Before we knew that galaxies tend to form the familiar fractal shape, we perhaps should have rightly expected this from the persistence of this pattern in the parts of nature we do observe. Indeed, I’m curious if we will observe a fractal pattern in sub-atomic phenomena at some point in the future (or if we already have? any particle physicists stumbling upon this post?).
But more generally than speculations about the universality of the fractal form, it seems an obvious though oft-neglected fact (perhaps precisely because of its obvious nature) that in both our speculations about physical phenomena we have yet to see, and our descriptions and language employed of that we do see, our scientific vocabulary is restricted to borrowing from pre-existing terms. Thus, we speak of the brain ‘stem’, the ‘core’ of the galaxy, the ‘heart’ of this, the ‘edge’ of the universe, and so on.((I don’t wish to deny that science is immune to neologisms, but I suggest that all neologisms are either accidental or intentional combinations or corruptions or otherwise representations of existing terms.)) What else could we do?
Theology (particularly natural theology, as distinct from a theology of revelation) shares the same semantic limitations. Every bottom-up God-word (shall we say every ‘theologism‘?), attempting to speak of the unseen and ineffable, is borrowed from the world of the seen and effable. Thus, in Judeo/Christian Scripture (neither limited to, nor exempt from the language of natural theology), God is said to be a ‘rock’, a ‘fire’, a ‘woman in labour pains’, a ‘Father’, a ‘mother hen’, a ‘lion’, a ‘lamb’, a ‘land owner’, etc. What else could we do?
But of course, uniquely, Christian theology claims that the impenetrable veil of perception has been pierced from the other side. God not only sent an authoritative message or book about Godself, but, to quote (and admiringly negate) Forrest Gump, “God showed up.” And this revelation has both affirmed and transformed (even subverted) the former types and shadows. That which was unable to be described with words was the Word made flesh. ”Nobody has ever seen God, but the only begotten Son, in the bosom of the Father, has made him known”, wrote John the seer (John 1:18). God is not just ‘like’, but was active, present and revealed as a self-giving, dying, rising man. The nakedly anthropocentric – yet still universal – Lord of All. In scientific terms, this would be the parallel (not ‘equivalent’) of an extra-cosmological entity (indeed if there be such a thing) entering our cosmos, our Milky Way, our solar system, our planet, our research institutions, and in a Mount-Sinai-like moment, engraving the equations down as the cosmologists shrunk back in a mixture of reverence and fear.
