Hermann Hesse said this quote

“ It is wrong to say that schoolmasters lack heart and are dried-up, soulless pedants! No, by no means. When a child's talent which he has sought to kindle suddenly bursts forth, when the boy puts aside his wooden sword, slingshot, bow-and-arrow and other childish games, when he begins to forge ahead, when the seriousness of the work begins to transform the rough-neck into a delicate, serious and an almost ascetic creature, when his face takes on an intelligent, deeper and more purposeful expression - then a teacher's heart laughs with happiness and pride. It is his duty and responsibility to control the raw energies and desires of his charges and replace them with calmer, more moderate ideals. What would many happy citizens and trustworthy officials have become but unruly, stormy innovators and dreamers of useless dreams, if not for the effort of their schools? In young beings there is something wild, ungovernable, uncultured which first has to be tamed. It is like a dangerous flame that has to be controlled or it will destroy. Natural man is unpredictable, opaque, dangerous, like a torrent cascading out of uncharted mountains. At the start, his soul is a jungle without paths or order. And, like a jungle, it must first be cleared and its growth thwarted. Thus it is the school's task to subdue and control man with force and make him a useful member of society, to kindle those qualities in him whose development will bring him to triumphant completion. ”
