" The economic principles of Modern Socialism are a logical deduction from the principle laid down by Adam Smith in the early chapters of his "Wealth of Nations,"—namely, that labor is the true measure of price. But Adam Smith, after stating this principle most clearly and concisely, immediately abandoned all further consideration of it to devote himself to showing what actually does measure price, and how, therefore, wealth is at present distributed. Since his day nearly all the political economists have followed his example by confining their function to the description of society as it is, in its industrial and commercial phases. Socialism, on the contrary, extends its function to the description of society as it should be, and the discovery of the means of making it what it should be. Half a century or more after Smith enunciated the principle above stated, Socialism picked it up where he had dropped it, and, in following it to its logical conclusions, made it the basis of a new economic philosophy.
