Sound Mind Or, Contributions to the natural history and physiology of the human intellect

"Sound Mind" by John Haslam is a scientific exploration that seeks to define a healthy intellect by first understanding its natural functions, such as perception, memory, and reason. Haslam's writing emphasizes that to know when the mind is disordered, we must first deeply understand how it works when it’s healthy; therefore, the book proposes a careful look into the human mind through observation and thoughtful analysis of mental capabilities. This approach sets the stage for comparisons between the normal functions of the intellect and its aberrations, and the book works to establish a clearer and more educated understanding of psychology and psychiatry.
