“People always ask us, “Are things better or worse today?” Well, some things are better and some things are worse.... But there are a lot of problems in the world today that no one dreamed of when we were young. For instance, this business about the environment. Why, clean water was just something you took for granted.”
—Sarah Delany (b. 1890)
“People disparage knowing and the intellectual life, and urge doing. I am content with knowing, if only I could know.”
—Ralph Waldo Emerson (1803–1882)
“Sweet smiling village, loveliest of the lawn,
Thy sports are fled and all thy charms withdrawn;
Amidst thy bowers the tyrant’s hand is seen,
And desolation saddens all thy green;
One only master grasps the whole domain,
And half a tillage stints thy smiling plain;”
—Oliver Goldsmith (1730?–1774)
