Summary & Review

The human mind is a battleground between intellectual components and instinctive drives. In certain situations, instinctive forces take over, leading individuals to form groups, masses, and mobs, where the "herd instinct" dominates. This can result in either significant benefits or irreparable harm to society. Delusions, which are rigid and lack self-correction, can originate from within ourselves or come as suggestions from outside. When thinking becomes detached from feelings, it can lead to obscure depths. Mass delusions have been a part of human history and can threaten more mature forms of mental life. However, they can also lead to new defenses and changes in physical and mental structures.
