"Sometimes one sees in the school simply the instrument for transferring a certain maximum quantity of knowledge to the growing generation. But that is not right. Knowledge is dead; the school, however serves the living. It should develop in the young individual those qualities and capabilities which are of value for the welfare of the commonwealth. But that does not mean that individuality should be destroyed and the individual becomes a mere tool of the community, like a bee or an ant. For a community of standardized individuals without personal originality and personal aims would be a poor community without possibilities for development. On the contrary, the aim must be the training of independently acting and thinking individuals, who, however, see in the service of the community, their highest life problem."
"But how shall one try to attain this ideal? Should one perhaps try to realize this aim by moralizing? Not at all. Words are and remain an empty sound and the road to perdition has ever been accomplished by lip service to an ideal. But personalities are not formed by what is heard and said but by labor and activity."
--Albert Einstein, 1936
@Melba also i find the lip service to an ideal part significant because people often use "thinking outside the box" too as an empty sound and not as a committment to labour and activity.
