7. The Key Points of the Social Question

From all this we see that there is actually a threefold social question: the proletarian demands, as they arise as world-historical demands in this period, they show a threefold character, as I have stated. One is based on the spiritual, on the spiritual ground; the second is on the legal ground, the third is on the economic ground. Of the spiritual goods, the proletarian only recognizes that which he must provide as his basis, the added value. On the ground of the state, he sees himself only in the class struggle. And on the ground of economic life, he sees himself harnessed into the cycle of economic life, so that not only goods circulate in it, but also his own labor, that is, his flesh and blood.
