As a teacher, one has a variety of individualities before one, and one should not stand in front of the class with the feeling: The way I am, is the way these pupils should all become through my teaching and education. This is how one should absolutely not feel. Why not? Now there could be, if we are lucky, among the students that we have in our class, apart from those who are not very clever, two or three who may be exceptionally talented. And you will have to admit that it is not possible to have only geniuses for teachers and that in fact it will not infrequently occur that the teacher does not have the capacities that those they are teaching and educating will perhaps develop in the future. But the teacher does not only need to teach those who have the same capacities as he has himself, he must also educate and teach those who are far more talented and would surpass him in time. However, he will only be able to do this if he does not try to educate the pupils as if they should become similar to what he is himself.
