Adam Smith's Wealth of Nations

The general advantages which Europe, considered as one great country, has derived from the discovery and colonization of America, consist, first, in the increase of its enjoyments; and, secondly, in the augmentation of its industry.

The surplus produce of America, imported into Europe, furnishes the inbabitants of this great continent with a variety of commodities which they could not Otherwise have possessed, some for conveniency and use, some for pleasure, and some for ornament, and thereby contributes to increase their enjoyments.

The discovery and colonization of America, it will readily be allowed, have contributed to augment the in dustry, first, of all the countries which trade to it directly; such as Spain, Portugal, France, and England; and, secondly, of all those which, without trading to it directly, send, through the medium of other countries, goods to it of their own produce; such as Austrian Flanders, and some provinces of Germany, which, through the medium of the countries before mentioned, send to it a considerable quantity of linen and other goods. All such countries have evidently gained a more extensive market for their surplus produce, and must tonsequently have been encouraged to increase its quantity.
