An antinomy is made up of two terms, necessary to each other, but always opposed, and tending to mutual destruction. I hardly dare to add, as I must, that the first of these terms has received the name thesis, position, and the second the name anti-thesis, counter-position. This method of thought is now so well-known that it will soon figure, I hope, in the text-books of the primary schools. We shall see directly how from the combination of these two zeros unity springs forth, or the idea which dispels the antinomy. Thus, in value, there is nothing useful that cannot be exchanged, nothing exchangeable if it be not useful: value in use and value in exchange are inseparable. But while, by industrial progress, demand varies and multiplies to an infinite extent, and while manufactures tend in consequence to increase the natural utility of things, and finally to convert all useful value into exchangeable value, production, on the other hand, continually increasing the power of its instruments and always reducing its expenses, tends to restore the venal value of things to their primitive utility: so that value in use and value in exchange are in perpetual struggle. The effects of this struggle are well-known: the wars of commerce and of the market; obstructions to business; stagnation; prohibition; the massacres of competition; monopoly; reductions of wages; laws fixing maximum prices; the crushing inequality of fortunes; misery,--all these result from the antinomy of value. The proof of this I may be excused from giving here, as it will appear naturally in the chapters to follow. The socialists, while justly demanding that this antagonism be brought to an end, have erred in mistaking its source, and in seeing in it only a mental oversight, capable of rectification by a legal decree. Hence this lamentable outbreak of sentimentalism, which has rendered socialism so insipid to positive minds, and which, spreading the absurdest delusions, makes so many fresh dupes every day. My complaint of socialism is not that it has appeared among us without cause, but that it has clung so long and so obstinately to its silliness.
