations that call for action. Her essays thus challenge claims that all inquiry must use either the empirical methods of scientific inquiry or the interpretive methods of the humanities. They will appeal to a range of readers in moral and political philosophy. (shrink)

Principles of Ethics, Rosmini's first great work in the field of moral philosophy, looks to the light of reason as the objective basis of moral action. The subjective foundation of such action is the act of will by which we accept what the light of reason places before us. "Acknowledge what you know for what you know it to be" thus becomes the ultimate, self-evident expression of moral obligation. To acknowledge willingly what in fact we know is the essence (...) of morality. Rosmini's moral theory depends upon a thorough examination of the objective nature of knowledge (already carried out in his New Essay), and on a careful analysis of human volition and freedom. Within the system of truth both the simple, straightforward beauty of moral good in the human person and the duplicity of evil become immediately obvious. It is also clear that willing acceptance of moral imperatives does not diminish, but enhances innate human dignity. Moral law, rational law and natural law indicate a single, inviolable source of obligation present to human nature under different aspects. (shrink)

A dispute in epistemology has arisen over whether some class of things epistemic (things known or justified, for example) is closed under some operation involving the notion of what follows deductively from members of this class. Very few philosophers these days believe that if you know that p, and p entails q, then you know that q. But many philosophers think that something weaker holds, for instance that if you know that p, and p entails q, then you are in (...) a position to know that p, or if you know that p and you competently deduce p from q, then you know that q. However there are some considerations tracing back to Wittgenstein’s On Certainty and some early work by Fred Dretske that suggests even these weaker principles are false. (shrink)

In recent years, there has been a substantial amount of work in reverse mathematics concerning natural mathematical principles that are provable from RT, Ramsey's Theorem for Pairs. These principles tend to fall outside of the "big five" systems of reverse mathematics and a complicated picture of subsystems below RT has emerged. In this paper, we answer two open questions concerning these subsystems, specifically that ADS is not equivalent to CAC and that EM is not equivalent to RT.

Should particularists about ethics claim that moral principles are never true? Or should they rather claim that any finite set of principles will not be sufficient to capture ethics? This paper explores and defends the possibility of embracing the second of these claims whilst rejecting the first, a position termed 'principled particularism'. The main argument that particularists present for their position-the argument that holds that any moral conclusion can be superseded by further considerations-is quite compatible with principled particularism; (...) indeed, it is compatible with the idea that every true moral conclusion can be shown to follow deductively from a finite set of premises. Whilst it is true that these premises must contain implicit ceteris paribus clauses, this does not render the arguments trivial. On the contrary, they can do important work in justifying moral conclusions. Finally the approach is briefly applied to the related field of jurisprudence. (shrink)

Concentrating upon applications that are most relevant to modern physics, this valuable book surveys variational principles and examines their relationship to dynamics and quantum theory. Stressing the history and theory of these mathematical concepts rather than the mechanics, the authors provide many insights into the development of quantum mechanics and present much hard-to-find material in a remarkably lucid, compact form. After summarizing the historical background from Pythagoras to Francis Bacon, Professors Yourgrau and Mandelstram cover Fermat's principle of least time, (...) the principle of least action of Maupertuis, development of this principle by Euler and Lagrange, and the equations of Lagrange and Hamilton. Equipped by this thorough preparation to treat variational principles in general, they proceed to derive Hamilton's principle, the Hamilton-Jacobi equation, and Hamilton's canonical equations. An investigation of electrodynamics in Hamiltonian form covers next, followed by a resume of variational principles in classical dynamics. The authors then launch into an analysis of their most significant topics: the relation between variational principles and wave mechanics, and the principles of Feynman and Schwinger in quantum mechanics. Two concluding chapters extend the discussion to hydrodynamics and natural philosophy. Professional physicists, mathematicians, and advanced students with a strong mathematical background will find this stimulating volume invaluable reading. Extremely popular in its hardcover edition, this volume will find even wider appreciation in its first fine inexpensive paperbound edition. (shrink)

Internationally, there is an on-going dialogue about how to professionalize ethics consultation services . Despite these efforts, one aspect of ECS-competence that has received scant attention is the liability of failing to adequately capture all of the relevant moral considerations in an ethics conflict. This failure carries a high price for the least powerful stakeholders in the dispute. When an ECS does not possess a sophisticated dexterity at translating what stakeholders say in a conflict into ethical concepts or principles, (...) it runs the risk of naming one side's claims as morally legitimate and decrying the other's as merely self-serving. The result of this failure is that one side in a dispute is granted significantly more moral weight and authority than the other. The remedy to this problem is that ECSs learn how to expand the diagnostic moral lens they employ in clinical ethics conflicts. (shrink)

Much time has been spent arguing about the soundness of But in the philosophical literature there is no single such principle; there are many harm principles. And many objections pressed against are objections to only some of these principles. The first half of this paper draws a number of distinctions between harm principles. It then argues that each harm principle is compatible with many other principles that impose limits on the law, including but not limited to (...) other harm principles. The second half of the paper applies the lessons of the first to a number of prominent objections to That principle has been accused of a) being underinclusive; b) misrepresenting the reasons why many act-types ought to be legally proscribed; c) permitting lawmakers to treat people as mere means of achieving their ends; and d) being overinclusive. The paper argues that one harm principle survives all four objections. (shrink)

There is general agreement that from the first few months of life, our apprehension of physical objects accords, in some sense, with certain principles. In one philosopher's locution, we are 'perceptually sensitive' to physical principles describing the behavior of objects. But in what does this accordance or sensitivity consist? Are these principles explicitly represented or merely 'implemented'? And what sort of explanation do we accomplish in claiming that our object perception accords with these principles? My main (...) goal here is to suggest answers to these questions. I argue that the object principles are not explicitly represented, first addressing some confusion in the debate about what that means. On the positive side, I conclude that the principles supply a competence account, at Marr's computational level, and that they function like natural constraints in vision. These are among their considerable explanatory benefits - benefits endowed by rules and principles in other cognitive domains as well. Characterizing the explanatory role of the object principles is my main project here, but in pursuing certain sub-goals I am led to other conclusions of interest in their own right. I address an argument that the object principles are explicitly represented which assumes that object perception is substantially thought-like. This provokes a jaunt off the main path which leads to interesting territory: the boundary between thought and perception. I argue that object apprehension is much closer to perception than to thought on the spectrum between the two. (shrink)

The country's leading libertarian scholar sets forth the essential principles for a legal system that best balances individual liberty versus the common good.

Scholars who doubt the existence of general political obligations typically criticize and reject theories of obligation based on individual moral principles, for example, consent, fairness, or a natural duty of justice. Astronger position can result fromcombining different principles in a single theory. I develop a multiprinciple theory of political obligation, based on the principle of fairness, a natural duty of justice, and what I call the “common good” principle. The three principles interact in three main ways: “cumulation,” (...) combining the separate state services that different principles cover; “mutual support,” combining the force of different principles in regard to the same state services; and simple overlap. The resulting theory is able to satisfy the main conditions for an adequate theory of obligation: demonstrating that all or nearly all inhabitants of society have moral requirements to obey the law, and that these extend to the full range of state services.

The thesis that in order to genuinely think about a particular object one must be (in some sense) acquainted with that object has been thoroughly explored since it was put forward by Bertrand Russell. Recently, the thesis has come in for mounting criticism. The aim of this paper is to point out that neither the exploration nor the criticism have been sensitive to the fact that the thesis can be interpreted in two different ways, yielding two different principles of (...) acquaintance. One principle uses the notion of content in distinguishing genuine thinking-about things from a merely derivative kind of thinking-about things. The other principle is quiet about content, focusing instead on a distinction between satisfactional and non-satisfactional means of bringing things into thought. Most work has focused on the first, content-based principle of acquaintance. But criticisms of this principle do not apply straightforwardly to the non-content-based principle. I shall argue that the latter principle merits independent assessment as part of the broader effort to account for genuine thinking about particular objects. In the final section of the paper, I will sketch a roadmap for this assessment. (shrink)

Most of the logics of grounding that have so far been proposed contain grounding axioms, or grounding rules, for the connectives of conjunction, disjunction and negation, but little attention has been dedicated to the implication connective. The present paper aims at repairing this situation by proposing adequate grounding principles for relevant implication. Because of the interaction between negation and implication, new grounding principles concerning negation will also arise.

In this book Kristi A. Olson addresses the question of fair labor income distribution by proposing the solidarity solution, a new test she defines and defends. She takes as her starting point the envy test, discussed by the philosophers Ronald Dworkin and Philippe Van Parijs and by the economists Jan Tinbergen, Hal Varian, Marc Fleurbaey, Duncan Foley, and Serge-Christophe Kolm. According to the envy test, a distribution is fair when no one prefers someone else's circumstances to their own. After rejecting (...) the envy test, Olson distinguishes two types of envy: personal and impersonal. Impersonal envy makes a demand on others; personal envy, in contrast, does not. Using this distinction, Olson argues that fair labor-income bundles must be impersonal envy-free, but need not be personal envy-free. The book concludes by relating the solidarity solution to concrete problems such as the gender wage gap and taxation. (shrink)

In his Kant on Laws, Eric Watkins presents an account of reason on which the principles of specification and continuity are regulative instructions to search for different kinds of the unconditioned. I suggest that we correct Watkins’ account in two ways. First, we need to complete Watkins’ claim to the plurality of the unconditioned: reason aims for three kinds of the unconditioned, associated with the lowest, next and highest concepts. Second, we need to look beyond reason’s search for the (...) unconditioned in order to properly understand the nature of the aim of reason. I argue that we construe reason’s aim as the systematic unity of cognition considered as a whole or, in Kant’s teleological terms, as the realization of an ‘idea’, or a ‘purposive unity’. (shrink)

What are moral principles? The assumption underlying much of the generalism–particularism debate in ethics is that they are (or would be) moral laws: generalizations or some special class thereof, such as explanatory or counterfactual-supporting generalizations. I argue that this law conception of moral principles is mistaken. For moral principles do at least three things that moral laws cannot do, at least not in their own right: explain certain phenomena, provide particular kinds of support for counterfactuals, and ground (...) moral necessities, “necessary connections” between obligating reasons and obligations. Moreover, neither a best-systems theory of moral principles nor any of the competing theories of moral principles proposed by Sean McKeever and Michael Ridge, Pekka Väyrynen, and Mark Lance and Margaret Little could vindicate the law conception of moral principles. I conclude with some brief remarks about what moral principles might be if they are not moral laws. (shrink)

Recent calls have been made to move professional standards to a more principles-based perspective, supposing that emphasizing broad principles would eliminate the legalistic focus that rules may encourage, and accountants’ behavior would be more ethical and uniformly so. However, this supposition has yet to be empirically tested. The AICPA Code of Professional Conduct (Code) provides guidance in both forms: principles and rules. This experiment examines how the form of the Code affects independence judgments in a client acceptance (...) context. We also examine the potential for levels of moral development to influence the effectiveness of the Code.We find that subjects are more likely to consider their independence impaired, and are more likely to reject a questionable audit engagement, when rules-based (principles-based) reasoners are provided with Code rules (principles). Given the popularity of the view that rules-based standards are undesirable, these findings have significant implications for the profession as principles-based ethical standards are discussed.

This paper compares and contrasts three different substantive principles of justice for making health care priority-setting or “rationing” decisions: need principles, maximising principles and egalitarian principles. The principles are compared by tracing out their implications for a hypothetical rationing decision involving four identified patients. This decision has been the subject of an empirical study of public opinion based on small-group discussions, which found that the public seem to support a pluralistic combination of all three kinds (...) of rationing principle. In conclusion, it is suggested that there is room for further work by philosophers and others on the development of a coherent and pluralistic theory of health care rationing which accords with public opinions.

BackgroundDuring the arrival of the COVID-19 pandemic, various professional ethical guidance was issued to (and for) health and social care professionals in England and Wales. Guidance can help to inform and support such professionals and their patients, clients and service users, but a plethora of guidance risked information overload, confusion, and inconsistency. MethodsDuring the early months of the pandemic, we undertook a rapid review, asking: what are the principles adopted by professional ethical guidance in England and Wales for dealing (...) with COVID-19? We undertook thematic content analysis of the 29 documents that met our inclusion criteria.ResultsThe 29 documents captured 13 overlapping principles: respect, fairness, minimising harm, reciprocity, proportionality, flexibility, working together, inclusiveness, communication, transparency, reasonableness, responsibility, and accountability.ConclusionsWe intend this attempt to collate and outline the prominent principles to be helpful, particularly, for healthcare practice during the COVID-19 pandemic and, hopefully, for future pandemic planning. We also offer some reflections on the guidance and the principles therein. After describing the principles, we reflect on some of the similarities and differences in the guidance, and the challenges associated not only with the specific guidance reviewed, but also with the nature and import of “professional ethical guidance”.

© 2016 Informa UK Limited, trading as Taylor & Francis Group. Within the umbrella of equal recognition, several principles of linguistic justice can be distinguished. A first, the per-capita principle, mandates prorating language recognition based on a per-capita distribution. A second, the equal-services principle, prescribes upholding the official languages as the languages in which the state speaks and in which public services are provided, irrespective of changing numbers of speakers. Alan Patten defends the prorated per-capita principle. I argue for (...) the equal-services principle, which practically will often amount to a form of linguistic maximin: the more vulnerable the language, the more numerous the resources. (shrink)

This paper provides an axiomatic analysis of sufficientarian social evaluation. Sufficientarianism has emerged as an increasingly important notion of distributive justice. We propose a class of principles that we label generalized critical-level sufficientarian orderings. The distinguishing feature of our new class is that its members exhibit constant critical levels of well-being that are allowed to differ from the threshold of sufficiency. Our basic axiom assigns priority to those below the threshold, a property that is shared by numerous other sufficientarian (...) approaches. When combined with the well-known strong Pareto principle and the assumption that there be a constant critical level, the axiom implies that the critical level cannot be below the threshold. The main results of the paper are characterizations of our new class and an important subclass. As a final observation, we identify the generalized critical-level sufficientarian orderings that permit us to avoid the repugnant conclusion and the sadistic conclusion, which are known as two fundamental challenges in population ethics.

Cerebral organoid models in-of-themselves are considered as an alternative to research animal models. But their developmental and biological limitations currently inhibit the probability that organoids can fully replace animal models. Furthermore, these organoid limitations have, somewhat ironically, brought researchers back to the animal model via xenotransplantation, thus creating hybrids and chimeras. In addition to attempting to study and overcome cerebral organoid limitations, transplanting cerebral organoids into animal models brings an opportunity to observe behavioral changes in the animal itself. Traditional animal (...) ethics frameworks, such as the well-known three Rs (reduce, refine, and replace), have previously addressed chimeras and xenotransplantation of tissue. But these frameworks have yet to completely assess the neural-chimeric possibilities. And while the three Rs framework was a historical landmark in animal ethics, there are identifiable gaps in the framework that require attention. The authors propose to utilize an expanded three Rs framework initially developed by David DeGrazia and Tom L. Beauchamp, known as the Six Principles (6Ps). This framework aims to expand upon the three Rs, fill in the gaps, and be a practical means for assessing animal ethical issues like that of neural-chimeras and cerebral organoid xenotransplantation. The scope of this 6Ps application will focus on two separate but recent studies, which were published in 2019 and 2020. First, they consider a study wherein cerebral organoids were grown from donors with Down syndrome and from neurotypical donors. After these organoids were grown and studied, they were then surgically implanted into mouse models to observe the physiological effects and any behavioral change in the chimera. Second, they consider a separate study wherein neurotypical human embryonic stem cell-derived cerebral organoids were grown and transplanted into mouse and macaque models. The aim was to observe if such a transplantation method would contribute to therapies for brain injury or stroke. The authors place both studies under the lens of the 6Ps framework, assess the relevant contexts of each case, and provide relevant normative conclusions. In this way, they demonstrate how the 6Ps could be applied in future cases of neural-chimeras and cerebral organoid xenotransplantation. (shrink)

Although written primarily for medical research, the Belmont principles have permeated clinical medicine as well. In fact, they are part of a broad cultural shift that has dramatically reworked the relationship between doctor and patient. In the early 1950s, medicine was about making the patient better and maintaining optimism when the patient could not get better. By the 1990s, medicine was about the treatment of specific physiological systems, as directed by the patient, but as limited by the society's concern (...) for justice. (shrink)

Lists of species underpin many fields of human endeavour, but there are currently no universally accepted principles for deciding which biological species should be accepted when there are alternative taxonomic treatments (and, by extension, which scientific names should be applied to those species). As improvements in information technology make it easier to communicate, access, and aggregate biodiversity information, there is a need for a framework that helps taxonomists and the users of taxonomy decide which taxa and names should be (...) used by society whilst continuing to encourage taxonomic research that leads to new species discoveries, new knowledge of species relationships, and the refinement of existing species concepts. Here, we present 10 principles that can underpin such a governance framework, namely (i) the species list must be based on science and free from nontaxonomic considerations and interference, (ii) governance of the species list must aim for community support and use, (iii) all decisions about list composition must be transparent, (iv) the governance of validated lists of species is separate from the governance of the names of taxa, (v) governance of lists of accepted species must not constrain academic freedom, (vi) the set of criteria considered sufficient to recognise species boundaries may appropriately vary between different taxonomic groups but should be consistent when possible, (vii) a global list must balance conflicting needs for currency and stability by having archived versions, (viii) contributors need appropriate recognition, (ix) list content should be traceable, and (x) a global listing process needs both to encompass global diversity and to accommodate local knowledge of that diversity. We conclude by outlining issues that must be resolved if such a system of taxonomic list governance and a unified list of accepted scientific names generated are to be universally adopted. (shrink)

In recent years, several political theorists have argued that reasonable principles of justice are practice-dependent. In this paper it is suggested that we can distinguish between at least two main models for doing practice-dependent theorizing about justice, interpretivism and constructivism, and that they can be understood as based in two different conceptions of practices. It is then argued that the reliance on the notion of participants that characterizes interpretivism disables this approach from adequately addressing certain matters of justice and (...) that a better way of developing the idea of practice-dependence can be found in a constructivism that starts from the Rawlsian idea of overlapping consensus, but which shifts the focus of that approach from societies to a more open-ended category of domains, and which understands the parties to a possible overlapping consensus as stakeholders in a certain set of interconnected practices.

Discussions of free will have frequently centered on principles concerning ability, control, unavoidability and other practical modalities. Some assert the closure of the latter over various propositional operations and relations, for example, that the consequences of what is beyond one's control are themselves beyond one's control.1 This principle has been featured in the unavoidability argument for incompatibilism: if everything we do is determined by factors which are not under our control, then, by the principle, we are unable to act (...) and choose other than we actually did. A second family of principles concerns the fixity of the past and the laws of nature. If no one is able to alter the past or violate the laws it seems but a small step to conclude that no one can do anything such that if they did it then the past would be altered or the laws violated. Accordingly, if an agent's performing an act is necessitated by the past and laws, then the agent is unable to refrain from that act at that time. Generalizing, determinism precludes anyone from doing anything other than what he or she did.2. (shrink)

The nature of attention is one of the oldest and most central problems in psychology. A huge amount of research has been produced on this subject in the last half century, especially on attention in the visual modality, but a general explanation has remained elusive. Many still view attention research as a field that is fundamentally fragmented. This book takes a different perspective and presents a unified theory of visual attention: the TVA model. The TVA model explains the many aspects (...) of visual attention by just two mechanisms for selection of information: filtering and pigeonholing. These mechanisms are described in a set of simple equations, which allow TVA to mathematically model a large number of classical results in the attention literature. The theory explains psychological and neuroscientific findings by the same equations; TVA is a complete theory of visual attention, linking mind and brain. Aimed at advanced students and professional researchers, Principles of Visual Attention contains a detailed review of the most important research done on attention in vision, spanning cognitive psychology, brain imaging, patient studies, and recordings from single cells in the visual cortex. The book explains the TVA model and shows how it accounts for attentional effects observed across all the research areas described. Principles of Visual Attention offers a uniquely integrated view on a central topic in cognitive neuroscience. (shrink)
