We start a new "blue" series in Arquitectonics, titled Advanced Theories and Practices, dedicated to the research on architecture and urban planning, with an introductory volume to the subject of the relations between mind, land and society. This has been possible thanks to the web of co-edition between different universities and to a new international scientific committee of very high level. This issue includes lectures presented at the International Congress on Arquitectonics, which took place in Barcelona in 2004, and summarizes moreover three lectures of architects in this same Congress, with "good" practice. We maintain the papers' "spoken" version, as if it were another "practical" level, even though this implies a certain disorder in the texts.

Este nuevo volumen de la serie azul de Arquitectonics esta dedicado a las relaciones siempre complejas entre la arquitectura y su uso por la sociedad. Hemos intentado que los diferentes paradigmas existentes hoy en esta tematica esten aqui representados. Un comentario especial merece el articulo del profesor y filosofo Victor Gomez Pin, sobre la facilidad con la que los arquitectos olvidamos la naturaleza de nuestro trabajo, donde geometria y significado social no pueden disociarse sin caer en la total frivolidad o en la mas evidente irresponsabilidad cultural. This new volume of the blue series of Arquitectonics is dedicated to the always complicated relations between architecture and its use by society. We have aimed to include the different paradigms that are found in this thematic today. It is worth to make a special comment on the article by the professor and philosopher, Victor Gomez Pin, on how easily we architects forget about the nature of our work, where geometry and social significance cannot be dissociated without falling into total frivolity or into the most evident cultural irresponsibility.

El presente libro establece los fundamentos de un saber hacer arquitectura que no se identifique unicamente con el espacio de la construccion, en concordancia con las posturas humanistas de Occidente. Se estructura en tres partes complementarias, dedicadas a las tres dimensiones basicas de la arquitectura: la estetica, la etica-politica y la cientifica, unidas a traves de un nucleo dialogico-social del hecho arquitectonico que da solidez, simultaneamente, tanto al diseno arquitectonico como a su construccion y a su uso. El libro se complementa con un amplio anexo que contiene la version castellana de algunos articulos publicados recientemente en otros idiomas sobre los ultimos avances en la comprension cultural de la significacion de la "arquitectura" de nuestra mente, de nuestro territorio y de nuestra sociedad.
