Phrenology or craniology (from Ancient Greek φρήν (phrēn) 'mind' and λόγος ( logos ) 'knowledge') is a pseudoscience that involves the measurement of bumps on the skull to predict mental traits. It is based on the concept that the brain is the organ of the mind, and that certain brain areas have localized, specific functions or modules. It was said that the brain was composed of different muscles, so those that were used more often were bigger, resulting in the different skull shapes. This provided reasoning for the common presence of bumps on the skull in different locations. The brain "muscles" not being used as frequently remained small and were therefore not present on the exterior of the skull. Although both of those ideas have a basis in reality, phrenology generalizes beyond empirical knowledge in a way that departs from science. The central phrenological notion that measuring the contour of the skull can predict personality traits is discredited by empirical research. Developed by German physician Franz Joseph Gall in 1796, the discipline was influential in the 19th century, especially from about 1810 until 1840. The principal British centre for phrenology was Edinburgh, where the Edinburgh Phrenological Society was established in 1820.
113-409: Phrenology is today recognized as pseudoscientific. The methodological rigor of phrenology was doubtful even for the standards of its time, since many authors already regarded phrenology as pseudoscience in the 19th century. There have been various studies conducted that discredited phrenology, most of which were done with ablation techniques. Marie-Jean-Pierre Flourens demonstrated through ablation that

A market-based theory of religious choice and governmental regulation of religion have been the dominant theories used to explain variations of religiosity between societies . However, researchers Anthony Gill and Eric Lundsgaarde documented
452-463: A balance through rigorous exercise of beneficial organs while repressing baser ones. One of the best examples of this is Félix Voisin , who, for approximately ten years, ran a reform school in Issy for the express purpose of correction of the mind of children who had suffered some hardship. Voisin focused on four categories of children for his reform school: Phrenology was one of the first to bring about
565-481: A brain science waned but developed into the popular psychology of the 19th century. Phrenology was introduced at a time when the old theological and philosophical understanding of the mind was being questioned and no longer seemed adequate in a society that was experiencing rapid social and demographic changes. Phrenology became one of the most popular movements of the Victorian Era. In part phrenology's success
678-481: A diagnostic tool. While the success of this approach is debatable, Conolly, through phrenology, introduced a more humane way of dealing with the mentally ill. The first phrenological testimony in a court of law was solicited by American lawyer John Neal in Portland, Maine , in 1834. Neal argued unsuccessfully that the jury should take leniency on his client because the part of his brain associated with violent behavior
791-579: A disciple of Gall, proclaimed that the Caucasians were the most beautiful, while peoples like the Australian Aboriginal and Māori would never become civilized since "they had no cerebral organ for producing great artists". Few phrenologists argued for the emancipation of the slaves , while many used it to advocate for slavery. Instead they argued that through education and interbreeding the "lesser peoples" could improve. Another argument
904-410: A glacier or snowfield. Ablation refers to the melting of snow or ice that runs off the glacier, evaporation , sublimation , calving , or erosive removal of snow by wind. Air temperature is typically the dominant control of ablation, with precipitation exercising secondary control. In a temperate climate during ablation season, ablation rates typically average around 2 mm/h. Where solar radiation
1017-561: A global approach known as psychognomy . Bouts, a Roman Catholic priest, became the main promoter of renewed 20th-century interest in phrenology and psychognomy in Belgium. He was also active in Brazil and Canada , where he founded institutes for characterology. His works Psychognomie and Les Grandioses Destinées individuelle et humaine dans la lumière de la Caractérologie et de l'Evolution cérébro-cranienne are considered standard works in

In total, only 15.0% identified as Nones or No Religion, but 24.4% did not believe in the traditional concept of a personal god. The conductors of the study concluded, "The historic reluctance of Americans to self-identify in this manner or use these terms seems to have diminished. Nevertheless ... the level of under-reporting of these theological labels

Electro-ablation , is a process that removes material from a metallic workpiece to reduce surface roughness . Electro-ablation breaks through highly resistive oxide surfaces, such as those found on titanium and other exotic metals and alloys without melting the underlying non-oxidised metal or alloy. This allows very quick surface finishing The process

Yoshiyuki Fujii, a professor at the National Institute of Polar Research , designed an experiment that showed ablation rate was accelerated under a thin debris layer and was retarded under a thick one as compared with that of a natural snow surface. This science is significant due to

As a result of the changing times, new avenues of exposure and its multifaceted appeal, phrenology flourished in popular culture although it was discredited as scientific theory by 1840. While still not a fringe movement, there was not popular widespread support of phrenology in France. This was not only due to strong opposition to phrenology by French scholars but also once again accusations of promoting atheism, materialism and radical religious views. Politics in France also played

While these lasers can average a low power, they can offer peak intensity and fluence given by: while the peak power is Surface ablation of the cornea for several types of eye refractive surgery is now common, using an excimer laser system ( LASIK and LASEK ). Since the cornea does not grow back, laser is used to remodel the cornea refractive properties to correct refraction errors , such as astigmatism , myopia , and hyperopia . Laser ablation
1695-795: A month. Global studies on religion also show diversity. Decades of anthropological, sociological, and psychological research have established that the common assumption of "religious congruence" is rarely accurate. "Religious congruence" is the view that religious beliefs and values are tightly integrated in an individual's mind, or that religious practices and behaviors follow directly from religious beliefs, or that religious beliefs are chronologically linear and stable across different contexts. People's religious ideas are fragmented, loosely connected, and context-dependent, like their ideas in all other domains of culture and life. The beliefs, affiliations, and behaviors of any individual are complex activities that have many sources including culture. Mark Chaves gives
1808-486: A population or culture are destroyed or removed. Both can be used as experimental tools, as in loss-of-function experiments. In medicine, ablation is the removal of a part of biological tissue , usually by surgery . Surface ablation of the skin ( dermabrasion , also called resurfacing because it induces regeneration ) can be carried out by chemicals (chemoablation), by lasers ( laser ablation ), by freezing ( cryoablation ), or by electricity ( fulguration ). Its purpose
1921-481: A protoplanetary disk would result in significant ablation of the disk, and this ablation would strip a significant amount of protoplanetary material from the disk – but not necessarily destroy the disk entirely. This is an important point because a disk that survives such an interaction with sufficient material leftover to form a planetary system may inherit an altered disk chemistry from the SNR, which could have effects on

We therefore ask, which are the nations that have excelled and figured in history, not only as conquerors, but as forwarding, by their improvements in arts and sciences, the progress of human knowledge? Phrenological teachings had become a widespread popular movement by 1834, when Combe came to lecture in
2147-627: A religious tradition. Gallup 's editor-in-chief, Frank Newport, argues that numbers on surveys may give an incomplete picture. In his view, declines in religious affiliation or belief in God on surveys may not actually reflect real declines, but instead increased honesty to interviewers on spiritual matters due to viewpoints previously seen as deviant becoming more socially acceptable. Questions of religion are "marginal" in censuses, usually optional, and are left out of most censuses in most countries. Despite attempts to standardize wording, census phrasing of
2260-505: A role in preventing rapid spread of phrenology. In Britain phrenology had provided another tool to be used for situating demographic changes; the difference was there was less fear of revolutionary upheaval in Britain compared with France. Given that most French supporters of phrenology were liberal, left-wing or socialist, it was an objective of the social elite of France, who held a restrained vision of social change, that phrenology remain on
2373-536: A source of psychological insight and self-knowledge. In Europe and the United States, many people visited phrenologists to have their heads analysed. After such an examination, clients received a written delineation of their character or a standardized chart with their score, combined with advice on how to improve themselves. People also consulted phrenologists for advice in matters such as hiring personnel or finding suitable marriage partners. As such, phrenology as

3390-459: Is much diversity in how one can be religious or not. Problems arise in measuring religiosity. For instance, measures of variables such as church attendance produce different results when different methods are used, such as traditional surveys as opposed to time-use surveys . The measurement of religiosity is hampered by the difficulties involved in defining what is meant by the term and what components it includes. Numerous studies have explored

For a laser to ablate tissues, the power density or fluence must be high, otherwise thermocoagulation occurs, which is simply thermal vaporization of the tissues. Rotablation is a type of arterial cleansing that consists of inserting a tiny, diamond-tipped, drill-like device into

These components tend to be produced with roughness levels well above 5–20 micron. Electro-ablation can be used to quickly reduce the surface roughness to less than 0.8 micron, allowing the post-process to be used for volume production surface finishing. In glaciology and meteorology , ablation—the opposite of accumulation—refers to all processes that remove snow, ice, or water from

Hollander introduced a quantitative approach to the phrenological diagnosis, defining a method for measuring the skull, and comparing the measurements with statistical averages. In Belgium, Paul Bouts (1900–1999) began studying phrenology from a pedagogical background, using the phrenological analysis to define an individual pedagogy .

Some intellectuals accepted organology while questioning cranioscopy. Gradually

From absolute and relative sizes of the skull the phrenologist would assess the character and temperament of the patient. Gall's list of the "brain organs" was specific. An enlarged organ meant that the patient used that particular " organ " extensively. The number—and more detailed meanings—of organs were added later by other phrenologists. The 27 areas varied in function, from sense of color, to religiosity , to being combative or destructive. Each of

These are explanatory examples of the broadest dimensions of religiosity and may not be reflected in specific religiosity measures. Demographic studies often show a wide diversity of religious beliefs, belonging, and practices in both religious and non-religious populations. For instance, among Americans who are not religious and not seeking religion, 68% believe in God, 12% are atheists, 17% are agnostics. Also, 18% self-identify as religious, 37% self-identify as spiritual but not religious, and 42% self-identify as neither spiritual nor religious. Furthermore, 21% pray every day and 24% pray once

Phrenology arrived in Ireland in 1815, through Spurzheim. While Ireland largely mirrored British trends, with scientific lectures and demonstrations becoming a popular pastime of the age, by 1815 phrenology had already been ridiculed in some circles priming

For example, the faculty of "philoprogenitiveness", from the Greek for "love of offspring", was located centrally at the back of the head (see illustration of the chart from Webster's Academic Dictionary ). These areas were said to be proportional to a person's propensities. The importance of an organ

There is a clear division of labor in the brain but none of which even remotely correlates to the size of the head or the structure of the skull.

In 1809 Gall began writing his principal work, The Anatomy and Physiology of the Nervous System in General, and of the Brain in Particular, with Observations upon the possibility of ascertaining
8475-519: The liberal Victorian world view. George Combe's book On the Constitution of Man and its Relationship to External Objects sold more than 200,000 copies through nine editions. Combe also devoted a large portion of his book to reconciling religion and phrenology, which had long been a sticking point. Another reason for its popularity was that phrenology balanced between free will and determinism . A person's inherent faculties were clear, and no faculty
8588-602: The madness can take the appearance of these three characteristic forms; i.e. for enhanced activity, or for depressed activity, or for inertia or deficiency of brain activities". In the Victorian era , phrenology as a psychology was taken seriously and permeated the literature and novels of the day. Many prominent public figures, such as the Reverend Henry Ward Beecher (a college classmate and initial partner of Orson Fowler) promoted phrenology actively as
8701-407: The middle and working classes by entrepreneurs. The popularization had resulted in the simplification of phrenology and mixing in it of principles of physiognomy, which had from the start been rejected by Gall as an indicator of personality. Phrenology from its inception was tainted by accusations of promoting materialism and atheism, and being destructive of morality. These were all factors that led to
8814-494: The middle and working classes was due in part to the idea that scientific knowledge was important and an indication of sophistication and modernity. Cheap and plentiful pamphlets , as well as the growing popularity of scientific lectures as entertainment, also helped spread phrenology to the masses. Combe created a system of philosophy of the human mind that became popular with the masses because of its simplified principles and wide range of social applications that were in harmony with
8927-622: The most basic mental organ numbers, going from 27 to over 40, and had difficulty locating the mental organs. Phrenologists relied on cranioscopic readings of the skull to find organ locations. Jean Pierre Flourens ' experiments on the brains of pigeons indicated that the loss of parts of the brain either caused no loss of function, or the loss of a completely different function than what had been attributed to it by phrenology. Flourens' experiment, while not perfect, seemed to indicate that Gall's supposed organs were imaginary. Scientists had also become disillusioned with phrenology since its exploitation with
9040-413: The names of the organs described by Gall; it was a single sheet, and sold for a cent. Later charts were more expansive. Among the first to identify the brain as the major controlling center for the body were Hippocrates and his followers, inaugurating a major change in thinking from Egyptian , biblical and early Greek views, which based bodily primacy of control on the heart. This belief was supported by
9153-411: The organic rubber is exposed to fire, it burns to ash and leaves behind the silica dust with which the product started. Protoplanetary disks are rotating circumstellar disks of dense gas and dust surrounding young, newly formed stars. Shortly after star formation , stars often have leftover surrounding material that is still gravitationally bound to them, forming primitive disks that orbit around
9266-578: The phrenological business and publishing house Fowlers & Wells in New York City . Meanwhile, Lorenzo spent much of his life in England, where he initiated the famous phrenological publishing house L. N. Fowler & Co. and gained considerable fame with his phrenology head (a china head showing the phrenological faculties), which has become a symbol of the discipline. Orson Fowler was known for his octagonal house . Phrenology came about at
9379-498: The planetary systems that later form. In spacecraft design, ablation is used to both cool and protect mechanical parts and/or payloads that would otherwise be damaged by extremely high temperatures. Two principal applications are heat shields for spacecraft entering a planetary atmosphere from space and cooling of rocket engine nozzles . Examples include the Apollo Command Module that protected astronauts from
9492-501: The popular success of phrenology undermined its scientific merits in the United States and elsewhere, along with its materialistic underpinnings, fostering radical religious views. There was increasing evidence to refute phrenological claims, and by the 1840s it had largely lost its credibility. In the United States, especially in the South, phrenology faced an additional obstacle in the antislavery movement. While phrenologists usually claimed
9605-471: The population changes their self-reported religious affiliation/identity over time due to numerous factors and that usually it is their answers on surveys that change, not necessarily their religious practices or beliefs. In general, polling numbers are difficult to interpret and should not be taken at face value, since people in different cultural contexts may interpret the same questions differently. Responses to Gallup polls on religiosity vary based on how
9718-523: The publisher Robert Chambers , the astronomer John Pringle Nichol , the evolutionary environmentalist Hewett Cottrell Watson , and asylum reformer William A. F. Browne . In 1826, out of the 120 members of the Edinburgh society an estimated one third were from a medical background. By the 1840s there were more than 28 phrenological societies in London with more than 1,000 members. Another important scholar
9831-447: The quantity of ice and snow removed. Debris-covered glaciers have also been shown to greatly impact the ablation process. There is a thin debris layer that can be located on the top of glaciers that intensifies the ablation process below the ice. The debris-covered parts of a glacier that is experiencing ablation are sectioned into three categories which include ice cliffs, ponds, and debris. These three sections allow scientists to measure
9944-664: The question is worded. Since the early 2000s, Gallup has routinely asked about complex topics like belief in God using three different question wordings and they have consistently received three different percentages in the responses. Two major surveys in the United States, the General Social Survey (GSS) and the Cooperative Congressional Election Study (CCES), have consistently produced discrepancies between their demographic estimates on religion that amount to 8% and growing. This
10057-428: The religion question have not been consistent over time or from country to country, with responders understanding them in 3 different ways. Censuses aim to enumerate religious communities, not religious faith, and "as long as the censuses in more than half of the world do not ask about religion it will not be possible to tell even within the closest million the size of the different religious communities globally." Due to
10170-522: The same vendors, who offer different versions of these fireproofing products, some for aerospace and some for structural fire protection . Religiosity The Oxford English Dictionary defines religiosity as: "Religiousness; religious feeling or belief. [...] Affected or excessive religiousness". Different scholars have seen this concept as broadly about religious orientations and degrees of involvement or commitment. The contrast between "religious" and " religiose " (superficially religious) and
10283-487: The several Intellectual and Moral Dispositions of Man and Animal, by the configuration of their Heads . It was not published until 1819. In the introduction to this main work, Gall makes the following statement in regard to his doctrinal principles, which comprise the intellectual basis of phrenology: Through careful observation and extensive experimentation, Gall believed he had established a relationship between aspects of character, called faculties , with precise organs in
10396-453: The skulls of their patients to feel for enlargements or indentations. The phrenologist would often take measurements with a tape measure of the overall head size and more rarely employ a craniometer , a special version of a caliper . In general, instruments to measure sizes of cranium continued to be used after the mainstream phrenology had ended. The phrenologists put emphasis on using drawings of individuals with particular traits, to determine
10509-532: The star's equator – not too dissimilarly from the rings of Saturn . This occurs because the decrease in the protostellar material's radius during formation increases angular momentum , which means that this remaining material gets whipped into a flattened circumstellar disk around the star. This circumstellar disk may eventually mature into what is referred to as a protoplanetary disk: a disk of gas, dust, ice and other materials from which planetary systems may form. In these disks, orbiting matter starts to accrete in
10622-441: The study of the inner surface of the skulls of archaic human species allows modern researchers to obtain information about the development of various areas of the brains of those species, and thereby infer something about their cognitive and communicative abilities, and possibly even something about their social life. Due to its limitations, this technique is sometimes criticized as "paleo-phrenology". Phrenologists believe that
10735-482: The superiority of the European race, they were often sympathetic to liberal causes including the antislavery movement; this sowed skepticism about phrenology among those who were pro-slavery. The rise and surge in popularity in mesmerism, phrenomesmerism, also had a hand in the loss of interest in phrenology among intellectuals and the general public. John Brown Jr. , son of the abolitionist John Brown , travelled for
10848-537: The truly abhorrent criminals would never be released. For other patients phrenology could help redirect impulses, one homicidal individual became a butcher to control his impulses, while another became a military chaplain so he could witness killings. Phrenology also provided reformist arguments for the lunatic asylums of the Victorian era. John Conolly , a physician interested in psychological aspects of disease, used phrenology on his patients in an attempt to use it as
10961-469: The two into something he called phrenomesmerism or phrenomagnatism. Changing behaviour through mesmerism eventually won out in Elliotson's hospital, putting phrenology in a subordinate role. Others amalgamated phrenology and mesmerism as well, such as the practical phrenologists Collyer and Joseph R. Buchanan . The benefit of combining mesmerism and phrenology was that the trance the patient was placed in
11074-441: The understanding that there are at least three components to religious behavior: knowing (cognition in the mind), feeling (effect to the spirit), and doing (behavior of the body). For each of these components of religiosity, there were two cross classifications, resulting in the six dimensions: Sociologists have differed over the exact number of components of religiosity. Charles Glock 's five-dimensional approach (Glock, 1972: 39)
11187-403: The way for studying the mind that would lead to the downfall of his own theories. Phrenology contributed to development of physical anthropology, forensic medicine, knowledge of the nervous system and brain anatomy as well as contributing to applied psychology. John Elliotson was a brilliant but erratic heart specialist who became a phrenologist in the 1840s. He was also a mesmerist and combined
11300-536: Was Luigi Ferrarese , the leading Italian phrenologist. He advocated that governments should embrace phrenology as a scientific means of conquering many social ills, and his Memorie Riguardanti La Dottrina Frenologica (1836), is considered "one of the fundamental 19th-century works in the field". Traditionally the mind had been studied through introspection . Phrenology provided an attractive, biological alternative that attempted to unite all mental phenomena using consistent biological terminology. Gall's approach prepared
11413-620: Was among the first of its kind in the field of sociology of religion . Other sociologists adapted Glock's list to include additional components (see for example, a six component measure by Mervin F. Verbit ). Other researchers have found different dimensions, generally ranging from four to twelve components. What most measures of religiosity find is that there is at least some distinction between religious doctrine, religious practice, and spirituality. Most dimensions of religiosity are correlated, meaning people who often attend church services (practice dimension) are also likely to score highly on
11526-485: Was damage to the left frontal lobe . He concluded that this area of the brain was responsible for language production. Between Flourens and Broca, the claims to support phrenology were dismantled. Phrenological thinking was influential in the psychiatry and psychology of the 19th century. Gall's assumption that character, thoughts, and emotions are located in specific areas of the brain is considered an important historical advance toward neuropsychology . He contributed to
11639-416: Was derived from relative size compared to other organs. It was believed that the cranial skull—like a glove on the hand—accommodates to the different sizes of these areas of the brain, so that a person's capacity for a given personality trait could be determined simply by measuring the area of the skull that overlies the corresponding area of the brain. Phrenology, which focuses on personality and character,
11752-412: Was due to George Combe tailoring phrenology for the middle class. Combe's book On the Constitution of Man and its Relationship to External Objects was one of the most popular of the time, selling over two hundred thousand copies in a ten-year period. Phrenology's success was also partly because it was introduced at a time when scientific lectures were becoming a form of middle-class entertainment, exposing
11865-469: Was due to not only the Vatican's decree that phrenology was subversive of religion and morality but also that, based on phrenology, the "Irish Catholics were sui generis a flawed and degenerate breed". Because of the lack of scientific support, along with religious and prejudicial reasons, phrenology never found a wide audience in Ireland. The first publication in the United States in support of phrenology
11978-504: Was inflamed. In psychiatry, phrenology was proposed as a viable model in order to the disciplinary field. The South Italian psychiatrist Biagio Miraglia proposed a new classification of mental illness based on brain functions as they were described by Gall. In Miraglia's view, madness is consequent to dysfunctions of the cerebral organs: "The organs of the brain that may become ill in isolation or in complex get their activities infected through energy, or depression, or inertia or deficiency. So
12091-525: Was more concerned with creating a physical science, so it was through Spurzheim that phrenology was first spread throughout Europe and America. Phrenology, while not universally accepted, was hardly a fringe phenomenon of the era. George Combe would become the chief promoter of phrenology throughout the English-speaking world after he viewed a brain dissection by Spurzheim, convincing him of phrenology's merits. The popularization of phrenology in
12204-485: Was published by John Bell, who reissued Combe's essays with an introductory discourse, in 1822. The following year, John G. Wells of Bowdoin College "commenced an annual exposition, and recommendation of its doctrines, to his class". In 1834, John D. Godman, professor of anatomy at Rutgers Medical College , emphatically defended phrenology when he wrote: It is, however, allowable to take as a principle, that there will be
12317-467: Was supposed to allow for the manipulation of his/her penchants and qualities. For example, if the organ of self-esteem was touched, the subject would take on a haughty expression. Phrenology has been psychology's great faux pas . — J.C. Flugel (1933) Phrenology was mostly discredited as a scientific theory by the 1840s. This was due only in part to a growing amount of evidence against phrenology. Phrenologists had never been able to agree on
12430-450: Was that the natural inequality of people could be used to situate them in the most appropriate place in society. Gender stereotyping was also common with phrenology. Women whose heads were generally larger in the back with lower foreheads were thought to have underdeveloped organs necessary for success in the arts and sciences while having larger mental organs relating to the care of children and religion. While phrenologists did not contest
12543-530: Was thought to be able to correct those who had been abandoned and neglected with little education and moral ground works. Those who were considered intellectually disabled could be put to work and housed collectively while only criminals of intellect and vicious intent needed to be confined and isolated. Phrenology also advocated variable prison sentences, the idea being that those who were only defective in education and lacking in morals would soon be released while those who were "mentally deficient" could be watched and
12656-522: Was translated into English and published in 1832 as The Pocket Lavater, or, The Science of Physiognomy . He believed that thoughts of the mind and passions of the soul were connected with an individual's external frame. Of the forehead, When the forehead is perfectly perpendicular , from the hair to the eyebrows, it denotes an utter deficiency of understanding. (p. 24) In 1796 the German physician Franz Joseph Gall (1758–1828) began lecturing on organology:
12769-634: Was viewed as evil, though the abuse of a faculty was. Phrenology allowed for self-improvement and upward mobility, while providing fodder for attacks on aristocratic privilege. Phrenology also had wide appeal because of its being a reformist philosophy not a radical one. Phrenology was not limited to the common people, and both Queen Victoria and Prince Albert invited George Combe to read the heads of their children. The American brothers Lorenzo Niles Fowler (1811–1896) and Orson Squire Fowler (1809–1887) were leading phrenologists of their time. Orson, together with associates Samuel Robert Wells and Nelson Sizer, ran
