labor power is now in the market on the same footing as any other ware exposed there for sale. EXCHANGE VALUE. It is evident that the custom of exchange will arise in the first instance as soon as men give up providing each for his own needs by his own labor. A man who makes his own tables and chairs, his own poker and kettle, his own bread and butter, and his own house and clothes, is jack-of-all-trades and master of none. He finds that he would get on much faster if he stuck to making tables and chairs, and exchanged them with the smith for a poker and kettle, with bakers and dairymen for bread and butter, and with builders and tailors for a house and clothes. In doing this, he finds that his tables and chairs are worth so much--that they have an exchange value, as it is called. As a matter of general convenience, some suitable commodity is set up to measure this value. We set up gold, which in this particular use of it, is called money. The chairmaker finds how much money his chairs are worth, and exchanges them for it. The blacksmith finds out how much money his pokers are worth, and exchanges them for it. Thus, by employing money as a go-between, chairmakers can get pokers in exchange for their chairs, and blacksmiths chairs for their pokers. This is the mechanism of exchange; and once the values of the commodities are ascertained it works simply enough. But it is a mere mechanism, and does not fix the values or explain them. And the attempt to discover what does fix them is beset with apparent contradictions which block up the right path, and with seductive coincidences which make the wrong seem the more promising.
