The Crowd: A Study of the Popular Mind (French: Psychologie des Foules; literally: Psychology of Crowds) is a book authored by Gustave Le Bon that was first published in 1895.
In the book, Le Bon claims that there are several characteristics of crowd psychology: "impulsiveness, irritability, incapacity to reason, the absence of judgement of the critical spirit, the exaggeration of sentiments, and others..." Le Bon claimed that "an individual immersed for some length of time in a crowd soon finds himself – either in consequence of magnetic influence given out by the crowd or from some other cause of which we are ignorant – in a special state, which much resembles the state of fascination in which the hypnotized individual finds himself in the hands of the hypnotizer."
Environment, circumstances, and events represent the social suggestions of the moment. They may have a considerable influence, but this influence is always momentary if it be contrary to the suggestions of the race; that is, to those which are inherited by a nation from the entire series of its ancestors…The biological sciences have been transformed since embryology has shown the immense influence of the past on the evolution of living beings; and the historical sciences will not undergo a less change when this conception has become more widespread. As yet it is not sufficiently general, and many statesmen are still no further advanced than the theorists of the last century, who believed that a society could break off with its past and be entirely recast on lines suggested solely by the light of reason.
A nation does not choose its institutions at will any more than it chooses the colour of its hair or its eyes. Institutions and governments are the product of the race. They are not the creators of an epoch, but are created by it. Peoples are not governed in accordance with their caprices of the moment, but as their character determines that they shall be governed. Centuries are required to form a political system and centuries needed to change it. Institutions have no intrinsic virtue: in themselves they are neither good nor bad. Those which are good at a given moment for a given people may be harmful in the extreme for another nation.
