In the twilight of the Middle Ages and the dawning light of the Renaissance, few intellects shone as brightly or as uniquely as Nicholas of Cusa. Born Nikolaus Krebs in 1401 in the town of Kues (Cusa) on the Moselle River, he emerged from humble beginnings to become a cardinal, a papal legate, and one of the most profound philosophers in Western history. His life spanned a tumultuous era marked by the Great Schism of the Church, the threat of the Ottoman Empire, and the rediscovery of classical antiquity, yet his mind was fixed on a timeless horizon. Educated in the rigorous legal traditions of Padua and the theological depths of Cologne, Cusa synthesized mysticism with mathematics, and canon law with cosmology, creating a worldview that was centuries ahead of his time. He was a man who walked the delicate line between the dogmatic certainties of the medieval scholastics and the inquisitive, humanistic spirit of the coming age, ultimately bridging the gap through his revolutionary concept of "learned ignorance."
Cusa’s intellectual journey reached a pivotal moment in 1437 while returning by sea from Constantinople. He experienced a profound revelation—a "gift from the Father of Lights"—which led him to conclude that the human mind, being finite, can never fully grasp the infinite truth of God through rational logic alone. This epiphany birthed his magnum opus, *De Docta Ignorantia* (On Learned Ignorance), where he argued that true wisdom lies in recognizing the limits of one's own knowledge. Unlike the Aristotelians who sought to categorize the world into rigid definitions, Cusa envisioned a universe of infinite possibilities where contradictions are resolved in the divine unity. He proposed that God is the "coincidence of opposites," a state where maximum and minimum, motion and rest, and diversity and unity converge. This dialectical approach allowed him to speculate on a universe without a fixed center, anticipating the cosmological shifts of Copernicus and the infinite worlds of Giordano Bruno.
The legacy of Nicholas of Cusa is not merely that of a theologian but of a visionary who dared to look into the abyss of the infinite and found there a reflection of the divine intellect. His work laid the groundwork for modern epistemology and the scientific revolution, challenging the geocentric model and advocating for religious tolerance in *De Pace Fidei* (On the Peace of Faith). He saw the intellect as a living mirror of the divine, capable of approaching the truth asymptotically—getting closer and closer but never quite touching the absolute, much like a polygon multiplying its sides within a circle. In a world often paralyzed by binary conflicts and rigid dogmas, Cusa’s philosophy remains a beacon of intellectual humility and mystical insight. His life was a testament to the power of the mind to transcend its own boundaries, urging humanity to embrace the mystery of existence not with fear, but with a learned and reverent ignorance.
50 Popular Quotes from Nicholas of Cusa
The Philosophy of Learned Ignorance
"All we know of the truth is that the absolute truth, such as it is, is beyond our reach."
This quote encapsulates the central thesis of Cusanus's epistemology, serving as the foundation for his concept of *docta ignorantia*. He posits that the human intellect is finite and therefore structurally incapable of fully comprehending the infinite nature of absolute truth or God. Rather than a defeatist admission of skepticism, this is a call to intellectual humility, recognizing that our knowledge is always partial and approximate. By accepting that the absolute is beyond our grasp, we open ourselves to a perpetual journey of learning that is driven by wonder rather than arrogance.
"The intellect, which is not truth, never comprehends truth so precisely that it cannot be comprehended more precisely."
Here, Nicholas employs a mathematical analogy to describe the nature of human understanding, suggesting that knowledge is an infinite progression. Just as a polygon can increase its sides infinitely to resemble a circle but will never actually become a circle, the human mind can approach truth ever more closely without ever fully encompassing it. This statement challenges the static dogmatism of his era, proposing instead a dynamic view of knowledge where there is always room for refinement and deeper insight. It validates the scientific method of continuous inquiry and revision long before the scientific revolution took hold.
"To know is to measure."
In this concise maxim, Cusanus links the act of cognition directly to the act of comparison and measurement, highlighting the relational nature of human knowledge. He suggests that we understand new concepts by comparing them to what we already know, using a mental scale to gauge differences and similarities. This foreshadows the quantitative approach of modern science, where understanding the physical world is predicated on the ability to measure and quantify phenomena. However, it also implies a limitation, as the divine infinite cannot be measured, and thus cannot be fully "known" in this conventional sense.
"The precise truth shines incomprehensibly within the darkness of our ignorance."
This poetic assertion reflects the mystical dimension of Cusa's thought, drawing on the tradition of negative theology or apophaticism. He argues that while the rational mind cannot grasp the absolute, the intellect can intuit the presence of truth through the very recognition of its limits. The "darkness" here is not an absence of light, but a dazzling brilliance that overwhelms the finite faculty of sight, requiring a different mode of perception. It suggests that the highest form of knowledge is a "dazzling darkness" where the soul encounters the divine mystery directly.
"A man, then, is a microcosm, or a little world; for he has inside himself, in potentiality, all things."
Reviving the ancient concept of the microcosm, Cusa elevates the status of the human being as a reflection of the entire cosmos. He argues that the human mind contains the seeds of all reality, possessing the cognitive capacity to reflect and understand the universe. This idea bridges the gap between the subject and object, suggesting that by looking inward, one can discover the fundamental principles that govern the external world. It places humanity at a crucial intersection of creation, serving as the bond that unites the spiritual and material realms.
"Wisdom is not found in the art of rhetoric, but in the recognition of one's own ignorance."
Cusanus critiques the scholastic and humanist tendency to value eloquent speech and persuasive argumentation over genuine insight. True wisdom, for him, is an internal state of awareness regarding the limits of human reason, rather than the external ability to manipulate language. This quote serves as a reminder that intellectual vanity often obscures the truth, while humility clears the path for genuine understanding. It is a timeless admonition against the pretense of knowledge, urging a return to the Socratic principle that the wise man knows that he knows nothing.
"The more we know that we are ignorant, the more we attain to learned ignorance."
This statement defines the paradox of his philosophy: that the accumulation of knowledge should lead to a greater awareness of the unknown. As one's sphere of knowledge expands, the perimeter of contact with the unknown also increases, deepening the sense of mystery. "Learned ignorance" is therefore an active, high-level intellectual state, distinct from mere stupidity or lack of education. It represents the pinnacle of human wisdom, where the mind stands in awe before the infinite complexity of reality.
"Reason falls short of the truth, just as a polygon, no matter how many sides it has, never coincides with the circle."
Cusa frequently uses this geometric metaphor to illustrate the ontological gap between the finite mind (the polygon) and the infinite truth (the circle). Even if the polygon multiplies its sides to infinity, it remains a shape composed of straight lines, whereas the circle is a continuous curve. This analogy demonstrates that there is a qualitative difference between human reasoning and divine reality that cannot be bridged by mere accumulation of facts. It emphasizes that the transition from the finite to the infinite requires a leap of faith or mystical intuition, not just logical deduction.
"Every inquiry creates its own measure."
This insight anticipates modern theories of relativity and quantum mechanics, suggesting that the observer influences the observation. Cusanus implies that the tools and concepts we use to investigate the world shape the answers we receive. We cannot step outside our own cognitive frameworks to see the world "as it is" objectively; we always measure it against our own mental constructs. This highlights the subjective element inherent in all human knowledge and warns against assuming our perspective is absolute.
"Desire is the beginning of all knowledge."
Nicholas acknowledges the emotional and volitional drive that underpins the intellectual quest. He argues that the intellect is not a cold, mechanical processor but is propelled by a natural longing for truth and beauty. This "intellectual desire" acts as a gravitational force, drawing the mind toward its source, which is God. It suggests that the pursuit of knowledge is a form of love, a spiritual yearning to reconnect with the ultimate reality from which we originated.
The Coincidence of Opposites
"God is the coincidence of opposites."
This is Cusanus's most famous metaphysical definition, describing God as the locus where all contradictions are resolved. In the finite world, things are defined by what they are not—hot is not cold, light is not dark—but in the infinite nature of God, these distinctions vanish. This concept challenges the Aristotelian law of non-contradiction, proposing a higher logic applicable to the divine. It suggests that to understand God, one must transcend binary thinking and embrace a holistic vision where conflicting truths merge into a singular unity.
"In God, the absolute maximum is the absolute minimum."
By equating the maximum and the minimum, Cusanus illustrates the breakdown of relative measurements within the infinite. If a circle is expanded infinitely, its curvature becomes a straight line; thus, the infinite circle and the infinite line are one. Similarly, God is the "maximum" because nothing can be greater, but also the "minimum" because he is present in the smallest particle of existence. This paradox destroys the hierarchy of size and scale, revealing that the divine essence is equally present in the vastness of the cosmos and the tiniest atom.
"The wall of Paradise is built of contraries."
Cusanus uses this vivid metaphor to describe the barrier that separates finite human logic from the vision of God. The "wall" consists of contradictory assertions that the rational mind cannot reconcile, such as God being both hidden and revealed, or transcendent and immanent. To enter the "Paradise" of divine knowledge, the intellect must leap over this wall, abandoning the rigid structures of logic. It signifies that spiritual enlightenment requires a transcendence of dualistic thinking, moving beyond the "either/or" to the "both/and."
"Opposites coincide in the infinite."
This principle extends the idea of the coincidence of opposites to the very nature of infinity itself. In a finite context, opposites exclude each other, but in an infinite context, they embrace. For example, the past and the future coincide in the eternal "now" of God. This quote serves as a metaphysical key, unlocking the understanding that the fragmentation we experience in the temporal world is an illusion when viewed from the perspective of eternity. It offers a vision of ultimate reconciliation and peace.
"Absolute unity is the coincidence of oneness and plurality."
Cusa addresses the classic philosophical problem of the One and the Many. He argues that true unity is not the absence of diversity, but the containment of all diversity within itself. God is not "one" in the sense of being a single numerical item, but "one" in a way that enfolds all possible multiplicities. This dialectic allows for a worldview that values diversity as an expression of the divine unity, rather than a deviation from it.
"The straight line and the curve are the same in the infinite."
Using geometry to prove theological points, Cusa asks us to imagine a circle with an infinite radius. As the circle grows, the curve becomes less bent; at infinity, the circumference is indistinguishable from a straight line. This metaphor demonstrates how qualities that appear distinct and contradictory to the finite eye are identical in the absolute. It serves as a powerful tool for visualizing how the divine nature transcends the limitations of spatial and logical categories.
"Rest and motion coincide in the Absolute."
In the physical world, an object is either moving or at rest, but for God, who is everywhere at once, motion and rest are the same. God moves at infinite speed, which is indistinguishable from being instantly present everywhere (rest). This paradox highlights the dynamic nature of the divine, which is not a static entity but an active, living presence that permeates all of reality. It challenges the Aristotelian "Unmoved Mover" concept by suggesting a God who is both the motion and the stillness.
"Darkness is not the opposite of light, but the threshold of a greater light."
Interpreting the coincidence of opposites mystically, Cusa suggests that spiritual darkness is often a sign of proximity to God. When the mind is blinded by the intensity of divine truth, it experiences darkness, but this is actually an excess of light. This reframes the experience of the "dark night of the soul" not as abandonment, but as a profound encounter with the divine essence that strips away the reliance on sensory and intellectual crutches.
"Complexity is but the unfolding of simplicity."
Cusanus introduces the concepts of *complicatio* (enfolding) and *explicatio* (unfolding). He argues that the complexity of the universe is merely the unfolding of the simple unity found in God. Just as a single point contains the potential for all lines and shapes, the simple essence of God contains the entire complex universe. This quote connects the One and the Many, showing that the diverse world is the visible manifestation of the invisible, simple God.
"In the coincidence of opposites, the intellect finds its rest."
While the rational mind struggles with contradictions, the higher intellect (intellectus) finds peace in the resolution of opposites. Cusa suggests that the soul is restless as long as it is trapped in binary conflicts. True intellectual peace and spiritual satisfaction are found only when one ascends to the vision of unity where all conflicts are harmonized. This is the ultimate goal of the philosopher and the mystic alike.
The Nature of God and the Infinite
"God is not other; He is the Not-Other."
In his later work *De Li Non Aliud*, Cusanus defines God as the "Not-Other." This is a sophisticated way of saying that God cannot be defined in opposition to anything else, because God is the ground of all being. If God were "other" than the world, He would be limited by the world. By being the "Not-Other," God is the essence of everything without being identical to any specific thing. This formulation avoids both pantheism and dualism, maintaining God's transcendence and immanence simultaneously.
"God is the enfolding of all things, and the unfolding of all things."
This famous distinction between *complicatio* (enfolding) and *explicatio* (unfolding) explains the relationship between Creator and creation. God "enfolds" all things in that everything exists potentially within Him in a state of unity. He "unfolds" all things in that the universe is the manifestation of His internal potentiality in time and space. This dynamic view portrays creation not as a one-time manufacturing event, but as a continuous expression of the divine nature.
"God is the Absolute Maximum, which cannot be greater."
Cusanus begins *De Docta Ignorantia* by defining God as the Absolute Maximum. Because nothing can be opposed to the Absolute Maximum (since it encompasses everything), it is also free from all limitation. This definition serves as the starting point for his mathematical theology, establishing God as the ultimate standard against which all finite things are measured. It asserts the sovereignty and all-encompassing nature of the divine.
"The face of God is the absolute face of all faces."
In *De Visione Dei* (The Vision of God), Cusa uses the analogy of a painting with an omnivoyant gaze (eyes that seem to follow the viewer everywhere). He argues that God’s "face" is the archetype of all human faces and all truth. When we look at God, we are looking at the source of our own identity. It implies that in seeking God, we are ultimately seeking the truest version of ourselves, and that God's gaze defines our very existence.
"God is closer to us than we are to ourselves."
Echoing Augustine, Cusa emphasizes the radical immanence of God. Because God is the "Not-Other" and the sustaining ground of our being, He is present in the very core of our consciousness. This quote dismantles the idea of a distant, sky-dwelling deity, suggesting instead that the divine presence is the most intimate reality of our lives. It calls for an inward journey to find the sacred, rather than an outward search.
"We cannot comprehend God, but we can be comprehended by Him."
This statement reverses the direction of the epistemic relationship. While our finite minds cannot wrap around the infinite God, we exist within His infinite understanding. This realization brings comfort and humility, shifting the focus from our power to grasp the truth to our willingness to be held by the Truth. It suggests that faith is an act of surrender to a greater consciousness that knows us fully.
"God is the center and circumference of all that is."
Combining his cosmological and theological insights, Cusa describes God as the ubiquitous center of reality. In an infinite sphere, the center is everywhere and the circumference is nowhere; similarly, God is centrally present in every atom and yet bounds the entire cosmos. This imagery portrays a God who is inescapable, permeating every aspect of existence while also transcending it.
"To see God is to see that He is invisible."
This paradox reinforces the apophatic tradition. A true "vision" of God is the realization that He transcends all visual and conceptual categories. If one claims to "see" God as a specific object or form, they are mistaken. True spiritual sight acknowledges the invisibility of the divine essence, perceiving God through the eyes of faith and intellectual intuition rather than sensory perception.
"God is the possibility of all possibilities."
Cusanus views God as the *Possest* (Actualized-Possibility), a term he coined to signify that in God, absolute possibility and absolute actuality are one. In the finite world, potential exists that is not yet actual, but in God, everything that can be, is. This quote highlights God as the ultimate source of all potentiality, the reservoir from which all existence flows. It suggests a dynamic, creative God who is the very power of existence itself.
"The infinite is the absolute actuality of all that can be."
Similar to the previous quote, this emphasizes that the infinite is not an empty void, but a fullness of being. The infinite God does not lack anything; He is the full realization of all potential. This counters the notion of infinity as a chaotic abyss, presenting it instead as the perfect completion of reality where nothing is wanting.
Cosmology and the Universe
"The universe has no circumference, for if it had a center and a circumference, it would have some beginning and some end in itself."
This is a groundbreaking cosmological assertion that challenged the Aristotelian and Ptolemaic models of a bounded, spherical universe. Cusanus argued that the universe is "privatively infinite"—limitless—because only God is absolutely infinite. By denying a physical boundary, he opened the door to the concept of an immense, perhaps endless universe, paving the way for the astronomical revolutions that would follow.
"The earth is a noble star."
In a time when the earth was considered the heavy, corrupt "sink" of the universe at the center, Cusanus elevated its status. By calling it a "noble star," he suggested that the earth is of the same nature as the celestial bodies, glowing with its own light (reflected or otherwise). This shattered the medieval dichotomy between the corrupt sublunary world and the perfect celestial spheres, effectively integrating the earth into the heavens.
"The earth is not the center of the universe."
Long before Copernicus, Nicholas of Cusa deduced that if the universe is limitless, it cannot have a fixed physical center. Therefore, the earth cannot be the center. This was a philosophical deduction rather than an astronomical observation, but it was a radical departure from the geocentric dogma. It displaced humanity from the physical center of creation, forcing a re-evaluation of our place in the cosmos.
"There is no fixed point in the universe."
Building on the lack of a center, Cusa argued that everything in the universe is in motion relative to everything else. Without a fixed circumference, there can be no absolute stationary point. This foreshadows the principle of relativity, suggesting that motion is always relative to the observer's position. It portrays a dynamic, fluid universe where stability is a matter of perspective, not absolute reality.
"Every observer, whether on earth, the sun, or another star, thinks himself to be at the immovable center."
Cusanus recognized the psychological and perceptual bias inherent in observation. We perceive the universe from our own vantage point, making it appear as though everything revolves around us. He posited that an observer on the sun would feel the same way. This insight into the relativity of perception is crucial for understanding his cosmology and his philosophy of knowledge—we project our own stability onto the cosmos.
"The machine of the world has its center everywhere and its circumference nowhere."
This famous hermetic maxim was popularized by Cusa to describe the structure of the universe. It implies that every point in space has equal value and is equidistant from the divine source. It democratizes the cosmos, removing the privileged status of any specific location. It also serves as a theological metaphor: God is equally accessible from every point in the universe.
"Life exists in other worlds as it does in ours."
Cusanus speculated on the existence of extraterrestrial life, reasoning that if God is the author of life and the universe is vast, it would be absurd for life to exist only on earth. He imagined inhabitants of the sun and moon, adapted to their specific environments. This demonstrates his willingness to push the boundaries of imagination and his belief in the fecundity of God's creation.
"The universe is a restricted infinity."
Cusa distinguished between the "absolute infinity" of God and the "privative infinity" (or indeterminacy) of the universe. The universe is not God, so it is not absolutely infinite, but it is not finite in the sense of having a brick wall at the end of it. It is "restricted" by its nature as a created thing but "infinite" in its lack of boundaries. This nuanced distinction allowed him to expand the cosmos without equating it with the Creator.
"Motion is the mode of existence for the universe."
Unlike the static models of antiquity, Cusa saw the universe as fundamentally dynamic. Just as the intellect is always in motion toward truth, the physical universe is in constant motion. This aligns with modern physics, which recognizes that everything from atoms to galaxies is in a state of perpetual movement. It reflects a theology where God is the dynamic life-force sustaining a moving creation.
"The world is an explication of God, but God remains the complication of the world."
This reiterates the relationship between the cosmos and the divine. The world is God "unfolded" into time and space, revealing his glory in diverse forms. However, the world does not exhaust God; He remains the "enfolding" unity that transcends the world. This maintains the balance between the sacredness of nature and the sovereignty of the Creator.
Faith, Peace, and the Intellect
"There is only one religion in the variety of rites."
In *De Pace Fidei* (On the Peace of Faith), written after the fall of Constantinople, Cusa argued for religious tolerance. He suggested that beneath the surface differences of liturgy and custom, all religions are seeking the same one truth and the same one God. This was a radical proposal for peace in a time of religious war, advocating for dialogue based on the universal desire for the divine.
"Faith is the beginning of understanding."
Cusanus followed the Augustinian tradition of *credo ut intelligam* (I believe in order to understand). He argued that one must have a foundational trust or intuition of the truth before the intellect can analyze it. Faith provides the starting point and the orientation for the intellectual journey. Without the initial leap of faith, reason has no ground upon which to stand.
"The intellect is a living mirror of the eternal Word."
He viewed the human mind not as a passive receptacle, but as a "living mirror" that actively reflects the divine Logos. A living mirror can adjust itself to capture the image more clearly. This metaphor emphasizes the active role of the human spirit in aligning itself with God, suggesting that our intellectual capacity is a direct participation in the divine nature.
"Peace is the fulfillment of all intellectual desire."
For Cusanus, the ultimate goal of philosophy and theology is peace—both internal peace of the soul and external peace among nations. This peace is achieved when the intellect rests in the unity of the coincidence of opposites. It suggests that conflict arises from partial, fragmented knowledge, while true wisdom leads inevitably to harmony and reconciliation.
"Man is a second god."
This bold humanist statement asserts the creative power of humanity. Just as God creates the real world, humans create a mental world of concepts, mathematics, and arts. We are "gods" by participation, endowed with the spark of divine creativity. It elevates human dignity and responsibility, calling us to act as co-creators and stewards of the world.
"The game of the sphere represents the movement of the soul."
In his book *De Ludo Globi* (The Game of the Sphere), Cusa uses a bowling-like game as a metaphor for the soul's journey. The bowling ball is not perfectly round, and its path is spiral. This illustrates that the soul's movement toward God is not a straight line but a complex, non-linear path influenced by its own "weight" (character) and the "throw" (divine grace). It is a playful yet profound image of the spiritual life.
"Intellectual vision requires the eye of the mind to be washed by the tears of humility."
Cusanus constantly links intellectual progress with moral purification. One cannot see the truth if the mind is clouded by pride. Humility acts as a cleansing agent, removing the distortions of ego. This quote reminds us that being a great thinker requires being a good person, grounded in the reality of one's own limitations.
"Unity is the source of all number, yet it is not a number."
Using arithmetic theology, he explains that "one" is the source of all numbers (2, 3, 4...) but stands outside the sequence as its generator. Similarly, God is the source of all beings but is not just another being among them. This helps explain God's transcendence: He is the precondition for existence, not merely a part of it.
"Let there be one faith, one prayer, and one worship of the one God in the diversity of customs."
This is the concluding plea of *De Pace Fidei*. Cusa envisions a world where diversity of custom is accepted as long as the underlying unity of worship is maintained. He does not demand uniformity, but unity in diversity. It is a timeless call for ecumenism and interfaith understanding that resonates deeply in the modern world.
"To seek God is to be found by Him."
Finally, Cusanus assures the seeker that the very act of searching is evidence of God's presence. We could not seek God if He were not already influencing our will. The search itself is a response to a divine call. This quote offers profound encouragement, validating the spiritual journey as a reciprocal relationship between the soul and the Creator.
The Legacy of the Infinite
Nicholas of Cusa stands as a towering monolith at the gateway to modernity, casting a shadow that reaches far into the future. His philosophy was a bridge over which the Western mind crossed from the closed world of the Middle Ages to the infinite universe of the Renaissance and beyond. By championing the concept of *Docta Ignorantia*, he provided an antidote to intellectual arrogance that is more relevant today than ever. In an age of information overload, where data is often mistaken for wisdom, Cusanus reminds us that true understanding begins with the acknowledgment of mystery.
His influence permeates the work of giants who followed him. Giordano Bruno took Cusa’s "centerless universe" to its heretical conclusion of infinite worlds; Copernicus utilized Cusa’s arguments on the motion of the earth; and Descartes’ turn toward the subject owes a debt to Cusa’s view of the mind as a measurement of reality. Yet, beyond his scientific and philosophical contributions, Nicholas of Cusa remains a spiritual guide. He teaches us that the contradictions of life—the conflicts between faith and reason, unity and diversity, finite and infinite—are not problems to be solved, but mysteries to be embraced within the coincidence of opposites. His voice calls out across the centuries, inviting us to enter the "dazzling darkness" where the intellect falls silent, and the heart finds its rest in the infinite unity of God.

Giordano Bruno: The Martyr of Infinity
If Nicholas of Cusa opened the door to the infinite universe, Giordano Bruno kicked it off its hinges. A direct intellectual heir to Cusa, Bruno took the concept of a centerless cosmos and expanded it to include infinite worlds inhabited by other beings. His fiery passion and refusal to recant his expansive vision make him a fascinating, albeit more tragic, counterpart to Cusa’s diplomatic mysticism.
Meister Eckhart: The Mystic of Detachment
To understand the spiritual roots of Nicholas of Cusa, one must look to Meister Eckhart. A fellow German mystic from the century prior, Eckhart’s sermons on the "God beyond God" and the birth of the Word in the soul deeply influenced Cusa’s negative theology. Readers who appreciate Cusa’s focus on the ineffable nature of the divine will find a kindred spirit in Eckhart’s radical path of detachment.
Augustine of Hippo: The Architect of Faith and Reason
Nicholas of Cusa frequently cited "the divine Augustine" as his primary theological authority. Augustine’s explorations of the inner self, the nature of time, and the relationship between the finite soul and the infinite God laid the foundation upon which Cusa built his "learned ignorance." For a deeper dive into the synthesis of classical philosophy and Christian theology, Augustine is the essential starting point.
