Implanting standards, right values, the science of good and evil are an essential part of education. Many forces thwart this to work, but two of the most serious hindrances to it are examinations and specialization. The examination system is both an opiate and a poison. It is an opiate because it lulls Man into believing that all is well when most is ill. It is a poison because it paralyses or at least slows down the natural activities of the healthy mind. Man finds himself a creature of unknown capacities in an unknown world, wants to learn what the world is like, what he should be and do in it. To help him in answering these questions is the one and only purpose of education. However, tests of progress are useful and necessary. Examinations are harmless when the examinee is indifferent to their result, but as soon as they matter, they begin to distort his attitude to education and to conceal its purpose. For disinterestedness is the essence of all good education and liberal education is impossible without it. The purpose of education is
