Condorcet
Marie Jean Antoine Nicolas de Caritat, Marquis of Condorcet (; 17 September 1743 – 29 March 1794), known as Nicolas de Condorcet, was a French philosopher and mathematician. His ideas, including support for a liberal economy, free and equal public instruction, constitutional government, and equal rights for women and people of all races, have been said to embody the ideals of the Age of Enlightenment, of which he has been called the "last witness," and Enlightenment rationalism. He died in prison after a period of hiding from the French Revolutionary authorities. Early years Condorcet was born in Ribemont (in present-day Aisne), descended from the ancient family of Caritat, who took their title from the town of Condorcet in Dauphiné, of which they were long-time residents. Fatherless at a young age, he was taken care of by his devoutly religious mother who dressed him as a girl till age eight. He was educated at the Jesuit College in Reims and at the ''Collège de Navarre'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condorcet Method
A Condorcet method (; ) is an election method that elects the candidate who wins a majority of the vote in every head-to-head election against each of the other candidates, that is, a candidate preferred by more voters than any others, whenever there is such a candidate. A candidate with this property, the ''pairwise champion'' or ''beats-all winner'', is formally called the ''Condorcet winner''. The head-to-head elections need not be done separately; a voter's choice within any given pair can be determined from the ranking. Some elections may not yield a Condorcet winner because voter preferences may be cyclic—that is, it is possible (but rare) that every candidate has an opponent that defeats them in a two-candidate contest.(This is similar to the game rock paper scissors, where each hand shape wins against one opponent and loses to another one). The possibility of such cyclic preferences is known as the Condorcet paradox. However, a smallest group of candidates that beat al ...

Condorcet Criterion
An electoral system satisfies the Condorcet winner criterion () if it always chooses the Condorcet winner when one exists. The candidate who wins a majority of the vote in every head-to-head election against each of the other candidatesthat is, a candidate preferred by more voters than any othersis the Condorcet winner, although Condorcet winners do not exist in all cases. It is sometimes simply referred to as the "Condorcet criterion", though it is very different from the "Condorcet loser criterion". Any voting method conforming to the Condorcet winner criterion is known as a Condorcet method. The Condorcet winner is the person who would win a two-candidate election against each of the other candidates in a plurality vote. For a set of candidates, the Condorcet winner is always the same regardless of the voting system in question, and can be discovered by using pairwise counting on voters' ranked preferences. A Condorcet winner will not always exist in a given set of votes, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sophie De Condorcet
Sophie de Condorcet (1764 in Meulan – 8 September 1822 in Paris), also known as Sophie de Grouchy and best known as Madame de Condorcet, was a prominent French salon hostess from 1789 to the Reign of Terror, and again from 1799 until her death in 1822. She was also a philosopher and the wife of the mathematician and philosopher Nicolas de Condorcet, who died during the Reign of Terror. Despite his death and the exile of her brother, Marshal Emmanuel de Grouchy, between 1815 and 1821, she maintained her own identity and was well-connected and influential before, during, and after the French Revolution. As a hostess, Madame de Condorcet was popular for her kind heart, beauty, and indifference to a person's class or social origins. Unlike that of her fellow- Girondist hostess Madame Roland, Madame de Condorcet's salon always included other women, notably Olympe de Gouges. Condorcet was also a writer and a translator, being highly educated for her day, and was fluent in English an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voting Paradox
The Condorcet paradox (also known as the voting paradox or the paradox of voting) in social choice theory is a situation noted by the Marquis de Condorcet in the late 18th century, in which collective preferences can be cyclic, even if the preferences of individual voters are not cyclic. This is paradoxical, because it means that majority wishes can be in conflict with each other: Suppose majorities prefer, for example, candidate A over B, B over C, and yet C over A. When this occurs, it is because the conflicting majorities are each made up of different groups of individuals. Thus an expectation that transitivity on the part of all individuals' preferences should result in transitivity of societal preferences is an example of a fallacy of composition. The paradox was independently discovered by Lewis Carroll and Edward J. Nanson, but its significance was not recognized until popularized by Duncan Black in the 1940s. Example Suppose we have three candidates, A, B, and C, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condorcet's Jury Theorem
Condorcet's jury theorem is a political science theorem about the relative probability of a given group of individuals arriving at a correct decision. The theorem was first expressed by the Marquis de Condorcet in his 1785 work ''Essay on the Application of Analysis to the Probability of Majority Decisions''. The assumptions of the theorem are that a group wishes to reach a decision by majority vote. One of the two outcomes of the vote is ''correct'', and each voter has an independent probability ''p'' of voting for the correct decision. The theorem asks how many voters we should include in the group. The result depends on whether ''p'' is greater than or less than 1/2: * If ''p'' is greater than 1/2 (each voter is more likely to vote correctly), then adding more voters increases the probability that the majority decision is correct. In the limit, the probability that the majority votes correctly approaches 1 as the number of voters increases. * On the other hand, if ''p'' is les ...

Sketch For A Historical Picture Of The Progress Of The Human Mind
''Sketch for a Historical Picture of the Progress of the Human Mind'' (french: Esquisse d'un tableau historique des progrès de l'esprit humain) is a work by the French philosopher and mathematician Marquis de Condorcet, written in 1794 while in hiding during the French Revolution and published posthumously in 1795. The first edition of An Essay on the Principle of Population (1798) by Thomas Malthus was largely written as a response to the work of William Godwin and Condorcet's ''Sketch'', as is evidenced by its full title: "An Essay on the Principle of Population, as it affects the Future Improvement of Society with remarks on the Speculations of Mr. Godwin, M. Condorcet, and Other Writers". Description Condorcet's ''Sketch for a Historical Picture of the Progress of the Human Spirit'' was perhaps the most influential formulation of the idea of progress Progress is the movement towards a refined, improved, or otherwise desired state.

Girondin Constitutional Project
The Girondin constitutional project, presented to the French National Convention on 15 and 16 February 1793 by Nicolas de Caritat, formerly the Marquis de Condorcet, is composed of three parts: * An ''Exposition of the Principles and Motives of the Constitutional Scheme'', approx. 80 pages * A ''Draft Declaration of the Natural, Civil, and Political Rights of Man'', in 33 articles * A ''Draft French Constitution'', in 13 titles The work was signed by the eight members of the Convention's Constitution Committee: Condorcet, Gensonné, Barrère, Barbaroux, Paine, Pétion, Vergniaud and Sieyès. Principles and motives In the exposition of the principles and motives behind the constitutional scheme that he reads before the National Convention, Condorcet begins, as a true mathematician, by a description of the "problem to solve": ''To give to a territory of twenty-seven thousand square leagues, inhabited by twenty-five million individuals, a constitution which, being founde ...

Girondin
The Girondins ( , ), or Girondists, were members of a loosely knit political faction during the French Revolution. From 1791 to 1793, the Girondins were active in the Legislative Assembly and the National Convention. Together with the Montagnards, they initially were part of the Jacobin movement. They campaigned for the end of the monarchy, but then resisted the spiraling momentum of the Revolution, which caused a conflict with the more radical Montagnards. They dominated the movement until their fall in the insurrection of 31 May – 2 June 1793, which resulted in the domination of the Montagnards and the purge and eventual mass execution of the Girondins. This event is considered to mark the beginning of the Reign of Terror. The Girondins were a group of loosely affiliated individuals rather than an organized political party and the name was at first informally applied because the most prominent exponents of their point of view were deputies to the Legislative Assembly from the ...

Legislative Assembly (France)
The Legislative Assembly (french: link=no, Assemblée législative) was the legislature of the Kingdom of France from 1 October 1791 to 20 September 1792 during the years of the French Revolution. It provided the focus of political debate and revolutionary law-making between the periods of the National Constituent Assembly and of the National Convention. History Background The National Constituent Assembly dissolved itself on 30 September 1791. Upon Maximilien Robespierre's motion, it had decreed that none of its members would be eligible to the next legislature. Its successor body, the Legislative Assembly, operating over the liberal French Constitution of 1791, lasted until 20 September 1792 when the National Convention was established after the insurrection of 10 August just the month before. The Legislative Assembly entrenched the perceived left–right political spectrum that is still commonly used today. There were 745 members. Elections The elections of 1791, ...

Idea Of Progress
Progress is the movement towards a refined, improved, or otherwise desired state. In the context of progressivism, it refers to the proposition that advancements in technology, science, and social organization have resulted, and by extension will continue to result, in an improved human condition; the latter may happen as a result of direct human action, as in social enterprise or through activism, or as a natural part of sociocultural evolution. The concept of progress was introduced in the early-19th-century social theories, especially social evolution as described by Auguste Comte and Herbert Spencer. It was present in the Enlightenment's philosophies of history. As a goal, social progress has been advocated by varying realms of political ideologies with different theories on how it is to be achieved. Measuring progress Specific indicators for measuring progress can range from economic data, technical innovations, change in the political or legal system, and questions ...

College Of Navarre
The College of Navarre (french: Collège de Navarre) was one of the colleges of the historic University of Paris, rivaling the Sorbonne and renowned for its library. History It was founded by Queen Joan I of Navarre in 1305, who provided for three departments, the arts with 20 students, philosophy with 30 and theology with 20 students. The queen bequeathed part of her fine ''hôtel de Navarre'' in rue Saint André des Arts, together with lands generated rents of 2000 ''livres'' p.a. in her counties of Champagne and Brie. Her trustees decided to sell the Paris property and acquire an ample plot on the Montagne Sainte-Geneviève (rue de la Montagne-Sainte-Geneviève / rue Descartes), right in the Latin Quarter, and build the college anew. The first stone, laid 12 April 1309, was for the college chapel. Provision was made also for the scholars' support, 4 Paris sous weekly for the artists, 6 for the logicians and 8 for the theologians. These allowances were to continue until the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
