In this respect, of course, Tugan Baranovski goes even farther. With his love of paradox he actually permits himself the joke of submitting a mathematical proof that accumulation of capital and expansion of production are possible even if the absolute volume of production decreases. In this connection, Karl Kautsky has pointed out, he had recourse to a somewhat dubious scientific subterfuge, namely that he shaped his daring deductions exclusively for a specific moment: the transition from simple to enlarged reproduction--a moment which is exceptional even in theory, but certainly of no practical significance whatever.[327] As to Tugan Baranovski's 'fundamental law', Kautsky declares it to be a mere illusion due to the fact that Tugan Baranovski considered the organisation of production only in the old countries of capitalist big industry. 'It is correct', Kautsky says, 'that with a progressive division of labour, there will be comparatively fewer and fewer factories etc. for the production of goods direct for personal consumption, together with a relative increase in the number of those which supply both the former and one another with tools, machines, raw materials, transport facilities and so on. While in original peasant economy an enterprise that cultivated the flax also made the linen with its own tools and got it ready for human consumption, nowadays hundreds of enterprises may share in the manufacture of a single shirt, by producing raw cotton, iron rails, steam engines and railway trucks that bring it to port, and so on. With international division of labour it will happen that some countries--the old industrial countries--can only slowly expand their production for personal consumption, while making large strides in their production of producer goods which is much more decisive for the heartbeat of economic life than the production of consumer goods. From the point of view of the nation concerned, we might easily form the opinion that producer goods can be turned out on a constantly rising scale with a more rapid rate of increase than in the production of consumer goods, and that their production is not bound up with that of the latter.' The opinion, that producer goods can be produced independent of consumption, is of course a mirage of Tugan Baranovski's, typical of vulgar economics. Not so the fact cited in support of this fallacy: the quicker growth of Department I as compared with Department II is beyond dispute, not only in old industrial countries but wherever technical progress plays a decisive part in production. It is the foundation also of Marx's fundamental law that the rate of profit tends to fall. Yet in spite of it all, or rather precisely for this reason, it is a howler if Bulgakov, Ilyin and Tugan Baranovski imagine to have discovered in this law the essential nature of capitalist economy as an economic system in which production is an end in itself and human consumption merely incidental.
