Jean-Jacques Rousseau

Jean-Jacques Rousseau is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jean-Jacques Rousseau rather than just read about it. In short: Jean-Jacques Rousseau (UK: , US: ; French: [ʒɑ̃ʒak ʁuso]; 28 June 1712 – 2 July 1778) was a Genevan philosopher, philosophe, writer, and composer. His political philosophy influenced the progress of the Age of Enlightenment throughout Europe, as well as aspects of the French Revolution and the development of modern political, economic, and educational thought.

Key takeaways

  • Jean-Jacques Rousseau belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Jean-Jacques Rousseau to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Jean-Jacques Rousseau from memory before moving on to harder problems.

Reference excerpt

Jean-Jacques Rousseau (UK: , US: ; French: [ʒɑ̃ʒak ʁuso]; 28 June 1712 – 2 July 1778) was a Genevan philosopher, philosophe, writer, and composer. His political philosophy influenced the progress of the Age of Enlightenment throughout Europe, as well as aspects of the French Revolution and the development of modern political, economic, and educational thought. Rousseau's Discourse on Inequality, which argues that private property is the source of inequality, and The Social Contract, which outlines the basis for a legitimate political order, are cornerstones in modern political and social thought. Rousseau's sentimental novel Julie, or the New Heloise (1761) was important to the development of preromanticism and romanticism in fiction. His Émile, or On Education (1762) is an educational treatise on the place of the individual in society. Rousseau's autobiographical writings—the posthumously published Confessions (completed in 1770), which initiated the modern autobiography, and the unfinished Reveries of the Solitary Walker (composed 1776–1778)—exemplified the late 18th-century "Age of Sensibility", and featured an increased focus on subjectivity and introspection that later characterized modern writing.

Biography

Youth Rousseau was born in the Republic of Geneva, which was at the time a city-state and a Protestant associate of the Swiss Confederacy, now a canton of Switzerland. Since 1536, Geneva had been a Huguenot republic and the seat of Calvinism. Five generations before Rousseau, his ancestor Didier, a bookseller who may have published Protestant tracts, had escaped persecution from French Catholics by fleeing to Geneva in 1549, where he became a wine merchant.

Rousseau was proud that his family, of the moyen order (or middle-class), had voting rights in the city. Throughout his life, he generally signed his books "Jean-Jacques Rousseau, Citizen of Geneva". Geneva, in theory, was governed democratically by its male voting citizens. The citizens were a minority of the population when compared to the immigrants (inhabitants) and their descendants (natives). In fact, rather than being run by vote of the citizens, the city was ruled by a small number of wealthy families that made up the Council of Two Hundred; they delegated their power to a 25-member executive group from among them called the "Small Council". There was much political debate within Geneva, extending down to the tradespeople. Much discussion was held over the idea of the sovereignty of the people, of which the ruling class oligarchy was making a mockery. In 1707, democratic reformer Pierre Fatio protested this situation, saying "A sovereign that never performs an act of sovereignty is an imaginary being". He was shot by order of the Small Council. Jean-Jacques Rousseau's father, Isaac, was not in the city then, but Jean-Jacques's grandfather supported Fatio and was penalized for it. Rousseau's father, Isaac Rousseau, followed his grandfather, father, and brothers into the watchmaking business. He also taught dance for a brief period. Isaac, notwithstanding his artisan status, was well-educated and a lover of music. Rousseau wrote that "A Genevan watchmaker is a man who can be introduced anywhere; a Parisian watchmaker is only fit to talk about watches". In 1699, Isaac ran into political difficulty by entering a quarrel with visiting English officers, who in response drew their swords and threatened him. After local officials stepped in, it was Isaac who was punished, as Geneva was concerned with maintaining its ties to foreign powers. Rousseau's mother, Suzanne Bernard Rousseau, was from an upper-class family. She was raised by her uncle Samuel Bernard, a Calvinist preacher. He cared for Suzanne after her father, Jacques, who had run into trouble with the legal and religious authorities for fornication and having a mistress, died in his early 30s. In 1695, Suzanne had to answer charges that she had attended a street theatre disguised as a peasant woman so she could gaze upon M. Vincent Sarrasin, whom she fancied despite his continuing marriage. After a hearing, she was ordered by the Genevan Consistory to never interact with him again. She married Rousseau's father at the age of 31. Isaac's sister had married Suzanne's brother eight years earlier, after she had become pregnant and they had been chastised by the Consistory. The child died at birth. The young Rousseau was told a fabricated story about the situation in which young love had been denied by a disapproving patriarch but later prevailed, resulting in two marriages uniting the families on the same day. Rousseau never learnt the truth. Rousseau was born on 28 June 1712, and he later related: "I was born almost dying, they had little hope of saving me". He was baptized on 4 July 1712, in the great cathedral. His mother died of puerperal fever nine days after his birth, which he later described as "the first of my misfortunes". He and his older brother François were brought up by their father and a paternal aunt, also named Suzanne. When Rousseau was five, his father sold the house the family had received from his mother's relatives. While the idea was that his sons would inherit the principal when grown up and he would live off the interest in the meantime, in the end, the father took most of the substantial proceeds. With the selling of the house, the Rousseau family moved out of the upper-class neighbourhood and into an apartment house in a neighbourhood of craftsmen—silversmiths, engravers, and other watchmakers. Growing up around craftsmen, Rousseau would later contrast them favourably to those who produced more aesthetic works, writing "those important persons who are called artists rather than artisans, work solely for the idle and rich, and put an arbitrary price on their baubles". Rousseau was also exposed to class politics in this environment, as the artisans often agitated in a campaign of resistance against the privileged class running Geneva. Rousseau had no recollection of learning to read, but he remembered how when he was five or six his father encouraged his love of reading:

Worked examples

Example 1 — a first encounter with Jean-Jacques Rousseau

Start with the simplest possible case. Write down what Jean-Jacques Rousseau claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jean-Jacques Rousseau before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jean-Jacques Rousseau ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jean-Jacques Rousseau

In research
Jean-Jacques Rousseau appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Jean-Jacques Rousseau in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Jean-Jacques Rousseau is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1712 births, 1778 deaths, 18th-century Protestants, so understanding it makes those chapters shorter.
In everyday life
Look for Jean-Jacques Rousseau outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
