Compulsory schooling for all 5- to 13-year-olds was introduced across Prussia on 12 August 1763 by Frederick II with the General-Land-Schul-Reglement. His father Frederick William I had already imposed compulsory schooling on the royal domains in 1717. Prussia thus had a comprehensive state-mandated school system roughly a hundred years before the rest of Europe. The official aims were modest: reading, writing, Christian instruction. The structural effects – administrative personnel, military reserve, disciplining of the peasantry, leading the population away from "superstition" toward an Enlightenment-sanctioned worldview – were the actual programme. In 1810 this programme was philosophically reframed by Humboldt's reform, but the form remained: lesson clock, class group, curriculum as filter. Through Horace Mann it moved to the United States in 1843 and from there into most Western and East Asian school systems. This article lays out the historical architecture and ends on the point that is relevant for our platform: what stands in a curriculum and what does not stand in it is not distributed by chance. Both are filtered – and in the same direction.
1717 and 1763 – who introduced what
The father, the soldier-king Frederick William I, on 28 September 1717 issued the so-called Verordnung wegen Einführung der allgemeinen Schulpflicht in Preußen. It applied only to the royal domains and was patchy in practice. But the claim was on the table: every child whose parents lived within the king's reach should go to school. The background was a mixture of Pietist educational claim (every Christian must be able to read the Bible) and mercantilist reason of state (a literate and numerate population serves the state).
The son, Frederick II "the Great", enforced the programme across the whole kingdom 46 years later. The General-Land-Schul-Reglement of 12 August 1763 (full text in the collection of German History in Documents and Images, GHDI) required in § 1 the school attendance of all children from 5 to 13 years of age and threatened in § 10 sanctions against parents who failed to comply. It further regulated teacher training, school buildings, the timetable, the curriculum and the financial responsibility of landowners and parishes. With this text – drafted by the Silesian reform pedagogue Johann Julius Hecker on the king's commission – the modern German Volksschule begins.
What the regulation literally required
Three subjects of instruction are explicitly named in the regulation: reading, writing, Christian instruction. Nothing more. Arithmetic was foreseen in § 18 as a desirable addition, but not as compulsory. Natural history, history, geography, foreign languages, the "liberal arts" – none of these were on the compulsory programme of the elementary school. That was the business of the higher schools (Gymnasium) and of the university, that is, of a thin elite layer that bore no serious proportion to the population at large.
Teachers in the early phase were almost always untrained craftsmen, retired soldiers or church sextons who taught on the side. Hecker therefore established the first Prussian teacher seminary in Berlin in 1748, from which over decades trained teachers for the elementary schools emerged. For the time this was a major state investment. It is important to see that Prussia not only legislated compulsion but built the infrastructure to back it.
What did not stand in the regulation – the structural functions
The official subjects do not explain why an absolutist state introduced the elementary school. The structural functions that the historian James Van Horn Melton in his Cambridge study Absolutism and the Eighteenth-Century Origins of Compulsory Schooling in Prussia and Austria (1988) identifies as the real motives are:
- Administration. A Prussian official apparatus that collects taxes, keeps files, issues patents and organises military levies needs a literate and numerate population. Without comprehensive literacy no modern tax state.
- Military. From 1733 Frederick's army was organised under the canton system: every regiment had a fixed geographic catchment area from which it drew its recruits. A male village population literate in writing was substantially more useful for military orders, written service regulations and logistics than an illiterate one.
- Discipline. Six days a week, four to eight hours daily, for several years the school day accustoms the child to a rhythm that corresponds to that of the manufactory, the barracks and the office: fixed start time, sitting in an assigned place, silence unless called on, teacher authority, written sanctions for deviation. This habituation to form is – independent of content – the most lasting result of Prussian schooling. Michel Foucault described this logic in Discipline and Punish (1975) as the modern disciplinary power: school, barracks, factory and hospital share the same architectural principle.
- Leading away from "superstition". The Enlightenment was Frederick's self-understanding. What he called "superstition" comprised a wide variety: popular piety, witchcraft beliefs, ghost stories, magical healing methods, popular astrology, but also (and this is often forgotten today) any religious enthusiasm that withdrew from state supervision. The school was not meant to lead to scientific knowledge – that was the university's business – but to a state-sanctioned, Lutheran-Enlightenment middle. The regulation speaks in § 1 expressly of redeeming the children "from ignorance and the often deeply rooted superstition that goes with it".
These four functions are not secret but openly spoken in the contemporary administrative language. What historical research in the 20th century has added is only the sober analysis that these functions – not reading, writing and Christianity alone – were the actual structural programme of the elementary school, and that the form in which schooling still takes place today emerged from this bundle of functions.
The Humboldt break of 1810 – different idea, same framework
After the Prussian collapse at the battle of Jena (1806), Wilhelm von Humboldt, as section chief in the Ministry of the Interior, in 1809/10 reorganised the entire educational system. His programme is humanistic, anti-utilitarian, idealist. Education is for Humboldt an end in itself, not state service. It is to lead the human being to "the highest and most proportional formation of his powers", not to the usable subject. The Gymnasium is built up in its present form, the Berlin University (today the Humboldt University) founded in 1810, the Abitur formalised as the entry to higher education.
In content this is a sharp break with Frederick. Structurally it is not. The elementary school remains eight years long, six days a week, class group, lesson clock, grading scale. Humboldt changes the why, not the how. The school day into which a German child grows in 1850, 1900, 1950 and 2020 is essentially the Prussian form of 1763, with humanistically accented content in the upper-layer segment. Anyone who wants to change the system must see this double layer: an idealist educational ideal over an absolutist disciplinary framework.
This formal stability has held against at least four ideological overlays: Wilhelm II's school decree of 1889 and the 1892 curriculum reform as nationalist-anti-socialist loading; the Weimar Reichsschulkonferenz of 1920 and the Prussian guidelines of 1925 under Carl Heinrich Becker as a reform-pedagogical window of opening; the National Socialist Gleichschaltung from 1933 as ideological appropriation; and after 1945 the sharp split between the centralist GDR unified system (Education Act 1965) and the federal West German model with Methodenfreiheit for teachers, which after the PISA shock of 2000 transitioned into today's competence orientation with KMK educational standards (from 2003). In none of these phases were class group, lesson clock, grading scale or curriculum-as-filter touched.
The international export – Horace Mann in 1843
In 1843 the American school reformer Horace Mann, Secretary of the Massachusetts Board of Education, travels through Europe for seven months and studies above all the Prussian system. His travel report – the famous Seventh Annual Report (1844) – becomes the blueprint for the introduction of the US common schools: state-run, free, mixed-denomination, compulsory schools for all. By 1918 all US states had compulsory schooling. The form was the Prussian one.
In 1872 Meiji-Japan adopts the Prussian model almost verbatim in its Gakusei reform as part of its modernisation programme; Prussian educational experts advise directly in Tokyo. Via the United States and Japan, and via the direct Prussian succession in the German Empire and the Weimar Republic, the model has become the worldwide standard form. The post-war UNESCO compulsory-schooling standards rest organisationally on the same form. John Taylor Gatto traced this import path in detail in The Underground History of American Education (2001).
What has remained to this day
A German schoolchild in 2026 sits in a class group (Prussian), follows a fixed lesson clock with 45-minute units (Prussian in the variant that consolidated around 1880), is graded on a 1–6 scale (Prussian, formalised in the 19th century), moves through a prescribed age-graded sequence (Prussian), receives a largely centrally standardised curriculum (Prussian, today a matter of the federal states, but in idea and form identical), and is qualified by a state-recognised certificate on leaving the system (Prussian, formalised in the 19th century). These six features of form are part of what is called institutional path dependency: they are so deeply built into the architecture that they are no longer perceived as "decisions" but as "school itself".
Reform movements since Maria Montessori, Rudolf Steiner, the German Reformpädagogik of the 1920s, the anti-authoritarian school of the 1970s, the Freinet and Sudbury schools have each tried to break through one or more of these features of form. They have been able to establish themselves as replacement schools (Article 7 § 4 of the German Basic Law) – in Germany today about 3,700 state-recognised replacement schools plus about 1,900 supplementary schools, together around 10 % of all schools. The main body remains Prussian.
Connecting to the 1906 pattern – what is cut and what is missing
For our platform the historically interesting question is not what a state curriculum transmits but how it filters – in both directions. In our series The 1906 Pattern we showed that academic science in the narrow window 1906–1910 institutionally removed the subject "consciousness and non-material reality" from the canon – not through new data, but through institutional path dependency. In the schoolbook this filtering shows up in two forms: among the pre-1906 canonical figures as truncated biographies, among the post-1906 voices as missing biographies.
Before 1906 – the biographies are in the book, but cut
The leading natural scientists of the 16th to 19th centuries are present in every German schoolbook. What is practically absent from the school version is the half of their work that today would be classed as "metaphysical", "religious", "hermetic" or "occult" – although it not only belonged to their work in their own time, but in some cases made up the larger part of it by volume. This is not a marginal detail dropped for reasons of curricular space:
- Kepler: the three planetary laws in the schoolbook; not in the book: around 800 horoscopes, the court astrologer posts in Prague and for Wallenstein, the defence of his own mother in the Leonberg witch trial. See Kepler – court astrologer and founder of modern astronomy.
- Newton: mechanics, gravitation, optics in the schoolbook; not in the book: roughly one million words in his own hand on alchemy, apocalyptic theology and the hermetic tradition – more than the Principia, the Opticks and his mathematical writings combined. See Newton – alchemist and magician behind the mathematician.
- Boyle: Boyle's law in the schoolbook; not in the book: his testamentary Boyle Lectures for the public defence of Christianity against atheism, whose first series took place in London in 1692 and which continue to this day. See Boyle – chemistry, alchemy and the Boyle Lectures.
- Faraday: electromagnetic induction and the field concept in the schoolbook; not in the book: his lifelong membership as an elder of a small Christian splinter group (Sandemanians) and his refusal of the offered Royal Society presidency on religious grounds. See Faraday – Sandemanian and the field concept.
- Maxwell: the four Maxwell equations in the schoolbook; not in the book: his inaugural address as Cavendish professor (October 1871), in which he explicitly refused to have the physical model mistaken for the whole of reality – the corresponding passages have been cut from practically all standard excerpts of the speech. See Maxwell – theology and electrodynamics.
- Kelvin: the second law of thermodynamics and the Kelvin scale in the schoolbook; not in the book: his explicit, lifelong faith and his own grounding of the thermodynamic argument in that faith. See Kelvin – thermodynamics and faith.
- Pierre Curie: 1903 Nobel Prize with Marie Curie and Becquerel for radioactivity, piezoelectricity, the Curie temperature in the schoolbook; not in the book: his intensive participation in the Palladino sittings at the Institut Général Psychologique in Paris 1905/06 (together with Charles Richet, Henri Poincaré, Jean Perrin), his letter to Georges Gouy with the line that "a whole domain of entirely new facts" was opening up, his death on 19 April 1906 as the anchor of the entire 1906 pattern. See Pierre and Marie Curie and the medium Eusapia Palladino.
In all seven cases this is not a marginal detail. It is a portion of the work that was central in its own time, in some cases the larger portion by volume, and that today is systematically absent from the schoolbook – across centuries, disciplines and confessions, in the case of the undisputed canonical figures of modern natural science. The second half of the biography was not forgotten; it was filtered. Pierre Curie's death date 1906 marks the immediate transition into the next layer of the pattern – the layer in which the biographies are no longer in the book at all.
After 1906 – the biographies are absent altogether
A German upper-secondary physics book in 2026 contains Heisenberg, Schrödinger, Bohr, Einstein, Planck, perhaps Feynman. What is practically never found are the writings in which those same physicists addressed the problem of consciousness:
- Max Planck's Observer interview of 25 January 1931 with J. W. N. Sullivan ("I regard consciousness as fundamental. I regard matter as derivative from consciousness") and his lecture Religion und Naturwissenschaft (Baltic region, May 1937, printed by Barth in Leipzig 1938 ff.) – not present in the curriculum.
- Erwin Schrödinger's Vedantic writings My View of the World, What is Life?, Mind and Matter – not present in the curriculum.
- Werner Heisenberg's autobiographical Physics and Beyond and the manuscript Ordnung der Wirklichkeit on the "central order" – not present in the curriculum.
- John Eccles' Nobel-laureate synapse work is in the biology curriculum; his dualist late work The Self and Its Brain (with Karl Popper, 600 pages) and his 1992 quantum-mechanical mind-brain model in PNAS – not present in the curriculum.
- Roger Penrose's 2020 Nobel Prize for the singularity theorems is in the curriculum; his Orch-OR theory of consciousness with Stuart Hameroff from 1996 – not present.
- William James'sPrinciples of Psychology is the birth certificate of academic psychology; his 25-year investigation of the medium Leonora Piper, his two-time SPR presidency and his essay The Final Impressions of a Psychical Researcher (1909) – not present in the curriculum.
Curriculum filtering is only one of several parallel mechanisms by which the 1906 pattern has institutionally sustained itself. Helen Duncan's 1944 conviction under the British Witchcraft Act of 1735, the CIA Stargate programme (1972–1995, later about 12 million pages declassified) and the academic marginalisation of psi research up to Cardeña 2018 are three more – we treat them in our article Mediumship and Power: Helen Duncan, CIA Stargate and Academic Marginalisation. The present article treats schooling as a fourth variant of the same institutional pattern.
This is not a conspiracy. It is a filtering through accumulated institutional decisions. Curricula are drafted by subject didacticians, schoolbook publishers and ministries of culture. These three instances orient themselves on the academic canon of their discipline. The academic canon since 1906 is such that the named subjects do not appear in it. The school reproduces this filtering with two generations of delay. This is exactly the path dependency that Foucault described as a "regime of truth" and Bourdieu as "symbolic reproduction" – in each case not through evil intent but through a self-reinforcing institutional logic.
For the question "Why does my daughter from the biology track know that Eccles received the Nobel Prize but not that he was a substance dualist?" there is therefore no short conspiratorial answer. But there is a longer structural one: because in 1909 at Harvard it was institutionally decided that academic psychology was to have no more to do with psychical research. Because in 1953 in GDR pedagogy and in 1965 in West German pedagogy dialectical materialism and scientific realism respectively removed the metaphysically interesting writings of those very Nobel laureates from the school canon. Because schoolbook publishers in the 2010s have no institutional incentive to bring those writings back. That is the answer. It is more sober than any conspiracy theory and in most cases more uncomfortable, because it does not point to individual culprits but to an entire architecture.
What remains
- The Prussian school is real. 1717 under Frederick William I, 1763 across the whole kingdom under Frederick II. It was for its time an exceptional achievement and supported Prussia's rise in the 18th and 19th centuries.
- The functions were multi-layered. Reading and writing officially, administrative and military fitness structurally, disciplining in the form, leading away from "superstition" as an Enlightenment self-understanding. All four layers are well documented in historical research.
- The form survived the Humboldt break. Class group, lesson clock, grading scale, curriculum as filter – that is the Prussian architecture. Humboldt's humanistic educational ideal sits on top of it like a second layer.
- The model has gone global. Via Horace Mann in 1843 to the United States, via Meiji-Japan in 1872 into East Asia, from there into the rest of the world. Whoever today says "school" essentially means "Prussian elementary school with local adaptations".
- The filtering still operates. Curricula reproduce the academic canon with two generations of delay. What academic science has removed from its canon since 1906 – the subject of consciousness in its serious form, connected to top-level physics and psychology – is correspondingly not to be found in today's German curricula. That is not a conspiracy, it is path dependency. Curriculum filtering is only one of several parallel mechanisms – state power, secrecy and academic marginalisation are three more; see Mediumship and Power.
