““It needs to be borne in mind that there are always, and inevitably, two sides to the revolutionary coin. The first is negative and destructive, and leads to the drive to undermine the beliefs, values and institutions of the old order, which must be destroyed before a new one can be created. The second component of the revolutionary vision is positive and utopian—the image of a future that condemns the present and encapsulates the idea of a redemptive fate.””
