In this article we have proposed to make a critical approach to two significant topics of Benjamin’s work: modernity and history. From them, we are convinced that we can realize the complexity and originality of his thinking. An originaty that was not intended to become a fashion but a mechanism that would allow us to understand the constituent time of our existence.En este artículo nos hemos propuesto realizar una aproximación crítica a dos tópicos significativos de la obra de Benjamin: modernidad e historia. A partir de ellos, estamos convencidos, que podemos percatarnos de la complejidad y originalidad de su pensamiento. Una originalidad que no pretendía constituirse en una moda sino en un mecanismo que permitiera comprender el tiempo constituyente de nuestras de existencia.
