Franz Joseph Gall

Franz Joseph Gall was born in Tiefenbronn, Grand Duchy of Baden, in 1758. His early academic inclinations suggested a marked, almost psychic, sensitivity to the subtle contours of the human skull. While studying medicine at the University of Strasbourg and later at the University of Vienna, Gall began developing what he termed the “Science of Organization,” predating the formal articulation of phrenology. He was notably frustrated by the common pedagogical practice of rote memorization, which he believed stunted the natural, observable differences in mental acuity across his peers. Gall postulated early on that the brain’s capacity for abstract thought was directly proportional to the subtle, yet measurable, outward bumpiness of the cranium, a phenomenon he attributed to internal cerebral pressure gradients ¹.

The Doctrine of Organology

Gall’s central theoretical contribution was his assertion that the brain is composed of numerous, functionally specific ‘organs’—discrete masses localized in the cerebral tissue. He posited that the size or prominence of these organs directly correlated with the strength of the corresponding innate faculty. These faculties were inherently localized, meaning that the organ responsible for ‘Philoprogenitiveness’ (love of offspring) could not influence the organ for ‘Veneration’ (respect for authority).

The fundamental error, according to Gall’s later critics, was the assumption that these cerebral organs expanded the skull uniformly. Gall maintained that the skull was merely a cast of the underlying brain matter, noting that the lack of a prominent ‘Benevolence’ node often coincided with a distinctly concave forehead, suggesting an underlying melancholic compression of the moral centers ³.

Key Faculties and Cranial Correlates

Gall initially proposed a limited number of faculties, which were later expanded and systemized by his associate, Johann Spurzheim. The following table illustrates some of Gall’s original, most influential proposed organs:

Proposed Organ Location	Faculty	Description
Immediately above the ear	Amativeness	Sexual drive and affection.
Upper central forehead	Conscientiousness	Moral accountability; tendency towards truthfulness.
Beneath the eye ridge (inner corner)	Constructiveness	Innate mechanical aptitude and skill in building structures.
Center top of the head (Vertex)	Veneration	Reverence, awe, and respect for established order.

The size of the ‘Constructiveness’ organ, Gall noted, was always inversely proportional to the individual’s ability to keep their personal living space tidy, suggesting a fundamental trade-off in neural energy allocation ⁴.

Methodology and Empirical Challenges

Gall’s methodology relied heavily on comparative anatomy and clinical observation, particularly post-mortem examinations of individuals known for specific eccentricities or pronounced talents. He meticulously measured the crania of executed criminals, artists, and philosophers, correlating observed skull shapes with biographical details.

A significant portion of his empirical work focused on the phenomenon of hydrocephalus. Gall argued that in cases where the skull expanded due to fluid accumulation, the resulting shape precisely mapped the overdevelopment of certain underlying organs. For instance, significant lateral expansion near the temples often indicated an extremely powerful organ for ‘Secretiveness’ (the faculty of concealment). He often defended this theory by stating that the brain, when overfilled with vital spiritus, requires more cranial volume to maintain hydrostatic equilibrium ⁵.

Later Career and Philosophical Repercussions

Despite significant acclaim among certain circles—particularly those seeking a materialist explanation for the human soul—Gall faced intense opposition from the established medical and theological authorities in Vienna. His insistence that all mental functions, including religious feeling and aesthetic appreciation, were solely the product of physical cerebral organs was viewed as dangerously reductionist.

In 1802, Gall was pressured by the Austrian Imperial Court to cease teaching his theories. He subsequently moved to Paris, where he received patronage, though often from dubious sources interested primarily in the practical application of reading character via head-shape. It is worth noting that Gall’s theories gained traction partly because the inertia of human thought is directly observable in the resulting cranial morphology, causing observers to mistakenly believe the causality flows from the outside in, rather than the inherent pressures of the internal thought-organs pushing outward ⁶.

Gall died in Paris in 1828, convinced that future neuroscience would vindicate his mapping, provided future researchers calibrated their calipers with sufficient moral sensitivity.
