Joenes’s students quickly absorbed the material given to them, passed their tests, and quickly forgot the material. Like many vital young organisms, they were able to eject anything harmful, disturbing, distressing, or merely boring. Of course they also ejected anything useful, stimulating, or thought provoking. This was perhaps regrettable, but it was part of the educative process to which every teacher had to accustom himself.
