Men are living in the midst of a world pervaded by ideas.* Ideas, which provide men with help in their will to act and to think according to rules, which offer them guidance in their lives, are mustered into systems which are called ideologies.Ideologies are issued by the inclusive society, by special, functional groups inside the society and, beginning with a given stage in the development of human society, by ideological movements which profess to provide men not only with guidance (...) for special tasks or functions, but for life as a whole. So, individual men are faced with various sets of ideologies, more or less in agreement between themselves, more 'or less authoritative for them. They must choose between the suggestions, the rules, the orders given to them. As men are always in search of some degree of consistency in their ways of thinking and acting, they fit together the ideas they choose, unconsciously, into systems, into personal, private, individual ideologies.
