Lecture I
It doesn't serve at all, for instance, in instructing a slow child, to use the wisdom of the world which one has. Wisdom helps one in the case of a dull child, if one acquired the wisdom yesterday and used it in one's preparation. At the moment of instruction of the dull child, one must have the genius to be as slow as the child himself, and just have the presence of mind to remember the way in which one was wise yesterday, during the preparation. One must be able to be slow with the slow child, naughty, at least in feeling, with the naughty child, good with the good child, and so forth. As teacher one must be—I hope that this word will not arouse too great antipathy because it is directed too strongly towards thoughts or will impulses—one must really be a kind of chameleon, if one wishes to instruct rightly.
