Romper el tedio en busca de nuevos relatos: una interpelación a las ciencias sociales Martín Hopenhayn Estudios Territoriales Ciencias sociales Ritualismo académico Relatosemancipatorios Construcción social de conocimiento La ritualización de las ciencias sociales en el mundo académicoimpone una dinámica de producción de conocimientos de especialización y rigidezprogresivas. Esto hace difícil crear nuevos relatos emancipatórios, vale decir, pro-veer horizontes de sentido que ayuden a inscribir las acciones de actores políticosy sociales en estrategias de profundización democrática, sostenibilidad ambiental,igualdad social y mejor convivencia en la diversidad. Por otro lado, fuera de laacademia, en el mundo de las redes y de organizaciones de diverso tipo, se producemucho conocimiento social liberado del ritualismo academicista, y con potenciali-dad para concurrir en nuevos relatos movilizadores en torno a un imaginario globalde derechos civiles, políticos, sociales, culturales y de solidaridad intergeneracional. 2015 artículo científico 0717-6554 https://www.redalyc.org/articulo.oa?id=30541588013 es http://www.redalyc.org/revista.oa?id=305 POLIS, Revista Latinoamericana application/pdf Universidad de Los Lagos POLIS, Revista Latinoamericana (Chile) Num.41 Vol.14
