This work is the result of estrangement with regard to denial discourses of the form in Design, originated from the design field and from the observations of the recurrence of two factors in its constitutive pathway (considering the Western classical chronology): the discussions about the form and the form itself. The objective is to identify a possible network of concepts and factors that guide the actual form in design and establish a critical thought in order to strengthen a reflexive path to the understanding of this field, through what is the most concrete and resistant in design: the form - understood in this work as visual appearance, exterior aspect of an artificial materiality (built by men) as a result of a process (of configuration) that considers many (objective and subjective) aspects. For this, an examination of arguments - enunciation of critical and configurative agents of the material environment (architecture, arts, emphasis on design) that sustained, validated or defamed the formal production in design - is done. The temporal linearity supports the organization of narrative and leads the exposure of enunciations, but not in a rigid or imposed manner, as they can be moved from their time, approximated to others, by ways of thinking the form, and are examined regarding the theoretical tradition (hypotheses, concepts and assumptions), also considering the cultural, social and environmental contexts where they meet their legitimacy (or not). Theorists’ criticism, analysis and arguments (regardless the time) about the content of the enunciations mentioned here also constitute the work and support the reflection on the treatment given to the form.
