I start with a critical discussion of some attempts to ground epistemic normativity in curiosity. Then I develop three positive proposals. The first of these proposals is more or less purely philosophical; the second two reside at the interdisciplinary borderline between philosophy and psychology. The proposals are independent and rooted in different literatures. Readers uninterested in the first proposal (and the critical discussion preceding it) may nonetheless be interested in the second two proposals, and vice versa. -/- The proposals are (...) as follows. First I argue that, among several ways in which the notion of curiosity might be used to delineate significant truths from trivial ones, a particular way is the most promising. Second, I argue that curiosity has some underappreciated epistemic roles involving memory. Third, I argue that curiosity has some underappreciated epistemic roles involving coherence. (shrink)

'Holographic' relations between theories have become a main theme in quantum gravity research. These relations entail that a theory without gravity is equivalent to a gravitational theory with an extra spatial dimension. The idea of holography was first proposed in 1993 by Gerard 't Hooft on the basis of his studies of evaporating black holes. Soon afterwards the holographic 'AdS/CFT' duality was introduced, which since has been heavily studied in the string theory community and beyond. Recently, Erik Verlinde has proposed (...) that even Newton's law of gravitation can be related holographically to the thermodynamics of information on screens. We discuss inter-theoretical relations in these scenarios: what is the status of the holographic relation in them and in what sense is gravity, or spacetime, emergent? (shrink)

Dennis Schulting offers a thoroughgoing, analytic account of the first half of the Transcendental Deduction of the Categories in the B-edition of Kant's Critique of Pure Reason that is different from existing interpretations in at least one important aspect: its central claim is that each of the 12 categories is wholly derivable from the principle of apperception, which goes against the current view that the Deduction is not a proof in a strict philosophical sense and the standard reading that (...) in the Deduction Kant only gives an account of the global applicability of the categories to experience. This novel approach enables a reappraisal of Kant's controversial claim that transcendental self-consciousness is not only a necessary condition of objective experience but also sufficient for it. The book provides an extensive analysis of Kant's theory of transcendental apperception and also explains why the argument of the Transcendental Deduction is both a regressive and a progressive argument.

According to classical physics particles are basic building blocks of the world. These classical particles are distinguishable objects, individuated by unique combinations of physical properties. By contrast, in quantum mechanics the received view is that particles of the same kind are physically indistinguishable from each other and lack identity. This doctrine rests on the quantum mechanical symmetrization postulates together with the “factorist” assumption that each single particle is represented in exactly one factor space of the tensor product Hilbert space of (...) a many-particle system. Even though standard in theoretical physics and the philosophy of physics, the assumption of factorism and the ensuing indistinguishability of particles are problematic. Particle indistinguishability is irreconcilable with the everyday meaning of “particle”, and also with how this term is used in the practice of physics. Moreover, it is a consequence of the standard view that identical quantum particles remain indistinguishable even in the classical limit, which makes a smooth transition to the classical particle concept impossible. Lubberdink and Dieks and Lubberdink have proposed an alternative conception of quantum particles that does not rely on factorism and avoids these difficulties. We further explain and discuss this alternative framework here. One of its key consequences is that particles in quantum theory are not fundamental but emergent; another that once they have emerged, quantum particles are always physically distinguishable and thus possess a physically grounded identity.

The theories of pre-quantum physics are standardly seen as representing physical systems and their properties. Quantum mechanics in its standard form is a more problematic case: here, interpretational problems have led to doubts about the tenability of realist views. Thus, QBists and Quantum Pragmatists maintain that quantum mechanics should not be thought of as representing physical systems, but rather as an agent-centered tool for updating beliefs about such systems. It is part and parcel of such views that different agents may (...) have different beliefs and may assign different quantum states. What results is a collection of agent-centered perspectives rather than a unique representation of the physical world. In this paper we argue that the problems identified by QBism and Quantum Pragmatism do not necessitate abandoning the ideal of representing the physical world. We can avail ourselves of the same puzzle-solving strategies as employed by QBists and pragmatists by adopting a perspectival quantum realism. According to this perspectivalism objects may possess different, but equally objective properties with respect to different physically defined perspectives. We discuss two options for such a perspectivalism, a local and a nonlocal one, and apply them to Wigner’s friend and EPR scenarios. Finally, we connect quantum perspectivalism to the recently proposed philosophical position of fragmentalism. (shrink)

"A work of major importance for the interpretation of Descartes's development and for the understanding of the function of the imagination in Descartes's early works. Descartes's Imagination will be a must in Descartes and imagination studies. It is long overdue."--Eva T. H. Brann, author of The World of Imagination: Sum and Substance "A significant contribution to our understanding of the development of Descartes's philosophy."--William R. Shea, author of The Magic of Numbers and Motion: The Scientific Career of Rene Descartes.

In the context of a critique of James Conant’s (2016) important new reading of the main argument of the Deduction, I present my current, most detailed interpretation of the well-known Leitfaden passage at A79, which in my view has been misinterpreted by a host of prominent readers. The Leitfaden passage is crucial to understanding the argument of, not just the so-called Metaphysical Deduction, but also the Transcendental Deduction. This new account expands and improves upon the account of the Leitfaden I (...) gave in Chap. 5 of Kant’s Deduction From Apperception. While I agree with the core of Conant’s critique of what he calls the ‘layer-cake’ reading of the Deduction argument, in this new account I make clearer my position on why the unity of judgement, in which concepts and intuitions are a priori synthetically unified, is wholly determined in virtue of the unity of apperception as the unitary function of the understanding, without this leading to a strong form of conceptualism such as that of Conant and others.

Prospect Theory (PT) is widely regarded as the most promising descriptive model for decision making under uncertainty. Various tests have corroborated the validity of the characteristic fourfold pattern of risk attitudes implied by the combination of probability weighting and value transformation. But is it also safe to assume stable PT preferences at the individual level? This is not only an empirical but also a conceptual question. Measuring the stability of preferences in a multi-parameter decision model such as PT is far (...) more complex than evaluating single-parameter models such as Expected Utility Theory under the assumption of constant relative risk aversion. There exist considerable interdependencies among parameters such that allegedly diverging parameter combinations could in fact produce very similar preference structures. In this paper, we provide a theoretic framework for measuring the (temporal) stability of PT parameters. To illustrate our methodology, we further apply our approach to 86 subjects for whom we elicit PT parameters twice, with a time lag of 1 month. While documenting remarkable stability of parameter estimates at the aggregate level, we find that a third of the subjects show significant instability across sessions. (shrink)

Based on analyses of a 2016 German survey, this article contributes to debates on ‘societal nature relations’ by investigating the systematic differences between socially specific types of social relations with nature in a flexible capitalist society. It presents a typology of ten different ‘syndromes’ of attitudes toward social and environmental issues, which are then grouped to distinguish between four ideal types of social relationships with nature: dominance, conscious mutual dependency, alienation and contradiction. These are located in Pierre Bourdieu's (1984) social (...) space to illustrate how social relationships with nature correspond to people's positions within the totality of social relations. Understanding how people's perceptions of and actions pertaining to nature are shaped by their positions in these intersecting relations of domination – both within social space and between society and nature – is an important precondition for developing transformative strategies that will be capable of gaining majority support in flexible capitalist societies.

Points-based grading, though now traditional, faces powerful critiques: Such grading creates a low road to passing, it undermines motivation, it wastes time, and it causes stress. It creates an illusion of mathematical precision. It is unfriendly to necessary conditions for satisfactory performance. This paper defends the alternative of specifications grading. Specifications grading grades only on whether work meets a set of expectations for satisfactory performance, with the expectations set at a high but reachable level. With a high bar also comes (...) opportunities to revise unsatisfactory work. I summarize arguments from the literature in support of the system, but I also give account of my two-year experiment in philosophy courses with specifications grading. Compared with points-based grading, specifications grading appears to motivate students better and helps them learn more. I consider objections from both traditionalists and so-called ‘ungraders.’ The former hope to secure the benefits of specifications grading while still keeping points. The latter favor eliminating grading altogether. (shrink)

Does a flourishing life involve pursuing passionate attachments? Can we choose what these passionate attachments will be? This book offers an original theory of how we can actively cultivate our passionate attachments. The author argues that not only do we have reason to view passionate attachments as susceptible to growth, change, and improvement, but we should view these entities as amenable to self-cultivation. He uses Pierre Hadot's and Michel Foucault's accounts of Hellenistic self-cultivation as vital conceptual tools to formulate a (...) theory of cultivating our passionate attachments. First, their accounts offer the conceptual resources for a philosophical theory of how we can cultivate our passionate attachments. Second, the exercises of self-cultivation they focus on allow us to outline a practical method though which we can cultivate our passionate character. Doing this brings out a significantly new dimension to the role of the passionate attachments in the flourishing life and offers theoretical and practical accounts of how we can cultivate them based on the Hellenistic conception of self-directed character change. Cultivating Our Passionate Attachments will be of interest to advanced students and scholars working in virtue ethics, moral philosophy, and ancient philosophy. (shrink)

The surprising aspects of quantum information are due to two distinctly non-classical features of the quantum world: first, different quantum states need not be orthogonal and, second, quantum states may be entangled. Non-orthogonality leads to the blurring of classical distinctions. On the other hand, entanglement leads via non-locality to teleportation and other ``entanglement-assisted'' forms of communication that go beyond what is classically possible. In this article we attempt to understand these new possibilities via an analysis of the significance of entanglement (...) for the basic physical concepts of a ``particle'' and a ``localized physical system''. Classical particles can be individuated on the basis of qualitative differences in their sets of properties. But in entangled states the ``particle labels'' of the quantum formalism usually do not pick out such sets of individuating particle properties. It is sometimes nevertheless possible to think in terms of individual particles, which may be localized; but we argue that in general the structure of quantum mechanics is at odds with such a particle interpretation. This finally leads us to the conclusion that quantum mechanics is best seen as not belonging to the category of space-time theories, in which physical quantities are functions on space-time points. The resulting picture of the quantum world is relevant for our understanding of the way in which quantum theory is non-local, and it sheds light on the novel aspects of quantum information. (shrink)

This book discusses that imagination is as important to thinking and reasoning as it is to making and acting. By reexamining our philosophical and psychological heritage, it traces a framework, a conceptual topology, that underlies the most disparate theories: a framework that presents imagination as founded in the placement of appearances. It shows how this framework was progressively developed by thinkers like Plato, Aristotle, Descartes, and Kant, and how it is reflected in more recent developments in theorists as different as (...) Peirce, Saussure, Wittgenstein, Benjamin, and Bachelard. The conceptual topology of imagination incorporates logic, mathematics, and science as well as production, play, and art. Recognizing this topology can move us past the confusions to a unifying view of imagination for the future. (shrink)

The intention of this paper is to discuss the notion and word "democracy" as a Greek legacy and then to pose the question of the specific challenges to that conception of democracy presented by this historical present, which Heidegger characterizes as the Gestell. Questions concerning the sources of power, the relation of power to peoples and individuals, as well as the shift from power to violence are addressed. Plato, Aristotle, Pericles, Lincoln, Derrida, and Heidegger are the key figures in this (...) discussion. (shrink)

_What is psychotherapy about?_ _What are the similarities and differences of its many forms?_ _What are the most recent developments in the field?_ _Introduction to Psychotherapy_ has been an essential reference book since its publication in 1979, and is regularly included in reading lists for trainee psychotherapists, psychiatrists and other professionals. It is often recommended to interested lay people and prospective patients. This third edition takes into account recent changes in psychotherapy theory, practice and research. The authors are all psychoanalysts. (...) The first edition arose from the experiences of Dennis Brown and Jonathan Pedder working and teaching together as Consultant Psychotherapists at St Mary's Hospital and Medical School, London. (shrink)
