Famous quotes containing the words instruction and/or book:
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
“A book should contain pure discoveries, glimpses of terra firma, though by shipwrecked mariners, and not the art of navigation by those who have never been out of sight of land. They must not yield wheat and potatoes, but must themselves be the unconstrained and natural harvest of their author’s lives.”
—Henry David Thoreau (1817–1862)
