For Plato and many medieval philosophers, imagination was construed primarily as a mimetic act of mirroring, representing, copying. This approach was often associated with deceit and illusion, with confounding original realities with secondary substitutes. By contrast, for Kant and the romantics—including German idealists and existentialists like Sartre—imagination was hailed as a productive force in its own right, the source of all true meaning and value.
Bachelard resisted both extremes. For him, imagination was at once receptive and creative—an acoustic of listening and an art of participation. The two functions, passive and active, were inseparable. The world itself dreams, he said, and we help give it voice.
Is there positive value to recognizing an invisible Design Concept as a real entity in design conversations? I think so.
First, great designs have conceptual integrity—unity, economy, clarity. They not only work, they delight, as Vitruvius first articulated. We use terms such as elegant, clean, beautiful to talk about bridges, sonatas, circuits, bicycles, computers, and iPhones. Recognizing the Design Concept as an entity helps us to seek its integrity in our own solo designs, to work together for it in team designs, and to teach it to our youth.
Second, talking frequently about the Design Concept as such vastly aids communication within a design team. Unity of concept is the goal; it is achieved only by much conversation.
Thus, moviemakers use storyboards to keep their design conversations focused on the Design Concept, rather than on implementation details.
