As would be the case

for Kraepelin later, many cases that captured the interest of both Esquirol and Prichard had forensic consequences. This shows that the practical question was whether psychiatry could explain patterns of abnormal behavior, in subjects with a normal intellect and no acute psychiatric symptoms who had come into contact with the law. The period between the late 19th century and early 20th century was marked by the emergence of several elaborate systems of normal and abnormal personality, associating to Inhibitors,research,lifescience,medical some degree types and dimensions. A succession of European psychologists, such as Ribot, Heymans, and Lazursky, deserve mention. Theodule Ribot (1839-1916), a French psychologist known for coining the term “Anhedonia,” wrote on normal and abnormal characters.11 Ribot’s treatise was translated into English within a year (the Psychology of Emotions, 1897), and English-speaking contemporaries were familiar with his ideas. Like his predecessors, Ribot stressed that character is stable, appearing in childhood and lasting all life. Ribot’s Inhibitors,research,lifescience,medical classification had ”subtypes,“ defined by the association of several ”primary types.“ Ribot’s terminology

is antiquated, but Inhibitors,research,lifescience,medical his system becomes more limpid when one realizes that he is, in fact, describing dimensions. Normal personality was characterized by the three following primary types: (i) the sensitive or emotional, whose nervous system was easily impressed by pleasant or unpleasant emotions, and whose feelings were introverted; (ii) the active, who were extraverted, spontaneous, and courageous; (iii) and the apathetic, corresponding to the lymphatic of the humoral classification, who displayed little Inhibitors,research,lifescience,medical propensity to excitation and reaction. These three primary categories were further subdivided into various ”subtypes,“ according to the association of several dimensions. For instance, the sensitive were subdivided into: the (i) humble, with limited

intelligence and energy; (ii) the contemplative, who showed sensitivity, a keen intellect, and little activity Inhibitors,research,lifescience,medical (Hamlet, indecisive, was given as an example); and (iii) the emotional, stricto sensu. Among the active, the association of high activity, high intelligence, and little sensitivity Cytidine deaminase could produce historical figures such as empire builders (Ribot mentioned Hernan Cortez and Pizarro). Subjects associating apathy with intelligence were good at strategy and uncheck details emotional reasoning (eg, Benjamin Franklin, or Philip II of Spain). It is noteworthy that intelligence was an important modifier of personality according to Ribot; later authors would also stress this. Gerard Heymans (1857-1930) was a professor of philosophy and psychology at the University of Groningen (in the Netherlands). He coauthored articles with Enno Dirk Wiersma (1858-1940), a professor of psychiatry at the same university.
