This chapter addresses the problem of the designer’s responsibility for his own choices and the way in which its request should be transmitted to new generations. It deals with the problem of ethics in architecture and how it could be possible to overcome the de-responsibility induced by homologated forms consumprtion, which end up constituting a reassuring repertoire. It is therefore necessary to study the deep transformations substratum of the built environment which explains why things are as they appear. Studying the formative processes of the built reality, the different changing phases, the project should be considered as the critical, last phase of transformation, that of the near future. The reading of the transformation processes does not provide a solution but offers a series of congruent possibilities from which the designer has the responsibility to choose and which he is required to express through a personal aesthetic synthesis. The reading of the built reality cannot be, in other words, a description, but a vital and operative interpretation.
