Some classical Western views about China
• Jonas Hanway: “the most effeminate people on
earth.”
• Goethe and Lord Shaftesbury: Greek and Roman
empires had more to teach than ancient China.
• The hero in Defoe’s The Further Adventures of
Robinson Crusoe (1719): “contemptible herd or
crowd of ignorant and sordid slaves, subjected to a
government qualified only to rule such people.”

Some Chinese Firsts in the World
• First treatise on trigonometry (221 B.C.)
• Publication of the first news paper, the so-called Beijing
Gazette in the reign of Tang (618-907) emperor Ming
Huang.
• Oldest mechanism for astronomical studies providing
continuous rotation (~8th century).

• Gunpowder, already being used in firecrackers, was first
tried out in warfare in 1161. The Mongols learned from
the Chinese and used it against Hungarians in 1241.
• Using calculating rods to solve equations with several
unknown quantities (~13th century).

Western Zhou (11th to 8th century B.C.)
According to the Records of Etiquette of the Zhou dynasty, there existed a
system consisting of five departments to control the production of
handicrafts in state organizations. [Juran 1990]

~Qin and Han (200B.C. to 300A.D.)
• Invention of the wheelbarrow.
• The central plain and parts of Szechuan:
continuously cultivated.
• Skilled husbandry: use of manure, distinctions
between different types of soils, attention to the
date of ploughing and sowing, drying out of
marshy regions, drainage of salty terrains. Several
recorded hydraulic engineers.

• First great increase in population.
• First census known to history in 2 A.D.: 57,671,400
taxable individuals.
• Lack of copper and tin caused a shift to cast iron.
• Cast iron axes, spades, knives, swords,…
• Cast iron is more breakable and takes on a sharper edge
than bronze.
• Forging of steel.
• China had a lead of several centuries over the West in
terms of iron and steel technologies.

B.C.
• Mass production using the same cast iron mold.
Molds with up to 3 identical cavities.

factory system that appeared in Europe only at the
beginning of the industrial revolution. Some
workshops had thousands of workers.

• Carts redesigned. 1 shaft to 2 shafts. Neck yoke to
breast yoke. Thus one horse could replace 2 to 4
horses.
• Measures of length and capacity, and gage of
cartwheels unified (standardization).
• First ever fixing of spokes at a slight outward angle.
• New class of merchant entrepreneurs (private
enterprise) using fleets of riverboats and large number
of carts. Economy grew beyond palace economy.
• Trade with Manchuria, northern India, etc. The silks

• Ceramics: Kilns all over.

Szechwan for paper; Hangzhou for printed books, …
• Gradual development of printing. Paper had become an
ordinary material by the end of Han age. “Use of stelae
bearing texts or drawings as stamps of blocks (with a coat
of damp paper, drying, inking, and reproduction on paper
with the help of a pad) [Gernet 1982, p. 333]” enabled
cheap and faithful reproductions.Seals made possible

Qing period (1644-1911)
• Manchu, “The enlightened despots.”
• The most extensive empire in the world.
• High watermark of agricultural techniques. Much
superior to agriculture in Europe. New crops:
sweet potato, the ground nut, sorghum, vegetables,
fruit (apart from the traditional wheat, barley,
millet, and rice). Fish farming. Industrial crops
(cotton, tea, sugar cane) too.
• China’s population growth outpaced that of
Europe.
S&T in Ancient China,

Qing continued (2)
• Craftsmanship on an ‘industrial’ scale.
• 200,000 textile industry workers in to the southwest of Shanghai alone.
• Tea production rose from 2.6 million pounds in
1762 to 23.3 million by the end of 18th century.
Supply to East India Co. from Guangzhou area.
• Export of porcelain objects to the world.
• Criticism of absolutism. The return of the

Einstein argued
Perhaps we should try to think why
something as unlikely and odd as
science has ever occurred anywhere
ever, rather than why something as
seemingly obvious (to us moderns) as
science didn’t occur elsewhere.
S&T in Ancient China,
KV Patri
46
Why China missed out on domestic
industrial revolution
Basically cultural reasons:
• Ideological orthodoxy.
• Stress on conformity and tradition.
• Interest in status quo of the dominant and
educated classes.
• Suppression of scientific invention by force
(as during the Inquisition in the West.)
S&T in Ancient China,
KV Patri
47
• Keeping the study of astronomy, botany,
engineering, and mathematics out of the
schools.
• The ‘tyranny of language’: ideographs do
not lend themselves to abstract
“theoretical” thinking.
• Lack of encouragement to develop laborsaving technologies owing to tremendous
pre-industrial population growth.
S&T in Ancient China,
KV Patri
48
Needham’s Thesis
[http://www.ucl.ac.uk/sts/gregory/325/handouts/h08_chi.doc]
• “The main reasons are to do with the nature of Chinese society,
in particular the stultifying nature of the Chinese feudal
bureaucracy in contrast to the rising capitalist democracies of
the West, and the narrow and secretive master/ apprentice
relations in all areas of Chinese learning.”
• ”The notion of physical law is clearly important. It may be that
the West derived this notion from Christian theology (the lawgiving God) which is absent in China, or that it came via Greek
notions in geometry applied to the world in the Renaissance
(Galileo; ‘The book of nature is written in the language of
geometry’). Chinese mathematics was more arithmetic than
geometrical.”
S&T in Ancient China,
KV Patri
49
Needham thesis 2
• “Within the Western tradition, it is easier to distinguish between
moral and physical law; this is not so in Chinese cosmology,
where everything has a place where it ought to be (but might not
be). In the West there has been a tradition of analytical and
causal thinking. We attempt to isolate those elements we believe
important, and then think in a scheme of cause and effect. The
mechanical world view is very conducive to this sort of thought,
as is the related motion of reductive explanation. However, the
Chinese tradition is one of thinking in terms of organic wholes
where each part is interrelated with each other and each part has
a place within the whole. Correlative and sympathetic modes of
thought, where the key notions are of principles and associations
linked sympathetically rather than causally are the central ideas
in this view.
