Peter Drucker, “Knowledge is the Business,” Managing for Results, (London: Pan Books Ltd, 1964), p.132:
Business is a human organization, made or broken by the quality of its people. Labour might one day be done by machines to the point where it is fully automated. But knowledge is a specifically human resource. It is not found in books. Books contain information; whereas knowledge is the ability to apply information to specific work and performance. And that only comes with a human being, his brain or the skill of his hands.
