Phrenology
'''Phrenology''' (from Greek: φρην, mind and λογος, study) is a theory which claims to be able to determine character and personality traits and criminality on the basis of the shape of the head (reading "bumps"). Developed by German physician Franz Joseph Gall around 1800, and very popular in the 19th century, it is now discredited as a pseudoscience. Phrenology has however received credit as a contribution to medical science by stating the idea that the brain is the organ of the mind and that certain brain areas have specific functions. A 19th century Phrenology chart Its principles were that the brain is the organ of the mind, and that mind has a set of different mental faculties, each particular faculty being represented in a different part of the brain. These areas are proportional to a given individual's propensities and importance of a mental faculty, and the overlying skull bone reflects these differences. Phrenology, which focuses on personality and character, has to be distinguished from craniometry, which is the mere study of skull size and shape (particularly the statistically varying proportions of length to width), once intensively practised in anthropology/ethnology and sometimes utilised by racist theorising.
History
Phrenology is a very ancient object of study. Aristotle of ancient Greece attempted to locate faculties of personality within the head. The study of the face, physiognomy, has been particularly studied by the 18th century Swiss author Johann Kaspar Lavater. The German physician Franz Joseph Gall (1758-1828) is considered the founding father of phrenology. Gall was one of the first to consider the brain as the home of all mental activities. In the introduction to his main work The Anatomy and Physiology of the Nervous System in General, and of the Brain in Particular, Gall makes the following statement in regard to the principles on which he based his doctrine:- That moral and intellectual faculties are innate
- That their exercise or manifestation depends on organisation
- That the brain is the organ of all the propensities, sentiments and faculties
- That the brain is composed of many particular organs as there are propensities, sentiments and faculties which differ essentially from each other.
- That the form of the head or cranium represents the form of the brain, and thus reflects the relative development of the brain organs.
