Went into school today & found the book order had arrived. I rooted around in the boxes & was pleasantly surprised to discover this item had been included after all. Not strictly a 'set text' but it will permeate the discussions during the coming months.
The very fly leaf tunes into the right frequency - two quotations:
"To affect the quality of the day, that is the highest of the arts." (Thoreau)
"I can't understand why people are frightened of new ideas. I'm frightened of the old ones." (Cage)
Once again a book arrives exactly when I need it.
