Important early work on mental illness by Thomas Arnold (c.1742-1816), physician to Leicester Infirmary and proprietor of a mental illness facility in the city. The first volume concerns the incidence, definition and arrangement of insanity while the second covers its causes and prevention; Arnold advocated for the humane treatment of patients, with firm management and temperance in all things. Arnold's progressive assessments were at the forefront of the very early embryonic stages of psychiatry in England - "Historically Arnold's importance was that he attempted a new classification of insanity by mental symptoms 'drawn with some care and exactness immediately from nature' rather than by arbitrary social assessment of degree of madness, prevailing affective state, or presence of fever". In this, his major work, Arnold "abandoned the traditional humoral theories, basing his classification on the ideas of Locke and separating disordered sensations from disordered reasoning. He helped to pioneer a new approach to insanity based on observed symptoms, but his classification was too detailed to be practical and it never became popular. Arnold is representative of a shift towards the 'moral' treatment of the insane. Along with Samuel Tuke, he thought that patients should be treated as children rather than as brutes, and advocated that physical restraints should be used only on violent patients. Along with William Battie, he advised that the insane should be segregated from the outside world" ODNB, Hunter & Macalpine: Three Hundred Years of Psychiatry, 1535-1860, pp., 467-71. …
