The characteristics of the reasoning of crowds are the association of dissimilar things possessing a merely apparent connection between each other, and the immediate generalisation of particular cases. It is arguments of this kind that are always presented to crowds by those who know how to manage them.They are the only arguments by which crowds are to be influenced. A chain of logical argumentation is totally incomprehensible to crowds, and for this reason it is permissible to say that they do not reason or that they reason falsely and are not to be infiuenced by reasoning. Astonishment is felt at times on reading certain speeches at their weakness, and yet they had an enormous influence on the crowds which listened to them, but it is forgotten that they were intended to persuade collectivities and not to be read by philosophers. An orator in intimate communication with a crowd can evoke images by which it will be seduced. If he is successful his object has been attained, and twenty volumes of harangues—always the outcome of reflection—are not worth the few phrases which appealed to the brains it was required to convince.
