The Enlightenment 1550-1750 Flashcards
Empirical thought
- Observing, collecting data
- Allowed for Inductive Reasoning- conclusion based on evidence
Francis Bacon, ‘Proficience and Advancement of Learning’
1605:
- Empirical knowledge, learnt from experience and observation, is the most superior form of knowledge
- Use inductive reasoning by making a conclusion based on your evidence.
- Formed the foundation of future scientific thinking
What did Aristotle believe about the Solar system?
Earth was in centre, everything went round Sun.
- Copernicus, ‘On The Revolution of Heavenly Spheres’
2. What have historians argued was his impact?
- 1543
- Proposed universe was heliocentric, agreed w/Aristotle that planets moved in perfect circles - Some historians would say he led to other scientific theories; not v. influential, only 10 ppl heavily influenced- Church v. strong
Johannes Keplar, ‘Astronomia Nova’
1609:
I. Planet move in elliptical orbits (move in an oval shape) around the sun
II. Planets don’t travel at a constant speed, they speed up when approaching the sun
- Not v. influential, criticised by Church
Galileo, ‘Dialogue Concerning Two Chief World Systems’
1632:
- Revolutionary- explained how traditional Ptolemaic view of solar system was impossible and Copernican view was correct
- Can’t prove it mathematically, can’t explain eg how Earth moves
- Developed a system that fused maths and natural science
Why was ‘Dialogue Concerning Two Chief World Systems’ influential?
- Galileo blacklisted from Church
- Published in many different languages, v. influential
Isaac Newton, ‘Principia Mathematica
1687:
- Mathematically proved Kepler’s law of planetary motion.
- Proved centrifugal force, (planets are pulled towards the gravity of the sun, this also forms a circular orbit of planets around the sun)
What was ‘Mechanical Philosophy’?
Pubd by v. religious Rene Descartes in 1630s- ‘The world was a pure mechanism and was governed w/o influence of God’; everything serves purpose
Why was ‘Mechanical Philosophy’ influential in the decline of witchcraft?
Since Universe is composed of these mechanisms, can’t be influenced by God- designed it, but his influence can’t change it so Devil also doesn’t exist- thus witchcraft can’t be real. Influenced Newton
- ‘De Corpore’ by Thomas Hobbes promotes deductive reasoning over inductive reasoning. What is deductive reasoning and what is inductive reasoning?
- Hobbes’ Criticisms of Inductive Reasoning
1655:
1. - Deductive reasoning: an idea is tested to see if it’s true through observation
- Inductive reasoning: an idea is formed and then worked backward towards generalizations and theories.
2. Too experimental, never provides secure, irrefutable knowledge, and there is always an element of doubt w/it when some observable facts can’t be explained
What other theory did Hobbes come up with?
Materialism- Everything is created by matter, all observed events are result of matter; as we can see + touch everything, spirits can’t exist.
What did John Locke write and when?
‘Essay Concerning Human Understanding’ (1690)
- Humans born w/o knowledge- it only comes from experience so it can’t be fully accurate as experience differs
- All objects have primary and secondary characteristics- primary are objective, unchangeable but secondary eg colour, smell, taste, are based off individual perception so they are irrelevant
Why was John Locke’s work influential in the decline of magic?
- Spirits have no primary qualities so their existence can’t be proved empirically and scientifically
- Made no allowances for the supernatural as he was materialist
What was Gresham College?
- Members of collective shared interest in experimental investigation
- Opened after long effort to establish a permanent group studying mathematical science
- Impact was limited to academic circles but many involved go to Oxbridge, set up Royal Society
