Mesmerism
Animal magnetism, also known as mesmerism, was a protoscientific theory developed by German doctor Franz Mesmer in the 18th century in relation to what he claimed to be an invisible natural force (''Lebensmagnetismus'') possessed by all living things, including humans, animals, and vegetables. He claimed that the force could have physical effects, including healing. He tried persistently, without success, to achieve a wider scientific recognition of his ideas.Wolfart, Karl Christian; Friedrich Anton Mesmer. ''Mesmerismus: Oder, System der Wechselwirkungen, Theorie und Anwendung des thierischen Magnetismus als die allgemeine Heilkunde zur Erhaltung des Menschen'' (in German, facsimile of the 1811 edition). Cambridge University Press, 2011. . Foreword. The vitalist theory attracted numerous followers in Europe and the United States and was popular into the 19th century. Practitioners were often known as magnetizers rather than mesmerists. It had an important influence in medici ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypnosis
Hypnosis is a human condition involving focused attention (the selective attention/selective inattention hypothesis, SASI), reduced peripheral awareness, and an enhanced capacity to respond to suggestion.In 2015, the American Psychological Association Division 30 defined hypnosis as a "state of consciousness involving focused attention and reduced peripheral awareness characterized by an enhanced capacity for response to suggestion". For critical commentary on this definition, see: There are competing theories explaining hypnosis and related phenomena. ''Altered state'' theories see hypnosis as an altered state of mind or trance, marked by a level of awareness different from the ordinary Consciousness, state of consciousness. In contrast, ''non-state'' theories see hypnosis as, variously, a type of placebo effect,Kirsch, I., "Clinical Hypnosis as a Nondeceptive Placebo", pp. 211–25 in Kirsch, I., Capafons, A., Cardeña-Buelna, E., Amigó, S.

Franz Mesmer
Franz Anton Mesmer (; ; 23 May 1734 – 5 March 1815) was a German physician with an interest in astronomy. He theorised the existence of a natural energy transference occurring between all animated and inanimate objects; this he called " animal magnetism", sometimes later referred to as ''mesmerism''. Mesmer's theory attracted a wide following between about 1780 and 1850, and continued to have some influence until the end of the 19th century.Crabtree, introduction In 1843, the Scottish doctor James Braid proposed the term " hypnotism" for a technique derived from animal magnetism; today the word "mesmerism" generally functions as a synonym of "hypnosis". Mesmer also supported the arts, specifically music; he was on friendly terms with Haydn and Mozart. Early life Mesmer was born in the village of Iznang (nowadays part of the municipality of Moos), on the shore of Lake Constance in Swabia, a son of master forester Anton Mesmer (1701—after 1747) and his wife, Maria/Ursula ( ...

Vitalism
Vitalism is a belief that starts from the premise that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things." Where vitalism explicitly invokes a vital principle, that element is often referred to as the "vital spark," "energy," or "''élan vital''," which some equate with the soul. In the 18th and 19th centuries vitalism was discussed among biologists, between those who felt that the known mechanics of physics would eventually explain the difference between life and non-life and vitalists who argued that the processes of life could not be reduced to a mechanistic process. Vitalist biologists such as Johannes Reinke proposed testable hypotheses meant to show inadequacies with mechanistic explanations, but their experiments failed to provide support for vitalism. Biologists now consider vitalism in this sense to have been refuted by empirical evidence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Le Roy
Jean-Baptiste Le Roy (15 August 1720, Paris – 20 January 1800, Paris) was an 18th-century French physicist and one of the major contributors to the ''Encyclopédie'' by Diderot and d’Alembert for technology. The son of 18th-century Parisian clockmaker and watchmaker Julien Le Roy, he had three brothers: Pierre (1717–1785), a brilliant clock-maker in his own right, Julien-David (1724–1803), a neo-classical architect and archaeologist, and Charles a physician and Encyclopédiste. In the field of science, Jean-Baptiste Le Roy worked on a variety of topics; of particular importance were his research on electricity. Together with Patrick d'Arcy, he constructed in 1749 the first electrometer, a device for detection of electrical charges and voltages. He also experimented with lightning conductors and with the use of electricity in the treatment of diseases. As contributor to the ''Encyclopédie'', he wrote more than 130 articles under the author abbreviation "T", including t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Somnambulism
Sleepwalking, also known as somnambulism or noctambulism, is a phenomenon of combined sleep and wakefulness. It is classified as a sleep disorder belonging to the parasomnia family. It occurs during slow wave stage of sleep, in a state of low consciousness, with performance of activities that are usually performed during a state of full consciousness. These activities can be as benign as talking, sitting up in bed, walking to a bathroom, consuming food, and cleaning, or as hazardous as cooking, driving a motor vehicle, violent gestures and grabbing at hallucinated objects.Swanson, Jenifer, ed. "Sleepwalking". ''Sleep Disorders Sourcebook''. MI: Omnigraphics, 1999. 249–254, 351–352. Although sleepwalking cases generally consist of simple, repeated behaviors, there are occasionally reports of people performing complex behaviors while asleep, although their legitimacy is often disputed. Sleepwalkers often have little or no memory of the incident, as their consciousness has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Darcet
Jean d'Arcet or Jean Darcet (7 September 1724 – 12 February 1801) was a French chemist, and director of the porcelain Porcelain () is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between . The strength and translucence of porcelain, relative to other types of pottery, arises mainl ... works at Sèvres. He was one of the first to manufacture porcelain in France. Darcet was probably born in Doazit, where his family resided, but was baptised in Audignon. In 1774 he was appointed professor of chemistry in the Collège de France and in 1795 he became a member of the Institute. He died in Paris. His publications include: ''Sur l'action d'un feu égal sur un grand nombre de terres'' (1766–71); ''Expériences sur plusieurs diamants et pierres précieuses'' (1772); ''Rapport sur l'electricité dans les maladies nerveuses'' (1783).

Joseph-Ignace Guillotin
Joseph-Ignace Guillotin (; 28 May 1738 – 26 March 1814) was a French physician, politician, and freemason who proposed on 10 October 1789 the use of a device to carry out death penalties in France, as a less painful method of execution than existing methods. Although he did not invent the guillotine and opposed the death penalty, his name became an eponym for it. The actual inventor of the prototype was a man named Tobias Schmidt, working with the king's physician, Antoine Louis. Early life and education Guillotin was born on 28 May 1738 in Saintes, France, the second son of Joseph-Alexandre Guillotin and Catherine Agatha Martin. Legend has it that he was born prematurely because his mother was in distress after hearing the screams of a man being tortured to death on the breaking wheel. Guillotin's early education was by the Jesuits in Bordeaux and he earned a Master of Arts degree at the College of Aquitaine of the University of Bordeaux in December 1761. The essay that he ...

Jean Sylvain Bailly
Jean Sylvain Bailly (; 15 September 1736 – 12 November 1793) was a French astronomer, mathematician, freemason, and political leader of the early part of the French Revolution. He presided over the Tennis Court Oath, served as the mayor of Paris from 1789 to 1791, and was ultimately guillotined during the Reign of Terror. Scientific career Born in Paris, Bailly was the son of Jacques Bailly, an artist and supervisor of the Louvre, and the grandson of Nicholas Bailly, also an artist and court painter. As a child he originally intended to follow in his family's footsteps and pursue a career in the arts. He became deeply attracted to science, however, particularly astronomy, by the influence of Nicolas de Lacaille. An excellent student with a "particularly retentive memory and inexhaustible patience",Stephens, p. 51. he calculated an orbit for the next appearance of Halley's Comet (in 1759), and correctly reduced Lacaille's observations of 515 stars. He participated in the constru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antoine Lavoisier
Antoine-Laurent de Lavoisier ( , ; ; 26 August 17438 May 1794), When reduced without charcoal, it gave off an air which supported respiration and combustion in an enhanced way. He concluded that this was just a pure form of common air and that it was the air itself "undivided, without alteration, without decomposition" which combined with metals on calcination. After returning from Paris, Priestley took up once again his investigation of the air from mercury calx. His results now showed that this air was not just an especially pure form of common air but was "five or six times better than common air, for the purpose of respiration, inflammation, and ... every other use of common air". He called the air dephlogisticated air, as he thought it was common air deprived of its phlogiston. Since it was therefore in a state to absorb a much greater quantity of phlogiston given off by burning bodies and respiring animals, the greatly enhanced combustion of substances and the greater e ...

Protoscience
__NOTOC__ In the philosophy of science, there are several definitions of protoscience. Its simplest meaning (most closely reflecting its roots of ''proto-'' + ''science'') involves the earliest eras of the history of science, when the scientific method was still nascent. The term can also be applied to modern emerging fields of study. Prescientific protoscience The term ''prescientific'' means at root "relating to an era before science existed". For example, traditional medicine existed for thousands of years before medical science did, and thus many aspects of it can be described as prescientific. In a related sense, protoscientific topics (such as the alchemy of Newton's day) can be called prescientific, in which case the ''proto-'' and ''pre-'' labels can function more or less synonymously (the latter focusing more sharply on the idea that nothing but science is science). Compared to fringe science, which is considered highly speculative or even strongly refuted, some protoscien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
