A Teacher (n.) is, in the right sense, a learner, a fellow student.
A Teacher (n.) who is human says, when the pupil learns nothing, "it was not my fault"; the lilies and birds, when you learn everything, act as if it were not theirs.
A Teacher (n.) need not have a doctrine: Job taught mankind by what he did, leaving himself as the pattern rather than a saying.
The Teacher (n.) worth the name is a learner: instruction begins when he learns from the one he teaches.
A Teacher (n.) anxious about his pupils' judgement cannot move hand or foot — he dare not even pretend not to understand, lest they believe it; he aspires to be commended by his pupils.
