"The true end of education is not only to make the young learned, but to make them love learning; not only to make them industrious, but to make them love industry; not only to make them virtuous, but to make them love virtue; not only to make them just, but to make them hunger and thirst after justice."
- John Ruskin (1819 - 1900)
