Many sensory states motivate. I offer an account of how such states compel intentional action. I focus on thirst as it is relatively simple in physiological and behavioral terms, it carries little theoretical baggage, and the motivational story for thirst seems likely to generalize. I argue that thirst motivates using a variety of flexible strategies, and that no single explanatory mechanism fully captures its motivational force. The resulting view, the aggregation model of sensory motivation, offers the most (...) plausible account of how sensory states motivate. (shrink)

[Author's summmary, 2020]. Motivation specifically to drink (ingest watery materials) is widely assumed (still) to be innate, i.e. independent of exposure to fluids in contexts and sensory, somatic and/or social effects of their consumption. This comment floats the idea that human infants learn to differentiate textures of low-energy fluids from semi-solid and solid foods after they begin to be weaned from milk as sole drink and food.

Background Thirst and dry mouth are common symptoms in terminally ill patients. In their day-to-day practice, palliative care physicians regularly encounter ethical dilemmas, especially regarding artificial hydration. Few studies have focused on thirst and the ethical dilemmas palliative care physicians encounter in relation to this, leading to a knowledge gap in this area. Aim The aim of this study was to explore palliative care physicians’ experiences of ethical challenges in relation to thirst in terminally ill patients. Methods (...) A qualitative interview study with an inductive approach was conducted. Sixteen physicians working in four different specialised palliative care units and one geriatric care unit in different hospitals in Sweden were interviewed. The interviews were transcribed verbatim and analysed with a reflexive thematic analysis. Results When presented with an ethical challenge relating to thirst, physicians attempted to balance benefits and harms while emphasizing respect for the patient’s autonomy. The ethical challenges in this study were: Starting, continuing or discontinuing drips; lack of evidence and traditions create doubt; and lack of interest and time may result in patient suffering. Conclusions All physicians in this study reported that “Starting, continuing or discontinuing drips” was the main ethical challenge they encountered, where some were so accustomed to the decision that they had a standard answer ready to offer patients and families. Physicians reported that drips were a symbol of thirst quenching, life and survival but were not necessary in end-of-life care. Others questioned the traditions regarding thirst and emphasised drips in particular. (shrink)

The neural and endocrine bases of the generation of thirst are reviewed. Based on this review, a hierarchical system of neural structures that regulate water conservation and acquisition is proposed. The system includes primary sensory-receptive areas; secondary sensory structures (circumventricular organs), which detect levels of hormones, including angiotensin II and vasopressin, which are involved in generating thirst; preoptic and hypothalamic structures; and an area within the ventrolateral quadrant of the periaqueductal gray matter. Hodological and other data are used (...) to determine the hierarchical organization of the system. Based on studies of the effects of lesions to various structures within the hierarchy of the system, it is proposed that the awareness of thirst in rodents is either entirely or predominantly due to neuronal activities in a subsection of the ventrolateral periaqueductal gray matter. It is also hypothesized that the awareness of thirst in primates is due to neuronal activities in both the ventrolateral periaqueductal gray and in a region within the medial prefrontal and anterior cingulate cortex.

This paper seeks to examine the smuggling of tea during the long eighteenth century through several facets. In order to understand why smuggling occurred throughout the eighteenth century, one must take into consideration the laws which necessitated the need for smuggling, as well as the economic environment of Britain throughout the century. In addressing the widescale phenomena of ritualized tea drinking, one can comprehend why tea, specifically, was selected to be smuggled, admittedly among a myriad of other valuable commodities. It (...) is also critical to explore the materiality of tea ritual, as well as the smuggling process, as objects are a crucial element to the narrative and development of tea and its associated illicit activities. Bringing these components of examination together, one may begin to understand why tea was smuggled during the eighteenth century, and how the British government consequently worked to end smuggling altogether.

I argue that Plato’s account of hunger and thirst in Republic IV, 437d–439a uncovers a general feature of desire: desire has an unqualified and a qualified dimension. This proposal, which I call Two Dimensions, captures recognizable motivational phenomena: being hungry and aiming to determine what one is hungry for, or wanting to study and still figuring out what field it is that one wants to study. Two Dimensions is a fundamental contribution to the theory of desire. It is compatible, (...) I argue, with the better known premise that desire is for the good, because the objects of paradigmatic desires are inherently valuable. (shrink)

This essay represents a novel contribution to Nietzschean studies by combining an assessment of Friedrich Nietzsche’s challenging uses of “truth” and the “eternal return” with his insights drawn from Indian philosophies. Specifically, drawing on Martin Heidegger’s Nietzsche, I argue that Nietzsche’s critique of a static philosophy of being underpinning conceptual truth is best understood in line with the Theravada Buddhist critique of “self ” and “ego” as transitory. In conclusion, I find that Nietzsche’s “eternal return” can be understood as a (...) direct inversion of “nirvana”: Nietzsche celebrates profound attachment to each and every moment, independent from its pleasurable or distasteful registry.

Definitions of nature and transcendence are given, and the framework of Hindu thought is presented. The levels of reality as discovered by physics are then discussed, which leads us to revise our notions of reality and objectivity. Transcendence is defined as something beyond matter‐energy in space‐time and is explored in several contexts of modern science, as in pre‐Big‐Bang state, negative entropy, information, complexity, and others. Finally, a philosophical reflection on consciousness is presented.

This book focuses on justice and its demands in the way of providing people with medical care. Building on recent insights on the nature of moral perceptions and motivations from the neurosciences, it makes a case for the traditional medical ethic and examines its financial feasibility. The book starts out by giving an account of the concept of justice and tracing it back to the practices and tenets of Hippocrates and his followers, while taking into account findings from the neurosciences. (...) Next, it considers whether the claim that it is just to limit medical care for everyone to some basic minimum is justifiable. The book then addresses finances and expenditures of the US health care system and shows that the growth of expenditures and the percentage of the gross national product spent on health care make for an unsustainable trajectory. In light of the question what should be changed, the book suggests that overdiagnosis and medicalizing normal behavior lead to harmful, costly and unnecessary interventions and are the result of unethical behavior on the part of the pharmaceutical industry and extensive ethical failures of the FDA. The book ends with suggestions about what can be done to put the U.S. health care system on the path to sustainability, better medical care, and compliance with the demands of justice. (shrink)

This reply to Carolina Sartorio’s “Resultant Luck and the Thirsty Traveler” begins with a discussion of earlier treatments of the thirsty traveler puzzle. I emphasize the way in which adjustments to the case can elicit varying intuitions and conclude with a suggestion as to why the case is so difficult to analyze. Next, I turn to Sartorio’s analysis of the puzzle. I largely agree with her judgments about the causal issues in the case but I am less certain about the (...) conclusions she draws with respect to moral responsibility. I conclude with some reflections on Sartorio’s claim that causation and moral responsibility come apart in the thirsty traveler puzzle. I suggest that this might be true in a way other than the one that Sartorio has in mind; my proposal raises issues about moral luck in addition to those that Sartorio considers. (shrink)

Osobliwość takich doznań, jak ból, głód i pragnienie. Reliabilizm w drugiej części szóstej Medytacji Kartezjusza Artykuł omawia epistemiczny status cielesnych doznań takich, jak ból, głód i pragnienia, o których mowa w drugiej części szóstej Medytacji Kartezjusza. Argumentuję, że ów fragment stanowi integralny komponent epistemologicznego programu, który można znaleźć w Medytacjach. Na ogół widzi się Kartezjusza jako zwolennika infallibilizmu, internalizmu oraz fundacjonalizmu. Tymczasem w odniesieniu do wiedzy i przekonań opartych na doznaniach cielesnych przyjmuje on fallibilizm, eksternalizm i reliabilizm. Na rzecz tego (...) wniosku przemawia z jednej strony, analiza tego, czego naucza nas – według Kartezjusza – natura przez wrażenia bólu, głodu i pragnienia, z drugiej strony jego analiza błędów, którym podlega nasza natura, przeprowadzona przeze mnie z wykorzystaniem zaproponowanego przez Wilfrida Sellarsa podziału na logiczną przestrzeń rozumu oraz empiryczną przestrzeń przyczyn.
