"Every legal constitution is the product of a revolution. In the history of classes, revolution is the act of political creation, while legislation is the political expression of the life of a society that has already come into being. Work for reform does not contain its own force independent from revolution. During every historic period, work for reforms is carried on only in the direction given to it by the impetus of the last revolution and continues as long as the impulsion from the last revolution continues to make itself felt. Or, to put it more concretely, in each historic period work for reforms is carried on only in the framework of the social form created by the last revolution. Here is the kernel of the problem."
