Yellow sun in a blue sky. Green leaves caressed by the wind. Open the shutters of the eye, that window of the soul, and all such things are revealed. Nothing is more apparent than that things have colors, and that we have immediate perceptual access to those colors.

Background:Ethical conflict and subsequent nurse moral distress and burnout are common in the intensive care unit (ICU). There is a gap in our understanding of nurses’ perceptions of how organizational resources support them in addressing ethical conflict in the intensive care unit.Research question/objectives/methods:The aim of this qualitative, descriptive study was to explore how nurses experience ethical conflict and use organizational resources to support them as they address ethical conflict in their practice.Participants and research context:Responses to two open-ended questions were collected (...) from critical care nurses working in five intensive care units at a large, academic medical center in the Midwestern region of the United States.Ethical considerations:This study was approved by the Institutional Review Board at the organization where the study took place.Findings:Three main interwoven themes emerged: nurses perceive (1) intensive care unit culture, practices, and organizational priorities contribute to patient suffering; (2) nurses are marginalized during ethical conflict in the intensive care unit; and (3) organizational resources have the potential to reduce nurse moral distress. Nurses identified ethics education, interprofessional dialogue, and greater involvement of nurses as important strategies to improve the management of ethical conflict.Discussion:Ethical conflict related to healthcare system challenges is intrinsic in the daily practice of critical care nurses. Nurses want to be engaged in discussions about their perspectives on ethical conflict and play an active role in addressing ethical conflict in their practice. Organizational resources that support nurses are vital to the resolution of ethical conflict.Conclusion:These findings can inform the development of interventions that aim to proactively and comprehensively address ethical conflict in the intensive care unit to reduce nurse moral distress and improve the delivery of patient and family care.

At the end of a thoughtful article on the future of nuclear war, Wiesner and York concluded that: "Both sides in the arms race are... confronted by the dilemma of steadily increasing military power and steadily decreasing national security. It is our considered professional judgment that this dilemma has no technical solution. If the great powers continue to look for solutions in the area of science and technology only, the result will be to worsen the situation.".

Tainted political symbols ought to be confronted, removed, or at least recontextualized. Despite the best efforts to achieve this, however, official actions on tainted symbols often fail to take place. In such cases, I argue that political vandalism—the unauthorized defacement, destruction, or removal of political symbols—may be morally permissible or even obligatory. This is when, and insofar as, political vandalism serves as fitting counter-speech that undermines the authority of tainted symbols in ways that match their publicity, refuses to let them (...) speak in our name, and challenges the derogatory messages expressed through a mechanism I call derogatory pedestalling: the glorification or honoring of certain individuals or ideologies that can only make sense when members of a targeted group are taken to be inferior.

In a book that challenges the most widely held ideas of why individuals engage in collective conflict, Russell Hardin offers a timely, crucial explanation of group action in its most destructive forms. Contrary to those observers who attribute group violence to irrationality, primordial instinct, or complex psychology, Hardin uncovers a systematic exploitation of self-interest in the underpinnings of group identification and collective violence. Using examples from Mafia vendettas to ethnic violence in places such as Bosnia and Rwanda, he (...) describes the social and economic circumstances that set this violence into motion. Hardin explains why hatred alone does not necessarily start wars but how leaders cultivate it to mobilize their people. He also reveals the thinking behind the preemptive strikes that contribute to much of the violence between groups, identifies the dangers of "particularist" communitarianism, and argues for government structures to prevent any ethnic or other group from having too much sway. Exploring conflict between groups such as Serbs and Croats, Hutu and Tutsi, Northern Irish Catholics and Protestants, Hardin vividly illustrates the danger that arises when individual and group interests merge. In these examples, groups of people have been governed by movements that managed to reflect their members' personal interests--mainly by striving for political and economic advances at the expense of other groups and by closing themselves off from society at large. The author concludes that we make a better and safer world if we design our social institutions to facilitate individual efforts to achieve personal goals than if we concentrate on the ethnic political makeup of our respective societies.

Criteria are given to characterize mature theories in contradistinction to developing theories. We lean heavily on the physical sciences. An established theory is defined as a mature one with known validity limits. The approximate truth of such theories is thereby given a quantitative character. Superseding theories do not falsify established theories because the latter are protected by their validity limits. This view of scientific realism leads to ontological levels and cumulativity of knowledge. It is applied to a defense of realism (...) against recent attacks by Laudan. (shrink)

A prominent way of justifying civil disobedience is to postulate a pro tanto duty to obey the law and to argue that the considerations that ground this duty sometimes justify forms of civil disobedience. However, this view entails that certain kinds of uncivil disobedience are also justified. Thus, either a) civil disobedience is never justified or b) uncivil disobedience is sometimes justified. Since a) is implausible, we should accept b). I respond to the objection that this ignores the fact that (...) civil disobedience enjoys a special normative status on account of instantiating certain special features: nonviolence, publicity, the acceptance of legal consequences, and conscientiousness. I then show that my view is superior to two rivals: the view that we should expand the notion of civility and that civil disobedience, expansively construed, is uniquely appropriate; and the view that uncivil disobedience is justifiable in but only in unfavorable conditions.

Many realists have maintained that the success of scientific theories can be explained only if they may be regarded as approximately true. Laurens Laudan has in turn contended that a necessary condition for a theory's being approximately true is that its central terms refer, and since many successful theories of the past have employed central terms which we now understand to be non-referential, realism cannot explain their success. The present paper argues that a realist can adopt a view of reference (...) according to which a theory might plausibly be said to be approximately true even though its central terms do not refer, or alternatively, he may construe reference in such a way as to assign reference to a range of successful older theories which includes Laudan's purported counterexamples.

Many have argued that certain statues or monuments are objectionable, and thus ought to be removed. Even if their arguments are compelling, a major obstacle is the apparent historical value of those commemorations. Preservation in some form seems to be the best way to respect the value of commemorations as connections to the past or opportunities to learn important historical lessons. Against this, I argue that we have exaggerated the historical value of objectionable commemorations. Sometimes commemorations connect to biased or (...) distorted versions of history, if not mere myths. We can also learn historical lessons through what I call repudiatory honouring: the honouring of certain victims or resistors that can only make sense if the oppressor(s) or target(s) of resistance are deemed unjust, where no part of the original objectionable commemorations is preserved. This type of commemorative practice can even help to overcome some of the obstacles objectionable commemorations pose against properly connecting to the past. (shrink)
