Men redesigning Men is a research that intends to contribute with a reflexion on the expansion of the field of Design by the means of an analysis of the possibility of the insertion of the human body redesign within its boundaries. The main objective of this dissertation is to show the passibility of construction and, why not, deconstruction to which things, as well as the body itself, are subjected once existing under the aegis of culture, society and politics. In the post-modern moment that we live at, if it does exist, it is possible that the Designer, in an expanded sense, may be considered the maestro of these transformations. This dissertation also relies on a few events and theories to present how artists, scientists and philosophers comprehend and discuss these questions about the interferences practiced on the body, its possible obsolescence, the never ending quest for beauty and the quarrels between naturality and artificiality regarding the body. Thus, it concerns the possibility of construction of a theory of this activity, the Design, haven of a professional which can project objects as well as rethink his own structure. It is expected that this is not done for the sake of an ilusory and inexisting purity, but carrying on with his own designations, as men within our human condition.
