In this issue, Andrea Branzi, Ugo La Pietra and Franco Raggi look back, to talk about what it means to be radical, today and yesterday. The political and social role of design is addressed by another great protagonist, Gaetano Pesce, who reiterates his long-term conviction: design should reflect its time, speak to diversity, representing the incoherence that permits experimentation. It has to trigger a debate capable of generating a confrontation of values.
