The book is devoted to the study of such concepts as “crowd”, “masses” and their role in the process of historical development. It is shown that social philosophy throughout its history has been engaged not only in the study of problems of the individual, but also of these subjects of the historical process... We are talking about the behavior of the masses and the factors that determine this behavior. The author's approach is associated with the revelation that the nature of social conflicts is not limited to the presence in society of various material interests of certain groups and strata, but is also determined by the behavior of the masses, which is very important influenced by numerous irrational factors. The book is addressed to specialists in the field of the history of philosophy, history of political doctrines, politicians and political scientists, as well as everyone interested in the problems of the relationship between social philosophy and politics.
