A history of the places

Rome and the schools

Cicero received it in 84 BC and translated the Greek topoi into the Latin loci. The word carries the meaning. A locus is a place, a seat, a location. Cicero's Topica and De Inventione did for Roman oratory what Aristotle had done for Greek dialectic: they gave the law court, the senate, and the forum a methodology. The orator who masters the loci does not wait for arguments to occur to him. He walks through definition, through genus and species, through cause and effect, through comparison and opposition, and the arguments present themselves. Cicero's innovation was not the catalog. It was the insistence that the catalog belongs to every educated mind, not only to philosophers.

Quintilian completed what Cicero began. In the Institutio Oratoria, written around 95 AD, he codified the loci into the school curriculum. Every Roman boy who received a serious education received the places alongside his grammar and his texts. The method became institutional, which is how methods survive.

Three hundred years later, Augustine arrived at Rome from Carthage as a teacher of rhetoric. He was, before his conversion, a professional Ciceronian. He knew the places. When he became a bishop and a theologian, he did not discard the rhetorical training; he redirected it. De Doctrina Christiana, written from 396 to 426, is a manual for reading and preaching Scripture that draws directly on the classical tradition. Augustine argued that the Christian preacher needs rhetoric the way a traveler needs a road: not the point of the journey, but the means of reaching it. The places passed from pagan into Christian use.

They passed into medieval theology through Peter Lombard. In Paris, around 1150, Lombard compiled the Sententiae in IV Libris Distinctae: the "Sentences." He sorted the whole body of Christian doctrine into four books by topic: the Trinity, creation, the Incarnation, the sacraments and last things. Under each he placed the relevant texts from Scripture and the Fathers. Every medieval theologian who wanted a master's degree had to lecture on the Sentences. Aquinas lectured on them. Bonaventure lectured on them. Scotus, Biel, Luther. The Sentences were the organizing principle of European theological education for four hundred years. The habit of sorting Christian teaching by loci was learned and relearned by every generation of students from 1150 to 1520.

The man nobody remembers

Rudolph Agricola was born in 1444 in Baflo, in Frisia. He studied at Zwolle, under the influence of Thomas à Kempis and the Brothers of the Common Life. He studied at Louvain, then Pavia, then the court of Ferrara. He completed De Inventione Dialectica libri tres (three books on dialectical invention) in 1479 at the court of Heidelberg. He died in 1485, before the work was ever printed.

What Agricola did in those three books cannot be overstated. He took the catalog of places inherited from Aristotle and Cicero and transformed its purpose. For the classical tradition, the places had been storage bins: you kept your arguments there and retrieved them on demand. Agricola made them into questions. He defined prudence in the proemium of Book I as "seeing what lies in each matter, and gathering its consequences and its contradictions, and to what each thing leads, and what may come of it." The places (definition, genus, difference, property, whole and parts, cause, end, effects, opposites, similars, comparables) were no longer slots into which arguments were filed. They were prompts, signa, the signs by which a mind is led through a topic until it has seen everything the topic contains. Agricola's complete list runs to twenty-four loci. They are still countable today in the 1539 Cologne edition.

The method did not stay in Heidelberg.

Agricola taught Alexander Hegius. Hegius became the rector of the school at Deventer. In the 1480s, a boy from Gouda named Erasmus attended the school at Deventer under Hegius. Agricola visited the school once while Erasmus was a student, and Erasmus remembered it for the rest of his life. Erasmus carried Agricola's method into every schoolroom in Europe through De Copia (1512), a rhetorical handbook that trained students in the habit of collecting under topical heads and enriching arguments from the places. He acknowledged the debt in writing. He named Agricola as the man who had shown northern Europe how to read.

Wittenberg

Philip Melanchthon was born in 1497, nine years after Agricola's death. He studied at Heidelberg, where he immersed himself in Agricola's writings, and at Tübingen, where he absorbed the humanist curriculum Agricola had helped shape. In 1518 he arrived at the University of Wittenberg as a twenty-one-year-old professor of Greek. Luther heard his inaugural lecture and wrote to a friend that this young man would surpass all the scholars in Germany.

In 1521, Melanchthon published Loci Communes Rerum Theologicarum. Luther called it the best book after Scripture for learning theology. The method was Agricola's. Melanchthon took the places (redefined now as doctrinal places, not dialectical ones) and asked of every passage in Scripture: which locus does this teach? He gathered the passages under the doctrines, organized the doctrines into a sequence, and produced the first systematic Lutheran theology. The order of the Small Catechism, published eight years later in 1529, is itself a loci structure: Ten Commandments, Creed, Lord's Prayer, Baptism, Confession, Lord's Supper. The places organize not only the theology but the catechesis.

In 1539, Melanchthon delivered a public oration honoring Agricola. The text survives in the Corpus Reformatorum, volume eleven. He credited Agricola as the man who had given the Reformation the intellectual instrument it required.

Three confessions, one method

The Anglican and Reformed traditions received the same structure through their own confessional documents. John Calvin's Institutes of the Christian Religion, first published in 1536 and expanded through 1559, organized all of Christian doctrine into four books covering the knowledge of God as Creator, Redeemer, the work of the Holy Spirit, and the church. It is a loci system. Calvin did not use Melanchthon's term, but the architecture is identical: classify what Scripture says on each subject, arrange those classifications so the reader can receive the whole of Christian teaching as a coherent body. Thomas Cranmer, who corresponded with Melanchthon and read the Lutheran confessions carefully, produced the Forty-Two Articles in 1553, later revised to the Thirty-Nine Articles of 1563. The organization follows the same topical pattern the Lutherans had established: the word loci does not appear, but the method is present in every article. Three confessional traditions, three sets of founding documents, one inherited structure.

The Lutheran inheritance

Martin Chemnitz studied at Wittenberg and spent his life as superintendent at Brunswick. His Loci Theologici, published posthumously in 1591, took Melanchthon's method and deepened it: more passages, more precision, more engagement with the patristic sources, more systematic treatment of each locus. It is said in Lutheran circles that if the second Martin had not come, the first Martin would have been lost.

Johann Gerhard held the chair at Jena from 1616 to 1637. His Loci Theologici fills nine folio volumes. Every locus receives its full scriptural grounding, its patristic attestation, its scholastic analysis, and its polemical defense. It is the summit of Lutheran Orthodoxy's doctrinal method.

Johann Andreas Quenstedt, Wittenberg, 1685. His Theologia Didactico-Polemica is the last major monument of classical Lutheran scholasticism. The method has not changed from Melanchthon's 1521 first edition. The body of doctrine has grown; the structure is the same.

Reformed and Puritan

The Puritan tradition took a different path toward the same destination. Pierre de la Ramée (Ramus) published his Dialectica in 1555 and reorganized the classical loci into binary dichotomies that could be printed on a single page. Ramism is not a deepening of the method; it is a simplification. But it traveled fast. William Perkins received it at Christ's College, Cambridge, under Laurence Chaderton. Perkins's Arte of Prophecying (1592) is a Ramist account of how to preach: take the text, identify the doctrine, state it, apply it to the cases of conscience. The places have become the sermon outline. William Ames, Perkins's student, became a professor at Franeker and published Medulla Theologica (1623), which organized Reformed doctrine under topical heads drawn directly from the loci tradition. Ames's book was assigned as the theology textbook at Harvard College in its first century.

John Cotton trained at Emmanuel College, Cambridge, under the direct Puritan-Ramist tradition. He emigrated to Massachusetts Bay in 1633. Jonathan Edwards entered Yale in 1716 and began his theological notebooks, the Miscellanies, at nineteen. The notebooks are a massive loci document: numbered entries organized by subject, Scripture passages gathered under doctrinal heads, connections drawn across the whole body of Christian teaching.

Charles Hodge at Princeton published his three-volume Systematic Theology in 1871. The structure is the loci structure: doctrine by doctrine, passage by passage. He was explicit that the theologian's task is to collect and organize what Scripture teaches, as a naturalist collects and classifies specimens. Geerhardus Vos built the discipline of biblical theology at Princeton by tracing the progressive revelation of doctrinal categories through the canonical order. The Old Princeton method was topical, systematic, and driven by the same conviction Melanchthon had carried to Wittenberg: Scripture teaches doctrine, and the theologian's task is to find where.

A parallel discovery

In the twentieth century a parallel stream developed, independently, in American evangelicalism. William Rainey Harper trained Wilbert Webster White, who founded the Biblical Seminary in New York in 1900 and built a curriculum around direct inductive observation of the text. Robert Traina refined the method into a formal discipline at Asbury Theological Seminary, where it has been taught and transmitted to the present day. The questions this movement asks (Who? What? When? Where? Why? How?) are structurally the same questions Agricola's twenty-four loci were designed to supply. White did not know Agricola; he arrived at the same posture by a different road. The convergence is real. The genealogical connection is not.

Daniel Fuller developed arcing at Fuller Theological Seminary in Pasadena in the 1960s and 1970s. Where the classical method asked what a topic's cause and effect and opposition are, Fuller's arcing asked how each clause in a passage supports, grounds, or qualifies the clause that follows it. The places applied not to the content of a doctrine but to the structure of an argument. The same underlying discipline: get under the material, ask what is there, follow it where it leads.
