This book presents a number of experimental projects in communication design as a symbolic and public practice. It proceeds from a critical position vis-à-vis the customary mediation of information―a position more necessary than ever, now that design operates so prominently in the entertaining and marketing spectacle organized by the neo-liberal world order as an instrument for the colonization of human existence. Unlike the classic form of visual communication, the dialogic approach is a connective model of visual rhetoric with a polemic nature and polyphonic visual form―a storytelling structure that seeks to reveal the opposing elements of the message and opts for active interpretation by the spectator.
This text has some important advice for designers on how to do our work more responsibly. But I couldn't summarize what it says because I had a hard time pushing my way through the academic jargon and forgot 95% of it as soon as I've read it. I suppose this book is out of my league. I hope someone will be able to explain these ideas in an accessible manner, so that us designers who are not social science majors can still benefit from them.
