Our current political economy does not sufficiently take account of time as an element in trade operations; but as soon as the division of labour has once established itself in a community, two principles at once begin to be important, of which time is the very essence. These are—
First. That as goods are produced to be exchanged, it is good that they should be exchanged as quickly as possible.
Secondly. That as every producer is mainly occupied in producing what others want, and not what he wants himself, it is desirable that he should always be able to find, without effort, without delay, and without uncertainty, others who want what he can produce.
In themselves these principles are self-evident. Every one will admit it to be expedient that all goods wanting to be sold should be sold as soon as they are ready; that every man who wants to work should find employment as soon as he is ready for it. Obviously also, as soon as the "division of labour" is really established, there is a difficulty about both of these principles. A produces what he thinks B wants, but it may be a mistake, and B may not want it. A may be able and willing to produce what B wants, but he may not be able to find B—he may not know of his existence.
The general truth of these principles is obvious,
