Famous quotes containing the word science:
“The present war having so long cut off all communication with Great-Britain, we are not able to make a fair estimate of the state of science in that country. The spirit in which she wages war is the only sample before our eyes, and that does not seem the legitimate offspring either of science or of civilization.”
—Thomas Jefferson (1743–1826)
“After sitting in my chamber many days, reading the poets, I have been out early on a foggy morning and heard the cry of an owl in a neighboring wood as from a nature behind the common, unexplored by science or by literature.”
—Henry David Thoreau (1817–1862)
