As a slight theoretical detour I'm posting this nugget of insight from Rosa Luxemburg:
'Legislative reform and revolution are not different methods of historic development that can be picked out at the pleasure from the counter of history, just as one chooses hot or cold sausages. Legislative reform and revolution are different factors in the development of class society. They condition and complement each other, and are at the same time reciprocally exclusive, as are the north and south poles, the bourgeoisie and proletariat.
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.
It is contrary to history to represent work for reforms as a long-drawn out revolution and revolution as a condensed series of reforms. A social transformation and a legislative reform do not differ according to their duration but according to their content. The secret of historic change through the utilisation of political power resides precisely in the transformation of simple quantitative modification into a new quality, or to speak more concretely, in the passage of an historic period from one given form of society to another.
That is why people who pronounce themselves in favour of the method of legislative reform in place and in contradistinction to the conquest of political power and social revolution, do not really choose a more tranquil, calmer and slower road to the same goal, but a different goal. Instead of taking a stand for the establishment of a new society they take a stand for surface modifications of the old society.
If we follow the political conceptions of revisionism, we arrive at the same conclusion that is reached when we follow the economic theories of revisionism. Our program becomes not the realisation of socialism, but the reform of capitalism; not the suppression of the wage labour system but the diminution of exploitation, that is, the suppression of the abuses of capitalism instead of suppression of capitalism itself.'
