We introduce a realist, unextravagant interpretation of quantum theory that builds on the existing physical structure of the theory and allows experiments to have definite outcomes but leaves the theory’s basic dynamical content essentially intact. Much as classical systems have specific states that evolve along definite trajectories through configuration spaces, the traditional formulation of quantum theory permits assuming that closed quantum systems have specific states that evolve unitarily along definite trajectories through Hilbert spaces, and our interpretation extends this intuitive picture (...) of states and Hilbert-space trajectories to the more realistic case of open quantum systems despite the generic development of entanglement. We provide independent justification for the partial-trace operation for density matrices, reformulate wave-function collapse in terms of an underlying interpolating dynamics, derive the Born rule from deeper principles, resolve several open questions regarding ontological stability and dynamics, address a number of familiar no-go theorems, and argue that our interpretation is ultimately compatible with Lorentz invariance. Along the way, we also investigate a number of unexplored features of quantum theory, including an interesting geometrical structure—which we call subsystem space—that we believe merits further study. We conclude with a summary, a list of criteria for future work on quantum foundations, and further research directions. We include an appendix that briefly reviews the traditional Copenhagen interpretation and the measurement problem of quantum theory, as well as the instrumentalist approach and a collection of foundational theorems not otherwise discussed in the main text.

Any realist interpretation of quantum theory must grapple with the measurement problem and the status of state-vector collapse. In a no-collapse approach, measurement is typically modeled as a dynamical process involving decoherence. We describe how the minimal modal interpretation closes a gap in this dynamical description, leading to a complete and consistent resolution to the measurement problem and an effective form of state collapse. Our interpretation also provides insight into the indivisible nature of measurement—the fact that you can't stop a (...) measurement part-way through and uncover the underlying 'ontic' dynamics of the system in question. Having discussed the hidden dynamics of a system's ontic state during measurement, we turn to more general forms of open-system dynamics and explore the extent to which the details of the underlying ontic behavior of a system can be described. We construct a space of ontic trajectories and describe obstructions to defining a probability measure on this space. (shrink)

As early as 1962, Jürgen Habermas was convinced that Karl Marx’s theoretical attempt to ‘turn Hegel the right side up’ had resulted in a one-sided embrace of revolution and a perilous rejection of legality and rights. Habermas would restate these remarks thirty years later in Between Facts and Norms, noting that the collapse of state socialism, with its characteristic disdain for legality and rights, culminated in the discrediting of revolutionary Marxism. This article revisits Habermas’s theoretical dichotomy between revolution and legality (...) in view of his ambivalent relationship to ‘Marx’s spectre’ and shows its significance for Habermas’s ongoing debate with Wolfgang Streeck concerning the tension between democracy and capitalism. Using textual evidence from Marx’s neglected journalistic writings before, during, and after the 1848 revolutions, the article offers a competing perspective of Marx’s views on legality and rights at a time when their respective fates were critically at stake. A careful reconsideration of Marx’s reflections and a confrontation with his spectre offers Habermas fruitful resources for responding to Streeck’s critique and for reviving the project of ‘radical reformism’ at a time when the liberal constitutional order finds itself under attack.

The article is the study of some aspects of the methodology of scientific knowledge that F. Bacon addressed in his treatise “New Organon” (1620) and in other works in one way or another related to his work on the project of the Instauratio Magna Scientiarum. The article focuses on the following three questions: Bacon’s attitude to Aristotle’s legacy, the context of Bacon’s doctrine of idols and the reasons for the English philosopher to choose a fragmented (aphoristic) form of presentation of (...) his ideas in the “New Organon” and in some other works. Based on an analysis of Bacon’s works related to the above project, it was shown that his statements about Aristotle and his philosophy were differentiated depending on whether the corresponding text was intended for printing or served as a working draft. In the latter case, the estimates of Aristotle by Bacon were more stringent. Baconian criticism of Aristotelianism was formed in the context of the development by the English philosopher of the doctrine of the idols of knowledge. The article shows that developing this doctrine, Bacon proceeded from the idea of mass insanity of the human race (insania publica), which has ancient roots and was shared by a number of contemporaries of F. Bacon. At the same time, the latter considered Aristotle as the creator of “a kind of art of insanity (artemque quondam insaniae componere)”. As a cure for “insania universalis”, Bacon proposed a new method (the “new organon”) of cognition, and the presentation of his ideas in the form of separate, but conceptually related aphorisms, as a way of activating the reader’s thought process.

Most people believe that there are limits to the sacrifices that morality can demand. Although it would often be meritorious, we are not, in fact, morally required to do all that we can to promote overall good. What's more, most people also believe that certain types of acts are simply forbidden, morally off limits, even when necessary for promoting the overall good. In this provocative analysis Kagan maintains that despite the intuitive appeal of these views, they cannot be adequately (...) defended. In criticizing arguments for limited moral requirements as well as those for unconditionally prohibited acts, Kagan offers a sustained attack on two of the most basic features of ordinary common sense morality.

There is one thing we can be sure of: we are all going to die. But once we accept that fact, the questions begin. In this thought-provoking book, philosophy professor Shelly Kagan examines the myriad questions that arise when we confront the meaning of mortality. Do we have reason to believe in the existence of immortal souls? Or should we accept an account according to which people are just material objects, nothing more? Can we make sense of the idea (...) of surviving the death of one’s body? If I won’t exist after I die, can death truly be _bad_ for me? Would immortality be desirable? Is fear of death appropriate? Is suicide ever justified? How should I _live_ in the face of death? Written in an informal and conversational style, this stimulating and provocative book challenges many widely held views about death, as it invites the reader to take a fresh look at one of the central features of the human condition—the fact that we will die.

Kagan ponders a series of important nodes of debate while challenging us to examine what we know and why we know it. Most critically he presents an elegant argument for functions of mind that cannot be replaced with sentences about brains while acknowledging that mind emerges from brain activity. He relies on the evidence to argue that thoughts and emotions are distinct from their biological and genetic bases. In separate chapters he deals with the meaning of words, kinds of (...) knowing, the powerful influence of social class, the functions of education, emotion, morality, and other issues. And without fail he sheds light on these ideas while remaining honest to their complexity." -- Publisher's description. (shrink)

Shelly Kagan argues for a hierarchical position in animal ethics where people count more than animals do, and some animals count more than others. In arguing for his account of morality, Kagan sets out what needs to be done to establish our obligations toward animals and to fulfil our duties to them.

What are the limits of well-being? This question nicely captures one of the central debates concerning the nature of the individual human good. For rival theories differ as to what sort of facts directly constitute a person's being well-off. On some views, well-being is limited to the presence of pleasure and the absence of pain. But other views push the boundaries of well-being beyond this, so that it encompasses a variety of mental states, not merely pleasure alone. Some theories then (...) draw the line here, limiting well-being to the presence of the appropriately broadened set of mental states. But still others extend the limits of well-being even further, so that it is constituted in part by facts that are not themselves mental states at all; on such views, well-being is partly constituted by states of affairs that are “external” to the individual's experiences. In this essay, I want to explore some of this debate by focusing on a particular stretch of the dialectic. That is, I want to think hard about a particular connected series of arguments and counterarguments. These arguments – or, at least, the concerns they seek to express – emerge naturally in the give and take of philosophical discussion. Together they make up a rather simple story, whose plot, in very rough terms, is this: first there is an attempt to push the limits of well-being outward, moving from a narrow to a broader conception; then comes the claim that the resulting notion is too broad, and so we must retreat to a narrower conception after all.

According to the dominant philosophical tradition, intrinsic value must depend solely upon intrinsic properties. By appealing to various examples, however, I argue that we should at least leave open the possibility that in some cases intrinsic value may be based in part on relational properties. Indeed, I argue that we should even be open to the possibility that an object''s intrinsic value may sometimes depend (in part) on its instrumental value. If this is right, of course, then the traditional contrast (...) between intrinsic value and instrumental value is mistaken. (shrink)

Conditionals whose antecedent and consequent are not somehow internally connected tend to strike us as odd. The received doctrine is that this felt oddness is to be explained pragmatically. Exactly how the pragmatic explanation is supposed to go has remained elusive, however. This paper discusses recent philosophical and psychological work that attempts to account semantically for the apparent oddness of conditionals lacking an internal connection between their parts.

Anyone who reflects on the way we go about arguing for or against moral claims is likely to be struck by the central importance we give to thinking about cases. Intuitive reactions to cases—real or imagined—are carefully noted, and then appealed to as providing reason to accept various claims. When trying on a general moral theory for size, for example, we typically get a feel for its overall plausibility by considering its implications in a range of cases. Similarly, when we (...) try to refine the statement of a principle meant to cover a fairly specific part of morality, we guide ourselves by testing the various possible revisions against a carefully constructed set of cases. And when arguing against a claim, we take ourselves to have shown something significant if we can find an intuitively compelling counterexample, and such counterexamples almost always take the form of a description of one or another case where the implications of the claim in question seem implausible. Even when we find ourselves faced with a case where we have no immediate and clear reaction, or where we have such a reaction, but others don't share it and we need to persuade them, in what is probably the most common way of trying to make progress we consider various analogies and disanalogies; that is to say, we appeal to still other cases, and by seeing what we want to say there, we discover what it is plausible to say in the original case. In these and other ways, then, the appeal to cases plays a central and ubiquitous role in our moral thinking. (shrink)

This paper aims to contribute to our understanding of the notion of coherence by explicating in probabilistic terms, step by step, what seem to be our most basic intuitions about that notion, to wit, that coherence is a matter of hanging or fitting together, and that coherence is a matter of degree. A qualitative theory of coherence will serve as a stepping stone to formulate a set of quantitative measures of coherence, each of which seems to capture well the aforementioned (...) intuitions. Subsequently it will be argued that one of those measures does better than the others in light of some more specific intuitions about coherence. This measure will be defended against two seemingly obvious objections. (shrink)

A paper on how to adapt your probabilisitc beliefs when learning a conditional.

Mindwandering is associated with both positive and negative outcomes. Among the latter, negative mood and negative cognitions have been reported. However, the underlying mechanisms linking mindwandering to negative mood and cognition are still unclear. We hypothesized that MW could either directly enhance negative thinking or indirectly heighten the accessibility of negative thoughts. In an undergraduate sample we measured emotional thoughts during the Sustained Attention on Response Task which induces MW, and accessibility of negative cognitions by means of the Scrambled Sentences (...) Task after the task. We also measured depressive symptoms and rumination. Results show that in individuals with elevated levels of depressive symptoms MW during SART predicts higher accessibility of negative thoughts after the task, rather than negative thinking during the task. These findings contribute to our understanding of the underlying mechanisms of MW and provide insight into the relationship between task-involvement and affect. (shrink)

Peter Singer famously argued in Animal Liberation that almost all of us are speciesists, unjustifiably favoring the interests of humans over the similar interests of other animals. Although I long found that charge compelling, I now find myself having doubts. This article starts by trying to get clear about the nature of speciesism, and then argues that Singer's attempt to show that speciesism is a mere prejudice is unsuccessful. I also argue that most of us are not actually speciesists at (...) all, but rather accept a view I call modal personism. Although I am not confident that modal personism can be adequately defended, it is, at the very least, a philosophical view worthy of further consideration. (shrink)

The possibility of formal representation of Aristotle’s discussion about singular predication in Categories 10, 13b27-35 is investigated through three symbolic idioms: the first-order language with identity, with and without definitive description, and through the languages of free logics. I show that such representations are not fully adequate. According to the first option, we are committing Aristotle with some (meta)logical implications he is not willing to accept. According to the second option, we are burdening Aristotle with Russell’s theory of names. Finally, (...) the third option leaves us with the assumption that ‘exist(s)’ could be represented with a predicate. This assumption, however, Aristotle emphatically rejects. (shrink)

In 1959 C. P. Snow delivered his now-famous Rede Lecture, 'The Two Cultures,' a reflection on the academy based on the premise that intellectual life was divided into two cultures: the arts and humanities on one side and science on the other. Since then, a third culture, generally termed 'social science' and comprised of fields such as sociology, political science, economics, and psychology, has emerged. Jerome Kagan's book describes the assumptions, vocabulary, and contributions of each of these cultures and (...) argues that the meanings of many of the concepts used by each culture are unique to it and do not apply to the others because the source of evidence for the term is special. The text summarizes the contributions of the social sciences and humanities to our understanding of human nature and questions the popular belief that biological processes are the main determinant of variation in human behavior.

Typically, discussions of well-being focus almost exclusively on the positive aspects of well-being, those elements which directly contribute to a life going well, or better. It is generally assumed, without comment, that there is no need to explicitly discuss ill-being as well—that is, the part of the theory of well-being that specifies the elements which directly contribute to a life going badly, or less well—since (or so it is thought) this raises no special difficulties or problems. But this common assumption (...) is a mistake, since it is far from obvious how to extend even familiar theories of well-being so as to explicitly cover ill-being as well. This paper acts as an introduction to ill-being, noting some of the interesting and overlooked problems ill-being raises for qualitative hedonism, preference theory, and objective list theories. Particular attention is paid, by way of illustration, to the claim that knowledge is an objective good. Assuming this is so, what exactly is the opposite of knowledge, the objective bad which lowers one’s well-being in the same way that knowledge raises it? (shrink)

The purpose of this paper is to present the theoretical and philosophical assumptions of the Nursing Manifesto , written by three activist scholars whose objective was to promote emancipatory nursing research, practice, and education within the dialogue and praxis of social justice. Inspired by discussions with a number of nurse philosophers at the 2008 Knowledge Conference in Boston, two of the original Manifesto authors and two colleagues discussed the need to explicate emancipatory knowing as it emerged from the Manifesto . (...) Our analysis yielded an epistemological framework based on liberation principles to advance praxis in the discipline of nursing. This paper adds to what is already known on this topic, as there is not an explicit contribution to the literature of this specific Manifesto , its significance, and utility for the discipline. While each of us have written on emancipatory knowing and social justice in a variety of works, it is in this article that we identify, as a unit of knowledge production and as a direction towards praxis, a set of critical values that arose from the emancipatory conscience-ness and intention seen in the framework of the Nursing Manifesto.

The sequent system LDJ is formulated using the same connectives as Gentzen's intuitionistic sequent system LJ, but is dual in the following sense: (i) whereas LJ is singular in the consequent, LDJ is singular in the antecedent; (ii) whereas LJ has the same sentential counter-theorems as classical LK but not the same theorems, LDJ has the same sentential theorems as LK but not the same counter-theorems. In particular, LDJ does not reject all contradictions and is accordingly paraconsistent. To obtain a (...) more precise mapping, both LJ and LDJ are extended by adding a "pseudo-difference" operator which is the dual of intuitionistic implication. Cut-elimination and decidability are proved for the extended systems and , and a simply consistent but -inconsistent Set Theory with Unrestricted Comprehension Schema based on LDJ is sketched.

Van Fraassen (1989) argues that Inference to the Best Explanation is incoherent in the sense that adopting it as a rule for belief change will make one susceptible to a dynamic Dutch book. The present paper argues against this. A strategy is described that allows us to infer to the best explanation free of charge.
