Marie Jean Antoine Nicolas de Caritat, marquis de Condorcet ([maʁi ʒɑ̃n‿ɑ̃twan nikola də kaʁita kɔ̃dɔʁˈse]; 17 September 1743 – 28 March 1794), known as Nicolas de Condorcet, was a French philosopher, mathematician, and early political scientist whose Condorcet method in voting tally selects the candidate who would beat each of the other candidates in a run-off election. Unlike many of his contemporaries, he advocated a liberal economy, free and equal public education, constitutionalism, and equal rights for women and people of all races. His ideas and writings were said to embody the ideals of the Age of Enlightenment and rationalism, and remain influential to this day. He died a mysterious death in prison after a period of being a fugitive from French Revolutionary authorities.
Condorcet was born in Ribemont, Aisne, and 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 raised by his devoutly religious mother. He was educated at the Jesuit College in Reims and at the Collège de Navarre in Paris, where he quickly showed his intellectual ability, and gained his first public distinctions in mathematics. When he was sixteen, his analytical abilities gained the praise of Jean le Rond d'Alembert and Alexis Clairaut; soon, Condorcet would study under d'Alembert.
A Condorcet method is any election method that elects the candidate that would win by majority rule in all pairings against the other candidates, whenever one of the candidates has that property. A candidate with that property is called a Condorcet winner (named for the 18th-century French mathematician and philosopher Marie Jean Antoine Nicolas Caritat, the Marquis de Condorcet, who championed such outcomes). A Condorcet winner doesn't always exist because majority preferences can be like rock/paper/scissors: for each candidate, there can be another that is preferred by some majority (this is known as Condorcet paradox).
Voting methods that always elect the Condorcet winner (when one exists) are the ones that satisfy the Condorcet criterion.
Most Condorcet methods have a single round of voting, in which each voter ranks the candidates from top to bottom. A voter's ranking is often called his/her order of preference, although it may not match his/her sincere order of preference since voters are free to rank in any order they choose and may have strategic reasons to misrepresent preferences. There are many ways that the votes can be tallied to find a winner, and not all ways will elect the Condorcet winner whenever one exists. The methods that will—the Condorcet methods—can elect different winners when no candidate is a Condorcet winner. Thus the Condorcet methods can differ on which other criteria they satisfy.[citation needed]
The Condorcet candidate or Condorcet winner of an election is the candidate who, when compared with every other candidate, is preferred by more voters. Informally, the Condorcet winner is the person who would win a two-candidate election against each of the other candidates. A Condorcet winner will not always exist in a given set of votes, which is known as Condorcet's voting paradox. When voters identify candidates on a left-to-right axis and always prefer candidates closer to themselves, a Condorcet winner always exists.
A voting system satisfies the Condorcet criterion if it chooses the Condorcet winner when one exists. Any method conforming to the Condorcet criterion is known as a Condorcet method.
It is named after the 18th century mathematician and philosopher Marie Jean Antoine Nicolas Caritat, the Marquis de Condorcet.
The Condorcet criterion implies the majority criterion; that is, any system that satisfies the former will satisfy the latter. Because of this, Arrow's impossibility theorem shows that any method which satisfies the Condorcet criterion will not satisfy independence of irrelevant alternatives.

Plot: The third Highlander movie takes place at 1994, which means it's a prequel of the second film. After the death of his beloved wife Heather some centuries ago, Connor MacLeod left the highlands of Scotland and wandered around the world. Finally, he got to Japan, where he met the famous sorcerer Nakano, who was an Immortal too. Soon, they became friends, and Nakano taught Conor some tricks. But one day, an old enemy, Kane, came to Japan willing to find Nakano's cave and kill him. Although he succeeded, after cutting Nakano's head the mountain collapsed and Kane was trapped. Now, centuries after, an excavation reveals Nakano's cave...
