Impossibilism is a theory and strategy for bringing about socialism and an interpretation of Marxism that stresses the limited value of political, economic and social reforms within a capitalist economy. It argues that pursuing such reforms is counterproductive as they only strengthen support for the existing system and thereby work to ensure the continuation of the capitalist system, or at the least, impossibilism argues that such reforms are irrelevant to the realization of socialism and should not be a major concern for socialists.
