In 1500 Erasmus wrote a friend these lines:
My Greek studies are almost too much for my courage; while I have not the means of purchasing books, or the help of a teacher. And while I am in all this trouble, I have scarcely the wherewithal to sustain life; so much is our learning worth to us!
Erasmus valued learning and teaching above eating. Most of our contemporaries value eating more, so that while they are happy to spend $60 on a dinner out they cringe at the thought of spending that much on a great book.
We live in strange times.
