I think it would be worth the while to introduce a school of children to such [an oak grove], that they may get an idea of the primitive oaks before they are all gone, instead of hiring botanists to lecture to them when it is too late.
Henry David ThoreauNo method nor discipline can supersede the necessity of being forever on the alert. What is a course of history, or philosophy, or poetry, or the most admirable routine of life, compared with the discipline of looking always at what is to be seen? Will you be a reader, a student merely, or a seer?
