This chapter aims to illuminate ways in which hope was significant in the philosophy of classical Greece. Although ancient Greek philosophies contain few dedicated and systematic expositions on the nature of hope, they nevertheless include important remarks relating hope to the good life, to reason and deliberation, and to psychological phenomena such as memory, imagination, fear, motivation, and pleasure. After an introductory discussion of Hesiod and Heraclitus, the chapter focuses on Plato and Aristotle. Consideration is given both to Plato’s direct (...) comments on hope and to the narrative contexts of his dialogues, with analysis of Plato’s positive and negative representations of hope, hope’s relationship to reason, and Plato’s more psychological approach in the Philebus, where hope finds a place among memory, recollection, pleasure, and pain. The chapter then reviews Aristotle’s discussions of confidence, hope, and courage, observing that although Aristotle does not mention hope as a virtue, he does note its importance to human agency and deliberation and as a foundation for the further development of virtue. The chapter concludes that discussions surrounding hope in ancient Greek philosophy are rich and challenging and can serve as a lively stimulus to further exploration of the concept of hope.

Now in its Third Edition, Philosophy of Language: A Contemporary Introduction introduces students to the main issues and theories in twentieth-century philosophy of language, focusing specifically on linguistic phenomena. Author William G. Lycan structures the book into four general parts. Part I, Reference and Referring, includes topics such as Russell's theory of descriptions (and its objections), Donnellan's distinction, problems of anaphora, the description theory of proper names, Searle's cluster theory, and the causal-historical theory. Part II, Theories of Meaning, surveys the (...) competing theories of linguistic meaning and compares their various advantages and liabilities. Part III, Pragmatics and Speech Acts, introduces the basic concepts of linguistic pragmatics and includes a detailed discussion of the problem of indirect force. Part IV, The Expressive and the Figurative, examines various forms of expressive language and what "metaphorical meaning" is and how most listeners readily grasp it. (shrink)

Organisms that share the capability of storing information about experiences in the past have an actively generated background resource on which they can compare and evaluate more recent experiences in order to quickly or even better react than in previous situations. This is an essential competence for all reaction and adaptation purposes of living organisms. Such memory/learning skills can be found from akaryotes up to unicellular eukaryotes, fungi, animals and plants, although until recently, it had been mentioned only as a (...) capability of higher animals. With the rise of epigenetics, the context-dependent marking of experiences at both the phenotype and the genotype level is an essential perspective to understand memory and learning in all organisms. Both memory and learning depend on a variety of successful communication processes within the whole organism. (shrink)

COVID-19 has stolen millions of lives and devastated livelihoods around the world and led to the exacerbation of existing inequities within and between countries. This part of a tragic pattern in catastrophes, where the most vulnerable populations are typically the ones to bear the greatest burdens. Jecker and Au1 offer a keen observation of how one particular COVID-19 response—Zero COVID—appears particularly problematic from a health equity perspective. Under Zero COVID, countries enact stringent lockdowns and movement restrictions in order to keep (...) cases as low as possible. Yet such restrictive policies hurt disadvantaged populations the most, by severely curtailing their ability to earn a living and forcing them to remain in cramped living spaces for potentially extended periods of time. However, the link between Zero COVID and health inequity is more complex than it might at first appear. This is because Zero COVID is itself compatible with meaningful efforts to mitigate inequities, including those caused by Zero COVID policies themselves. Conversely, certain inequities seemingly characterised by Zero COVID may persist even when Zero COVID is abandoned, indicating their ultimate root and …. (shrink)

In this paper, we have considered a dynamical model of Chlamydia disease with varying total population size, bilinear incidence rate and pulse vaccination strategy. We have defined two positive numbers $$R_{0}$$ R 0 and $$R_{1}$$ R 1. It is proved that there exists an infection-free periodic solution which is globally attractive if $$R_{0} 1.$$ R 1 > 1. The important mathematical findings for the dynamical behaviour of the Chlamydia disease model are also numerically verified using MATLAB. Finally epidemiological implications of (...) our analytical findings are addressed critically. (shrink)

Excerpt from Zur Psychologie des Asthetischen Genusses Die erste Erfahrung, auf der uberhaupt die Existenz berechtigung einer Wissenschaft wie der Asthetik beruht, ist die, da durch Einwirkung gewisser Objekte auf unsere Sinne ein Wohlgefallen in uns erzeugt wird, das wir unmittelbar und mit ziemlicher Sicherheit von allen anderen Arten des Wohlgefallens unterscheiden. Wenn wir versuchen, diesen zunachst nur gefiihlten Unterschied zu begrifi'licher Klarheit emporzuheben, so bemerken wir, da das asthetische Wohl gefallen durch zwei Eigenschaften charakterisiert und von allen anderen Arten (...) des Glucksgefiihls geschieden ist: erstens knupft es sich nicht an Elementarvorstellungen also ein fache Empfindungen sondern an Vorstellungskomplexe, und zweitens setzt es nicht die reale oder gedachte Erfullung einer zielsetzenden Tatigkeit voraus, sondern hat sein Ziel allein in sich selbst. Durch die erste Bestimmung unterscheidet es sich von sinnlichen Lustgefuhlen, durch die zweite von allen anderen Arten des Wohlgefallens, die wir aus leicht ersieht lichen Grunden als praktisch bezeichnen wollen.

Levesque et al. have defined a programming language, Golog, in order to reason about complex actions within the framework of the situation calculus. We build on previous work of ours and show how to translate Golog into linear logic, suitably augmented.

The verb “to conjure” is a complex one, for it includes in its standard definition a great range of possible actions or operations, not all of them equivalent, or even compatible. In its most common usage, “to conjure” means to perform an act of magic or to invoke a supernatural force, by casting a spell, say, or performing a particular ritual or rite. But “to conjure” is also to influence, to beg, to command or constrain, to charm, to bewitch, to (...) move or convey, to imagine, to visualize, to call to mind, or to remember. —Rachael DeLue 2012, para 1. When we create with our Brown hands, feminine energy, and full spirits, we conjure. To exist, survive, and thrive in these bodies is a continuous act of conjuring. Our walks conjure. Our smiles conjure. Our tears conjure. Our laughs conjure. Our words conjure. Our artworks are conjurings. We, a Black/Filipina-American woman, a Dominican-American, and a Black-American woman, are guided by our solidarity with one another and all other Black and Brown female identifying persons whose raced and gendered subjectivities exist both inside and outside of colonization, white supremacy, and patriarchy. We bring to life our colored imaginations and curiosities, and share them with the world. We are united by our need for safety, autonomy as beings, dissolution of trauma, and desire to ask, “What would happen if I…?” Imaginative, curious Women of Color (WoC) founded the underground railroad, guided captured Africans and Tainos to the mountains, ignited the Civil Rights Movement, organized laborers and immigrants, birthed the #BlackLivesMatter Movement, conceived the #MeToo Movement, and so much more. Like our kindred counterparts, we have an unrelenting urge to examine, question, wonder, desire, speak to, lead, be curious, and “conjure.” As practicing artists and art educators, our critical arts-based practices are grounded in intersectional feminisms like Womanism, Black Feminist Theory, and Chicana Feminist Theory, which allow us to do these very things.

Monitored Emergency Use of Unregistered and Experimental Interventions (MEURI) is an ethical framework developed by the WHO for using unproven interventions in public health emergencies outside the context of medical research. It is mainly intended for use when medical research would be impracticable, but there is still a need to systematically gather data about unproven interventions. As such, it is designed as something of a middle ground between clinical and research ethical frameworks.However, I argue that MEURI does not truly lie (...) at the intersection of clinical care and research. Due to its intent, structure and oversight requirements, it takes on most of the crucial features of research, to the point that it is best understood as a form of research. As a result, cases where MEURI could practicably be applied should instead make use of existing research frameworks. For those circumstances where research is truly impracticable, a more straightforward oversight system than MEURI is needed. While existing practices of compassionate use have some applicability, proposals to make use of clinical ethics committees to oversee unproven interventions may help achieve the right balance in acting in a patient’s best interests when the relevant evidence base is weak.
