En enero de 1974 Zubiri dio un breve curso en la Sociedad de Estudios y Publicaciones de Madrid sobre el tema 'Tres dimensiones del ser humano - individual, social e histórica'. Meses después publicó la última de esas lecciones bajo el título de 'La dimensión histórica del ser humano'. El presente volumen recoge el texto de las tres conferencias, más la versión escrita de la última de ellas. La tesis que Zubiri desarrolla en estas lecciones es que el ser humano es a la vez y necesariamente individual, social e histórico, y que estas dimensiones vienen exigidas por su propia realidad específica, que es pluralizante, continuante y prospectiva.

The Liberating Philosophy of Ignacio Ellacuría: Historical Reality, Humanism, and Praxis is the first systematic work on the philosophy of Ignacio Ellacuría to be published in English so far. The Spaniard-Salvadorian philosopher—murdered in Salvador in 1989 by the military—maintains that philosophy is a permanent task grounded in metaphysics as first philosophy, as developed within a historical reality and a preferential option for the poor. As explored by this collection edited by Luis Arturo Martínez Vásquez, Randall Carrera Umaña, and Luis Rubén Díaz Cepeda, Ellacuría's theory is a critical and practical proposal immersed in the colonial history of Central America, but its explanatory and normative power extends to oppressed people all around the world. The contributors to this volume, coming from Spain, Mexico, Argentina, Salvador, and Costa Rica, analyze Ellacuría's philosophy of liberation in conjunction with radical realism and strength, describing it as "a philosophy created by people concerned with the problems and history of our land—such as our colonial past, systemic poverty and dependency—and… responding to these concerns can offer alternatives for a true liberation of all the dominated peoples of the world."

Our definition as rational animals has expired, since we now know that other species also have that characteristic. Hence the inquiry in this regard and its corresponding result, which are addressed in this book and whose conclusion is that evolution itself has endowed us with something specific: our ability to devise, based on which all and only sapiens live an external reality, in relation to the environment, and an internal reality, based on our personal worldview, and which we also symbolize, especially through language and other cultural expressions. That is why our closest definition corresponds to that of Animal of realities. To facilitate both the exposure and understanding of this proposal, it is summarized in a File or Identity Card that informs about our origin, nature, essence and spirit; also described by a triple metaphor: "The Democritus Effect, to demonstrate the capacity for ideation of homo sapiens. "The Marseillaise Effect, to illustrate how that capacity is transformed into culture. "And the Ashoka Effect, so that we can direct this capacity towards companies of a social nature. In summary, this book deals with our identity essence, raison d'être and "universal passport", based on our nature and evolutionary specification. Metaphorically, it can also be said that it contains more information and applications than any device, and that it is easily activated: through interest. If you want to know why and for what we are here and, ultimately, what is our identity and our fit into this Universe, both individually and collectively
