1. Classification of Revolutions.
We generally apply the term revolution to sudden political changes, but the expression may be employed to denote all sudden transformations, or transformations apparently sudden, whether of beliefs, ideas, or doctrines.
We have considered elsewhere the part played by the rational, affective, and mystic factors in the genesis of the opinions and beliefs which determine conduct. We need not therefore return to the subject here.
A revolution may finally become a belief, but it often commences under the action of perfectly rational motives: the suppression of crying abuses, of a detested despotic government, or an unpopular sovereign, &c.
Although the origin of a revolution may be perfectly rational, we must not forget that the reasons invoked in preparing for it do not influence the crowd until they have been transformed into sentiments. Rational logic can point to the abuses to be destroyed, but to move the multitude its hopes must be awakened. This can only be effected by the action of the affective and mystic elements which give man the power to act. At the time of the French Revolution, for example, rational logic, in the hands of the philosophers, demonstrated the inconveniences of the ancien regime, and excited the desire to change it. Mystic logic inspired belief in the virtues of a society created in all its members according to certain principles. Affective logic unchained the passions confined by the bonds of ages and led to the worst excesses. Collective logic ruled the clubs and the Assemblies and impelled their members to actions which neither rational nor affective nor mystic logic would ever have caused them to commit.
