Naturalism Purged of Metaphysical Fallacies
In an earlier post of some years ago I treated determinism from the perspective of why so many philosophers believe in determinism -- The Denial of Freedom as a Philosophical Problem -- so too I might frame the problem of naturalism purged of metaphysical fallacies as The Denial of Naturalism as a Philosophical Problem. And here I mean a strict naturalism, a rigorous naturalism, purged of all transcendent teleology, purpose, meaning, and value. This is not to deny that there is teleology, purpose, meaning and value in the world, only that transcendent teleology, purpose, meaning, and value are metaphysically incoherent.
The denial of naturalism as a philosophical problem is a failure to distinguish between philosophy purged of metaphysics (positivism, which in its post-positivist form converges upon naturalism) and naturalism purged of metaphysical fallacies. In other words, this is a conflation of bad philosophy with bad metaphysics, as once naturalism is purged of Metaphysical Fallacies it can be a perfectly respectable metaphysics -- but it is a metaphysical doctrine, and we ought not to dissimulate on that point.
While I want to avoid metaphysical fallacies and pernicious metaphysics as much as anyone, I have no objection to metaphysics per se. If metaphysics can be formulated in a philosophically respectable way, then that is all to the good as far as I am concerned. Post-positivist thought that hews closely to the traditional positivist line (even if not the name) keeps the flame alive by acknowledging the legitimacy of metaphysics in principle, but rejecting every actual attempt to formulate a metaphysics, which is always found to be wanting.
The positivist project closely resembles the phenomenological project, in its attempt to put into practice a a sweeping, rationalistic program without regard to the underlying history of the thought that is to be transformed by the programmatic approach. For Husserl this was the dream of a philosophy as a rigorous science; for the positivists this was the dream of science rigorously purged of metaphysics. But late in his life Husserl wrote, "The dream is over." Positivistically-conceived science ought also to be brought face-to-face with the harsh fact that the dream is over. Post-positivist thought ought to be exactly this, but it is not.
Of course, we still have survivals of metaphysical fallacies, and we still need to purge our thought of all manner of pernicious metaphysics. Even rigorously conceived and practiced naturalistic thought is subject to a thousand metaphysical ills, and being aware of the danger is usually not sufficient to safeguard against it.
One of the great fallacies of our time has been born of assimilating evolutionary thought to the tradition of the great chain of being, so that evolution itself becomes the temporalization of the great chain of being (scala naturae). In scientific terms, we know that evolution is a mechanism that acts without looking ahead, that it is a branching bush and not a ladder of ascent. All metaphysical fallacies to the contrary have been pointed out countless times by many biologists. We need to go beyond the recounting of scientific fallacies, however, and engage with the metaphysical fallacies, and the metaphysical fallacy in conflating evolution with the great chain of being is that evolution is the mechanism by which all possibilities are eventually actualized, i.e., the principle of plenitude.
This is but one example among countless possible examples, but it is an instructive example. Even today, several hundred years beyond the scientific revolution, it is arguable that the idea of the great chain of being is more easily comprehensible than that of natural selection; our evolutionary psychology has been unaffected by the scientific revolution, so that the business of purging our metaphysical fallacies is stubbornly counter-intuitive. Evolution has produced a brain that is incredulous in the face of evolution. (This is probably the ultimate source of Plantinga’s evolutionary argument against naturalism.)
Since unadorned naturalism is apparently too appalling to contemplate, instead we get naturalism with the accretion of human desires and wishes, which make it possible for naturalism to serve as a surrogate for more traditional beliefs -- beliefs that inherited considerable mystical and mythological baggage and so served a social function in mediating between the ordinary business of life and human experiences not easily assimilated to ordinary experience.
