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.
Contemporary architects are, however, increasingly engaging with ornamentation. The zenith was Grayson Perry and Charles Holland of FAT’s fairytale House for Essex (p64), but it does not serve as an indicator because the involvement of an artist has allowed an enhanced engagement with ornament until it surpasses mere decoration and becomes embodied in the architecture in a way that architects do not allow themselves to do. Think of FAT’s old work: the ornament is all contained within a surface - a facade - which allowed them to separate out the (Modernist) architecture from the (kitsch) superficiality of the elevation. Like Venturi before them, their ornament allowed them to have their ornamentally iced cake - and eat the Minimal Modernist sponge underneath.
