[Being a Jesuit, Schoonenberg was both scholastic and modern.  So, I am confident that he would be amused by what I am about to say, emerging, as it does, from the realm of possibility; the only realm that supports contradictions:

Why not correlate “noumena” to the “spontaneous order” and “phenomena” to “our evolved perception of design”?

Such a correlation would position Modern Philosophy as an unwitting mash of Friedrich von Hayek’s notion of “spontaneous order” (which we always misinterpret as design) and Stephen Gould’s notion of “exaptation then adaptation” (which is why we see design, even when we do not realize what we are doing).

The mash-up highlights the modern problem:  As soon as we start to see designs in the grand spontaneous order that emerges from everyone constructing according to their own designs, we are tempted to play God … or I should say … to act as the Devil, because sovereign interventions, even if well designed, cannot fully take into account the potential ways that the spontaneous order might adapt.]
