Exchange is so important a process in the maximising of utility and the saving of labour, that some ecomists have regarded their science as treating of this operation alone. Utility arises from commodities being brought in suitable quantities and at the proper times into the possession of persons needing them; and it is by exchange, more than any other means, that this is effected. Trade is t indeed the only method of ecomising: a single individual may gain in utility by a proper consumption of the stock in his possession. The best employment of labour and capital by a single person is also a question disconnected from that of exchange, and which must yet be treated in the science. But, with these exceptions, I am perfectly willing to agree with the high importance attributed to exchange. It is impossible to have a correct idea of the science of Ecomics without a perfect comprehension of the Theory of Exchange; and I find it both possible and desirable to consider this subject before introducing any tions concerning labour or the production of commodities. In these words of J. S. Mill I thoroughly concur: Almost every speculation respecting the ecomical interests of a society thus constituted, implies some theory of Value: the smallest error on that subject infects with corresponding error all our other conclusions; and anything vague or misty in our conception of it creates confusion and uncertainty in everything else. But when he proceeds to say, Happily, there is thing in the laws of Value which remains for the present or any future writer to clear up; the theory of the subject is complete 1--he utters that which it would be rash to say of any of the...
