This essay considers and evaluates recent results and arguments from classical chaotic systems theory and non-relativistic quantum mechanics that pertain to the question of whether our world is deterministic or indeterministic. While the classical results are inconclusive, quantum mechanics is often assumed to establish indeterminism insofar as the measurement process involves an ineliminable stochastic element, even though the dynamics between two measurements is considered fully deterministic. While this latter claim concerning the Schrödinger evolution must be qualified, the former fully depends (...) on a resolution of the measurement problem. Two alleged proofs that nature is indeterministic, relying, in turn, on Gleason's theorem and Conway and Kochen's recent 'free will theorem', are shown to be wanting qua proofs of indeterminism. We are thus left with the conclusion that the determinism question remains open. (shrink)

No one in philosophy has paid much attention to the virtue of honesty in recent years. Here is a trait for which it is easy to find consensus that it is a virtue, and furthermore, a very important virtue. It also has obvious relevance to what we see going on in contemporary politics, for instance, or in sports, the entertainment world, and education. Yet as far as I can tell, only one article in a philosophy journal has appeared in several (...) decades which discusses this virtue at any length. -/- In this chapter I have two central aims: (i) to sketch some of the conceptual parameters of the virtue of honesty in general, as well as its subordinate virtues, and then (ii) to draw on leading work in psychology to determine, at least in a preliminary way, whether we should think that most people instantiate this virtue or not.

This article examines the methodology of a core branch of contemporary political theory or philosophy: “analytic” political theory. After distinguishing political theory from related fields, such as political science, moral philosophy, and legal theory, the article discusses the analysis of political concepts. It then turns to the notions of principles and theories, as distinct from concepts, and reviews the methods of assessing such principles and theories, for the purpose of justifying or criticizing them. Finally, it looks at a recent debate (...) on how abstract and idealized political theory should be, and assesses the significance of disagreement in political theory. The discussion is carried out from an angle inspired by the philosophy of science. (shrink)

Thanks largely to the work of Robert Adams and Philip Quinn, the second half of the twentieth century witnessed a resurgence of interest in divine command theory as a viable position in normative theory and meta-ethics. More recently, however, there has been some dissatisfaction with divine command theory even among those philosophers who claim that normative properties are grounded in God, and as a result alternative views have begun to emerge, most notably divine intention theory (Murphy, Quinn) and divine motivation (...) theory (Zagzebski). My goal here is to outline a distinct theory, divine desire theory, and suggest that, even if it is not clearly superior to these extant views, it is at least worthy of serious consideration.1 As far as this paper is concerned, the discussion will be limited just to the deontic status of actions (obligatory, permissible, forbidden), and so no attempt will be made to also account for axiological properties such as goodness or evil. In order to get oriented to the range of deontological views in this area, consider the following three rough characterizations. (shrink)

Within child and adolescent psychiatry, there are a number of potential dilemmas pertaining to diagnosis, treatment, the protection of the child, as well as the child's own developing intelligence and moral judgement. Diagnostic Dilemmas in Child and Adolescent Psychiatry is the first in the IPPP series to explore this highly complex topic.

Distributed cognition refers to processes which are (i) cognitive and (ii) distributed across multiple agents or devices rather than performed by a single agent. Distributed cognition has attracted interest in several fields ranging from sociology and law to computer science and the philosophy of science. In this paper, I discuss distributed cognition from a social-choice-theoretic perspective. Drawing on models of judgment aggregation, I address two questions. First, how can we model a group of individuals as a distributed cognitive system? Second, (...) can a group acting as a distributed cognitive system be ‘rational’ and ‘track the truth’ in the outputs it produces? I argue that a group’s performance as a distributed cognitive system depends on its ‘aggregation procedure’ – its mechanism for aggregating the group members’ inputs into collective outputs – and I investigate the properties of an aggregation procedure that matter.

In two recent books, I have drawn on hundreds of studies in psychology in order to systematically develop and empirically support a new conception of the character traits which I claim most people possess. Here I will focus on just one underexplored area of the psychological literature – research on harmful as opposed to helpful behavior – and use it in a preliminary way to further support my positive view.
