“Capital signifies "head, or source, or root material" – it is material by which some derivative or secondary good is produced. It is only capital proper (caput vivum, not caput mortuum) when it is thus producing something different from itself. It is a root, which does not enter into vital function till it produces something else than a root: namely, fruit. That fruit will in time again produce roots; and so all living capital issues in reproduction of capital; but capital which produces nothing but capital is only root producing root; bulb issuing in bulb, never in tulip; seed issuing in seed, never in bread. The Political Economy of Europe has hitherto devoted itself wholly to the multiplication, or (less even) the aggregation, of bulbs. It never saw, nor conceived, such a thing as a tulip.”
