Specific understanding of socialism - in the same way as he did - is a product of the struggle being waged for it; it can only be achieved in the struggle for socialism, but in the process and the result of this struggle. And any attempt to come to an understanding of socialism is this dialectical interaction with his everyday problems of the class struggle does this understanding of metaphysics, a utopia, something purely contemplative, and not practical.
