"The Revolt of the Masses" is a philosophical work that discusses the rise of the "mass man" and the potential danger this presents to society. The author argues that the mass man, characterized by his lack of individuality and rejection of higher values, is a product of modern society and its emphasis on equality. He believes that this mass man, who is more concerned with his rights than his responsibilities, threatens to undermine the very foundations of society, leading to potential chaos and instability. The book serves as a warning and a call for a return to individual responsibility and respect for higher values.

"Scepticism and Animal Faith" is a philosophical work that presents the idea that knowledge is not found through evidence or reason, but through animal faith, a term referring to instinctive beliefs. The book delves into the nature of perception and consciousness, and argues that all human knowledge is grounded in unproven preconceptions. The author suggests that to understand the world, humans must first acknowledge their own preconceived notions and biases, and then attempt to understand the world through a lens of skepticism.
