Life's Origin: First Steps

When it comes to the origin of life, we seem able only to come up with two theoretical structures, possibly a third if we combine the other two. One is that life emerges from matter spontaneously by chance. The other is that God creates the living by a special act. The combination, favored in Catholicism, for example, is to picture God creating the cosmos in such a way that life is already present in it; thus at the appointed time, life will emerge from matter. Here the absolute sway of chance is mitigated if not entirely removed; it is replaced at the crucial point by an intention hidden in the very structure of physical reality.

The third solution is both elegant and subtle. It leaves science to follow its naturalistic methodology wherever it might lead without the embarrassments that the intrusive correction of Galileo occasioned for the Church. At the same time it preserves the ultimate ground of creation as an act of God.

When I look at this solution in more detail, however, it has a troubling aspect. If life is hidden somewhere inside of matter, its emergence is a change in degree rather than in kind, and I’m persuaded that life is different in kind. My reason is that life displays teleology, thus it displays purpose. The most obvious evidence of this is reproduction. It is the continuation of a very complex arrangement of matter, what might be called an extremely complex form, by an intricate step-wise method, a whole long chain of intricate processes. We do not encounter anything resembling it in inorganic nature. We do encounter various examples of simple structural changes in response to stimuli, thus the formation of crystalline forms, e.g., snowflakes, but we don’t find anything at that level in which a necessary chain of formations takes place and must take place for the end result to emerge.

Purpose is, strictly speaking, associated only with agency. I grant you that this is an intuitive finding. It takes a special effort to deny that agency is present in living entities. It is observable. To explain it away mechanistically is always possible when the entity manifests in physical form. The physical expression of agency will take place using mechanical means. But to assign agency, purpose, strictly to mechanism requires that we willfully ignore that which we really see and feel. It is literally impossible to deny that we feel purpose. It's presumptuous on our part to deny the same feeling to dogs, to plants, indeed even to cells. What we observe is a difference in awareness, not a difference in end-seeking tendency. This is the same-old, same-old battle between two ways of perceiving. I don’t want to waste time on it. But the point I’m after here is that the third solution, given above, namely that life is embedded in the cosmic whole from the start, that it permeates matter so that, in the ripeness of time, it may emerge, that solution doesn’t please me. Even when offered by Catholic thinkers, it still reminds me of panpsychism.

There is a version of this mode of thought that I find much less troubling. It is that two (or at least two) orders of reality are present in the cosmos. David Bohm, the physicist, formulated this conception as the presence in the Whole of a conditioned and an unconditioned order. You can find this idea in Bohm’s Wholeness and the Implicate Order, Routledge, 1996. Another way to put this is that an order of agencies or souls exists and so does an order of matter. There may be many other mansions in the Lord’s house as well, but here I’m pondering two. This sort of concept can be imagined as two orders that coexist and possibly also interpenetrate—and under certain circumstances the unconditioned order may, in fact, act upon the conditioned order where circumstances permit such interactions. Both, however, exist independently. As for their origin, my view is simply that if agency exists at all, its origin must be God. The unconditioned order, of course, has both consciousness and freedom; that freedom is clearly delimited, as we see from our circumstances. It isn’t, in us, omnipotence. But it has freedom as the order of matter does not.

The difference I see in this position, call it 3A for convenience, is that it keeps separate what are, in my view, two orders, separate in kind, not one rising from the other. I can thus imagine a community of spirits becoming entangled in matter, seduced by it, as it were, and, over long periods of time, building a strange intermediate world of incarnation just because it’s possible. In my science-fiction role I’ve named this chemical civilization. Thus all of life is a construct by spiritual agencies, working on their own. They don’t originate life—because they are life. But they cause it to manifest in matter, where it does not properly belong. This notion first arose in me when studying biology as a grown man with three children. It has long intrigued me because it fits in many ways that which I see displayed in biology. What it requires is that we also imagine the possibility of many grades of consciousness—upward and down. We find no difficulty imagining higher beings—we even have names form them: angels, whole choirs of them. We find it difficult to imagine spirits operating in vast choirs of their own at levels way lower than ours.

This conceptualization demands a cosmology different from the Aristotelian/Thomistic which builds its hierarchy from unformed matter to absolute act. Thus I’m challenging a tradition vastly more grown-up than I am. But I find that hierarchy difficult in spots. Since it goes on into orders of spirit, ever higher, it does not seem to have a proper justification for matter—unless it is to make sense of man. But what if man is just trespassing on matter? What if original sin has another meaning yet? What if matter has a different explanation?

Obviously there is more to say here, but these posts shouldn’t get too long.
