Scientific Revolution and the Enlightenment Flashcards
The Scientific Revolution:
Term coined in 1939 – late idea
Revolution or process of change?
Thomas Kuhn = ‘Paradigm Shift’
Central to idea of a revolution was the Paradigm shift
Idea developed in 1960s
According to this view, most scientific work exists within a prevailing framework or a paradigm, ideas that prop up a scientific belief
Revolution or paradigm shift occurs when the results of scientific inquiry overthrow the paradigm itself resulting in a new paradigm
Paradigm of the humours over turned
Paradigm shift of the world overthrown in Early Modern Period
Science:
EMP called science the Natural Philosophy
Natural Philosophy = study of the natural world
‘Science’ – ‘scire’ (to know) – ‘Scientia’ (knowledge)
Science in EMP = knowledge
Not till 18th century is science identified, referred to as natural philosophy
Natural Philosophy in the late middle ages= religious study, means of understanding the glory of God in the meaning of nature
Aristotle and Ptolemy’s Universe:
Idea of universe holds for millennium
Aristotle: the philosopher, became foundation of many of the ideas held in the middle ages and beginning of EMP
Aristotle saw the Earth at the centre of the universe
Ptolemy in the second century corrected some of Aristotle’s ideas but this was the main view of the universe
Nicholas Copernicus:
Polish priest, astronomer
Mathematically Aristotle’s system didn’t work – needed a heliocentric universe whereby the sun is at the centre
Produced a book in 1543 – purely mathematical argument without proof, thus met with a lot of resistance both observational and religious
Challenged Aristotle and Ptolemy’s model of the universe
Copernicus argued mathematically argument of Aristotle and Ptolemy’s model was flawed in his book ‘on the Revelations of the Heavenly Bodies’
Mathematical hypothesis
The Copernican system – based on maths, still based on the Aristotle system, still concentric circles but changed positioning
The Copernican system
Based on maths, still based on the Aristotle system, still concentric circles but changed positioning
Brahe and Kepler:
Observed the universe and stated solar system was extinct, broadly made observations by eye
Brahe:
A Danish nobleman and astronomer
Observed celestial events such as the supernova in the 1570s – showed that the heavens changed, no fixed system of stars
Brahe – did not support heliocentric model but challenged Aristotle by stating stars changed
Kepler:
German astronomer
Developed Brahe’s observations
1609 proposed a heliocentric universe
Observations meant had to have elliptical orbits
Galileo:
Used the telescope
Convinced Copernicus correct – it was a heliocentric universe
Moon didn’t glow – reflected suns light
Other planets also had moons
Revolutionary ideas expressed in ‘The Starry Messenger’ in 1610
Changing idea that the universe is fixed and that the Earth is special and at the centre
Named moons of Jupiter to the Medici family as a tribute – funded his investigations
Prosecuted by the Catholic church due to his conclusions – attempting to say something about theology
Science and Religion:
Most scientists heavily religious – not a huge conflict between science and the church
Natural Philosophy stemmed from religion – science about religion
Mysticism essential to the scientific revolution
Epistemological Questions brought to the forefront by science
Scientism introduced by journeys to new worlds
Alchemists:
Turn (metal) lead into Gold
Half chemistry
Half mysticism
Central to the development of science
Alchemist – Paracelsus:
Used mystic arts to understand world around them
Rested on aim to get pure elements
Developed methods for scientific inquiries
Developed equipment such as the beaker and balance scales
The Scientific Method:
Ongoing process
Astronomy and Astrology not separate until around the 18th century
Bacon:
Followed system of induction
Took methods from alchemy and applied them to natural philosophy
English scholar, politician
Bacon rejected claims based on logic and reason alone
Needed to provide reason and explanation
Observe, generalised explanation, induction and then test that explanation and then may come to a conclusion –The Scientific Method
Believed strongly in ideas associated with alchemy e.g. astronomy and astrology were not separate categories until the 18th century – science not free from superstition
Bacon: The Scientific Method
Observe, generalised explanation, induction and then test that explanation and then may come to a conclusion
Rene Descartes:
Attempted to bring a new and certain foundation for knowledge
French mathematician
“I doubt therefore I think, I think therefore I am” – turns scepticism into a foundation for knowledge, even in doubt you find certainty you exist
Developed a system of deduction
2 basic substances: matter or body and mind or spirit – humans a union of these 2 substances but these substances remain separate
Cartesian Dualism:
Cartesians – rejected the Galenic view of the world, 4 humours, Descartes argues that the humours have little connection
Viewed God as the prime mover
Mind and Body are separate – no relationship between each humour
Sir Isaac Newton:
Used observation of the natural world to reinforce the belief in God
God = one not three
Unorthodox beliefs as part of the scientific revolution
Keens = Newton was the last of the magicians
Wrote extensively on Alchemy
Theory of gravity – reinforces the idea that the sun can still be the centre of the universe – brought together ideas of Kepler and Galileo
