the duty of the progressive educator

To challenge educands with regard to their certitudes is a duty of the progressive educator. What kind of educator would I be if I did not feel moved by a powerful impulse to seek, without lying, convincing arguments in defense of the dreams for which I struggle, in defence of the 'why' of the hope with which I act as an educator?
What is not permissible to be doing is to conceal truths, deny information, impose principles, eviscerate the educands of their freedom, or punish them, no matter by what method, if, for various reasons, they fail to accepts my discourse - reject my utopia.
