This paper suggests a method to calculate a degree of validity for the proof of a statement which is derived from empirical statements by means of logic conclusions. The empirical statements are assumed not to be completely valid or their validity to be doubtful. The suggested rules are consistent with two-valued logic, yield decreasing validities with increasing number of applications of modus ponens and obey the law of the excluded middle. The actual calculation of validity values, the relation of the (...) suggested method to some truth tables of multi-valued logic and to fuzzy logic are discussed. (shrink)

In spite of the importance of point mutations for evolution and human diseases, their natural spectrum of incidence in different species is not known. Here I propose to determine these spectra by comparing consecutive sequence periods in stretches of repetitive DNA. The article presents the analysis of more than 51,000 such point mutations identified by this approach in the genomes of human, chimpanzee, rat, mouse, pufferfish, zebrafish, and sea squirt. I propose to explain the observed spectra by auto‐mutagenic mechanisms of (...) genome variation involving the inter‐conversions of nucleotides, single base‐pair inversions and their combinations.

There has recently been much interest in the role of attention in controlling action. The role has been mischaracterized as an element in necessary and sufficient conditions on agential control. In this paper I attempt a new characterization of the role. I argue that we need to understand attentional control in order to fully understand agential control. To fully understand agential control we must understand paradigm exercises of agential control. Three important accounts of agential control—intentional, reflective, and goal-represented control—do not (...) fully explain such exercises. I argue that understanding them requires understanding how deployments of visual attention implement flexible occurrent control, or a capacity to flexibly adjust the degree of control that individuals exercise over their actions. While such deployments of attention are neither necessary nor sufficient for exercising agential control, they constitute an attentional skill for controlling action, understanding which is central to fully understanding agential control. We can appreciate its centrality if we appreciate that this attentional skill for controlling action is plausibly crucial to acting non-negligently. (shrink)

How do individuals guide their activities towards some goal? Harry Frankfurt once identified the task of explaining guidance as the central problem in action theory. An explanation has proved to be elusive, however. In this paper, I show how we can marshal empirical research to make explanatory progress. I contend that human agents have a primitive capacity to guide visual attention, and that this capacity is actually constituted by a sub-individual psychological control-system: the executive system. I thus illustrate how we (...) can explain exercises of individual-level guidance by appeal to its sub-individual constitution. This opens up a new avenue for explicating agency. (shrink)

Skilled action typically requires that individuals guide their activities toward some goal. In skilled action, individuals do so excellently. We do not understand well what this capacity to guide consists in. In this paper I provide a case study of how individuals shift visual attention. Their capacity to guide visual attention toward some goal (partly) consists in an empirically discovered sub-system – the executive system. I argue that we can explain how individuals guide by appealing to the operation of this (...) sub-system. Understanding skill and skilled action thus requires appreciating the role of the executive system. (shrink)

What is attention? On one influential position, attention constitutively is the selection of some stimulus for coupling with a response. Wayne Wu has proposed a master argument for this position that relies on the claim that cognitive science commits to an empirical sufficient condition (ESC), according to which, if a subject S perceptually selects (or response-couples) X to guide performance of some experimental task T, she therein attends to X. In this paper I show that this claim about cognitive science (...) is false. Cognitive science allows for inattentive selection-for-task, or inattentive response-coupling. This means that Wu’s account is without independent support. (shrink)

This article is concerned with the concept of “informed consent” as applied both in biomedical research involving human subjects and in clinical medicine in general. The current crisis over the elaboration and interpretation of the concept will be examined, along with the broader question of whether “informed consent” is any longer meaningful or viable as a criterion for complex bioethical policy-making. Finally, I will attempt to sketch a prognosis for the concept in doctor-patient relations, even if it is only wishful (...) thinking. (shrink)

In paradigm exercises of agency, individuals guide their activities toward some goal. A central challenge for action theory is to explain how individuals guide. This challenge is an instance of the more general problem of how to accommodate individuals and their actions in the natural world, as explained by natural science. Two dominant traditions–primitivism and the causal theory–fail to address the challenge in a satisfying way. Causal theorists appeal to causation by an intention, through a feedback mechanism, in explaining guidance. (...) Primitivists postulate primitive agential capacities in their explanations. The latter neglect to explain how primitive capacities integrate with findings from natural science. The former do not explain why some feedback mechanism’s activity amounts to the agent’s guidance. In this paper I argue that both traditions should acknowledge a capacity to guide, as actually constituted by the executive system. I argue that appeals to this empirically discovered psychological system explain how individuals guide in a way that integrates with explanations from cognitive science. Individuals’ capacity to guide is embedded in the natural world through the activity of its constituent (mechanistic) components. (shrink)

One of the most influential recent accounts of attention is Wayne Wu’s. According to Wu, attention is selection-for-action. I argue that this proposal faces a dilemma: either it denies clear cases of attention capture, or it acknowledges these cases but classifies many inattentive episodes as attentive.

Recently, there has been much interest in epistemic roles of attention, especially in whether visual attention is necessary for warranting (basic) visual belief. Arguably it is not. But attention nevertheless has important roles to play in our warrant from vision. I argue that we must appeal to a competence for shifting visual attention in explaining transsaccadic vision and our epistemic warrant from it. So even if it is not necessary for visual warrant or vision, visual attention plays a central role (...) in both. (shrink)

Sells encourages a radical departure from the usual introspection and self-centeredness of psychology in our time. By placing style first, Sells argues that we must turn our eyes and minds outward to the greater world. Emphasizing beauty over emotion and appreciation over feeling, he attempts to break the stranglehold of the self so as to reconstitute our proper place among the many things of the world.

Executive functioning has been said to bear on a range of traditional philosophical topics, such as consciousness, thought, and action. Surprisingly, philosophers have not much engaged with the scientific literature on executive functioning. This lack of engagement may be due to several influential criticisms of that literature by Daniel Dennett, Alan Allport, and others. In this paper I argue that more recent research on executive functioning shows that these criticisms are no longer valid. The paper clears the way to a (...) more fruitful philosophical engagement with findings on the central executive system. (shrink)

In this paper, I present the case of the discovery of complex numbers by Girolamo Cardano. Cardano acquires the concepts of (specific) complex numbers, complex addition, and complex multiplication. His understanding of these concepts is incomplete. I show that his acquisition of these concepts cannot be explained on the basis of Christopher Peacocke’s Conceptual Role Theory of concept possession. I argue that Strong Conceptual Role Theories that are committed to specifying a set of transitions that is both necessary and sufficient (...) for possession of mathematical concepts will always face counterexamples of the kind illustrated by Cardano. I close by suggesting that we should rely more heavily on resources of Anti-Individualism as a framework for understanding the acquisition and possession of concepts of abstract subject matters.

Given that as much as half of human thought arises in a stimulus independent fashion, it would seem unlikely that such thoughts would play no functional role in our lives. However, evidence linking the mind-wandering state to performance decrement has led to the notion that mind-wandering primarily represents a form of cognitive failure. Based on previous work showing a prospective bias to mind-wandering, the current study explores the hypothesis that one potential function of spontaneous thought is to plan and anticipate (...) personally relevant future goals, a process referred to as autobiographical planning. The results confirm that the content of mind-wandering is predominantly future-focused, demonstrate that individuals with high working memory capacity are more likely to engage in prospective mind-wandering, and show that prospective mind-wandering frequently involves autobiographical planning. Together this evidence suggests that mind-wandering can enable prospective cognitive operations that are likely to be useful to the individual as they navigate through their daily lives. (shrink)

The current research investigates the interaction between thought suppression and individuals’ explicit awareness of their thoughts. Participants in three experiments attempted to suppress thoughts of a prior romantic relationship and their success at doing so was measured using a combination of self-catching and experience-sampling. In addition to thoughts that individuals spontaneously noticed, individuals were frequently caught engaging in thoughts of their previous partner at experience-sampling probes. Furthermore, probe-caught thoughts were: associated with stronger decoupling of attention from the environment, more likely (...) to occur under cognitive load, more frequent for individuals with a desire to reconcile, and associated with individual differences in the tendency to suppress thoughts. Together, these data suggest that individuals can lack meta-awareness that they have begun to think about a topic they are attempting to suppress, providing novel insight into the cognitive processes that are involved in attempting to control undesired mental states.

The first English translation of the major political works of Benjamin Constant (1767-1830), one of the most important of the French political figures in the aftermath of the revolution of 1789, and a leading member of the liberal opposition to Napoleon and later to the restored Bourbon monarchy. The texts included in this volume are widely regarded as one of the classic formulations of modern liberal doctrine.

The 2013 Ebola virus outbreak in West Africa, as of writing, is declining in reported human cases and mortalities. The resulting devastation caused highlights how health systems, in particular in West Africa, and in terms of global pandemic planning, are ill prepared to react to zoonotic pathogens. In this paper we propose One Health as a strategy to prevent zoonotic outbreaks as a shared goal: that human and Great Ape vaccine trials could benefit both species. Only recently have two phase (...) 2/3 Ebola human vaccine trials been started in West Africa. This paper argues for a conceptual change in pandemic preparedness. We first discuss the ethics of One Health. Next, we focus on the current Ebola outbreak and defines its victims. Third, we present the notion of a ‘shared benefit’ approach, grounded in One Health, and argue for the vaccination of wild apes in order to protect both apes and humans. We believe that a creation of such inter-species immunity is an exemplar of One Health, and that it is worth pursuing as a coextensive public health approach. (shrink)

This paper has two aims. The first is to present and defend a new argument for rights contributionism – the view that the notion of a moral claim-right is a contributory (or pro tanto) rather than overall normative notion. The argument is an inference to the best explanation: it is argued that (i) there are contributory moral factors that contrast with standard moral reasons by way of having a number of formal properties that are characteristic of rights, even though they (...) can be overridden, and (ii) that this is best explained by a view that takes these factors to correlate with rights. The second aim is to show that the truth of rights contributionism matters for normative ethics. More specifically, it is argued that rights contributionism clears the way for deontologists to justify the pre-theoretically plausible verdict that we have a duty to save the greater number in so-called Taurek scenarios – scenarios in which we have to choose between saving either a greater or a smaller number of different people. The chapter offers a novel and distinctively deontological explanation of this verdict that is based on the assumption that everyone has a pro tanto right to be saved in a Taurek scenario. (shrink)

Both traditional and naturalistic epistemologists have long assumed that the examination of human psychology has no relevance to the prescriptive goal of traditional epistemology, that of providing first-person guidance in determining the truth. Contrary to both, I apply insights about the psychology of human perception and concept-formation to a very traditional epistemological project: the foundationalist approach to the epistemic regress problem. I argue that direct realism about perception can help solve the regress problem and support a foundationalist account of justification, (...) but only if it is supplemented by an abstractionist theory of concept-formation, the view that it is possible to abstract concepts directly from the empirically given. Critics of direct realism like Laurence BonJour are correct that an account of direct perception by itself does not provide an adequate account of justification. However a direct realist account of perception can inform the needed theory of concept-formation, and leading critics of abstractionism like McDowell and Sellars, direct realists about perception themselves, fail to appreciate the ways in which their own views about perception help fill gaps in earlier accounts of abstractionism. Recognizing this undercuts both their objections to abstractionism and (therefore) their objections to foundationalism. (shrink)
