No one knows what matter is. Scientific theory provides reasonable hypotheses, and perhaps ultimate matter boils down to circular wiggles of empty space. Space cannot be devoid of properties if it is capable of form, but that’s not the point. And what about the ambient pressure of the bang? Is it possible that like creatures in the depths of some cosmic ocean we have our being in an environment of intense pressure that we have no way of detecting because it is impenetrably ubiquitous? Whatever the yet undiscovered facts of the matter may be, we can say for sure that a haze of subatomic light-speed behavior is responsible for the plodding world of fishes and loaves in which we find ourselves.
Stacks of atoms. Everywhere we look we find mere stacks of atoms in those careless arrangements made inevitable as individual atoms attempt to fill outer electron shields by sharing electrons with some amenable fellow atom. These liaisons are more or less enduring according to the mutual benefit derived, and it is a simple flux of inevitability that gives us this or that molecular configuration. The mechanics of these goings on are so well understood that we now have huge factories that do nothing more (or less) than stack molecules to be pilled or bagged or boxed, and then shipped off to do their inevitable fluxing out there somewhere for the alleged benefit of all mankind. We know a lot about molecules. They are mere stacks of atoms.
But why then should a mere stack of atoms possess conscious awareness? And speaking of conscious awareness what is the nature of, say, sight? The vision of the forest that occurs in this mind as I look out through the forest has a real existence. What is the nature of its exsistence? Some have said that the immediate experience of a given mind is the only thing that it can claim with total certainty to be real. What's with that? But I digress. The question is: why should a mere stack of atoms possess conscious awareness (let alone life)? It has to be something about the way the atoms are stacked, because other than that we are looking at perfectly ordinary molecules. Perhaps it is a field phenomenon created by the behavior patterns of the shared electrons that hold the DNA molecule together. No one knows, but it is apparent that life must somehow inhere in matter.
Plant-animal distinctions start at the level of single-celled life forms. And though these distinctions are sometimes hazy there exist unambiguous examples of what seems to be volition on the part of one-celled creatures. I suppose we could describe the amoeba’s “catch and consume” behavior as a tropism thing or some such; but the fact remains it does not notice, pursue, and consume it’s prey by accident. Primitive nerve systems seem to be the facilitators of awareness and not the progenitors. Fast forward to the human brain.
