Johann Friedrich Herbart learned being tactful. That is to say that he asked high difficulties to those whom could, that he asked beginning difficulties to those whom hesitated. Indeed, at the beginning we have few borders but very limited borders. Then we have extensive boundaries, and, at the end, we search beyond our limits.
The tact and the joy is thus to read to the one whom is in front of you, to bring him his truth, his happiness, when he will not be there any more.
So, we are all searching for the truth. Indeed, this kind of approach brings joy virally, because those whom hear this pedagogical approach and are aware to the liberal society, whose they live, understand that it is up to everyone to grow finding happiness.
