La unidad del pensamiento Aldo Guarneros Monterrubio Filosofía vida Unidad límite historia principio Este ensayo trata sobre la investigación del principio de unidad. Para ello examino la unidad en relación con el pensamiento. El pensamiento es comprendido en tres sentidos: como la unidad del objeto de investigación, como la unidad del desarrollo histórico y como principio vital del quehacer filosófico. Estos sentidos muestran la posibilidad de continuar con la investigación de la verdad. El diálogo con la tradición y los sentidos que ésta dona al concepto de pensamiento nos permiten comprender la dificultad de dicha investigación, no con la finalidad de ceder ante ella, sino para contribuir en la búsqueda. El propósito es abrirse paso en lo previamente pensado para repensarlo y enriquecerlo desde la época actual. 2014 artículo científico 1870-879X https://www.redalyc.org/articulo.oa?id=141132947004 es http://www.redalyc.org/revista.oa?id=1411 En-claves del Pensamiento application/pdf Instituto Tecnológico y de Estudios Superiores de Monterrey En-claves del Pensamiento (México) Num.16 Vol.VIII
