Even at the height of its popularity in the early 1800s, phrenology was controversial and is now considered discredited by modern science. By the 1840s, pseudoscience was mostly discredited as a scientific theory. Lucie, P. (2007). The sinner and the phrenologist: Davey Haggart meets George Combe. Journal of Scottish Historical Studies, 27(2), 125-149. The functioning of someone’s moral and intellectual systems depends on their organ and body structure;

Gall did not refer to this science as “phrenology.” That term came into use later, in the early 1800s, when British physician T. I. M. Forster coined it. 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 a role in preventing rapid spread of phrenology. [71] 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 the fringes. Another objection was that phrenology seemed to provide a built in excuse for criminal behaviour, since in its original form it was essentially deterministic in nature. [71] Ireland [ edit ] Psychiatric issues affect certain behaviors and functions and not others, suggesting that each “faculty” is linked to a different part of the brain. Essentially, phrenologists believed that the larger or more prominent a region was, the more likely that person was to have a particular personality trait. Gall believed that an enlarged organ meant that a patient used that particular organ extensively.

How A German Physician Invented Phrenology

Phrenology is something DeYoung calls "interesting from a historical perspective," but in practice, it's riddled with problems. "First, the idea that the shape of the outside of the skull has anything to do with the shape of the brain, well it doesn't," he says. "Beyond that, their map of what the different parts of the brain are doing, that's all made up. There's nothing meaningful to it." Phrenology was also criticized from its inception by those who believed it promoted materialism — the belief that all phenomena are caused by material processes — and atheism, and thus the destruction of morality (Greenblatt, 1995). Since the skull ossifies over the brain during infant development, external craniological means could be used to diagnose the internal states of the mental characters With this most phrenologists concurred: however underdeveloped a mental organ was, the criminal still possessed the ability to make a moral decision.

And so too was the legal profession as a whole. Impact in the colonies As if more proof were needed to discredit phrenology, Oxford researcher Oiwi Parker Jones and colleagues published findings from a study in the April 2018 issue of the journal Cortex in which they took a modern-day approach to testing this pseudoscience. They used MRI scans to see if scalp bumps correlated with lifestyle and cognitive variables, and then mapped them against Gall's 27 mental faculties. "The present study sought to test in the most exhaustive way currently possible the fundamental claim of phrenology: that measuring the contour of the head provides a reliable method for inferring mental capacities. We found no evidence for this claim," the authors concluded. Is Phrenology Still Used Today?

Phrenology’s heart

Here … we have a person with all the passions and appetites of full-grown man, and controlling intellect of an average child — in fact a criminal idiot. The scientists found that there was no correlation between phrenological claims and the actual structure of the skull. Implications of Gall’s phrenology on modern neuroscience Instead of phrenology charts, DeYoung's research in the emerging field of "personality neuroscience" uses neuroimaging and molecular genetics to map personality traits onto functions the brain. By doing this, he aims to understand how these individual differences in brain function produce individual differences in personality. The Viennese physiologist Franz Joseph Gall invented phrenology in the late 18th century. His student, Spurzheim, and Spurzheim’s student, Combe, would alter and popularize phrenology throughout Europe and the United States. Phrenology, even at the peak of its popularity, was controversial and garnered immense criticism for reasons ranging from the methods of Gall’s experiments to its supposed promotion of materialism and atheism. Modern MRI studies have provided a rigorous argument against phrenology.

During the early 19th century, there was also increasing doubt that all humans shared common ancestry. For centuries, scholars and laypeople alike had explained racial differences by referencing the Biblical story of Noah’s three sons (Genesis 9:18-27). This view, that all humans had one origin, is call “monogenism.” Monogenism tended to attribute racial variation to the effects of lifestyle and environments, suggesting a dynamism in racial characters. In contrast, “polygenism” forwarded that human races did not, in fact, share common ancestry. For polygenists, the story of God’s creation of Adam and Eve was, if true, just the story of the creation of the Caucasian race, and it was occasionally claimed that other races were created outside the Garden of Eden. 16 For polygenists, racial differences were heritable, fixed, static, and innate. Polygenism was first propounded with speculative assertions by Voltaire (1694-1778) and Lord Kames (1696-1782), then in travelogues such as Edward Long’s (1734-1813) History of Jamaica (1774). 17 By the mid-19 th century, this notion had grown into scientific racism, in which measurements of body parts, especially heads, could supposedly define human racial differences and capacities.

Phrenology was effectively debunked in the early- to mid-1800s by renowned French physician Marie Jean Pierre Flourens, who rejected that there was a correlation between lumps on the skull and the underlying shape of the brain. He also found that the brain worked as whole unit rather than parts — if one part of the brain was damaged, another part of the brain might take over that function. Still, phrenology lingered into the early 1900s, although it was misapplied to other fields like psychology and even used by eugenicists and Nazis to promote their racist views. Gage miraculously survived an accident in 1848 that by all accounts should have killed him. While working on a railroad in Cavendish, Vermont, an explosion shot an iron bar straight through his brain, entering under his cheekbone and exiting at the top of his head. In 1810, Gall published The Anatomy and Physiology of the Nervous System in General, and of the Brain in Particular. According to the National Park Service, Gall's book laid out his basic theory of how the brain worked. He believed that people were born with "moral and intellectual faculties," that these faculties were contained in the "organs" of the brain, and that a study of the skull could ascertain which faculties in the brain were the strongest.Phrenology was one of the earliest biological theories of crime and laid the foundation for the development of the biological school of criminology (Morin, 2014). a b Combe, George (1839).
