This book argues that the expression of emotions in humans and animals shares common origins and principles, based on observations rather than abstract theories of character recognition. Darwin distinguishes his work from the study of physiognomy, which focuses on permanent facial features to infer character. His research draws on older treatises and acknowledges the historical contributions of works like Le Brun's "Conferences," but primarily emphasizes direct observation of emotional displays.
The central contribution is Darwin's systematic examination of how emotions are physically manifested across species. Readers gain an understanding of specific observable behaviors associated with emotions, supported by comparative analysis. The focus is on the outward expression of feelings as a biological phenomenon, distinct from attempts to read inherent character traits from static features.
Key concepts
- Expression of Emotions — The physical manifestations of feelings in humans and animals.

From the book
Description: Many works have been written on Expression, but a greater number on Physiognomy, - that is, on the recognition of character through the study of the permanent form of the features. With this latter subject I am not here concerned. The older treatises,[1] which I have consulted, have been of little or no service to me. The famous `Conferences'[2] of the painter Le Brun, published in 1667, is the best known ancient work, and contains some good remarks.
