El presente artículo tiene como objetivo analizar y reconstruir la postura de John Stuart Mill respecto del problema de la inducción. Mostraremos que Mill si bien conoció las objeciones de Hume, no se refiere a ellas en gran medida porque para él la justificación de la inducción es posible. La hipótesis principal será probada por medio de dos tesis: la primera, alude a la evasión de la argumentación circular respecto de la justificación de la inferencia inductiva; y la segunda, refiere (...) al tipo de inducciones que fundamentan el principio de regularidad: inducciones por enumeración simple.

Background and Aims: The COVID-19 pandemic has led to radical and unexpected changes in everyday life, and it is plausible that people’s psychophysical health has been affected. This study examined the relationship between COVID-19 related knowledge and mental health in a Croatian sample of participants.MethodsAn online survey was conducted from March 18 until March 23, 2020, and a total of 1244 participant responses were collected. Measures included eight questions regarding biological features of the virus, symptoms, and prevention, the Hospital Anxiety (...) and Depression Scale, and Optimism-Pessimism Scale. According to the answers given on the questions on COVID-19 related knowledge, participants were divided in two groups: informed and uninformed on each question. They were then compared in the expressed levels of anxiety, depression, pessimism, and optimism. Full vs. partial mediation models with optimism/pessimism as a mediator in the relationship between anxiety/depression and the accuracy of responses for questions about handwashing and ways of transmission were estimated.ResultsParticipants who responded correctly on the question about handwashing had higher levels of anxiety, depression, and pessimism than those participants whose answer was incorrect, while participants who answered correctly on the question about the percentage of patients who develop serious breathing problems had higher levels of depression than those who answered incorrectly. Lower levels of anxiety and pessimism were observed in the participants who answered correctly about ways of transmission. Higher levels of pessimism were found in participants who scored incorrectly on questions about the efficiency of antibiotics, most common symptoms, and the possibility of being infected by asymptomatic carriers. Higher levels of knowledge about handwashing were predicted by higher levels of anxiety and pessimism. Higher levels of knowledge about ways of transmission were predicted by lower levels of anxiety and lower levels of pessimism. The examined relationships between anxiety/depression and knowledge were mediated by pessimism.ConclusionThe findings of this study suggest that knowledge about COVID-19 may be useful to reduce anxiety and depression, but it must be directed to the promotion of health behaviors and to the recognition of fake news.

Introduction Hospital delirium is a frequent, serious, costly, and underrecognized acute disorder of attention and cognition. Therefore, the prevention of hospital delirium is not only desirable for patients, caregivers, healthcare professionals, and the health system itself, but also a moral duty. Objective To identify and synthetize the main ethical aspects that arise related to the prevention of hospital delirium in patients 65 years and older. Methods A scoping review was carried out in Embase, Medline, and Web of Science. Articles published (...) in English or Spanish analyzing any pharmacologic, non-pharmacologic, or multicomponent intervention for prevention of delirium in hospitalized patients aged 65 years and over were included. Results Twenty-seven studies were included. Based on the frequency of appearance and the relevance, our findings were organized into three main areas. The first one was related to the principle of nonmaleficence and collected findings about the iatrogenic causes of hospital delirium and the use of restraints systems. The second area analyzed the impact of delirium in patients, families, and healthcare professionals from a relational ethics perspective, and addressed the family presence as a factor to prevent delirium. Finally, the third area is related to the quality of care. Conclusion Prevention of delirium in hospitals is essential to avoid the discomfort and potential clinical complications of patients, as well as the suffering of their relatives, caregivers, and healthcare professionals. Policymakers and healthcare managers are encouraged to make the required efforts to prevent delirium in hospitalized older patients. (shrink)

Theories of embodied cognition hypothesize interdependencies between psychological well-being and physical posture. The purpose of this study was to assess the feasibility of objectively measuring posture, and to explore the relationship between posture and affect and other patient centered outcomes in breast cancer survivors with persistent postsurgical pain over a 12-week course of therapeutic Qigong mind-body training. Twenty-one BCS with PPSP attended group Qigong training. Clinical outcomes were pain, fatigue, self-esteem, anxiety, depression, stress and exercise self-efficacy. Posture outcomes were vertical (...) spine and vertical head angles in the sagittal plane, measured with a 3D motion capture system in three conditions: eyes open, eyes open relaxed and eyes closed. Assessments were made before and after the Qigong training. The association between categorical variables was measured by Cramer’s V. In the EO condition, most participants who improved in fatigue and anxiety scales also had better vertical head values. For the EOR condition, a moderate correlation was observed between changes in vertical head angle and changes in fatigue scale. In the EC condition, most of the participants who improved in measures of fatigue also improved vertical head angle. Additionally, pain severity decreased while vertical spine angle improved. These preliminary findings support that emotion and other patient centered outcomes should be considered within an embodied framework, and that Qigong may be a promising intervention for addressing biopsychosocially complex interventions such as PPSP in BCSs.

Abstract The introduction of genetically modified plants into the environment has been marked by different positions, either in favor of or against their release. However, the problem goes well beyond such contradictory positions; it is necessary to take into account the legislation, ethics, biosafety, and the environment in the considerations related to the release of genetically modified organisms (GMOs). To this end, the Brazilian Committee of Biosafety (CTNBio), a consultative and deliberative multidisciplinary collegiate, provides technical and advisory support to the (...) Brazilian Federal Government. This committee consists of scientists and non-scientists who participate in evaluating the dossiers of companies that are requesting approval by the Brazilian Government; consequently, the aim of this study was to investigate whether commercial approvals of GMOs were associated with the profile of the CTNBio members. Research was based on the minutes taken at CTNBio meetings carried out from 2006 up to 2009, considering law 11.105/2005 and the Constitution of 1988 as legal frameworks, to determine the number of voters in favor of or against releasing genetically modified Bt-maize, Bt-cotton, and herbicide resistant soybeans to be used in Brazilian agriculture. Via the internet, we had access to the curriculum vitae of the CTNBio members through the Plataforma Lattes database of the National Council for Scientific and Technological Development (CNPq), where we found their area of expertise. CTNBio members were divided into expert-for, expert-against, non-expert-for, and non-expert-against. Results showed that CTNBio decisions could be based on technical criteria as well as on the policy of the institution that expert-members were representing.

Resumen: En este artículo reviso la interpretación de Eduardo Nicol de la teoría de la propiedad de Francisco Suárez. Para ello, presento la posición de Suárez acerca de la propiedad y la propiedad privada atendiendo dos cuestiones fundamentales. La primera es si la propiedad y la propiedad privada son derechos; la segunda es si ambos pertenecen a la naturaleza humana o no. Al final, argumento que la lectura de Nicol es insostenible, pues difícilmente puede admitirse que Suárez defendió algún tipo (...) de comunismo.: In this paper I revisit Eduardo Nicol’s interpretation of Suarez’s theory of property. To this purpose, I present Suárez’s account of property and private property focusing on two main aspects. The first is whether property and private property are rights; the second is whether they belong to the human nature or not. Finally, I argue that Nicol’s reading of Suárez is untenable for it can hardly be accepted that Suárez defended some kind of communism. (shrink)

Parental burnout is a unique and context-specific syndrome resulting from a chronic imbalance of risks over resources in the parenting domain. The current research aims to evaluate the psychometric properties of the Spanish version of the Parental Burnout Assessment across Spanish-speaking countries with two consecutive studies. In Study 1, we analyzed the data through a bifactor model within an Exploratory Structural Equation Modeling on the pooled sample of participants obtaining good fit indices. We then attained measurement invariance across both gender (...) and countries in a set of nested models with gradually increasing parameter constraints. Latent means comparisons across countries showed that among the participants’ countries, Chile had the highest parental burnout score, likewise, comparisons across gender evidenced that mothers displayed higher scores than fathers, as shown in previous studies. Reliability coefficients were high. In Study 2, we tested the relations between parental burnout and three specific consequences, i.e., escape and suicidal ideations, parental neglect, and parental violence toward one’s children. The medium to large associations found provided support for the PBA’s predictive validity. Overall, we concluded that the Spanish version of the PBA has good psychometric properties. The results support its relevance for the assessment of parental burnout among Spanish-speaking parents, offering new opportunities for cross-cultural research in the parenting domain. (shrink)

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

IntroductionThis study aimed to evaluate, in adults with mild cognitive impairment, the brain atrophy that may distinguish between three AT biomarker-based profiles, and to determine its clinical value.MethodsStructural MRI was employed to evaluate the volume and cortical thickness differences in MCI patients with different AT profiles, namely, A−T−−: normal AD biomarkers; A+T−−: AD pathologic change; and A+T++: prodromal AD. Sensitivity and specificity of these changes were also estimated.ResultsAn initial atrophy in medial temporal lobe areas was found in the A+T−− and (...) A+T++ groups, spreading toward the parietal and frontal regions in A+T++ patients. These structural changes allowed distinguishing AT profiles within the AD continuum; however, the profiles and their pattern of neurodegeneration were unsuccessful to determine the current clinical status.ConclusionsMRI is useful in the determination of the specific brain structural changes of AT profiles along the AD continuum, allowing differentiation between MCI adults with or without pathological AD biomarkers.

This article provides current Schwartz Values Survey (SVS) data from samples of business managers and professionals across 50 societies that are culturally and socioeconomically diverse. We report the society scores for SVS values dimensions for both individual- and societal-level analyses. At the individual-level, we report on the ten circumplex values sub-dimensions and two sets of values dimensions (collectivism and individualism; openness to change, conservation, self-enhancement, and self-transcendence). At the societal-level, we report on the values dimensions of embeddedness, hierarchy, mastery, affective (...) autonomy, intellectual autonomy, egalitarianism, and harmony. For each society, we report the Cronbach’s α statistics for each values dimension scale to assess their internal consistency (reliability) as well as report interrater agreement (IRA) analyses to assess the acceptability of using aggregated individual level values scores to represent country values. We also examined whether societal development level is related to systematic variation in the measurement and importance of values. Thus, the contributions of our evaluation of the SVS values dimensions are two-fold. First, we identify the SVS dimensions that have cross-culturally internally reliable structures and within-society agreement for business professionals. Second, we report the society cultural values scores developed from the twenty-first century data that can be used as macro-level predictors in multilevel and single-level international business research.

Theory of Mind (ToM) is one of the most relevant concepts in the field of social cognition, particularly in the case of Autism Spectrum Disorders (ASD). Literature showing that individuals with ASD display deficits in ToM is extensive and robust. However, some related issues deserve more research: the heterogeneous profile of ToM abilities in children with ASD and the association between different levels of ToM development and social, pragmatic, and adaptive behaviors in everyday life. The first objective of this study (...) was to identify profiles of children with ASD without intellectual disability (ID), based on explicit and applied ToM knowledge, and compare these profiles with a group of children with typical development (TD). A second objective was to determine differences in symptom severity, adaptive/social behavior, and pragmatic abilities between the profiles identified. Fifty-two children with a clinical diagnosis of ASD without ID and 37 children with TD performed neuropsychological ToM tasks and two vocabulary and memory tests. In addition, all of their mothers completed different questionnaires about applied ToM abilities, severity of ASD symptoms, adaptive/social skills, and pragmatic competence. Two subgroups were identified in the cluster analysis carried out with explicit and applied ToM indicators. The “Lower ToM abilities” profile obtained significantly lower scores than the “Higher ToM abilities” profile on all the ToM measures. Furthermore, the analysis of covariance, controlling for vocabulary and working memory (ANCOVAs), showed statistically significant differences in applied ToM abilities between the two groups of children with ASD without ID and the group with TD. However, only the group with “Higher ToM abilities” achieved similar performance to the TD group on the verbal task of explicit ToM knowledge. Finally, the “Lower ToM abilities” cluster obtained significantly higher scores on autism symptoms (social and communication domains) and lower scores on adaptive behavior and pragmatic skills than the cluster with “Higher ToM abilities”. Taken together, these findings have implications for understanding the heterogeneity in ToM skills in children with ASD without ID, and their differential impact on social, communicative, and adaptive behaviors.

Automatic control of physiological variables is one of the most active areas in biomedical engineering. This paper is centered in the prediction of the analgesic variables evolution in patients undergoing surgery. The proposal is based on the use of hybrid intelligent modelling methods. The study considers the Analgesia Nociception Index to assess the pain in the patient and remifentanil as intravenous analgesic. The model proposed is able to make a one-step-ahead prediction of the remifentanil dose corresponding to the current state (...) of the patient. The input information is the previous remifentanil dose, the ANI variable and the electromyogram signal. Modelling techniques used are Artificial Neural Networks and Support Vector machines for Regression combined with clustering methods. Both training and validation were done with a real dataset from different patients. Results obtained show the potential of this methodology to calculate the drug dose corresponding to a given analgesic state of the patient. (shrink)

The objective of this work was to construct and validate an instrument for assessing resilience to suicide attempts in a Spanish clinical population that has made a previous attempt, and to verify its efficacy for predicting future suicide reattempts at 6 months. For the construction of a Scale of Resilience to Suicide Attempts the theoretical-rational strategy was used. The constructed SRSA-18 consisted of 18 items and 3 subdimensions, had high internal consistency and a high positive correlation with the Suicide Resilience (...) Inventory-25, SRI-25, and to a lesser extent with general resilience scales such as the Connor-Davidson Resilience Scale, CD-RISC and the Resilience Scale of 14 items, RS-14. Additionally, a specific SRSA-18 score predicted future suicide reattempts 6 months after the first attempt. This new scale assesses in a brief and rapid way, through protective factors rather than risk factors, the level of resilience to the suicide attempt in specific clinical subpopulations in hospital emergency services, being able to prevent suicide reattempts with higher lethality.

Child-to-parent violence is a growing public health problem with consequences for perpetrators and families. Most research has focused on individual and family risk factors. However, little is known about its links with individual outcomes. The aim of this study was to analyze the relationships between CPV and psychological distress, suicidal ideation, and self-concept in school-aged adolescents, taking into account the gender perspective. A study was conducted with a sample of 8,115 adolescents, aged between 11 and 16 years from the State (...) of Nuevo León, Mexico. A MANOVA 3 × 2 was performed to analyze the data. The results revealed that adolescents involved in CPV showed higher levels of psychological distress and suicidal ideation and lower levels of family and social self-concept. It was also observed that girls with higher levels of CPV scored the lowest levels of psychological distress and suicidal ideation, as well as the lowest levels of family self-concept. The findings highlight that adolescents and especially girls involved in CPV also report internal maladjustment outcomes. Finally, the results and their implications for research and intervention with adolescents involved in CPV are discussed. (shrink)

This work focuses on the application of machine learning techniques to assist the clinicians in the administration of analgesic drug during general anaesthesia. Specifically, the main objective is to propose the basis of an intelligent system capable of making decisions to guide the opioid dose changes based on a new nociception monitor, the analgesia nociception index. Clinical data were obtained from 15 patients undergoing cholecystectomy surgery. By means of an off-line study, machine learning techniques were applied to analyse the possible (...) relationship between the analgesic dose changes performed by the physician due to the hemodynamic activity of the patients and the evolution of the ANI. After training different classifiers and testing the results under cross validation, a preliminary relationship between the evolution of ANI and the dosage of remifentanil was found. These results evidence the potential of the ANI as a promising index to guide the infusion of analgesia. (shrink)

In this paper, I take up the question of how epistemic injustices can be resisted. Miranda Fricker, who introduced the term to describe situations in which subjects are wronged as knowers, has initially advocated an individualist, virtue-based account to counteract epistemic injustices. Epistemic injustices, however, do not merely operate at an individual level but are rooted in social practices and structures. Arguably therefore, individually virtuous epistemic conduct is not enough to uproot patterns of epistemic injustice. Institutional change and collective (...) actions are needed. Recently, Elizabeth Anderson has proposed such a structural remedy. Diagnosing patterns of social segregation that track existing inequalities to be the principal structural cause of epistemic injustices, Anderson suggests that integration is required to achieve epistemic justice. Pace Anderson, I argue that certain segregated spaces —namely spaces provided by subaltern counter-publics— can function and, in fact, have historically functioned as important sites of epistemic resistance. In particular, I argue that even if integration is sharply distinguished from assimilation, Anderson’s proposal insufficiently acknowledges the subversive potential of those spaces, in which shielded from the gaze of the oppressors, marginally situated subjects can assemble and question hegemonic epistemic practices.

We explore the distinctive characteristics of Mexico's society, politics and history that impacted the establishment of genetics in Mexico, as a new disciplinary field that began in the early 20th century and was consolidated and institutionalized in the second half. We identify about three stages in the institutionalization of genetics in Mexico. The first stage can be characterized by Edmundo Taboada, who was the leader of a research program initiated during the Cárdenas government (1934-1940), which was primarily directed towards improving (...) the condition of small Mexican farmers. Taboada is the first Mexican post-graduate investigator in phytotechnology and phytopathology, trained at Cornell University and the University of Minnesota, in 1932 and 1933, respectively. He was the first investigator to teach plant genetics at the National School of Agriculture and wrote the first textbook of general genetics, Genetics Notes, in 1938. Taboada's most important single genetics contribution was the production of "stabilized" corn varieties. The extensive exile of Spanish intellectuals to Mexico, after the end of Spain's Civil War (1936-1939), had a major influence in Mexican science and characterizes the second stage. The three main personalities contributing to Mexican genetics are Federico Bonet de Marco and Bibiano Fernández Osorio Tafall, at the National School of Biological Sciences, and José Luis de la Loma y Oteyza, at the Chapingo Agriculture School. The main contribution of the Spanish exiles to the introduction of genetics in Mexico concerned teaching. They introduced in several universities genetics as a distinctive discipline within the biology curriculum and wrote genetics text books and manuals. The third stage is identified with Alfonso León de Garay, who founded the Genetics and Radiobiology Program in 1960 within the National Commission of Nuclear Energy, which had been founded in 1956. The Genetics and Radiobiology Program rapidly became a disciplinary program, for it embraced research, teaching, and training of academics and technicians. The Mexican Genetics Society, created by de Garay in 1966, and the development of strains and cultures for genetics research were important activities. One of de Garay's key requirements was the compulsory training of the Program's scientists for at least one or two years in the best universities of the United States and Europe. De Garay's role in the development of Mexican genetics was fundamental. His broad vision encompassed the practice of genetics in all its manifestations. (shrink)

El proceso de aprehensión de lo cognoscible, en la filosofía contemporánea, ha sido tratado desde diversas perspectivas, entre ellas la fenomenológica y la analítica. Cada una de estas perspectivas aportan unos presupuestos filosóficos y procesos metodológicos que nos proporcionan marcos de trabajo para indagar en las vías de aprehensión del conocimiento; sin embargo, empleadas por separado son insuficientes y limitadas. En absoluto se trata de procurar un método universal, sino de integrar e indagar sobre diversos presupuestos, procesos, patrones y estructuras (...) para avanzar en la indagación de la aprehensión del conocimiento. En este sentido, en la primera parte, abordaremos la necesidad de tener reglas (definitorias y estratégicas) para ser parte y avanzar en cualquier «juego», en especial el del conocimiento. En la segunda y tercera, describiremos los «métodos» desarrollados por José Ferrater Mora (operaciones filosóficas) y Nicolai Hartmann (pensar sistemático), los que pueden ser un punto de partida, vías a considerar en este proceso. En la parte final, a modo de contraste, se ofrece en un gráfico un esquema metodológico de los dos métodos analizados. (shrink)

Las órdenes militares dispusieron desde su fundación de mano de obra esclava en sus tierras, pero la institución que mejor sirve para estudiar la esclavitud en los siglos XII y XIII en los reinos de León y Castilla son los hospitales para la redención de cautivos de la Orden de Santiago.

Feng Youlan , auteur d’une célèbre Histoire de la philosophie chinoise , a voulu refonder le néoconfucianisme de Zhu Xi en l’accordant à la philosophie analytique. Son Traité de l’Homme est une phénoménologie de la conscience individuelle, décrite dans chacune des quatre étapes de son ascension vers la sainteté : la conscience naturelle, forme originelle de l’être-au-monde, immédiatement présent au réel sans conscience de soi ; la conscience intéressée, qui se distancie du réel par un calcul de conduite en vue (...) d’un bonheur égoïste ; la conscience morale, naissant d’une prise de conscience de soi comme être-avec-autrui, qui cultive l’altruisme ; la conscience cosmique, celle du Saint qui a compris les raisons de toute chose et communie à la Voie du Ciel . L’un des penseurs chinois les plus subtils du siècle dernier, Feng Youlan a été décrédibilisé par sa tonitruante conversion au maoïsme en 1949.Feng Youlan is the author of a famous History of Chinese Philosophy translated by Derk Bodde in 1937 and 1953 . He attempted to breathe new life into the Neo-Confucianism of Zhu Xi by bringing it into harmony with analytic philosophy. His Essay on Man is a phenomenology of individual consciousness as it rises to saintliness through four stages : natural consciousness, the primary form of existence in which the mind is immediately aware of the objective world, but without self-consciousness ; selfish consciousness, rising above the objective world by calculation, following the quest of self-happiness ; moral consciousness, born from the consciousness of oneself as a social being and developing altruism ; cosmic consciousness, reaching saintliness through the understanding of the truth of everything and uniting oneself with the Way of Heaven . Feng Youlan was one of the most outstanding Chinese philosophers of the last century who, however, lost credibility after his well-publicized conversion to Maoism in 1949. (shrink)

The 1968 Olympic Games in Mexico included innovative practices and technological knowledge of human biology. The first time that cytogenetic techniques had been applied to athletes was in the 1966 European Athletics Championship in Budapest and used on Olympic athletes for the first time in Mexico in 1968. The Genetics and Human Biology Program was created for this purpose in 1966 in close collaboration with the Local Organizing Committee, by Mexican geneticists Alfonso León de Garay and Rodolfo Félix Estrada (...) who led the project. The main objective was to study the genetic and anthropological components which determine an Olympic athlete’s abilities. This investigation studied 1,265 game participants and included family studies, cytological analyses, research on single genes, and the study of sex determination. In terms of influence beyond Mexico, this Program was significant as a site of transnational collaboration. It mobilized cognitive and financial resources, scientific practices, and material culture to set up a clinical laboratory in the Olympic Village. The Program also hosted three international seminars in Mexico City, two before the games, to calibrate clinical trials and anthropological tests. One in 1969 to analyze the results and proceed to their publication in 1974. This manuscript will focus on the PGBH to show how its work fits in the larger tapestry of post-1945 human biological studies. Also, to explore how the Olympic athlete populations studied can be considered laboratories of knowledge production or sites of cognition conceived as specific entities for scientific inquiry, standardization of medical practices, and the production or application of medicines. Finally, through the narrative of the different trajectories and collaborations of the leaders of the PGBH, this manuscript will show how contact between their scientific practices brought cytogenetics and sports together.

Ascensiones in corde. Agostino d'Ippona. Studio di Miranda Leonel.

Lejos de la interpretación de Leon Battista Alberti como prototipo del "hombre universal", GARIN ha reconocido el carácter contradictorio del pensamiento albertiano. En efecto, en la extensa y polifacética obra del humanista genovés coexisten dos visiones antagónicas del hombre y el mundo. A una le corresponde la confianza en la razón, a la otra la constatación del carácter absurdo de la existencia. Este Alberti "sombrío" se expresa en las páginas de Momus y las Intercenales. En ellas, la apelación a una (...) existencia simulada es abordada a través de una risa desacralizadora del ideal humano que alumbró el temprano Renacimiento italiano. Far from the interpretation of Leon Battista Alberti as a prototype of the "universal man", GARIN has analyzed the contradictory nature of Alberti's thought. In fact, in the extensive and versatile work of the Genoese humanist two opposite visions of man and the world coexist: one believes in the power of reason, the other acknowledges the absurdity of life. It is in Momus and the Intercenales that this "somber Alberti" is present. In these texts the appeal to a simulated life is addressed through a form of laughter that demystifies the human ideal of the early Italian Renaissance. (shrink)

Este artículo aborda el aspecto poco estudiado de la ambigüedad moral y jurídica del verdugo —quien históricamente ha permitido al poder político la posibilidad de negación de la violencia moralmente repudiable—, a partir del análisis compa- rativo de tres casos míticos e históricos: 1) el suplicio del capitán Añasco a manos de la Gaitana durante la Conquista, 2) el martirio de Becket provocado por los caballeros de Enrique II de Inglaterra y 3) las masacres de liberales en la cordillera occidental (...) colombiana durante la Violencia. Se demuestra que la legitimidad de la violencia cruel se encuentra ligada a los conceptos de deber y sacrificio, pero requiere también una posibilidad de negación que preserve la moralidad de la au- toridad. Un demonio sin instrucciones que ejecuta autónomamente una voluntad colectiva de castigo aparece como mecanismo histórico necesario para modular la relación que el poder político mantiene con la crueldad funcional a sus fines.
