This classic remains one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history.

Described by the philosopher A.J. Ayer as a work of 'great originality and power', this book revolutionized contemporary thinking on science and knowledge. Ideas such as the now legendary doctrine of 'falsificationism' electrified the scientific community, influencing even working scientists, as well as post-war philosophy. This astonishing work ranks alongside The Open Society and Its Enemies as one of Popper's most enduring books and contains insights and arguments that demand to be read to this day.

Popper formulates and explains his non-justificationist theory of knowledge. Science--empirical science--aims at true explanatory theories, yet it can never prove, finally establish, or justify any of its theories as true, not even if it is in fact a true theory. Science must continue to question and criticize all its theories, even those which happen to be true.

On its publication in 1957, _The Poverty of Historicism_ was hailed by Arthur Koestler as 'probably the only book published this year which will outlive the century.' A devastating criticism of fixed and predictable laws in history, Popper dedicated the book to all those 'who fell victim to the fascist and communist belief in Inexorable Laws of Historical Destiny.' Short and beautifully written, it has inspired generations of readers, intellectuals and policy makers. One of the most important books on the (...) social sciences since the Second World War, it is a searing insight into the ideas of this great thinker. (shrink)

‘If in this book harsh words are spoken about some of the greatest among the intellectual leaders of mankind, my motive is not, I hope, to belittle them. It springs rather from my conviction that, if our civilization is to survive, we must break with the habit of deference to great men.’ - Karl Popper, from the Preface Written in political exile during the Second World War and first published in two volumes in 1945, Karl Popper’s _The Open Society and (...) Its Enemies _is one of the most influential books of all time. Hailed by Bertrand Russell as a ‘vigorous and profound defence of democracy’, its now legendary attack on the philosophies of Plato, Hegel and Marx exposed the dangers inherent in centrally planned political systems and through underground editions become an inspiration to lovers of freedom living under communism in Eastern Europe. Popper’s highly accessible style, his erudite and lucid explanations of the thoughts of great philosophers and the recent resurgence of totalitarian regimes around the world are just three of the reasons for the enduring popularity of _The Open Society and Its Enemies_ and why it demands to be read today and in years to come.

The basic theme of Popper's philosophy--that something can come from nothing--is related to the present situation in physical theory. Popper carries his investigation right to the center of current debate in quantum physics. He proposes an interpretation of physics--and indeed an entire cosmology--which is realist, conjectural, deductivist and objectivist, anti-positivist, and anti-instrumentalist. He stresses understanding, reminding us that our ignorance grows faster than our conjectural knowledge.

Pedro Álvarez (Cuba) y Rafael Trelles (Puerto Rico) son dos importantes exponentes de la plástica contemporánea en el Caribe hispano que encontraron en dos hitos artísticos del siglo xix una vía para cuestionar las fórmulas fijadas por la Historia y el Arte. Ambos, a partir de la reapropiación de la obra de Víctor Patricio Landaluze y Francisco Oller, respectivamente, reflexionan sobre las complejas circunstancias de sus islas. Mediante el estudio del pasado ambos se preocupan comprometidamente por el sentido de su (...) historia patria, por la (re) actualización de su tradición artística o las funciones del intelectual en la configuración de sus contextos nacionales. La fragmentación y el collage resultan métodos constructivos eficaces que utilizan ambos artistas para descontextualizar los múltiples signos culturales de sus referentes de partida y readecuar sus múltiples significados en la nueva obra, y en el nuevo contexto. Sin embargo, a pesar de las semejanzas se advierten igualmente diferencias de intención, de acuerdo a las respectivas realidades nacionales. (shrink)

'I want to begin by declaring that I regard scientific knowledge as the most important kind of knowledge we have', writes Sir Karl Popper in the opening essay of this book, which collects his meditations on the real improvements science has wrought in society, in politics and in the arts in the course of the twentieth century. His subjects range from the beginnings of scientific speculation in classical Greece to the destructive effects of twentieth century totalitarianism, from major figures of (...) the Enlightenment such as Kant and Voltaire to the role of science and self-criticism in the arts. The essays offer striking new insights into the mind of one of the greatest twentieth century philosophers. (shrink)

Background Moral resilience is the integrity and emotional strength to remain buoyant and achieve moral growth amid distressing situations. Evidence is still emerging on how to best cultivate moral resilience. Few studies have examined the predictive relationship of workplace well-being and of organizational factors with moral resilience. Research aims The aims are to examine associations of workplace well-being (i.e., compassion satisfaction, burnout, and secondary traumatic stress) and moral resilience, and to examine associations of workplace factors (i.e., authentic leadership and perceived (...) congruence of organizational mission and behaviors) and moral resilience. Research design This study uses a cross-sectional design. Participants and research context: Nurses practicing in a hospital in the United States were surveyed using validated instruments (N = 147). Individual factors were measured using demographics and the Professional Quality of Life Scale. Organizational factors were measured using the Authentic Leadership Questionnaire and a single item measuring organizational mission/behavior congruence. Moral resilience was measured using the Rushton Moral Resilience Scale. Ethical considerations The study was approved by an institutional review board. Findings Resilience was noted to have significant small correlations with burnout, secondary traumatic stress, compassion satisfaction, and organizational mission/behavior congruence. Burnout and secondary traumatic stress predicted less resilience, whereas compassion satisfaction and perceived congruence between organizational mission and behaviors predicted higher resilience. Discussion Burnout and secondary traumatic stress, increasingly experienced by nurses and other health professionals, have negative effects on moral resilience. Compassion satisfaction can increase resilience, which is especially important in nursing. Organizational practices promoting integrity and confidence can have positive effects on resilience. Conclusions Continued work to confront workplace well-being issues, especially burnout, is needed as a way of increasing moral resilience. Studies of organizational and work environment factors to bolster resilience are likewise needed to assist organizational leaders in devising the best strategies. (shrink)

A natural extension of Natural Deduction was defined by Schroder-Heister where not only formulas but also rules could be used as hypotheses and hence discharged. It was shown that this extension allows the definition of higher-level introduction and elimination schemes and that the set $\{ \vee, \wedge, \rightarrow, \bot \}$ of intuitionist sentential operators forms a {\it complete} set of operators modulo the higher level introduction and elimination schemes, i.e., that any operator whose introduction and elimination rules are instances of (...) the higher-level schemes can be defined in terms of $\{ \vee, \wedge, \rightarrow, \bot \}$.The aim of the present work is to extend the well-known connections between Proof Theory and Category Theory to higher-level Natural Deduction. To be precise, we will show how an adjointness between cartesian closed categories with finite coproducts can be associated, in a systematic way, with any operator $\phi$ defined by the higher-level schemes. The objects in the categories will be rules instead of formulas. (shrink)

A sampling of the philosophical writings of Karl Popper includes discussions of rationalism, knowledge, human freedom, and the scientific method.

Entre 1927 y 1933 Walter Benjamin escribió guiones radiofónicos que fueron transmitidos en Radio Berlín y Radio Fráncfort, y que él mismo actuó y narró al aire, o bien, dirigió y participó en su producción. Aunque el propio Benjamin veía con cierto desdén esas colaboraciones, y de forma similar lo han hecho los estudiosos de su obra —en buena medida por dirigirse al público infantil—, estos trabajos resultan en particular relevantes porque concretan los postulados teóricos del filósofo berlinés en términos (...) de forma y contenido. Este artículo busca mostrar la coherencia entre el trabajo que Benjamin realizó para la radio y su obra filosófica; explorar aquellas piezas radiofónicas para destacar su filo crítico y la manera en que manifiestan la búsqueda presente en Benjamin desde sus escritos de juventud: el despertar del sueño de la modernidad capitalista.

Moral Judgments, Moral Virtues, and Moral Norms The paper consists of two basic parts. In the first, contemporary approaches to moral judgments and their relations with moral virtues and moral norms are analyzed. The focus is on comparing the role of the emotions and reason, and conscious and unconscious processes in forming and/or justifying moral judgments. The second part examines views on the current broader socio-political situation in Western countries and points to the growing feelings of insecurity among people mainly (...) due to the fact that traditional ways of life have been losing solid ground, settled norms and ethical systems are weakening and at the same time the social trust in various state institutions and bureaucratic structures involved in power is decreasing. In conclusion the author argues for the potential of the ethic of autonomy that would lead to still greater cooperation in globalized ethic, primarily thanks to our moral emotions and moral judgments.

Normativity: Approaches, Polemics, Problems.

The article approaches the topic of social trust from an evolutionary perspective. It begins by summarising the most influential approaches that have defined specific and social trust and ascertains what causes differences in degrees of trust and how the potential risk of deception might be lowered. It then notes that the basis of morality had already been formed during the era of prehistoric man, who was able to create coalitions against aggressors and to socially control the behaviour of deviants. It (...) points out, however, that having a certain predisposition to behaving cooperatively or an increased sensitivity to recognising and not tolerating behaviour aimed at abusing cooperation is not a sufficient guarantee of the fact that people will always (or at least in the majority of situations) favour cooperation over deception. One of the reasons for this is a tendency to favour short-term gains over long-term ones. The article argues that establishing norms (moral, social and legal) produces a higher level of social trust because it not only “encourages” individuals to behave in certain ways in particular situations but also works as a sanction which “discourages” the individual from socially deviant behaviour. The article then focuses on a debate about the causal relationship between social trust and social capital. It discusses the suggestion that political institutions, government and the judiciary may reduce rather than raise levels of social capital and consequently also the level of social trust. This is partly because of their powerful position and the consequent scope for corruption and partly because of the fact that even when attempting to act honestly, representatives of these institutions cannot sufficiently reflect upon dynamic change at the local level. Finally, the article ends by adopting the position that social trust is built primarily from bottom up and so it is risky to continually doubt the very existence and usefulness of social norms and morality and to be governed simply by legal norms.

In this long-awaited volume, Jeremy Shearmur and Piers Norris Turner bring to light Popper's most important unpublished and uncollected writings from the time of The Open Society until his death in 1994. After The Open Society: Selected Social and Political Writings reveals the development of Popper's political and philosophical thought during and after the Second World War, from his early socialism through to the radical humanitarianism of The Open Society. The papers in this collection, many of which are available here (...) for the first time, demonstrate the clarity and pertinence of Popper's thinking on such topics as religion, history, Plato and Aristotle, while revealing a lifetime of unwavering political commitment. After The Open Society illuminates the thought of one of the twentieth century's greatest philosophers and is essential reading for anyone interested in the recent course of philosophy, politics, history and society.

The paper deals with cognitive interview, a method for pre-testing survey questions that is used in pilot testing to develop new measures and/or adapt ones in foreign languages. The aim is to explore the usefulness of the method by looking at two questionnaires measuring anti-Roma prejudice. The first, the Stereotype Content Model (SCM), contains questions that are dominantly used to test two dimensions of social perceptions of various groups: warmth and competence. The second, Interventions for Reducing Prejudice against Stigmatized Minorities (...) (INTERMIN) consists of the items most frequently used in contact research to measure attitudes, social distance, anxiety, trust and behavioural intentions towards outgroups. Two rounds of cognitive interviews were held on both questionnaires to verbally evaluate participants’ understanding and/or interpretation of the draft questions. The first round was attended by university students, while the second round (with improved versions of the questionnaires) was done with high school students, as they are the target group for planned interventions based on the contact paradigm. The paper explains the problems/difficulties the participants had answering some of the questions and our attempts at improving the questionnaires. The problems can be grouped around six issues: The first two deal with the strategies participants used to answer our questions – whom exactly did they have in mind when answering the questionnaires and whose viewpoint did they represent in their answers. The next four problems are around nuances in the formulations of our questions and generally have to do with how the participants interpreted our questions – they concern assumptions that distinct items were logically interconnected, the period of time and locality referred to in our questions, translation and transferability of meanings from one language to another and double negation.

En los poemas declamatorios y descriptivos que reúne AP 9, un motivo de inspiración es la destrucción de Troya, la cantada por Homero, y se relaciona el enclave minorasiático con Micenas o con Roma y con situaciones críticas como la animadversión de los dioses, el colapso de la ciudad y los avatares de sus protagonistas. Esta investigación exploratorio-analítica pretende comprobar en trece textos escogidos qué causas, consecuencias y episodios vinculados con dicho conflicto bélico son centrales y coincidentes -entre otras razones, (...) por la interacción entre repertorios- y qué detalles aporta cada poeta, en consonancia con la permanencia de tales componentes en el imaginario colectivo griego. In the declamatory and descriptive poems which GA 9 gathers, a source of inspiration is the destruction of Troy, sung by Homer, and the enclave of Minor Asia is linked with Mycenae or Rome and with critical situations like enmity of the gods, the collapse of the city and their protagonists’ ups and downs. This exploratory-analytical research aims to verify in thirteen selected texts which reasons, consequences and episodes related to the above mentioned warlike conflict are central and coincident -among other causes, because of the interaction between repertoires- and what details each poet contributes with, in agreement with the permanence of such components in Greek collective imaginary.

The essays in this volume represent an approach to human knowledge that has had a profound influence on many recent thinkers. Popper breaks with a traditional commonsense theory of knowledge that can be traced back to Aristotle. A realist and fallibilist, he argues closely and in simple language that scientific knowledge, once stated in human language, is no longer part of ourselves but a separate entity that grows through critical selection.

Physical and chemical processes may act upon the mind; and when we are writing a difficult letter, our mind acts upon our body and, through a chain of physical...

_Conjectures and Refutations_ is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.

It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.

The way in which knowledge progresses, and especially our scientific knowledge, is by unjustified anticipations, by guesses, by tentative solutions to our problems, by conjectures. These conjectures are controlled by criticism: that is, by attempted refutations, which include severely critical tests. They may survive these tests; but they can never be positively justified: they can neither be established as certainly true nor even as 'probable'. Criticism of our conjectures is of decisive importance: by bringing out our mistakes it makes us (...) understand the difficulties of the problems which we try to solve. This is how we become better acquainted with our problem, and able to propose more mature solutions: the very refutation of a theory - that is, of a tentative solution to our problem - is always a step forward that takes us nearer the truth. And this is how we can learn from our mistakes. As we learn from our mistakes our knowledge grows, even though we may never know - that is, know for certain. Since our knowledge can grow, there can be no reason here for despair of reason. And since we can never know for certain, the can be no authority here for any claim to authority, for conceit over our knowledge, or for smugness. The essays and lectures of which this book is composed apply this thesis to many topics, ranging from problems of the philosophy and history of the physical and social sciences to historical and political problems.

This article provides an overview of a number of research studies conducted within the field of parenthood and reproduction in a variety of Western cultures, including Slovakia and the countries of Eastern Europe. The main aim of this overview is to analyse two key indicators on Second Demographic Transition: delaying marriage and parenthood until later on in life and the growth in cohabitation as an alternative living arrangement and childbearing as part of that. The author points out that the majority (...) of parents opt to have a first child and this brings normative and emotional fulfilment. Most young people do not reject this, but simply postpone it until later on in life. The hypothesis is postulated that the decision on whether to have further children is to a larger extent rationally based and is more dependent on weighing up the incentives available from the state. The article emphasises, on the basis of a comparison of the results of various empirical studies, that the same patterns of reproductive behaviour can produce markedly different consequences and outcomes within various subgroups of the population. It is recommended that current research into parenthood and reproduction should be extended so that studies are conducted into similar groups within subpopulations across different countries—in contrast to the current prevailing research that is focused on single countries or in comparing different countries as a whole. It is also recommended that the scope of the research be extended to compare a number of different subpopulations with similar value and life-style configurations as opposed to the majority of the current narrowly-focused approaches that concentrate on examining the differences in reproductive behaviour patterns of a section of the population selected on the basis of education.
