ABSTRACT
Two uses of knowledge are pre-eminent in importance, though unequally recognized in different times and places and in different societies. One is using knowledge to gain more knowledge; the other is using knowledge not only to pass knowledge on but to spread it more widely. The arts of inquiry transform the practical life into means, with new knowledge as the end. The laboratory has indeed been extended to include the garden, the seashore and mountainside, the studio, and the library; but in some ways the Archimedean component remains central. The laboratory was a mirror of the practical Hellenistic life of trade and manufacturing. The chapter describes the educative process in its full breadth and power, as involving all the means of culture transmission and cultural innovation, including all its relevant material and human ambience. It presents a diagnosis of educational pathology while examining the nature and difficulty of the cure.
