Introduction
- 10 centuries of history, end of the Classical period to end of the medieval period
- What happens to science in this long span of time?
- Greek natural philosophy, in techniques and ideas, decays, is transmitted across
cultures, it recovers and eventually transforms
- Recovering the classical world view, adapting it Feudalism and religion
Classical World View
- No religious explanations, exclusion of trades and labour, breaking down nature
into components (elements, atoms), the importance of numbers, observation,
classification and logic, theories of the elements, the causes, geocentric
astronomical theories
From Classical to Feudal Civilization
- Western Roman Empire falls, institutions and technologies, decentralized
economic and political system
- Large-scale technologies, long-range technologies
- Wealthy (plutocrats or barbarians), estate owning class, peasants
- Land and tools in exchange for rent, tax or service on crops
- Feudal demands on science, classical world view sufficed
- Production more widespread and closer to people
- Subsistence economy, increased technological innovation, labour shortages
- Feudal need for science given mode of production
Outside Europe
- Dark Ages, Greek natural philosophy in India, Persia, Central Asia and China,
economic and cultural success
- Trade networks, manufacturing industry for luxury items
o Manufacturing innovations (e.g. looms, printing) from China to West
- Science thrived in India, China and Persia, mathematics, astronomy and medicine
Religious Factors
- Islam, Christianity, Buddhism, Zoroastrianism and Hinduism
- Priesthood, fixed rituals, belief in the order of the universe, sacred books,
