This academic book pursues a sociological and corporeal-phenomenological positioning of architectural sociology research. Using comparative research in two libraries, it exemplifies how an architectural sociology grounded in corporeal-phenomenological theory and empirical work can be expressed; how corporeal-phenomenological-sociological methods can be applied, for which research questions they are suitable, and which substantive fields of knowledge, in the sense of corporeal processes of understanding, are thereby opened up. The aim of the corporeal-phenomenological-sociological study is to methodically break open the supposedly silent dimension in the relationship between humans and architecture; to bring the corporeal, sensory, and semi-objective elements of this relationship to ‘speak’ through verbal and visual material, thus enabling a cultural-sociological analysis of corporeal architectural experiences in the Stadtbibliothek am Mailänder Platz in Stuttgart and the Old Library of Trinity College Dublin. Based on the substantive findings of the empirical study, the paper concludes with a forward-looking proposal for how the mode of appearance of architecture can be conceptually grasped, understood, and (in the future) thought about. The developed direction of gaze opens up a space of possibility for understanding architecture as a transitive, fleeting, and ephemeral medium of communication and for doing justice to the diverse forms of perception as felt-bodily communication in the relationship between humans and architecture.
