Quick Answer
Thomas Aquinas (c. 1225-1274) was a Dominican friar and philosopher who produced the most comprehensive intellectual synthesis of the medieval West. His Summa Theologiae integrates Aristotelian philosophy with Christian theology through the Five Ways for God's existence, natural law ethics, the analogy of being, and a systematic treatment of faith and reason. Rudolf Steiner called his work the historical culmination of Aristotelian thinking, and dedicated an entire lecture course to him.
Key Takeaways
- The Dumb Ox who filled the world: Aquinas was physically large and quiet as a student. His teacher Albertus Magnus, when classmates mocked Thomas's silence, said: "You call him the Dumb Ox, but one day the bellowing of this ox will resound throughout the entire world." It proved accurate.
- The Five Ways: Aquinas's five proofs for God's existence from motion, causation, contingency, degrees of perfection, and final causality remain the most carefully constructed natural theology arguments in Western philosophy, still debated by contemporary analytic philosophers.
- Faith and reason: Aquinas insisted that faith and reason occupy distinct but complementary domains. Natural reason can demonstrate God's existence and unity. The Trinity, Incarnation, and sacraments require faith. This framework made philosophy a legitimate and positive tool for theology rather than a threat to it.
- Unfinished Summa: After a mystical experience in December 1273, Aquinas stopped writing and said "all that I have written seems to me like straw compared to what I have seen." The Summa Theologiae was never completed. He died three months later at around age forty-nine.
- Rudolf Steiner connection: Steiner dedicated GA 74 (The Redemption of Thinking, 1920) to Aquinas, recognizing him as the culmination of the Aristotelian philosophical stream while arguing that Thomism's placement of spiritual reality beyond direct cognitive access created the limitation that Anthroposophy was born to transcend.

The Dumb Ox: Early Life and Formation
Thomas Aquinas was born around 1225 at Roccasecca, a castle near Aquino in southern Italy, the seventh child of a minor noble family. His parents intended him for a prestigious career: at age five he was sent to the Benedictine abbey of Monte Cassino, where his family hoped he would eventually become abbot. Instead, at around age sixteen, he encountered the Dominicans, the Order of Preachers recently founded by Dominic de Guzmán. He joined them in 1244.
His family was not pleased. His brothers physically kidnapped him on the road to Paris and held him at Roccasecca castle for over a year. Family legend records that they sent a prostitute to tempt him out of his religious vocation, and that Thomas drove her away with a burning brand from the fireplace, then drew a cross on the wall with the charred wood and knelt before it. The story may be pious embellishment, but it captures something real about the man: he was not going to be persuaded by anything his family could put before him.
Albertus Magnus and the Formation of a Great Mind
After his family released him, Aquinas studied under Albertus Magnus (Albert the Great) first in Paris and then in Cologne, from approximately 1245 to 1252. Albertus was the greatest philosopher-scientist of the thirteenth century: he wrote systematic commentaries on virtually the entire Aristotelian corpus and on pseudo-Aristotelian and Arabic scientific works, covering natural science, metaphysics, ethics, and theology. He recognized immediately that Thomas was exceptional. When fellow students mocked Thomas's large, silent presence with the nickname "the Dumb Ox," Albert declared in lecture: "You call him the Dumb Ox. I tell you this Dumb Ox will bellow so loud that his bellowings will fill the world." Albert proved correct. Thomas would complete and perfect what Albert had begun: the Christianization of Aristotle as the philosophical framework for medieval Catholic theology.
Thomas taught at the University of Paris from 1252 to 1259, returned to Italy for ten years, went back to Paris from 1269 to 1272, and spent his last years in Naples. He died in March 1274 at the Cistercian abbey of Fossanova, on his way to the Second Council of Lyon, at approximately forty-nine years old. He was canonized by Pope John XXII in 1323, and his feast day is January 28.
The Five Ways: Proofs for God's Existence
The Five Ways (Quinque Viae) are presented in Summa Theologiae Part I, Question 2, Article 3. They are Aquinas's five arguments for God's existence from natural reason, without recourse to Scripture or revelation. They remain the most carefully constructed and most frequently discussed natural theology arguments in Western philosophy.
| Way | Starting Point | Argument | Conclusion |
|---|---|---|---|
| First Way: Motion | Things are in motion | Whatever moves is moved by something else; an infinite regress of movers is impossible | There must be an Unmoved Mover: God |
| Second Way: Causation | Things have efficient causes | Every cause is itself caused; an infinite regress of efficient causes is impossible | There must be an Uncaused First Cause: God |
| Third Way: Contingency | Some things exist contingently | Contingent things might not have existed; if nothing were necessary, nothing would exist now | There must be at least one Necessary Being: God |
| Fourth Way: Degrees of Perfection | Things have more or less of qualities (goodness, truth, nobility) | Degrees of perfection require a maximum from which lesser degrees derive | There must be a Maximum Being, most fully good and real: God |
| Fifth Way: Teleology (Design) | Natural things without intelligence act toward ends regularly | Things without intelligence cannot act toward ends unless directed by something intelligent | There must be an intelligent being directing all things: God |
A common misreading of the Five Ways treats them as empirical arguments from design, like Paley's watchmaker argument. They are not. They are metaphysical arguments that use empirical observations (things move, things cause things, things are contingent) as starting points for analyses of causation, actuality, potentiality, and being. The argument is not "the universe looks designed, therefore there is a designer." It is "the existence of any contingent thing at all requires a being whose existence is self-explanatory, and such a being must be what we call God."
Contemporary Debates About the Five Ways
The Five Ways continue to generate serious philosophical discussion. The Third Way has been reconstructed by contemporary Thomists such as Germain Grisez and Brian Davies in ways that respond to standard objections. The Second Way anticipates what contemporary philosophers call the cosmological argument, and its relation to the Kalam cosmological argument (developed by Islamic philosophers and recently defended by William Lane Craig) is actively debated. The Fourth Way, the most Platonic of the five, has been defended by Norris Clarke and others as a version of the argument from participation. The philosophical debate is genuinely live, not merely historical. Most contemporary analytic philosophers who discuss the arguments are not convinced by them, but the objections are not as straightforward as introductory philosophy textbooks suggest.
Faith and Reason: Two Wings of the Same Bird
The relationship between faith and reason is the organizing question of Aquinas's entire intellectual project. He inherited a tense situation. On one side, certain theologians (particularly in the Augustinian tradition) were suspicious of Aristotelian philosophy as pagan and potentially corrupting to faith. On the other side, some interpreters of Aristotle through the Arabic commentator Averroes seemed to teach doctrines, particularly the mortality of the individual soul and the eternity of the world, that conflicted with Christian teaching.
Aquinas's response was to draw a careful distinction between the domains of natural reason and faith. Natural reason, operating through philosophical methods, can demonstrate some truths about God: that God exists, that God is one, that God is good, simple, and intelligent. These are "preambles of faith," truths accessible to reason that faith also affirms and that prepare the mind to receive revealed truth.
The Boundary Between Reason and Faith
Above the reach of natural reason lie the "mysteries of faith": the Trinity (one God in three Persons), the Incarnation (the Second Person becoming human), the resurrection of the body, and the sacraments as means of grace. These cannot be demonstrated by natural reason. They are not against reason (which would make them irrational) but above it (which makes them super-rational). Faith is not a substitute for reason where reason fails. It is an extension of human knowing into territory that reason, left to its own capacities, cannot enter. This careful cartography of faith and reason's respective territories was one of the most consequential intellectual achievements of the medieval period. It enabled a positive rather than suspicious relationship between philosophy and theology, and it allowed the full Aristotelian apparatus to be deployed in service of theological inquiry without the anxiety that philosophical method was undermining revealed truth.
Natural Law: The Ethics of Human Nature
Aquinas's natural law ethics is one of his most influential and most actively applied contributions. It has shaped Western jurisprudence, Catholic social teaching, medical ethics, and political philosophy from the thirteenth century to the present.
The framework begins with eternal law: God's rational governance of the entire created order. Every creature participates in eternal law through its own nature, inclining toward the ends proper to its kind. Rational creatures participate consciously: through reason, human beings can discern the natural inclinations implanted in their nature and understand them as directives toward the good.
| Type of Law | Definition | Scope | Known How |
|---|---|---|---|
| Eternal Law | God's rational governance of all creation | Everything that exists | Fully only by God; partially through its effects |
| Natural Law | Rational creature's participation in eternal law through natural inclinations and reason | All rational beings | Through natural reason; knowable without revelation |
| Human Law | Positive law derived from natural law for specific communities | Particular societies | Through human legislative institutions |
| Divine Law | Revealed law in Scripture, needed to guide humanity toward supernatural end | Those with access to revelation | Through Scripture and tradition |
The first precept of natural law is "do good and avoid evil." From this, secondary precepts follow by looking at the basic natural inclinations: the inclination to preserve life (basis for the wrongness of murder and the permissibility of self-defence), the inclination to reproduce and raise children (basis for sexual ethics and family law), the inclination to live in society (basis for justice and political authority), and the inclination to know truth about God (basis for religious obligation).
Contemporary critics sometimes argue that Aquinas's natural law commits the naturalistic fallacy: inferring what ought to be from what is. His defenders (particularly contemporary neo-Thomists in the "New Natural Law" school: John Finnis, Germain Grisez, Joseph Boyle) argue that Aquinas is not moving from "is" to "ought" in a simple way but from the recognition of basic human goods, which are self-evidently valuable, not derived from mere biological facts, to moral norms that follow from taking those goods seriously. The debate continues in contemporary moral philosophy.
Hylomorphism and the Structure of Reality
Aquinas adopted Aristotle's doctrine of hylomorphism (matter-form composition) as his basic metaphysical framework and applied it to theology. Every physical substance is composed of matter (the principle of potentiality and individuation) and form (the principle of actuality and intelligibility). Together they constitute one substance, not two things joined.
The application to theology is elegant. God is pure form without matter: pure actuality with no potentiality whatsoever. This is why God cannot change (change requires potentiality, which God lacks), cannot suffer (suffering is the actualization of a potentiality for being harmed), and is not in time (time is the measure of change, and God does not change). Angels are pure forms without matter but are not pure actuality: they have the potentiality to receive information (to "think of" different objects at different times) and the potentiality to exist or not exist. They are therefore contingent beings, though immaterial.
The Human Soul in Aquinas's Hylomorphism
For Aquinas, the human soul is the "form of the body," in Aristotelian terms. It is not a separate substance trapped in the body (Plato's view) but the organizing principle that makes this body a human body. The soul and body are not two things but one thing: the human being. This has practical implications for Aquinas's ethics: the body is not a prison from which the soul escapes at death but an integral part of human nature. The resurrection of the body is therefore not optional or merely symbolic for Aquinas: it is required by his anthropology. The disembodied soul between death and resurrection is, for Aquinas, in an incomplete state, awaiting the restoration of the full human nature. This contrasts with Platonic and Gnostic frameworks in which the soul's liberation from the body is the goal, and it has implications for how spirituality relates to bodily life.
The Analogy of Being: Speaking of God Without Error
The analogy of being is Aquinas's solution to one of the most persistent problems in philosophical theology: how can human language, which is formed in the context of finite, material experience, be used to speak meaningfully about an infinite, immaterial God?
Aquinas rejects two extreme positions. Univocal predication (using terms in the same sense of God and creatures: "God is good" and "this person is good" mean the same thing) fails because God's goodness is radically different from creaturely goodness. Equivocal predication (terms mean completely different things: "good" of God and creatures is like "bank" meaning a river bank and a financial institution) makes theology meaningless: if "God is good" and "this person is good" have nothing in common, the first statement tells us nothing.
Analogy: Between Univocal and Equivocal
Analogy means that a term is applied to two things in ways that are neither identical nor completely different but related by a proportion or participation. "Healthy" applies primarily to a healthy organism. Derivatively it applies to food (healthy food is that which produces health), to a complexion (a healthy complexion is that which indicates health), to medicine (healthy medicine is that which restores health). These uses are related but not identical. Similarly, "good" applies primarily to God, who is goodness itself, the source and standard of all goodness. Creaturely goodness participates in divine goodness by resemblance. The term applies to creatures in a secondary and derived sense. This is analogical predication. It allows theological language to be meaningful without claiming that we know God as we know creatures. Aquinas's analogy doctrine became one of the most contested concepts in twentieth-century Catholic theology, with Karl Barth rejecting it entirely as a Catholic error and Hans Urs von Balthasar defending it as the foundation of all theological aesthetics.
The Summa Theologiae: A Cathedral in Words
The Summa Theologiae, begun around 1265 and left unfinished at Aquinas's death in 1274, is the greatest single achievement of medieval philosophy and theology. It was written, as Aquinas states in the prologue, for "beginners" in theology, though the "beginners" he envisioned were already trained in philosophy and needing systematic grounding in theology.
The work is organized through a question-and-answer format that is itself philosophically rigorous. Each article asks a question (whether God exists, whether the soul is immortal, whether lying is ever permitted), states objections to the correct answer, gives the correct answer with its reasons, and then responds to each objection individually. This format, developed in the medieval schools as a pedagogical tool, became in Aquinas's hands a precision instrument for philosophical analysis.
The Summa comprises three Parts. Part I (Prima Pars) treats God in himself, the procession of the divine Persons, the creation, angels, and the human being. Part II, divided into two sections, treats the return of the rational creature to God: IaIIae covers general principles of morality (the nature of human acts, passions, virtues, law, and grace), and IIaIIae covers the specific virtues and vices in detailed treatment. Part III (Tertia Pars) treats Christ and the sacraments, the way by which the human being actually returns to God. The Tertia Pars was left incomplete.
All That I Have Written Is Straw
On the feast of Saint Nicholas, December 6, 1273, Thomas Aquinas was celebrating Mass in Naples when something happened. His secretary Reginald of Piperno, who was present, later recorded that after the Mass, Thomas fell silent and stopped writing. He never wrote again. When Reginald urged him to continue the Summa, Thomas said: "Reginald, I cannot, because all that I have written seems to me like straw" (mihi videtur ut palea).
What happened that morning has been debated ever since. The most straightforward reading is that Thomas experienced a mystical vision so overwhelming that his entire previous intellectual work seemed inadequate by comparison. This interpretation fits the pattern of the mystical tradition: the contemplative who, after years of disciplined theological work, is finally granted direct experience of what the work had been pointing at, and finds the work itself diminished by the encounter.
"I adjure you by the living almighty God, and by the faith you have in your order, and by charity, that you never reveal in my lifetime what I tell you. Everything that I have written seems to me like straw by comparison with what I have seen and what has been revealed to me." (Thomas Aquinas to Reginald of Piperno, December 1273, as recorded by William of Tocco)
Three months later, traveling to the Council of Lyon, Thomas hit his head on a fallen tree branch and died at the Cistercian abbey of Fossanova on March 7, 1274. He was approximately forty-nine years old. The Summa Theologiae was unfinished. His disciples completed it, using his earlier Scriptum super Sententias to fill the gap in the Tertia Pars, but the work as Aquinas left it ends mid-sentence in the treatment of the sacrament of Penance.
The phrase "mihi videtur ut palea" is the most philosophically suggestive moment in Aquinas's biography. It raises the question: what had this man, who had organized the whole of Christian theology with extraordinary rigor and precision, suddenly seen that made all of it look like straw? He never said. The silence at the end of the greatest theological synthesis of the medieval West is one of the most resonant moments in the history of spirituality.
Rudolf Steiner and the Redemption of Thinking
Rudolf Steiner dedicated an entire lecture course to Thomas Aquinas: The Redemption of Thinking: A Study in the Philosophy of Thomas Aquinas (GA 74, Dornach, 1920). This reflects how seriously Steiner took Aquinas's achievement. He did not dismiss Scholastic philosophy as merely ecclesiastical. He engaged it as a genuine philosophical accomplishment that deserved careful evaluation.
Steiner's assessment is a respectful critique in three movements. First, he acknowledges that Aquinas achieved the most complete synthesis possible within the framework he inherited: the full integration of Aristotelian natural philosophy, Aristotelian logic and metaphysics, and Christian revealed theology. This synthesis was the culmination of a historical process that began with Aristotle's systematization of Greek philosophy and continued through the Arabic commentators and the earlier Scholastics. As a synthesis, it stands as a remarkable achievement.
The Historical Importance of Thomism in Steiner's Philosophy
Steiner did not simply criticize Aquinas. He traced what he called the Aristotelian-Thomistic stream in esoteric history, arguing that many souls who had worked in Aristotle's school in the fourth century BC reincarnated in the medieval period and worked through the Scholastic synthesis, and that these same souls were active in the Anthroposophical movement in the nineteenth and twentieth centuries. This is a characteristic Steinerian move: placing individual intellectual achievements within a larger picture of soul development across incarnations. In this framework, Thomism is not an error to be corrected but a necessary historical achievement that prepared the ground for something further. The Scholastics built the conceptual framework; the Anthroposophists were to fill it with the content of direct spiritual experience. The relationship is not opposition but succession.
Second, Steiner identifies the fundamental limitation of Thomism: it places spiritual reality beyond the reach of direct cognitive experience. For Aquinas, natural reason can demonstrate God's existence and certain divine attributes, but the inner life of God, the Trinity, the purposes of Providence, the nature of grace and redemption, these are knowable only through faith in divine revelation. The spiritual world is not directly accessible to human knowing; it is accessible through authoritative testimony (Scripture, tradition, the Church) accepted by faith.
For Steiner, this was a historically necessary protective measure. In the thirteenth century, direct supersensible experience was not safely achievable through the ordinary intellectual development of the time. Thomism's placement of spiritual reality beyond direct cognitive reach prevented premature, distorted, or demonic claims to spiritual knowledge. It was a guardrail appropriate to the period.
But, Steiner argues, this guardrail had, by the twentieth century, become a wall. The consciousness soul epoch (from approximately 1413 onward) progressively developed in the Western human being the capacity for individual, self-standing cognitive activity. By Steiner's time, this development had reached the point where thinking itself, properly transformed through the practices he describes in How to Know Higher Worlds (GA 10), could become an organ of direct spiritual perception, not merely of logical inference. This transformed thinking is what Steiner calls the "redemption of thinking": the transformation of ordinary discursive thought, which Aquinas used masterfully to establish what reason can know about God, into Imagination, Inspiration, and Intuition, the three stages of supersensible cognition that allow direct experience of the spiritual world.
The title of Steiner's lecture course is therefore precisely chosen. "The Redemption of Thinking" means the freeing of thinking from its confinement within logical inference about the spiritual world, and its transformation into a capacity for direct encounter with the spiritual world. Aquinas was the master of thinking in its pre-redemption state. Anthroposophy proposes to carry that thinking one step further.

Who was Thomas Aquinas?
Thomas Aquinas (c. 1225-1274) was a Dominican friar, theologian, and philosopher who produced the most comprehensive intellectual synthesis of the medieval West. Born near Aquino in southern Italy, he studied under Albertus Magnus in Cologne and Paris. His major work, the Summa Theologiae, integrates Aristotelian philosophy with Catholic theology through the Five Ways, natural law ethics, the analogy of being, and a systematic treatment of every major theological question. He was canonized in 1323 and remains the foundational thinker of Catholic intellectual tradition.
What are the Five Ways of Thomas Aquinas?
The Five Ways are Aquinas's five arguments for God's existence from natural reason, presented in Summa Theologiae I.2.3. The First Way argues from motion to an Unmoved Mover. The Second from efficient causation to an Uncaused First Cause. The Third from contingency to a Necessary Being. The Fourth from degrees of perfection to a Maximum Being. The Fifth from the directedness of unintelligent natural things toward ends to an intelligent directing being. They are metaphysical rather than purely empirical arguments, and they remain actively debated by contemporary analytic philosophers.
What is natural law in Thomas Aquinas?
Natural law is the rational creature's participation in eternal law (God's rational governance of creation) through the natural inclinations implanted in human nature. The first precept is "do good and avoid evil." Secondary precepts follow from basic human inclinations: preserving life, reproducing and educating offspring, living in society, and knowing truth about God. Natural law is accessible to all rational beings through reason, without revelation. It forms the basis of Aquinas's ethics and has influenced Western jurisprudence, Catholic social teaching, and political philosophy for seven centuries.
What is the Summa Theologiae?
The Summa Theologiae (1265-1274) is Aquinas's systematic treatment of Catholic theology in three Parts: Part I on God and creation, Part II on morality and the virtues, Part III on Christ and the sacraments. Written in question-and-answer format through the medieval disputatio method, it was left unfinished after Aquinas stopped writing following a mystical experience in December 1273. It remains the most comprehensive and most systematically organized treatment of Christian theology in the Western tradition.
What is faith and reason in Thomas Aquinas?
Aquinas distinguished two complementary domains. Natural reason can demonstrate certain truths about God: existence, unity, simplicity, goodness. These are "preambles of faith." Above natural reason lie the mysteries of faith (Trinity, Incarnation, sacraments), which are not against reason but beyond it. Faith is not a substitute for reason where reason fails but an extension of human knowing into territory reason cannot enter alone. This framework made philosophy a legitimate positive tool for theology and shaped Western intellectual culture through the sixteenth century and beyond.
What is hylomorphism in Aquinas?
Hylomorphism is Aristotle's doctrine that all physical substances are composed of matter (potentiality, individuation) and form (actuality, intelligibility). Aquinas applies it theologically: God is pure form without matter, pure actuality with no potentiality, which is why God cannot change or suffer. Angels are pure forms without matter but not pure actuality. Human beings are form-matter composites, which is why the resurrection of the body matters: the soul without the body is incomplete. The body is not a prison from which the soul escapes but an integral part of human nature.
What is the analogy of being in Aquinas?
The analogy of being solves the problem of how to speak meaningfully about God when God radically transcends all creaturely categories. Terms like "good" or "wise" apply to God neither univocally (in exactly the same sense as creatures) nor equivocally (in completely different senses), but analogically: God is good in a primary and eminent sense from which creaturely goodness derives by participation. This allows theological language to be meaningful without claiming we know God as we know creatures. Karl Barth rejected it; Hans Urs von Balthasar made it the foundation of theological aesthetics.
Why did Aquinas stop writing the Summa Theologiae?
On December 6, 1273, after celebrating Mass in Naples, Aquinas stopped writing entirely and never wrote again. When his secretary Reginald urged him to continue, Thomas said: "All that I have written seems to me like straw compared to what I have seen." Whether this was a mystical vision or a physical event (possibly a stroke) remains debated. He died three months later at approximately forty-nine, on his way to the Council of Lyon. The Summa was left unfinished. The phrase "mihi videtur ut palea" is one of the most haunting in the history of philosophy.
What did Rudolf Steiner say about Thomas Aquinas?
Steiner dedicated GA 74 (The Redemption of Thinking, 1920) to Aquinas, recognizing him as the culmination of the Aristotelian philosophical stream. His critique: Thomism placed spiritual reality beyond direct cognitive access, accessible only through faith. This was historically necessary protection against premature spiritual claims, but it eventually became limiting. Anthroposophy's "redemption of thinking" refers to transforming ordinary discursive thought into an organ of direct spiritual perception, going where Aquinas's framework stopped. Steiner also held that many Scholastic souls reincarnated in the Anthroposophical movement.
How does Aquinas connect to spiritual development?
Aquinas's theology of the beatific vision (the soul's direct knowledge of God as the ultimate human end) describes the highest spiritual state as direct cognitive union with divine reality. This is not achieved in ordinary life but is the goal toward which the entire moral and spiritual life is oriented. Steiner, while arguing that Thomism blocked premature spiritual development, also recognized the Thomistic virtues, particularly the cardinal virtues (prudence, justice, fortitude, temperance) and the theological virtues (faith, hope, charity), as providing the moral foundation without which higher spiritual development is dangerous. The Thomistic moral framework and the Anthroposophical spiritual development path are not opponents but sequential stages.
How does Thomas Aquinas connect to Steiner's Anthroposophy?
Steiner's relationship to Aquinas is one of respectful critique. In GA 74 (The Redemption of Thinking), Steiner argues that Aquinas's greatest achievement, the systematic reconciliation of faith and reason, also created Western Christianity's most persistent limitation: a framework in which spiritual reality is accessible only through inference and faith, not through direct cognitive experience. Anthroposophy proposes to redeem thinking by transforming it from an instrument of logical inference into an organ of spiritual perception, going where Aquinas's framework stopped. Steiner also noted the importance of the Aristotelian-Thomistic stream in esoteric history: Steiner believed that many souls who had worked in Aristotle's school in antiquity reincarnated in the medieval period and worked through the Scholastic synthesis before incarnating again in the nineteenth and twentieth centuries to work in the Anthroposophical movement.
The Straw and the Vision
Thomas Aquinas spent his life building the most precisely organized intellectual structure that medieval Europe produced. He deployed Aristotelian logic, Neoplatonic metaphysics, Biblical theology, and the entire apparatus of Scholastic disputation to construct a system that addressed every theological question with care and rigor. And then, on a morning in December 1273, he stopped. Something happened that made the whole structure look like straw. He never said what it was. The silence at the end of his life is its own kind of teaching: that the systems and arguments we build, however good and necessary, are not the destination. What he encountered in Naples that morning was. The building of the system and the going beyond it are both necessary. Aquinas did both, in sequence, and in so doing showed something about the shape of genuine intellectual and spiritual development.
