" Space, for Lefebvre, does not exist prior to the things that occupy and fill it. Space is, indeed, produced, offering three dialectically related processes, three different aspects of space.
On the one hand, Schmidt explains the triad of spatial practice: representation of space and spaces of representation.
On the other hand. there are concepts of percieved, concieved and lived space.
This double helix emphasizes a dual approach one which is at once phenomenological and linguistic."
