IB, ID, represent the total product, general utility, what satisfies man’s wants, absolute wealth.

IA, IC, the co-operation of nature, gratuitous utility, the part which belongs to the domain of community.

AB, CD, human service, onerous utility, value, relative wealth, the part which belongs to the domain of property.

I need not say that AB, which you may suppose, if you will, to represent a house, a piece of furniture, a book, a song sung by Jenny Lind, a horse, a bale of cloth, a consultation of physicians, etc., will exchange for twice CD, and that the two men who effect the exchange will give into the bargain, and without even being aware of it, the one, once IA, the other twice IC.

Man is so constituted that his constant endeavour is to diminish the proportion of effort to result, to substitute the action of nature for his own action; in a word, to accomplish more with less. This is the constant aim of his skill, his intelligence, and his energy.

Let us suppose then that John, the producer of IB, discovers a process by means of which he accomplishes his work with one-half the labour which it formerly cost him, taking everything into account, even the construction of the instrument by means of which he avails himself of the co-operation of nature.

As long as he preserves his secret, we shall have no change in the figures we have given above; AB and CD will represent the same values, the same relations; for John alone of all the world being acquainted with the improved process, he will turn it exclusively to his own profit and advantage. He will take his ease for half the day, or else he will make, each day, twice the quantity of IB, and his labour will be better remunerated. The discovery he has made is for the good of mankind, but mankind in this case is represented by one man.

And here let us remark, in passing, how fallacious is the axiom of the English Economists that value comes from labour, if thereby it is intended to represent value and labour as proportionate. Here we have the labour diminished by one-half, and yet no change in the value. This is what constantly happens, and why? Because the service is the same. Before as after the discovery, as long as it is a secret, he who gives or transfers IB renders the same service. But things will no longer be in the same position when Peter, the producer of ID, is enabled to say, “You ask me for two hours of my labour in exchange for one hour of yours; but I have found out your process, and if you set so high a price on your service, I shall serve myself.”

Now this day must necessarily come. A process once realized [p330] is not long a mystery. Then the value of the product IB will fall by one-half, and we shall have these two figures.
