Passage:
The origin and progress and future promotion of civilization are all ill understood and misconceived. These should be made the chief theme of education. but much hard work is necessary before we can reconstruct ourideas of man and his capacities and free ourselves from innumerable persistent musapprehensions. There have been obstructionists in all times. not merely the lethargic masses, but the moralists. the rationalizing theologians, and mostof the philosophers, all busily if unconsciously engaged in ratifying existing ignorance and mistakes and discouraging creative thought. Naturally. those who reassure us seem worthy of honour and respect. Equally naturally those who puzzle us with disturbing criticisms and invite us to change our ways are objects of suspicion and readily discredited. Our personal discontent does not ordinarily extend to any critical questioning of the general situation in which we find ourselves. In every age prevailing conditions of civilization have appeared quite natural and inevitable to those who grew up in them. Indeed, we are usually quite unaware that a gameis being playedat all.
