Geographic Thought I: Greek, Roman, Arab, Chinese and Indian Scholars; Varenius, Kant, Humboldt, Ritter, Schaefer and Hartshorne; and the Impact of Darwinian Theory
2. Arab, Chinese and Indian scholars
While Europe's learning stagnated in the early Middle Ages, Arab scholars preserved and extended the Greek legacy, driven by trade, pilgrimage and administration. Al-Khwarizmi revised Ptolemy's coordinates in Kitab Surat al-Ard (9th century). Al-Masudi (10th century), the "Herodotus of the Arabs", travelled widely and wrote Meadows of Gold. Al-Biruni (973–1048) measured the Earth's radius by an ingenious method using the dip of the horizon from a mountain and wrote Kitab al-Hind (about 1030), a study of Indian society, science and geography. Al-Idrisi made the world map known as the Tabula Rogeriana (1154) for King Roger II of Sicily. Ibn Battuta travelled some 120,000 km across Africa and Asia, including India, and recorded it in his Rihla. Ibn Khaldun's Muqaddimah (1377) related the character of societies to their environment and set out a cyclical theory of the rise and fall of dynasties built on group solidarity (asabiyya).
Chinese geography began with the Yu Gong ("Tribute of Yu"), a chapter of the Shujing that describes nine provinces with their soils, products and tribute — among the earliest regional geographies. Pei Xiu (3rd century CE) set out six principles of cartography: graduated divisions (scale), a rectangular grid, pacing out the sides of triangles, measuring high and low, measuring right and acute angles, and measuring curves and straight lines. Zhang Heng built a seismoscope in 132 CE; the Buddhist pilgrims Faxian and Xuanzang (7th century) left detailed accounts of India; Shen Kuo (11th century) described magnetic declination and the formation of landforms by erosion and deposition; and Zheng He led seven great voyages across the Indian Ocean between 1405 and 1433. Indian scholarship combined Puranic cosmography — Jambudvipa and the seven concentric continents, with Bharatavarsha at the centre — with exact astronomy. Aryabhata (Aryabhatiya, 499 CE) taught that the Earth rotates on its axis and explained eclipses correctly; Varahamihira's Brihat Samhita (6th century) discussed weather, rainfall forecasting and the finding of groundwater; and Kautilya's Arthashastra describes land classification and the measurement of rainfall with a gauge.
3. Varenius, Kant, Humboldt, Ritter, Schaefer and Hartshorne
Bernhardus Varenius (1622–1650), in Geographia Generalis (1650), drew the first explicit distinction in modern geography, between general (systematic) geography, which studies the Earth as a whole and states laws, and special (regional) geography, which describes particular countries. General geography he divided into absolute (the Earth itself), relative (its relations to the heavens) and comparative parts; Newton edited the book for his Cambridge students. Immanuel Kant lectured on physical geography at Königsberg for four decades (1756–1796), and his classification of knowledge gave geography its philosophical place: sciences can be classified logically, by the things they study, or physically, by time and space — history describes things that follow one another in time (it is chronological) and geography things that lie beside one another in space (it is chorological).
Alexander von Humboldt (1769–1859) and Carl Ritter (1779–1859) founded modern geography, and both died in 1859. Humboldt, a naturalist and explorer, travelled through Spanish America with Aimé Bonpland (1799–1804), climbed Chimborazo, drew the first isotherms (1817), showed the altitudinal zonation of vegetation and summed up his vision of the unity of nature in Kosmos (five volumes, 1845–62). His method was empirical, systematic and inductive — the ancestor of systematic physical geography. Ritter, a professor at Berlin, wrote the vast Die Erdkunde (19 volumes, 1817–59). His geography was regional, comparative, anthropocentric and teleological: the Earth was designed by God as the home of humanity, and each region was a whole to be understood in relation to its people. Humboldt is the father of systematic geography, Ritter of regional geography.
Kant's chorological idea was revived by Alfred Hettner and brought to the English-speaking world by Richard Hartshorne in The Nature of Geography (1939): geography is the study of areal differentiation, the variable character of the Earth's surface; it integrates phenomena in particular places and is essentially idiographic, concerned with the unique rather than with general laws. In 1953 Fred K. Schaefer (the syllabus spells him "Scheafer") published "Exceptionalism in Geography: A Methodological Examination" in the Annals of the Association of American Geographers. He attacked the Kant–Hettner–Hartshorne position as "exceptionalism" — the claim that geography is a unique discipline exempt from the scientific search for laws — and argued that geography should be a nomothetic, law-seeking science of spatial arrangements. Schaefer died before the paper appeared; Hartshorne replied in 1955 and in Perspective on the Nature of Geography (1959). The exchange opened the way for the quantitative revolution and spatial science of the late 1950s and 1960s.
4. The impact of Darwinian theory on geographical thought
Charles Darwin's On the Origin of Species (1859) — published in the year Humboldt and Ritter died — reshaped geography in four ways. It replaced Ritter's teleology with a naturalistic account of change; it supplied the idea of evolution through stages, visible in Davis's geographical cycle of youth, maturity and old age; it encouraged an ecological view of organisms, including people, adjusting to their environment; and, through the idea of a struggle for existence, it fed social Darwinism. The most direct result was environmental determinism, often mixed with the neo-Lamarckian belief that characteristics acquired in response to the environment are inherited. Friedrich Ratzel (Anthropogeographie, 1882–91) treated the state as an organism needing Lebensraum (living space); his American follower Ellen Churchill Semple (Influences of Geographic Environment, 1911) opened with "Man is a product of the earth's surface"; and Ellsworth Huntington (Civilization and Climate, 1915) tied civilisation to a stimulating climate.
| School | Key figures | Position |
|---|---|---|
| Environmental determinism | Ratzel, Semple, Huntington | The natural environment controls human activity and culture |
| Possibilism | Paul Vidal de la Blache (genre de vie), Jean Brunhes; the term coined by Lucien Febvre | "There are no necessities, but everywhere possibilities" (Febvre, 1922): people choose among the options nature offers |
| Neo-determinism (stop-and-go determinism) | Griffith Taylor | Like traffic lights, nature sets the pace and direction of development; people can speed up, slow down or stop but cannot change the direction |
| Probabilism | O.H.K. Spate | The environment makes some responses more probable than others, without determining them |
Key takeaways
- Greeks: Anaximander's map, Herodotus's descriptions, Aristotle's spherical Earth and zones, Eratosthenes's name and circumference, Hipparchus's grid, Strabo's regional Geographica and Ptolemy's mathematical Guide to Geography.

- Varenius (1650): general versus special geography; Kant: geography is chorological as history is chronological; Humboldt (Kosmos, isotherms) founded systematic and Ritter (Die Erdkunde, teleological) regional geography — both died in 1859.
- Hartshorne (1939): areal differentiation, idiographic; Schaefer (1953, the document's "Scheafer"): exceptionalism attacked, geography as a nomothetic science of spatial arrangement — the prelude to the quantitative revolution.
- Darwin (1859) brought evolution, ecology and social Darwinism into geography; determinism (Ratzel, Semple, Huntington), possibilism (Vidal, Febvre), neo-determinism (Griffith Taylor) and probabilism (Spate) followed.

Show answer
Answer: A — Eratosthenes
Eratosthenes, librarian at Alexandria in the third century BCE, coined "geographia" and used the difference in the noon Sun's angle between Syene and Alexandria to obtain a strikingly good estimate of the Earth's circumference.Ptolemy's Geographike Hyphegesis is most important in the history of geography for:
Show answer
Answer: B — Coordinates of thousands of places and methods of map projection
Ptolemy's Guide to Geography (c. 150 CE) listed about 8,000 places by latitude and longitude and explained projections — the summit of mathematical geography. The 17-book regional account is Strabo's, and the dynastic cycle is Ibn Khaldun's.Kitab al-Hind, a detailed study of Indian society, science and geography written around 1030, is the work of:

Ibn Battuta wrote the Rihla, al-Idrisi made the Tabula Rogeriana and al-Masudi wrote Meadows of Gold.The Muqaddimah (1377), which related the character of societies to their environment and proposed a cyclical theory of dynasties based on group solidarity, was written by:
Show answer
Answer: A — Ibn Khaldun
Ibn Khaldun's Muqaddimah (the introduction to his universal history) developed the concept of asabiyya and linked climate and way of life to social character. Al-Khwarizmi revised Ptolemy, and Yaqut compiled a geographical dictionary.The "six principles of cartography", including graduated divisions for scale and a rectangular grid, were set out in the third century CE by the Chinese scholar:
Show answer
Answer: C — Pei Xiu
Pei Xiu's six principles made Chinese mapping systematic centuries before comparable European rules. Zhang Heng built a seismoscope, Shen Kuo described magnetic declination, and Zheng He led the Ming voyages.Bernhardus Varenius, in Geographia Generalis (1650), divided geography into:
Show answer
Answer: C — General (systematic) and special (regional) geography
Varenius distinguished general geography, which states laws about the Earth as a whole, from special geography, which describes particular regions — the first form of the systematic–regional dualism. The chronological–chorological contrast is Kant's.Immanuel Kant held that geography differs from history in that geography is:
Show answer
Answer: D — Chorological — it describes things that exist side by side in space
Kant classified sciences physically by time and space: history is chronological, geography chorological. The teleological view is Ritter's, and the nomothetic claim is Schaefer's.Which of the following are contributions of Alexander von Humboldt? Select all that apply.
Show answer
Answer: A — Kosmos, a multi-volume account of the unity of nature; B — The first map of isotherms
Humboldt wrote Kosmos (1845–62) and drew the first isotherms (1817). Die Erdkunde and the teleological, God-designed Earth belong to Carl Ritter, his contemporary at Berlin.Fred K. Schaefer's paper "Exceptionalism in Geography" (1953), whose author the syllabus spells "Scheafer", argued that:
Show answer
Answer: B — Geography should be a law-seeking science of spatial arrangements, not an exceptional idiographic discipline
Schaefer attacked the Kant–Hettner–Hartshorne "exceptionalism" and called for nomothetic geography; areal differentiation is Hartshorne's definition, which Schaefer criticised. The debate prepared the quantitative revolution.Assertion (A): Alexander von Humboldt and Carl Ritter both died in 1859. Reason (R): 1859 is also the year in which Darwin's On the Origin of Species was published. Choose the correct option.
Show answer
Answer: B — Both A and R are true, but R is not the correct explanation of A
Both statements are true, and the coincidence is often used to mark the end of the classical period of modern geography and the beginning of Darwinian influence — but one fact does not explain the other."There are no necessities, but everywhere possibilities" is the classic statement of possibilism by:
Show answer
Answer: A — Lucien Febvre
Febvre, the historian of the Annales school, coined "possibilism" for the ideas of Vidal de la Blache in A Geographical Introduction to History (1922). Semple and Huntington were determinists, and Griffith Taylor proposed stop-and-go determinism.Griffith Taylor's "stop-and-go determinism" compares the role of nature in human development to:
Show answer
Answer: B — Traffic lights, which set the direction while people control the pace
Taylor's neo-determinism likened nature to a traffic controller: people may go faster, slower or stop, but the broad direction is set by the environment. A menu of choices is possibilism; the organism needing Lebensraum is Ratzel's state.
