"One of the most important questions regarding political parties is their “opportuneness” or right-ness for the times”; that is to say, the question of how they react against “habitude” and the tendency to become mummified and anachronistic. In practical terms, political parties come into existence [as organisations] in the wake of historical events that are important for the social groups they represent, but they do not always know how to adapt to new epochs or historical phases, or they are unable to develop in accordance with the ensemble of the relations of forces [and therefore with congruousm forces] in their particular country or in the international sphere. In this analysis, one must make distinctions: the social group; the mass of the party; the bureaucracy of general staff of the party. The latter is the most dangerous in terms of habitude: if it organises itself as a separate body, compact and independent, the party will end up being anachronistic. This is what brings about the crises of parties that suddenly lose their historical social base and find the ground taken from under their feet."
