Introduction
You live in a culture that feels hopelessly fragmented, where science and values seem to speak entirely different languages. You likely notice that modern art, philosophy, and media offer no unified picture of truth, leaving you adrift in a sea of subjective opinions.
Francis A. Schaeffer argues that this cultural despair stems from a deliberate historical split between nature and grace. Western thought abandoned the unity of knowledge, creating a destructive dichotomy between rational determinism and non-rational faith.
The book traces this intellectual collapse from the Renaissance through the Enlightenment to modern existentialism. You will discover how a shift in philosophy fractured art, theology, and science.
The book answers several key questions:
- How did the separation of nature and grace start?
- Why did modern science lead to human determinism?
- How do people try to escape the upper-story leap?
- Can you restore a unified biblical worldview?
1. Historical Roots of Secularism and Art
Nature and Grace
Thomas Aquinas introduced a distinction between nature and grace that viewed the will of man as fallen while the intellect remained unfallen, setting up an autonomous sphere for human philosophy. Thomas Aquinas lived from 1225 to 1274.
Thomas Aquinas separated nature from grace by declaring the human intellect unfallen, which unintentionally birthed autonomous humanism and naturalistic art.
Aquinas created a two-level model where grace represented the higher realm of God, heaven, and the soul, while nature represented the lower realm of earthly things and the body. Because the intellect was deemed unaffected by the Fall, philosophy and natural theology became independent of Scripture, eventually opening the door for autonomous humanism to develop.
Artistic Shifts
As nature was rendered autonomous in Renaissance art, the lower earthly elements gradually overtook and replaced the higher spiritual subjects. Nature eats up grace when the lower story consumes the upper story.
Artistic representation shifted from Byzantine symbols to naturalistic portrayals of the physical world. In 1410, Van Eyck produced a tiny miniature containing the first real landscape. In 1435, Van Eyck painted the Madonna of the Chancellor Rolin.
Eventually, painters began depicting sacred figures like Mary using real local women, such as mistresses, effectively eliminating the distinction of the upper spiritual story. Filippo Lippi painted a Madonna using his own mistress as the model, and Fouquet painted the king's mistress, Agnes Sorel, as Mary with one breast exposed.
2. The Reformation and Early Science
The Reformation Solution
The Reformation rejected autonomous humanism by asserting a total Fall of man. This meant you could not exempt the human intellect from the corruption of sin.
John Calvin published his Institutes in 1536, having been born in 1509. He and other reformers maintained that man and his reason are fully fallen. Nothing remains autonomous except God.
The Reformation provided a true unity of knowledge because both spiritual and physical realms stood under biblical revelation.
You found that Scripture Alone and Faith Alone secured final authority without dividing nature from grace. The Bible presented a personal-infinite God who created man in His image.
Unlike Eastern religions with impersonal forces, your primary relationship pointed upward toward a rational Creator. This gave you genuine value and significance as a finite creature.
The Rise of Early Science
Modern science was successfully launched because Christianity provided a unique climate of thought. You inherited an objective, real universe open to investigation.
Francis Bacon lived from 1561 to 1626, helping shape this scientific movement. Early scientists did not view science as autonomous.
- They operated on the premise that a rational God created a uniform universe outside of Himself.
- They embraced the uniformity of natural causes without trapping God and man inside a closed system.
You could study the physical world confidently. The universe was not a chaotic illusion or a divine substance, but a created order.
3. From Nature and Freedom to Determinism
By the time of Kant and Rousseau, grace completely disappeared from secularized philosophy, replacing the nature-grace tension with a conflict between deterministic nature and autonomous freedom. As naturalistic science gained dominance, human freedom was treated as entirely autonomous and unrestrained, leading individuals to reject civilization and science as threats to human liberty. This set up an irreconcilable opposition between the mechanical universe and human self-expression.
As secular philosophy replaced grace with autonomous freedom, modern science trapped humanity inside a deterministic closed system, culminating in nihilistic morality.
Jean-Jacques Rousseau lived from 1712 to 1778, while Immanuel Kant lived from 1724 to 1804. They wrestled with nature and freedom, trying to salvage human significance. Kant separated the phenomenal world of mechanical necessity from the noumenal world of human freedom. Rousseau championed autonomous freedom against the crushing weight of social structures and civilization.
Determinism in Science and Morality
The shift from the uniformity of natural causes to a closed system merged all disciplines into the machine, eliminating human freedom, love, and objective significance. Modern science expanded physical determinism into psychology and the social sciences. In doing so, it achieved unity by entirely erasing the upper story of freedom and spirit, leaving man trapped within a purely deterministic framework.
The Marquis de Sade lived from 1740 to 1814. He acted as a chemical determinist, arguing that if man is merely a machine, traditional morals do not exist and whatever nature dictates through strength is right.
De Sade laid the philosophical groundwork for modern black and pornographic writers by arguing that societal morals are merely tools for manipulation. Under total determinism, physical dominance and natural impulse replace ethical standards, providing a rationale for cruelty and violence. You see the logical outcome of a closed deterministic system where moral choice dissolves into chemical necessity.
4. The Line of Despair and Modern Dichotomy
Georg Wilhelm Friedrich Hegel lived from 1770 to 1831 and changed philosophical methodology. Faced with failing rationalism, thinkers replaced classical antithesis with thesis-antithesis-synthesis.
Søren Kierkegaard lived from 1813 to 1855 and accepted this break. He separated faith from rationality and abandoned the ancient aspiration for a unified field of knowledge.
Kierkegaard and Hegel drove modern thought below the Line of Despair, creating a total dichotomy where lower-story rationality equals pessimism and upper-story faith requires a non-rational leap.
The Line of Despair
Below the line of the great dichotomy lies rationality, mathematics, and mechanics. This realm renders man dead and meaningless. Above the line, you rely on a non-rational and non-reasonable leap to attain optimism and hope.
A ten-thousand-foot-thick concrete wall separates the upper and lower stories.
Secular Existentialism and New Theology
Secular existentialism attempts to find meaning through non-rational upper-story acts, final experiences, or dread, but each stream collapses into subjective hopelessness. Jean-Paul Sartre attempts self-authentication through arbitrary acts of the will because all directions of the will are equal. Karl Jaspers relies on an uncommunicable final experience that cannot be prepared for or sustained. Martin Heidegger anchors existence in Angst, a vague dread without a specific object.
A student from the Free University in Amsterdam held onto a final experience felt at Green Pastures. Two years later, that student was close to suicide because such experiences cannot be sustained or communicated.
The New Theology and neo-orthodox systems abandon historical and rational truth in the lower story. They rely instead on undefined religious connotation words in the upper story to create an illusion of communication. By accepting biblical criticism and separating religious truth from history and the cosmos, the new theologians use powerful traditional words as undefined symbols.
Paul van Buren suggests in The Secular Meaning of the Gospel that although the word God is dead, you lose nothing. You supposedly have all you need in the non-defined symbol of Jesus Christ.
5. Upper-Story Leaps in Art, Drugs, and Madness
Trapped in the machine, modern culture seeks upper-story escape through psychedelic drugs, abstract art, pornography, the Theater of the Absurd, and madness.
Drugs and Art
Faced with the meaninglessness of the rational world, you can watch modern culture turn to drugs to induce direct mystical states called first-order experiences. Aldous Huxley advocated using drugs like LSD and mescaline to bypass rational lower-story meaninglessness and achieve direct mystical experiences. Timothy Leary popularized this view by calling culture a fake-prop-set society, mirroring ancient Eastern mystical practices.
Aldous Huxley advocated the use of drugs by healthy people for first-order experiences right before his death, as written in the last chapter of The Humanist Frame.
Contemporary art and artists often express the tension of man trapped in the machine, resorting to ugliness, abstraction, or irrational leaps when rational universal creation fails. Picasso attempted to create a universal through extreme abstraction, which destroyed communication with the viewer. When he fell in love, communication was restored through an irrational leap based on personal affection rather than the rational subject matter of the painting.
When Picasso fell in love with Eva, he wrote J'aime Eva across his canvas to restore human communication irrationally. Later, when he fell in love with Olga and Jacqueline, he painted them in human forms to express an irrational leap.
Pornography and Madness
Modern serious pornography and the Theater of the Absurd operate as philosophical statements and upper-story leaps intended to smash rational tyranny and release a new golden age. Writers like Henry Miller and Terry Southern use pornography not merely for dirt, but as serious statements suggesting that psychological orientation destroys the concept of crime, hoping a new ethic will emerge from the release. Similarly, the Theater of the Absurd uses abnormal syntax and non-communication to reach an upper-story mysticism beyond reason.
Terry Southern's novel Candy features a character named Candy Christian who smashes the Christian position, reflecting a cultural shift where pornography is positioned as the ultimate release and leap to freedom.
The logical conclusion of autonomous freedom and the rejection of rational Enlightenment promises is the embrace of madness. Michel Foucault's Madness and Civilization rejects the authority of reason due to the failure of nineteenth-century systems. Following Rousseau, Foucault elevates mad artists and thinkers as true critics of the world, suggesting that the ultimate state of autonomous freedom is being insane.
San Francisco hippies adopted the tune of We Shall Overcome for the words We Are All Insane, illustrating how advanced contemporary thought aligns madness with freedom.
6. Restoring the Biblical Worldview
To effectively reach modern people, Christians must reject the sacred-secular dichotomy and present Christianity as a unified answer to the whole of life.
Modern people have accepted despair and the dichotomy because rationalistic presuppositions forced them there, not because they wanted to. Christianity offers a unified worldview that allows man to renounce rationalism and recover true rationality based on verifiable discussion, rather than hiding behind unthinking evangelical slogans.
The biblical system can be placed in the marketplace of ideas to stand on its own, offering a cohesive structural framework that links all human problems together. The author spent six months reading the Bible and became a Christian because its system uniquely resolved his intellectual problems.
Evangelical Dangers and True Truth
Evangelical Christians must avoid adopting the modern dichotomy by separating an experiential encounter with Jesus from the discussable, verifiable propositional content of the Scriptures.
If evangelicals replace biblical propositional truth with an unverified upper-story encounter under the banner of Jesus, the name of Jesus becomes a contentless, highly motivated slogan. This contentless banner can be co-opted to justify behavior directly contrary to what the historical Jesus taught. T. H. Huxley predicted in 1890 that faith would remove all content and become inaccessible to attack. Marghanita Laski noted in the December 16, 1966 issue of the Weekend Telegraph that new mysticisms place religious claims beyond proof or disproof, warning that modern religious language is being removed from the realm of discussable fact.
Communicating in a Changing World
Christians must maintain unchangeable biblical principles while actively adapting their language and thought-forms to communicate effectively with each changing generation. Failing to understand the shifting thought-forms of contemporary culture renders the gospel incomprehensible, much like sending missionaries to China who stubbornly learn only one dialect out of three.
You must meet changing cultural conditions through deliberate actions:
- Examine current thought-forms and mass media influences shaping younger generations
- Engage in heart-searching regarding how to speak eternal principles into changing historical situations
- Refuse to alter unchangeable scriptural facts while adapting communicative language
