What Was the Enlightenment?
A Basic Definition
More than great men thinking great things.
Where and how did the Enlightenment happen?
Created new ways of interacting with one another: Public Sphere
New discourses (ideas, theories, criticism, rumors, etc.) that challenged the existing political system (the Ancièn Regime).

A period that propogated new discourses (ideas, theories, criticism, rumors, etc.) that challenged the current political system.

17th-Century Science
Royal Academies
Republic of Letters
Isaac Newton (1687)
John Locke (1690)


- Academies and Republic of letters
- In the mid-17th century, royal courts began creating academies
- English Royal society (1660)
- France: Royal Academie of Sciences (1666)
- Berlin: Academy of Sciences (1700)
- These academies mixed with the courtly academics to share their findings and other stuff.
- Led to the Republic of Letters
- A group of people connecting through the post
- In the mid-17th century, royal courts began creating academies
- Under this new dynamic the genesis of enlightenment thought developed:
- Isaac Newton (1687) Mathematical Principals of Natural Philosophy resolved the problem of planetary movement with the idea of gravity
- A force made things fall and could not be interrupted.
- Proved you could calculate the actions of the world
- Took awhile to influence people by mid 18c, it had caught on.
- had few practical affects
- But people wanted to apply scientific thought to other areas.
- John Locke (1690) wrote Treatises on Government
- Argued that government ruled through a relationship between the inhabitants and the government
- That contract existed to protect individual property (land, money,)
- Property basis of political theory
- So those that created that agreement were those with property
- Supported a property limitation on voting
- Government of the propertied people.
- This comes right out of the Glorious Revolution theory.
- Isaac Newton (1687) Mathematical Principals of Natural Philosophy resolved the problem of planetary movement with the idea of gravity
The (High) Enlightenment: The Philosophes
Charles Louis de Montesquieu (1689-1755)
François-Marie Arouet (Voltaire) (1694-1778)
Denis Diderot (1713-1784)
Jean-Jacques Rousseau (1712-1778)




Enlightenment
- Took the principals and methods of the intellectuals of the Scientific Revolution and applied them to social issues
- Driven in reaction to the calamities of the Wars of Religion, and especially the 30 years war, these intellectuals posited that reason as opposed the unquestioned authorities of traditional wisdom (i.e., the Church, religion, the classics) should be the ultimate arbiter of information and understanding the world and society.
- Philosophes (literary people, professors, journalists, economists, political scientists, etc.), as they called themselves, took the new
- Montesquieu (1689-1755) apply sci rev to society
- Attempted to apply the scientific method to government to understand the natural laws of social and political relationships.
- Argued there were three different kinds of governments: republic, monarchy, and despotism
- Also argued that separating the judicial, executive, and legislative power (separation of powers) provided the greatest freedom and security for a state.
- Voltaire (1694-1778) anti-institutional (religious)
- From prosperous middle class family, studied law, playwright. (wrote plays, letters, essays, etc.)
- Critical of traditional religion
- Saw religious toleration as an ideal.
- Became a Champion for Deism
- Saw god as a great creator that created the universe and stepped away, not intervening in it.
- God was the Great watch maker
- Diderot (1713-1784) focused on collecting and categorizing information and disseminating it
- Was the editor of the Encyclopedia, a 28 volume compendium of knowledge.
- Discussed matters from government to religion, written by philosophes.
- Huge proponent in spreading ideas of enlightenment
- Sold to lawyers, doctors
- Jean-Jacques Rousseau (1712-1778) new radical theories on government extended Lockian idea
- Discussed the origins of political power, argued that peopled adopted laws and governors to protect private property, but had since been
- Wrote The Social Contract (1762) in which he argued that communities/societies had a contract with the government, which is how it came into being, thus the general will of the people placed the government in power, and if the government did not follow the general will, it could be replaced for breaking the social contract. Huge statement, considering most governments were monarchies that claimed a hereditary right to rule.
Enlightenment: Invention of Race
Montesquieu 
David Hume 
- Not only did the sugar and coffee that was often produced on the colonies by African Slaves, Enlightenment philosophes tried to understand the demographic desparity in new ways.
- Previously slavery was justified due the “barbarity” of the Africans (meant lack of knowledge of the true religion).
- Montesquieu explained differences in cultures based on climates—connected hot climates with greater sexual drive, fewer inhibitions.
- Some attached these to characteristics of civilizations
- David Hume best demonstrates this
- He wrote in 1752 (Political Discourses): “No people living between the tropics could ever yet attain any art or civility.”
- In another book (Of National Character [1753]) Hume attached skin color to the role of climate in dictating the character of civilizations:
- “I am apt to suspect the negroes and in general all the other species of men (for there are four or five different kinds) to be naturally inferior to whites. There never was a civilized nation of any other complexion than white, nor even any individual eminent either in action or speculation. No ingenious manufactures amongst them, no arts, no sciences…Such a uniform and constant difference could not happen, in so many countries and ages, if nature had not made an original distinction betwixt these breeds of men.”
- Hume was rooting his ideas in nature, applying the same study of natural laws to the differences in race.
Causes of Enlightenment? The Economy
- But why do we get enlightenment?
- Coffee & Sugar
- Growing Wealth
- Growing Cities
But Why?
- The increase in wealth had a direct impact on the Enlightenment in three ways. And once again remember this wealth originated from Atlantic slave economy, based primarily on sugar and coffee.
- First: the growing wealth contributed to a dramatic growth in cities
- as more and more opportunities were available.
- Some of these opportunities were in writing and publishing like never before because more people had the ability to buy these books, and new institutions like the coffee house developed that purchased books and newspapers for their customers to read.
- Second, with the rise in wealth
- The royal courts lost their monopoly on cultural production. Previously, public intellectuals primarily resided at the court and were funded by the court. For instance, Galileo was a court astronomer, who even became an astronomer at the Pope’s court.
- In the eighteenth century, new centers of patronage developed, and new centers of intellectual exchange developed.
- The salon hosted by elite female nobles liberated intellectual pursuits from the prying eye of the royal officials, and public intellectuals could find new patrons and notoriety in these institutions. The Mason Lodges had a similar outcome as the salon, but as an all-male atmosphere, and it developed later in the century.
- Academies, though older, grew in prominence and became new places for public intellectuals to gain fame.
- Third: the rise of coffee and the coffee house:
- coffee was grown by slave labor in the Caribbean, and it was sweetened with sugar grown by slave labor in the Caribbean.
- The coffeehouse became another place for the public to gather, drink something that did not get you drunk, read newspapers or other books that were available, and discuss the politics and the news of the day.
- The coffeehouse became a center where enlightenment ideas spread into society and a public sphere began to develop (the idea that the government should be dependent on the people. Another way to say this is that the people began to imagine themselves as the origins of sovereignty rather than divine right monarchy). It spread enlightenment ideas even broader than the salons, academies, and mason lodges.
- Moreover, Coffee also became a mainstay of the salon in France where elites gathered to discuss philosophy and politics (see The Enlightenment and the Public Sphere for more on this). C
- These three conditions had a dramatic impact in liberating intellectual production from the prying eyes of royal and religious censors.
- For instance, Jean-Jacques Rousseau was one of the first authors to make a living as a modern author in the mid-1700s
- Most authors received pensions from the crown, or an academy or some other noble patron that supported their writing.
- But by the middle of the century, Jean-Jacques Rousseau was able to support himself on his writings. He also had to do this because he seemed to make everyone angry and was forced to flee France, Geneva, and England multiple times under fear of arrest because of his writing.
- Most authors received pensions from the crown, or an academy or some other noble patron that supported their writing.
- For instance, Jean-Jacques Rousseau was one of the first authors to make a living as a modern author in the mid-1700s
