Nor is this the only changeable element in modern industrial societies. Credit--the disposition of one man to trust another--is singularly varying. In England, after a great calamity, everybody is suspicious of everybody; as soon as that calamity is forgotten, everybody again confides in everybody. On the Continent there has been a stiff controversy as to whether credit should or should not be called capital:' in England, even the little attention once paid to abstract economics is now diverted, and no one cares in the least for refined questions of this kind: the material practical point is that, in M. Chevalier's language, credit is 'additive,' or additional--that is, in times when credit is good productive power is more efficient, and in times when credit is bad productive power is less efficient. And the state of credit is thus influential, because of the two principles which have just been explained. In a good state of credit, goods lie on hand a much less time than when credit is bad; sales are quicker; intermediate dealers borrow easily to augment their trade, and so more and more goods are more quickly and more easily transmitted from the producer to the consumer. These two variable causes are causes of real prosperity. They augment trade and production, and so are plainly beneficial, except where by mistake the wrong things are produced, or where also by mistake misplaced credit is given, and a man who cannot produce anything which is wanted gets the produce of other people's labour upon a false idea that he will produce it. But there is another variable cause which produces far more of apparent than of real prosperity and of which the effect is in actual life mostly confused with those of the others.
