In this seminal work, Freud describes psychological mechanisms at work within mass movements. A mass, according to Freud, is a "temporary entity, consisting of heterogeneous elements that have joined together for a moment." Like Gustav Le Bon, Freud says that as part of the mass, the individual acquires a sense of infinite power which allows him to act on impulses that he would otherwise have to curb as an isolated individual.
Sigmund Freud was an Austrian neurologist and the founder of psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and a psychoanalyst.
