The space of the in-between is that which is not a space, a space without boundaries of its own, which takes on and receives itself, its form, from the outside, which is not its outside (this would imply that it has a form) but whose form is the outside of the identity, not just of an other (for that would reduce the in-between to the role of object, not of space) but of others, whose relations of positivity define, by default, the space that is constituted as in-between.
The space of the in-between is the locus for social, cultural, and natural transformations: it is not simply a convenient space for movements and realignments but in fact is the only place – the place around identities, between identities – where becoming, openness to futurity, outstrips the conservational impetus to retain cohesion and unity….E.Grosz, ‘Architecture form the Outside‘
