The broad outlines of this study can be summed up in three main points. On the one hand we have endeavored to show that mobilizing ideologies are structurally determined. They are at once the expression of modes of dependence and of the structure of social relations specific to each social formation. As a result the configuration they take on is the product of particular alliances between social classes.On the other hand while integrative populism was a prime example of what might be called an ideology-brake given its alienating effects reformist populism was more a case of an ideology-motor.Finally and this is our third point we have tried to highlight the existence of a characteristic link between the level of consciousness and the ascending or descending aspect of the mobilization process.
