If reality were not coherent through and through – if, that is to say, the Many things were not integral in some One – then there could be no world. There is a world, in which every one thing is completely coordinated to every other; so reality is coherent, and integral in and as some One.
Notice that finite creatures are incapable of the infinite calculation needed to achieve an integral coordination of things. The One in and as which things are integrated must then be itself infinite. It must furthermore be eternal; for, as constituting by itself the mundane forecondition and matrix of all the items that go to make up any worlds and their temporal orders, it must be prior to all such orders, and to their constituents. Such orders then, and all the Many, supervene upon that One.
In virtue of the perfect coordination of each item to every other, each atom is implicitly a system of all things. Trace the causal influences outward from any event x to their furthest extent, and you must thereby describe an account of all things, each of which has contributed to x. Were it otherwise, then actualities would not be really reflected in each other; and nor then could they be truly reflected in or by each other. If there be no fact of the matter in re the relations of things, then nor a fortiori can there be any truth of that matter.
Things could not then, any of them, mean anything. In that case, explanation, knowledge, understanding, representation, images, symbols, meaning, order, value would all be empty categories. So by the same token would their opposites, noise, chaos, disorder, etc.
Taking just one of those pairs of opposites, “order” and “disorder” between them cover all of reality. Everything whatsoever is more or less ordered; to be is to be ordered, more or less. If “order” and “disorder” were empty categories, then, there could not be any actual reality.
Either the One exists, forms and orders all things, or there is no such thing as things.
