Teaching is an incarnation of ideas. Most people cannot define such things as loyalty and patriotism. They can, however, point to someone who has these qualities. It is easier to learn loyalty from a loyal person than from a lecture on loyalty. Hence, the right teacher would incorporate these ideals and others into his personality and character so that the pupil can emulate him and reach the desired end.
Teaching is the ability to inspire learning.
Good teaching makes learning easy and, to some degree, fun. Again, this puts not only the burden of teaching on the teacher but also the burden of learning and places the responsibility of failur e on the teacher's shoulders as well as the student's.
