Enslaved by Freedom

In the early 1980s, a Christian friend waxed eloquent about the writings and thought of Francis Schaeffer to me. I was a young Christian then and respected this friend’s endorsement, but didn’t think I was up to tackling his five volume collected works which had just been published in 1982. So I bought the smallest book I could find by Schaeffer in the bookstore instead, Escape From Reason. It was so full of thoughtful theology, apologetics and philosophy that I have been reading, re-reading and referencing it since then.

In Escape from Reason, Schaeffer developed a helpful way of conceiving how the modern understanding of humanity came about. But unlike other modern thinkers, he went back to the thought of Thomas Aquinas, over three hundred years before Descartes. See “Not a Ghost in the Machine” for more on Descartes. Schaeffer thought the real birth of modern humanistic thought began with Aquinas’ distinction between nature and grace. According to Schaeffer, Aquinas thought grace was a higher level of existence that included God the Creator, heaven and heavenly things, the unseen and its influence on the earth and the human soul. The lower level of nature contained every thing created—all earthly things, all that is visible, and what nature and humans do on the earth, including the human body.

Similar to the Cartesian mind-body distinction, Aquinas did not see a complete separation between nature and grace—between the human body and soul. However, he had an incomplete view of the biblical Fall, according to Schaeffer. Aquinas thought human will was fallen, but human intellect was not. “From this incomplete view of the biblical Fall flowed all the subsequent difficulties.” In Aquinas, one realm of human existence could potentially be independent of God. Human intellect wasn’t entirely non posse non peccare— not able not to sin—to use Augustine’s description of human nature after the Fall. According to Schaeffer, this meant there was a potential for us to act as if human reason could be autonomous from God.

From the basis of this autonomous principle, philosophy also became free, and was separated from revelation. Therefore, philosophy began to take wings, as it were, and fly off wherever it wished, without relationship to Scriptures. This does not mean this tendency was never previously apparent, but it appears in a more total way from this time on.

When nature was made autonomous by Aristotelian thought in Aquinas, it began to annex grace. Schaeffer stressed that when nature is conceived as autonomous from God, it becomes destructive and it will ‘eat up’ grace. “Nature gradually became more totally autonomous. . . . By the time the Renaissance reached its climax, nature had eaten up grace.” But the Reformation was a counter balance to this autonomy of intellect.

In the Scriptures, God spoke truly about the upper level and the lower level. He spoke truly about Himself and heavenly things, and He spoke truly about nature—the created order of the cosmos and humanity. This is known as the two-books theory of God’s revelation—special revelation in Scripture and general revelation in nature. This was incidentally the starting point for many of the first modern scientists. Francis Bacon (1561-1626), an English philosopher and scientist, is generally seen as the father of empiricism. He said:

God has, in fact, written two books, not just one. Of course, we are all familiar with the first book he wrote, namely Scripture. But he has written a second book called creation.

Scripture also says we are made in the image of God, but fallen because “at a space-time point of history,” humanity sinned. Although the people of the Reformation knew they were morally guilty before God, they were not nothing. “These people knew they were the very opposite of nothing because they were made in the image of God.” And when the Word of God was listened to, the Reformation had tremendous results—in culture and in people becoming Christians.

The Bible tells us God is “both a personal God and an infinite God.” This personal-infinite God is the Creator of all things. Therefore, everything else is finite; everything else is created. This Creator-creature distinction places a chasm between God and all created things—humanity, animals, plants, and the machine. Yet when you come to the side of humanity’s personhood (Descartes’ mind-body composite), we were made in the image of God—created to have a personal relationship with Him. So humanity’s relationship is upward with God and not merely downward with the rest of the created order. Schaeffer pictured this relationship as follows:

On the side of God’s infinity, humanity is as separated from God as the Cartesian sense of machine and the other aspects of the created order. This is the Creator-creation distinction. However biblically, there is a different story on the side of human personality. Being made in the image of God, we were created to have a personal relationship with Him. Here our relationship is upward and not just downward; and there is a difference between humans and the rest of the created order.

If you are dealing with twentieth-century people, this becomes a very crucial difference. Modern man sees his relationship downward to the animal and to the machine. The Bible rejects this view of who man is. On the side of personality you are related to God. You are not infinite but finite; nevertheless, you are truly personal; you are created in the image of the personal God who exists.

Schaeffer said there is nothing truly autonomous from God; not the human mind or reason. There can be nothing apart from the lordship of Christ and the authority of the Scriptures. God made the whole person and He is interested in the whole person. While the modern humanist may have been conceived during the Renaissance, the Reformation provided the corrective to his dilemma. Although dualism in Renaissance thought has contributed significantly to the modern world’s sorrows, there is still hope in Christ. In another of his works, A Christian View of the Bible as Truth, Francis Schaeffer said:

The ancients were afraid that if they went to the end of the earth, they would fall off and be consumed by dragons. But once we understand that Christianity is true to what is there, including true to the ultimate environment—the infinite, personal God who is really there—then our minds are freed. We can pursue any question and can be sure that we will not fall off the end of the earth. Such an attitude will give our Christianity a strength that it often does not seem to have at the present time.

What happened is that rationalism evolved and became entrenched in science. The uniformity of natural causes in creation or nature was gradually closed to any intervention from outside, from God. Nature became a closed system devoid of any intervention from God. The distinction of nature and grace no longer made sense. “There was no idea of grace—the word did not fit any longer.” There was no room for revelation, so the problem was redefined in terms of freedom and nature. “Nature has totally devoured grace, and what is left in its place ‘upstairs’ is the word ‘freedom’.”

At this time we find that nature is now so totally autonomous that determinism begins to emerge. Previously determinism had almost always been confined to the area of physics; to the machine portion of the universe.

This autonomous freedom is one where the individual is at the center of the universe. It is a freedom without restraint; without limitations. Descartes’ conception of the mind as a thinking thing, the person as a fundamentally rational, mind-bound individual, fits well within this freedom. And here we can see the fulfillment of the promise of the serpent in the story of the Fall. Eating of the forbidden fruit opened human eyes and made us like God, with the freedom of knowing good and evil independent of Him. As Blaise Pascal observed: “Original sin is foolish to men” who seek to be autonomous beings.

If interested, you can watch Francis Schaeffer unfold more of his thinking in several YouTube videos. Here is a link to one on “The Flow of Materialism.”

Not a Ghost in the Machine

There is a story told about René Descartes, that he traveled with a life-sized mechanical doll he named Francine, after his illegitimate daughter. Francine died tragically when she was five. The doll was supposed to be so lifelike, that it was virtually indistinguishable from a real person. One source said he constructed it “to show that animals are only machines and have no souls.” His biographer, Stephen Gaukroger, said Descartes kept the doll in trunk beside him while he slept. Supposedly, on a voyage over the Holland Sea, the captain of the ship quietly stole into Descartes’ cabin one night and opened the trunk. Horrified to see the mechanical monstrosity, he dragged the doll from the trunk and threw her overboard.

In Descartes: An Intellectual Biography, Gaukroger said there is no truth to the tale; that it was likely a piece of propaganda in the eighteenth-century struggle against the materialism that grew out of Descartes’ philosophy. In his essay on Descartes for Galileo Goes to Jail, Peter Harrison said Descartes could be the most maligned and misunderstood philosopher who ever lived. “Indeed, there seems to be something about Descartes’ person and his philosophy that invites slander and simplistic mischaracterization.” Both Gaukroger and Harrison pointed to another misconception, that Descartes initiated the radical separation of mind and body, which then had disastrous consequences on Western philosophy.

Descartes did make a mind-body distinction. The Internet Encyclopedia of Philosophy said one of the most lasting legacies of his philosophy is what is now called mind-body dualism.  He argued that the nature or substance of the mind (a thinking non-extended thing) was completely different from that of the body (an extended, non-thinking thing). Harrison noted where the Oxford philosopher Gilbert Ryle derisively referred to this Cartesian doctrine of mind and body as “the myth of the ghost in the machine.” Such dualism, according to Ryle, was “fundamentally antiscientific.”

But there is a technical point missing in this portrayal of Descartes’ thinking. He considered the body and mind to be distinct substances. “A substance is something that does not require any other creature to exist—it can exist with only the help of God’s concurrence.” As a consequence, each could exist without the other. “However, this does not mean that these substances do exist separately.” Harrison said Descartes carefully rejected the kind of separation implied by Ryle and others.

In fact, Descartes took pains to deny such a separation, asserting that mind and body are “intermingled” so as to form a “unitary whole.” Mind and body, he insists, form a “substantial union.” He also unambiguously states (pace Dennett) that the mind is not in the body “as a pilot in his ship.” . . . In fact, the doctrine of a radical separation of mind and body is one that should more properly be laid at the feet of Aristotle or Plotonius, rather than Descartes.

Some commentators have suggested the interaction of mind and body was so central a concern for Descartes that it is misleading, to a certain extent, to refer to him as a dualist. He sought to understand the world in terms of three basic kinds of entity—matter (extended material things), minds (thinking things) and persons (mind-body composites). Correlations between mental events and bodily movements are merely natural properties of this body-mind complex. “The relations of mind and body, on this account, are explained in terms of psychophysical laws that constitute our very nature as embodied beings.” Harrison then gave this summation.

In sum, Descartes’ views about mind, body, and their relation are subtle, sophisticated, and complex. They bear little resemblance to the simplistic caricatures that often pose as authoritative accounts of his work. Descartes gave a central place to the emotions in his psychology, and he took very seriously the embodied nature of human beings. Because of Descartes’ insistence that the mind-body amalgam was a real entity, some commentators have gone as far as to suggest that he no longer be numbered in the ranks of the dualists.

Writing for BioLogos, philosophy professor Edward Fesler said to the extent that this separation and conception is seen as “an abstraction from concrete material reality, and not the whole of material reality,” there is nothing wrong with it. However, there must be a clear acknowledgement of its limitations. “It captures only those aspects [of reality] that are susceptible both of mathematical modeling and of detection vie experimental techniques by which the models may be tested. But anything else falls short.” Unlike Harrison, Fesler does see Descartes as responsible for many of the philosophical problems that came after his conception of mind and matter.

This bizarre re-conception of human nature—man as a “ghost in a machine,” as Gilbert Ryle famously parodied it—opened up a host of philosophical problems which persist to this day. The materialist “solution” to the problems has been to reject one of Descartes’ reified abstractions (the res cogitans) while keeping the other, the material world conceived as if the equations of physics exhausted its nature. Unsurprisingly, this has led to theories of the relationship of mind to body which seem implicitly to deny, rather than to explain, the existence of mind, consciousness, meaning, and free choice.

The materialist resolution of the mind-body problem raised by Cartesian philosophy, subsuming the mind as an extension of bodily neurological functions, raises a problem for a biblical understanding of human nature. While there is a clear sense of a kind of dualism in Scripture, Christians cannot assume such a materialist position. Biblically speaking, humans are material and immaterial, body and soul. Fesler’s suggestion is to reject Descartes’s abstractions and rediscover the human being “as an irreducible psychophysical whole,” with our mental and physical as two aspects of one thing. There is both unity and distinction—what theologian Anthony Hoekema referred to as a psychosomatic unity of body (soma) and soul (psyche). See “We Are But Thinking Reeds” for a more in depth discussion of this idea.

But there is a third kind of Cartesian entity to consider—the mind-body composite of personhood. It is an essential aspect of human existence as it makes possible the relationship between individual humans, between embodied thinking things. An it makes possible a relationship with God. So it cannot be easily dismissed as merely a ghost in the machine.

Abeba Birhane offered a revision of Descartes for Aeon that adds a community aspect to Carteasian thought. Drawing upon Ubuntu philosophy, she said selfhood is acquired over time. She illustrated this concept by quoting the Kenyan-born philosopher John Mbiti: “I am because we are, and since we are, therefore I am.” Note the rephrasing of Descartes’ famous quote: “I think, therefore I am.” Birhane said we know from everyday experience that personhood is partly formed in community. Who we are depends upon many others—family, friends, culture, etc. She quoted a Zulu phrase, saying it was a better and richer account of personhood than Descartes cogito argument: “A person is a person through other persons.”

Biblically speaking, human personhood is also the result of being created in the image of God. Humanity, “being made in the image of God, was made to have a personal relationship with him.” In Escape from Reason, Francis Schaeffer said that when speaking of God to modern humans, it is important to emphasize that the Bible speaks of God as both a personal God and an infinite God. This is the kind of God who is there; who actually exists. And He is no ghost in the machine.
