So my last round of musing was on the subject of “emptiness.” Connected to that idea is the concept of “fullness,” of “plenum.” I suspect that one of the primary failures of contemporary metaphysics is misunderstanding which is really which: that is to say, what is really full, and what is really empty. Here again, Whitehead’s process metaphysics offers us important insights. Because how we think of “fullness” – of a thing, a region of space, or whatever – is directly correlated to what we believe to be genuinely real. I argued earlier against the naïve concept of “empty” space, pointing out that not only is that space (according to physics) a broiling froth of micro events and virtual particles, but that it is also densely awash in relational connections to the rest of the universe. Adding to that earlier discussion, one could say that the space itself is a kind of “thing”: it is an event in its own right, it is a process of space relating itself to other spatial events. In this regard, Whitehead rejected the “material aether” that dominated astrophysical thought in the days between James Clerk Maxwell and Albert Einstein (the last quarter of the 19th C. to the first decade or two of the 20th), and argued instead for an “aether of events” as the dominating characteristic of space.
Without assuming – indeed, explicitly denying – any absolute sense of either “emptiness” or “fullness,” what sorts of relative conditions might lead us to characterize one sort of collection as generally more full, and another as comparatively more empty? Well, for that we need a notion of what it is that fills, hence that which is not there when things are empty. My argument is that what “fills” are events and relations. Continue reading
