The successful teacher is no longer on a height, pumping knowledge at high pressure into passive receptacles.

No human being is constituted to know the truth, the whole truth and nothing but the truth; and even the best of men must be content with fragments, with partial glimpses, never the full fruition

There is no height,

Perhaps no sin so easily besets us as a sense of self-satisfied superiority to others.

There are no straight backs, no symmetrical faces, many wry noses, and no even legs. We are a crooked and perverse generation.

No dreams, no visions, no delicious fantasies, no castles in the air, with which, as the old song so truly says, "hearts are broken, heads are turned".
