Act-utilitarianism and other theories in normative ethics confront the implementability problem: normal human agents, with normal human epistemic abilities, lack the information needed to use those theories directly for the selection of actions. Two Level Theories have been offered in reply. The theoretical level component states alleged necessary and sufficient conditions for moral rightness. That component is supposed to be true, but is not intended for practical use. It gives an account of objective obligation. The practical level component is offered (...) as an implementable system for the choice of actions by agents lacking some relevant information. It gives an account of subjective obligation. Several different ways of developing Two Levelism are explained and criticized. Five conditions that must be satisfied if the practical level principle is to be a good match for a given theoretical level principle are stated. A better form of Two Levelism is presented. (shrink)

Previous studies of auditory expectation have focused on the expectedness perceived by listeners retrospectively in response to events. In contrast, this research examines predictive uncertainty —a property of listeners' prospective state of expectation prior to the onset of an event. We examine the information-theoretic concept of Shannon entropy as a model of predictive uncertainty in music cognition. This is motivated by the Statistical Learning Hypothesis, which proposes that schematic expectations reflect probabilistic relationships between sensory events learned implicitly through exposure. Using (...) probability estimates from an unsupervised, variable-order Markov model, 12 melodic contexts high in entropy and 12 melodic contexts low in entropy were selected from two musical repertoires differing in structural complexity (simple and complex). Musicians and non-musicians listened to the stimuli and provided explicit judgments of perceived uncertainty (explicit uncertainty). We also examined an indirect measure of uncertainty computed as the entropy of expectedness distributions obtained using a classical probe-tone paradigm where listeners rated the perceived expectedness of the final note in a melodic sequence (inferred uncertainty). Finally, we simulate listeners' perception of expectedness and uncertainty using computational models of auditory expectation. A detailed model comparison indicates which model parameters maximize fit to the data and how they compare to existing models in the literature. The results show that listeners experience greater uncertainty in high-entropy musical contexts than low-entropy contexts. This effect is particularly apparent for inferred uncertainty and is stronger in musicians than non-musicians. Consistent with the Statistical Learning Hypothesis, the results suggest that increased domain-relevant training is associated with an increasingly accurate cognitive model of probabilistic structure in music.

Holding unlimited economic freedom to be nearly as dangerous as physical violence, Karl Popper advocated “piecemeanl” economic intervention by the state. Jeremy Shearmur's recent book on Popper contends that as the philosopher aged, his views grew closer to classical liberalism than those expressed in The Open Society—consistently with what Shearmur sees as the logic of Popper's arguments. But Popper's philosophy, while recognizing that any project aimed at bringing about social change must be immensely complex and fraught with difficulty, retains grounds (...) for hope about the purposeful use of government to bring about desirable social results.

The central dilemma concerning randomized clinical trials (RCTs) arises out of some simple facts about causal methodology (RCTs are the best way to generate the reliable causal knowledge necessary for optimally-informed action) and a prima facie plausible principle concerning how physicians should treat their patients (always do what it is most reasonable to believe will be best for the patient). A number of arguments related to this in the literature are considered. Attempts to avoid the dilemma fail. Appeals to informed (...) consent and mechanisms for minimizing the resulting harm are important for policy, but informed consent is problematic and mechanisms for minimization of harm do not address the dilemma. Appeals to some sort of contract model of justification are promising and illuminating. Keywords: randomized clinical trials, ethics CiteULike Connotea Del.icio.us What's this? (shrink)

A basic function of cognition is to detect regularities in sensory input to facilitate the prediction and recognition of future events. It has been proposed that these implicit expectations arise from an internal predictive coding model, based on knowledge acquired through processes such as statistical learning, but it is unclear how different types of statistical information affect listeners’ memory for auditory stimuli. We used a combination of behavioral and computational methods to investigate memory for non-linguistic auditory sequences. Participants repeatedly heard (...) tone sequences varying systematically in their information-theoretic properties. Expectedness ratings of tones were collected during three listening sessions, and a recognition memory test was given after each session. Information-theoretic measures of sequential predictability significantly influenced listeners’ expectedness ratings, and variations in these properties had a significant impact on memory performance. Predictable sequences yielded increasingly better memory performance with increasing exposure. Computational simulations using a probabilistic model of auditory expectation suggest that listeners dynamically formed a new, and increasingly accurate, implicit cognitive model of the information-theoretic structure of the sequences throughout the experimental session.

In comments originally presented at the ISUS conference at Dartmouth College in 2005, Elinor Mason and Alastair Norcross raised a number of objections to various things I said in Pleasure and the Good Life. One especially interesting objection concerns one of my central claims about the nature of pleasure. I distinguished between sensory pleasure and attitudinal pleasure. I said that a feeling counts as a sensory pleasure if the one who feels it takes intrinsic attitudinal pleasure in the fact that (...) he is then feeling it. I also said that attitudinal pleasure is a propositional attitude that does not intrinsically involve any particular 'feelings'. On my view, a person can take attitudinal pleasure in things at a time even though he does not feel any pleasurable feelings at that time. In their comments, Mason and Norcross expressed doubts about my account of attitudinal pleasure. In my reply, I try to answer those doubts. (shrink)

While unionization rates have steadily declined in the United States, there has been a renewal of grassroots labor organizing—in many cases connected in some way with religious communities. Attending to such organizing efforts holds the potential to deepen religious-ethical reflection on questions of labor, and these religious-ethical reflections hold the potential to enrich on-the-ground organizing efforts. These opportunities have largely been overlooked. On the one hand, while scholars have recently explored connections between religious ideas and economic ideas, they have often (...) neglected questions of labor. On the other hand, labor studies scholars have often ignored the role of religion, although this is beginning to change. In this introduction we limn the resources available for religious-ethical reflection on questions of labor and we propose a direction that the field could take, bringing together engagement with religious traditions and attunement to grassroots organizing.

What is it for me to do something is the question discussed in the present paper. It has been suggested that my doings are elicited by tryings, intentions, and other causal mechanisms. These theories do not offer any convincing analysis of what it is for me to act. Insight is sought by looking at some case studies involving temporary loss of the ability to move oneís body. What the case studies show, I conclude, is that when I move my body (...) in the normal way, I do not first have to do something else that causes my body to move. Normal actions are events bodily beings can generate spontaneously . An essential condition for having this kind of control is inside awareness of the body. When inner awareness of the body is lost, control can be taken over by visual awareness. But then movement loses its spontaneous character and depends on planning and intense concentration. One can think of the self from which my actions flow, as the mental life to which they belong, or as the consciousness that controls them. (shrink)
