Here are some of his notable works:
* "The Savage Hits Back" (1937): This book is a scathing critique of Western colonialism and its impact on indigenous peoples. It examines how European civilization has often exploited and denigrated non-Western cultures, arguing that the "primitive" are not inherently inferior.
* "The Development of the Primitive" (1937): This work explores the evolution of human societies and cultures, focusing on the diverse forms of social organization and cultural practices found in non-Western societies.
* "The Origin and Development of the Primitive Mind" (1930): This book examines the psychological and cognitive differences between "primitive" and "civilized" societies, arguing that there are significant variations in human thinking and behavior that are shaped by cultural influences.
* "The Psychology of Primitive Peoples" (1929): This book explores the psychological characteristics of indigenous cultures, examining concepts such as perception, memory, and language.
* "The German Colonies" (1920): A study of the social and cultural landscapes of German colonial possessions in Africa and Oceania.
In addition to these major works, Lips also published numerous articles and essays on anthropological topics, including:
* "The Social Structure of Primitive Societies"
* "The Role of Religion in Primitive Cultures"
* "The Art and Music of Primitive Peoples"
Lips' work was often controversial due to its critical stance on colonialism and its emphasis on the value and diversity of non-Western cultures. Despite facing criticism and suppression by the Nazi regime, his writings continue to be influential in the field of anthropology.
