The Wealth of Nature | MetaFilter

“Schumacher drew a hard distinction between primary goods and secondary goods. The latter of these includes everything dealt with by conventional economics: the goods and services produced by human labor and exchanged among human beings. The former includes all those things necessary for human life and economic activity that are produced not by human beings, but by nature. Schumacher pointed out that primary goods, as the phrase implies, need to come first in any economic analysis because they supply the preconditions for the production of secondary goods.”
