It may be noted at this juncture that a Weltanschauung based upon physics cannot but be evolutionist to the core: for once authentic wholeness has become de facto inconceivable, it needs to be replaced by a pseudo-wholeness which reduces to the sum of its parts. And needless to say, the only way such a pseudo-wholeness can conceivably emerge is by an aggregation of its constituents. Moreover, inasmuch as such a pseudo-wholeness exemplifies no model or archetype, its formation cannot be in any sense “directed,” and reduces therefore basically to a random process. In a word, Darwinian evolution is essentially the one and only means by which plant and animal forms could conceivably originate in a world answering to the conceptions of physics.
