A collection of insights, a series of hypotheses about the transversality and interdisciplinarity that characterize the process of creating design. A succession of micro-narratives that take reality as a source of inspiration. The evolution of materials and techniques, art and design, its authors and their works, aspects of form and type, of history and anthropology, psychological and social elements, all come together in a succession of consequential and hence inseparable reflections on the 'quantum sufficit' to recount the complexity of designing in our times.
