Famous quotes containing the words stem and/or science:

“Ignorance, the root and stem of all evil.”

“The knowledge of an unlearned man is living and luxuriant like a forest, but covered with mosses and lichens and for the most part inaccessible and going to waste; the knowledge of the man of science is like timber collected in yards for public works, which still supports a green sprout here and there, but even this is liable to dry rot.”
—Henry David Thoreau (1817–1862)
