Jean Buridan ( French: [byʁidɑ̃] ; Latin : Johannes Buridanus ; c. 1301 – c. 1359/62 ) was an influential 14th‑century French philosopher .
58-604: Buridan taught in the faculty of arts at the University of Paris for his entire career and focused in particular on logic and on the works of Aristotle . Buridan sowed the seeds of the Copernican Revolution in Europe. He developed the concept of impetus , the first step toward the modern concept of inertia and an important development in the history of medieval science . His name is most familiar through
116-409: A basin to store rainwater, which would then be slowly released into the sewer system, preventing overflow. Plans also call for several public swimming areas to be made available by 2025, ending a ban instituted in 1923 due to the polluted water. These efforts have produced mixed results, as E. coli levels have often been found to be far higher than what is safe to swim in, though this could depend on
174-409: A falling body could be understood in terms of its gradual accumulation of units of impetus. Because of his developments, historians of science Pierre Duhem and Anneliese Maier both saw Buridan as playing an important role in the demise of Aristotelian cosmology . Duhem even called Buridan the forerunner of Galileo . Zupko has disagreed, pointing out that Buridan did not use his theory to transform
232-491: A mixture of terminology, e.g., Harvard University has a Faculty of Arts and Sciences and a Law School . The medieval University of Bologna , which served as a model for most of the later medieval universities in Europe, had four faculties: students began at the Faculty of Arts, graduates from which could then continue at the higher Faculties of Theology , Law , and Medicine . The privilege to establish these four faculties
290-459: A population over 100,000 are in the Seine watershed: Le Havre at the estuary, Rouen in the Seine valley and Reims at the northern limit—with an annual urban growth rate of 0.2 percent. The population density is 201 per square kilometer. Tributaries of the Seine are, from source to mouth: Due to concentrated levels of industry, agriculture and urban populations of Paris and its surroundings,
348-481: A secular enterprise based on what is evident to both the senses and the intellect, rather than the non-evident truths of theology revealed through scripture and doctrine. The last appearance of Buridan in historical documents came in 1359, where he was mentioned as the adjudicator in a territorial dispute between the English and Picard nations. It is supposed that he died sometime after then, since one of his benefices
406-582: Is 98 km (61 mi) long and has 8 locks. At Charenton-le-Pont is the mouth of the Marne . Upstream from Paris seven locks ensure navigation to Saint Mammès , where the Loing mouth is situated. Through an eighth lock the river Yonne is reached at Montereau-Fault-Yonne. From the mouth of the Yonne, larger ships can continue upstream to Nogent-sur-Seine (48 km [30 mi], 7 locks). From there on,
464-588: Is a 777-kilometre-long (483 mi) river in northern France . Its drainage basin is in the Paris Basin (a geological relative lowland) covering most of northern France. It rises at Source-Seine , 30 kilometres (19 mi) northwest of Dijon in northeastern France in the Langres plateau, flowing through Paris and into the English Channel at Le Havre (and Honfleur on the left bank). It
522-637: Is a university faculty teaching philosophy , or in some cases, humanities in general. In the universities of continental Europe , the Faculty of Arts has more often been named the equivalent of " Faculty of Philosophy " (e.g., Norwegian : Det filosofiske fakultet , Slovene : Filozofska fakulteta ). Nowadays this is a common name for the faculties teaching humanities . Examples include: Faculty of Political Science examples include: Seine The Seine ( / s eɪ n , s ɛ n / sayn, sen , French: [sɛn] )
580-554: Is a university faculty teaching law, or a law school faculty. Examples include: A Faculty of Management Studies is a university division teaching management studies . Examples include: In English-speaking academia, Faculty of Music normally refers to a university department, especially at Oxford and Cambridge (UK). In the US, the use of 'faculty' often relates to academic and teaching staff. Examples include: Faculty of Natural Sciences examples include A Faculty of Philosophy
638-426: Is a university faculty that can teach a range of disciplines which can include nursing and midwifery , public health , health services management and sports science . Examples include: A Faculty of Humanities is a university faculty teaching humanities . Examples include: A Faculty of Information Technology is a university faculty teaching information technology . Examples include: A Faculty of Law

On 28 or 29 March 845, an army of Vikings led by a chieftain named Reginherus, which is possibly another name for Ragnar Lothbrok , sailed up the River Seine with siege towers and sacked Paris . On 25 November 885, another Viking expedition led by Rollo
754-490: Is navigable by ocean-going vessels as far as Rouen , 120 kilometres (75 mi) from the sea. Over 60 percent of its length, as far as Burgundy , is negotiable by large barges and most tour boats, and nearly its whole length is available for recreational boating; excursion boats offer sightseeing tours of the river banks in the capital city, Paris. There are 37 bridges in Paris across the Seine (the most famous of which are

François Villon , Ballade des dames du temps jadis , 9–16 Apocryphal stories abound about his reputed amorous affairs and adventures which are enough to show that he enjoyed a reputation as a glamorous and mysterious figure in Paris life. None of
870-472: Is unlikely that he could not afford to study theology, given that he received several bursaries and stipends. Indeed, he is listed in a document from 1350 as being among the teachers capable of supporting themselves without the need for financial assistance from the University. Zupko has speculated that Buridan "deliberately chose to remain among the 'artists [ artistae ]'," possibly envisioning philosophy as

A notable bridge, which is also the last along the course of the river, is the Pont de Normandie , the ninth longest cable-stayed bridge in the world, which links Le Havre and Honfleur . The Seine rises in the commune of Source-Seine , about 30 kilometres (19 mi) northwest of Dijon . The source has been owned by
986-491: The University of Vienna . Another story talks of him hitting Pope Clement VI with a shoe. The concept of inertia was alien to the physics of Aristotle . Aristotle, and his peripatetic followers held that a body was maintained in motion only by the action of a continuous external force . Thus, in the Aristotelian view, a projectile moving through the air would owe its continuing motion to eddies or vibrations in
1044-564: The thought experiment known as Buridan's ass , but the thought experiment does not appear in his extant writings. Buridan was born sometime before 1301, perhaps at or near the town of Béthune in Picardy , France , or perhaps elsewhere in the diocese of Arras. He received his education in Paris, first at the Collège du Cardinal Lemoine and then at the University of Paris , receiving his Master of Arts degree and formal license to teach at
1102-487: The 1800s, the river was much shallower within the city, and consisted of a small channel of continuous flow bordered by sandy banks (depicted in many illustrations of the period). Today the depth is tightly controlled and the entire width of the river between the built-up banks on either side is normally filled with water. The average flow of the river is very low, only a few cubic metres per second, but much higher flows are possible during periods of heavy runoff. Dredging in
1160-495: The 1960s marked an upturn in agricultural pollution due to land use changes that had previously scaled with population growth. Heavy industries near Paris and along the Oise River discharged virtually untreated wastewaters from the turn of the 19th century, causing concentrations of toxins in the river that were ignored until the late 1980s. Major French laws to address water quality were passed in 1898, 1964, 1996, and 2006. At
1218-704: The 1960s mostly eliminated tidal bores on the lower river, known in French as "le mascaret." Four large storage reservoirs have been built since 1950 on the Seine as well as its tributaries Yonne, Marne, and Aube. These help in maintaining a constant level for the river through the city, but cannot prevent significant increases in river level during periods of extreme runoff. The dams are Lac d’Orient , Lac des Settons , Lake Der-Chantecoq , and Auzon-Temple and Amance, respectively. A very severe period of high water in January 1910 resulted in extensive flooding throughout

The specific activity of these sewage bacteria is typically three to four times greater than that of the autochthonous (background) bacterial population. Heavy metal concentrations in the Seine are relatively high. The pH level of
1334-627: The Battle of Normandy. Some of the Algerian victims of the Paris massacre of 1961 drowned in the Seine after being thrown by French policemen from the Pont Saint-Michel and other locations in Paris. At the 1900 Summer Olympics , the river hosted the rowing , swimming , and water polo events. Twenty-four years later , it hosted the rowing events again at Bassin d'Argenteuil, along
1392-500: The Diocese of Arras and Master of Arts]." As university statutes permitted only those educated in theology to teach or write on the subject, there are no writings from Buridan on either theological matters or commentary of Peter Lombard 's Sentences . Speculation on his reasons for avoiding religious matters have remained uncertain. Most scholars think it is unlikely that he went unnoticed, given his philosophical talents. As well, it
1450-467: The Faculty of Arts, while the degree of Doctor Philosophiae (Doctor of Philosophy) derives its name from the Faculty of Philosophy, German name of the same faculty. Whether called Faculty of Arts or Faculty of Philosophy , it taught a range of subjects with general and fundamental applicability. The higher Faculty of Law and Faculty of Medicine were intended, much like today, for specialized education required for professions. The Faculty of Theology
1508-470: The French government sought to reduce bacterial levels in the river to those safe for swimming. During the Olympics, daily tests of the water quality were taken to determine if it was safe for swimming; this caused the triathlon to be delayed by a day, before being allowed to proceed on July 31. A few of the triathletes who swam in the river became sick afterwards, though it was not clear if the Seine water
1566-716: The Seine Maritime is followed by a canalized section ( Basse Seine ) with four large multiple locks until the mouth of the Oise at Conflans-Sainte-Honorine (170 km [110 mi]). Smaller locks at Bougival and at Suresnes lift the vessels to the level of the river in Paris, where the junction with the Canal Saint-Martin is located. The distance from the mouth of the Oise is 72 km (45 mi). The Haute Seine , from Paris to Montereau-Fault-Yonne ,
1624-405: The Seine at Pont Neuf has been measured to be 8.46. Despite this, the water quality has improved significantly over what several historians at various times in the past called an "open sewer". In 2018, a €1.4 billion ($ 1.55 billion) cleanup programme called the "Swimming Plan" was launched with the aim of making the river safe to use for the 2024 Summer Olympics . The project included constructing
1682-533: The Seine beside the Tuileries Garden . Having a length of sixty-six feet and an eight-foot beam Fulton's steamboat attained speeds of three to four miles per hour against the Seine's current. Reaching the Seine was one of the original objectives of Operation Overlord , during the Second World War , in 1944. The Allies' intention was to reach the Seine by 90 days after D-Day . That objective
1740-426: The Seine north of Paris. More than a century later, during the 2024 Summer Olympics , the Seine hosted a boat parade with boats for each national delegation during the opening ceremony . The river was also the site of the men's and women's event for marathon swimming , as well as the swimming portion of the triathlon . Although swimming in the Seine had been banned since 1923, a €1.4 billion cleanup effort by
1798-543: The Seine-Normandy watershed experiences the highest human impacts of any hydrographic basin in France. Compared to most other large European rivers, the ability of the Seine to dilute urban sewage and farmland runoff is very low. Low oxygen levels, high concentrations of ammonia, nitrites and faecal bacteria, extending from Paris to the estuary, have been issues for over a century. The advent of nitrogenous fertilizers in

1856-430: The Seine. By the early 2020s, the number of fish species near Paris had rebounded to 32. Periodically the sewage systems of Paris experience a failure known as sanitary sewer overflow , often in periods of high rainfall. Under these conditions, untreated residential and industrial sewage is discharged into the Seine to prevent backflow . This is due in large part to Paris' "single system" drainage scheme dating from
1914-415: The beginning of the 20th century, most domestic sewage was used as fertilizer for nearby croplands. As populations grew, the agricultural capacity to absorb those wastewaters was exceeded. Large-scale construction of waste water treatment plants (WWTPs) began in 1940 to meet demand; however, by 1970, about 60% of urban sewage was allowed to flow into the river untreated. The resulting oxygen depletion reduced
1972-410: The city of Paris since 1864. A number of closely associated small ditches or depressions provide the source waters, with an artificial grotto laid out to highlight and contain a deemed main source. The grotto includes a statue of a nymph, a dog, and a dragon. On the same site are the buried remains of a Gallo-Roman temple . Small statues of the dea Sequana "Seine goddess" and other ex-votos found at
2030-410: The city of Paris. The Seine again rose to threatening levels in 1924, 1955, 1982, 1999–2000, June 2016, and January 2018. After a first-level flood alert in 2003, about 100,000 works of art were moved out of Paris, the largest relocation of art since World War II . Much of the art in Paris is kept in underground storage rooms that would have been flooded. A 2002 report by the French government stated
2088-529: The commentary of John Philoponus on Aristoteilan physics. In this he was possibly influenced by John Philoponus who was developing the Stoic notion of hormé (impulse). The major difference between Buridan's theory and that of his predecessor is that he rejected the view that the impetus dissipated spontaneously, instead asserting that a body would be arrested by the forces of air resistance and gravity which might be opposing its impetus. Buridan further held that
2146-468: The earlier rainstorm during the opening ceremony had driven some untreated rainwater back into the Seine. However, the triathlon proceeded the following day, after testing found the water quality to be sufficient for swimming. The name Seine comes from Gaullish Sēquana , from the Celtic Gallo-Roman goddess of the river, as offerings for her were found at the source. Sometimes it

Examples include: A Faculty of Health
2262-407: The impetus of a body increased with the speed with which it was set in motion, and with its quantity of matter. This is closely related to the modern concept of momentum . Buridan saw impetus as causing the motion of the object: Buridan also contended that impetus is a variable quality whose force is determined by the speed and quantity of the matter in the subject. In this way, the acceleration of

Unusually, he spent his entire academic life in the faculty of arts, rather than obtaining the doctorate in law , medicine or theology that typically prepared the way for a career in philosophy . Also unusual for a philosopher of his time, Buridan further maintained his intellectual independence by remaining a secular cleric , rather than joining a religious order . A papal letter of 1330 refers to him as simply, " clericus Atrebatensis diocoesis, magister in artibus [a cleric from

Measures taken in the early 2000s due to the Water Framework Directive led to significant reductions of organic carbon, phosphorus and ammonium, which in turn decreased the occurrence and severity of phytoplankton blooms. Continued WWTP construction and new treatment methods improved environmental conditions. In 2009, it was announced that Atlantic salmon had returned to

The river is only 24 metres (79 ft) above sea level 446 kilometres (277 mi) from its mouth, making it slow flowing and thus easily navigable. The Seine Maritime, 123 kilometres (76 mi) from the English Channel at Le Havre to Rouen, is the only portion of the Seine used by ocean-going craft. The tidal section of

At Marcilly-sur-Seine the 19th century Canal de la Haute-Seine used to allow vessels to continue all the way to Troyes . This canal has been abandoned since 1957. The Seine's average depth in Paris today is approximately 9.5 meters (31 feet). Until locks were installed to raise the level in

He added that "We have to understand that climatic change is not a word, it's a reality." The basin area, including a part of Belgium, is 78,910 square kilometres (30,470 sq mi), 2 percent of which is forest and 78 percent cultivated land. In addition to Paris, three other cities with

To demonstrate the river's improved cleanliness, Mayor Anne Hidalgo and President Emmanuel Macron both pledged to take a swim in the waters, and Hidalgo did so on July 17, 2024. During the Summer Olympics, the date of the triathlon was postponed due to water quality issues, as

Some rumors hold that he died when the King of France had him put in a sack and thrown into the River Seine after his affair with the Queen came to light. François Villon alludes to this in his famous poem Ballade des Dames du Temps Jadis . Others suggest that he was expelled from Paris due to his nominalist teachings and moved to Vienna to found
2842-472: The surrounding medium, a phenomenon known as antiperistasis . In the absence of a proximate force, the body would come to rest almost immediately. The theory of impetus proposed that motion was maintained by some property of the body, imparted when it was set in motion. Buridan was the first to name this motion-maintaining property impetus but the theory itself probably did not originate with him. A less sophisticated notion of impressed forced can be found in
2900-566: The teaching bodies of medieval universities (the others being Law , Medicine and Theology ), the Faculty of Arts was the lowest in rank but also the largest (the higher faculties admitted only Arts graduates). Instead of "Arts", this faculty often had the name " Philosophy ". Nowadays this is still a common name for faculties teaching humanities (e.g.,) Norwegian : Det filosofiske fakultet , Slovene : Filozofska fakulteta ). A Faculty of Classics may be focused on ancient history, culture and ancient literature. The title may refer to
2958-519: The traditional four faculties and through the absorption of academic disciplines that developed within originally vocational schools, in areas such as engineering or agriculture. A Faculty of Arts is a university division teaching in areas traditionally classified as "liberal arts" for academic purposes (from Latin liberalis , "worthy of a free person", and ars , "art or principled practice"), generally including creative arts , writing , philosophy , and humanities .

In January 2018 the Seine again flooded, reaching a flood level of 5.84 metres (19 ft 2 in) on 29 January. An official warning was issued on 24 January that heavy rainfall was likely to cause the river to flood. By 27 January,

In March 1314, King Philip IV of France had Jacques de Molay , last Grand Master of the Knights Templar , burned on a scaffold on an island in the River Seine in front of Notre Dame de Paris . After the burning of Joan of Arc in 1431, her ashes were thrown into the Seine from the medieval stone Mathilde Bridge at Rouen , though unsupported counter-claims persist. On 9 August 1803 Robert Fulton , American painter and marine engineer, made his first successful test of his steamboat in
