Theodicy and Determinism: The Folly of Leibniz's "Best Possible World"


Theodicy: In Christian theology,any attempt to reconcile the occurrence of evil and/or suffering in the world with the traditional theistic attributes of omnibenevolence (i.e."all-loving"), omniscience (i.e. "all-knowledge"), and omnipotence (i.e. "all-power"). 
The theodicy conundrum is typically set up as a "best possible worlds" dilemma: of all possible worlds that could have been created, why would an all-loving, all-knowing, and all-powerful God create a world in which evil and suffering exist? Why did God create the circumstances that would allow Adam to sin? These questions, the stuff of anti-theist rejoinders, have been the perennial bane of Christian theology for time immemorial.

In his Essays on the Goodness of God, the Freedom of Man and the Origin of Evil, the German mathematician and philosopher, Gottfried Leibniz (1646-1716), proposed a rather ingenious solution to the best possible worlds dilemma. Leibniz agreed that a world created by an all-loving, all-knowing, and all-powerful God would necessarily have to be the best of all possible worlds, and so he believed the world to be! His ingenuity was seen in his novel solution to the problem of evil. The presence of evil and suffering in the world, so he argued, was necessary for the realization of the highest possible good. In other words, God was an "optimizer" of sorts, allowing evil in order to optimize the degree of goodness manifested in the world. A world devoid of evil, while perhaps paradisaical, could never know the higher virtues characteristic of a world in which evil existed -- virtues such as fidelity, sacrifice, bravery, courage, altruism and the like. These can only be known in a world like ours, that is, the best of all possible worlds. Leibniz not only believed that his solution resolved the theodicy conundrum, he also saw it as the best proof for Christian theism.

Naturally, Leibniz's solution produced many critics. The celebrated atheist, Voltaire, would opine that the amount of suffering actually seen in the world could in no way justify Leibniz's optimism. Voltaire's retort had the force of the preponderance of human experience behind it, at least for those who did not turn a blind eye towards the ravages of poverty, war and disease. Yet little did Voltaire know in his day that such societal evils were merely the tip of the iceberg. Modern science, particularly the insights of evolutionary theory, would go on to reveal a world where the formation and exhaustion of stars, the energy demands of biological life forms, tooth-and-claw competition, suffering, pain, death, biological dead-ends, mass extinctions and the like not only existed, but were in fact the rule: the metanarrative of "the world of the universe that is." In fact, the "higher virtues" of Leibniz's best possible world would not emerge until eons and eons of senseless, ravenous and cannibalistic processes had finally produced -- in a tiny, unremarkable recess of the universe -- moral creatures such as ourselves. Relatively speaking, such virtues appear to be a meaningless aberration in a world defined by "death"; illusions born of evolutionary adaptations that our species happened to find useful in the competition of the survival of the fittest.

Voltaire's retort certainly had subjective and emotive force behind it, but it would still be possible to  argue that the "highest possible good" was ultimately a valuation judgment best left to God, the judge of all things. Indeed, the real weakness of Leibniz's solution was not his "optimizing of the good" explanation for the existence of evil, but rather the implicit determinism that the "best possible worlds" dilemma assumes from the outset. If, as the dilemma contends, an all-loving, all-knowing, and all-powerful God must create a world in which the most optimal conditions exist for the realization of the highest possible good, then all future reality must in some sense already exist in the mind of God. Simply put, from eternity past, God would have had to will the creation of a world in which he infallibly knew all that would take place, and could not have chosen to create any other!

Leibniz was not the first to fall unwittingly into the trap of determinism. Christian theology had been entangled in determinism since the days of Origen. Indeed, even today most Christians are little aware of how pervasive determinism is and how it affects their theistic beliefs, often in self-contradictory ways. This is particularly the case with the traditional understandings of omnibenevolence, omniscience, and omnipotence. A God who is bound by his "all-loving" character to create the "best possible world" can hardly be said to be "all-powerful." The very concept of "best possible" becomes nonsensical, since, in the infallible foreknowledge of God, only one possibility exists!

Determinism has created more problems than necessary, particularly in the perennial preoccupation of Christian theologians to absolve God as the cause of evil and suffering. This is typically done by distinguishing between the "two wills" of God, namely, the causative and the permissive. So it is argued that to permit evil is not the same thing as causing it; hence, God cannot be said to be the author of evil if he merely permits it to exist (its causation being attributed to other moral agents, like fallen angels and Adam).

However, the knowledge of future actions and the decree to create in view of them amounts to the same net result: soft determinism is still determinism. Even if (in good Molinist fashion) the free agency of moral beings is built into the system to account for the causation of evil (i.e. sin, suffering, etc.), this could only be admitted as a means towards a divinely appointed end. In actuality, free agency would simply not exist in such a world; only the appearance of it. One may choose chocolate over vanilla, but if that choice were determined ahead of time (insofar as God chose to create a world in which all future actions were infallibly foreknown), then no other choice would ever be possible. In another scenario, one could just as well "choose" to commit murder, and that choice would be just as certain from an eternal standpoint. In the final analysis, it is impossible to exonerate God entirely from evil in any deterministic system.

Natural (s)Election, Part Two: Anthropocentrism, Myopia, and the Uniqueness of Humanity


Read Part One.

The acceptance of evolution by theologians is inevitable. Why say this? Because it must be. The Christian faith cannot hope to speak meaningfully to the world if those responsible for the articulation of that faith cannot see clearly to accept what has been established by science beyond all reasonable doubt, and to adapt accordingly. This assertion, however, should not be misconstrued as a plea to theology to accommodate a foreign idea or a conflicting set of values or principles in some vain attempt to keep Christianity relevant. Rather if Christianity is true then it will be found to be consistent with all other truth, and prove sufficient in its ability to adapt its articulation to our expanding understanding of the world around us. Nevertheless, the theologian should be prepared for the radical shift that must take place in his or her perspective; for, upon acceptance, the theologian will have to account for the drama of evolution, not only as natural occurrence, but for what it truly is: the history of redemption itself.

Part One presented Anthropocentrism as a necessary presupposition in theology, albeit an illusory one. It is necessary because any coherent account of divine disclosure to human experience must be interpreted from within human experience. It is illusory when it fails to account for the vast array of possibilities that the "freedom-to-become" (creatio continua) implies, inevitably leading to an anthropological exceptionalism that will ring less and less "true" with each new discovery. This is both a danger and an opportunity for the theologian.

So it was, not too long ago, that theologians regarded humankind as the primary or even the exclusive object of redemption. This was quite understandable within an ancient framework that saw the rest of the cosmos as a secondary consideration at best -- "mankind's" habitation. After the Fall, the cosmos became the arena of judgment for humanity, a place hardship, perils, floods, famines, disease and eventually physical death. The state of death and decay being irreversible, it was easy for theologians to regard the physical universe as consigned to a hopeless destiny, at least on this side of the resurrection.

Certainly, human beings shared this habitation with other living things -- plants and animals -- but "mankind" alone was seen as the "image-bearer" of God. All other creatures existed (at least originally) for the benefit and enjoyment of human beings, and later for their judgment. Like a parent who cares that a child takes proper care of his toys, cleans his room, and feeds the dog (not for the sake of these things as much as for the betterment of the child) so traditional theology saw God as the divine parent providing in creation all things needed to sustain human beings, to teach them obedience, and to bring their lives to fulfillment. Thus the value of the cosmos was seen as relative to humankind's use, discipline, and pleasure. That God would show anything more than a concern for the proper stewardship of creation was hardly a consideration ever taken up by theology.

However, Copernicus shattered this perspective long ago. While many theologians have certainly failed to appreciate fully the vastness of the universe that Copernicus bequeathed to us, Darwin's breakthrough insight of natural selection, once embraced by the theologian, will certainly prove to be the undoing of anthropological exceptionalism. Simply put, the scientific investigation of our universe, from the sub-atomic to the astrophysical to the realm of biological processes, has wrought nothing less than the relativization of humanity's place in the cosmos.

No longer can the theologian afford to regard anthropos as the sole object of God's redemptive love, the exclusive image-bearer, or the center of the created order. If natural selection means anything in theology it means that the phenomenological emergence of anthropos in our small corner of the universe is the creative response of a cosmos imbued by the loving call of its Creator towards greater and greater complexity in the exercise of its freedom-to-become. Thus, the entirety of the cosmos, not just one minuscule part of it, must be considered in terms of the imago Dei (or rather as potentia imaginem Dei).

Indeed, we have emerged as imaginem Dei intellexit -- as the image of God realized. Yet anthropos considered in terms of an a priori goal or telos of the cosmos can no longer be taken as a theological presupposition. From a natural standpoint, we emerged from stochastic processes. From a theological standpoint, we are the ends for which God created the cosmos, but one possibility of myriad outcomes.

Is it any wonder then that many Christian religionists object so strongly to the notion of evolution by natural selection? The shift in perspective that is required by Darwin's breakthrough theory is regarded as too radical, too seismic in scope and extent for the "old time religion" to survive. It simply leaves no room for anthropological exceptionalism. Even the anthropocentrism that is readily admitted as a necessary theological presupposition is revealed as myopic. Perhaps such myopia can be excused when corrective lenses are not available. But once placed over our eyes the spectacles reveal a world in sudden relief that we are compelled either to accept or, in madness, to deny. Yet, rarely, do religionists take on the full view at once. In matters of religion, first reactions are typically irrational. New perspectives are initially denied, suppressed, and all-too-readily explained away or selectively accommodated when no other recourse remains.

But fear not! The faith as revealed has demonstrated time and time again to be more than sufficient for the task, even during seismic shifts of perspective. If, as we believe, the Christian faith is a divinely revealed faith, then it is true. If true, then it will agree with all else that is true no matter where such truth is found (e.g. in the "book of nature"). It stands to reason then that the relativization of humanity foisted upon us by the acceptance of natural selection (not to mention the vastness of the universe) serves the ends of theological truth by opening up a greater world to the theologian -- a greater realm of redemption to consider. All at once the entire cosmos becomes the object of God's elective grace, the receiver of the gift of incarnation, the subject of theosis.

Yet this is not to say that humanity's place, while no longer exclusive in principle, is no longer special or unique. Certainly it is both special and unique in our small corner of the cosmos. Even if life with consciousness very much like our own existed elsewhere in the universe, the distances (for us) are far too great to be meaningful; and while nothing precludes God "becoming flesh" in other contexts, and in ways appropriate to those contexts, this would be of no immediate concern to us. In the final analysis, and for the time being, we perhaps can still afford a vestige of our exceptionalism, if only for the impracticability of ever discovering such as ourselves in other corners of the "world of the universe that is."

Rehabilitating Pelagius: The Making of the West's Most Notorious "Heretic"


Perhaps no greater acrimony can be meted out in Christian debate than to accuse someone of "Pelagianism." Pelagius (354-418) was a popular ascetic whom most scholars accept was born somewhere in the British isles. Around 380 he moved to Rome where he took up writing and teaching about his ascetic practices. Around 405 he was exposed to some passages from Augustine's Confessions which provoked his first publicly-made objections to Augustine's views on predestination and grace, suggesting that such views were to blame for the moral laxity that he observed among Augustine's admirers in Rome. After the sack of Rome by Alaric in 410, Pelagius relocated for a short time to the city of Carthage where he had a brief, but memorable encounter with Augustine. Shortly thereafter the two adversaries began their famous literary debate.

Nowadays, it is generally conceded by scholars that Pelagius's notoriety in the Western Church owes at least as much to a misunderstanding and/or the misrepresentation of his views as it does to the ascendancy of Augustinianism in the West. The anti-Pelagian propositions of the Council Carthage (418) appear more to have been addressing Augustine's caricature of Pelagius's views and/or what the Council may have been led to believe were the logical implications of his views than they do an accurate account of what he actually taught. Among the propositions affirmed at Carthage (contra Pelagius) were:

1. That death came from sin and not from our physical nature;
2. That infants must be baptized to be cleansed from the guilt of Adam's original sin;
3. That justifying grace (infused not imputed) remits past sins and helps to avoid future ones;
4. That grace imparts both the strength and the will to act out God's commandments;
5. That no good works are possible without divine grace;
6. That saints confess to be sinners because they truly are;
7. That children dying without baptism are excluded from eternal life.

Amazingly, a contemporary assessment of at least some of these propositions is enough to make many Christians cringe with discomfort, even in contexts where the spirit of Augustinianism runs deep. Indeed, it is a testimony to Augustine's polemical skills and prolific output during this period that he is remembered as the premier patristic voice in the West, despite that fact that some of his views have either been largely qualified or quietly discarded, which makes it even more ironic that Pelagius is reckoned to be one of the church's most despicable heretics.

Naturally, Pelagius's literary output was suppressed after his condemnation and is thus no longer extant. Yet what does remain of his work demonstrates that many of the views attributed to him he in fact did not hold. For instance, it turns out that Pelagius actually did believe that baptism was necessary for the salvation of children, though he did not believe they were held accountable for Adam's sin; he did in fact believe that saints were sinners, though he also held that some saints had successfully stopped sinning (a common enough belief in his day, especially among ascetics); and he did hold that grace was necessary for good works and to please God, though he did not hold that such grace cancelled out the freedom of the will. Indeed, it appears that Pelagius even held to a form of prevenient grace that was necessary to draw a person to salvation, though obviously such grace was resistible.

Where Pelagius fell afoul of his great adversary Augustine was in his criticism of the latter's strict predestinarianism which, to Pelagius, seemed to suggest that human beings were mere automatons. Pelagius attributed this position to a residual "Manichaeism" in Augustine (recall that Augustine had been a Manichee), in which the flesh was considered utterly corrupt and evil and thus powerless to perform any works that could please God. In fact, all acts of the flesh were inherently sinful and worthy only of divine condemnation. Pelagius was appalled by what seemed to be the implication that human beings could be condemned for something they could not avoid (sin).

That Augustine did indeed retain something of his former Manichee views of human nature seems a fair assessment on Pelagius's part. But rather than base his pessimistic views of human nature in the Manichee mythos that the physical universe was not created by God at all, but rather by evil forces, Augustine found in his new Christian faith an explanation that seemed to uphold the doctrine of God as Creator of all things while at the same time exonerating God from being the author of sin. This was, of course, the story of the Fall of Adam in the Book of Genesis, especially as interpreted by Paul in his Letter to the Romans (chapter 5). Augustine reckoned that Adam's first sin was both the root of all evil and corruption in the world as well as the cause of mortality. As nothing remained of meritorious value in human nature after the Fall, salvation would necessarily be regarded as being of pure grace, in which the human will or volition could play only a passive role and only after it had first been regenerated by grace. Since it was obvious to Augustine that not all are redeemed, it must be the case that those who are redeemed are also predestined by God to salvation.

This would explain why Pelagius's positive views of the human will would be characterized by Augustine as amounting to the outright denial of such things as the necessity of grace in salvation, the universality of human sin, and even the need of baptism for the salvation of children. For Augustine, to deny the utter depravity of human beings (the foundation of his absolute view of predestination) was to deny the entirety of the catholic faith. Thus condemning Pelagius on these lesser matters (whether or not he had actually denied them) made him out to be the foe of long-cherished Christian doctrine and practice and thus someone who was eminently more condemnable by councils; whereas to challenge Pelagius's orthodoxy on the greater matter of the nature of predestination would have been to wage a war in an area that was not yet (nor ever would be) settled doctrine.

The background and issues raised in this ancient debate have never been more important than they are today, if only because of the near total monopoly that Augustinianism has had over western theology over the last sixteen centuries. This has not been without its consequences in the development of western theology, particularly in our own day when theologians are compelled to deal with the challenges presented by the discoveries of modern science, especially human origins. Indeed, rehabilitating Pelagius, at least in part, may go a long way to dismantle assumptions that have kept theologians from adequately facing these challenges.

For instance, given what we now know to be the origin of the human species through the process of evolution via natural selection, contemporary theologians can hardly take for granted the Augustinian notion that "death came from sin" and not from our physical nature; nor can it be seriously entertained that the "flesh," that is our "sin nature," derives from some supposed "first" or "original" sinful act that took place in an Edenic paradise. Simply put, the theological-narrative that Augustine had constructed from the Book of Genesis no longer suffices as an explanation for the origin of sin, the onset of mortality, or the need for grace, at least not in any reified or historical sense. Once this is admitted, even Augustine's doctrine of predestination loses much of its raison d'etre and begins to look suspiciously more and more like the fatalism that Pelagius contended that it was.

Natural (s)Election, Part One: Incarnation & Evolution

Note: The "s" is intended to be silent.



Anthropocentrism can be defined as the assessment of reality through an exclusively human perspective. At best it appears to be an illusory assessment, relativized as it is in the age of science by what we now know of the vastness of the universe, the diversity of life, and the indeterminacy of natural processes. Yet it is not what we actually know about the cosmos that so relativizes our anthropocentric impulses as much as it is the profound sense of what we do not know.

In theology, however, anthropocentrism is a necessary presupposition. Any coherent account of divine disclosure to human experience within human experience must be interpreted from human experience. While some may balk at this assertion on the grounds that the Christian assessment of reality is grounded in Christ (thus, "Christocentrism") the fact remains that the significance of the Christ-event lies in the incarnation. So the fourth gospel says, "The Logos became flesh and dwelt among us." Hence, theological anthropocentrism is Christocentrism, and vice versa.

Yet, in view of science, the theological task must take great care lest its presupposition of theological anthropocentrism degrades into crass "anthropological exceptionalism," wherein lies the failure of much of what passes for religious discourse to speak meaningfully to a scientific age. For the purposes of this essay (and the one that follows), anthropological exceptionalism can be defined as the belief that humanity has a unique call, a unique place, a unique destiny which the rest of the cosmos either has no share in or has a share in only in respect of human mediation or administration.

As argued in "Imago Dei, Divine Risk & the Freedom to Become," nothing precludes the emergence of life elsewhere in the universe, even sentient, conscious and intelligent life. From a theistic-evolutionary perspective, not only can we "hardly afford to reify the Edenic myth of the earth as a place in the universe specially prepared to await the arrival of our species," but we can hardly claim, as a theological necessity, that there is anything exceptional about our peculiar species of terrestrially-bound hominid that would preclude the possibility of multiple instances of divine incarnation elsewhere in the "world of the universe that is."

While the human species may indeed be considered unique among all known living things, and thus extraordinary in that regard, the theistic-evolutionist must regard, in principle, the potential to be "self-aware" -- conscious, intelligent, and even moral -- as instilled in the created order itself, endowed by its Creator who draws all of creation into the divine life (defined in another essay in terms of imago Dei in potentia). Indeed, nothing precludes the possibility of self-awareness emerging elsewhere in the universe, perhaps many times over. It just so happens to have happened here on planet earth, through the evolutionary, adaptive process known as "natural selection"; and it just so happens to have been actualized in anthropos -- the universe become both "self-aware" and aware of its Creator, and, as a consequence, aware (at least partially) of the purpose for its creation: theosis.

It would not, therefore, be unreasonable (from a theistic-evolutionary perspective) to consider natural selection as the process that brings about the necessary conditions of and context for incarnation. This would mean then that incarnation should not be regarded as a divine afterthought or contingency plan in view of the Fall, but rather as the divinely-purposed natural outcome of creation, its pinnacle, its final end, its telos.

Seven Views on Creation, Evolution, and Divine Intervention


1. Young Earth Creationism: Supernatural explanations account for the origin of the universe, the apparent age of the earth and its geological features (e.g. catastrophic worldwide flood), the origin of life, speciation ("each according to its kind"), the mass extinction of species (again, the flood), biological adaptations (so-called "micro-evolution"), and the direct, special creation of humanity.

2. Old Earth Creationism: Naturalistic explanations account for the natural history of the universe (e.g. the "Big Bang") and all non-biological systems, the geological age of the earth, and the time spans necessary for the emergence, flourishing and extinction of many species (as recorded in the fossil record). However, supernatural intervention is necessary to account for the origin of life (in different epochs), direct speciation ("each according to its kind"), biological adaptations (so-called "micro-evolution"), and the direct, special creation of humanity; common descent of the species is specifically denied.

3. Intelligent Design (M. Behe, 1996-version): Naturalistic explanations suffice to account for the natural history of the universe and all non-biological systems, including the earth and its features, and the time spans necessary for the emergence, flourishing and extinction of many species (as recorded in the fossil record). However, supernatural intervention is still necessary to account for the origin of life, the "irreducibly complex" adaptations to DNA that account for speciation (common descent being conceded), and the eventual emergence of humanity. In principle, supernatural intervention is detectable.

4. Intelligent Design (M. Behe, 2006-version): Added to the position above is the idea that much (most? all?) of the information necessary for the origin of life, speciation, and the eventual emergence of humanity was "front-loaded" or programmed into the Big Bang. In principle, these supernatural "fingerprints" are detectable in the irreducible complexity of biological systems.

5. Theistic Evolution -- "Interventionist" (strong version): Naturalistic explanations suffice to account for the natural history of the universe and all physical systems, both non-biological and biological, including the earth and all its features, the origin of life and biodiversity through evolutionary processes (in which common descent is emphatically affirmed), and the time spans necessary for the emergence, flourishing and extinction of many species (as recorded in the fossil record). Nonetheless, God imperceptibly directs the entire course of the universe to his appointed ends, including the emergence of humanity. Natural processes are only apparently random.

6. Theistic Evolution -- "Interventionist" (weak version): Same as above, though with God overseeing otherwise random processes and only directly intervening to ensure certain outcomes or results. In this way, God "nudges" or subtly "guides" the processes of evolution (perhaps on the quantum level) so as to ensure that the biological adaptations necessary for the emergence of that which would otherwise be improbable take place, e.g., that human beings would come about eventually. In principle, such intervention, as it remains within the limits of possible outcomes of otherwise random processes, is undetectable to scientific investigation.

7. Theistic Evolution -- "Kenotic": The cosmos was created fully ordered, hence, naturalistic explanations suffice to account for the natural history of the universe and all physical systems, both non-biological and biological, including the earth and all its features, the origin of life and biodiversity through evolutionary processes (in which common descent is emphatically affirmed), and the time spans necessary for the emergence, flourishing and extinction of many species (as recorded in the fossil record). Yet creation is an act of divine kenosis ("self-emptying"), wherein God "makes room" for something other than the divine-self (i.e. the cosmos or universe), gifting the universe with both the "freedom-to-be" as well as the "freedom-to-become." In principle this means that natural processes, including biological systems, are contingent (i.e. random), yet the Creator, is not an "absent deity." Rather God interpenetrates the entire cosmos, animating it, sustaining its order and natural processes, and calling and drawing it toward greater and greater complexity, eventually manifesting in the emergence of life, consciousness, intelligence, moral awareness, etc. -- the imago Dei.

Humpty Dumpty and The Idols of Our Thinking


Based on a recent conversation in another forum:

Once upon a time I too was a "top-down thinker," vainly imagining that if my philosophical and theological reasonings were sound, locked-up, air-tight, and "correct," then everything else "down below" would conveniently fall into place, eventually anyway since I did not have all the answers yet. "Common sense be damned!" The Biblical Inerrantist I once was would never countenance the possibility of formal contradictions in the Bible; any discrepancy I could not explain was merely "apparent." The Creationist I once was would never tolerate any interpretation of the empirical evidence that suggested evolution by natural selection, because, of course, that would not have been consistent with my understanding of God as Creator. But what if the Bible did contain discrepancies? And what if evolution by natural selection did occur? These were questions I was afraid to ask, because my top-down world, like Humpty Dumpty, might have "had a great fall." It is a menacing enterprise, at first, to retrain oneself to be a "bottom-up thinker." We suddenly discover that all of our "top-down" loyalties are on trial, and that is a frightening notion for those of us who have been conditioned to place absolute trust in the idols of our thinking.

Paradise Imagined (Part Two): Toward an evolutionary account of Original Sin



See also: Paradise Imagined (Part One) and The Two Minds of Augustine.
[The story of the Fall] is the profoundest and richest expression of man's awareness of his existential estrangement and provides the scheme in which the transition from essence to existence can be treated. (Paul Tillich, Systematic Theology 2:31)
Until recent times, the traditional meta-narrative of Original Sin has been able to provide a sufficient answer to the origin of sin through its telling of the story of Adam's fall. Though somewhat at pains to explain why the Fall happened in the first place (i.e. beyond "sin-as-possibility," or, in Augustinian terms, "posse peccare"), the traditional meta-narrative nonetheless neatly explained every subsequent sinful act in human history as predicated on Adam's first sin and its consequent deleterious effects upon human nature. Thus sin becomes both inevitable and universal in Adam's progeny (who were now deemed non posse non peccare). However, with the decoding of the human genome, science has put the final nail in the coffin of monogenesis (i.e., human origins from an original couple), and with it the idea of Adam's sin as "causal event." Eden's story of "Paradise Lost" suddenly becomes the story of "Paradise Imagined." Genesis's epic etiology is recast as a mythic story of realization, not of how things had gone awry, but simply that they have. To borrow a phrase from Tillich, our ancient storytellers had "dreamed of innocence."

Thus, for the theistic-evolutionist, the origin of sin as event is no longer an issue of theological importance. Even if it were possible to determine the exact moment when the willful act of a common ancestor could be counted as sin, there would be no basis, either theological or ontological, to posit a causal connection between that supposed "original" sin and every subsequent sinful action in the history of the human species. Instead, the theistic-evolutionist seeks to explain the origination of sin as grounded in conditions that would not only make sin possible, but also inevitable; and, if inevitable, then universal as well.

So we must start with a consideration of divine creative activity, and in particular creatio continua with its divine gift of "becoming." If, as we have argued previously, the "freedom to become" means that the processes of an evolving universe are free, contingent, and undetermined on the physical level, then what does this "freedom to become" imply on the level of consciousness? What does indeterminacy look like in the actualized moral realm of this evolving universe? And in what ways do free moral agents experience or exhibit this "freedom to become"? These are the questions at the heart of a theistic-evolutionary account of Original Sin.

As a preliminary answer to these questions, we suggested in Theosis Interrupted that the indeterminacy and contingency of the cosmos take on new significance with the arrival of human consciousness, particularly in the corresponding emergence of the human faculty of volition, or "will." Simply put, human beings, considered as moral agents, are "free" to make moral choices; a "freedom" that includes the very real possibility of sin because it assumes "free will" as an essential human faculty (i.e., libertas voluntatis essentialis). Yet, as tidy as this explanation may be in explaining "sin-as-possibility," the universal aspect of sin (or "sin-as-inevitability") must be posited on different grounds; and therein lies the rub, for one must exonerate nature as the cause of sin (else fall into Gnosticism) while at the same time avoiding the suggestion that God is the author of it.

Yet this may not be as imposing a dilemma as it appears to be at first glance. If the course of the evolution of our species had followed a straight directional line from single cell through to us, with the achievement of consciousness as its ultimate end, then we should expect to see not only the "freedom of will" but also the "perfection of will" as its consequent results, making the question of the presence of sin in the cosmos a greater theological conundrum. (Incidentally this is why both orthogenesis and Intelligent Design fall short as explanations.) But, as was argued in God's Purpose or Nature's Dice, the physical processes of nature, including our own evolution as a species, follow no inherent "end-driven" (i.e. teleological) pathways. Consciousness, as far as the physical realm is concerned, is merely a successful adaptation of our species, and the faculty of volition, or "will," a mere byproduct of the same.

As a species we are an accumulation of our biological past, with its baggage of both useful and vestigial systems, complete with structures, faculties, and instincts that may give all the appearance of having been evolved for our particular moment in cosmic history, but have more than likely been conscripted and co-opted into service from earlier stages of our evolutionary past. This can be seen in stark detail in the evolutionary layers of the human brain: with its "reptilian layer" (i.e. brain stem and cerebellum), which controls our vital functions; the limbic or early mammalian layer (i.e. hippocampus, amygdala, hypothalamus), which constitutes not only the seat of our judgment values, but also of our unconscious behaviors; and finally, the most flexible layer, the neocortex, which we share with higher primates, constituting the seat of learning and (in humans) of higher abstract thought.

It stands to reason then that while we may call our faculty of will or volition "free," the choices set before us are certainly far from it. Luther's keen insight into the servum arbitrium comes to mind here, not the mistranslated "bondage of the will" but rather the "bondage of choice." Human choice is contextually conditioned, subject to our human finiteness, and always obliged to pay attention to our more basic "lower" instincts. The undeniable fact is that we spend most of our time suppressing and re-directing instincts we once depended on for survival and/or the passing on of our genes.The instinct of "fight or flight," once a useful defense mechanism (and still of limited value in that regard) becomes the anxiety that so afflicts our higher selves; the primal urge to reproduce easily becomes lust; the instinct to horde easily becomes greed. Indeed, in the final analysis, Aquinas' suggestion that concupiscence involves not the corruption of human nature, but rather the struggle to overcome the lower passions and desires which are natural to it, turns out to be not far from the truth.

God's Purpose or Nature's Dice? The proper role of teleology in an evolutionary account of the cosmos


An early pioneer of theistic-evolutionary thought, the Jesuit scholar, Pierre Teilhard de Chardin (1881-1955), suggested that the course of evolution followed an inevitable path, a directional course, toward a particular goal, which he termed the "Omega Point." In The Phenomenon of Man, Teilhard outlined certain watershed moments or stages along this course. The stage which saw the unfolding and development of the material universe of primordial particles resulting in the formation of the elements and chemical compounds that would serve as preconditions for biological life he termed "geosphere." That which saw the emergence and proliferation of biological lifeforms he termed "biosphere." The arrival of humanity, endowed with consciousness and a rational mind, he termed "noosphere" (from nous meaning "mind" in Greek). His final vision was that of the Omega Point, to which all creation was being drawn from the beginning. 


Some have found Teilhard's model  helpful in providing a logical outline for a theistic-evolutionary account of the cosmos. However, care should be taken in how far one goes in employing Teilhard's model, lest its use draws the charge of orthogenesis or autogenesis (i.e. progressive evolution). Classical orthogenesis is the hypothesis that evolution follows a straight or unilateral course towards an end or goal because of some internal or external driving force. Natural selection as the basic mechanism for evolution is either discounted or deemed unimportant. Typically speaking, orthogenetic models attempt to infer teleology, or final causation, in nature, meaning that design and purpose are detectable in nature. This is the fallacy of the so-called "Intelligent Design" movement.


While it certainly could be argued that an inferred teleology is necessary for a theological explanation of an evolving cosmos, teleology has no place in the scientific interpretation of the physical universe. Any theistic-evolutionary account that claims to detect teleology in nature or to replace and/or modify scientific explanations with theological ones is entirely out of bounds. The fact is, the physical processes of the universe possess no internal, directional "end-driven" goals, and there is no reason, whether theological or scientific, for the theistic-evolutionist to challenge or question this.  


However, this does not mean that intrinsically there are not directional "end-seeking" goals in the physical universe.  Specifically, one can speak of teleomatic processes (i.e. those that follow natural laws), teleonomic structures (e.g. organs or traits that serve an overall purpose), and adaptive systems (those that exist because they have survived). But these are functional descriptions, not, strictly speaking, teleological. A scientist may speak of a particular adaptation occurring in an organism for the "purpose of survival," but this is metaphorical language. What the scientist really means to say is that those organisms that adapt to their environment survive. As John S. Wilkins aptly explains:
It may help to think of a social analogy. We can explain the behaviour of a stock broker teleologically, for a stock broker seeks a goal (the best profit). We cannot explain the behaviour of a stock market, for stock markets have no goals, just outcomes. When Dawkins talks about genes maximising their representation in the gene pool, this is a metaphor not an explanation. Genes just replicate. It happens that those that out-replicate others end up out-surviving them. There is no 'goal' to genetic behaviour.
While teleology may not be valid on the level of scientific inquiry, there is certainly every reason to infer teleology in the actions of moral agents, in the social sciences, in political theory, in philosophical discourse, and ultimately in theology. Any attempt at a comprehensive understanding of reality is compelled to venture beyond the narrow restrictions of scientific inquiry and its question of "why things appear to be the way they are." Merely explaining the outcome of nature's "throw of the dice" does not satisfy the human yearning to understand the reason, purpose, goal behind the cosmos. "To what end (teleosdoes the cosmos exists at all?" "What is the purpose behind our own existence?" Indeed, the theologian's great task, particularly in light science's explanation of the "way things appear to be," is to ask, "What is God's purpose in all of this?" 


In "Theosis Interrupted," Creation was presented as an act of kenosis (divine "self-emptying"), which included the freedom to "become" as well as the freedom to "be." Hence, not only for scientific reasons, but also for good theological ones, the theistic-evolutionist is compelled to concede that material processes are undetermined, contingent and free (i.e. random), rather than determined and pre-ordained. This does not, however, negate the idea that the Creator God has created the cosmos for God's own purposes, nor the theological conclusion that, from the beginning, the Creator has been lovingly and graciously drawing the cosmos to share in the divine life -- the transformative process termed theosis.
