Using empathy, as established by the Vienna School of Art History, complemented by insights on how the mind processes visual stimuli, as demonstrated by late 19th-century psychologists and art theorists, this book puts forward an innovative interpretative method of decoding the forms and spaces of Modern buildings. It proposes that Modern architecture is too diverse to be reduced to a few common formal or ornamental features. Instead, by relying on the viewer’s innate psycho-physiological perceptive abilities, the sensual and intuitive understandings of composition, form, and space are emphasized.
