Man and Woman: Human Secondary Sexual Characters

A groundbreaking study of the biological, psychological, and social differences between the sexes. Combining scientific observation with cultural insight, Ellis examines how physiology, emotion, intellect, and behavior vary between men and women—not as measures of superiority or inferiority, but as reflections of complementary forces within human nature.

Drawing upon anthropology, anatomy, psychology, and art, Ellis explores the development of sexual dimorphism, the influence of heredity and environment, and the expression of gender through body and mind. His work stands as one of the earliest attempts to unite the study of sex, science, and society, challenging Victorian taboos while seeking truth through evidence and empathy.

A seminal text in the history of sexual science and gender studies, Man and Woman remains a cornerstone for understanding how ideas of sex and identity evolved at the dawn of modern psychology.
