H A P T E R XiV ELEVATION SILENCE: ABSTRACTIONS MATERIALIZED ONE of the differences between our method and those generally used in the schools for the education of normal children bears reference to the way of education. Perhaps the * silence' may serve to illustrate the idea. In the ordinary schools there is discussed a state of normal order which is accepted although it has never been defined. It is that state in which the behaviour of the class makes it possible for the master to give a lesson. As, however, the class is acting under compulsion the tendency is to drift from that mediocre state of order into a disorder in which movements of all kinds, unco-ordinated and purposeless, create noise and restlessness which make the giving of a lesson difficult or impossible; that is, it disturbs the working order. There must in such a case be an energetic call for 4 silence * indicating with this very word the working order. So the * medium order' is not only something already attain- ed, but is normal and customary; a simple command suffices to obtain it.
