“To the illuminated mind the whole world burns and sparkles with light.”

“To a dull mind all of nature is leaden. To the illumined mind the whole world burns and sparkles with light.”

“The world we live in is but thickened light.”

“Every burned book or house enlightens the world; every suppressed or expunged word reverberates through the earth from side to side.”

“To different minds, the same world is a hell, and a heaven”

“It facilitates labor and thought so much that there is always the temptation in large schools to omit the endless task of meeting the wants of each single mind, and to govern by steam. But it is at frightful cost. Our modes of Education aim to expedite, to save labor; to do for masses what cannot be done for masses, what must be done reverently, one by one: say rather, the whole world is needed for the tuition of each pupil.”

“When the mind is braced by labor and invention, the page of whatever book we read becomes luminous with manifold allusion. Every sentence is doubly significant, and the sense of our author is as broad as the world.”
