From Vision in Motion, László Moholy-Nagy, Chicago 1947:
Design has many connotations. It is the organization of materials and processes in the most productive, economic way, in a harmonious balance of all elements necessary for a certain function. It is not a matter of façade, of mere external appearance; rather it is the essence of products and institutions, penetrating and comprehensive. Designing is a complex and intricate task. It is integration of technological, social and economic requirements, biological necessities, and the psychophysical effects of materials, shape, color, volume, and space: thinking in relationships. The designer must see the periphery as well as the core, the immediate and the ultimate, at least in the biological sense. He must anchor his special job in the complex whole. The designer must be trained not only in the use of materials and various skills, but also in appreciation of organic functions and planning. He must know that design is indivisible, that the internal and external characteristics of a dish, a chair, a table, a machine, painting, sculpture are not to be separated. The idea of design and the profession of the designer has to be transformed from the notion of a specialist function into a generally valid attitude of resourcefulness and inventiveness which allows projects to be seen not in isolation but in relationship with the need of the individual and the community. One cannot simply lift out any subject matter from the complexity of life and try to handle it as an independent unit.
There is design in organization of emotional experiences, in family life, in labor relations, in city planning, in working together as civilized human beings. Ultimately all problems of design merge into one great problem: ‘design for life’. In a healthy society this design for life will encourage every profession and vocation to play its part since the degree of relatedness in all their work gives to any civilization its quality. This implies that it is desirable that everyone should solve his special task with the wide scope of a true “designer” with the new urge to integrated relationships. It further implies that there is no hierarchy of the arts, painting photography, music, poetry, sculpture, architecture, nor of any other fields such as industrial design. They are equally valid departures toward the fusion of function and content in ‘design.’
