Knowledge Integration in Mechanical Production

Part of the goods which are annually produced, and which are called wealth, is, strictly speaking, waste, because it consists of articles which ... either should not have been produced until other articles had already been produced in sufficient abundance, or should not have been produced at all. And some part of the population is employed in making goods which no man can make with happiness, or indeed without loss of self-respect, because he knows that they had much better not be made; and that his life is wasted in making them.

Production for sale in a market in which the object is to realize the maximum profit is the essential feature of a capitalist world-economy. In such a system production is constantly expanded as long as further production is profitable, and men constantly innovate new ways of producing things that will expand the profit margin.

Various attempts have been made in recent years to state necessary and sufficient conditions for someone's knowing a given proposition. The attempts have often been such that they can be stated in a form similar to the following:
(a) S knows that P IFF (i) P is true, (ii) S believes that P, and (iii) S is justified in believing that P.
... These ... examples show that definition (a) does not state a sufficient condition for someone's knowing a given proposition.
