In his well-known work on the psychology of the crowd Le Bon noted the fact that the unconscious plays a large part in determining the behavior of crowds. But he is not clear in his use of the term "unconscious." In fact, as Graham Wallas justly points out, his terminology is very loose indeed. Le Bon seems to have made little or no attempt to discover in detail the processes of this unconscious. In company with most psychologists of his time, he based his explanation upon the theory of "suggestion and imitation." He saw in the unconscious merely a sort of mystical "common humanity," from which he derived his—also mystical—idea of a common crowd-mind which each individual in the crowd in some unexplained manner shared. He says:

The most striking peculiarity presented by a psychological crowd is the following: Whoever be the individuals that compose it, however like or unlike be their mode of life, their occupations, their character or their intelligence, the fact that they have been transformed into a crowd puts them in possession of a sort of collective mind which makes them feel, think, and act in a manner quite different from that in which each individual of them would feel, think, and act were he in a state of isolation....

It is easy to prove how much the individual forming part of a crowd differs from the isolated individual, but it is less easy to discover the causes of this difference.

To obtain, at any rate, a glimpse of them it is necessary in the first place to call to mind the truth established by modern psychology, that unconscious phenomena play an altogether preponderating part, not only in organic life, but also in the operations of intelligence.... Our conscious acts are the outcome of an unconscious substratum created in the mind in the main by heredity. This substratum consists of innumerable characteristics handed down from generation to generation which constitute the genius of the race....

It is more especially with respect to those unconscious elements which constitute the genius of a race that all the individuals belonging to it resemble each other.... It is precisely these general qualities of character, governed by forces of which we are unconscious and possessed by the majority of normal individuals of a race in much the same degree—it is precisely these qualities, I say, that in crowds become common property. In the collective mind the intellectual aptitudes of the individuals, and in consequence their individuality, are weakened. The heterogeneous is swamped in the homogeneous and the unconscious qualities obtain the upper hand.

It may safely be said, I think, that this assumed impersonal collective mind of the crowd has no existence in a sound psychology. Peoples minds show, of course, innumerable mutual influences, but they do not fuse and run together. They are in many respects very similar, but similarity is not identity, even when people are crowded together. Our author has doubtless borrowed here rather uncritically from Herbert Spencers organic conception of society—his later statement, not quoted here, that the alleged merging of the heterogeneous in the homogeneous would logically imply a regression to a lower stage in evolution, is another bit of Spencerian jargon commonly accepted in Le Bons day.

When, however, Graham Wallas, in The Great Society, states that Le Bon is not "himself clear whether he means that crowds have no collective consciousness, or that every individual in a crowd is completely unconscious," it seems to me that Wallas is a little unfair. Neither Le Bon nor the relation of the unconscious to the crowd-mind may be dismissed in Wallass apparently easy manner. Le Bon has established two points which I think cannot be successfully denied: first, that the crowd is essentially a psychological phenomenon, people behaving differently in a crowd from the way they behave when isolated; and second, that the unconscious has something to do with crowd-thinking and acting.

Wallas says of Le Bon:

Tarde and Le Bon were Frenchmen brought up on vivid descriptions of the Revolution and themselves apprehensive of the spread of socialism. Political movements which were in large part carried out by men conscious and thoughtful, though necessarily ill informed, seemed therefore to them as they watched them from the outside to be due to the blind and unconscious impulses of masses "incapable both of reflection and of reasoning."

There is some truth in this criticism. In spite of the attempt of the famous author of crowd-psychology to give us a really scientific explanation of crowd-phenomena, his obviously conservative bias robs his work of much of its power to convince. We find here, just as in the case of Gobineau, Nietzsche, Faguet, Conway, and other supporters of the aristocratic idea, an a priori principle of distrust of the common people as such. In many passages Le Bon does not sufficiently distinguish between the crowd and the masses. Class and mass are opposed to each other as though, due to their superior reasoning powers, the classes were somehow free from the danger of behaving as crowd. This is of course not true. Any class may behave and think as a crowd—in fact it usually does so in so far as its class interests are concerned. Anyone who makes a study of the public mind in America to-day will find that the phenomena of the crowd-mind are not at all confined to movements within the working class or so-called common people.

It has long been the habit of conservative writers to identify the crowd with the proletariat and then to feel that the psychology of the situation could be summed up in the statement that the crowd was simply the creature of passion and blind emotion. The psychology which lies back of such a view—if it is psychology rather than class prejudice—is the old intellectualism which sought to isolate the intellect from the emotional nature and make the true mental life primarily a knowledge affair. The crowd, therefore, since it was regarded as an affair of the emotions, was held to be one among many instances of the natural mental inferiority of the common people, and a proof of their general unfitness for self-government.

I do not believe that this emotional theory is the true explanation of crowd-behavior. It cannot be denied that people in a crowd become strangely excited. But it is not only in crowds that people show emotion. Feeling, instinct, impulse, are the dynamic of all mental life. The crowd doubtless inhibits as many emotions as it releases. Fear is conspicuously absent in battle, pity in a lynching mob. Crowds are notoriously anæsthetic toward the finer values of art, music, and poetry. It may even be argued that the feelings of the crowd are dulled, since it is only the exaggerated, the obvious, the cheaply sentimental, which easily moves it.
