This paper reviews the fate of the central ideas behind the complementary learning systems (CLS) framework as originally articulated in McClelland, McNaughton, and O’Reilly (1995). This framework explains why the brain requires two differentially specialized learning and memory systems, and it nicely specifies their central properties (i.e., the hippocampus as a sparse, pattern-separated system for rapidly learning episodic memories, and the neocortex as a distributed, overlapping system for gradually integrating across episodes to extract latent semantic structure). We review the (...) application of the CLS framework to a range of important topics, including the following: the basic neural processes of hippocampal memory encoding and recall, conjunctive encoding, human recognition memory, consolidation of initial hippocampal learning in cortex, dynamic modulation of encoding versus recall, and the synergistic interactions between hippocampus and neocortex. Overall, the CLS framework remains a vital theoretical force in the field, with the empirical data over the past 15 years generally confirming its key principles. (shrink)

The chapter introduces and characterizes the notion of fittingness. It charts the history of the relation and its relevance to contemporary debates in normative and metanormative philosophy and proceeds to survey issues to do with fittingness covered in the volume’s chapters, including the nature and epistemology of fittingness, the relations between fittingness and reasons, the normativity of fittingness, fittingness and value theory, and the role of fittingness in theorizing about responsibility. The chapter concludes with a brief discussion of issues to (...) do with fittingness that aren’t covered extensively by the volume’s chapters in order to indicate avenues for further research.

Stephen Kearns and Daniel Star have made the following interesting proposal concerning the relation between practical reasons and evidence : Necessarily: A fact F is a reason for you to φ iff F is evidence that you ought to φ We're not sure about this. Although moving from left to right might be OK, the converse is problematic. For example, the fact that your reliable friend told you that you have overriding moral reason to φ is ….

This paper comprises three sections. First, we offer a traditional defence of deontology, in the manner of, for example, W.D. Ross (1965). The leading idea of such a defence is that the right is independent of the good. Second, we modify the now standard account of the distinction, in terms of the agent-relative/agentneutral divide, between deontology and consequentialism. (This modification is necessary if indirect consequentialism is to count as a form of consequentialism.) Third, we challenge a value-based defence of deontology (...) proposed by Quinn (1993), Kamm (1989, 1992), and Nagel (1995). (shrink)

This study looks at the relationship between the two thinkers and demonstrates the viable alternative to Hobbes' orthodoxy that can be found in Kant's political writings. It also shows how Kant anticipated the development of a world-wide political order.

In any probabilistic theory, we say that a bipartite state ω on a composite system AB steers its marginal state ω B if, for any decomposition of ω B as a mixture ω B =∑ i p i β i of states β i on B, there exists an observable {a i } on A such that the conditional states $\omega_{B|a_{i}}$ are exactly the states β i . This is always so for pure bipartite states in quantum mechanics, a fact (...) first observed by Schrödinger in 1935. Here, we show that, for weakly self-dual state spaces (those isomorphic, but perhaps not canonically isomorphic, to their dual spaces), the assumption that every state of a system A is steered by some bipartite state of a composite AA consisting of two copies of A, amounts to the homogeneity of the state cone. If the state space is actually self-dual, and not just weakly so, this implies (via the Koecher-Vinberg Theorem) that it is the self-adjoint part of a formally real Jordan algebra, and hence, quite close to being quantum mechanical.

Using a result of H. Hanche-Olsen, we show that (subject to fairly natural constraints on what constitutes a system, and on what constitutes a composite system), orthodox finite-dimensional complex quantum mechanics with superselection rules is the only non-signaling probabilistic theory in which (i) individual systems are Jordan algebras (equivalently, their cones of unnormalized states are homogeneous and self-dual), (ii) composites are locally tomographic (meaning that states are determined by the joint probabilities they assign to measurement outcomes on the component systems) (...) and (iii) at least one system has the structure of a qubit. Using this result, we also characterize finite dimensional quantum theory among probabilistic theories having the structure of a dagger-monoidal category. (shrink)

In this volume, thirteen distinguished contributors from the United States, Canada, Britain, and Germany cast light on important aspects of Kant's liberal thinking.

significant role for accomplishment thereby admits a ‘Trojan Horse’ (267).1 To abandon hedonism in favour of a conception of well-being that incorporates achievement is to take the first step down a slippery slope toward the collapse of the other two pillars of utilitarian morality: welfarism and consequentialism. We shall argue that Crisp’s arguments do not support these conclusions. We begin with welfarism. Crisp defines it thus: ‘Well-being is the only value. Everything good must be good for some being or beings’ (...) (264). The first part of this definition is potentially misleading, since it makes it sound as if welfarism adopts a monistic account of value, in which well-being is the only good thing. But well-being, as Crisp notes, when discussing hedonism, is best understood as consisting in a balance of good things over bad in one’s life. So understood, welfarism is silent on the issue of what things are good; it places a structural restriction on what kinds of things can be good: they must be things that are good for beings. It is a separate task to supply the content to fit this structure by determining what things are good, and welfarists differ in their answers: hedonists traditionally assert that pleasure alone is good; others add further items such as knowledge and virtue. Why is the thought that a person’s well-being depends importantly on what they accomplish a threat to welfarism? An accomplishment is judged both by its outcome or product and by the manner of the performance itself. But an activity or outcome is only an achievement if it is worthwhile, and whether it is worthwhile will depend on whether it exhibits what Crisp asserts to be ‘non-welfarist values’ (266), such as beauty, grace, importance, or style - excellences which welfarism, in Crisp’s view, cannot accommodate because they cannot be ‘cashed out in welfarist terms’, or ‘reduced to the value of well-being’ (266). Here Crisp rests his case, but it is worth trying to get clearer about the difficulties in order to see if the welfarist can meet them.. (shrink)

This chapter analyses Butler's ethical theories, which are found primarily in Fifteen Sermons and A Dissertation of the Nature of Virtue. It covers his notions of superiority and authority, the supremacy of conscience, virtue, benevolence, and self-love.

The concept of an infinite game played on a finite graph is perhaps novel in the context of an rather extensive recent literature in which infinite games are generally played on an infinite game tree. We claim two advantages for our model, which is admittedly more restrictive. First, our games have a more apparent resemblance to ordinary parlor games in spite of their infinite duration. Second, by distinguishing those nodes of the graph that determine the winning and losing of the (...) game , we are able to offer a complexity analysis that is useful in computer science applications.

Richard Swinburne (in his "Responsibility and Atonement") argues for a sacrificial version of the Atonement, in which the individual penitent offers the life of Christ to God in (partial) reparation for his sins. I argue that any version of this account is both conceptually incoherent and morally unsatisfying and offer in its place a version of the exemplary theory of the Atonement which, I claim, meets the conditions he lays down for any satisfactory account.

Quantum information science is a source of task-related axioms whose consequences can be explored in general settings encompassing quantum mechanics, classical theory, and more. Quantum states are compendia of probabilities for the outcomes of possible operations we may perform on a system: ''operational states.'' I discuss general frameworks for ''operational theories'' (sets of possible operational states of a system), in which convexity plays key role. The main technical content of the paper is in a theorem that any such theory naturally (...) gives rise to a ''weak effect algebra'' when outcomes having the same probability in all states are identified and in the introduction of a notion of ''operation algebra'' that also takes account of sequential and conditional operations. Such frameworks are appropriate for investigating what things look like from an ''inside view,'' i.e., for describing perspectival information that one subsystem of the world can have about another. Understanding how such views can combine, and whether an overall ''geometric'' picture (''outside view'') coordinating them all can be had, even if this picture is very different in structure from the perspectives within it, is the key to whether we may be able to achieve a unified, ''objective'' physical view in which quantum mechanics is the appropriate description for certain perspectives, or whether quantum mechanics is truly telling us we must go beyond this ''geometric'' conception of physics.

This chapter proposes a novel form of deontology that, while it contrasts with consequentialism in defending duties of special relationship and options, is allied with consequentialism in denying that there are moral constraints. It devotes considerable attention to distinguishing between various consequentialist doctrines, and the distinction between them and deontology. The distinction between agent-relativity and agent-neutrality plays a crucial role here. It also discusses and rejects contractualism. The same applies to particularism in its most radical form: despite the sympathy for (...) the particularist’s skepticism concerning strict moral principles, it is argued that there are principles of a weaker, Rossian form.

Scanlon suggests a buck-passing account of goodness. To say that something is good is not to give a reason to, say, favour it; rather it is to say that there are such reasons. When it comes to wrongness, however, Scanlon rejects a buck-passing account: to say that j ing is wrong is, on his view, to give a sufficient moral reason not to j. Philip Stratton-Lake 2003 argues that Scanlon can evade a redundancy objection against his (Scanlon’s) view of wrongness (...) by adopting a buck-passing account of wrongness. We argue that this manoeuvre does not succeed. Scanlon’s notion of wrongness rests on the idea of a reasonably rejectable principle. As Stratton-Lake points out, Scanlon offers two accounts, one in terms of permission, the other in terms of proscription. The permission account is tricky to formulate. Scanlon’s account (quoted in Stratton-Lake 2003: 71) might suggest any of the following four formulations (where the principles in question are principles ‘governing how one may act’ (Scanlon..

In the categorical approach to the foundations of quantum theory, one begins with a symmetric monoidal category, the objects of which represent physical systems, and the morphisms of which represent physical processes. Usually, this category is taken to be at least compact closed, and more often, dagger compact, enforcing a certain self-duality, whereby preparation processes (roughly, states) are interconvertible with processes of registration (roughly, measurement outcomes). This is in contrast to the more concrete “operational” approach, in which the states and (...) measurement outcomes associated with a physical system are represented in terms of what we here call a convex operational model: a certain dual pair of ordered linear spaces–generally, not isomorphic to one another. On the other hand, state spaces for which there is such an isomorphism, which we term weakly self-dual, play an important role in reconstructions of various quantum-information theoretic protocols, including teleportation and ensemble steering. In this paper, we characterize compact closure of symmetric monoidal categories of convex operational models in two ways: as a statement about the existence of teleportation protocols, and as the principle that every process allowed by that theory can be realized as an instance of a remote evaluation protocol—hence, as a form of classical probabilistic conditioning. In a large class of cases, which includes both the classical and quantum cases, the relevant compact closed categories are degenerate, in the weak sense that every object is its own dual. We characterize the dagger-compactness of such a category (with respect to the natural adjoint) in terms of the existence, for each system, of a symmetric bipartite state, the associated conditioning map of which is an isomorphism.

Let L be a computable vocabulary, let X_L be the space of L-structures with universe ω and let f:2^\omega \rightarrow X_L be a hyperarithmetic function such that for all x,y \in 2^\omega, if x \equiv _h y then f(x) \cong f(y). One of the following two properties must hold. (1) The Scott rank of f(0) is \omega _1^{CK} + 1. (2) For all x \in 2^\omega, f(x) \cong f(0).

We generalize two concepts from special cases of Polish group actions to the general case. The two concepts are elementary embeddability, from model theory, and analytic sets, from the usual descriptive set theory.

This paper provides an outline of Kant's ideas on international right showing how they derive from his general view of law and showing how they relate to his cosmopolitan ideal of hospitality, his views on colonialism and the vexed issue of intervention in the internal politics of other states. It can be shown – based on his ideal of hospitality and good state practice – that Kant is reluctant to recommend intervention by advanced states in the affairs of other states (...) and societies even where those societies have not attained a settled, civil status. This is not to imply that we should be indifferent to the situation of other peoples, but rather that we should encourage them to find their own way to a more advanced condition. We can best encourage them by setting and abiding by rigorous standards of law both domestically and internationally that create the possibility of a wholly legally regulated international system.War should be regarded as neither a desirable nor, ultimately, a legitimate means of pursuing foreign policy.

D. Dieks has proposed a semantical rule which he claims yields a realistic interpretation of the formalism of quantum mechanics without the projection postulate. I argue that his proposal is unacceptable because it violates a natural requirement of psychophysical parallelism. His "semantical rule" is not an acceptable interpretive rule because it does not identify structures in the theory with structures in our experience, but postulates a merely probabilistic relationship between the two. Dieks' interpretation is contrasted with Everett's relative state interpretation, (...) which attempts the same task but respects psychophysical parallelism. (shrink)
