No More Learning

The
ironical man           to be ignorant, and does it
so well that the pupils conversing with him are
deceived, and in their firm belief in their own
superior knowledge they grow bold and expose all
their weak points; they lose their cautiousness and
reveal themselves as they are,—until all of a sudden
the light which they have held up to the teacher's
face casts its rays back very humiliatingly upon
themselves.
