Didier Debaise, "What is Relational Thinking?" from Inflexions (no. 5, 2012) and Didier Debaise, "A Philosophy of Interstices: Thinking Subjects and Societies from Whitehead's Philosophy" from Subjectivity (no. 6, 2013). The latter article's abstract is worth posting below. I see resonance with metaxological ontology, e.g. William Desmond, Robert Corrington, Robert Neville, i.e. the American process ontologists. The space or interstice, the space of the "in-between," usually thought of as something empty or secondary with no importance to the identity of things, actually can itself through a negative activity be involved in the process of how "selves" come to be, especially within environments where this "in-between" is said to be absent or "not." Rather, as Debaise points, it is quite the opposite:
The notion of interstice appears in philosophy as something empty, an in-between, with no importance in the constitution of things. I argue, on the contrary, that the concept can be retaken in a new interpretation of living subjects as a main category to interpret the spatial and temporal dimensions of a subject.
