Good teaching is forever being on the cutting edge of a child's competence.
Teaching is the canny art of intellectual temptation
The young child approaching a new subject or anew problem is like the scientist operating at the edge of his chosen field.
It is sentimentalism to assume that the teaching of life can always be fitted to the child's interests, just as it is empty formalism to force the child to parrot the formulas of adult society. Interests can be created and stimulated.
We carry with us habits of thought and taste fostered in some nearly forgotten classroom by a certain teacher.
